My father is 86, lives alone and has dementia. We alerted his physician approximately 9 months ago about our concerns, I have 4 other siblings. His doctor did a mini mental evaluation and I was told that he was diagnosed with forgetfulness possibly early stages of dementia. He had recently lost his long time girlfriend and we thought he was simply depressed. He has continued to decline over the past 4 months. He stopped showering and providing basic self care, shaving and wearing clean cloths. He is non compliant with his medication and not cooking for himself. He is not eating. He has lost significant weight, stopped paying bills, forgetting doctors appointments, unable to determine time of day or day of the week. He still is calling his deceased girlfriends number daily, several times daily and has to be reminded she passed almost a year ago. He believes she has another boyfriend. He will sit and stare at the tv/ VCR, frozen screen because he can’t figure out he needs to hit play. His mail has piled up, insurance has lapsed due to non payment. He thinks someone occasionally lives at his home and states he wakes them in the morning occasionally. He has spoiled and expired food in his refrigerator, eggs that expired 3 months ago but will not let us throw it out. He becomes paranoid and somewhat nasty when we try to help often snapping and becoming sarcastic and hurtful. I am a nurse and I live the closest to him so I am most often involved. I have repeatedly called his Dr’s office and explained my concerns but seem to be getting nowhere. I have asked for a dementia diagnosis so that we can help in decision making for him. He missed his most recent appt and will not answer the phone to reschedule. He still drives. I am his health care surrogate and my brother is power of attorney upon my fathers inability to make sound decisions for himself. We currently are building an efficiency apartment at our home for him , he does not know. Please tell me what I can do to help my father. How we can approach him. How we can legally help him with his personal affairs. Thank you.
