A concussion is a type of traumatic brain injury that is caused by a blow to the head or body, a fall, or another injury that jars or shakes the brain inside the skull. Although there may be cuts or bruises on the head or face, there may be no other visible signs of a brain injury. Concussions may happen in any sporting activity and can occur in many different ways, for example: a player hitting their head on the ground, or being struck in the head by an object or another player. A concussion can be accompanied by loss of consciousness; however this is not common in most cases. A startling 1.6 to 3.8 million concussions occur each year, 80% of which go undiagnosed.
