Traumatic Brain Injury

What Is A Traumatic Brain Injury?

Traumatic brain injury is a sudden physical damage to the brain. The term does not apply to brain injuries that are hereditary, congenital, or degenerative. Traumatic brain injury is an injury that is manifested by one or more of the following:

  1. loss of consciousness;
  2. memory loss of events immediately before or after the accident;
  3. alteration of mental state at the time of the accident such as feeling dazed, disoriented or confused, and alteration of mental state;
  4. focal neurological deficits that may or may not be temporary.

How Is Traumatic Brain Injury Caused?

The damage may be caused by the head forcefully hitting an object, such as when hitting a windshield or the dashboard of a car, or by something passing through the skull and piercing the brain. A closed head injury may also be experienced without direct penetration of the skull or external trauma when the brain undergoes a severe forward or backward shaking or twisting.
