That’s a very tough situation MartinFocazio.

There are three options that come to mind. You could, if you or they could afford it, get some kind of support for them at their home. My grandmother, before she passed, was able to get along for years with the help of a young man who could maintain the property and drive her places. Second is to have someone live with them, either at their place, yours or some other place. And third is to find them some kind of assisted living arrangement.

You may have to go to court and have them declared incompetent if they refuse all workable options..
