A

ADHD is one of the most common neurodevelopmental conditions, affecting an estimated 5-7% of children and 2-5% of adults worldwide. The name is misleading: people with ADHD don't have a deficit of attention—they have difficulty regulating where their attention goes. This means intense focus on engaging tasks (hyperfocus) can coexist with an inability to start or sustain effort on things that feel boring or unrewarding.

ADHD presents in three subtypes: predominantly inattentive (often missed in diagnosis, especially in women and girls), predominantly hyperactive-impulsive, and combined. In adults, hyperactivity often shows up as internal restlessness rather than the stereotypical "bouncing off the walls."

The core challenge isn't willpower—it's a neurological difference in dopamine regulation that affects motivation, time perception, emotional regulation, and working memory. Understanding this reframe is often transformative for people who've spent years blaming themselves for struggles that have a biological basis.

In Practice

  • You sit down to work on a report that's due tomorrow, but your brain keeps pulling you toward researching a completely unrelated topic that suddenly feels urgent and fascinating.
  • You've lost your keys for the third time this week—not because you don't care, but because your brain didn't flag "putting keys down" as important enough to record.

Commonly Confused With

Laziness

ADHD-related inaction comes from a neurological difficulty with task initiation and sustained effort, not from a lack of caring or motivation. The frustration people with ADHD feel about their own productivity is itself evidence that laziness isn't the issue.

Clinical Context

ADHD is recognized in the DSM-5 as a neurodevelopmental disorder with onset in childhood (symptoms present before age 12). Diagnosis requires symptoms in multiple settings that significantly impact functioning.

Community Note

Many adults, especially women and people of color, are diagnosed later in life after years of masking or being told they're "just not trying hard enough." Late diagnosis often brings a mix of grief and relief.

ADHD paralysis is the experience of being completely stuck—not because you don't want to act, but because your brain can't select a starting point. It shows up in three main forms: task paralysis (too many steps), choice paralysis (too many options), and emotional paralysis (feelings too big to think through).

This isn't procrastination in the traditional sense. Procrastination involves choosing to delay; ADHD paralysis feels involuntary. Your body won't move. Your thoughts loop without resolving. You might stare at a screen, scroll aimlessly, or literally freeze while your internal monologue screams at you to just do something.

The root cause is usually a combination of executive dysfunction (difficulty sequencing and prioritizing) and emotional overwhelm. When the brain can't rank what matters most, it defaults to doing nothing—which then triggers shame, which makes the paralysis worse.

In Practice

  • You have five things on your to-do list, all equally urgent. Instead of picking one, you spend two hours on your phone feeling guilty about all of them.
  • You need to reply to an important email but the "right" response feels so high-stakes that you draft nothing and avoid your inbox entirely.

Commonly Confused With

Procrastination

Procrastination is a choice to delay. ADHD paralysis is an inability to start, even when the person is desperate to act. The key difference is agency—paralysis removes it.

Community Note

Many people find that naming this experience—"I'm in paralysis right now"—is itself a coping tool. It replaces self-blame with recognition, which can sometimes break the loop.

Autistic burnout is distinct from general burnout or depression, though it can look similar from the outside. It's the cumulative result of years or months of masking, sensory overload, social demands, and the constant cognitive labor of translating between autistic and neurotypical ways of being.

During burnout, autistic people often experience a loss of skills they previously had—including speech, executive function, self-care, and social capacity. This isn't regression; it's a system that's been running on overdrive finally shutting down to protect itself.

Recovery requires significant reduction in demands, not just a vacation or a good night's sleep. Many autistic adults describe burnout cycles that last months or even years, especially when they don't have the language or support to recognize what's happening.

In Practice

  • After a year of pushing through a demanding job without accommodations, you find you can no longer handle grocery shopping, phone calls, or even conversations that used to feel manageable.
  • You used to be able to mask effectively in social settings. Now the effort feels physically painful and you need days to recover from a single dinner with friends.

Commonly Confused With

Depression

While autistic burnout can trigger depression, the root cause is different. Depression is a mood disorder; autistic burnout is a capacity crisis caused by sustained overload. The treatment approaches differ—burnout requires demand reduction, not just mood support.

Related Terms

Clinical Context

Autistic burnout is not yet a formal clinical diagnosis, but research by Raymaker et al. (2020) provided the first academic definition based on autistic adults' lived experiences.

Community Note

Many late-diagnosed autistic adults realize their previous "breakdowns" or "burnouts" were actually autistic burnout all along. Recognizing the pattern can be both validating and heartbreaking.

ADHD tax is a community-coined term for the extra costs—financial, emotional, and practical—that pile up because of executive dysfunction. Late fees because you forgot to pay a bill you could afford. Replacing lost items for the third time. Food that went bad because you forgot it was in the fridge. Subscriptions you've been meaning to cancel for months. Impulse purchases that seemed essential at 2 AM.

These costs are invisible to people who don't live with them. There's no line item in a budget for "things ADHD made more expensive." But they add up. Studies on the economic impact of ADHD consistently find higher costs of living across healthcare, lost productivity, and financial mismanagement—not because people with ADHD are irresponsible, but because systems like billing cycles, expiration dates, and cancellation processes assume a level of executive function that isn't universal.

The emotional ADHD tax is just as real: the shame of another missed deadline, the relationship strain from forgotten promises, the exhaustion of systems and workarounds that neurotypical people never need to build.

In Practice

  • You find a $47 late fee on your credit card for a payment you had the money for but forgot to make. You've set up autopay three times but somehow it never stuck.
  • You buy a replacement phone charger because you can't find the one you bought last week. It's the fourth charger you've purchased this year. It's February.

Community Note

The term went viral on social media because it names an experience that millions of people recognized instantly. For many, the relief of learning that this pattern has a name—and that other people share it—is worth more than any organizational hack.

Alexithymia literally means "no words for feelings." It describes the experience of having emotions but struggling to identify, label, or communicate them. You might feel something intense in your body—tightness in your chest, a knot in your stomach, a surge of energy—without being able to name it as anger, anxiety, excitement, or sadness.

Alexithymia affects roughly 50% of autistic people, compared to about 5-10% of the general population. It's not an autism-specific condition, but the overlap is significant enough that researchers now believe many emotional difficulties previously attributed to autism are actually driven by co-occurring alexithymia.

Living with alexithymia can be confusing and isolating. When someone asks "how are you feeling?" and you genuinely don't know, it can look like avoidance or disinterest. When your body is sending distress signals you can't decode, you might push through pain, hunger, or exhaustion without realizing you need to stop. Developing a vocabulary for bodily sensations—and learning to map them to emotions—is a common therapeutic approach.

In Practice

  • Your therapist asks what you're feeling and you go blank. It's not that you're suppressing anything—you genuinely can't tell. You know something is happening in your body, but you can't name it.
  • You don't realize you're angry until you snap at someone. Looking back, you can see the signs were building for hours, but in the moment, you couldn't read them.

Commonly Confused With

Not caring

People with alexithymia feel emotions just as deeply—sometimes more so. The difficulty is in identifying and articulating them, not in having them. A person who seems emotionally flat may be experiencing a storm they simply can't name.

Related Terms

Clinical Context

Research by Bird and Cook (2013) suggests that many emotional processing difficulties attributed to autism are more accurately explained by co-occurring alexithymia. Kinnaird et al. (2019) found alexithymia prevalence of approximately 50% in autistic populations.

Community Note

Many autistic people describe learning about alexithymia as a turning point—it explained why therapy approaches that relied on "just tell me how you feel" had never worked. Approaches that start with body sensations rather than emotion labels tend to be more effective.

Anxiety is one of the most common co-occurring conditions in neurodivergent people. Roughly 47% of adults with ADHD and 40-80% of autistic people meet criteria for an anxiety disorder. But neurodivergent anxiety often doesn't match the standard clinical picture, which means it gets missed, misdiagnosed, or treated with approaches that don't fit.

In ADHD, anxiety frequently stems from a lifetime of unpredictable executive function. When you've missed enough deadlines, forgotten enough commitments, and let enough people down—despite trying desperately not to—your nervous system starts anticipating failure everywhere. This isn't irrational anxiety. It's a learned response to real experience.

In autism, anxiety is often tied to unpredictability, sensory overload, social demands, and the constant cognitive labor of navigating a world built for different brains. What looks like "social anxiety" might actually be the very rational stress of trying to decode unwritten rules in real time while managing sensory input. The anxiety is real, but the root cause is environmental, not pathological.

In Practice

  • You check your email five times before sending it, not because you're a perfectionist, but because you've been misunderstood so many times that you're terrified of getting the tone wrong.
  • You cancel plans last-minute—not because you don't want to go, but because the number of unknowns (Will it be loud? Where will I park? What if the plans change?) feels unmanageable.

Commonly Confused With

Being "a worrier"

Neurodivergent anxiety isn't a personality trait. It's often a rational response to years of navigating systems that weren't built for your brain. Dismissing it as a character quirk misses the structural causes.

Related Terms

Clinical Context

Kessler et al. (2006) found that 47% of adults with ADHD met criteria for an anxiety disorder. Hollocks et al. (2019) found anxiety prevalence of 27-42% in autistic adults depending on measurement method.

Community Note

Many neurodivergent people describe their anxiety improving dramatically once they received their diagnosis and accommodations—evidence that the anxiety was situational, not inherent. Reducing demands and increasing support often does more than any medication alone.

"Actually Autistic" began as a hashtag (#ActuallyAutistic) used by autistic people on social media to distinguish their perspectives from the flood of content about autism produced by non-autistic parents, therapists, and organizations. The word "actually" is the point: it signals that the speaker is autistic themselves, not someone interpreting autism from the outside.

The movement emerged because autistic voices were—and often still are—marginalized in conversations about autism. Major autism organizations have historically been led by non-autistic people, research priorities have been set without autistic input, and public narratives about autism have centered the experiences of parents and caregivers rather than autistic people themselves. "Actually Autistic" was a reclamation: we exist, we speak for ourselves, and our perspectives matter more than anyone else's when the subject is our own lives.

The hashtag and community have created a massive body of first-person autism knowledge that challenges clinical assumptions, reframes "deficits" as differences, and provides a sense of belonging for newly diagnosed and self-identified autistic people.

In Practice

  • You search for autism resources online and find page after page written by clinicians and parents. Then you discover the #ActuallyAutistic hashtag and suddenly you're reading accounts from autistic people that describe your life better than any textbook ever did.
  • An autism organization shares an "awareness" campaign designed entirely by non-autistic people. Autistic community members respond with #ActuallyAutistic posts explaining why the campaign misrepresents their experience.

Related Terms

Community Note

The #ActuallyAutistic community operates on a core principle: nothing about us without us. This extends to research, policy, media representation, and therapeutic approaches. Autistic people are the experts on autistic experience.

Acquired neurodivergence refers to neurological differences that aren't present from birth but develop later due to brain injury, illness, or other medical events. Traumatic brain injury (TBI), stroke, long COVID, brain tumors, and certain infections can all produce lasting changes in cognition, sensory processing, executive function, and emotional regulation that overlap significantly with developmental neurodivergence.

The concept matters because conversations about neurodivergence have historically centered on conditions people are born with—autism, ADHD, dyslexia. But millions of people develop similar cognitive and sensory differences through acquired causes, and they often find more recognition and community in neurodivergent spaces than in traditional rehabilitation frameworks.

Including acquired neurodivergence in the broader conversation isn't about erasing the differences between developmental and acquired conditions—it's about acknowledging that the experience of having a brain that works differently from what society expects is shared across causes. The coping strategies overlap, the barriers overlap, and the need for accommodation and understanding overlaps.

In Practice

  • After a concussion, you develop sensory sensitivities and executive function difficulties that your doctor says should "resolve." A year later, they haven't. You find more useful coping strategies in ADHD and autism communities than in post-concussion resources.
  • You had COVID in 2021. Two years later, you still have brain fog, word-finding difficulties, and sensory overload. Nobody in your medical team uses the word "neurodivergent," but that's exactly what your experience has become.

Related Terms

Clinical Context

Traumatic brain injury alone affects approximately 69 million people worldwide annually (Dewan et al., 2018). Long COVID cognitive symptoms, sometimes called "brain fog," share features with ADHD and autism-related executive dysfunction.

Community Note

Some people with acquired neurodivergence feel uncertain about whether they "belong" in neurodivergent spaces. The growing consensus is that neurodivergence describes how your brain works now, not only how it was built—and that shared experience matters more than shared origin.

Auditory processing disorder (APD) is a condition where the brain has difficulty interpreting sounds, even though hearing itself is normal. A standard hearing test comes back fine, but in real-world situations—noisy restaurants, group conversations, lectures—speech becomes garbled, words blend together, and meaning gets lost.

APD frequently co-occurs with ADHD, autism, and dyslexia, and is significantly underdiagnosed because standard hearing tests don't catch it. The person hears the sounds; their brain just struggles to process them quickly and accurately enough for real-time comprehension. This often leads to asking people to repeat themselves, misunderstanding instructions, and appearing inattentive when in fact the person is straining to decode every word.

The experience is often described as trying to listen to a conversation underwater, or hearing every word individually but not being able to assemble them into meaning fast enough. Written communication, subtitles, and visual supports can make an enormous difference—not because the person can't understand language, but because the auditory channel is unreliable.

In Practice

  • Your colleague gives you verbal instructions in an open office. You hear the sounds perfectly—but by the time your brain processes the first sentence, they're on the third. You nod along and then immediately ask them to email the details.
  • You can't follow conversations in restaurants. Your friends think you're not listening. You're listening harder than anyone else at the table—your brain just can't separate their voice from the clanking dishes and background music.

Commonly Confused With

Hearing loss

Hearing loss is a problem with the ears detecting sound. APD is a problem with the brain interpreting sound. The distinction matters because hearing aids don't help APD—the signal is getting through; the processing is where it breaks down.

Related Terms

Clinical Context

APD is diagnosed through specialized audiological testing that goes beyond standard hearing assessments. The American Academy of Audiology recognizes APD as a distinct condition, though diagnostic criteria and terminology continue to evolve.

Community Note

Many people with APD develop coping strategies without ever being diagnosed—lip-reading, always choosing quiet venues, pretending to understand when they don't. Learning that there's a name for this experience often brings the same relief as any other neurodivergent diagnosis.

Autistic inertia describes the difficulty many autistic people have with initiating action, stopping an activity in progress, or transitioning between tasks. It's the experience of knowing what you need to do but being unable to get your body or mind to change course—as if you're an object at rest that requires enormous force to start moving, or an object in motion that can't stop.

This differs from ADHD paralysis in important ways. ADHD paralysis is often driven by overwhelm, decision fatigue, or lack of dopamine motivation. Autistic inertia is more about the difficulty of state-change itself. Transitioning from one activity to another—even a preferred activity—requires a kind of cognitive gear-shifting that doesn't happen automatically. The person may need significant lead time, preparation, and sometimes external support to make the switch.

Autistic inertia can also work in the other direction: once engaged in an activity, an autistic person may be unable to stop even when they want to, because disengaging requires the same state-change that's difficult in all directions. This isn't stubbornness—it's a neurological difficulty with transitions.

In Practice

  • You've been sitting on the couch for two hours. You need to shower. You want to shower. There's nothing wrong. But the act of getting up, walking to the bathroom, and initiating the sequence of showering feels like it requires moving a mountain. Eventually someone walks by and the movement breaks the spell.
  • You're deep in a project and someone tells you dinner is ready. You hear them. You understand. But it takes twenty minutes of gradual mental disengagement before you can actually stand up and walk to the table.

Commonly Confused With

ADHD paralysis

ADHD paralysis involves being overwhelmed by options or unable to prioritize. Autistic inertia is about the difficulty of state-change itself—starting, stopping, or switching—regardless of how many options or how much overwhelm is involved.

Related Terms

Community Note

Autistic inertia is one of the most universally recognized experiences in autistic communities but one of the least studied clinically. Many autistic people describe it as the single most impactful daily challenge—more than sensory issues or social difficulties.

Autistic joy is the experience of intense, often overwhelming happiness that many autistic people describe in connection with their special interests, favorite sensory experiences, moments of genuine connection, or encounters with beauty and pattern. It can involve hand-flapping, bouncing, squealing, full-body stimming, or quiet, focused absorption—the expression varies, but the intensity is characteristic.

Mainstream narratives about autism focus almost exclusively on challenges: social difficulties, sensory overload, communication barriers, meltdowns. Autistic joy is the deliberate counter-narrative—a reminder that autistic experience includes not just different kinds of suffering but different kinds of happiness. The same neurology that produces intense distress also produces intense delight.

Autistic joy often shows up in ways that neurotypical social norms discourage. Hand-flapping in public, talking at length about a niche interest, making sounds of delight—these expressions of joy are the same behaviors that masking teaches autistic people to suppress. Unmasking often means reconnecting with this capacity for intense positive experience.

In Practice

  • You discover a new fact about your special interest and the excitement is so intense that you bounce on your toes and flap your hands. For that moment, you feel more alive and present than you have all week.
  • Your autistic child sees a train and their whole body lights up—they stim, laugh, and start reciting every train fact they know. A stranger looks concerned. You know this is what pure, unfiltered joy looks like in your child's body.

Related Terms

Community Note

The #AutisticJoy hashtag emerged as a direct counter to deficit-based narratives. Autistic advocates argue that any framework for understanding autism that doesn't include joy is incomplete—and that therapies aimed at eliminating joyful stims are taking away something precious.

The accommodation vs cure debate is the central philosophical divide in how society approaches neurodivergence. The cure model says the goal should be to eliminate or minimize neurological differences—to make neurodivergent people function as neurotypically as possible. The accommodation model says the goal should be to change environments, systems, and expectations so that neurological differences aren't disabling.

This isn't an abstract debate. It shapes everything from how therapies are designed (eliminate autistic behaviors vs support autistic people), how schools operate (remediate differences vs provide alternative pathways), how workplaces function (require conformity vs design for diversity), and how research funding is allocated (cure-focused vs quality-of-life focused).

Most neurodivergent self-advocates favor accommodation over cure, arguing that many of their difficulties come from environmental mismatch rather than intrinsic deficiency. This doesn't mean all neurodivergent people reject medical support—many benefit from medication, therapy, and specific interventions. The distinction is between support that helps a person thrive as they are and interventions aimed at making them someone they're not.

In Practice

  • A parent is offered ABA therapy to teach their autistic child to stop hand-flapping. They ask: "Why? The flapping doesn't hurt anyone—it helps them regulate. Can we instead teach the classroom to accept it?" That question is the accommodation model in action.
  • A company offers a "neurodiversity training" program that teaches neurodivergent employees to fit neurotypical communication norms. A neurodivergent employee suggests redesigning the communication norms instead. Same problem, fundamentally different approaches.

Related Terms

Community Note

The "cure" framing is especially contested in autistic communities, where many people view autism as an identity rather than a disease. The question "would you cure your autism?" often receives the response: "You can't separate the autism from the person—to cure it would be to create a different person."

Body doubling is the practice of having another person present while you work, not to help or supervise, but simply to exist nearby. For many people with ADHD, the passive presence of another person provides just enough external accountability and stimulation to keep executive function engaged.

This works because ADHD brains often struggle with self-directed motivation but respond well to social context. The other person doesn't need to be doing the same task, talking to you, or even paying attention to you—their presence alone changes the neurological equation.

Body doubling can happen in person (a friend doing their own work at the same table) or virtually (video calls where both people work silently, or platforms designed specifically for this). It's one of the most accessible and effective ADHD strategies, yet it's rarely mentioned in clinical settings.

In Practice

  • You can't seem to fold laundry alone, but when your partner is sitting on the couch reading, suddenly the task feels doable.
  • You join a virtual co-working session where strangers work on camera together in silence—and you get more done in two hours than you have all week.

Related Terms

Community Note

Body doubling has exploded in popularity through ADHD communities on social media and dedicated platforms like Focusmate. Many people describe it as a revelation—finally understanding why they could only study in coffee shops or libraries.

Burnout in the neurodivergent context goes beyond workplace stress. It's the cumulative result of running a brain that requires more energy for everyday tasks—masking, managing sensory input, compensating for executive dysfunction, navigating social expectations—without adequate recovery time. The demands don't have to be extraordinary; they just have to exceed your capacity for long enough.

Neurodivergent burnout differs from general burnout in important ways. Recovery takes longer because the underlying energy demands don't disappear with a vacation. The triggers are often invisible to others (sensory environments, social performance, cognitive compensation), which means the burnout itself is frequently dismissed as laziness, weakness, or lack of resilience.

The relationship between burnout and autistic burnout is worth noting: autistic burnout is a specific pattern involving skill loss and reduced tolerance, while broader neurodivergent burnout may present as chronic fatigue, brain fog, emotional numbness, increased sensitivity, and a collapse of coping strategies. Both involve a system that's been running too hard for too long.

In Practice

  • You used to manage your ADHD with elaborate systems—lists, alarms, routines. After months of sustained pressure, the systems collapse. You can't rebuild them because you don't have the executive function to build systems about executive function.
  • You take a week off work feeling completely depleted. By Wednesday you feel slightly better. By Monday morning you're back to zero. The math doesn't work because the demands waiting for you haven't changed.

Commonly Confused With

Autistic burnout

Autistic burnout is a specific pattern that includes loss of previously held skills and is caused by the cumulative toll of masking and navigating neurotypical environments. General neurodivergent burnout is broader and can affect anyone whose brain requires extra energy for daily functioning.

Related Terms

Community Note

Many neurodivergent people describe a cycle: push hard, crash, partially recover, push hard again. Breaking this cycle usually requires structural changes—not just self-care, but genuinely reducing demands—which often means uncomfortable conversations about capacity and accommodation.

Cognitive load refers to the total amount of mental processing your brain is handling at any given time. Everyone has a limited capacity, but for neurodivergent people, the baseline load is often higher because tasks that are automatic for neurotypical brains require conscious effort.

Consider a simple meeting: a neurotypical person might just listen and respond. An autistic person might be simultaneously processing sensory input, monitoring their facial expressions, interpreting social cues that don't come naturally, suppressing stims, and managing anxiety—all while trying to follow the actual content. The "same" meeting is a fundamentally different cognitive experience.

This is why neurodivergent people can be exhausted by activities that seem effortless to others. It's not about stamina or attitude—it's about how much invisible processing is happening behind the scenes. Reducing cognitive load through accommodations, routine, and environmental control isn't laziness. It's smart resource management.

In Practice

  • After a day of navigating social interactions, processing fluorescent lighting, and suppressing stims at work, you get home and can't even decide what to eat. Your cognitive load has been at maximum all day—there's nothing left.
  • You need complete silence to do math that other people can do with music playing. The math itself isn't harder for you—but the sensory filtering uses bandwidth that other brains get for free.

Coprolalia is a specific type of vocal tic involving the involuntary production of obscene, profane, or socially taboo words or phrases. It's the single most recognized—and most misunderstood—feature of Tourette syndrome, largely because of how it's portrayed in media. In reality, coprolalia affects only about 10-15% of people with Tourette's.

The mechanism behind coprolalia isn't fully understood, but it appears related to how the brain inhibits context-inappropriate responses. Everyone has intrusive thoughts about saying the wrong thing at the wrong moment. In coprolalia, the inhibition system that normally suppresses those impulses doesn't engage reliably. The words that emerge are often the exact words the person least wants to say—precisely because the brain flags them as forbidden.

The social impact is enormous. Coprolalia can make public spaces, workplaces, and schools feel hostile or impossible to navigate. People with coprolalia often experience intense shame, social isolation, and misunderstanding—not because of the tics themselves, but because of how others react to them.

In Practice

  • You're in a quiet waiting room and your brain produces exactly the word you most desperately don't want to say. The effort of suppressing it takes all your concentration, and it still comes out as a whispered fragment.
  • Someone learns you have Tourette's and immediately asks if you swear uncontrollably. You explain that most people with Tourette's don't have coprolalia—but the conversation is already shaped by the stereotype.

Commonly Confused With

Choosing to swear

Coprolalia is involuntary—the words are produced against the person's will and often cause them significant distress. It's the opposite of choosing to swear; the person would do anything to stop.

Related Terms

Clinical Context

Coprolalia is classified as a complex vocal tic. Research suggests it involves dysfunction in the basal ganglia-thalamo-cortical circuits that regulate impulse suppression. It is neither required for nor exclusive to a Tourette syndrome diagnosis.

Community Note

The Tourette community has long pushed back against media portrayals that reduce the condition to coprolalia. When the only representation is the most dramatic symptom, it distorts public understanding and makes life harder for everyone with tics—whether or not they have coprolalia.

Context blindness describes the difficulty many autistic people have with automatically transferring knowledge, skills, or rules from one context to another. A person might master a math concept at home with a tutor but be unable to apply it on a school test. They might understand social rules in one friend group but struggle to adapt them to a different social setting. The knowledge exists—but it's stored with its original context attached, and extracting it for use elsewhere requires conscious effort.

This differs from a learning deficit. The person has genuinely learned the material or skill. But while neurotypical brains automatically abstract and generalize, autistic brains often encode information context-specifically. The classroom, the teacher, the time of day, the format of the question—all of these become part of how the knowledge is stored and accessed.

Context blindness has practical implications for education, work, and daily life. It means that "you know this—you did it yesterday" is a frustrating and unhelpful thing to hear, because knowing something in one context doesn't guarantee access to it in another. Effective support involves explicitly teaching transfer—helping the person see how the same principle applies across different settings.

In Practice

  • You learned to navigate small talk at your last job. At your new job, you're starting from scratch—the rules feel completely different even though they're essentially the same. The old scripts don't feel transferable to new people and a new environment.
  • Your child can solve fractions in their workbook at home but fails the same problems on a classroom test. The test looks different, the room is different, and the knowledge that was available at the kitchen table isn't accessible at a school desk.

Related Terms

Clinical Context

The concept of context blindness in autism was described by Peter Vermeulen (2012), who proposed it as a key cognitive feature that explains many autistic challenges with generalization, flexibility, and social understanding.

Compensation strategies are the systems, habits, and behaviors neurodivergent people develop to manage or hide their differences. They include everything from elaborate reminder systems for executive dysfunction, to memorized social scripts for autism, to reading lips to compensate for auditory processing differences. They work—often well enough that nobody realizes there's a difference being managed.

The problem with compensation is its invisibility. When strategies are effective, the person appears to function "normally," which leads to three damaging conclusions: they don't need support, they're not "really" neurodivergent, and if they struggle, they're not trying hard enough. The effort behind the performance remains unseen.

Compensation also has a shelf life. Strategies that work in high school may not survive college. Coping mechanisms that managed a structured job may collapse in a role with more ambiguity. Major life transitions—parenthood, career changes, health challenges—often overwhelm established compensation strategies, leading to what looks like sudden decline but is actually the failure of a system that was always running on overtime.

In Practice

  • You have seventeen alarms, three calendar systems, and a notebook full of routines that keep your life running. Nobody sees the infrastructure. They just see someone who "seems fine"—and they conclude that your ADHD can't be that bad.
  • After years of effective masking and compensating, you burn out and your coping systems collapse. Your therapist says you seem "suddenly worse." You weren't worse—you just ran out of the energy that made you look better.

Community Note

Compensation is often the reason people are diagnosed late. The better your strategies, the less visible your differences, and the less likely anyone is to suggest assessment. Many late-diagnosed adults describe feeling like their compensation was finally "seen" only when it stopped working.

Co-occurring conditions (also called comorbidities, though many communities prefer the less pathologizing term) refers to the frequent overlap of multiple neurodivergent conditions in the same person. The numbers are striking: about 50-70% of people with ADHD also meet criteria for at least one other condition. More than 70% of autistic people have at least one co-occurring condition. Dyslexia and ADHD co-occur in 20-40% of cases.

This isn't coincidence. Many neurodivergent conditions share underlying neurological features—differences in executive function, sensory processing, dopamine regulation, and neural connectivity. The boundaries between conditions are often blurrier than diagnostic categories suggest. A person might have executive dysfunction that looks like ADHD, sensory differences that look like autism, and reading difficulties that look like dyslexia—and all three might be aspects of the same neurological variation.

Understanding co-occurrence matters because treatment and support need to address the full picture. Treating ADHD without accounting for co-occurring anxiety may not work. Supporting autism without recognizing co-occurring ADHD misses half the challenge. The most effective approaches see the whole person, not a list of separate diagnoses.

In Practice

  • You get diagnosed with ADHD and start medication. Some symptoms improve dramatically, but others don't budge. It takes another two years to discover you're also autistic, and the unresolved symptoms make much more sense through that lens.
  • Your child's psychologist says they have "just ADHD." But the sensory sensitivities, the rigid routines, and the social exhaustion don't fit neatly into that box. You push for a broader evaluation and discover autism was there all along.

Related Terms

Clinical Context

Research consistently shows high rates of co-occurrence across neurodevelopmental conditions. The National Comorbidity Survey Replication found that 89% of adults with ADHD had at least one co-occurring psychiatric condition.

Community Note

The neurodivergent community increasingly uses terms like "co-occurring" and "overlapping" instead of "comorbid" because the latter implies each condition is a separate disease rather than an interconnected aspect of the same neurological variation.

Capacity fluctuation describes the experience of having significantly different levels of cognitive, emotional, and functional ability from one day to the next—or even within the same day. Monday you might handle a complex project, a social dinner, and household chores with energy to spare. Tuesday the same tasks feel impossible, and getting out of bed is a genuine achievement. Both days are real.

This inconsistency is one of the most misunderstood aspects of neurodivergence. When people see you functioning well on Monday, they set that as the baseline and interpret Tuesday as failure, laziness, or attention-seeking. The truth is that neurodivergent capacity is affected by sleep quality, sensory load, social demands, hormonal fluctuations, accumulated stress, and dozens of other variables that neurotypical capacity is more resilient to.

Capacity fluctuation creates a specific kind of suffering: the inability to trust your own abilities. You can't commit to plans because you don't know which version of your capacity will show up. You can't explain the inconsistency to employers or friends because "I could do it yesterday but I can't today" sounds like an excuse rather than a neurological reality.

In Practice

  • Last week you cleaned the entire apartment, cooked dinner, and did laundry. This week you can barely make a sandwich. Your partner's frustration is visible: "You did it fine last week." You did. And today you can't.
  • You hesitate to accept an invitation three weeks from now because you genuinely don't know if you'll have the capacity when the day arrives. You've canceled enough times to know that promising and failing feels worse than declining upfront.

Related Terms

Community Note

The phrase "some days I can, some days I can't" is used widely in neurodivergent communities as both a statement of reality and a request for understanding. Accepting capacity fluctuation—rather than fighting it—is often the first step toward sustainable self-management.

Dopamine is a chemical messenger in the brain that plays a central role in motivation, reward processing, attention, and movement. In the context of neurodivergence, dopamine differences help explain why ADHD brains struggle with tasks that feel unrewarding and hyperfocus on tasks that feel interesting.

It's important to understand what dopamine actually does: it doesn't create pleasure. It creates the anticipation of reward—the feeling that something is worth pursuing. When dopamine signaling is lower (as research suggests in ADHD), the brain struggles to generate motivation for tasks that don't have an immediate, compelling payoff. This is why a person with ADHD can play a video game for six hours but can't start a five-minute chore.

This isn't a character flaw—it's neurochemistry. ADHD medications (stimulants like methylphenidate and amphetamines) work primarily by increasing dopamine availability in the prefrontal cortex, which is why they help with focus and task initiation.

In Practice

  • You know you need to pay a bill that will take three minutes, but your brain treats it like it requires climbing a mountain—because the task has no dopamine reward attached to it.
  • You discover a new hobby and spend 12 hours learning everything about it in one sitting. Three weeks later, the interest vanishes completely. Your dopamine system moved on.

Clinical Context

Research consistently shows differences in dopamine transporter density and dopamine receptor availability in people with ADHD, particularly in the prefrontal cortex and basal ganglia (Volkow et al., 2009).

Dyslexia is a neurological difference in how the brain processes written language. People with dyslexia often have difficulty decoding words, reading fluently, and spelling accurately—but these challenges exist alongside (and sometimes because of) strengths in big-picture thinking, problem-solving, spatial reasoning, and verbal communication.

Dyslexia isn't about seeing letters backward, despite the popular myth. It's primarily a phonological processing difference—the brain has difficulty mapping sounds to letters and letter patterns. This makes the mechanics of reading effortful in a way that's invisible to people who read automatically. Imagine trying to read a paragraph where every word requires conscious effort to decode. That's the cognitive load many dyslexic readers navigate daily.

An estimated 15-20% of the population has some degree of dyslexia, making it one of the most common neurodivergent conditions. Early identification and the right support (structured literacy approaches, assistive technology, accommodations) can make an enormous difference—but many people aren't identified until adulthood, if at all.

In Practice

  • You read the same paragraph three times and still can't retain the information—not because you aren't paying attention, but because the decoding process uses so much mental energy that comprehension suffers.
  • You're a brilliant verbal communicator who regularly impresses people in meetings, but writing a simple email takes 45 minutes because you second-guess every word's spelling.

Commonly Confused With

Low intelligence

Dyslexia has no connection to intelligence. Many dyslexic people are highly intelligent—the difficulty is specifically with written language processing, not thinking or understanding.

Related Terms

Clinical Context

Dyslexia is classified as a Specific Learning Disorder with impairment in reading in the DSM-5. Diagnosis typically involves psychoeducational testing that measures reading skills relative to cognitive ability.

Community Note

Many dyslexic adults describe a "two-world" experience—being seen as capable and smart in person, then being judged as careless or lazy when their written work doesn't match. The gap isn't about effort; it's about how the brain works.

Dyspraxia (clinically known as Developmental Coordination Disorder, or DCD) affects the brain's ability to plan and coordinate physical movements. It's not a muscle problem—it's a communication problem between the brain and the body. The person knows what they want to do, but the motor planning required to execute it smoothly doesn't come automatically.

This can affect fine motor skills (handwriting, buttoning shirts, using utensils), gross motor skills (running, catching, balance), and motor planning (learning new physical sequences, navigating unfamiliar spaces). Many people with dyspraxia also experience difficulties with spatial awareness, time management, and organization—suggesting the coordination challenges extend beyond just movement.

Dyspraxia frequently co-occurs with ADHD, autism, and dyslexia. It's significantly underdiagnosed, especially in adults, partly because it's often dismissed as "clumsiness" and partly because many people develop elaborate compensatory strategies that mask the underlying difficulty.

In Practice

  • You bump into doorframes, knock over glasses at dinner, and trip on flat surfaces—not because you're not paying attention, but because your spatial awareness and motor planning don't sync up reliably.
  • Learning to drive took you three times longer than your peers. Each step (mirror, signal, maneuver) required conscious effort that others seemed to do automatically.

Related Terms

Clinical Context

DCD is recognized in the DSM-5 as a motor disorder with onset in early development. Diagnosis requires motor coordination substantially below expected levels given age and opportunity for skill learning.

Community Note

Many adults with dyspraxia say the hardest part isn't the physical coordination—it's the constant low-level anxiety of navigating a world designed for people whose bodies cooperate automatically.

Dyscalculia is a specific learning difference that affects how the brain processes numerical information. People with dyscalculia often struggle with number sense (the intuitive understanding of what numbers mean and how they relate), math fact retrieval (remembering that 7 x 8 = 56), and mathematical procedures (carrying, borrowing, multi-step problems).

Like dyslexia, dyscalculia has nothing to do with intelligence. A person can be a brilliant writer, lawyer, or artist and still genuinely struggle to split a restaurant bill or read an analog clock. The difficulty is specific to how the brain represents and manipulates numerical quantities.

Dyscalculia is estimated to affect 3-7% of the population but is significantly less researched and recognized than dyslexia. Many people with dyscalculia go undiagnosed and internalize the belief that they're "just bad at math"—when in reality, they have a neurological difference that benefits from specific support and accommodations.

In Practice

  • You're an accomplished professional, but you still count on your fingers and feel a wave of anxiety when someone suggests splitting the check. Mental arithmetic feels like trying to hold water in your hands—the numbers slip away.
  • You were told you were "lazy" or "not trying" in math class, when the truth was that no amount of practice could make times tables stick in your memory the way they did for other students.

Related Terms

Clinical Context

Dyscalculia is classified as a Specific Learning Disorder with impairment in mathematics in the DSM-5. It can affect number sense, math fact memorization, accurate calculation, and mathematical reasoning.

Community Note

Dyscalculia is sometimes called the "forgotten learning disability" because it receives far less attention, research funding, and educational support than dyslexia—even though its impact on daily life can be just as significant.

Decision fatigue is the well-documented phenomenon where the quality of your decisions degrades after making many of them. Every choice—from what to eat for breakfast to how to respond to an email—draws from a finite cognitive reserve. When that reserve runs low, you either make poor choices or stop making choices altogether.

For neurodivergent people, especially those with ADHD, decision fatigue can hit faster and harder. When your brain already struggles with prioritization and evaluation, every decision costs more cognitive effort than it would for someone whose executive function handles it automatically. A neurotypical person might breeze through 20 small decisions before lunch; an ADHD brain might be depleted after five.

This is why many neurodivergent people develop systems to reduce daily decisions: meal planning, capsule wardrobes, routines, and default choices. It's not rigidity—it's resource management.

In Practice

  • By mid-afternoon, you can't decide what to have for dinner. Not because you're not hungry, but because you've already made so many decisions today that your brain has stopped cooperating with new ones.
  • You're shopping for a new phone. After comparing five models across eight features, you either buy the first one you see or leave the store with nothing—both results of a decision-making system that's run out of fuel.

Dysgraphia is a neurological condition that affects the ability to write. This can manifest as difficulty with handwriting (letter formation, spacing, sizing), spelling, or the ability to organize and express thoughts in written form—or all three. The challenge isn't about intelligence or effort; it's about how the brain coordinates the complex motor and cognitive processes involved in writing.

Handwriting-related dysgraphia involves fine motor coordination: the brain has difficulty directing the hand to form letters consistently. People with this form often produce writing that's illegible, inconsistently sized, or physically painful to produce. Expressive dysgraphia involves difficulty translating thoughts into written language—a person may be an eloquent speaker but produce disorganized, incomplete writing that doesn't reflect their actual thinking.

Dysgraphia often co-occurs with dyslexia, ADHD, and autism, but it's a distinct condition. Many people with dysgraphia benefit from typing instead of handwriting, speech-to-text tools, graphic organizers for writing tasks, and extended time on written assignments.

In Practice

  • Your handwriting is illegible even to you. You grip the pen so tightly your hand cramps after a paragraph. People assume you're careless, but the physical act of writing is genuinely effortful for your brain and body.
  • You can explain a concept clearly in conversation, but when asked to write it down, the ideas seem to evaporate. The gap between your verbal ability and written output frustrates you and confuses everyone else.

Related Terms

Clinical Context

Dysgraphia falls under the DSM-5 category of Specific Learning Disorder with impairment in written expression. It can affect handwriting, spelling, grammar, punctuation, and/or clarity of written expression.

Community Note

In an increasingly digital world, many people with dysgraphia find that typing reduces their barriers significantly. The push for handwriting-based assessment in schools remains a significant accessibility issue.

The double empathy problem, proposed by Dr. Damian Milton in 2012, challenges one of the most persistent assumptions about autism: that autistic people lack empathy or social understanding. Milton's argument is simple but revolutionary—when two people have very different ways of experiencing the world, they'll both struggle to understand each other. The difficulty is mutual, not one-sided.

Traditional autism research framed communication difficulties as an autistic deficit: autistic people fail to read social cues, miss nonverbal signals, and don't understand others' perspectives. The double empathy problem flips this by pointing out that non-autistic people are equally bad at reading autistic communication styles, understanding autistic perspectives, and interpreting autistic social cues. The difference is that only one group gets pathologized for it.

Research supports this reframe. Studies have shown that autistic people communicate effectively with other autistic people, and that non-autistic people struggle to read autistic emotions and intentions. The "empathy deficit" dissolves when you stop measuring autistic people against a neurotypical standard and start looking at the interaction itself.

In Practice

  • You communicate clearly and directly with your autistic friend, and the conversation flows naturally. In the same week, a neurotypical colleague completely misreads your tone in an email. The "social skills deficit" starts looking like a compatibility issue.
  • A clinician tells a parent their autistic child "doesn't understand others' feelings." But the child reads other autistic children just fine—it's only the neurotypical communication style that trips them up.

Community Note

The double empathy problem has become a cornerstone of autistic self-advocacy. It shifts the conversation from "autistic people need social skills training" to "everyone needs to learn how to communicate across neurotypes."

Disclosure is the act of telling someone—an employer, a teacher, a friend, a date—about your neurodivergent condition. It sounds straightforward, but for most neurodivergent people it's a complex risk-reward calculation that gets recalculated with every new person, every new context, and every new experience of how the information was received.

The potential benefits are significant: legal protections under disability law, access to reasonable accommodations, the ability to explain your needs openly, and the relief of not hiding. The potential costs are equally real: stigma, being seen as less capable, having your behavior over-attributed to your diagnosis ("oh, that's just their ADHD"), or losing opportunities that would have been available if you'd stayed quiet.

There's no formula. Some people disclose upfront and find it liberating. Others disclose only when they need specific accommodations. Many never disclose at work at all, choosing to manage privately and absorb the cost of masking. The right answer depends on the workplace culture, the specific people involved, the legal protections available, and the person's own comfort and safety.

In Practice

  • You're deciding whether to mention your ADHD to your new manager. The previous one used it against you in a performance review. The new one seems more understanding, but the memory makes you hesitate.
  • A student discloses their dyslexia to get exam accommodations. The process requires documentation, meetings, and forms—a bureaucratic tax that neurotypical students never have to pay for the same education.

Related Terms

Clinical Context

Under the Americans with Disabilities Act, employees are not required to disclose a diagnosis to receive accommodations—they need only describe the functional limitation. The interactive accommodation process is meant to be collaborative, not interrogative.

Community Note

The disclosure conversation is heavily shaped by privilege. People with stable employment, supportive managers, and visible identities that already face less bias have an easier time disclosing. For many, the decision is less about preference and more about safety.

In neurodivergent spaces, "disability" is a word that carries weight, nuance, and sometimes disagreement. Some neurodivergent people identify as disabled; others don't. Both positions are valid, and the conversation between them is one of the most important in the community.

Under the social model, disability isn't a characteristic of a person—it's a product of the mismatch between a person and their environment. An autistic person who works from home, controls their sensory environment, and communicates on their own terms might not feel disabled at all. Put that same person in an open-plan office with fluorescent lights and mandatory team-building activities, and they become profoundly disabled—not because they changed, but because the environment did.

The word also carries legal significance. In many countries, identifying as disabled unlocks protections and accommodations under disability law. Rejecting the label can mean rejecting those protections. This creates a tension for neurodivergent people who don't feel disabled in their daily lives but need the legal framework that the word provides.

In Practice

  • You hesitate to check "disabled" on a form because some days you function just fine. But the form isn't asking about your best days—it's asking whether your brain works differently enough to need support, and the answer is yes.
  • A colleague says "I don't think of you as disabled" as a compliment. You hear: "I don't want to think about what you're actually dealing with." The word isn't an insult—it's a description of your relationship to a system that wasn't built for you.

Related Terms

Community Note

There's no correct answer to whether any individual neurodivergent person is "disabled." The value of the word is in what it makes visible: that the world is built for some brains and not others, and that the gap between the two is where suffering lives.

Dissociation is the experience of feeling detached from yourself, your body, your emotions, or your surroundings. It can range from mild (zoning out, feeling "not quite here") to severe (losing time, feeling like you're watching yourself from outside your body, not recognizing your own reflection). It's a protective mechanism—the brain's way of creating distance when experience becomes too intense to process.

For neurodivergent people, dissociation often serves as an automatic response to sensory overload, emotional overwhelm, or sustained masking. When the nervous system is flooded with more input than it can handle, dissociation reduces the volume on everything—sensation, emotion, connection, presence. It's effective in the moment but costly over time, because you can't selectively numb. When you dissociate from distress, you also dissociate from connection, pleasure, and engagement.

Dissociation is distinct from autistic shutdown, though they can overlap. Shutdown is a response to overload that primarily affects the ability to function (speak, move, process). Dissociation is a response that primarily affects the sense of being present and connected. Some people experience both simultaneously.

In Practice

  • You're in a loud, bright, crowded space and suddenly everything feels distant—like you're watching the room through a window. Your body is there but "you" aren't. An hour later, you can't remember the details of conversations you participated in.
  • After a difficult meeting, you drive home on autopilot and realize you have no memory of the drive. You weren't asleep—your brain was protecting you from processing something it wasn't ready for.

Commonly Confused With

Shutdown

Shutdown involves a loss of functional capacity—difficulty speaking, moving, or processing. Dissociation involves a loss of presence and connection. Both are protective responses to overload, but they target different systems.

Related Terms

Clinical Context

Dissociation exists on a spectrum from normal (daydreaming, highway hypnosis) to clinical (depersonalization-derealization disorder, dissociative identity disorder). In neurodivergent populations, subclinical dissociation is common and often underrecognized.

A doom box (or doom pile, doom bag, doom drawer) is an accumulation of items that don't have a clear home. Mail, receipts, keys, chargers, random objects from your pockets, things you meant to put away but couldn't decide where—they all end up in the same spot because the organizational decision required to sort them exceeds your available executive function in the moment.

The term comes from ADHD communities and captures both the behavior and the emotional weight. The pile starts small and manageable. Then it grows. Then it becomes so overwhelming that sorting it feels impossible—so you avoid it, which makes it grow more. Eventually you either have a burst of hyperfocus energy and clear it all at once, or you dump the whole thing into a bigger container and start over. Many people with ADHD have multiple doom locations operating simultaneously.

Doom boxes aren't a character flaw. They're a predictable outcome of executive dysfunction meeting the constant stream of objects that daily life generates. Every item requires a micro-decision (where does this go?), and ADHD brains deplete their decision-making capacity faster than neurotypical brains. The doom box is what happens when the capacity runs out but the objects keep arriving.

In Practice

  • You have a chair in your bedroom that hasn't been visible in months. It's covered in clothes that are too clean for the hamper but too worn for the closet—a decision your brain cannot resolve, so the pile grows.
  • You buy a new organizer, spend a Saturday sorting everything, and feel amazing. Three weeks later, a new doom pile has formed on top of the organizer. The problem was never the container—it was the executive function required to use it consistently.

Related Terms

Community Note

The term "doom box" went viral because it named something millions of people experienced but had never heard described. The humor helps too—laughing about the doom pile is healthier than drowning in shame about it.

Executive function is the brain's project manager: it handles planning, prioritizing, sequencing, time management, working memory, impulse control, and emotional regulation. Executive dysfunction means this system doesn't work reliably—not because you're not smart enough, but because the neurological wiring works differently.

Executive dysfunction can look like forgetting appointments five minutes after scheduling them, being unable to break a big project into steps, struggling to switch between tasks, or knowing exactly what you need to do but being physically unable to start. It's one of the most common and most misunderstood aspects of ADHD, autism, and other neurodivergent conditions.

The key insight is that executive dysfunction is situational and variable. You might manage a complex project at work with ease on Monday and be unable to make a sandwich on Tuesday. This inconsistency often leads to accusations of laziness or "not trying," when in reality it reflects how executive function fluctuates with energy, stress, sleep, and interest levels.

In Practice

  • You need to clean the kitchen, but you can't figure out whether to start with dishes, counters, or the floor—so you stand in the doorway for ten minutes and then walk away.
  • You have a project due in a month. You know you should start. You think about starting every day. You begin working on it the night before it's due.

Commonly Confused With

Laziness

Laziness implies you could do the thing but choose not to. Executive dysfunction means the bridge between intention and action is unreliable. The frustration and guilt people feel about it is proof that motivation is there—the wiring is the problem.

Low intelligence

Executive function and intelligence are separate systems. Many people with executive dysfunction are highly intelligent—the gap between their ideas and their output is itself a hallmark of the condition.

Related Terms

Clinical Context

Executive function deficits are documented across ADHD, autism, traumatic brain injury, and other conditions. They involve the prefrontal cortex and its connections to other brain regions.

Emotional dysregulation means your emotional responses are harder to control, more intense, and slower to resolve than what's considered typical. For many neurodivergent people, emotions arrive fast, hit hard, and take a long time to settle—even when the logical brain knows the reaction is disproportionate.

This isn't about being "dramatic" or "overly emotional." Research shows that ADHD involves genuine differences in the brain regions responsible for emotional regulation (the prefrontal cortex and amygdala). Autistic people may experience alexithymia (difficulty identifying emotions) alongside intense emotional responses, creating a confusing internal landscape.

Emotional dysregulation is one of the most impactful yet least-discussed aspects of neurodivergence. It affects relationships, work performance, self-image, and daily decision-making. When your emotional thermostat doesn't have fine-grained controls, everything feels like it's set to either "off" or "maximum."

In Practice

  • A minor frustration—a slow driver, a dropped glass, a slightly critical comment—triggers a surge of anger or tears that feels completely out of proportion. You know it's too much. You can't stop it.
  • You're excited about a plan. When it falls through, you don't just feel disappointed—you crash into despair that takes hours to climb out of, even if the plan wasn't that important.

Commonly Confused With

Mood disorders

While emotional dysregulation is a feature of some mood disorders, in neurodivergent contexts it's an executive function issue rather than a mood disorder. The emotions are reactive to events, not free-floating.

Related Terms

Clinical Context

Emotional dysregulation is increasingly recognized as a core feature of ADHD, not just a secondary symptom. Barkley (2015) argues it should be included in diagnostic criteria.

Echolalia is the repetition of words, phrases, or sounds that a person has heard. It can be immediate (repeating something just said) or delayed (repeating a phrase from a movie, song, or past conversation hours, days, or years later). It's common in autistic people, particularly in childhood, and has historically been dismissed as meaningless or pathological. Research increasingly shows it's neither.

Echolalia serves multiple functions. It can be communicative (using a memorized phrase to express a need or feeling), regulatory (repeating sounds that feel soothing), processing-oriented (echoing speech to help comprehend it), or social (using shared scripts to connect with others). A child who answers "Do you want juice?" by repeating "Do you want juice?" may be saying yes—using the only language structure available to them in that moment.

Understanding echolalia as functional rather than meaningless changes how it's approached therapeutically. Instead of trying to eliminate it, effective support works with it—expanding the scripts, building on the phrases, and recognizing that echolalic speech is speech, even if it doesn't follow conventional patterns.

In Practice

  • Your child answers every question by repeating it back. Instead of correcting them, their speech therapist models the answer: "Do you want juice?" becomes "I want juice, yes!" Over time, the script expands into flexible communication.
  • You catch yourself repeating a phrase from a TV show under your breath at work. It's not random—the phrase perfectly captures a feeling you can't articulate in your own words. The borrowed language says what yours can't.

Commonly Confused With

Not understanding

Echolalia is often mistaken for a failure to comprehend. In many cases, the person understands perfectly—they're using repeated language as their way of responding, processing, or communicating within the limits of their available speech.

Related Terms

Clinical Context

Research by Prizant and Duchan (1981) established that echolalia serves communicative functions in autistic children, challenging the earlier view that it was non-functional. This finding has influenced modern speech-language therapy approaches.

Community Note

Many autistic adults use delayed echolalia as a rich communication tool—quoting movies, songs, or books to express complex emotions that their own words can't quite reach. It's not a deficit; it's a different relationship with language.

Energy accounting is the practice of deliberately tracking and managing your cognitive, emotional, and physical energy as a finite resource. It extends the metaphor of spoon theory into a more detailed framework: instead of just counting spoons, you're tracking what gives energy (deposits) and what costs energy (withdrawals) with enough granularity to plan your day around your actual capacity.

For neurodivergent people, energy accounting is essential because the costs are different from what neurotypical people experience. A social event that energizes one person might cost an autistic person hours of recovery. A task that a neurotypical colleague handles automatically might drain significant executive function capacity from someone with ADHD. Without conscious tracking, it's easy to overspend and crash.

Effective energy accounting includes identifying high-cost activities (masking, sensory environments, transitions, decision-making), low-cost or energy-positive activities (special interests, solitude, preferred sensory input), and planning the day so that withdrawals don't exceed deposits before essential tasks are complete.

In Practice

  • You know from experience that a two-hour meeting in a fluorescent-lit conference room costs you the rest of the afternoon. You schedule nothing after it—not because you're lazy, but because accurate energy accounting tells you the balance will be zero.
  • You turn down a Friday evening invitation because Saturday is a family event that will cost all your social energy. Your friends see two separate decisions; you see a single energy budget that can't cover both.

Related Terms

Community Note

Energy accounting is one of the most practical tools in the neurodivergent self-management toolkit. The shift from "I should be able to do everything" to "what can I actually afford today" isn't giving up—it's getting honest about capacity.

An external brain is any system outside your head that holds information your working memory can't retain reliably. For neurodivergent people, especially those with ADHD, the external brain isn't a nice-to-have productivity hack—it's a necessary cognitive prosthetic. It holds the thoughts, tasks, appointments, and intentions that your working memory would otherwise drop.

External brain systems can be analog (notebooks, whiteboards, sticky notes on the bathroom mirror), digital (note-taking apps, calendar apps, voice memos, automated reminders), or environmental (putting your keys in the same place every day, leaving your medication next to the coffee maker). The specific tools matter less than the principle: if it needs to be remembered, it needs to live somewhere outside your head.

The concept acknowledges something important: neurodivergent working memory isn't lazy—it's architecturally different. Instead of fighting the architecture, the external brain works with it. Your brain is freed up for the things it does well (creative thinking, problem-solving, pattern recognition) while the external system handles the things it doesn't (remembering, tracking, sequencing).

In Practice

  • Your phone has 47 recurring reminders, from "take medication" to "check if the laundry is done" to "drink water." A friend sees your notification screen and laughs. You don't explain that without those reminders, none of those things would happen.
  • You keep a massive notebook that functions as your external memory. If a thought isn't captured within seconds, it's gone. The notebook isn't optional—it's a load-bearing structure for your daily functioning.

The external brain concept helps reframe executive function support as a strength-based accommodation rather than a crutch. Neurotypical people use external brains too—they just call them "calendars" and don't feel shame about it.

Flat affect refers to a reduced outward expression of emotion: a neutral facial expression, monotone voice, limited gestures, and minimal visible emotional reactivity. In autistic people, flat affect is common and frequently misinterpreted. Observers assume the person doesn't feel anything, doesn't care, or isn't engaged—when the internal experience may be intensely emotional.

The disconnect between internal experience and external expression is the key issue. An autistic person watching a movie might feel deeply moved while their face shows nothing. They might be thrilled about a gift but respond with a flat "thanks." This isn't coldness or indifference—it's a difference in how emotions translate to visible expression. The emotional engine is running; the display panel just doesn't update at the same rate.

Flat affect can cause significant social difficulties because neurotypical communication relies heavily on reading facial expressions and vocal tone. When these signals are absent or muted, neurotypical observers fill in the gap with assumptions: they're bored, they don't like me, they're being rude. Understanding flat affect as an expressive difference rather than an emotional absence is crucial for accurate interpretation.

In Practice

  • Your partner gives you a birthday present you genuinely love. Your face doesn't change. You say "thank you" in a flat tone. They look hurt. Inside, you're delighted—but your body didn't get the memo to show it.
  • A colleague presents an idea in a meeting and you listen with genuine interest. Afterward, they ask your manager if you seemed disengaged. You weren't—your face just doesn't broadcast "interested" the way theirs does.

Commonly Confused With

Depression

Depression can cause flat affect through emotional numbing. Autistic flat affect involves full emotional experience with reduced outward expression. The difference matters for treatment—emotional expression coaching, not antidepressants, addresses an expressive difference.

Clinical Context

Flat or reduced affect is noted in the DSM-5 under ASD as potential differences in emotional expression. Research increasingly distinguishes between emotional experience (which may be intact or heightened) and emotional expression (which may be atypical) in autistic individuals.

Hyperfocus is the ability to become so deeply absorbed in a task that everything else fades: time, hunger, other responsibilities, even physical discomfort. It's common in ADHD and autism, and it contradicts the popular misconception that these conditions are only about distraction.

The catch is that hyperfocus isn't voluntary. You can't choose when it activates or what it locks onto. It tends to engage for tasks that are novel, interesting, urgent, or emotionally stimulating—and disengage abruptly when the dopamine reward dries up. This means you might hyperfocus on reorganizing your bookshelf for five hours while ignoring the work deadline that's actually urgent.

When hyperfocus aligns with useful goals, it can produce remarkable output. Many neurodivergent people describe their greatest accomplishments as products of hyperfocus. But it can also lead to neglected relationships, missed meals, disrupted sleep, and burnout when it goes unchecked.

In Practice

  • You start researching a new topic at 8 PM "for just a few minutes." When you next look up, it's 2 AM and you've opened 47 browser tabs.
  • You're working on a creative project and your partner has to physically tap your shoulder to get your attention—you genuinely didn't hear them calling your name three times.

Commonly Confused With

Flow state

Flow is a voluntary state of optimal performance. Hyperfocus is often involuntary, harder to exit, and doesn't always align with productive goals. Flow feels good throughout; hyperfocus can feel compulsive and leave you drained.

Community Note

Many neurodivergent people have a complicated relationship with hyperfocus. It's responsible for both their best work and their worst burnout. Learning to "ride" hyperfocus—channeling it without being controlled by it—is a common goal.

Habit stacking is the practice of linking a new behavior to an existing one, using the established habit as a trigger: "After I pour my morning coffee, I take my medication." "After I brush my teeth, I do two minutes of stretching." The existing habit provides the cue that the new behavior needs to start.

For ADHD brains, habit stacking is one of the most effective behavior-change strategies because it bypasses the task initiation problem. Starting a brand-new behavior from nothing requires executive function that may not be available. But piggybacking on a behavior that's already automatic—one that doesn't require conscious activation—means the new behavior gets pulled along for the ride.

The key is choosing anchor habits that are genuinely automatic and consistent. If the anchor habit is itself unreliable (like "after I check my planner"), the stack will collapse. The strongest anchors are physical routines that happen in the same place, at the same time, every day: brushing teeth, making coffee, arriving at your desk, eating lunch.

In Practice

  • You could never remember to take your vitamins. You tried alarms, sticky notes, and pill organizers. Then you put the bottle next to the coffee maker. Now you take them every morning—not because you remember, but because making coffee is automatic and the vitamins are in the way.
  • You want to start journaling but can't manage to "just do it" in the morning. You stack it onto brushing your teeth: notebook and pen live on the bathroom counter, and you write three sentences while your teeth air-dry. The stack holds because the anchor is bulletproof.

Related Terms

Community Note

Habit stacking was popularized by James Clear in Atomic Habits, but ADHD communities have refined it with an important caveat: keep the stacked behavior tiny. An ADHD brain will abandon a stack that feels too big. "Take one vitamin" stacks better than "complete a 20-minute wellness routine."

The interest-based nervous system is a framework popularized by Dr. William Dodson to describe how ADHD brains allocate attention and motivation. Most people operate on an importance-based nervous system: they can generate motivation for tasks because those tasks are important, expected, or rewarded. ADHD brains operate differently—they're driven by interest, challenge, novelty, urgency, and passion.

This explains one of the most frustrating paradoxes of ADHD: the ability to spend eight hours on a fascinating hobby while being unable to spend 15 minutes on a crucial task. It's not a choice or a character flaw. The ADHD brain literally cannot generate motivation through importance alone—it needs one of those other activation triggers.

Understanding this framework is transformative because it replaces moral judgment with strategic thinking. Instead of asking "why can't I make myself do this?" you can ask "how can I make this interesting, urgent, or novel enough to engage my brain?"

In Practice

  • You can't start writing a report until the deadline is tomorrow (urgency). But if someone challenged you to write it in under an hour, you'd suddenly be able to do it (challenge + novelty).
  • You understand that paying your taxes is important. Your brain does not care. But if you gamify the process or do it alongside a friend, suddenly you can engage with it—because your nervous system responds to interest, not importance.

Community Note

This concept resonates deeply with many ADHD adults because it replaces decades of "you're not trying hard enough" with "your brain has a different activation system." It's not about effort—it's about neurological fit.

Infodumping is the act of sharing a large amount of information about a topic you know deeply—often a special interest—in a single, extended burst. It's common in autistic and ADHD experience, and it's driven by genuine excitement, expertise, and the desire to share something meaningful.

From the neurodivergent person's perspective, infodumping feels like finally getting to talk about something you care about with someone who (hopefully) wants to listen. It's a form of connection and self-expression. The information isn't random—it's carefully organized in the person's mind, and sharing it is an act of trust and enthusiasm.

From a neurotypical perspective, infodumping can feel overwhelming or one-sided, which creates social friction. This mismatch isn't because the neurodivergent person doesn't care about reciprocity—it's because their communication style favors depth over back-and-forth exchange. Many autistic people describe infodumping as one of the most natural ways they connect, and having it received warmly is deeply meaningful.

In Practice

  • Your friend mentions they saw a bird in their yard. Twenty minutes later, you've explained the bird's migration patterns, nesting habits, population trends, and the ecological factors threatening its habitat. You look up and realize their eyes have glazed over.
  • Someone asks a casual question about a topic that happens to be your special interest. You answer with a five-minute explanation when they expected two sentences. You're not showing off—you genuinely can't tell where "enough information" is.

Related Terms

Community Note

The neurodivergent community has reclaimed infodumping as a positive term. "Being someone's safe person to infodump to" is considered a meaningful form of intimacy. Many neurodivergent couples describe mutual infodumping as one of the best parts of their relationship.

Interoception is your body's internal sensing system. It's how you know you're hungry, thirsty, too hot, in pain, need the bathroom, or are becoming emotionally activated. Most people take these signals for granted—hunger builds gradually, you notice, you eat. For many neurodivergent people, interoceptive signals are muted, delayed, or confusingly intense.

Poor interoception can look like forgetting to eat until you're shaking, not noticing you need the bathroom until it's urgent, wearing a coat in summer because you can't gauge your body temperature, or not realizing you're stressed until you're already in a meltdown. The signals aren't absent—they're just harder to detect and interpret.

This has ripple effects across daily life. If you can't reliably sense hunger, you eat erratically. If you can't feel fatigue building, you crash instead of resting. If you can't identify the early signs of emotional overwhelm, you skip the window where coping strategies would have helped. Understanding interoception is often a missing piece for people who've struggled with self-regulation their whole lives.

In Practice

  • You've been working for six hours and suddenly realize you're starving, freezing, and desperately need the bathroom—all at once. None of those signals registered until they became emergencies.
  • Someone asks if you're anxious and you say no. Ten minutes later you notice your heart is racing, your jaw is clenched, and your stomach is in knots. Your body knew. You just couldn't read it.

Irlen syndrome (also called scotopic sensitivity syndrome or visual stress) is a condition where the brain has difficulty processing specific wavelengths of light. This can make reading physically uncomfortable: text may appear to move, blur, double, or wash out under certain lighting conditions. White pages can seem blindingly bright, and fluorescent lighting can be particularly unbearable.

Irlen syndrome is not an eye problem—standard vision tests come back normal. It's a brain-based processing issue, which is why it often goes undiagnosed for years. People who have it develop coping strategies without realizing what they're compensating for: tilting pages, reading in dim light, using a finger to track lines, or simply avoiding reading altogether.

The condition frequently co-occurs with dyslexia, ADHD, and autism, which complicates diagnosis further. A child who struggles to read might be identified as dyslexic when the real issue—or an additional issue—is that the page itself is causing visual distress. Colored overlays or tinted lenses (Irlen lenses) can provide significant relief for some people, though the evidence base remains debated in clinical circles.

In Practice

  • You've always hated reading under fluorescent lights but couldn't explain why. When someone puts a colored overlay on the page, the text suddenly stops swimming and you read a full paragraph without losing your place for the first time.
  • You assumed everyone saw text "vibrate" slightly on white paper. Learning that this isn't universal—and that there's a name for it—reframes years of reading avoidance as a sensory issue, not laziness.

Related Terms

Clinical Context

Irlen syndrome was identified by Helen Irlen in the 1980s. While colored overlays and tinted lenses are widely used and many individuals report significant benefit, the condition remains controversial in mainstream optometry and lacks consensus diagnostic criteria.

Community Note

Many people discover Irlen syndrome through other neurodivergent communities—someone with dyslexia or autism mentions colored overlays and it clicks. The relief of finding a simple intervention after years of struggle is often described as life-changing.

Identity-first language places the condition before the person: "autistic person," "Deaf person," "disabled person." Person-first language does the opposite: "person with autism," "person with a hearing impairment," "person with a disability." The debate between these two approaches is one of the most visible conversations in disability and neurodivergent communities.

Most autistic self-advocates prefer identity-first language. The reasoning: autism isn't something you carry around like a bag—it's woven into how you think, perceive, and experience the world. Saying "person with autism" implies autism is separable from the person, something that could theoretically be removed. Saying "autistic person" acknowledges that autism is a fundamental part of who someone is, not an add-on.

This preference isn't universal. Some people, particularly those with acquired conditions or those who don't want a diagnosis to define them, prefer person-first language. Many ADHD communities use both interchangeably. The most respectful approach is to ask individuals their preference—and when speaking about a community as a whole, to follow that community's majority preference.

In Practice

  • A well-meaning colleague insists on saying "person with autism" because they were taught it's more respectful. You explain that most autistic adults actually prefer "autistic"—and that respecting the community's own language choice is the more respectful move.
  • You're writing a school policy and aren't sure which language to use. You check the Autistic Self Advocacy Network, which uses identity-first language, and follow their lead for autism-related references while using person-first for other conditions where that's the community preference.

Related Terms

Community Note

The identity-first preference is strong in autistic communities but less settled elsewhere. The key principle isn't which format is universally correct—it's that affected communities get to choose their own language, and outsiders should follow their lead.

Impostor syndrome is the feeling that you don't deserve your achievements, that you've fooled everyone into thinking you're competent, and that you'll be "found out" at any moment. While it affects many people, it has a particular intensity and flavor in neurodivergent experience.

For neurodivergent people, impostor syndrome often runs in two directions simultaneously. Before diagnosis: "Maybe I'm just lazy and everyone else is right that I should try harder." After diagnosis: "Maybe I'm not really neurodivergent—maybe I'm just making excuses." Both versions deny the person's reality, and both are reinforced by a world that doesn't understand neurological variation.

The post-diagnosis version is especially cruel. You finally have a framework that explains decades of struggle, and your brain immediately starts arguing against it. You weren't "really" struggling—you finished college, held a job, maintained relationships. Never mind that each of those required three times the effort they should have. Impostor syndrome takes the very evidence of your compensation and uses it against you.

In Practice

  • You get your ADHD diagnosis and feel relief for about a week. Then the doubt creeps in: "What if the psychiatrist was wrong? What if I just need to try harder? What if I'm taking a diagnosis away from someone who really needs it?"
  • You succeed at work but attribute it entirely to luck, timing, or your coping mechanisms. The idea that you might actually be good at your job—and neurodivergent—feels like a contradiction your brain can't hold.

Community Note

In neurodivergent communities, impostor syndrome is so common it's almost a rite of passage. The shared recognition—"you feel like a fraud too?"—is itself therapeutic. It turns a private shame into a collective pattern with a structural explanation.

In the United States, two main legal frameworks provide educational support for students with disabilities: Individualized Education Programs (IEPs) and 504 Plans. Both require schools to provide accommodations, but they differ in scope and legal basis.

An IEP is developed under the Individuals with Disabilities Education Act (IDEA). It's a detailed plan that includes specific learning goals, specialized instruction, related services (speech therapy, occupational therapy, counseling), and measurable benchmarks. IEPs are for students who need specially designed instruction to access education. The process involves formal evaluation, a team meeting, and ongoing review.

A 504 Plan is developed under Section 504 of the Rehabilitation Act. It provides accommodations—like extended test time, preferential seating, or assistive technology—but doesn't include specialized instruction or individual learning goals. It's for students who can learn in a general education setting with the right supports in place.

For neurodivergent students, either plan can be appropriate depending on the level of support needed. Many students with ADHD, for instance, receive 504 Plans with accommodations like movement breaks and extended time, while students with more significant learning differences might need the specialized instruction an IEP provides.

In Practice

  • Your child's teacher says they're "doing fine" in class. You know they're spending three hours on homework that should take thirty minutes. Getting a 504 Plan means the school finally acknowledges that "doing fine" is costing your child their entire evening.
  • A student with an IEP transitions to college and discovers that IEPs don't transfer to higher education. They need to navigate a completely different system of disability services, often without guidance.

Related Terms

Clinical Context

IEPs are governed by IDEA (Individuals with Disabilities Education Act), which requires a free appropriate public education (FAPE) for eligible students. 504 Plans are governed by Section 504 of the Rehabilitation Act of 1973, a civil rights law prohibiting disability discrimination.

Community Note

Navigating the IEP/504 process is often described by parents as a second job. The system is supposed to be collaborative, but many families—particularly those without resources to hire advocates—find it adversarial. Knowing your rights and the specific language of the law makes a significant difference.

Impulse control is the brain's ability to insert a pause between an impulse and an action—long enough to evaluate whether the action is a good idea. For people with ADHD, this pause is shorter, less reliable, and sometimes absent entirely. The impulse and the action can happen almost simultaneously.

This shows up across every domain of life: blurting out answers before the question is finished, interrupting conversations, making impulsive purchases, saying things you immediately regret, starting new projects before finishing old ones, and acting on emotions before you've had time to evaluate them. The common thread is speed—the action happens before the evaluation process can engage.

Impaired impulse control is a neurological difference, not a character flaw. Research shows that it's connected to differences in the prefrontal cortex (responsible for executive function) and dopamine regulation (which affects reward evaluation). This is why ADHD medication often dramatically improves impulse control—it's addressing the neurology, not the person's willpower.

In Practice

  • You're in a meeting and a thought pops into your head. Before you can evaluate whether it's relevant, appropriate, or well-timed, you've already said it out loud. The room goes quiet. You wish you could rewind.
  • You open your phone to check the weather and 45 minutes later you've purchased a kitchen gadget, signed up for a class you'll never attend, and can't remember what you originally picked up your phone to do.

Commonly Confused With

Not caring

People with impulse control differences often care intensely about the consequences of their actions—they feel the regret immediately after. The issue isn't caring; it's that the evaluation happens after the action instead of before it.

Related Terms

Clinical Context

Impaired impulse control is one of the core symptoms of ADHD in the DSM-5, categorized under the hyperactive-impulsive presentation. Barkley (1997) proposed that behavioral inhibition deficits are the central feature of ADHD.

Internal hyperactivity is the form of ADHD hyperactivity that doesn't show on the outside. It's a constant mental restlessness: racing thoughts, a busy inner monologue, difficulty slowing your brain down, and a persistent feeling of being revved up even when you're physically still. It's the reason many people with ADHD—especially women and adults—are never identified, because they don't match the stereotype of bouncing off the walls.

In childhood, ADHD hyperactivity is often visible: running, climbing, fidgeting, inability to sit still. In adulthood, the external hyperactivity often shifts inward. The body may be still, but the mind is running at full speed. This can look like an inability to relax, difficulty falling asleep because your brain won't quiet down, jumping from thought to thought mid-conversation, and a chronic sense that you should be doing something even when you're ostensibly resting.

Internal hyperactivity is exhausting because there's no off switch. You can't step away from your own mind. And because it's invisible, others may not understand why you seem so tired when you've "been sitting down all day." The effort of managing a brain that won't idle is real work—it just happens where nobody can see it.

In Practice

  • You lie in bed trying to sleep and your brain presents you with an unsolicited highlight reel of everything that happened today, everything you need to do tomorrow, a song you heard in 2014, and a creative idea you'll forget by morning. Your body is exhausted. Your brain is hosting a festival.
  • Someone asks why you seem tired after a "relaxing" weekend at home. You don't know how to explain that your brain didn't stop for a single waking moment—relaxing and resting aren't the same thing when your mind never idles.

Related Terms

Clinical Context

The DSM-5 describes hyperactivity in adults as "often feeling restless" rather than the childhood presentation of running and climbing. Barkley (2015) argues that internal restlessness is the adult expression of the same neurological hyperactivity seen in childhood.

Community Note

Internal hyperactivity is one of the biggest reasons ADHD is missed in adults, especially women. When clinicians look for the stereotypical "bouncing off the walls" and don't see it, they dismiss ADHD—not realizing the bouncing is happening entirely inside.

Job crafting is the practice of proactively modifying aspects of your job to create a better fit between your work and your abilities. It was originally described by researchers Wrzesniewski and Dutton as a way employees reshape their roles in three dimensions: task crafting (changing what you do), relational crafting (changing who you work with), and cognitive crafting (changing how you think about your work).

For neurodivergent people, job crafting is often a survival skill practiced long before they know the term. You volunteer for the detail-oriented projects because your brain is built for them, and steer away from the networking events that drain you. You negotiate to do your deep work in the mornings when your medication is most effective. You find a desk in the quiet corner without asking permission.

The difference between informal adaptation and intentional job crafting is awareness and agency. When you understand your neurodivergent profile—where you excel, where you struggle, what conditions support your best work—you can make strategic choices about how to shape your role rather than just reacting to whatever causes the least pain.

In Practice

  • You realize that client calls drain you for hours afterward, but written communication is effortless. You propose handling client updates via email and let a colleague take the calls. Both of you end up more productive.
  • Your job description says "manages social media," but you've quietly shifted the role toward analytics and content strategy because those tasks engage your pattern-recognition strengths instead of draining your social energy.

Related Terms

Clinical Context

Wrzesniewski and Dutton (2001) defined job crafting as the process by which employees redefine and reimagine their work. Research suggests it improves job satisfaction, engagement, and performance—particularly for employees whose needs don't fit standardized role designs.

Late diagnosis refers to being identified as neurodivergent (ADHD, autistic, dyslexic, etc.) in adulthood rather than childhood. This is increasingly common as understanding of neurodivergence expands beyond the stereotypes that dominated earlier diagnostic criteria—stereotypes that were largely based on white boys.

Late diagnosis is especially common in women, people of color, people with high IQs, and anyone who developed effective masking strategies early in life. Many late-diagnosed adults spent years with alternative explanations for their struggles: anxiety, depression, burnout, personality disorders, or simply "not trying hard enough." The diagnosis often reframes an entire life story.

The emotional experience of late diagnosis is complex. There's typically relief ("so that's why everything has been so hard"), grief ("I spent 30 years blaming myself for something that had a name"), anger ("why didn't anyone catch this?"), and sometimes identity disruption ("who am I if I'm not the person I thought I was?"). Processing these feelings is a significant part of post-diagnosis life.

In Practice

  • At 38, you get an ADHD diagnosis. Suddenly, every report card that said "smart but not applying herself," every job you left after six months, every friendship that faded because you forgot to reply—all of it clicks into a pattern you couldn't see before.
  • You tell your family about your autism diagnosis and they say "but you're so normal." You realize that "normal" was a performance you'd been giving for their benefit your entire life.

Related Terms

Community Note

Late-diagnosed adults often become passionate advocates precisely because they remember what it was like to not know. The phrase "I'm not late to the diagnosis—the diagnosis was late to me" captures a common sentiment.

References

Learned helplessness is a psychological state in which a person stops trying because past experience has taught them that their efforts don't lead to success. The concept was first described by Martin Seligman in the 1960s through animal research, but it maps powerfully onto the neurodivergent experience.

When you've spent years trying strategies that work for neurotypical brains and failing, your brain draws a logical conclusion: effort doesn't work. You've tried harder, used willpower, set reminders, made promises, and still missed deadlines, forgotten commitments, and let people down. At some point, the nervous system stops investing energy in attempts that have a track record of failure. This isn't laziness—it's a rational response to repeated negative outcomes.

Breaking learned helplessness in neurodivergent people requires more than motivation or encouragement. It requires changing the conditions so that effort actually works. This usually means neurodivergent-specific strategies, accommodations, and environments where success is possible—proving to the nervous system that outcomes can change when the approach changes.

In Practice

  • Your teacher told you to use a planner. You tried. It didn't work. They told you to try harder. You did. It still didn't work. After enough rounds of this, you stopped trying organizational strategies altogether—because in your experience, they never help.
  • You don't apply for the promotion because you "know" you'll fail the interview. You have evidence: you've failed before. What you don't have is the understanding that the interview format itself was the barrier, not your competence.

Clinical Context

Seligman's learned helplessness theory (1972) has been extended to explain depression and motivational deficits. In neurodivergent contexts, it helps explain why traditional interventions often fail—they attempt to increase effort without changing the conditions that made effort futile.

Literal thinking is the tendency to process language at face value, interpreting words and phrases according to their direct meaning rather than their implied or figurative meaning. When someone says "I'll be there in a second," a literal thinker may genuinely expect them in one second. When someone says "break a leg," the literal response might be confusion or concern.

This is a common autistic trait, and it's not about intelligence or language ability. Many autistic people have extensive vocabularies and sophisticated understanding of language—the difference is in the default processing mode. Where neurotypical brains automatically scan for subtext, sarcasm, idiom, and implied meaning, autistic brains often process the surface meaning first and require conscious effort to access the layer underneath.

Literal thinking can be both a challenge and a strength. It causes miscommunication when figurative language is assumed to be understood. But it also produces clarity, precision, and an ability to notice when language is being used imprecisely or deceptively. Many autistic people develop a secondary skill in figurative language through study and experience—they learn the idioms, master sarcasm detection, and build a mental database of non-literal phrases. But the default remains literal, and energy is required to override it.

In Practice

  • Your boss says "let's table this discussion." You look for a table. Or you understand the idiom but it takes an extra beat of processing—a delay that's invisible to everyone else but costs you cognitive energy across dozens of such phrases every day.
  • Your friend says "I could eat a horse" and you don't think they literally plan to eat a horse—but your brain briefly considers the image before catching up. The figurative meaning arrives, just on a slight delay.

Related Terms

Community Note

Many autistic people have a complicated relationship with literal thinking—it causes enough miscommunication to be frustrating, but it also produces a directness and precision in their own speech that they value. The goal isn't to "fix" literal thinking; it's to build bridges between communication styles.

Masking (also called camouflaging) is the practice of hiding or suppressing neurodivergent traits—stimming, communication differences, sensory needs, emotional responses—and replacing them with learned "normal" behaviors. It's common in both autism and ADHD, and it's especially prevalent in women, people of color, and anyone who's been socially punished for being different.

Masking can be conscious (deliberately suppressing a stim in a meeting) or unconscious (automatically mirroring the social behavior of people around you without realizing you're doing it). It often develops in childhood as a survival strategy and becomes so automatic that many people don't realize they're doing it until they learn about the concept.

The cost of masking is real and cumulative. It drains cognitive and emotional resources, contributes to autistic burnout, can delay diagnosis by decades, and creates a painful gap between who you are and who people think you are. Unmasking—learning to drop the performance—is a common focus of post-diagnosis work, but it's not simple. Social consequences are real, and letting go of lifelong habits takes time and safety.

In Practice

  • You spend a work meeting carefully controlling your facial expressions, monitoring your tone of voice, and timing your responses—then collapse in exhaustion the moment you get home.
  • A friend says "you don't seem autistic" and you realize that's because you've been performing neurotypicality so effectively that your real self is invisible.

Commonly Confused With

Code-switching

Code-switching involves adjusting language or behavior across different social contexts and is common across many groups. Masking is more specific to neurodivergence—it involves suppressing core neurological traits and can cause significant psychological harm over time.

A meltdown is an involuntary loss of behavioral control triggered by overwhelming input that exceeds the nervous system's capacity to cope. It can look like crying, screaming, hitting, throwing things, or other intense external expressions. From the outside it may resemble a tantrum, but the internal experience is fundamentally different.

The critical distinction: a tantrum is goal-directed behavior (a child screaming because they want candy). A meltdown is a system failure (a person's nervous system has been pushed past its breaking point and the body's stress response has taken over). No one chooses to have a meltdown, and they can't be stopped through willpower once they start.

Meltdowns are preceded by a buildup of stress, sensory input, social demands, or cognitive load—often over hours or days. The visible meltdown is just the breaking point. Many people feel intense shame afterward, even though the meltdown was no more voluntary than a sneeze. Recovery can take hours to days and often involves a period of reduced capacity.

In Practice

  • After a long day of noise, social demands, and disrupted routine, a small thing—a dropped plate, a schedule change—tips you over the edge. The reaction looks "crazy" to observers, but it's the culmination of eight hours of accumulating overload.
  • You feel a meltdown building during a family event: the noise, the lights, the unpredictable social dynamics. You try to leave before it hits, but someone stops you to chat. The meltdown arrives in the car, and you spend 20 minutes crying before you can drive home.

Commonly Confused With

Tantrum

Tantrums are intentional and stop when the desired outcome is achieved (or when no one is watching). Meltdowns are involuntary, often happen regardless of audience, and the person having one would stop if they could. The distinction matters because the appropriate response is completely different—comfort and space, not discipline.

Community Note

Many autistic adults say they experience meltdowns differently as they age—less external, more internal—which can make them harder for others to recognize. An adult meltdown might look like going silent in a meeting rather than screaming, but the internal distress is just as intense.

Monotropism is a theory developed by Dinah Murray, Wenn Lawson, and Mike Lesser that offers an alternative framework for understanding autism. The core idea: attention can be distributed broadly across many things (polytropism) or focused intensely on fewer things (monotropism). Autistic brains tend toward monotropism—deep, narrow attention tunnels.

This single concept explains many autistic traits without framing them as deficits. Special interests? Deep attention on a single topic. Difficulty with transitions? Attention is invested heavily and redirecting it is costly. Sensory overload? When attention is focused, unexpected sensory input feels intrusive. Social difficulties? Social interaction requires splitting attention across many channels simultaneously—something monotropic processing makes harder.

Many autistic people consider monotropism the most accurate description of their internal experience. It reframes autism not as a collection of deficits but as a fundamentally different attention style—one that produces both remarkable depth and genuine challenges in a world designed for polytropism.

In Practice

  • When you're working on something, you can't "just" switch to a new task. Your attention is like a river flowing in one channel—diverting it requires building a new channel, which takes time and energy that's invisible to people whose attention distributes more easily.
  • You can spend six hours researching a topic and forget to eat, drink, or use the bathroom. Your attention doesn't distribute to those needs because it's fully invested in one channel.

Community Note

Monotropism has become increasingly popular in autistic communities as a framework that "finally makes sense." Many prefer it to deficit-based models because it describes the same traits from a neutral, explanatory perspective rather than a pathological one.

Motor planning (also called praxis) is the cognitive process of figuring out how to move your body to accomplish a task. It involves three stages: ideation (knowing what you want to do), planning (figuring out the sequence of movements), and execution (actually doing it). When any stage is disrupted, movement becomes unreliable.

Motor planning difficulties are a core feature of dyspraxia (developmental coordination disorder) and are common in autism and ADHD. They can affect both gross motor skills (running, climbing, catching a ball) and fine motor skills (handwriting, buttoning shirts, using utensils). The movements themselves aren't impossible—the brain just needs more time and conscious effort to organize them.

What makes motor planning difficulties frustrating is their inconsistency. You might tie your shoes perfectly one morning and fumble with the laces the next. The skill is there, but accessing it on demand requires a level of conscious attention that most people never need to apply to automatic movements. This inconsistency is often misread as carelessness.

In Practice

  • You know how to pour water from a pitcher, but your hand tilts too fast and it spills. It's not that you lack strength or coordination—your brain sent the "pour" instruction without calibrating the speed. It happens with enough regularity that you've started avoiding pouring in front of others.
  • Learning a new exercise at the gym takes you three times as many repetitions as the person next to you. Your body understands each individual movement, but stringing them into a sequence requires intense concentration.

Related Terms

Clinical Context

Motor planning difficulties are assessed through standardized tests of praxis. They are a defining feature of developmental coordination disorder (DCD/dyspraxia) and are increasingly recognized in autism research as a distinct motor processing difference.

Math anxiety is a specific form of performance anxiety triggered by mathematical tasks. It's not just disliking math—it's a stress response that can include racing heart, sweaty palms, mental blanking, and avoidance behavior. For some people, the anxiety is so intense that it actively interferes with their ability to do math they actually understand.

The relationship between math anxiety and dyscalculia is tangled. Math anxiety can develop as a result of dyscalculia (years of failing at math naturally produces fear of it), but it can also develop independently in people without any underlying numerical processing difference. And once present, math anxiety produces symptoms that look like dyscalculia—working memory gets consumed by anxiety, leaving less capacity for actual calculation. This makes accurate diagnosis genuinely difficult.

The instructional environment plays a huge role. Timed tests, public board work, and "math facts" drills are particularly anxiety-producing for students who process numbers differently. Many adults with math anxiety can trace it back to a specific classroom experience where they were humiliated or singled out for not being fast enough.

In Practice

  • You freeze at a cash register trying to count change, even though you could do it calmly at home. The pressure of someone waiting turns a simple calculation into a wall of panic.
  • Your child loves puzzles and logic games but cries before math class. The problem isn't their ability—it's the timed multiplication quizzes that make their mind go blank every Friday.

Related Terms

Clinical Context

Ashcraft and Krause (2007) demonstrated that math anxiety reduces available working memory during mathematical tasks, producing performance deficits independent of actual math ability. This has significant implications for assessment and diagnosis.

Community Note

Many adults discover their "hatred of math" was actually anxiety when they encounter math in a low-pressure context and realize they can do it. The problem was never the math—it was the conditions under which they were expected to perform it.

Misophonia literally means "hatred of sound," but it's more accurately described as a strong, involuntary emotional and physiological response to specific trigger sounds. Common triggers include chewing, lip-smacking, pen-clicking, sniffling, keyboard typing, and repetitive tapping. The response isn't proportional to the sound's volume—a quiet chew can be as triggering as a loud one.

What distinguishes misophonia from simple annoyance is the intensity and involuntary nature of the reaction. Trigger sounds produce an immediate fight-or-flight response: rage, panic, disgust, or an overwhelming need to escape. The person isn't choosing to be upset—their nervous system is treating the sound as a threat. Heart rate increases, muscles tense, and the person may experience a surge of adrenaline that takes minutes or hours to subside.

Misophonia frequently co-occurs with autism, ADHD, and anxiety, which makes sense given the shared sensory processing differences. It's increasingly recognized as a distinct neurological condition rather than a psychological quirk, with research pointing to differences in how the brain's salience network responds to specific auditory patterns.

In Practice

  • Your partner eats an apple and you have to leave the room. You know it's irrational. You know they're not doing anything wrong. But the sound produces a wave of rage so intense that staying feels physically dangerous—not to them, but to your nervous system.
  • You wear earbuds in every meeting because the sound of someone clicking their pen triggers a visceral response that makes it impossible to concentrate on anything else. You've never told anyone why—you just seem like someone who likes music.

Related Terms

Clinical Context

Jastreboff and Jastreboff (2001) first proposed misophonia as a clinical condition. Recent neuroimaging studies (Kumar et al., 2017) have identified differences in anterior insular cortex activity in people with misophonia, supporting a neurological rather than purely psychological explanation.

Community Note

Misophonia can strain relationships because trigger sounds are often produced by the people closest to you—family members, partners, coworkers. The shame of "hating" a sound your loved one makes adds an emotional layer on top of the sensory one.

Motivation deficit in ADHD isn't about not caring or not wanting to act. It's about the neurological gap between intention and activation. You want to do the thing. You know it matters. You can see exactly what needs to happen. But the internal engine that converts "I should" into "I am" doesn't fire reliably.

This happens because motivation is largely driven by dopamine, and ADHD brains have differences in dopamine regulation. Neurotypical motivation works like a sliding scale: the more important something is, the more motivated you feel. ADHD motivation is more binary: either the task generates enough interest, novelty, urgency, or emotional charge to activate the system, or it doesn't—regardless of how important it is. This is why you can spend hours on a passion project but can't start a tax return that's due tomorrow.

Understanding this as neurological rather than moral changes everything. It means the solution isn't "try harder" (which treats motivation as a character issue) but "change the conditions" (which treats motivation as a brain chemistry issue). Adding urgency, novelty, accountability, or interest to a task isn't cheating—it's engineering the dopamine conditions your brain needs to engage.

In Practice

  • You have a report due Friday. You care about your job. You understand the consequences. You sit at your desk. And nothing happens. The instruction from your brain to your hands to start typing simply doesn't arrive.
  • You notice that you can only do your taxes when the deadline is hours away—the urgency finally provides the activation energy your brain needs. You're not procrastinating by choice; you're waiting for the neurological conditions that make action possible.

Commonly Confused With

Laziness

Laziness is choosing comfort over effort when you have the ability to act. Motivation deficit is the inability to generate the neurological drive to act, even when you desperately want to. The person with a motivation deficit is usually in more distress about not acting than anyone observing them.

Research on dopamine dysregulation in ADHD supports the understanding of motivation deficits as neurological rather than volitional. Volkow et al. (2009) demonstrated reduced dopamine receptor and transporter availability in the reward pathways of adults with ADHD.

Neurodiversity is the idea that neurological differences—ADHD, autism, dyslexia, Tourette syndrome, and others—are a normal part of human variation rather than defects to be fixed. The term was developed by Australian sociologist Judy Singer in her 1998 thesis and published in 1999, drawing a parallel to biodiversity: just as ecosystems thrive through variation, so does humanity.

The neurodiversity framework doesn't deny that neurological differences can be disabling. It challenges the assumption that there's one correct way for a brain to work and that everyone who deviates from that standard is broken. This matters because the "broken brain" narrative shapes everything from how diagnoses are delivered to how support systems are designed—and it often causes more harm than the conditions themselves.

Neurodiversity is a fact about populations, not about individuals. You don't "have neurodiversity" the way you might have ADHD. The term describes the full range of neurological variation within a group. The related terms "neurodivergent" and "neurotypical" describe individuals.

In Practice

  • A school redesigns its classrooms with flexible seating, quiet zones, and movement breaks—not as special accommodations for "those kids," but as standard practice because brains learn differently.
  • You stop introducing your diagnosis as something you "suffer from" and start describing it as how your brain works. The shift feels small, but it changes the entire conversation.

Commonly Confused With

Neurodivergent

Neurodiversity describes the range of variation across a population. Neurodivergent describes an individual whose brain diverges from the dominant norm. You don't "have neurodiversity"—you're part of it.

Related Terms

Clinical Context

While neurodiversity is not a clinical term, it has influenced research and policy. The neurodiversity paradigm is increasingly referenced in academic literature as a framework for understanding developmental conditions.

Community Note

Judy Singer has described developing the term as an intentional parallel to biodiversity. The neurodiversity movement has grown far beyond academia into a civil rights framework embraced by self-advocates worldwide.

Neurodivergent means your neurology diverges from the dominant societal standard. The term was coined by Kassiane Asasumasu, a multiply-neurodivergent activist, as a way to describe individuals within the neurodiversity framework. Where "neurodiversity" describes the fact that brains vary across populations, "neurodivergent" describes a specific person whose brain works differently from the norm.

The term is intentionally broad. It can include people with ADHD, autism, dyslexia, dyspraxia, Tourette syndrome, OCD, epilepsy, and other neurological variations. Some people also include acquired neurological differences like traumatic brain injury. There's no official checklist—the term is a self-identification tool, not a clinical diagnosis.

What makes the term useful is its neutrality. It describes difference without implying deficit. Saying "I'm neurodivergent" doesn't carry the same weight as listing diagnoses, and for many people it provides a way to talk about their experiences without pathologizing language.

In Practice

  • You're filling out a workplace survey and see "neurodivergent" as an option. You check it without having to decide which of your three diagnoses to disclose.
  • A friend says "I think I might be neurodivergent." They're not sure which label fits, but they know their brain doesn't work the way most people's seems to. The word gives them a starting point.

Related Terms

Community Note

Kassiane Asasumasu coined "neurodivergent" to fill a gap—there was a word for the concept (neurodiversity) but not for the individual. The term spread through activist communities and is now widely used in clinical, educational, and workplace settings.

Neurotypical describes someone whose brain functions in ways that society considers standard or expected. The term exists as a counterpart to "neurodivergent," and its purpose isn't to create an us-vs-them divide—it's to name a default that usually goes unnamed.

Before "neurotypical" existed, the only options were "normal" and "not normal." That framing puts all the weight on the neurodivergent person to explain their difference. Having a word for the majority experience makes it possible to talk about neurological differences without implying that one side is the standard and the other is the deviation.

The term originated in autistic communities in the late 1990s, initially sometimes used sarcastically ("neurotypical syndrome"), but has settled into a genuinely useful piece of vocabulary. It's not an insult—it's a description. And it's important because it makes visible the fact that "typical" is just one way of being, not the only way.

In Practice

  • You explain to your neurotypical partner why you need an hour alone after a social event. Having the word "neurotypical" helps frame it as a difference in wiring, not a personal rejection.
  • A teacher describes a lesson plan as designed "for neurotypical learners." Naming it this way makes it clear that other learners might need something different—rather than treating the default as universal.

Related Terms

Community Note

Some people bristle at the term, hearing it as dismissive. But most neurodivergent communities use it matter-of-factly. The point isn't to minimize neurotypical experience—it's to stop treating it as the only valid one.

Number sense is the innate ability to perceive and understand quantities without counting. It's what tells you that a group of seven objects is "more" than a group of three, that 100 is closer to 90 than to 50, and that dividing a pizza among four people means smaller slices than dividing it among two. Most people develop this sense naturally in early childhood; for people with dyscalculia, it doesn't develop reliably.

When number sense is impaired, math isn't just difficult—it's disorienting. Numbers don't carry intuitive meaning. A person might memorize that 7 x 8 = 56 without any felt sense of why, or struggle to estimate whether a grocery bill seems right because quantities don't "feel" like anything. This isn't a failure of intelligence or effort; it's a neurological difference in how the brain processes numerical information.

Understanding number sense is important because it explains why traditional math instruction often fails for dyscalculic learners. Drilling multiplication tables doesn't build number sense any more than memorizing a dictionary builds reading comprehension. Effective approaches start with concrete, visual, and embodied representations of quantity before moving to abstract symbols.

In Practice

  • Someone asks you to split a restaurant bill four ways and your mind goes blank. You can do the arithmetic on paper, but you have no intuitive sense of what a quarter of the total should roughly be—you can't tell if your answer is in the right ballpark.
  • Your child counts on their fingers in fifth grade. A teacher says they should have outgrown that by now. But for your child, fingers are the bridge between abstract numbers and felt quantity—and removing that bridge doesn't build understanding, it removes it.

Related Terms

Clinical Context

Research by Butterworth (2005) and Dehaene (1997) established that number sense is supported by specific brain regions, particularly the intraparietal sulcus. Dyscalculia is associated with differences in this area.

Neuronormativity is the set of unspoken assumptions that treat one particular cognitive style—neurotypical—as the default, the ideal, and the measure against which all other brains are judged. It's the water we all swim in: schools are designed for neurotypical learners, workplaces are designed for neurotypical workers, and social norms are calibrated to neurotypical communication and behavior.

The concept works similarly to other "normativity" frameworks. Just as heteronormativity assumes heterosexuality is the default and everyone else must explain themselves, neuronormativity assumes neurotypical functioning is standard and neurodivergent people must justify, compensate for, or apologize for their differences.

Neuronormativity is powerful precisely because it's invisible to those who fit within it. A neurotypical person rarely has to think about why meetings are structured the way they are, why job interviews reward eye contact and small talk, or why schools measure intelligence through timed written tests. These structures feel natural and neutral—but they're not. They're designed around one type of brain and experienced as barriers by many others.

In Practice

  • A job interview evaluates you on eye contact, firm handshake, and quick verbal responses—none of which have anything to do with the actual job. You don't get hired, and the employer genuinely believes they selected the "best candidate" through an objective process.
  • Your child's school report says they "need to work on sitting still and focusing." The assumption is that stillness equals attention. For your child, movement is what enables attention—but the classroom wasn't designed for that.

Related Terms

Community Note

Naming neuronormativity does for neurodivergent people what naming other forms of structural bias does: it moves the conversation from "what's wrong with me?" to "what's wrong with a system that only works for one type of brain?"

Neurodiversity at work encompasses both the business case and the human case for building workplaces that value and accommodate different kinds of thinking. The business case is increasingly well-documented: cognitively diverse teams are better at problem-solving, innovation, and quality assurance. The human case is simpler: neurodivergent people deserve to work in environments where they can succeed.

Companies like SAP, Microsoft, JPMorgan Chase, and others have launched neurodiversity hiring programs that redesign interview processes, provide workplace accommodations, and pair neurodivergent employees with mentors. These programs have shown strong results—not because neurodivergent people were given advantages, but because barriers were removed that had been preventing their contributions.

The deeper shift isn't about special programs for special people. It's about recognizing that traditional workplace norms—open offices, real-time verbal communication, rigid schedules, social-performance-based interviews—were designed for one kind of brain and accidentally exclude many others. Fixing this isn't charity; it's organizational design.

In Practice

  • Your company redesigns its interview process to include work samples instead of behavioral questions. They intended it for neurodivergent candidates, but the hiring quality improves across the board because they're now testing for ability instead of social performance.
  • A team includes someone who notices patterns nobody else sees, someone who documents everything meticulously, and someone who challenges assumptions relentlessly. They were hired for their "deficits" under old criteria. Their strengths changed the team's trajectory.

Related Terms

Community Note

Neurodiversity at work programs are a step forward, but many neurodivergent employees note that being hired through a "special program" can feel othering. The goal isn't separate tracks for different brains—it's a single track designed for cognitive diversity from the start.

In developmental psychology, object permanence is the understanding that objects continue to exist when you can't see them—a skill that develops in infancy. In ADHD communities, the term has been borrowed (somewhat loosely) to describe the experience of things ceasing to exist in your working awareness when they're not directly visible.

This isn't a true lack of object permanence—you know intellectually that the food is in the fridge and your friend still exists. But your brain doesn't maintain active awareness of things outside your current sensory field. The leftovers are forgotten until you clean the fridge and find them. The friend you haven't seen in months drops off your mental radar entirely—not because you don't care, but because your working memory didn't keep them loaded.

This pattern affects everything from organization (if you can't see it, you won't use it) to relationships (if you don't see someone regularly, you forget to reach out) to self-care (if the vitamins are in a cupboard, they don't get taken). The most effective coping strategies involve making important things visible: clear containers, open shelving, regular scheduled contact with friends, and reminders placed in your direct line of sight.

In Practice

  • You bought groceries with great intentions. A week later, you find wilted vegetables in the produce drawer. You didn't forget they existed exactly—you just never thought about them once the drawer was closed.
  • You haven't texted your best friend in two months. You love them deeply. But they live in another city and without the visual reminder of seeing them, your brain simply stopped prompting you to reach out.

Related Terms

Community Note

ADHD communities have adopted "object permanence" with some debate—some clinicians argue the term is being misused. But the community response is that the experience is real, it desperately needed a name, and this one stuck because it captures the feeling perfectly.

OCD (obsessive-compulsive disorder) is a condition characterized by intrusive, unwanted thoughts (obsessions) and repetitive behaviors or mental acts performed to reduce the anxiety those thoughts create (compulsions). It co-occurs frequently with autism (about 17-37% overlap) and ADHD, and is often misunderstood by the general public as a preference for neatness or organization.

The reality of OCD is far more distressing than the stereotype. Obsessions are ego-dystonic—they go against the person's values and desires. A person might have intrusive thoughts about harming someone they love, contamination fears that prevent them from touching doorknobs, or a persistent doubt that they left the stove on despite checking seven times. The compulsions (checking, washing, counting, arranging, mental reviewing) provide temporary relief but reinforce the cycle.

In neurodivergent people, distinguishing OCD from other traits can be complex. Autistic routines and rigidity can look like OCD compulsions. ADHD's difficulty with cognitive "braking" can feed obsessive thought loops. The key distinction is distress: autistic routines typically feel comforting and desired, while OCD compulsions feel forced and unwanted. Accurate identification matters because the treatment approaches differ significantly.

In Practice

  • You check that the door is locked. Then you check again. Then again. You know it's locked—you watched your hand turn the lock. But the doubt doesn't resolve, and leaving without checking one more time produces unbearable anxiety.
  • Someone says "I'm so OCD about my desk being neat." You want to explain that your OCD involves hours of intrusive thoughts that make you cry, not a tidy desk—but you know the comparison won't land.

Commonly Confused With

Autistic routines

Autistic routines and rituals are typically ego-syntonic—they feel right and provide comfort. OCD compulsions are ego-dystonic—they feel forced and the person wishes they could stop. Both involve repetitive behavior, but the internal experience is fundamentally different.

Related Terms

Clinical Context

OCD is classified as an anxiety-related disorder in the DSM-5. It affects approximately 2-3% of the general population, with higher rates in autistic populations. First-line treatment is exposure and response prevention (ERP), a specific form of CBT.

Community Note

The casual use of "OCD" as a synonym for "neat" or "particular" trivializes a condition that can be severely disabling. Many people with actual OCD feel they can't talk about their experience because the stereotype has replaced the reality in public understanding.

A premonitory urge is the sensory experience that precedes most tics. It's often described as a building pressure, itch, tightness, or uncomfortable sensation in a specific part of the body that intensifies until the tic is performed. Once the tic happens, the sensation temporarily resolves—only to build again.

Not everyone with a tic disorder experiences premonitory urges, but most do. Studies suggest that around 90% of adults with Tourette syndrome report them. Children may be less aware of the sensation or less able to describe it, which is why premonitory urges are sometimes only recognized in retrospect.

Understanding premonitory urges matters because they're central to one of the most effective tic management approaches: Comprehensive Behavioral Intervention for Tics (CBIT). CBIT teaches people to recognize the urge and respond with a competing behavior instead of the tic. This doesn't eliminate the urge, but it gives people more agency over their response to it—which can be genuinely life-changing.

In Practice

  • You feel a growing tightness in your shoulder that won't stop until you shrug. You try to hold it, but the sensation gets louder and louder until it's all you can focus on. The shrug brings about three seconds of relief.
  • A friend asks what having tics feels like. The best analogy you've found: "Imagine you need to sneeze, but the sneeze won't come. That desperate, building feeling? That's what happens before every tic, all day long."

Related Terms

Clinical Context

Leckman, J. F., et al. (1993) described premonitory urges as a core feature of Tourette syndrome. The presence and awareness of these urges is a predictor of success with CBIT, the leading behavioral intervention for tics.

Community Note

Many people with tics say the premonitory urge is worse than the tic itself. The tic is brief; the urge is constant. This is why suppressing tics is so exhausting—you're not just holding back a movement, you're enduring an unrelenting sensation.

Proprioception is the sense that tells your brain where your body parts are in relation to each other and to the environment. It's why you can touch your nose with your eyes closed, walk without watching your feet, and gauge how much force to use when picking up a glass. When proprioception is unreliable, the physical world becomes harder to navigate.

Proprioceptive differences are common in autism, dyspraxia, and ADHD. They can show up as clumsiness (bumping into doorframes, misjudging distances), difficulty with fine motor tasks, poor posture, or a need for deep pressure input (heavy blankets, tight hugs, compression clothing). The person isn't being careless—their brain is receiving imprecise information about where their body is.

Many people with proprioceptive differences instinctively seek out input that helps calibrate their system: leaning against walls, sitting on their feet, chewing on things, or craving intense physical activity. These behaviors are often regulatory—they're providing the proprioceptive feedback the brain needs to feel grounded in physical space.

In Practice

  • You bruise your hip on the same counter corner every week. You know it's there. You've lived in this apartment for years. Your brain just consistently miscalculates how much space your body takes up.
  • You love the feeling of a heavy blanket—not just for warmth, but because the weight tells your nervous system exactly where your body is. Without it, you feel vaguely untethered.

Related Terms

Clinical Context

Proprioception is processed through receptors in muscles, joints, and tendons. Differences in proprioceptive processing are well-documented in autism and developmental coordination disorder, and are a key focus of occupational therapy interventions.

Community Note

When neurodivergent people describe themselves as "clumsy," proprioception is often the missing explanation. Understanding it reframes a lifetime of bumps and spills from personal failure to sensory processing difference.

Perfectionism in neurodivergent people often starts as a survival strategy. When your executive function is unreliable, when you've been criticized for careless mistakes, when you know your brain might miss something obvious—doing everything perfectly feels like the only way to stay safe. If you check the email five times, maybe you won't miss the typo. If you over-prepare, maybe you won't be caught off guard.

The problem is that perfectionism is unsustainable, especially for brains that already burn more energy on routine tasks. The standards keep rising because "good enough" has never been a reliable standard for you. You've been burned by "good enough" before—something slipped through, someone noticed, and the shame was devastating. So the bar goes higher and higher until nothing gets finished because nothing meets the standard.

This creates a painful paradox: the person appears lazy or unproductive, but they're actually paralyzed by standards so high that starting feels pointless. Perfectionism and procrastination are two sides of the same coin—both are responses to the fear that your output will reveal the gaps you're desperately trying to hide.

In Practice

  • You spend four hours formatting a document that needed to be "pretty good." You know it's excessive. But the last time you sent something with a formatting error, a colleague pointed it out in a meeting, and the shame lasted for days.
  • You have three half-finished projects because each one hit a point where it wasn't meeting your standard. Starting something new feels easier than confronting the gap between what you imagined and what you produced.

Related Terms

Community Note

Perfectionism in neurodivergent people is often praised rather than recognized as compensatory. "You're so thorough!" masks the reality that thoroughness is driven by terror. Recognizing perfectionism as a trauma response rather than a personality trait changes the approach to addressing it.

Perseveration is the involuntary repetition of a particular response—a thought, a word, a behavior, an activity—beyond the point where it serves a purpose. It's different from a habit or preference; perseveration happens because the brain's "switching" mechanism isn't responding. You want to move on. You can't.

In ADHD, perseveration might look like replaying an awkward conversation in your head for hours, or continuing to research a topic long after you've found the answer you needed. In autism, it can involve difficulty transitioning between activities, returning to the same topic repeatedly in conversation, or getting locked into a routine that's no longer functional. In both cases, the underlying issue is the same: the brain's ability to shift attention or behavior is impaired.

Perseveration can be confused with obsession, but the mechanism is different. Obsessive thoughts are driven by anxiety; perseveration is driven by cognitive inflexibility. You're not stuck because you're worried—you're stuck because your brain's gear-shift isn't engaging.

In Practice

  • You said something awkward in a meeting at 10 AM. At midnight, you're still replaying it. You've analyzed it from every angle, concluded it doesn't matter, and your brain is still looping. The analysis is done; the repetition continues.
  • Your child is playing with blocks and it's time for dinner. They don't resist because they don't want to eat—they resist because their brain is locked into the current activity and the transition mechanism isn't firing.

Commonly Confused With

Rumination

Rumination involves actively thinking through a problem or event, often with an anxious or depressive quality. Perseveration is more mechanical—the repetition continues not because of emotional investment but because the brain's ability to shift has stalled.

Related Terms

Clinical Context

Perseveration is a well-documented feature of executive dysfunction, observed across ADHD, autism, traumatic brain injury, and other neurological conditions. It involves the prefrontal cortex and its role in cognitive flexibility and set-shifting.

Pathological demand avoidance (PDA) is a profile increasingly recognized within the autism spectrum, characterized by an overwhelming, anxiety-based need to avoid or resist demands. The "demands" aren't just instructions from others—they include self-imposed expectations, routine tasks, and even activities the person wants to do. The avoidance isn't willful defiance; it's a nervous system response to perceived threats to autonomy.

PDA presents differently from typical autism in ways that often delay or prevent diagnosis. People with PDA may be socially motivated (unlike the stereotype of autistic social withdrawal), use sophisticated avoidance strategies (humor, distraction, excuses, taking control of situations), and appear comfortable in social settings while internally being in constant fight-or-flight about demands.

The demand avoidance can apply to anything: getting dressed, eating meals, going to school, attending events they're looking forward to, or following their own plans. The intensity can fluctuate—some days a simple request is manageable, other days it triggers a panic response. Traditional behavioral approaches (reward charts, consequences, firm boundaries) typically make PDA worse because they increase the perceived demand.

In Practice

  • You plan a fun outing for yourself. The morning arrives and you can't go. Nothing went wrong—but the fact that it's now a thing you "have to" do transforms it from appealing to threatening. You cancel and feel both relieved and confused.
  • Your child's teacher says they're "oppositional" because they refuse simple requests. But the child complies happily when requests are framed as choices or games. It's not the task they're resisting—it's the demand.

Clinical Context

PDA was first described by Elizabeth Newson in 2003. It is recognized by the PDA Society and increasingly in clinical practice, particularly in the UK, though it is not yet a separate diagnostic category in the DSM-5 or ICD-11.

Community Note

PDA is one of the most debated profiles in neurodivergent communities. Some see it as a distinct condition; others view it as an expression of autistic anxiety. What most agree on is that punitive approaches backfire—flexibility, collaboration, and reducing perceived demands are far more effective.

Prosopagnosia, commonly called face blindness, is the inability or difficulty recognizing faces. It ranges from mild (difficulty recognizing acquaintances out of context) to severe (not recognizing family members or one's own face in a mirror). The condition is more prevalent in autistic populations than in the general population, though it can occur independently.

People with prosopagnosia typically develop workarounds: recognizing others by hairstyle, voice, clothing, gait, context, or distinctive features. These strategies work until they don't—when someone changes their hairstyle, or when you encounter them in an unexpected location. The social consequences can be significant: accidentally ignoring someone you know, failing to recognize a colleague at a conference, or not recognizing a friend who's waving at you from across the street.

Prosopagnosia isn't about not paying attention or not caring about people. It's a specific difference in how the brain's fusiform face area processes facial information. Some researchers believe the higher prevalence in autistic people relates to broader differences in how autistic brains process visual information—focusing on details rather than the holistic gestalt of a face.

In Practice

  • A colleague you've worked with for two years walks past you in the grocery store and says hello. You smile back but have no idea who they are—out of the office context, without the usual desk and outfit, their face alone doesn't register.
  • You watch a movie and can't follow the plot because you can't tell two characters apart. They have different names and different storylines but similar hair color, and your brain files them as the same person.

Related Terms

Clinical Context

Prosopagnosia affects approximately 2% of the general population but is more prevalent in autistic individuals. Research suggests it may be related to differences in holistic face processing, with autistic people tending to process faces feature-by-feature rather than as a whole.

Community Note

Many autistic people don't realize they have prosopagnosia until adulthood—they assume everyone has the same difficulty and develop such effective workarounds that the underlying face-recognition issue remains hidden.

R

Rejection Sensitive Dysphoria describes the overwhelming emotional pain triggered by the perception—real or imagined—of being rejected, criticized, or falling short. For people with ADHD, this isn't garden-variety hurt feelings. RSD can feel like a physical gut-punch that derails your entire day.

RSD operates on a hair trigger: a slightly flat tone in a text message, a raised eyebrow in a meeting, or constructive feedback on a project can set off an emotional firestorm that feels completely disproportionate to the trigger. The pain is real and intense, even when the logical brain knows the reaction doesn't match the situation.

RSD can drive three common behavioral patterns: people-pleasing to an extreme (avoiding any possibility of rejection), avoiding situations where rejection is possible (not applying for jobs, not sharing work, not initiating social contact), or intense emotional outbursts that feel uncontrollable. Understanding RSD helps explain why many people with ADHD struggle with perfectionism, social anxiety, and relationship patterns that seem irrational from the outside.

In Practice

  • You send a message to a friend and they don't reply for hours. Instead of assuming they're busy, you're convinced they hate you and spend the rest of the afternoon replaying every interaction looking for what you did wrong.
  • Your manager gives you positive feedback with one small suggestion for improvement. You can't hear anything except the criticism, and you're convinced you're about to be fired.

Commonly Confused With

Social anxiety

While both involve fear of negative evaluation, RSD is an acute emotional response that hits fast and hard, while social anxiety is more of a chronic anticipatory worry. RSD can also be triggered by self-perceived failure, not just social situations.

Clinical Context

RSD is not currently recognized as an official diagnosis in the DSM-5. It was popularized by Dr. William Dodson and is widely discussed in ADHD clinical practice.

Community Note

Many in the ADHD community consider RSD one of the most impactful but least-discussed aspects of ADHD. The term has been life-changing for people who spent years thinking they were "just too sensitive."

Reasonable accommodations are modifications or adjustments to a job, work environment, or hiring process that enable a qualified person with a disability to participate equally. Under the Americans with Disabilities Act (ADA) and similar laws in other countries, employers are legally required to provide reasonable accommodations unless doing so would cause "undue hardship."

For neurodivergent employees, accommodations might include written instructions instead of verbal ones, noise-canceling headphones in open offices, flexible scheduling, permission to work from home, extra time on written tasks, or regular check-ins instead of annual reviews. The key word is "reasonable"—the accommodation needs to be effective for the employee without fundamentally altering the nature of the job.

Many neurodivergent people don't request accommodations because they don't know they can, fear being stigmatized, or don't have a formal diagnosis. Others have found that framing requests in terms of productivity ("I do my best work when...") rather than disability ("I need this because of my ADHD") can be more effective in workplaces that aren't yet disability-literate.

In Practice

  • You ask your manager if you can wear noise-canceling headphones during focus work. They agree, and your productivity doubles—not because you were slacking before, but because the open office was making it impossible for your brain to filter out background noise.
  • A student with ADHD receives extended time on exams. A classmate calls it "unfair." The accommodation doesn't give an advantage—it levels a playing field that was already tilted.

Related Terms

Clinical Context

The ADA defines disability broadly enough to include many neurodivergent conditions. Accommodations are determined through an interactive process between the employee and employer.

Community Note

There's a growing movement to shift from individual accommodation requests to universal design—building workplaces and classrooms that work for diverse brains by default, so fewer people need to disclose and ask for special treatment.

Rumination is the pattern of repeatedly going over past events, conversations, or perceived failures in your mind. Everyone does it sometimes, but for neurodivergent people—especially those with ADHD, autism, or anxiety—rumination can become a consuming, default state that eats hours and disrupts sleep.

The neurodivergent flavor of rumination often has specific triggers. For people with ADHD, rejection sensitive dysphoria can turn a mildly critical comment into hours of replay. For autistic people, social interactions that require real-time decoding of unwritten rules provide endless material for post-event analysis: "Did I say the wrong thing? Was that look meaningful? Should I have laughed there?"

What makes rumination especially tricky is that it feels productive. Your brain tells you that if you just replay the conversation one more time, you'll figure out what went wrong and prevent it next time. But rumination doesn't solve problems—it rehearses pain. The exit usually isn't more analysis; it's interrupting the loop through sensory input, physical movement, or deliberate attention redirection.

In Practice

  • You sent a text that wasn't acknowledged. Three hours later, you've constructed an elaborate narrative about how the person is angry at you, what you did wrong, and how the friendship is probably over. They were just busy.
  • You wake up at 3 AM replaying a conversation from five years ago. You know it doesn't matter. You know no one else remembers it. Your brain doesn't care—it has decided this is urgent.

Related Terms

Community Note

Many neurodivergent people describe developing "rumination routines"—specific activities that reliably break the loop. For some it's exercise, for others it's engaging a different cognitive system (like doing math or playing music). Finding your pattern interrupt is one of the most valuable self-knowledge tools.

Revenge bedtime procrastination is the decision to delay sleep in order to carve out leisure time that the day didn't provide. The "revenge" is against a schedule that left no room for your own interests, your own pace, or your own choices. The late-night hours feel like the only time that truly belongs to you—even though you know you'll pay for it tomorrow.

For neurodivergent people, this pattern is amplified by several factors. ADHD brains are often more alert and creative at night, when external demands quiet down and dopamine-seeking can happen freely. The executive dysfunction that made the day exhausting also makes it hard to initiate the bedtime routine. And the emotional need for unstructured, self-directed time is greater when you've spent the day masking, compensating, and meeting neurotypical expectations.

The term originated in Chinese social media culture (bàofùxìng áoyè, "revenge staying up late") and resonated globally because the experience is universal—but especially intense for people whose days require more cognitive and emotional labor than the average person realizes.

In Practice

  • It's midnight and you have a 7 AM alarm. You're not doing anything important—scrolling, watching videos, reading random articles. But going to bed means the day is over and tomorrow starts, and you haven't had a single moment of unstructured freedom yet. So you stay up.
  • You know you need sleep. You've read the research. You set a bedtime alarm at 10 PM every night. At 10 PM, your brain says "absolutely not" and you begin the three-hour ritual of doing whatever you want for the first time all day.

Related Terms

Community Note

Revenge bedtime procrastination is one of those terms that people with ADHD hear and immediately recognize. The advice to "just go to bed earlier" misses the point entirely—the problem isn't ignorance about sleep; it's a nervous system that hasn't been fed all day finally demanding its turn.

Regulation refers to the ability to manage your internal state—emotional, sensory, physiological, and cognitive—in response to changing demands. Self-regulation means managing this internally; co-regulation means doing it with the support of another person. Both are essential, and both work differently in neurodivergent people.

For many neurodivergent people, self-regulation is less automatic and more effortful. A neurotypical person might unconsciously adjust their emotional response in a stressful meeting. A neurodivergent person may need to consciously deploy a strategy—deep breathing, fidgeting, reframing—and even then, the regulation may be unreliable. This isn't a skill deficit; it's a difference in the neurological systems that support automatic regulation.

Co-regulation—using another person's calm presence to help regulate your own state—is especially important for neurodivergent people and is often underrecognized in adults. A partner who sits quietly with you during overwhelm, a friend who helps you process an emotional event, or a therapist who provides a regulated presence are all forms of co-regulation. The cultural emphasis on self-regulation as the only "mature" approach misses the reality that all humans need co-regulation—neurodivergent people may just need it more visibly.

In Practice

  • You notice your frustration building in a meeting and consciously start a grounding technique—pressing your feet into the floor, breathing slowly, rubbing a fidget stone. A neurotypical colleague does the same thing automatically, without thinking about it. Same outcome, different effort.
  • Your child can't calm down alone after a meltdown, but they settle quickly when you sit next to them and breathe slowly. That's not dependence—that's co-regulation, and it's a legitimate regulatory strategy at any age.

Related Terms

Community Note

The neurodivergent community is pushing back against the idea that everyone should be able to self-regulate independently. Co-regulation is normal, healthy, and human. Needing support to regulate isn't a failure—it's a need, like any other.

Sensory overload happens when the brain receives more sensory information than it can effectively process. For neurotypical people, the brain automatically filters out background noise, visual clutter, and minor physical sensations. For many neurodivergent people, this filter works differently—or doesn't work at all—meaning everything comes in at full volume, all the time.

Overload can build gradually (a long day of fluorescent lights and open-plan office noise) or hit suddenly (walking into a crowded, loud restaurant). The experience varies: some people describe it as physical pain, others as a feeling of drowning, and others as their brain "shutting off" to protect itself.

Sensory overload is a key feature of autism and sensory processing differences, but it also affects people with ADHD, PTSD, and other conditions. It's not a preference or a mood—it's a neurological event. Understanding this helps reframe behaviors like leaving events early, wearing noise-canceling headphones, or needing recovery time after social outings as legitimate self-regulation, not antisocial behavior.

In Practice

  • You're at a family gathering and the combination of multiple conversations, a TV playing, kids screaming, and strong food smells makes you feel like your skin is crawling. You retreat to the bathroom just to think clearly.
  • After a day of back-to-back video calls with their notification sounds, screen glare, and the effort of reading facial expressions on a small screen, you can't tolerate any additional input—even your partner talking feels unbearable.

Related Terms

Clinical Context

Sensory reactivity is recognized in the DSM-5 under autism spectrum disorder diagnostic criteria (Criterion B) as hyper- or hypo-reactivity to sensory input.

Community Note

Many autistic adults say that understanding sensory overload was the single most useful part of their diagnosis—it reframed years of "I'm just bad at parties" into "my nervous system is doing something specific and manageable."

A special interest is a deep, focused engagement with a particular subject, activity, or domain that is characteristic of autistic experience. Unlike casual hobbies, special interests often involve an encyclopedic depth of knowledge, significant time investment, and a level of joy and satisfaction that's hard to find elsewhere.

Special interests can last years or a lifetime, or they can rotate through phases. They serve important functions: emotional regulation (returning to a special interest when stressed), identity and self-expression, social connection (finding community around shared interests), and genuine expertise. Many autistic people build careers around their special interests.

The clinical literature has historically pathologized special interests as "restricted" or "repetitive" behaviors, but the autistic community widely rejects this framing. For most autistic people, special interests are a source of meaning, competence, and happiness—not a problem to be solved. The issue arises only when external demands prevent someone from engaging with their interests, or when interests are dismissed as "obsessive."

In Practice

  • You've been deeply into trains since you were four years old. You know the engineering specifications of every major locomotive model, and explaining them to someone who's genuinely interested is one of the best feelings in the world.
  • Your current special interest is a specific historical period. You've read 30 books, joined three online forums, and can talk about it for hours—but you also know most people's eyes glaze over after five minutes, so you've learned to read the room.

Commonly Confused With

Obsession

Obsessions (as in OCD) are intrusive, unwanted, and distressing. Special interests are typically voluntary, deeply enjoyable, and a source of positive emotion. The difference is in how the person feels about the focus—pleasure vs. distress.

Related Terms

Community Note

The reframing from "restricted interest" to "special interest" reflects a broader shift toward understanding autistic traits as differences rather than deficits. Many autistic adults feel their special interests are the most authentic part of who they are.

Spoon theory was created by Christine Miserandino in 2003 to explain the experience of living with lupus, but it has been widely adopted by the neurodivergent and disabled communities as a way to communicate about energy management.

The core idea: imagine you start each day with a limited number of "spoons." Every activity—getting dressed, commuting, having a conversation, making a decision, managing sensory input—costs one or more spoons. Neurotypical and non-disabled people might have a large supply that replenishes easily. People with chronic illness, neurodivergent conditions, or disabilities often start with fewer spoons, and activities that seem "easy" to others can cost significantly more.

The power of spoon theory is that it makes invisible energy costs visible and communicable. Saying "I'm out of spoons" is a quick way to say "I physically and mentally cannot do more right now, and it's not about willpower or interest." It's especially useful for explaining why someone can seem fine one day and completely depleted the next—the spoon count varies.

In Practice

  • You wake up with maybe 12 spoons. Showering costs 2, commuting costs 3, a morning of meetings costs 4. By lunch, you have 3 spoons left and still need to cook dinner, help with homework, and respond to texts. Something has to give.
  • A friend invites you to dinner on a day when you're already at 1 spoon. You decline not because you don't want to go, but because accepting would put you in energy debt that takes days to repay.

Related Terms

Community Note

Some people prefer "battery theory" or "energy accounting" as alternatives. The specific metaphor matters less than the principle: energy is finite, unequally distributed, and deserves respect.

Stimming (short for self-stimulatory behavior) includes any repetitive action that provides sensory input: rocking, hand-flapping, spinning, humming, clicking pens, chewing things, fidgeting, tapping, hair-twirling, or countless other variations. Everyone stims to some degree (think: bouncing your leg in a boring meeting), but stimming is more frequent, more necessary, and more varied in autistic and ADHD experience.

Stimming serves multiple functions. It can help regulate overwhelming emotions (rocking when anxious), provide needed sensory input (chewing stim toys for oral input), process information (pacing while thinking), express excitement or joy (hand-flapping when happy), or simply feel good. It's not a behavior problem—it's a regulatory tool.

Historically, many therapies (especially ABA) aimed to eliminate stimming, treating it as a behavior to be suppressed. The neurodivergent community has pushed back strongly against this approach, arguing that suppressing stims removes a vital coping mechanism and teaches people that their natural responses are shameful. The modern understanding is that stims should be supported unless they're genuinely self-harmful.

In Practice

  • In a stressful meeting, you rub a smooth stone in your pocket. Nobody can see it, but it's keeping your nervous system regulated enough to focus on the conversation.
  • Your child flaps their hands when they're excited about something. A well-meaning relative tells them to stop. You explain that hand-flapping is how their body expresses joy, and there's nothing wrong with it.

Commonly Confused With

Tics

Tics (as in Tourette syndrome) are involuntary and often unwanted movements or vocalizations. Stims are typically voluntary (though sometimes automatic) and serve a regulatory function. Tics happen to you; stims are something you do for yourself.

Related Terms

Clinical Context

Stimming is referenced in the DSM-5 under ASD diagnostic criteria as "stereotyped or repetitive motor movements." The neurodivergent community and some researchers advocate for reframing this as a regulatory behavior rather than a symptom.

Community Note

The phrase "stim freely" has become a rallying call in neurodivergent communities, encouraging people to unmask their natural regulatory behaviors. Many adults describe the relief of finally allowing themselves to stim openly after years of suppression.

Sensory processing differences describe the wide range of ways neurodivergent brains handle sensory input differently from the statistical norm. This can include hypersensitivity (experiencing sensory input as more intense), hyposensitivity (needing more input to register it), or a combination of both across different senses.

A person might be hypersensitive to sound (a ticking clock is unbearable) while being hyposensitive to pain (not noticing a cut until they see blood). These profiles are highly individual—no two people have the same sensory landscape.

Sensory processing differences are central to the autistic experience but also affect people with ADHD, SPD (Sensory Processing Disorder), and other conditions. Understanding your own sensory profile is one of the most practical tools for managing daily life—it transforms confusing meltdowns and shutdowns into predictable, manageable responses to identifiable triggers.

In Practice

  • You cut the tags out of all your clothes because the feeling against your skin is genuinely distracting to the point of pain. People think you're being fussy. You're managing a sensory system that registers texture at a different volume.
  • You love spicy food but can't handle the texture of mashed potatoes. Flavor and texture are processed differently, and your sensory system has strong opinions about both.

Related Terms

Clinical Context

Sensory processing differences are included in the DSM-5 autism criteria as "hyper- or hyporeactivity to sensory input or unusual interest in sensory aspects of the environment."

Community Note

Many autistic adults find that creating a "sensory profile"—a personal map of what inputs they seek, tolerate, and avoid—is one of the most useful post-diagnosis tools. It turns mysterious discomfort into actionable information.

A shutdown is a meltdown's quieter sibling. Where a meltdown involves an outward explosion of emotion, a shutdown involves an inward collapse. The person may become nonverbal or limited in speech, physically still, emotionally flat, and seemingly "checked out." It's the nervous system's way of slamming the brakes when everything is too much.

Shutdowns can be harder to recognize than meltdowns because they don't look dramatic from the outside. A person in shutdown might seem like they're just being quiet, distant, or unresponsive. Internally, they may feel frozen, foggy, unable to process language, or dissociated from their surroundings. It's not a choice to withdraw—it's a protective neurological response.

Shutdowns can be triggered by the same things that cause meltdowns: sensory overload, social exhaustion, cognitive demands, emotional stress, or an accumulation of smaller stressors. Some people tend toward meltdowns, others toward shutdowns, and many experience both at different times. Recovery requires time, reduced demands, and often a low-stimulation environment.

In Practice

  • During an argument, your partner is waiting for a response but words have stopped coming. You can hear them talking but can't process the meaning. You're not ignoring them—your brain has gone offline.
  • After a long conference day, you get back to your hotel room and sit on the bed in silence for an hour. You can't scroll your phone, can't watch TV, can't even think clearly. Your system has shut down to recover.

Related Terms

Community Note

Shutdowns are often invisible to others, which means the person rarely receives support or understanding during one. Many autistic people say they wish people understood that going quiet isn't passive aggression—it's a genuine loss of capacity.

Safe foods are the foods a person can consistently eat without triggering sensory distress. For many autistic people and others with sensory processing differences, eating isn't just about taste—it's about texture, temperature, smell, appearance, and predictability. A food that was fine yesterday might be intolerable today if the texture is slightly different, or if it's a different brand, or if it looks wrong on the plate.

The clinical literature calls this "food selectivity," and it affects an estimated 50-89% of autistic children. But framing it as selectivity implies choice. For people living it, there's nothing selective about it—certain foods trigger genuine sensory distress, from gagging to nausea to meltdowns. Safe foods are the ones that don't.

Safe foods tend to share certain qualities: predictable texture, consistent flavor, familiar appearance. This is why many people with sensory processing differences gravitate toward specific brands, specific preparations, and foods they've eaten many times before. The goal isn't variety—it's reliability. And that's a perfectly valid way to eat.

In Practice

  • You eat the same lunch every day for three months. A coworker comments on it. You don't explain that this particular sandwich, made exactly this way, is one of the few meals your body doesn't fight you on.
  • Your child will only eat one brand of chicken nuggets. You drive to a different grocery store when your usual one is out, because the other brands have a different texture and the meltdown isn't worth it.

Commonly Confused With

Picky eating

Picky eating is a preference—a child who dislikes vegetables but can eat them if pressed. Safe food needs are sensory—a person who gags on certain textures isn't being difficult; their nervous system is rejecting the input.

Related Terms

Clinical Context

Food selectivity in autism is well-documented. Cermak, Curtin, and Bandini (2010) linked food selectivity to sensory sensitivity, particularly texture sensitivity, in the Journal of the American Dietetic Association.

Community Note

The phrase "safe foods" matters because it reframes eating differences from a behavior problem to a sensory need. Many autistic adults say they spent years forcing themselves to eat foods that made them miserable because they didn't know their experience wasn't universal.

Stealth dyslexia describes the pattern where a person's strong cognitive abilities hide their dyslexic processing differences. They read at or above grade level, score well on tests, and appear to have no reading problems—but underneath, they're working two or three times harder than their peers to achieve those results. The dyslexia is there; it's just invisible.

This is a form of twice-exceptionality: the giftedness and the learning difference cancel each other out in the metrics that schools and clinicians use to identify problems. The student reads slowly but compensates with context clues and vocabulary. They misspell words but produce such strong content that teachers overlook the errors. They avoid reading aloud but nobody notices because they participate in other ways.

The cost of stealth dyslexia shows up over time. As academic demands increase, compensation strategies require more and more energy. Many people with stealth dyslexia describe hitting a wall in high school, college, or the workplace when the sheer volume of reading finally outpaces their ability to compensate. By then, years of unrecognized struggle have often taken a toll on confidence and mental health.

In Practice

  • You got straight A's through high school, but you spent three times longer on reading assignments than your classmates. Nobody ever tested you for dyslexia because your grades were "too good." The exhaustion was attributed to perfectionism.
  • Your child reads grade-level books fluently but can't spell basic words. The school says there's no problem because comprehension scores are high. You know something is off, but the numbers don't support you.

Related Terms

Clinical Context

The term was popularized by Drs. Brock and Fernette Eide, who described the pattern in their clinical work with gifted dyslexic children. Standard discrepancy-based models of dyslexia identification often miss these students because their reading scores remain in the average range.

Community Note

Stealth dyslexia resonates with many late-diagnosed adults who always knew reading was harder for them but had no framework for why—because every metric said they were fine. The gap between effort and outcome was invisible to everyone but them.

Self-diagnosis is the process of recognizing your own neurodivergence through research, community connection, and careful comparison with your lived experience, without obtaining a formal clinical diagnosis. In neurodivergent communities, self-diagnosis is widely accepted as valid—and for good reason.

Formal diagnosis is expensive, time-consuming, and inaccessible for many people. In the United States, an adult ADHD or autism assessment can cost $2,000-5,000 without insurance. Waitlists can stretch months or years. And diagnostic criteria were historically developed around white, male, childhood presentations—meaning women, people of color, and adults are systematically under-identified even when they do access assessment.

Self-diagnosis isn't about skipping rigor. Most self-diagnosed people have done extensive research, taken validated screening tools, and spent months or years comparing their experiences to clinical descriptions and community accounts. They're not claiming a label casually—they're recognizing a pattern that explains their life. The question isn't whether self-diagnosis is "real" but whether formal diagnosis should be the only acceptable path to self-understanding and community.

In Practice

  • You can't afford a $3,000 autism assessment, but after two years of research, every screening tool you've taken, and reading hundreds of autistic people's accounts, you recognize your own experience in every description. You start calling yourself autistic—because you are.
  • A clinician dismisses your concerns because you "made it this far" without a diagnosis. You know your coping mechanisms are held together with duct tape, but without a formal label, your struggles remain officially invisible.

Related Terms

Clinical Context

Research consistently shows that many neurodivergent adults, particularly women and people of color, are missed by existing diagnostic systems. Self-identification often precedes and prompts formal diagnosis when it eventually occurs.

Community Note

The phrase "self-diagnosed is valid" is a cornerstone of neurodivergent communities because it recognizes the structural barriers to formal assessment. Gatekeeping diagnosis behind cost and access means gatekeeping identity, community, and often self-compassion.

The social model of disability draws a distinction between impairment (a physical, sensory, or cognitive difference) and disability (the disadvantage caused by a society that doesn't accommodate that difference). Under this model, a wheelchair user isn't disabled by their legs—they're disabled by stairs. An autistic person isn't disabled by their neurology—they're disabled by environments that demand constant masking, sensory endurance, and social performance.

This framework emerged from disability rights activism in the 1970s and 1980s, primarily through the work of disabled scholars like Mike Oliver. It challenged the medical model, which treats disability as a problem located inside the individual that needs to be cured or managed. The social model doesn't deny that impairments exist or that they can be painful—it argues that much of the suffering attributed to disability is actually caused by inaccessible design, discriminatory attitudes, and structural exclusion.

For neurodivergent communities, the social model is foundational. It's the intellectual basis for arguing that the solution to ADHD in the workplace isn't medication alone—it's also flexible scheduling, written instructions, and sensory-friendly environments. The problem isn't just inside the person; it's also in the world around them.

In Practice

  • An autistic employee struggles in an open-plan office with flickering lights and constant interruptions. The medical model says: treat the sensory sensitivity. The social model says: change the office.
  • A dyslexic student fails timed reading tests. The medical model says: remediate the reading deficit. The social model says: question why we're measuring reading speed instead of comprehension.

Clinical Context

The social model was formalized by Mike Oliver in 1983 and has since influenced the UN Convention on the Rights of Persons with Disabilities (2006), which adopts a social-relational understanding of disability.

Community Note

The social model isn't perfect—some disabled people feel it downplays the real pain and limitation that impairments can cause. But as a tool for shifting responsibility from "broken individuals" to inaccessible systems, it remains one of the most powerful reframes in disability discourse.

Scaffolding is a teaching and support strategy that provides temporary structure to help someone accomplish a task they couldn't manage independently. Just like construction scaffolding supports a building during construction and is removed once the structure can stand on its own, cognitive scaffolding provides step-by-step guidance that's gradually reduced as competence develops.

For neurodivergent people, scaffolding addresses the gap between "knowing what to do" and "being able to do it." An ADHD brain might understand every step of a project but be unable to sequence and initiate them without external structure. An autistic brain might grasp the concept but need explicit instruction on each sub-step that a neurotypical person would infer automatically.

Effective scaffolding isn't about making things easier—it's about making the path visible. A complex project becomes five clear steps with checkpoints. An overwhelming decision becomes a structured decision tree. A blank page becomes a template with prompts. The person's intelligence and capability remain the same; the scaffolding just makes those capabilities accessible.

In Practice

  • Your manager sends you a project with a single deadline three weeks away. You freeze. When they break it into four deliverables with weekly check-ins, suddenly the path is clear and you deliver strong work. The project didn't change—the scaffolding made it accessible.
  • You teach your child to clean their room by making a visual checklist: 1) Put clothes in hamper, 2) Put toys in bins, 3) Put books on shelf. Without the list, "clean your room" is an impossible instruction. With it, each step is one small action.

Community Note

There's a stigma around needing scaffolding—the assumption that adults should be able to manage tasks independently. But most workplaces are already full of scaffolding for neurotypical brains: agendas, templates, checklists, project management software. Neurodivergent scaffolding just extends those structures to cover the gaps that standard tools miss.

A strengths-based approach starts with what's working rather than what's broken. Instead of defining a person by their deficits and designing interventions to remediate them, it identifies existing strengths, interests, and capabilities and uses them as the foundation for support, learning, and growth.

This matters in neurodivergent contexts because the deficit model has dominated for decades. Diagnostic processes are entirely focused on what's wrong. IEPs list areas of weakness. Therapy goals target behaviors to eliminate. While understanding challenges is important, an exclusive focus on deficits teaches neurodivergent people that they are problems to be solved rather than people with a distinctive set of strengths and needs.

In practice, a strengths-based approach might mean building a student's curriculum around their special interest, structuring a job role around an employee's areas of hyperfocus, or recognizing that the same brain that struggles with small talk might excel at systems thinking, pattern recognition, or creative problem-solving. The strengths are real—they're just easy to miss when everyone's staring at the deficits.

In Practice

  • Instead of focusing on your child's difficulty with handwriting, their occupational therapist discovers they can type 60 words per minute and builds their support plan around that existing strength.
  • Your performance review focuses entirely on your difficulty with time management. Nobody mentions that you redesigned a workflow that saved the department 20 hours a week—because strengths don't appear on the "areas for improvement" section.

Community Note

The strengths-based approach isn't about toxic positivity or pretending that challenges don't exist. It's about refusing to define people solely by what they can't do, especially when what they can do is often remarkable.

Sensory seeking is the active pursuit of intense sensory experiences. While most conversations about sensory differences focus on overload and avoidance, many neurodivergent people have sensory systems that are under-responsive—they need more input than the environment naturally provides in order to feel alert, grounded, and regulated.

Sensory seeking can involve any sense: craving loud music or bass-heavy sound, seeking out intense flavors and spicy food, wanting deep-pressure hugs or weighted blankets, gravitating toward spinning or swinging, chewing on objects, or constantly touching different textures. These aren't random preferences—they're the nervous system self-medicating with the input it needs.

Many neurodivergent people are both sensory seeking and sensory avoiding, depending on the sense and the context. The same person might crave deep pressure but be overwhelmed by light touch, or seek out loud music through headphones but be distressed by unexpected noise. This isn't contradictory—different sensory channels have different thresholds.

In Practice

  • You blast music through headphones while working—not to block out noise, but because your brain needs the intense auditory input to focus. Without it, you feel understimulated and can't engage with the task.
  • Your child hangs upside down off the couch, crashes into pillows, and spins until they're dizzy. They're not misbehaving—their vestibular system is hungry for input, and they're feeding it the only way they know how.

Clinical Context

Dunn's sensory processing framework (1997) identifies sensory seeking as one of four sensory processing patterns, characterized by high neurological threshold and active self-regulation strategies.

Community Note

Understanding sensory seeking as a legitimate need rather than attention-seeking behavior changes everything. When the need is recognized, it can be met proactively—through sensory diets, movement breaks, and environmental design—instead of being punished.

A sensory diet is a structured schedule of sensory activities tailored to an individual's specific sensory needs. Just like a food diet provides the nutrients your body needs, a sensory diet provides the sensory input your nervous system needs to function at its best. The concept was developed by occupational therapists Patricia Wilbarger and Julia Wilbarger in the 1990s.

A sensory diet might include scheduled movement breaks (jumping, swinging, heavy lifting), tactile activities (fidget tools, textured objects), proprioceptive input (weighted blanket, compression vest, wall push-ups), oral input (crunchy or chewy snacks, chew jewelry), and environmental adjustments (lighting, noise levels, seating). The specific activities depend entirely on the person's sensory profile—what they seek, what they avoid, and what calms versus alerts their system.

The power of a sensory diet is prevention rather than reaction. Instead of waiting for sensory overload and then trying to recover, a sensory diet proactively provides input that keeps the nervous system regulated throughout the day. For many neurodivergent people, especially children, a well-designed sensory diet dramatically reduces meltdowns, improves focus, and increases tolerance for challenging environments.

In Practice

  • Every morning before school, your child jumps on a trampoline for ten minutes and drinks a smoothie through a straw. It looks like play, but it's calibrated proprioceptive and oral input that sets their nervous system up to handle the classroom.
  • You schedule a walk after every two hours of desk work—not for fitness, but because your body needs the movement input to stay regulated. Without it, you're fidgeting, distracted, and increasingly agitated by afternoon.

Clinical Context

The sensory diet concept was developed by occupational therapists Patricia Wilbarger and Julia Wilbarger. It is a core intervention strategy in sensory integration therapy and is widely used in pediatric occupational therapy.

Community Note

Adults often create informal sensory diets without knowing the term—the morning run, the midday walk, the evening weighted blanket. Recognizing these habits as sensory regulation rather than just "preferences" helps you protect them when life gets busy.

A sensory toolkit is a collection of items and strategies that help a neurodivergent person manage their sensory environment. Think of it as a first-aid kit for the nervous system: tools you carry or keep nearby so you can regulate when the environment becomes overwhelming or understimulating.

Common toolkit items include noise-canceling headphones or earplugs for auditory management, sunglasses or tinted lenses for visual sensitivity, fidget tools for tactile and proprioceptive input, chew jewelry for oral sensory needs, a favorite scent (essential oil roller, scented lotion) for olfactory grounding, and comfort items with familiar textures. Digital tools count too: calming playlists, white noise apps, and timer apps for managing transitions.

Building a sensory toolkit is deeply personal. What works for one person's nervous system might be triggering for another's. The process of figuring out what helps is itself valuable—it builds sensory self-awareness and gives you language for your needs. Having the toolkit available also reduces anxiety about entering unpredictable environments, because you know you have backup.

In Practice

  • You never leave the house without earplugs, tinted glasses, and a fidget ring. Your bag is heavier than it needs to be, but the alternative—being caught in a sensory-hostile environment without tools—is worse.
  • Your child's school bag has a "calm kit" inside: a fidget cube, noise-dampening earmuffs, and a chewy necklace. Their teacher knows to let them access it when needed. It cut classroom meltdowns in half.

The normalization of sensory tools has been one of the most visible shifts in neurodivergent culture. Fidget spinners went mainstream, loop earplugs became a trend, and weighted blankets are now sold at Target. The tools aren't new—the acceptance is.

Scripting is the practice of preparing verbal exchanges in advance: rehearsing what you'll say in a conversation, planning responses to anticipated questions, and mentally running through social scenarios before they happen. For many autistic people, scripting is a core strategy for navigating a social world that doesn't come with intuitive instructions.

Where neurotypical social interaction relies heavily on real-time improvisation—reading cues, generating appropriate responses on the fly, adjusting tone based on feedback—autistic interaction often requires conscious processing of each element. Scripting handles some of this processing in advance, reducing the real-time cognitive load of conversation.

Scripts can range from simple (planning a greeting and a few conversation starters before a party) to extensive (rehearsing every possible branch of an important conversation, including the other person's likely responses). Many autistic people script without realizing it—the practice is so ingrained that it feels like "just thinking about what to say," when in fact the level of preparation far exceeds what neurotypical people do.

In Practice

  • Before a phone call, you write out what you're going to say, including your opening line, your main points, and responses to three possible directions the conversation might go. Your partner thinks you're writing a speech. You're writing a survival guide.
  • You mentally rehearse ordering coffee so thoroughly that when the barista asks an unexpected question—"What size?"—your entire script derails and you freeze. The unpredictable interaction breaks the pattern your brain prepared for.

Community Note

Scripting is one of those autistic experiences that people often don't realize is unusual until they hear other people describe not doing it. The realization that most people genuinely improvise their way through conversations—without a plan—can be genuinely shocking.

  • Unmasking Autism by Devon Price (Book)

Selective mutism is a condition where a person is unable to speak in specific social situations—often school, work, or unfamiliar settings—despite speaking fluently in others, typically at home with family. The "selective" part is misleading: the person isn't choosing when to speak. Their speech system shuts down involuntarily in response to anxiety, social pressure, or sensory overload.

Selective mutism is classified as an anxiety disorder in the DSM-5 and frequently co-occurs with autism, social anxiety, and sensory processing differences. In autistic people, it can be particularly complex: the mutism may be triggered not just by anxiety but by cognitive overload, processing demands of real-time conversation, or the energy cost of masking. Some autistic people experience situational mutism as a form of shutdown—the speech system goes offline when overall capacity is exceeded.

The most important thing to understand about selective mutism is that it isn't willful. The person isn't refusing to speak, being rude, or seeking attention. They want to speak—often desperately—and the words simply won't come. Pressure to speak typically makes it worse, while patience and alternative communication methods (writing, typing, gestures) can help bridge the gap.

In Practice

  • At home, your child narrates their entire day in vivid detail. At school, their teacher reports they haven't said a word in three months. Both things are true. The setting changed; the capacity followed.
  • You can speak fine in one-on-one conversations but go completely silent in group meetings. You have things to contribute—your brain composed them perfectly—but when you open your mouth, nothing comes out.

Commonly Confused With

Shyness

Shy people feel uncomfortable speaking but can push through when needed. Selective mutism involves a genuine inability to produce speech in certain contexts—the mechanism is closer to a freeze response than to social discomfort.

Related Terms

Clinical Context

The DSM-5 classifies selective mutism as an anxiety disorder. It affects approximately 0.7-2% of children, with higher rates in autistic populations. Behavioral and cognitive-behavioral treatments focused on gradual exposure have the strongest evidence base.

A spiky profile describes the pattern of dramatically uneven abilities that's characteristic of many neurodivergent people. Instead of abilities clustering around a single level (as they tend to in neurotypical development), neurodivergent abilities spike high in some areas and dip low in others. A person might have graduate-level verbal reasoning and elementary-level organizational skills. Or exceptional visual-spatial abilities alongside severe difficulty with reading.

Spiky profiles create unique challenges because the world expects consistency. If you can write a brilliant essay, people assume you can also remember to submit it on time. If you can solve complex mathematical proofs, people assume you can also manage basic life tasks. The gap between peaks and valleys is itself disabling—not because of the valleys alone, but because of the expectations created by the peaks.

This unevenness is also why many neurodivergent people fall through diagnostic cracks. Their strengths mask their struggles. Their IQ scores average out to "normal" even though nothing about their cognitive profile is average. They're "too smart" for disability services and "too struggling" for gifted programs—the spiky profile doesn't fit systems designed for smooth ones.

In Practice

  • Your neuropsychological assessment shows verbal reasoning in the 99th percentile and processing speed in the 12th percentile. Your psychologist says the gap itself is diagnostically significant—no single number captures your brain.
  • You can build a website from scratch but can't consistently remember to eat lunch. People see the website and dismiss the lunch problem. Both are equally real parts of your profile.

Related Terms

Clinical Context

Spiky cognitive profiles are well-documented in ADHD, autism, and specific learning disabilities. The discrepancy between ability areas can itself be a diagnostic indicator—uniform profiles are more common in neurotypical populations.

Community Note

Understanding the spiky profile helps resolve one of the most frustrating experiences of neurodivergence: being believed about your strengths but not your struggles. The profile is one thing—peaks and valleys included—not two separate people.

Time blindness is the experience of having an unreliable internal clock. For many people with ADHD, time doesn't feel linear or predictable—it's elastic, inconsistent, and often invisible. You might genuinely not know whether something happened two days ago or two weeks ago, or consistently underestimate how long tasks take by 50% or more.

This isn't carelessness or poor planning (though it causes both). Research suggests that people with ADHD process time differently at a neurological level, particularly in the prefrontal cortex regions responsible for temporal processing. Time exists in two categories for many ADHD brains: "now" and "not now." If something is in the "not now" category, it functionally doesn't exist—which is why a deadline three weeks away feels imaginary until it's suddenly tomorrow.

Time blindness affects every area of life: chronic lateness, missed deadlines, difficulty estimating project timelines, forgetting to eat because hunger "wasn't registering," and poor planning for transitions. The most effective coping strategies involve externalizing time—making it visible through clocks, timers, alarms, and time-blocking.

In Practice

  • You're "just going to check one thing" before leaving for an appointment. Forty-five minutes later, you're running out the door in a panic, genuinely shocked at how much time passed.
  • Your boss asks how long a task will take. You confidently say "an hour." It takes four. This pattern repeats every single time and you can't seem to calibrate it.

Related Terms

Clinical Context

Research by Barkley (1997) and others has documented impaired time perception and temporal processing as a core feature of ADHD, linked to prefrontal cortex functioning.

Community Note

The term "time blindness" has been both celebrated and debated. Some people feel it perfectly captures their experience; others worry it sounds like an excuse. Most agree that naming the experience helps replace shame with strategy.

Tourette syndrome (TS) is a neurodevelopmental condition defined by the presence of both motor tics (involuntary movements like blinking, head jerking, or shoulder shrugging) and vocal tics (involuntary sounds like throat clearing, sniffing, or repeating words). Tics typically begin in childhood and can wax and wane in frequency and intensity throughout life.

The most common misconception about Tourette's is that it primarily involves involuntary swearing (coprolalia). In reality, coprolalia affects only about 10-15% of people with TS. Most people with Tourette's experience much subtler tics that may not be immediately obvious to others—but the internal experience of trying to suppress them can be exhausting.

Tourette's frequently co-occurs with ADHD (about 60% overlap) and OCD (about 50% overlap). Many people with TS describe tics as being preceded by a premonitory urge—an uncomfortable sensation that builds until the tic is performed, similar to the need to sneeze. Suppressing tics is possible briefly but requires significant mental effort, and the tics often come back stronger afterward.

In Practice

  • You spend an entire meeting suppressing your tics so colleagues won't notice. By the time it's over, you're mentally exhausted and the tics come flooding out the moment you're alone—more intense than if you'd just let them happen.
  • Someone sees your tic and asks "why do you keep doing that?" You've learned to say "it's a tic, it's involuntary" calmly, but the question still stings every time.

Commonly Confused With

Stimming

Stims are typically voluntary (though sometimes automatic) and serve a regulatory purpose—they feel good or helpful. Tics are involuntary and often unwanted. The key difference: stims are something you do for yourself; tics are something that happens to you.

Related Terms

Clinical Context

Tourette syndrome is classified in the DSM-5 as a tic disorder requiring both motor and vocal tics present for more than one year, with onset before age 18.

Community Note

The Tourette community has been working to shift public understanding beyond the coprolalia stereotype. Many people with TS say the hardest part isn't the tics themselves—it's other people's reactions to them.

Task initiation is exactly what it sounds like: the ability to start doing something. For most people, the gap between "I should do this" and actually doing it is small. For people with ADHD and other executive function differences, that gap can stretch into hours, days, or weeks—even for tasks they genuinely want to do.

The difficulty isn't about the task itself. A person with task initiation struggles can't start easy things either. The problem is neurological: the brain struggles to generate the activation energy needed to transition from "thinking about doing" to "doing." It's like having a car with a faulty ignition—the engine works fine once it turns over, but getting it started is unreliable.

Task initiation is closely related to ADHD paralysis, but it's more specific. While paralysis often involves overwhelm or too many options, task initiation difficulty can happen even when there's only one clear thing to do and no emotional barrier. The bridge between intention and action simply doesn't fire on demand.

In Practice

  • You need to send a two-sentence email. You've been meaning to send it for three days. There's nothing complicated about it. You just... can't start.
  • You finally sit down to work on a project and spend 45 minutes "preparing"—organizing your desk, refilling your water, adjusting your playlist—because the act of beginning the actual work feels like pushing through a wall.

Related Terms

Community Note

Many people find that external cues help: a timer starting, a body double beginning their work, or even just saying "I'm going to do this for two minutes." The trick is bypassing the initiation barrier, not overpowering it.

  • Smart but Scattered by Peg Dawson & Richard Guare (Book)

Twice-exceptional (often abbreviated 2e) describes people who are intellectually gifted while also having a learning disability, ADHD, autism, or another neurodivergent condition. The "twice" refers to being exceptional in two ways—exceptional ability and exceptional challenge.

The core problem with being 2e is masking in both directions. Giftedness can compensate for learning differences, making the disability invisible ("she's so smart, she can't have ADHD"). And the disability can mask giftedness, pulling performance down to average and hiding the exceptional ability underneath ("his grades are fine, he's not gifted"). The result is often a person who appears "average" but is actually working twice as hard to achieve that appearance.

This double-masking effect means 2e individuals are frequently identified as neither gifted nor disabled, falling through both sets of cracks. They often receive less support than someone with a visible disability and less challenge than someone with recognized giftedness—leading to frustration, underachievement, and a persistent feeling of "I know I can do better than this, but I can't figure out how."

In Practice

  • You scored in the 99th percentile on IQ tests but can't organize a binder, turn in homework on time, or follow a lecture without zoning out. People see the intelligence and assume the struggles are laziness. The ADHD is invisible behind the giftedness.
  • Your child reads at a 12th-grade level but can't handwrite a legible sentence. The school focuses on the writing problem and ignores the reading ability, or focuses on the reading ability and dismisses the writing problem. Neither gets addressed properly.

Related Terms

Clinical Context

Twice-exceptionality is recognized in gifted education literature but remains poorly addressed in clinical practice. Identification requires assessment of both giftedness and disability, which are rarely evaluated together.

Community Note

Many 2e adults describe a lifelong feeling of "impostor syndrome"—too smart for disability accommodations, too struggling for gifted programs, and never quite fitting the narrative of either. Finding the 2e label is often profoundly validating.

Tics are involuntary, rapid, repetitive movements or vocalizations. Motor tics include blinking, head jerking, shoulder shrugging, facial grimacing, or more complex sequences like touching objects or mimicking gestures. Vocal tics include throat clearing, sniffing, coughing, or more complex sounds like repeating words or phrases.

Tics are the defining feature of tic disorders, which the DSM-5 classifies under neurodevelopmental conditions. Tourette syndrome requires both motor and vocal tics lasting more than a year with onset before age 18. Other tic disorders involve either motor or vocal tics but not both. Tics typically begin in childhood between ages 5-7, often peak in early adolescence, and may lessen in adulthood—though many adults continue to experience them.

Most people with tics describe a premonitory urge—an uncomfortable sensation that builds before the tic, similar to the feeling before a sneeze. Suppressing tics is possible for short periods but takes enormous mental effort, and the tics often rebound more intensely afterward. This is why telling someone to "just stop" is both unhelpful and exhausting to hear.

In Practice

  • You suppress your tics through an entire job interview. You get the job, but you're so exhausted afterward that your tics are worse than usual for the rest of the day—the energy has to go somewhere.
  • Your child's tics get worse during exam week. A teacher thinks they're "doing it for attention." You explain that stress increases tic frequency—it's an involuntary response, not a choice.

Commonly Confused With

Stimming

Stims are typically voluntary and serve a regulatory purpose—they help you feel better. Tics are involuntary and often unwanted. A person who stims is doing something for themselves; a person who tics is experiencing something happening to them.

Habits

Habits are learned behaviors that can be consciously changed over time. Tics are neurologically driven and can't be stopped through willpower alone, though some therapies like CBIT can help manage them.

Related Terms

Clinical Context

The DSM-5 classifies tic disorders as neurodevelopmental motor disorders. Tourette syndrome, persistent tic disorder, and provisional tic disorder are the three primary diagnoses, distinguished by tic type, duration, and age of onset.

Community Note

Many people with tics say the hardest part isn't the tics themselves—it's the social pressure to suppress them. The relief of being in a space where you can tic freely, without judgment or staring, is something most people with tic disorders describe as transformative.

Time anxiety is the chronic sense that you don't have enough time—not for a specific deadline, but in general. It's the feeling that life is slipping away, that you're behind where you should be, and that the clock is always working against you. While anyone can experience time anxiety, it hits neurodivergent people especially hard because it layers on top of existing difficulties with time perception, executive function, and self-regulation.

For people with ADHD, time anxiety often compounds time blindness. You already can't feel time passing reliably, and the anxiety about that unreliability creates a feedback loop: you're anxious because you lose track of time, and the anxiety itself makes it harder to engage with the present moment. The result is a constant low-level dread that something is being forgotten, missed, or wasted.

Time anxiety is different from being busy or stressed about a deadline. It's an existential discomfort with your relationship to time itself. It shows up as compulsive clock-checking, guilt during rest, difficulty being present, and the nagging sense that no matter what you're doing, you should be doing something else. Recognizing it as a pattern—rather than a personal failure—is the first step toward a healthier relationship with time.

In Practice

  • You have a free Saturday with nothing planned. Instead of enjoying it, you spend the whole day anxious that you're "wasting" it—cycling through options, starting nothing, and ending the day feeling worse than if you'd been busy.
  • You finish a productive day at work but can't shake the feeling that you didn't do enough. You mentally replay everything you didn't get to, even though your output was objectively solid.

Commonly Confused With

Time blindness

Time blindness is a perceptual difference—difficulty sensing how much time has passed or will pass. Time anxiety is an emotional response—the dread and urgency that comes from feeling like time is always running out. They often co-occur but are distinct experiences.

Related Terms

Clinical Context

Time anxiety is not yet a formal clinical diagnosis, but it overlaps with generalized anxiety disorder, ADHD-related time perception deficits, and existential anxiety. Research on time perception and emotional regulation in ADHD provides the neurological backdrop.

Community Note

Chris Guillebeau, who is ADHD neurodivergent, wrote extensively about time anxiety in his book exploring how this pattern affects people across neurotypes—and how recognizing it can be the beginning of letting go of the illusion of urgency.

Task switching is the process of shifting your attention from one task to another. For everyone, there's a cognitive cost to switching—research calls it "switch cost" and measures it in reaction time and error rates. For neurodivergent people, particularly those with ADHD and autism, this cost is substantially higher.

ADHD brains struggle with task switching because disengaging from the current focus requires executive function that may be depleted or unreliable. If you're hyperfocused, switching feels physically painful. If you're in a state of paralysis, switching to a new task requires even more activation energy than starting from scratch. Autistic brains struggle because of monotropic attention patterns and the difficulty of state-change (autistic inertia).

The practical impact is enormous. Open-plan offices with constant interruptions, jobs that require frequent context-switching, and days with many short meetings separated by gaps too small for deep work—these are all environments optimized for brains that switch cheaply. For brains that don't, each switch costs time, energy, and quality.

In Practice

  • You finally achieve focus on a complex problem. A colleague taps your shoulder with a "quick question." The question takes thirty seconds. Getting back to your previous depth of focus takes thirty minutes.
  • Your calendar has meetings at 10, 11:30, and 2. The gaps between them look like free time. They're not—they're switch-cost recovery. By the time you've mentally transitioned from one meeting to the next, the gap is over.

Related Terms

Clinical Context

Research on task-switching costs is well-established in cognitive psychology. Monsell (2003) showed that switch costs are measurable even when the switch is predictable and prepared for. ADHD research has documented elevated switch costs in people with attention regulation differences.

Unmasking is the process of recognizing and gradually releasing the neurotypical performance that many neurodivergent people have maintained for years or decades. It's the companion concept to masking, and it often begins after diagnosis or self-identification when someone finally has language for what they've been doing.

Unmasking isn't a single decision—it's a gradual, often messy process. It might mean allowing yourself to stim in public, being honest about sensory needs, stopping the constant monitoring of your facial expressions, or simply admitting when you're overwhelmed instead of pushing through. Each of these changes can feel both liberating and terrifying.

The process isn't straightforward because masking served a purpose: social survival. Dropping the mask can mean real social consequences—confusion from people who "knew" a different version of you, workplace friction, or strained relationships. Many people unmask selectively, choosing safe contexts first and expanding slowly. There's no right pace or endpoint.

In Practice

  • After your diagnosis, you stop forcing eye contact in conversations. Some people don't notice. Others ask if something's wrong. You're learning to explain without apologizing.
  • You used to spend 30 minutes "getting ready" for phone calls—rehearsing what to say, preparing for every possible response. Now you let yourself say "I need a minute to think" when you need it, and the world doesn't end.

Related Terms

Community Note

Unmasking is often described as "meeting yourself for the first time." It can bring grief for the years spent performing, along with the joy of finally being authentic. Many people find that the relationships that survive unmasking become deeper and more genuine.

Universal design is the principle of creating things that work for as many people as possible without requiring adaptation or special accommodation. Curb cuts were designed for wheelchair users but benefit parents with strollers, delivery workers with carts, and travelers with rolling luggage. Captioned videos were designed for deaf viewers but help people watching in noisy environments, non-native speakers, and anyone scrolling with the sound off.

In the neurodivergent context, universal design means building workplaces, classrooms, and systems that accommodate cognitive diversity by default. Written agendas sent before meetings help everyone, but they're essential for people with ADHD or auditory processing differences. Flexible deadlines help everyone manage workload, but they're critical for people whose executive function fluctuates. Quiet spaces help everyone focus, but they're necessary for people with sensory processing differences.

The power of universal design is that it removes the disclosure requirement. When a building has ramps, nobody needs to "come out" as a wheelchair user to get inside. When a classroom offers multiple ways to demonstrate learning, nobody needs to disclose dyslexia to succeed. The accommodation is built into the system, not bolted on after someone asks.

In Practice

  • Your company switches to written project briefs instead of verbal-only assignments. Productivity goes up across the board—not just for the neurodivergent employees who were struggling, but for everyone who benefits from clarity.
  • A professor offers three ways to demonstrate course mastery: written exam, oral presentation, or project portfolio. Nobody needs to disclose a learning disability because the flexibility is available to everyone.

The neurodivergent community increasingly frames the goal as universal design rather than individual accommodation. Accommodation puts the burden on the person to disclose, request, and justify. Universal design puts the burden on the system to work for diverse brains from the start.

Working memory is the cognitive system that temporarily holds information so you can use it. It's what lets you remember a phone number long enough to dial it, follow multi-step instructions, or keep track of what you were saying mid-sentence. It's different from long-term memory—working memory is about what you can actively hold and process right now.

In ADHD, working memory capacity is often reduced. This doesn't mean you're less intelligent—it means your brain's "scratch pad" is smaller. You might walk into a room and forget why, lose track of a conversation mid-sentence, or need to re-read the same paragraph multiple times because the information doesn't stick during the first pass.

Working memory deficits also explain why verbal instructions can be so difficult for people with ADHD. By the time someone finishes a three-step instruction, the first step has already evaporated. This is why written instructions, checklists, and external memory aids aren't crutches—they're accommodations for a genuine neurological difference.

In Practice

  • Someone gives you directions: "Go left at the light, then right at the gas station, then left again after the school." By the time they finish, you remember there was a left turn involved. That's it.
  • You're composing a thought mid-conversation. Someone interrupts. Your thought is gone—completely. Not hiding, not on the tip of your tongue. Just erased.

Clinical Context

Working memory deficits in ADHD are well-documented, with research showing reduced capacity in both verbal and visuospatial working memory systems (Kasper et al., 2012).

Waiting mode is what happens when you have an appointment at 3 PM and your entire morning becomes unusable. You know you have hours of free time. You have a list of things you could do. But your brain won't engage with any of them because it's locked onto the upcoming event, monitoring the clock, afraid of losing track of time and being late.

This isn't laziness or poor time management. It's a collision between time blindness and executive dysfunction. ADHD brains struggle to feel the passage of time, which makes it genuinely hard to trust yourself to transition smoothly from one activity to another. Your brain's solution is to stop everything and wait—because starting something risks losing track of time and missing the appointment.

The result is entire days consumed by a single one-hour event. Many people with ADHD describe scheduling a morning appointment as "ruining the whole day" because nothing else gets done before or after it. The mental energy spent monitoring the clock is exhausting, even though from the outside it looks like you're doing nothing.

In Practice

  • You have a dentist appointment at 2 PM. It's 9 AM. You could do laundry, clean the kitchen, respond to emails. Instead, you sit on the couch refreshing social media because your brain is stuck in "waiting for the dentist" mode.
  • You stop scheduling afternoon meetings because every time you do, the entire morning evaporates. You've learned that an empty calendar is more productive than a lightly-scheduled one.

Waiting mode resonated so widely when it went viral that many people cite it as the moment they realized they might have ADHD. The experience is so specific and so universal among ADHD brains that hearing it described feels like being seen for the first time.

Workplace accommodations are the concrete changes that translate the legal concept of "reasonable accommodations" into everyday reality. They're the specific adjustments to environment, schedule, communication, or process that allow a neurodivergent employee to do their best work.

Common accommodations include noise-canceling headphones or a quiet workspace for sensory management; flexible scheduling or remote work for people whose energy and focus fluctuate; written instructions and agendas instead of verbal-only communication; regular check-ins instead of annual reviews; permission to use fidget tools or take movement breaks; and adjusted lighting to reduce sensory stress.

The challenge isn't usually the accommodation itself—most are simple and inexpensive. The challenge is the culture around requesting them. Many neurodivergent employees don't ask because they fear being seen as high-maintenance, not a team player, or less capable. Others don't know they can ask, or don't have the diagnosis they believe is required. Creating a workplace where accommodations are normalized—not exceptional—benefits everyone, not just neurodivergent employees.

In Practice

  • You ask for noise-canceling headphones and your manager says yes immediately. You're shocked—you spent weeks agonizing over the request, expecting resistance. The accommodation cost $50 and doubled your productivity.
  • Your company switches to an asynchronous communication model: discussions happen in writing, meetings are optional, and nobody is expected to respond instantly. Neurodivergent employees thrive—but so does everyone else who needed time to think before responding.

The most effective accommodations are often the simplest. The hard part isn't the accommodation—it's the system that makes you prove you're broken enough to deserve it. The movement toward universal design is about making these adjustments available without requiring anyone to justify their brain.

The Wall of Awful is a concept developed by ADHD coach Brendan Mahan to describe the emotional barrier that stands between a person with ADHD and a task they need to complete. It's not the task itself that's the problem—it's the accumulated emotional weight of every previous failure, criticism, and shame experience connected to similar tasks.

Every time you tried to clean your apartment and couldn't finish, a brick was added to the wall. Every time a teacher said "you're so smart, if you'd just apply yourself," another brick. Every missed deadline, every disappointed look, every time you promised yourself "this time will be different" and it wasn't—each experience adds to a wall that must be climbed before the task can even begin.

This explains why some tasks feel disproportionately difficult. Writing an email isn't hard. But writing an email when your Wall of Awful includes every email you forgot to send, every response you agonized over, and every time someone was upset by your delayed reply—that email becomes a mountain. The task hasn't changed; the emotional barrier in front of it has grown.

In Practice

  • You need to call your dentist to schedule an appointment. It's a two-minute phone call. But you've missed two previous appointments, you feel guilty about your dental hygiene, and the last receptionist was visibly annoyed. The Wall of Awful around this call is enormous.
  • You sit down to write a report and immediately feel a wave of dread that has nothing to do with this specific report. It's the accumulated shame of every report you turned in late, every one that wasn't good enough, every time writing felt like proof of your failure.

Brendan Mahan's Wall of Awful concept has become one of the most widely shared ADHD frameworks because it names the invisible barrier that no productivity hack addresses. You can't organize your way over the wall—you have to process the emotions it's built from.
