Concussions are traumatic brain injuries that result from “brain shaking” that can occur during any situation that may transmit force to the head. Concussions are defined as a clinical syndrome characterized by immediate and transient post-traumatic impairment of neural functions which lead to a complex grouping of both psychological and physiological symptoms. As knowledge of the long-term implications of these injuries grows, concussions are becoming more of a major health concern worldwide. One subset of concussion classifications, sports-related concussions, is receiving an increasing amount of attention from scientists and health-care practitioners alike. It is estimated that more than 3.8 million sport-related concussions occur annually in the United States alone, and some studies suggest that up to 43% of these go unreported and untreated.
