What is your experience with using Abilify (aripiprazole) to help their asperger's syndrome?

Depends. Abilify (aripiprazole) is not a treatment for as, but it sometimes is quite helpful for reducing irritability, rigidity, and perseverative behaviors, all of which can make life more difficult for the individual and others. It is not a medication to be used lightly, but it can make an enormous difference in the life of some people with as, depending on what problems they are having.
Aspergers. With irritability, low tolerance for frustration, and excessive rigidity I have seen Abilify (aripiprazole) do some very good things. Consult a board certified psychiatrist for more info. http://www.youtube.com/watch?v=xg1ngp1ngds.
