What is a Concussion?

A concussion is a type of traumatic brain injury, or TBI, caused by a bump, blow, or jolt to the head that can change the way your brain normally works. Concussions usually happens when a force, blow or hit moves your body in a way where your head jerks rapidly back and forth. Small hits, dizzy hits and bouncing your head against a tough surface can cause a concussion and could be reason for alarm.

Whether you’re playing soccer, football, hockey, or volleyball, concussions can happen. Being prepared or having teammates, coaches, and parents who understand how to treat concussions is vital.
