my brother has asperger's syndrome as the doctor said. He's not talking anymore starting age 16, he was a different person then like once he used to be normal before reaching such age. What alarms me now is that since he can't talk he's not able to express whatever he feels instead esp. when he gets tired he had like these hallucinations- eyes wandering everywhere, wouldn't eat at times, restless, and esp. his muscles stiffen. What do i do with his muscle stiffening??and also when he gets confused or felt sick at times he would just go violent and punch anything or anyone he sees, maybe it's because he wasn't able to express what he feels. what to do??
