A concussion occurs when a force causes the brain to move rapidly inside the skull, which can result from a direct blow to the head, face, neck, or elsewhere on the body with an “impulsive” force transmitted to the head. This sudden movement can cause chemical changes in the brain and damage to brain cells. Concussions can happen in many settings, including sports, car accidents, falls, or during recreational activities. It’s not always associated with loss of consciousness but always requires evaluation for appropriate care.
