Anxiety: Meaning and Examples — NeuroDiversion

Neurodivergent glossary

Anxiety

A persistent state of worry, dread, or physiological tension—extremely common alongside ADHD and autism, where it often looks different from textbook descriptions.

What it means

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.

What this can look like

  • 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.

Useful distinctions

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.

Context

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.
