My grandmother is almost blind and since last year when she broke her femur she and my grandfather have a 24 hour caretaker living with them. Recently, she started to think that she is not in her flat. My mother and I speculate that she remembers that 30 years ago she was living in a big house which they had to sell then.
In about a month a neurologist will come to see her but I was wondering how best to respond to her in the meantime. At the moment we just reassure her that she is in her own flat.
