Episode notes
Glymphatic System Clears Brain Waste
- The glymphatic system clears brain waste proteins like amyloid during slow-wave sleep, reducing dementia risk.
- Healthy blood vessels and astrocytes support this clearing, highlighting cardiovascular health importance.
Sleep Improvement Reduces Brain Amyloid
- Improving sleep quality in older decades correlates with lower amyloid and tau accumulation.
- Cognitive reserve and physical activity buffer against the negative effects of poor sleep on brain health.
Exercise and Cognitive Activity Buffer Risk
- Do 20-30 minutes of moderate daily exercise to offset dementia risk from poor sleep.
- Engage in cognitive activities to build cognitive reserve and protect brain function despite poor sleep.
