ADHD and ODD

My son is 5 years old and is in kindergarten. He has had a tough year at school and we have tried alot of different medicines but they seem to help his ADHD but makes his ODD worst. He is currently taking Metadate cd 20 mg and he still has defiant and agressive problems. We have tried alot of the stimulates and they all seems to have the same effects. Should we move on to Risperdal or abilify? Or maybe try clondine? Can you help?

ODD is one of the anxiety disorders.  Often anxiety disorders appear as ADHD/ADD when, in fact, it is the extreme stress from anxiety which causes these behaviours.  I'm wondering if that is the issue here - you're treating the wrong disorder.  What would happen if the ODD were treated (anxiety disorders are usually treated with SSRI medications)?  Would the ODD as well as the hyperactive behaviours decrease?  Of course, this is only a supposition but one worth discussing with your family doctor.
