In a post a few days after the one I've linked to here, I did mention that a little detective work yielded the information that she does get Meals on Wheels. I also know, over a year later, that she doesn't let them in the house -- but at least I know she's getting nourishing food.

I'm a layperson, I know, but I do wonder if there's not some pathology at work here. She's showing signs of being a classic late-stage compulsive hoarder; and if she is one, not only is a simple cleaning regimen not going to work on her (not even if someone else is doing the cleaning), but trying to get someone in there to get started would be perceived on her part as a threat, and could do her serious damage.

Still, though, it's worth a call to the council on aging to find out if there are advocacy groups who can deal with her compulsion while allowing her to keep her dignity and autonomy. I have the number, and I'm planning to call this afternoon.
