My mother has had vascular dementia for over 3 years now and has a number of care packages in place that are enabling her to stay at home. Recently she has been saying that overnight, people are coming into the house, they have a key, and sleeping in the other bedrooms, then making a mess. This is distressing her and I find it difficult to know how to support this behaviour. I don't want to argue with her and say it's her illness but she keeps talking about it even when we are discussing other things.
