What kind of help can I get for a middle to late stage dementia Mom who lives in my home so that I can get a break a few hours a week?

ImTired, it sounds like you need to look around for respite relief. It would probably be easiest to hire a caregiver to come in on certain days and give you a break. Maybe you can hire one 1-3 days a week. Sometimes the states will have a little money to help pay for respite, but from what I've seen it is not much.

There is another option, but it might be confusing for your mother. Some nursing homes offer respite. You can have your mother stay a few days while you go on vacation. This is expensive, but your sanity is worth it.

In your position, I think I would opt for having someone come in. It would be very good use of your mother's money to give you time away each week.

Have you considered bringing in hospice? Sometimes they offer respite time as part of their services. I hope you are able to find someone so you can take breaks each week.
