Lithium made such a difference in our Autistic son, I asked the Dr about our other son, because they both have the same bio-mo who IS bipolar, and he has been on it for less than a week, and we see such a difference already. I have to admit that he was also upped on Depakote and so was the Buspiron and Abilify - the change is night and day, but, BUT, he is on spring break right now so we will find out just how effective everything is when he gets back to school.
Our son had a very bad habbit of getting up at night to steal food. He was also recently given Seroquel and in reviewing our camera feed (placed to catch him in the act, etc), he has not been getting up to get food, and we do not have any difficulty getting him up, which is a major plus.
I'm hoping to find a mix that works and can start decreasing the amounts, but still keeps him from the sexual acting out, the assaulting other people and the explosiveness (which really diminished after Zoloft was discontinued). I always suspected Zoloft was what made him so dramatic with the tantrums, and removing it proved that he was bipolar, because anti-depressants normally cause rage in bipolar people....and I can verify that it really does.
He is getting along so well with his sister, right now, that both my husband and I find it unsettling. It went from constant fighting to thick as thieves - no middle ground. Id much rather have this than anything in the past, though.
