ISO tips for aging parent with no STM waffling a major decision
My 83 yo father has zero short-term memory and is dx with cognitive decline not altizmers-related. My 80 yo high-functioning mom, my brother and I are coaching him through a major and emotional financial decision.
The waffling back-and-forth is reaaaly frustrating. One hour he'll passionately align with the "right" decision (objectively right in all regards, but emotionally painful). An hour later he's just as passionately exactly opposite.
We wind up carefully repeating the very same long, protracted, detailed explanation over and over, eventually convincing him, again, to do what's right. Hours or days later we're dealing with the very same outbursts when he switches back. He's not exactly "changing his mind" - he seems to have no recollection of the last ten times we did the same dance.
Now it's getting serious, because people from outside the family are getting involved. We need their help to do what's right, but I'm worried they're going to eventually say, "Fuck this!" and walk away - which I'd completely understand.
Any tips for helping HIM remember what he decided, why, and what's next? How can we help him maintain the mindset to do what's right long enough to actually do it?
Thanks for taking a look.
