Current epidemiological data indicate that head injury is the most common acute neurological disorder in the United States (Kraus & Sorenson, 1994). These data also indicate that head injuries vary considerably in severity. Although a number of alternative indices are available, the most well-accepted indicator of initial head injury severity is the Glasgow Coma Scale (GCS), which quantifies disturbance of consciousness on a scale ranging from 3 to 15 (Eisenberg & Weiner, 1987). Head injuries producing GCS scores in the moderate (9–12) to severe (3–8) range often involve significant morbidity or mortality (Adams & Victor, 1993). Head injuries resulting in GCS scores of 13–15 are classified as mild, and approximately 80% of all head injuries fall in this category (Kraus & Sorenseon, 1994). In contrast to the outcome literature on moderate to severe head injury, the largest and best-controlled studies to date suggest that by 1 year postinjury, neuropsychological and psychosocial outcome for patients suffering an uncomplicated mild head injury (disturbance of consciousness lasting no more than 1 hour and no other indicators of neurological disturbance) is comparable to that experienced by patients suffering general trauma not involving brain injury (Dikmen, Machamer, Winn, & Temkin, 1995; Dikmen, Ross, Machamer, & Temkin, 1995). Of course, the general trends observed in group studies, however methodologically sound, do not preclude the possibility of poor outcome in selected individual cases. Nonetheless, the scarcity of such cases in large well-controlled outcome studies should sound a cautionary note in a situation where a patient with a history of mild head injury without neurological complications complains of severe disabilities.
