What is a concussion?
A concussion is defined as a trauma induced alteration in mental status that may or may not involve loss of consciousness. Concussions occur from forces applied directly or indirectly to the skull that result in the rapid acceleration and deceleration of the brain. The sudden change in cerebral velocity elicits neuronal shearing, which produces changes in ionic balance1 and metabolism.2 When accompanied by clinical signs and symptoms, changes at the cellular level are commonly referred to as mild traumatic brain injury, or concussion (NATA Concussion Position Statement, 2014).
