Another resource you might want to look at is "Misdiagnosis and Dual Diagnosis of Gifted Children and Adults". See link: http://www.amazon.com/Misdiagnosis-...mp;s=books&qid=1243387127&sr=8-1

This is an excellent read and may help you see whether your child really has these diagnoses -- or whether he is just gifted. It doesn't really help you in dealing with the specific behavioural issues, but it does help you to recognize those traits which are a function of simply being gifted, as opposed to some (other) disorder.
