Diagnostic and Statistical Manual of Mental Disorders IV

The DS- the DSM.

You get through the DSM-4.

[laughs]

All the, all the people with diagnosable mental conditions, and then...

going back to the foundational case studies that they used from the 1940s.

That shaped even the most recent DSM-3 and DSM-4, which is the diagnostic manual, and they were constructed from almost exclusively male population research.

A recent academic review has put it plainly.

Basically, the incidental gap is a structural bias, and it's baked into how autism itself came to be defined.

I think, and you're challenging me now to remember, I think it was DSM-3 that it went in as a diagnosis, as a standalone diagnosis.

DSM-4...

It then changed again.

So you had Asperger's and things added in DSM-IV as a standalone diagnosis.
