Has he been evaluated beyond a neurologist?
Stimulants can make any child mean and aggressive. You will know pretty fast if it works or not. Stims work or don't work right away. They do not have to accumulate like other psychiatric medications. Doesn't your school offer Occupational Therapist (OT) for free? Does your child have an IEP? I am assuming you live in the US.
Glad there was progress. A pity to have to discontinue the Occupational Therapist (OT) now.
