A neuropsychiatric perspective on traumatic brain injury

Warren E. Lux, MD

This article is about what happens to the brain when a person has a closed-head traumatic brain injury (TBI). It covers mild injuries, which are called concussions, as well as injuries that are more severe and describes the kinds of changes in thinking, emotions, and behavior that can result. A common feature of TBI is that it often affects an individual's ability to use a function in the real world as much or more than it affects the primary function itself. Also, we must remember that TBI needs to be understood as a condition that affects not just an individual but also the individual's interaction with all other persons and things in his or her environment. Thus, treatment needs to consider the environment as well. People who may benefit from reading this article include persons who have had closed-head injuries and their families, particularly if the person with the injury is having changes in thinking or behavior that seem difficult to understand or explain. This article will help them understand how the TBI can cause these changes.
