People often ask about the “types of autism” — but the answer has changed. Autism is now understood as a single spectrum rather than a set of separate types. Here’s what that means and where the old labels went.
One spectrum, not separate types
The current diagnostic manual (DSM-5) uses one diagnosis: autism spectrum disorder (ASD). Previously separate diagnoses — including autistic disorder, Asperger’s syndrome and PDD-NOS — were combined into this single spectrum in 2013, because research showed they weren’t cleanly distinct conditions.
“Spectrum” doesn’t mean a straight line from “a little autistic” to “very autistic.” It means autism varies across many dimensions — social communication, sensory experience, need for routine, language, and more — so no two autistic people are the same.
What happened to Asperger’s?
“Asperger’s syndrome” was folded into autism spectrum disorder. People previously diagnosed with Asperger’s are now considered autistic, often with lower support needs. Many still identify with the term, though it’s no longer used diagnostically.
How autism is described now
Instead of “types,” clinicians describe:
- Support levels (1, 2 or 3) reflecting how much support a person needs — see autism levels explained.
- Profiles such as PDA (pathological demand avoidance), which capture particular patterns within the spectrum.
- Co-occurring conditions, like ADHD (see AuDHD), anxiety or intellectual disability.
Why this matters
Understanding autism as a spectrum shifts the focus from labels to the individual — their specific strengths, challenges and support needs. A thorough autism assessment does exactly that. Read autism in adults or book an appointment with a referral.
