Concussions are brain injuries. They are caused by a bump or blow to the head. Even a mild bump or blow can be serious.

Look for any of these symptoms: appears dazed or stunned, confusion, forgetful, moves clumsily, loses consciousness (even briefly), can't recall events prior to or after the injury, headache, nausea, vomiting, blurry vision, sensitivity to light or noise, and feels foggy.

Seek medical attention right away. A health care professional will be able to decide how serious the concussion is.
Keep your child out of play. Concussions take time to heal. Children who return to play too soon risk a greater chance of having a second concussion which can cause permanent brain damage. Tell your child's coach or teacher about any recent concussion. A plan will be developed as when your child can safely participate.
