Traumatic Brain Injury

Traumatic brain injury (TBI) is a brain dysfunction caused by some type of trauma to the head, often resulting from sports injuries, road traffic accidents,  or blast injuries suffered in military conflict. 

TBI can be expressed in a wide range of symptoms, including initial loss of consciousness, recurrent headache, cognition impairment, sleep disturbance, mood dysregulation, anxiety, and irritability

TBI is classified as mild, moderate, or severe, depending on the severity and duration of symptoms post-trauma. Repeated episodes of TBI can develop into chronic traumatic encephalopathy, which is recently becoming a recognized condition found in boxers, football players, and military personnel. 

There is presently no standard treatment for TBI, but some novel approaches are being investigated and tested in both acute and chronic settings. One of these novel approaches is photobiomodulation (PBM) utilizing near-infrared light stimulation. 

Clinical studies utilizing PBM for individuals with traumatic brain injury have shown promising results, in terms of improvements in cognition, verbal memory, PTSD, and sleep.
