Mild traumatic brain injury (mTBI), also known as concussion, occurs commonly in sport and Motor Vehicle accidents. The Centers for Disease Control and Prevention estimate that as many as 3.8 million sport-related concussions occur annually in the United States. Despite ongoing research, there is no highly sensitive clinical test for cognitive function that can be rapidly applied in a sporting environment. This makes the clinical diagnosis of concussion particularly difficult, as the clinical presentation of concussion is highly variable with symptoms often evolving over time. Furthermore, with less than 10% of concussions resulting in loss of consciousness, self-reported symptom presence may be the only initial evidence of a concussion. These factors make concussion a challenging injury to diagnose. Given the variability in concussion presentations, there is no single test that can diagnose a concussion.
