Midlife Blood Clues Could Flag Alzheimer's Risk Before Symptoms
TL;DR Summary
Dunedin Study findings suggest that higher blood levels of pTau181, together with self-reported memory concerns, may reveal Alzheimer's risk as early as age 45, highlighting midlife as a key window for brain health; pTau181 did not correlate with MRI or cognitive tests at 45, and researchers will continue following participants to see how this risk marker evolves.
