My 90 year old cousin has dementia. He was diagnosed about 4 years ago. He's lived alone for the past 30 years. He hasn't bathed in at least a year, doesn't eat well, won't flush the toilet, has serious incontinence issues and is missing his front teeth. He refuses to go to the doctor and refuses to leave the house. POA won't work since it states that I need a doctors letter stating that he is incapable of taking care of himself. Is there a government agency I can call to do a home visit to get him help or into a nursing home? He shouldn't be living alone and I'm at a loss as to what to do for him.
