TBI may be the result of a variety of accidents and occurrences. First, TBI can result from direct blows to the head, gunshot wounds, violent shaking of the head, or by force from a whiplash sort of injury. Secondly, TBI is seen in cases of concussions, produced when the brain experiences trauma from an impact, sudden momentum or movement change, and, as a result, the blood vessels in the brain stretch and the cranial nerves can become damaged.
Some concussions can cause a blood clot in the brain to form, becoming fatal. Concussions can take a few months to a few years to fully heal. Moreover, TBI can be a contusion resulting from a direct impact to the head, causing bleeding within the brain. TBI can also be a diffuse axonal injury that is typically caused by shaking or a strong rotation of a person’s head, which is most commonly seen with Shaken Baby Syndrome, or by rotational forces, such as a car accident. Finally, TBI can be the result of a penetrating injury to the brain occurring from the impact of a bullet, knife or other sharp object that forces hair, skin, bones and fragments from the object into the brain. TBI is the effect of a variation of accidents and incidents.
