Symptoms

A concussion is a brain injury that:

  • Is caused by a bump, blow, or jolt to the head or body
  • Changes the way your brain normally works
  • Occurs during practices or games in any sport or recreational activity
  • Happens even if you haven’t been knocked out
  • Can be serious even if you’ve just been “dinged” or “had your bell rung.” All concussions should be taken seriously. A concussion can affect your ability to do schoolwork and other activities (such as playing video games, working on a computer, studying, driving, or exercising). Most people with a concussion get better, but it is important to give your brain time to heal.

Signs and symptoms of a concussion:

You can’t see a concussion. Signs and symptoms of a concussion can show up right after the injury or may not appear or be noticed until days after the injury. If your child reports one or more symptoms of concussion listed below, or if you notice the symptoms yourself, keep your child out of play and seek medical attention right away.

Confusion Feeling “in a fog”, “zoned out”
Post-Traumatic Amnesia (PTA) Vacant stare, “glassy eyed”
