Well, that's also a technicality. The DSM-V does not recognize comorbidity of ASD and ADHD - if you have ASD you can't have ADHD.

It might just be that the DSM-V is wrong and that those people have both ASD and ADHD

The DSM V does recognize comorbidity of ASD and ADHD and allows for simultaneous diagnosis. You might be thinking of the DSM IV which didn't.

You're correct, my bad for the typo. In any case that does partially explain the issue.

Fake news..

This is largely taxonomy. Both ADHD and ASD are very loose diagnoses, not specific testable measurements. Response to medication can differentiate to some extent, but the label doesn't really mean anything when you consider both diagnosis are based on observing symptoms/presentations, not predicting symptoms/presentations.

it's definitely wrong. The DSM V was a big step backwards and it was not great beforehand. it essentially a diagnosis for whatever you want lol

>The DSM-V does not recognize comorbidity of ASD and ADHD - if you have ASD you can't have ADHD.

That's wrong.

>if you have ASD you can't have ADHD

Not only you can, but it's a very common diagnosis.

As said later, this was an error (I can't edit the comment anymore) - that was true in the DSM-IV.
