Hi: our medical facility offers a monthly dementia support group, and I bring my husband along. He likes to attend because they feed us lunch, however he does not interact. Hopefully you can bring your spouse along so you can get the benefit and she won't be alone.
I learned the word anosognosia on this site, meaning no self awareness. My husband is anosognostic, he doesn't realize he has any issues, which makes certain things harder since he's in disbelief or denial. Taking away his driving privileges due to safety concerns, and taking away his credit and debit cards due to misuse, caused major arguments. It was painful for me to have to do those things, and so confusing for my husband.
I'm not sure there is an easy way to make transitions.
Hope things go fairly well for you as you navigate the changes. Hugs, Judi
