My 97 year old father with dementia has a 24 hour carer and 4 weeks ago he became unwell, took himself to bed, stopped eating and has been sleeping all day and night and has barely got up. He can barely walk now, the doctor has been a few times and naturally we have been so worried about him and then tonight he decided to get up and eat pancakes and custard for supper! Is this normal. It is like a roller coaster.
