Any ideas of what I can do if he continues to refuse someone in the house to help? I can't live there and can't fit them in my home. I work part time, have a teenage son and husband. Try to go there as much as I can but he leaves her alone which isn't safe, and when home usually just leaves her in front of the TV all day which is not good for her brain. I don't know what to do, he is so stubborn and after 70 years together insists he doesn't need help taking care of his wife.
But. There is still a lot he must learn about Alzheimer's Disease if he is to remain in charge as his wife's primary caregiver, as well as her devoted husband.
How does he get on with their family doctor? You need someone he trusts, who has some authority with him, to get the message through to him that your mother's safety needs extra care now. He doesn't have to be a prisoner in his own home, but he does have to make sure that if he isn't there to keep her safe then somebody else is.
Baby steps, one at a time. As long as your mother is happy to watch t.v., leave "stimulating activities and socialisation" for later, once your father has accepted that a person with dementia does need extra support (as does an elderly gentleman who is handling all this responsibility so bravely).
