What are the most common causes of TBI in motor vehicle accidents?

A motor vehicle accident may cause occupants to suffer traumatic brain injuries in various ways. Getting jostled around in a crash can cause a TBI as the brain impacts the inside of the skull. Jerking of the head or body can impart twisting forces on the brain that damages neurons and causes a diffuse axonal injury. Finally, debris or shrapnel from a crash can penetrate a car accident victim’s head, break the skull, and cause physical trauma to brain tissue.
