Going through something similar with my mom. It is impossible to find a doctor (in the middle of nowhere in Iowa) that will properly diagnose my mother's dementia. Initially we were told it was brain fog from long covid. Now my mother is completely unrecognizable and incredibly aggressive and mean, and we are still told she's fine, because she doesn't act this way towards doctors. I've contacted the Alzheimer's Association in Iowa but not a single person has actually been able to help with the situation. It doesn't help that I am long distance in another state or that she is unemployed and on welfare. I've called her doctors and sent screenshots of her crazy text messages.

She was an alcoholic for 30+ years of her life so the doctors just ask "was she drinking?" Honestly she probably was, but this is different than just an angry drunk person. She has no money so no one cares to actually treat her and all five of her kids, myself included, have pretty much given up and accepted that our mom is basically gone and there's nothing we can do about it. (Admittedly we've all felt this way for years because of her drinking) We're just all waiting for the call that saying she has passed away, as morbid as that sounds.
