Photobiomodulation (PBM), using red light (600–700 nm), near-infrared (700–1100 nm), and LED devices, is transforming brain health. This non-invasive therapy shows promise in preventing neurodegenerative diseases like dementia and Parkinson’s, managing early-stage symptoms, and aiding traumatic brain injury (TBI) recovery in athletes. By stimulating cellular repair, reducing inflammation, and boosting brain resilience, PBM offers hope for diverse neurological challenges. This
