National Center on Elder Abuse This was going to be my suggestion. My 91-year-old grandmother was living with my alcoholic mother when the doctor finally called social services and they arranged to have my grandmother moved to my aunt's house. They wouldn't see her stay another day with AM, and made sure all of her medical care was moved and everything was set up. Truly wonderful people who put the welfare of the elderly first.
