The Alzheimer's Turning Point: What We've Learned and Where We Go From Here The long sought "tipping point" in Alzheimer's disease has finally been identified.
For decades, scientists have searched for a single trigger or biomarker that would explain why some people with the hallmarks of Alzheimer's remain cognitively healthy while others succumb to dementia.
The latest research suggests this turning point lies in the brain's immune cells – specifically, microglia – and how they respond to amyloid plaques and tau tangles.
