some evidence for neurodivergence (in this case autism spectrum disorder) for Gould
"some evidence", indeed. Carefully formulated, but I think it's pretty obvious that he was firmly 'on the spectrum'. Of course, something like that is always a bit of a haphazard comment to make due to the diagnostic and ethical problems associated with applying labels to people.
Asperger's Syndrome was added to the DCM.
Asperger's is no longer in the DSM; it was removed in V. It was still there in DSMIV but I think this was deemed problematic for two reasons:
1: It suggested conceptually distinctness between autism as such and Asperger's, whereas in reality the criteria and phenomenology overlap considerably.
2: In relation to the above, having Asperger's as a distinct category implies a certain homogeneity within the broader autism spectrum that in reality turns out to be difficult to uphold.
As a result, this was all replaced by a single 'autism spectrum'.
Were any similar cues available for HCB?
I wouldn't know, but based on what I do know about HCB, it's not something that comes to mind.
