What is Concussion?

What is concussion?

The brain floats inside the skull, suspended within a protective cushion of cerebrospinal fluid. A direct blow to the head, face or neck, or from an impact to somewhere else on the body, can create a force that shakes the brain. When that force is strong enough, or comes from a particular direction, the brain can move so that it strikes the skull or twists upon itself. Just as for any body part that is struck, bruising and cell damage can occur. When those cells are neurons, however, concussion is the outcome. Because the brain is so central to our lives, controlling mood, perception and movement, the effects of concussion can be far reaching.
