My mother made inappropriate calls and the phone issue was a tough one. She also called me up to 37 times a day. She was attached to the cell phone and when I took that and showed her the assisted living landline, she used that less.

In her facility, the calls your mother is making would mean memory care.

Hospice is very helpful for dementia. It is a legitimate hospice diagnosis and doesn't mean death is imminent. My mother was off and on for 3 years at least. You get a nurse, aide, social worker, chaplain, volunteer. I figured the more company for her, the better. (I was there daily too.) Hospice has a lot of medications and doctors and nurses who are experienced in this kind of behavior.
