This is a test for people who already have symptomatic dementia that helps confirm the diagnosis.
Well this test isn't for whether you will get Alzheimer's, so that disqualifies it before we even consider the accuracy.
But apparently your odds go above 30% if you live long enough, so if you could test for being in that cohort I think that result would be too common to actually be devastating.
