The findings were reported online yesterday in the journal Public Library of Science Genetics.

It has recently been established in multiple studies that elevated levels of this protein in cerebrospinal fluid indicate Alzheimer's, and that because symptoms can reveal themselves slowly, testing levels of tau would offer a glimpse into the future--a red pill, if you … Read more
