My younger brother was diagnosed with ADHD when he was about 6 and epilepsy (absence seizures) at age 8. He is on concerta for ADHD and depakote for epilepsy they change his doses constantly. He has always had strange behavior issues that shock me and mostly everyone but my mother. I am the oldest child and also have a younger sister that is normal. No child is perfect obviously and I can understand bad behavior but the things I am seeing with my brother is severely disturbing.The strangest thing about his behavior is complete disregard to anyone and anything. He listens to nobody is extremely manic and talks to himself. He absolutely cannot remain quiet for any period of time. He clicks and whistles and makes strange throat noises compulsively. He is also extremely overweight. Now that he is getting older and soon going into middle school these things are becoming more and more disturbing to me because I see other kids his age acting nothing like him and well with him looking like a mental patient im worried about ridicule from peers and even worse progress in school (hes always had horrible progress in school). The worse thing is neither of his medications seems to be helping with either of his conditions and hes on a stronger epilepsy medication than I am and I have grand mal or whatever they call them now. I guess what im getting to is does this seem at all normal? Should I suggest to my mom that he see a psychiatrist?
