Brain

Waste Removal System and Sleep

Conclusion
  • This study highlights the effects of photobiomodulation (PBM) on the brain waste removal system (BWRS) during deep sleep as an innovative strategy for nighttime treatment of brain diseases.
  • In the study, photobiomodulation at a wavelength of 1267 nm was used to activate the BWRS during sleep, which was found to promote the clearance of brain metabolites and toxins and to modulate the function of cerebral lymphatic vessels.
  • PBM treatment was observed in animal models to facilitate the removal of beta-amyloid and improve neurological status, suggesting the potential benefits of PBM in the treatment of brain diseases (p < 0.05).
