This study used animal models to investigate the effects of photobiomodulation (PBM) therapy on the brain’s glymphatic system and lymphatic drainage function.
PBM uses near‑infrared light to stimulate the brain’s lymphatic drainage system, which promotes the clearance of amyloid‑beta (Aβ) and helps remove metabolic waste products and toxins from the brain.
PBM treatment increased Aβ clearance in the brain and improved cerebral oxygen saturation and mitochondrial ATP production, exerting beneficial effects on brain health and highlighting PBM as a promising strategy for the treatment of brain disorders.
