Traumatic brain injury is a common neurologic condition that can have a significant emotional and financial burden. Neurologic injury is classified on the basis of initial clinical status by the Glasgow Coma Scale, and also by the type and location of head injury. Complications in the management of these patients are reviewed, ranging from intracranial pressure management and stroke to post-traumatic epilepsy. In addition, predictive prognostic variables that can be used to predict outcome based on a patient's presentation at the time of a head trauma are discussed. Finally, interventions such as induced hypothermia that can be undertaken to try to optimize outcome, are discussed along with current data in support of or against such techniques.
