My father thinks he can take care of my mom with severe dementia, but he is not doing a good job. She doesn't eat healthy or eat much at all. She has lost 25 pounds since last summer. She sleeps a lot and he leaves her alone at times for a few hours, saying the neighbors check in on her. My brother, sister and I can not convince him to get professional full-time help or any help at all. We are at our wits' end. Anyone else have this issue?
