Topic: Amyloid, tau and blood-test diagnosis

Alzheimer's disease is the most prevalent cause of dementia, which is defined by the combined presence of amyloid and tau, but researchers are gradually moving away from the simple assumption of linear causality proposed by the original amyloid hypothesis. Aging is the main risk factor for Alzheimer's disease that cannot be explained by amyloid hypothesis. To evaluate how aging and Alzheimer's disease are intrinsically interwoven with each other, we review and summarize evidence from molecular, cellular, and system level. In particular, we focus on study designs, treatments, or interventions in Alzheimer's disease that could also be insightful in aging and vice versa.

Key findings

Why it matters

This review discusses how aging and Alzheimer's disease are interwoven at molecular, cellular, and system levels, and notes that researchers are moving away from the simple idea that amyloid alone causes the disease. It is a summary of evidence and ideas, not a report of a treatment or cure.
