Researches have found that not all ADHD kids who show signs of aggressive behavior might not need antipyschotic meds: http://www.ivillage.com/aggressive-kids-adhd-may-not-need-antipsychotic-meds/4-a-278742?ice=iv:mb:msg:mm [2].
I like the overall message of the article to not give up after trying one med, that it is a trial and error process.
