Mom has had 3 strokes (brain bleeds) and has Parkinson's. She falls a lot, probably 3 or 4 times just this past 2 weeks. Not safe for her to cook due to memory issues. I think she should be in assisted care. Dad does "not want to live with old people" - he's 84 for gods sake - and refuses to get help in for Mom. Keeps saying he can take care of her, but this is not realistic, and he says she refuses to allow him to get her the help she needs. Now he wants to just take her to assisted care facility and leave her there. I think he has a good degree of dementia as well - so while he asks for thoughts and guidance, he does not accept thoughts that are not his own. I think it is a matter of time before she is really injured. How do I convince them to accept the assistance options that are available for people to stay living in their own home, or to go to assisted care?
What dad wants is not what's safe or good for dad. Or mom.
If their need level is similar, you may be able to find a double they can both live in together. Or at least on the same campus. A lot of married couples are moving into "independent living" apartments, and transitioning into other units as their care levels increase. You can bring furniture from home.
A difference is they won't be isolated at home, watching TV all day. There are activities, outings, and a lot of services come on site vs them having to go out. My mom's place had visiting doctors who saw her in her apartment. They could do everything but imaging. Onsite PT, dentist, post office, gift shop, barber/beauty, dining room.
As mom's dementia advanced, she simply transitioned into other units on the same campus.
My advice is to put them in a place that can handle the next stage of need, not what they need today. Things change so quickly you don't want to be looking for another place for them in 3-6 months.
Some level of guile is required to do this. You can't just blast them with "you're not safe anymore and you have to move." You many need the doctor to tell dad it's time for change, for mom's sake. Most elders will listen to an authority figure who can appeal to their ego. Unless reasoning is farther gone than that. If so, you may just need to do what you have to do. They won't stay mad at you forever.
