Traumatic brain injuries can occur in car accidents in a number of different ways. For example, the head may collide with the airbag or be pierced by a projectile. It is possible for other bodily injuries to lead to brain damage, such as a broken trachea that deprives the brain of oxygen. This article discusses the different mechanisms of brain injury in car accidents and their effects on the brain.
Coup-contrecoup is a term used to describe a particular mechanism of brain injury in whiplash and similar traumatic scenarios. When the head whips back and forth and/or collides with an object, the brain moves inside the skull. This causes the brain to collide with the skull.
