Glymphatic Pathway

The brain's clearance system; activates during deep sleep to remove metabolic waste (e.g., beta-amyloid) via CSF circulation.

The Glymphatic Pathway is the brain's waste-clearance system. Cerebrospinal fluid (CSF) flows through periarterial spaces, exchanges with interstitial fluid, and flushes metabolic waste (including beta-amyloid) out of the brain, primarily during deep sleep.

Key Points

  • Sleep-dependent — ~90% of glymphatic clearance occurs during deep sleep
  • Temperature — core temperature drop promotes clearance
  • Posture — lateral sleep position may enhance flow
  • Insulin — caloric intake before sleep can impair clearance
