Here's a new twist on my situation that changes things, a little. I took my wife to her neurologist a few days ago for a checkup, and she performed the mini-mental and a few other verbal and paper and pencil tests. My wife scored better than she did the last time, and the neurologist now believes that she doesn't have dementia but has permanent memory loss from the ECT treatments she received in 2021. I feel alternatively sad because I authorized those treatments as her POA (nothing else worked to restore a degree of normalcy -- she experienced delusional thoughts, wouldn't eat, and wouldn't take her medicine), but relieved that while permanent, she probably won't experience further loss of memory. The neurologist said she could move out of Memory Care and into Assisted Living. The interesting thing is that my wife wants to stay in Memory Care. I think it's because she likes her roommate and is her unofficial private nurse's aide. Go figure!
