A concussion is an brain injury caused by any blow to the head, face or neck, or somewhere else on the body which results in a sudden jarring of the head. A concussion can’t be seen on routine x-rays, CT scans or MRIs.

You don’t have to lose consciousness to have a concussion. Signs and symptoms may be immediate or delayed for a period of time, and sometimes symptoms can be subtle and may not be noticed. Without identification and proper management, a concussion can result in permanent or severe brain damage.

Signs and symptoms of a concussion often last for 7 to 10 days or may last longer, even weeks or
months. The most important initial treatment for a concussion is both physical and mental rest. That means no exercising, bike riding, playing video games, reading or working on the computer.

All Ontario school of boards have a comprehensive concussion policy that requires assessment and approval from a healthcare provider to return to school and physical activity.
