What Is a Concussion?
A concussion is a brain injury that changes the way the brain normally works. Concussions are caused by a blow to the head or by forces transmitted to the head following a blow to the face, neck or body. Sometimes, even what seems to be a mild blow to the head, face, neck or body can lead to a brain injury.
You can’t see a concussion. Signs and symptoms of concussion can show up right after the injury or may not become apparent or be noticed until days or weeks after the injury. If your athlete reports any symptoms of a concussion, or if you notice these symptoms, seek medical attention right away.
