Mom's health require for her to be in a care facility. She has not been left alone for over 3 years. She recently spent 2 weeks in hospital, then was transferred to Hospice. She got better and was transferred to a care facility. She thinks she is in rehabilitation place. Should we tell her she has dementia? She is getting very impatient and says she is going home. Physically she is better but it would not be safe for her to go home alone.
