Concussions and traumatic brain injuries are an increasing source of controversy in professional sports leagues. Football players are celebrated for their big hits and brutal tackles, but that glory comes with a devastating cost.
When a football player receives a blow to the head, it can cause the brain to bounce or twist in the skull. This sudden movement causes stretching, cell damage, and chemical changes in the brain, making it more vulnerable to injury and stress until it recovers.
