My nephew is 16 years old. He has almost no verbal communication skills. He has been diagnosed with Autism, PDD, oppositional definat disorder, and a few other things I'm not sure of. Our problem is he is 16 years old and looks like a linebacker. He has always had tantrums and "pitched fits", but now he is pushing his mother down, putting his fist through sheetrock walls, beating on the cars, hitting his 72 year old grandfather, throwing things, etc. This happens any time he doesn't get exactly what he wants when he wants it. My parents spend a lot of time with him and I have grown concerned that my nephew will hurt them in one of these fits. We don't know where to get any help. He's on several medications, etc, but nothing is helping and this is just getting worse. We had a terrible scene last night and he screams at the top of his lungs, kicked doors, knocked over lamps, beat on three different vehicles, pushed his mother about five feet across the room, hit his grandfather, dented the wall in his bedroom, and the list goes on. Has anyone else had these experiences and can anyone point us in a clear direction? We are at our wits end. I'm afraid we are going to have to find a facility that can care for him if we don't get a handle on this. His doctor says we just have to hang on until he grows up. Help please.
