I'm worried about my son who is nearly 16. He has an AS diagnosis and takes meds for OCD. But lately he talks out loud to himself--or just blurts out random stuff while sitting at his computer,playing a computer game. Sometimes I listen to him from the next room. In a period of 30 minutes he talks in a Cockney accent, saying "I've got a tiny penis" over and over again, "I like to poop" in a high-pitched voice, then some wild giggling. Then he might be quiet for 20 minutes, and then out of nowhere, he will do a low, growling voice that sounds like he is trying to be a monster. If I walk into his room and ask him if everything is OK, he snaps out of it, and says "I'm just bored."
Then he might go for a whole week without any of this behavior, and it will start again.
He stays in his room most of the time, he is becoming more dependent on me, like he's regressing, and he is losing some cognitive ability at school. He is in an independent study program in high school because he became very anxious last year about school. In fact, he does almost no school work at all anymore--he expects me to do most of it for him. If I try to focus him on it he calls me nasty names, like "c$nt" and "whore."
Is this schizophrenia? I'm so worried, but don't want to over-react either.
