My Medicare Advantage plan sends an NP around to my home every year to check my general health. This year for first time (I am 81) it included a test of remembering three words while drawing a clock that said 2:15. I passed this okay, but I do carry one ApoE4 gene for late onset Alzheimer's--although neither of my parents lived long enough (62 and 80) for dementia to be obvious. Nor did my grandparents who all died in their early 80s of heart attacks or colon cancer. I am also taking some online tests each year through Brain Health Registry that I find extremely difficult but they don't tell me how I am doing. Is this clock thing really important, and how do you know if you are developing AD versus normal cognitive decline with age?
