This is a recent change in her behaviour and seems to be becoming more frequent. Staff in the care home tell us she is refusing to get out of bed, resists their attempts to help her with food, drink or personal care, and is becoming increasingly aggressive. Is this normal in dementia? Can anyone help us with advice as this is so out of character for the person we know and love - and we really don't know how best to respond at such times. Do we just leave her to spparently sleep on, attempt intervention - and if so, how?

Just might thought, it could be that your Mum-in-law thinks by closing her eyes that you won't see her.
