My father is 95 and has advanced stage dementia. Sometimes he sleeps for two days, other times he is up all night rearranging things. A new development is that he takes off all his clothes in bed and removes the sheets from the bed. He fights me when I try to get him cleaned up. Not even the caregivers can touch him sometimes. I am at my wits end. We have a new caregiver coming tomorrow. I hope that she will be able to handle him.
