Levels of beta-amyloid, which accumulate in the brains of Alzheimer's disease patients, decreases during sleep. Scientists have discovered a new pathway that clears toxins from the brain known as the glymphatic system that is managed by the brain’s glial cells.
The glymphatic system clears the beta-amyloid in the brain while we sleep. Sleep may allow the brain to ‘take out the trash’ that causes other neurological issues.
This may also explain why sleep improves memory storage. Another reason to get more sleep!
