Abstract
Neuropsychological test performances of 102 consecutive head-injured patients were evaluated at 1 mo and 1 yr after injury. The results of the study indicated that both coma length and the presence of focal abnormalities on computed tomography (CT) scans contribute independently to neuropsychological outcome. The effects of coma length are stronger than the effects of focal abnormalities evident on CT scans and continue to exert a stronger influence on neuropsychological outcome over the year postinjury. These results suggest that the extent of diffuse pathology may be a more important determinant of long-term behavioral outcome than the presence of focal lesions.
