Thorazine (chlorpromazine) is a typical antipsychotic. It works by lowering dopamine (a neurotransmitter assoicated with "want," too much of which can cause psychosis and too little of which can cause depression and lack of normal drives). Side-effects include TD, which consists of tics that stop only when you sleep, as well as tiredness and mental fog. The general consensus is antipsychotics are useless for "treating" autism, but are useful for making otherwise annoying children quiet and sedate ("quiet and sedate" as in "can not muster up the energy to care"). This is done for selfish parents who don't care about their children's well-being, and desperate parents who think autism is like cancer. (Actually, I hate that analogy. Cancer's treatable and generally not very dangerous. A better analogy would be "autism is like terminal cancer that's metastasized to every part of your body." Well, it would be if there were any truth to what the curebies think.)
crazymeds.us has information, and the best part is, they somehow don't get sidetracked complaining that cancer is a bad analogy because it's not bad enough.
