Keys. If she has dementia, she’s like a little kid and you have to be the adult. She might not like you for it but her brain is also not functioning so you can’t take it personally.

Make sure she has power of attorney already set up. Take over her finances. If she still has capacity, get on her bank accounts so you can pay bills. But also realize depending how you do it, you may or may not own the money after she dies, so other siblings may get mad at you unless you play fair.

Move her into assisted living or with family if that’s what you want to do. There are placement agencies that can help but basically you can call around and find one you like.

The placement agencies usually have better connections for board and care facilities or unofficial places that may be cheap.

Hospitals have social workers that can help you with this. Ask her doctor to be referred to a social worker.

Assisted living is all private pay unless she has long term care insurance.

She may need to sell her home or rent it out.

You have to be the parent now. Treat her like you would a little kid. Please take control of the situation. Families always want others to make the decisions or do the dirty work but it’s so much easier if the family leads it. It helps when doctors or authority figures tell them officially they can’t drive but that should be ancillary to what you are doing.

If you’re not letting her live at home, just tell her the truth and then act.

Sorry you’re going through this.
