claimDuring sleep, the human brain clears out beta-amyloid and other toxins, whereas insufficient sleep allows these Alzheimer’s-related proteins to accumulate at a faster rate.
claimThe glymphatic system flushes out plaque-forming proteins, specifically beta-amyloid and tau, which are associated with Alzheimer’s disease.
claimThe accumulation of waste products like beta-amyloid and tau in the brain over years and decades is thought to contribute to memory loss and cognitive decline associated with dementia.
