Big time lurker here :). My D just graduated and, like many of your kids, will be heading off to college in fall.
She is a bright girl who tests well but struggled scholastically because she doesn't turn things in. Most of the time the work got done but not submitted. Near the end of the school year she started saying some things that led us to having her evaluated for depression. At that time, the crisis therapist she saw said that she believed that D might be ADD (no hyperactivity) and that we should have her evaluated and see if ADD treatment might help with the depression (kind of a chicken/egg thing--Is she depressed because of the ADD or is the ADD a symptom of depression).
To make my story slightly shorter, she has been on an ADD med for about 6 weeks and will be continuing on it for the foreseeable future. Is this something that should be disclosed to her school?
She had no accommodations (IEP or 504) in school because she was diagnosed so late and I'm not sure whether there would even BE accommodations at the college level.
