If you haven't, watch Azumanga Daioh.
Do you think that Osaka-san (Ayumu Kasuga)could have AS?
There are a lot of signs pointing that way, which you should have noticed if you watched the series.
She's "slow", daydreaming, vivid visual imagination, is good at non sequiturs, puns, word plays and riddles, bad at physical endeavors, live in her own world, is a bit morbid, she sees obvious things that others don't, and she has got a surprising lot of knowledge about marine biology (especially sea slugs) and obscure kanji.
She have also mentioned that being around a lot of persons makes her tired.
Don't know if all of these are specifically AS traits, but they match my personality quite well.
What do you think?
