Neurodivergent glossary
Neurodiversity
The biological reality that human brains are wired in many different ways—a framework that treats neurological differences as natural variation, not pathology.
What it means
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
What this can look like
- 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.
Often confused with
Useful distinctions
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.
Context
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.
