Its good to see them classifying this as for "late onset Alzheimer's".
There is a theory that Alzheimer's as we currently understand it, is not one disease, but multiple diseases that are lumped into one category because we don't have an adequate test.
This is also where some of the controversy surrounding the Amyloid hypothesis comes from.
The more we learn, the more it feels like "Alzheimer's" is just a convenient label for a bunch of different underlying pathologies that happen to look similar on the surface.
The controversy over the amyloid hypothesis comes from a Stanford professor faking data[1] and setting the field back decades. The amount of harm this individual caused is hard to overstate. He is also still employed by Stanford.
