i have some questions. my wifes grandfather has parkinsons. they have him on medication, but nothing they do seems to help. he was just in the hospital for observation. they changed his meds and were watching to make sure he takes them. well, he fell asleep and missed his last dose. he didn't shake for 2 days after that. the doctors can't say why. i was wondering if this is a normal thing with parinsons. also do to this the family is doubting that it is parkinson's. he is a vietnam vet. he worked as a nurse so he was exposed to all sorts of things includeing agent orange and the like. the family thinks that it maybe this. i however haven't found anything supporting this. if someone can help me out with some answers or send me in the right direction to find them i would greatly appreciate it.

thanks.
