When to make the move to AL or MC?

My mother is 82 and in the mid stage of Alzheimers disease, losing everything, can't find anything, squirreling away anything of value because she thinks that someone is stealing from her, only eating one meal a day (because she is not hungry and doesn't want to gain weight), getting confused with paying bills, missing payments and misplacing bills altogether, not remembering what day it is, what month, or season. I have noticed that she has not been doing her laundry very frequently, and has not used her shower in a while, instead she is washing herself at the sink. She is currently in independent living community and she still plays cards (pinochle) with friends twice a week. She is trying and trying to put puzzles together with a male friend of hers, and she enjoys his friendship.

I have been calling her twice a day for the last 2 years (AM &PM) to remind her to take her medications, and to check in on her, as I live out of state. But I cannot guarantee that when she hangs up with me, if distracted by something, that she will take her pills or eyedrops.

At this point in time, she is able to use the bathroom and she is not incontinent. She spent a week with me over Christmas, and was not incontinent, but she didn't remember my husband, being at my wedding, or ever being at my house before. She thought that she was at a beach house that we rented, and at sundown every evening the repetitive questions began. When she returned to her IL community, she was very confused and was looking for me at the concierge desk for a few days after I left.

I am worried about moving her to AL or MC because of the friendships she has at her IL community but my gut is saying that she needs to be somewhere where she can be watched.

(She has told my sister and I that she will walk out if we move her to the AL or MC.)

How did you decide to help your PWD make the move to AL or MC?

Thanks,
