What is the difference between dementia and Alzheimer?

Carefully look at the amount of care and attention he gets in the nursing home and Carefully look at the amount of care and attention he gets in a assisted living setting; then you may be better off spending down and replicating this in your own home.

Will you find it necessary to hire your own caregivers to supplement their care levels?

I agree with Windyridge above about your hubby needing a lot of care. Sadly with Alzheimer's/Dementia the medical issues just keep getting worse and worse. There is no way to rehab the mind. And at your age [you are just a couple years older than I] I know I wouldn't have the physical energy nor the mental energy to deal with someone who has memory issues.

Now, if you have enough funds you can have paid caregivers from an agency come to the house to help you. You can try the daytime shift and see how that works out, and see if you are able to deal with the night-time issues. If not, then you would need around the clock caregivers. And depending on where you live, it can go up to $20,000 a month, yes a month. If you bring someone in from outside of a licensed, bonded and insured agency, then you would need to purchase a workman's comp rider on your homeowner's insurance and those can run up to $1k a year.

It would be possible to care for him at home but given your age, your health and his condition this would be very difficult. His dementia is going to get worse and the level of care will increase. If you have the funds for lots of in home help it may work but how is he doing in the nursing home? Look at the amount of care and attention he gets in the nursing home and think about replicating this in your own home. Are you up to this?
