ReviewMultimodal neuroimaging approaches to disorders of consciousness.
Advances in neuroimaging techniques hold significant promise for improving understanding of disorders of consciousness arising from severe brain injuries. We review neuroimaging studies of the vegetative state (VS) and minimally conscious state (MCS), and findings in an unusual case of late emergence from MCS. Multimodal neuroimaging studies using positron emission tomography techniques, functional magnetic resonance imaging, and quantitative electroencephalography and magnetoencephalography quantify variations of residual cerebral activity across these patient populations. ⋯ More generally, relatively long time courses of recovery following severe brain injury emphasize the need to develop markers for identifying patients who may harbor potential for further meaningful recovery. Introduction of neuroimaging into the clinical evaluation process will require developing frameworks for longitudinal assessments of cerebral function. Although limited in number, available studies already provide important insights into underlying brain mechanisms that may help guide development of such assessment strategies.

Traumatic brain injury (TBI) is an important source of morbidity in the Iraq and Afghanistan wars. Although penetrating brain injuries are more readily identified, closed brain injuries occur more commonly. Explosion or blast injury is the most common cause of war injuries. ⋯ Lessons learned from the sports concussion and civilian mild TBI literature are useful. Individuals with TBI and posttraumatic stress disorder require treatment of both conditions. Families and communities need to be cognizant of the needs of these returning veterans.

ReviewThe use of serum biomarkers to predict outcome after traumatic brain injury in adults and children.
Traumatic brain injury (TBI) is a leading cause of morbidity and mortality in adults and children. Predicting outcome after TBI is difficult, but it is important for acute management, counseling of family members, and provision of rehabilitation services. Serum biomarkers may be useful alone or in combination with clinical variables to predict outcome after TBI. This article reviews the potential uses of serum biomarkers for the clinician, current literature related to the use of serum biomarkers for outcome prediction after adult and pediatric TBI, limitations of the literature, and future direction for this field.

Causes of death following 1 year postinjury among individuals with traumatic brain injury.
To investigate causes of death in individuals with traumatic brain injury (TBI). ⋯ Long-term follow-up of individuals with TBI should increase vigilance for, and prevention of, diagnoses frequently causing death (circulatory disorders) and diagnoses with a high relative risk of causing death in this population (seizures, septicemia, respiratory and digestive conditions, and external causes of injury).
