Traumatic brain injuries (TBIs) can result in temporary or permanent damage to very important functions of the brain. TBI is a wide-ranging term that includes various types of debilitating impacts on the brain. This type of injury can affect the entire brain or just one isolated area. During a car accident, an individual may suffer a TBI that is a closed head (internal) injury or one that involves an open head injury in which the skull is shattered or pierced. TBIs can produce loss of consciousness for extended periods of time and even comas that last weeks or longer.


A concussion is a type of mild traumatic brain injury and is the most common type. According to the Alabama Department of Rehabilitation, concussions account for about 75% of TBIs. An individual who receives a blow to the head in one way or the other has the potential to sustain a concussion. In some cases, this can result in a loss of consciousness for a brief period of time. Additional symptoms of a concussion can include loss of balance, slurred speech, confusion, blurry vision, and vomiting. The nature of the symptoms determines a doctor’s diagnosis of a concussion as mild, moderate, or severe.


If the head is violently shaken or hit, the brain may ricochet against the inside of the skull and suffer bruising. When the brain tissue is bruised in such an event it is referred to as a cerebral contusion. With a contusion, bleeding occurs in the area of the brain that sustained the impact. As the days pass after the initial impact, the contusion may expand and exert pressure on the brain, negatively affecting brain function. Some large contusions require surgery to fix.

Diffuse axonal injuries

Widespread injury to the brain’s nerve fibers is referred to as a diffuse axonal injury. When the head rapidly accelerates and decelerates, the nerve fibers called axons that deliver nerve signals can shear or tear. This type of injury causes disruption to the brain’s communication grid. Car crashes among other violent incidents commonly lead to diffuse axonal injury. Victims of this brain injury often lose consciousness for at least six hours and sometimes suffer brain damage. The injury can become more severe if brain swelling occurs and increases pressure inside the skull, restricting the blood supply to the brain.

Penetrating head trauma

A penetrating head injury occurs when a blunt or sharp object, such as a nail, knife, bullet, or screwdriver penetrates the skull. Gunshot wounds often cause this type of injury.

Coup-contrecoup injury

A coup-contrecoup injury occurs in certain types of higher velocity or blunt force accidents. In these accidents, the impact causes the brain to strike one side of the skull and then move the opposite direction to strike the other side of the skull. This injury can produce bruises on both sides of the brain.
