Traumatic Brain Injury (TBI) is a sudden impact to a person’s head or body resulting in damage to brain functioning. Examples of TBI include concussion, brain contusion and hematoma (bleeding inside or near the brain).
According to the Centers for Disease Control, 2.5 million cases of TBI were reported in the United States in 2010.
The most common form of TBI is a concussion. It is defined as a brief loss of normal brain function due to impact of the head.
