Episode notes
Dementia Starts With Nighttime Habits
- Dementia begins decades earlier due to poor sleep, blood sugar swings, and inflammation.
- Nightly habits before bed determine whether your brain detoxifies or accumulates toxins.
Glymphatic Drainage Needs Low Insulin
- The glymphatic system clears amyloid and tau during deep delta sleep when insulin and glucose are low.
- Eating close to bedtime keeps insulin high and blocks this nightly brain 'wash'.
Late-Night Glucose Fuels Brain Stress
- Overnight high blood sugar shifts mitochondria to burn glucose, producing reactive oxygen species and microglial activation.
- Elevated insulin correlates with lower melatonin, increasing neuronal oxidative stress and sleep disruption.
