What is a Concussion?

brainscanA concussion is a traumatic brain injury. It doesn’t matter if you’re an athlete or not; if untreated, a concussion can result in serious, sometimes permanent damage. Symptoms can begin right away or a few days after the concussion.

Why is concussion so dangerous?

A concussion can cause significant impairment without the person losing consciousness. If a second concussion occurs before the first one has passed, serious or permanent cognitive, behavioral and physical changes can occur.
