Definition

A concussion is a trauma-induced alteration in neurological function (Giza and Hovda 2014). Giza and Hovda (2014) and Hovda et al. (1999) expertly describe the abnormal neurometabolic processes associated with concussion. Early clinical signs of concussion include alteration of mental status or behavior and can be accompanied by other symptoms outlined below (see mild traumatic brain injury).

Diagnosis

Diagnosis of concussion is made based on identifying an event with adequate biomechanical force to cause a concussive injury and by examining acute injury severity indicators. Common mechanisms associated with concussion include a motor vehicle accident, fall, assault, or contact sports. In addition to a direct blow to the head, a concussion can result from rapid acceleration, deceleration, rotational or percussive forces that affect brain tissue. Injury severity indicators frequently used to diagnose concussion...
