Photobiomodulation is traditionally associated with treatment of various skin conditions, including wound healing. However, in recent years there has been a growing interest in applying this method for treatment of brain disorders. Traumatic brain injury is a common type of head trauma, affecting victims of sports injuries, assaults, injuries suffered in military conflict and road traffic accidents. There is a lack of therapeutic methods for traumatic brain injury, especially those that can be applied non-invasively.
In this webinar hosted by the OSA Therapeutic Laser Applications Technical Group, Michael Hamblin will discuss principles of photobiomodulation (PBM) for treatment of traumatic brain injury. PBM employs red or near-infrared (NIR) light (600-1100nm) from lasers or, in some cases, light emitting diodes to stimulate healing, protect tissue from dying, increase mitochondrial function, improve blood flow, and tissue oxygenation. Results of small animal model studies as well as human studies show that PBM can also act to reduce swelling, increase antioxidants, decrease inflammation, protect against apoptosis, and modulate microglial activation state.
All these mechanisms of action strongly suggest that PBM delivered to the head should be beneficial in cases of both acute and chronic traumatic brain injury. Moreover, PBM has now been shown to be effective against neurodegenerative diseases (Alzheimer's and Parkinson's) and psychiatric disorders (depression, anxiety and opioid addiction). Cognitive enhancement in normal individuals is another application.

• Therapeutic effects of NIR light treatment on brain tissues
• Principles and mechanisms of PBM for treatment of traumatic brain injury
• Applications of PBM to treatment of neurodegenerative diseases and psychiatric disorders
Who Should Attend:
• Students, scientists, physicians interested in applications of non-invasive light therapies for healing of brain tissues
