My DS8 and I have just gone through this. He has been diagnosed with Tourette's Syndrome, which is more than just the outward tics, it has components of OCD and ADD. We are not medicating but are writing an IEP next week to accomadate his classroom needs. I will say that having this dx has made the teachers lighten up and give him some room. It also lets me know that he isn't just trying to drive me nuts. Before the dx it was suggested as aspergers, add, ocd, opp/def and everyother group of letters. We were fortunate to see Dr. Amend in Kentucky to review our records and he agreed with all this. I would have never thought of Tourette's due to my own preconcieved ideas but looking back it is now obvious, there I just put one more possibility in your basket sorry
