Mom Might Get Evicted from Memory Care

This may sound harsh, but it's our reality right now. We moved our 84-y.o. mother with dementia into a lovely memory care facility last week. The dementia symptoms advanced quickly - she was driving and socializing mid-February, and a month later she's getting lost in her own neighborhood, forgetting where she is, and falling often. 24-hour home care wasn't enough to keep her safe because of her constant falling. Mom is a classic narcissist who has played the victim her entire life. Basically, she's not happy unless she's miserable. She's rude and demanding. "Please" and "thank you" are not in her vocabulary. In addition to her dementia, she needs assistance with all ADLs. She's 85 pounds and a continues to be a severe fall risk. Because of the fast decline, we didn't know how the dementia would affect her personality, but it seems to have amplified the negativeness and rudeness. And she has become extremely combative. These traits did not truly show up until she was placed in the facility. It's not all the time, but when she has an episode, she hits, kicks, throws things, and screams ugly things at the caregivers. We know this because we have a camera in her room. We know she's being disruptive in this small community of residents and we're afraid they are biding their time before they ask her to leave. She's already been removed from having breakfast with the other residents. My sister and I stopped by yesterday to drop off some things and feel like we received an extremely cool reception from the staff, who up to this point have been warm and helpful. We also feel excluded from any discussions regarding her care, including ideas about managing her behavior. Question #1: how do we approach the staff about this? We feel like we're walking on eggshells around them. Question #2: What do we do if she is asked to leave? Are there facilities that can manage combative behavior? We're in Austin, TX
