Photobiomodulation of Brain Waste Removal System

The meningeal lymphatic vessels (MLVs) are an important part of the brain waste removal system (BWRS). A decrease in MLV function is associated with various brain diseases, including Alzheimer's and Parkinson's diseases, brain tumors and trauma. Augmentation of the BWRS might be an innovative and promising strategy for neurorehabilitation medicine. Here we discuss that photobiomodulation of the BWRS/MLVs during deep sleep is a breakthrough technology for the effective removal of metabolites and wastes from the brain in order to increase the neuroprotection of the brain as well as to prevent or delay neurodegenerative diseases.
