New to this and in need of guidance

Welcome. Sorry you need to be here. One of the most important things you should do is see a lawyer about a DPOA, medical poa, will, and living will. Do not wait if this has not been done. It’s very important. As far a a walker I think Medicare will cover it if there is a doctor prescription. It’s usually not long after diagnosis that she will not be safe to live alone. 24/7 in-home care is very expensive and usually not covered by Medicaid or Medicare. You might be able to get her a bit of help by contacting your local commission on aging. They can at least tell you what services are available and who to contact. If a facility is in the the future plan you should keep in mind that there can be a waiting list. Qualifications and what is covered by Medicaid varies by state and it can be complicated. This is something you might want to talk about with a lawyer. I would recommend you keep a very close eye on her. It’s easy to assume that our loved ones are capable of things only to find out later they are not. For example, I took mom to the dentist every 6 months and she got a new toothbrush. When I moved her I found a bunch of new toothbrushes. She had not swapped out her toothbrush in a very long time. She appeared to be doing her own laundry, but then I noticed she had run the washer without putting clothes in it. Im sure she occasionally actually remembered to put the clothes in, but she was clearly not as capable as I thought. Finances are one of the first things a pwd is likely to have problems with. Keep a close eye on things (or just take things over, with the DPOA). She is very vulnerable to scams and bad decisions. I will attach a few resources that might be helpful.
