Hi. My brother was diagnosed with Alzheimer's about eighteen months ago. He lives alone but has a close friend and neighbour who cares for him. The other day she arrived in the morning to find that he had trashed his sitting room. Furniture was overturned, pictures off the walls and belongings scattered around. She woke him up and asked him what had happened but he had no recollection at all. This is not something that has happened before. Does anyone have any similar experiences?
