The brain is surrounded by cerebrospinal fluid, one of the functions of which is to protect it from light trauma, but more severe impacts or the forces associated with rapid acceleration may not be absorbed by this cushion.[10] Concussion may be caused by impact forces, in which the head strikes or is struck by something, or impulsive forces, in which the head moves without itself being subject to blunt trauma (for example, when the chest hits something and the head snaps forward).

Relationship Between Whiplash and Concussion

It is obvious that during a whiplash event that, in addition to the soft-tissue neck injuries that there could be direct contact of the head on an unforgiving surface. A blow to the head can produce jarring, shaking, or excessive movement of the brain inside the skull. This would be a logical circumstance in which concussion could occur. But what about situations in which there is whiplash yet there is no direct contact of the head on any surface? The high velocity movement of the head during a whiplash event alone could produce the same effects. One example of this phenomenon occurred recently to an athlete in American professional baseball playing for the Milwaukee Brewers in Major League Baseball. In 2006, Corey Koskie suffered a concussion without a direct force to the head during a routine play in the field. While attempting to catch a ball batted in the air into shallow left field, he fell backward, landing on his upper back. The force of the fall did not cause his head to hit the playing surface but produced a whiplash-like force at the cervical spine. At this point, Koskie has missed two and one half baseball seasons because of concussion-like symptoms and his progress has been atypically slow. Victims of motor vehicle accidents have the potential for a similar response to a whiplash mechanism of injury. Recognition of the potential for these scenarios is important for proper treatment of the injured athlete or accident victim.
I just have to say that this is a pretty good writeup on concussions. I agree that a hit to the jaw can cause a concussion, as can an accident where your head doesn't touch anything. Anytime inertia of the brain occurs there is a chance for concussion.
