Matt explores the critical link between sleep and Alzheimer's disease today, explaining how the brain’s "glymphatic system" clears toxic proteins like amyloid and tau during deep sleep. He describes how insufficient sleep impairs this process, creating a vicious cycle where protein accumulation damages sleep-generating brain regions and increases dementia risk.

Matt goes on to discuss groundbreaking research on a new class of sleeping pills, Dual Orexin Receptor Antagonists (DORAs), that may enhance this cleaning mechanism. While preliminary human and animal studies show these drugs can reduce toxic proteins and offer neuroprotection, the findings underscore the profound importance of prioritizing high-quality sleep as a powerful, accessible tool for ensuring long-term brain health.
