Mom's dementia has advanced fast. She now needs 24/7 caregivers to be sure she is safe because she forgets where she is (at home) and hear noises. The challenge is that I think all is fine and then she calls and asks me something we talked about 2 hours before or a day before. The caregivers tell her what has happened but she doesn't believe them. Sometimes she doesn't believe me. I have been saying you just forgot. How else can I phrase something so that she can understand that what she thinks isn't real? Or is that possibility gone? And if so, what is the best comeback?
