Abstract: Photobiomodulation or low level light therapy is applied to the brain using a treatment protocol that shows improvement in treating a number of disease states and injuries of the brain. A laser probe including an LED cluster is placed perpendicular to the skull at a plurality of identified treatment points on the patient's skull for durations of 1 minute with pulsed waveforms at each location. The pattern for the treatment points varies by disease or injury state being treated. The treatment period is typically on nonconsecutive days for 6 weeks (3 times per week) or 9 weeks (2 times per week) per treatment protocol. Patients with Parkinson's disease, Alzheimer's disease, balance issues, concussions, depression, strokes, and other brain diseases or injuries have shown dramatic improvement under such treatment protocols.
