Be aware also that the disabilities office is sometimes not the source of most of the support. They often serve more as a filter for requests, and I have seen them referred to as “the guarddog of the curriculum.” Accommodations cannot change the curriculum, or pose an undue burden financially or administratively.
In our experience, deans are the most helpful. Deans will communicate with MD’s and therapists and then tell the professors that they need to accommodate. But most professors are supportive.
The disabilities office just registers you, and gives the student letters to give to professors. It is up to the student to advocate for themselves, and deans and advisors can help with that.
I think it is really hard to get real info before acceptance and even then expect the first year to be a time of learning the ropes.
