Deep sleep plays a critical role in Alzheimer’s, scientists confirm

From Futura

A new study has found that deep sleep may protect memory even in people showing early signs of Alzheimer’s disease. Researchers observed that individuals who enjoyed consistent, high-quality sleep retained their cognitive abilities better — despite having the same levels of amyloid proteins linked to Alzheimer’s. The discovery offers real hope in the fight against a condition that affects millions worldwide.

Alzheimer’s remains one of the most devastating forms of dementia. But scientists now believe that a simple, everyday behavior — deep, restorative sleep — may serve as a natural shield against cognitive decline. According to a team from UC Berkeley, Stanford, and UC Irvine, this particular sleep phase could help preserve memory even when the brain has already begun to show signs of the disease.
