DS9 could have probably been labeled ODD before he got treatment (meds & therapy) for his PDD-NOS (and ADHD & anxiety.)
We got him on Risperdone (the only medication approved for treatment of ASDs, btw) and Intuniv (non-stimulent ADHD med - ASD kids often have problems with stimulents) and he is like a different child. That along with therapy and a better school situation has been like magic for him.
I strongly recommend an eval by a neuropsychologist. Also, stimulents can make anxiety worse, so you might want to look at trying a non-stimulent med for the ADHD. There are several available now.
