Traumatic Brain Injury

Traumatic brain injury 

                    (TBI) is a nondegenerative, noncongenital insult to the brain from an external mechanical force, possibly leading to permanent or temporary impairment of cognitive, physical, and psychosocial functions, with an associated diminished or altered state of consciousness.

   

           There are several ways to describe brain injuries. The brain is enclosed in the bony vault of the skull. The cerebrospinal fluid surrounds the brain and, most of the time, protects it from impact with the skull. If there is a rapid force applied to the skull or rapid deceleration of the head, the brain may strike the inside of the bony vault.

Brain tissue may stretch or tear because of the rapid movement. This can injure the nervous tissue of the brain directly. If a projectile such as a bullet enters the skull, it can directly injure the brain.

Below is a list of terms and definitions that refer to the different injuries of TBI.

Closed Head Injury  the skull is intact and there is no penetration of the skull. Direct or indirect force to the head can cause this type of injury. This may be caused by rotational and/or deceleration in the case of both direct and indirect force.
