Dunno about anything else, but I have Aspergers, and the only way I can think of really simulating that is giving disadvantage on basically anything that needs a Charisma check.
If you're the kind of autist that is good at stuff they're interested in you're like a wild magic sorcerer of every day tasks or something.
I have a very good memory and I learn quickly, so there's some bonuses to lore checks on certain subjects.
