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.

TBIs can result from any external force or penetrating injury to the head. Here’s what commonly causes TBIs and what victims can do to seek justice after suffering a TBI.

Usefulness of DTI in Traumatic Brain Injury Patients

Traumatic brain injury (TBI) and mild traumatic brain injury (mTBI) are commonly referred to as a concussion. The diagnosis of concussions remains controversial, seeing as how the brain often appears quite normal on conventional computed tomography (CT) and magnetic resonance imaging (MRI) scans. Before-Mentioned conventional tools, still, do not adequately depict brain injury especially in mTBI patients because such conventional tools are not sensitive in detecting diffuse axonal injuries (DAI), also described as traumatic axonal injuries (TAI), which are major brain injuries in mTBI cases. Moreover, 15 to 30 % of those diagnosed with mTBI on the basis of cognitive and clinical symptoms, do not settle following the first three months post-injury. Rather, cognitive and clinical symptoms persist, and in some cases lead to long-term disability.i
