My 90 year old mum was diagnosed with Alzheimer's and vascular dementia 18 months ago and has been in a care home, a couple of miles from me, ever since. Mum is immobile and rarely leaves her room. She settled pretty well but is deteriorating lately, and keeps saying she wants to 'go home'. I can understand that ' home' might be her way of seeking a feeling of safety but I don't know what is the most comforting thing to say to her. Sometimes I find myself saying 'you are at home, mum' but it has no effect. Any suggestions?
