Assisted Living - Could be a Sunrise type facility, nice apartment style units, 24 hour nurse station.
Nursing Home - Single room, communal areas, round the clock care
Hospice - Single room, residents are dying, round the clock care
I'm guessing there are some variations for assisted living and nursing home. For the former, could even be a housing development with round the clock care, that would be something like the The Villages I'm thinking?
My mom's oldest sister is 88 and lives with one of her daughters, that's the Japanese way.
My local buddy who's Polish, his mom who is not all that old has dementia, they have a day time nurse and he watches her on weeknights and they have some sort of arrangement for the weekends, mix of nurses and his siblings.
When my wife's grandmother was diagnosed with lung cancer, there was a general sense she had a year or two left. She was up there in age, I'm guessing upper 80s. So my inlaws drove down to FL and helped her sell / give away items, sell her house which I think was in something like The Villages. She lived with my inlaws for nearly a year, but then it was too difficult for my inlaws to help her bath and go about her day. She went to hospice and was gone in about 4 months.
It's my hope that my mother becomes willing to live with my youngest sister in the next two years, my mom is 83. I think it will actually increase her confidence in driving and getting around which is has been decreasing lately.
