Hello. My OH has vasculair Dementia and was diagnoses about 4 years ago. Recently his behaviour has changed considerably. He no longer goes out of the house and rarely makes it downstairs. He sits in his chair or in bed all day and shows little interest in life. He eats and drinks but only very little, and is losing weight. More worryingly, he gets extremely agitated at night, hallucinating about things I cannot understand, which makes him very angry. He has also recently started to get very confused about toiletting, which often culminates in a flood, or worse, in the bedroom or bathroom. He's not incontinent, just confused, although nothing has changed and he has a commode next to the bed. I do my best but with little sleep and difficulty in leaving him alone I am beginning to lose heart. Help!
