My mother is in a assisted living apartment. She has three daughters we talk to her every day see her quite often, bring her food etc. She is always having her worst day saying pain so bad she just can't live another day. She calls doctors makes appointments, goes to ER, will call us many times a day wanting something done to help her. Doctors always find nothing wrong. Can this be a form of DEMENTIA? She is driving us crazy, and spending a lot on medical treatment.
