Hi all, I have been a lurker for a little while, but now it is time to come out of the shadows, I guess, as we could really use some help. I am putting background in black, and questions in red, so skimmers can get right to the point. I think this will be a long post. He is 13 years old, 7th grade, diagnosed at age 5 ( by public school) with Asperger's. He is currently in the adolescent psychiatric unit. We found out on Saturday that over the past two years, he has killed three hamsters and a guinea pig .. all at friends' homes. No remorse whatsoever, except for the fact that he got caught and his life is now different. On Sunday, he told us that he wanted to stab himself with a knife, and told us that he had attempted this previously. This was all news to us. We went into the ER on Sunday and he was admitted that night. He also developed public masturbation two years ago, which we tried dealing with through therapy, and with a plan at his school, which is a Special Education private school. He lies constantly. Other than those things, no fights or violence toward other people, and no drugs, or face-to-face defiance. His psychiatrist at the hospital talked of conduct disorder, sociopathy, etc... and suggested that the autism might be misdiagnosed. On the same day we talked about sociopathy, we got his test results from standardized testing at his school from last year 6th grade, and he is now working at around a second grade level! This, also, was a shock, since he was low before, but never that low. Here is what our plan is : We really need expert testing, on a comprehensive scale. I am thinking, neuropsychological, educational, and a good psychiatric diagnosis by someone who is expert in differential considerations. We may have multiple problems, as he has never really seemed 100% Asperger's to me, he is nearly impossible to teach or correct (rewards, restrictions, grounding, spanking, visual schedules or charts, role-playing, etc...). He had a cyanotic episode at birth and I have long suspected brain damage somewhere but can't seem to get anyone on board with me. The hospital psychiatrist put him on 100 mg of Zoloft because he says it might help with his impulses. After some research, that seems like a high dose, plus I am worried about side effects. Should I question this medication and dosage? He also called yesterday and said he feels wonderful on the drug, and has no desire to kill animals or harm himself -- after two doses. Hmmm....either placebo, mania, he is trying to say what he thinks will get him out of the hospital, or his brain is so serotonin starved that it is actually working within in two days. Does this sound familiar to anyone? Anyone have anything to offer. We are pretty broken up right now. Thank you.
