Mom is at this location in memory care. They are taking good care of her. I feel that if she starts doing more things for herself in the memory care unit, which was supposed to be temporary, that she can pretty much fend for herself. Except for a couple minor details. She is 88. She has been there for 3 months.

Have you done much reading about dementia, which your profile says that your mother has been diagnosed with?
Dementia does not "get better". It gets worse. It is a progressive, fatal disease.
Go to Alz.org and do some reading and you will get a better idea of what to expect.
I agree, by the time MC is needed, the person is pretty well into their Dementia. I doubt if the person would ever be able to do for themselves. Temporary may mean to get her over a hump but she probably still need 24/7 care. Are you prepared for that?
