My Dad has Parkinson's disease. He lived by himself, but he is right next door to me. He has not bathed in over a year. He doesn't leave the house, open a window, or anything. All he eats is junk food. He will not bathe, even when offered help, or a shower chair. He won't even wash up! He changes his clothing once a month if even then. He has crusty peeling skin all over. He continually gets pink eye from not being clean. My most recent concern is that his feet are a purplish color. I told him to speak to his doctor about it, and he refuses. I know having him checked for depression will be a suggestion, but he is so stubborn that he would never allow it. I am concerned for his health and well being, but what can I do if he won' do anything or let me help him.
