we tried Risperadal briefly, we saw an increase in his motor tics on that and we were also worried about the long term side effects since he is only 6 years old. We may have to go back to that. We just started medications in the last 6 months. We are so desperate to get some type of consistant behavior out of the 6 year old. When he tantrums, the 3 year old with autism copies his behaviors and tantrums too (seriously, every time), it can be a three ring circle here. 
I think I would be open for higher doses of lamectal, however I really want a new eeg... he looks like his seizure activity is increasing on these medications. ??
