The lady from the bank set my sister and I up to get the power of attny. Also helpd in getting my folks signatures verified (certified?) It was 20+ yrs ago and I forget the right term. My sister was an RN out on disability and I had taken early retirement for just this reason. I cooked and cleaned and learned to give injections. My sister took care of dealing with the doctors and hospitals since she spoke the language. Aside from that early $500 theft by the lawyer, we didn’t lose a dime. Just time and the heartache watching them deteriorate. Still, Dad made it to 85 and three months later Mom, who really wasn’t there anymore, made it to 82.
Like their doctor told us after Mom had passed, they wouldn’t have gotten a fraction of that care in ANY home...a fact I’m rather proud of.
Sounds to me that you and your sister did a good job with the hand you were dealt.
There are different groups of people who have to deal with Alzheimer's patients.
One group is parents getting Alzheimer's, then you have a wife or husband who gets Alzheimer's, then there are friends who become caretakers for a person who has no relatives to help them out, and probably another group that I am not familiar with.
To me you are going to need outside help that you will not get from the medical profession.
That is why I suggest getting a good elder services lawyer, who understands the laws in your state to help you out. - Tom
