It’s also not clear that one can measure progression well enough that an n=1 data point is meaningful. And I’m also far from convinced that very early Alzheimer’s that would progress rapidly enough to be noticeable can be detected with enough specificity to rule out fairly common cases of people who test positive but effectively don’t have the disease.
