Love all of the APs (Abilify, Geodon, Zyprexa, Risperdal, Seroquel, etc). They can help the aggression when nothing else has touched it. And, at least in our case, once the aggression was under medical-control, we were able to get a lot of therapy done with calming techniques, social skills, language, etc and then wean off the APs and the aggression did not return. We did have some of the side-effects (weight gain, lactation, tics, etc) but they were worth it. Amazing medications, simply amazing.
