My mother lives in a major city about 6 hours drive away, where my brother takes on the main burden of caring for her. She is in her nineties, and has dementia. That is, I will repeatedly say the same things in the same conversation, each time as if it was the first time.
Her main social outlet outside the home is mahjong (though my brother and his wife visit and shop for her regularly). Due to her declining cognition, she can only go when her Mahjong partners come to pick her up. I guess it is about once a week, on average. However, her losses are about $1,000/month, give or take 50%. We know that funds will be needed when we can no longer provide the care needed to live outside of an institution, so this loss is worrisome. My brother has visibility into the bank withdrawals, but my mother doesn't remember making them, and is unable to keep track of them. If we are too resistant to bringing her to the bank, she will just go on her own, which is very hazardous.
What strategies are there to address the uncontrolled loss? There is value in Mahjong's socialization, but we suspect that she is being exploited for her dementia. Neither she nor we have control of the situation.
