My father has advanced P.D. He is not on any medicine because he is elderly, has cancer, etc. and has dementia. Drs. thought the side effects would be too much for him. My question is: He has lost all control of his bodily functions. Now he says he doesn't even know when he has soiled himself or wet himself. Is that possible? Or is it his dementia? He has good days and bad days and some days he can carry on a perfectly normal conversation, so it is hard to believe that this could be dementia. Anyone have any experience with this? I dont know how you could not know this!
