my dad has lewy body dementia which is progressing quickly. he is worse at night, unable to sleep, wandering, looking for people or items and getting very angry. he tells us to leave as he doesn't believe we live there and gets very distressed.this can go on for hours. In the morning, he knows somethings happened and he's the cause. The worst thing is, he tells me he's terrified!! I don't know what to do?
