My father has three children. He has always stated that he does not want son 2 to have decision making over his health or finances. Son 2 lives closest. Father becomes confused, is hospitalized, recovers and has mild dementia. Son 2 has POA. Father doesn't remember how this happened or when and does not want son 2 in charge. Son 2 will not allow information to other sons. Places father in lock down memory unit. Father does not want this situation. Father can clearly indicate consistently that he doesn't want Son 2 as POA. Son 2 will not allow father to be taken for eval to his PCP. Son 2 will not allow access to records. Son 2 will not talk on phone to siblings. Advice?
