My father is 86 and though not yet diagnosed, he is suffering from some type of dementia. He has always been pretty mean with a trigger temper. We'd like to keep him in his house until the very end. We've hired a home care professional that comes in every day for four hours. He's terribly mean to her and threatens to kick her out -- and does kick her out -- often. When I try to explain that we are helping him, he says he's not a two year old -when actually he is. He wears diapers and poops in them and doesn't want to change them or bathe. He won't eat except for chips and sweets. He's even pooped on the floor and denied it. He's in a state of constant combat. Everything is a fight! Everything! Even when I get him calmed down and try to make sense of everything, he stops, gets angry and hangs up on me, or if I'm there, he starts cussing and shuts down the conversation and leaves the room. He wants to move in (sometimes) with my sister who lives about 15 mins away. He's stayed there after surgeries and a stroke in 2010, and just refuses to accept that it is HER house, disrespects her children and their privacy, etc. He believes family should be taking care of him, but I live 2.5 hours away and come down once a month to cook and stock his freezer with food. My sisters go over every day and it normally turns into a fight. One of them does provoke him, but it normally comes after he's strongly resisted following some rule, like bathing, changing his clothes and mainly his diaper, throwing out spoiled food and making sure he doesn't eat it. We've threatened him with a nursing home, which he doesn't want. He believes his family should take care of him, but can't see that we are! Help!!
