Poor sleep may contribute to Alzheimer's disease
from CBS News
New research suggests that a good night's sleep may play an important role in helping protect the brain against memory decline associated with Alzheimer's. Researchers at the University of California-Berkeley found that a deficit in deep non-REM sleep, a sleep cycle associated with memory retention, was associated with a higher risk of buildup of brain proteins which are believed to play a role in triggering Alzheimer's disease. The buildup of toxic beta-amyloid proteins in the brain then leads to further sleep deprivation, resulting in a vicious cycle.
