Mom has been in assisted living just for 2wks the facility has 55 residents. One lady is wheelchair bound with dementia and makes the habit of going in the other resident's rooms. I feel for her but she has come into my mom's quite a bit for only 2wks (doesn't say anything if you tell her "no Mary" she will leave. Mom called me historical and crying and say she hated it there and this woman is going to drive her nuts. I know she has rights but they are good to her
I know this is incredibly stressful for you, but it's only two weeks - give it more time. You might find it helpful for your own peace of mind (and for heaven's sake don't tell your mother this!) to set yourself a notional deadline - say, three months - and resolve that if she's still climbing the walls at this facility you'll consider others. Are there alternative, possibly better options?
What is the facility's policy on those that need more care than they can provide? What is state law on facilities providing care to those with dementia? Do they have the appropriate resident/patient ratio since they are caring for dementia? What does mom's lease say about this sort of issue?
She might in fact just be lonely, so if staff can find a way to rechannel her visits, that might be helpful.
In regular AL I think that they sometimes have dementia patients that may be too advanced for them to properly supervise. They may need to review this lady's behavior to see if that is the case. Most the AL and MC facilities that I have seen, the residents love to have visitors come to their rooms.
My Dad had a situation where he was in his bathroom and when he came out there was this lady he didn't know fast asleep on the top of his bed. Oh dear, Dad [95] called me in a panic as he didn't want to get into any trouble. I had him push his medical alert pendent and the Staff came in and redirected this lady to her room.
When I asked the Staff the next day about this, turned out it was true, the lady tends to wander. As long as Dad knew he wasn't going to get into trouble, he was ok about it if it should happen again.
When my Dad was in Independent Living, he liked keeping his door opened, as people would walk up and down the hall, and call into him "Hi Bob" if they saw him in his recliner. He also did the same thing in Memory Care, it made him feel like his room was larger if he could see the common living room in his corner of the building.
