What is a concussion?

A concussion is a brain injury caused by a bump or blow to the head. Even what seems to be a mild bump or blow to the head can be serious.

You cannot see a concussion. Signs and symptoms may show up right after the injury, or they may not be noticed until days or weeks later. If you or your loved one reports any symptoms of a concussion that last longer than two weeks, please make an appointment with the Concussion Clinic. We see patients with concussions caused by a variety of ways. Common causes include sports-related injuries, motor vehicle accidents, work-related injuries, and falls.
