The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.
And now we offer this for-- think there was no test for Alzheimer's, right? You had to do a brain biopsy, or you had to wait until you forget your name of this or that or the other thing. And now we can, through blood testing, look for things like P tau 217 and amyloid 42-40 ratios.
Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

Research suggests that p-TAU217 could serve as an initial screening tool for healthy individuals. Those with elevated blood p-Tau217 levels should then undergo brain imaging.
A recent study found a simple p-Tau217 blood test to be as predictive of future cognitive decline risk as more complex brain imaging of Tau tangles.
A study found a simple p-Tau217 blood test to be equally predictive of future cognitive decline risk to much more complex brain imaging of Tau-tangles.
When this protein builds up, it's a sign your brain could be in trouble later.
Plasma levels of p-tau217 were able to distinguish between people with a high likelihood of Alzheimer's and those without it with 98% accuracy.
A new blood test may detect Alzheimer's disease up to 10 years before clinical diagnosis with 100% accuracy.
