I have a dear sister-in-law who is suffering from Alzheimer. I want some advice on how to deal with certain situations. She keeps insisting that her grand father is in hospital recovering from some illness and she wants to go and see him. Her grand father has been dead for 60 years and she insists that no he is still alive. Would it be easier to agree with her and tell her that yes he is getting better and when he is back home we can go visit him?
