“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. Rapid movement causes brain tissue to change shape, which can stretch and damage brain cells. This damage also causes chemical and metabolic changes withinthe brain cells, making it more difficult for cells to function and communicate. Since the brain is the body’s control center, the effects of a concussion can be far-reaching.

Concussions are usually not life-threatening, but the effects of a concussion can change a life and the injury should be treated seriously”.
