Nature Medicine that shows how the tau protein spreads in AD according to four distinct patterns that lead to different symptoms with different prognoses of the affected individuals.
“Alzheimer’s disease (AD) is characterized by the spread of tau pathology throughout the cerebral cortex. This spreading pattern was thought to be fairly consistent across individuals, although recent work has demonstrated substantial variability in the population with AD. Using tau-positron emission tomography scans from 1,612 individuals, we identified 4 distinct spatiotemporal trajectories of tau pathology, ranging in prevalence from 18 to 33%,” write the investigators. ....

Study shows how tau spreads to four distinct patterns leading to different Alzheimer's symptoms


Study shows how tau spreads to four distinct patterns leading to different Alzheimer s symptoms
Alzheimer s disease is characterized by the abnormal accumulation and spread of the tau protein in the brain. An international study can now show how tau spreads according to four distinct patterns that lead to different symptoms with different prognoses of the affected individuals. The study was published in
Nature Medicine.
In contrast to how we have so far interpreted the spread of tau in the brain, these findings indicate that tau pathology in the brain varies according to at least four distinct patterns. This would suggest that Alzheimer s is an even more heterogeneous disease than previously thought. We now have reason to reevaluate the concept of typical Alzheimer s, and in the long run also the methods we use to assess the progression of the disease. ....
