Half of concussions are caused by sports, but half are caused other accidents such as falls or car accidents. People of any age can get concussions if their head is violently moved.

If you think you have a concussion, a trained team will assess you and see how well your brain is working. Resting your brain is the main treatment. If you're having trouble with balance, dizziness or poor vision, you may also have vestibular therapy to help your brain.

It can take weeks or months to get over a concussion; children and young teens take less time to recover than older teens and adults do.
