Traumatic Brain Injury

Background

A traumatic brain injury (TBI) is defined as a blow or jolt to the head or a penetrating head injury that disrupts the function of the brain. Conscussions, also called “closed head injuries”, are a type of TBI. Not all blows or jolts to the head result in a TBI. The severity of such an injury may range from “mild”, i.e., a brief change in mental status or consciousness to “severe”, i.e., an extended period of unconsciousness or amnesia after the injury. TBI can cause a wide range of functional changes affecting thinking, sensation, movement, language, and/or emotions. Some symptoms may appear immediately after the injury and other symptoms may not appear for days or weeks. Because of the nature of the injury and the symptoms, sometimes people may not recognize or admit that they have a problem. In post-concussion/mild TBI patients, recovery time is within weeks/months, but a small percentage have persistent symptoms. Patients with moderate to severe TBI may never fully recover their pre-injury function. The rate of combat-related brain injuries in servicemembers returning from the current conflicts in Iraq and Afghanistan is higher than in previous conflicts. Blast injuries are a significant cause of TBIs. TBI is often associated with severe multiple trauma, post traumatic stress disorder (PTSD) or undiagnosed concussions. Screening patients who are at risk for a TBI is important in order to ensure that TBIs are identifed and appropriately treated.
