My son was originally diagnosed ADHD, and aspergers later. I think the ADHD is still true for him. If anything, before we started him on concerta, the hyperactivity masked any other issues.
He still takes the concerta, it really helps him focus. I find that he is beginning to be able to slow down and think social situations through, I don't think he'd be able to do that without the ADHD meds. He is also on risperidone, but that came later. He was prone to some scary fits of rage, he still can fly off the handle, but it's not nearly as scary!
