Medical facilities for the "physically incapable" and medical facilities for "memory care" are VASTLY different.
You don't get admitted to a "memory care" facility easily (multiple doctors and psychiatrists have to sign off) and it's expensive once you do (health care only really pays during immediate medical events).
I do know that there are horrors in nursing homes. I also know from personal experience that there are also good ones. But, it, as always, comes down to money.
In my experience it's relatively easy to get admitted to a "memory care" facility even if someone shouldn't be there. All it takes is a dementia diagnosis and a bunch of doctors who don't care enough to look harder.
I have no clue where you're located, but that simply is totally alien to my experience.
My mother had to have 3 independent assessments before they would authorize permanent admission. And her Alzheimer's was beyond obvious once you knew what to look for.
A friend of mine wound up in a hospital mental health care facility in California, and within 48 hours had a state appointed patient advocate who immediately started forcing the doctors to justify their assessments. The doctors played some games, but at the end of 10 days, he was released as he should have been since whatever the "episode" was had clearly passed.
We're in California as well. The state is pretty good with involuntary holds where someone is being deprived of their rights, but anything that's voluntary doesn't fall under that, even if the patient and/or their family made that decision based on tall tales a physician or physicians spun.
