Study restores sleep in Alzheimer's without clearing brain plaques

Original: Alzheimer's breakthrough: 2 hrs of sleep restored without clearing brain plaques

Researchers report an Alzheimer's-related breakthrough in which around two hours of lost sleep were restored in patients or models without reducing amyloid plaques in the brain. The finding challenges the assumption that plaques must be cleared to improve symptoms, suggesting sleep disruption may be treated through other mechanisms. The result is drawing wide attention in science and health communities.

Why now: It challenges the dominant plaque-focused theory of Alzheimer's treatment, which has major implications for drug development.
