A concussion is a type of traumatic brain injury that changes the way the brain normally works. A concussion is caused by a fall, bump, blow, or jolt to the head or body that causes the head and brain to move quickly back and forth. A concussion can be caused by a shaking, spinning, or a sudden stopping and starting of the head. Even a "ding," "getting your bell rung," or what seems to be a mild bump or blow to the head can be serious. A concussion can happen even if you haven't been knocked out.
You can't see a concussion. Signs and symptoms of concussions can show up right after the injury or may not appear or be noticed until days or weeks after the injury. If the student reports any symptoms of a concussion, or if you notice symptoms yourself, seek medical attention right away. A student who may have had a concussion should not return to play on the day of the injury and until a health care professional says they are okay to return to play.
