Compared with other athletes, American football players do not seem to be at a higher risk of neurodegenerative disease, researchers say.

Traumatic brain injuries (TBI) are defined by the American Association of Neurological Surgeons (AANS) as "a blow or jolt to the head, or a penetrating head injury that disrupts the normal function of the brain."

All athletes are at risk of TBI, but the risk is especially high among cyclists and football players.
