Neuropsychological and psychosocial consequences of minor head injury

Twenty subjects with minor head injury were compared to an uninjured group at 1 and 12 months after injury on a battery of neuropsychological and psychosocial measures. The results indicate that single minor head injury in persons with no prior compromising condition is associated with mild but probably clinically non-significant difficulties at 1 month after injury. Disruptions of everyday activities, however, are extensive with other system injuries significantly contributing to these problems. Recent reports in the literature may represent overestimation of head injury related losses due to lack of control for the effects of pre-injury characteristics and other system injuries.
