Father diagnosed with vascular dementia with paranoia. He refuses to sign a POA saying it gives me too much power. I know that I'm going to have to file for guardianship, (he says he will kill himself when I do this). If something happens before the process is completed and he's unable to make a decision then who will make the decision? Several years ago my FIL was unable to make a decision about care after being hospitalized with nothing in place and the doctor refused to discharge him to anywhere but a nursing home. Am I looking at the same situation again?
