I've been thinking and I concluded that she doesn't have any disability, but does have brain cancer.
It's not only about the symptons in themselves. It's about why they're there. You see, it's funny because Shizune's path is all about A22 telling us there is something wrong with her but not saying what exatcly it is.
It's all a joke the devs played on us, quite like that one about the principal being a professional wrestler. Anyway~! Let's see our evidences that the devs didn't tell us everything:
a) She's the only one who gets sick for no plotwise reason.
Sure, Emi and Rin also do get sick, but it's all for a reason that makes the story advance somehow. Emi's cold is preceded by one of the most important decisions in her route (actually it doesn't make much of a difference, but it's one of the decisions that have to do with the path's main idea the most) and succeeded by her first H-scene. Rin's illness is very alike, except it's just a kiss.. Misha's ailment after the parfait scene doesn't quite lead to Hisao getting closer to Shizune in any way, as far as I can remember and Shizune even tells him there has been more of it. For no particular reason.
b) She's a character with really, really uncommon personal traits.
Whereas the main girls where carefully built in order to avoid stereotypes. Misha is the one whose personality is the furthest from a real, or at least a common person. Either she's some kind of mockery at a particular trope (and then a physiological cause would be perfect for this kind of internal joke) or she's not, but then again it doesn't seem like her weird sleeping habits or her inability to spot Jigoro's - or anyone's - hostility were just there. And don't forget that all of these details were lampshaded, but didn't serve any literary purpose. And I don't think charisma was the aim here, even though it did make me like her even more.
c) They had a professional medical consultant
Or something like that. Aura dixit. This means that they weren't even intending to miss a trick. It's as if everything said and stated has a reason to be so, particularly about medical issues. They wouldn't want to lay out a handful of weird behaviours and say it's a coincidence when asked about it. And, even then, that would make it just another trick. Because that's what they would have wanted us to think. Either way, it's not aimless.
EDIT: In-game, of course, no one knows about it.

While we are here discussing, Hanako is somewhere hopping from dark to darker tiles. Alone.
