Understanding Concussions Part 2: Returning to Sport and Prevention

About 41 percent of student athletes who have sustained a concussion will return to sport prematurely. This can be very dangerous because it can lead to something called second impact syndrome, which is often fatal.
A concussion is a type of traumatic brain injury caused by a bump, blow, or jolt to the head or by a hit to the body that causes the head and brain to move rapidly back and forth. The resulting trauma from this sudden movement can cause damage to the brain cells.
