Persistent neuropsychological deficits in cervical whiplash patients without direct headstrike.

Persistent cognitive and neurasthenic complaints can be the consequence of a cervical whiplash injury. In contrast to otoneurological and orthopedic reports, neuropsychological studies on whiplash patients are scarce. We report disturbances of information processing and memory functions in two patients with a pure cervical whiplash injury with demonstrated central otoneurological abnormalities, whereas there was no evidence of intellectual deterioration or focal cortical deficits. The results suggest that the cognitive disturbances and neurasthenic symptoms may be part of one syndrome which appears to manifest itself under conditions of time pressure and distraction.
