Many accommodations are based on situations. In my case, I was undergoing trauma therapy while recovering from a concussion and the mental hell that comes from sexual assault. Why would my employer or future employers need to know that? 
Accommodations are typically short-term and used to help students succeed when the cards are all of a sudden stacked against them. These students are not stupid, incompetent, or unable to function; which is what you seem to be assuming. It takes great strength of character to admit you need help ​and to ask for it.
