Studies of mild traumatic brain injury (MTBI) suggest that most individuals recover rapidly and return to their everyday activities. However, a percentage of MTBI patients report persistent problems with cognitive, physical, and emotional symptoms. There is also evidence that some experience changes in occupational functioning following MTBI. The current study used a stepwise discriminant function analysis (DFA) to examine the role of injury severity variables, cognitive performance, and ratings of symptoms of TBI in predicting work status following MTBI. Subjects included 121 MTBI patients who were all active-duty military personnel. The stepwise DFA revealed that age and three cognitive variables (verbal memory, verbal fluency, and a speed test of planning and strategy) were predictive of work status 3-15 months following a documented MTBI, correctly classifying work status 68.8% of the time. A cross-validation DFA was conducted, with a 66.1% correct classification rate. These findings highlight the importance of cognitive impairments in identifying those at risk for occupational impairment following MTBI.
Traumatic brain injury (TBI) is the leading cause of death in children in the United States. Each year 37,200 children sustain a severe TBI, with up to 1.3 million life-years potentially adversely affected. Severe pediatric TBI is associated with significant mortality and morbidity. Of the children who survive their injury, more than 50% experience unfavorable outcomes 6 months after the injury. Although TBI-associated death rates decreased between 1997–2007, disabilities for TBI survivors continue to have both a direct and indirect impact on the economic and human integrity of our society. The degree of disability varies with the severity and mechanism of the injury, but a realm of physical and emotional deficits may be evident for years after the injury occurs. This article describes the pathophysiology of moderate to severe TBI, its associated complications, and opportunities to improve patient outcomes through use of acute management and rehabilitation strategies. To address the many challenges for TBI survivors and their families, including significant financial and emotional burdens, a collaborative effort is necessary to help affected children transition seamlessly from acute care through long-term rehabilitation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
