ADHD and ASD go hand in hand. Not all ASD people have ADHD, but if someone’s on the spectrum, ADHD might want to be looked at if they’re having issues that are similar.

eh, kind of hit or miss with autistic people, afaik.

hyperfocus is a big thing for autists, which is a problem with attention, since it keeps you from choosing what you want to focus on.

so if you've got an assignment due, and your brain decides we're gonna focus on [different thing] right now, possibly for days on end, that can be a serious problem.

it can also look basically identical to ADHD for outside observers, since the result is often the same "they didn't to [the thing]!"...

and that then gets mistaken for a lack of motivation, which it isn't really:

it's a lack of ability to choose what to be motivated about.

it's one of the reasons that there's so much overlap in diagnosis of ADHD and ASD: symptoms can present very similarly to outside observers
