What is a Concussion?

A concussion is a neurologic injury that causes a temporary disturbance in brain cells, as a result of extreme acceleration or deceleration of the brain within the skull. The common misconception is that you must be hit in the head to cause a concussion injury – this is not true! Because a concussion is the result of acceleration or deceleration of the brain, a concussion can happen with a significant blow to anywhere on the body.
