My son has ADHD, Obsessive Compulsive Disorder and Asperger Syndrome. It would be very hard for me to pick out which behavior is from which disorder but many of things you describe sounds like my son did. We had him evaluated by a Psychiatrist who diagnosed him at the age of five, he is now 12. He is on Adderall and clonidine. The adderall is for the ADHD and the clonidine just helps to calm him...get his thought together and be able to sleep at night. I hope this helps.
