herbal replacement for risperdal

Hi all, My boy(23) has DS and was taking Risperdal to keep him more focused. It was effective in helping him to be more independent (shower,dress himself, etc.). we had to stop giving it to him because he was having side effects. Does anyone know if there is a herbal replacement for Risperdal? Or if there is a doctor that specializes in DS that uses natural remidies? Thank you. Tweet
