[The drama of hyperextension trauma--chronic whiplash syndrome with its neuropsychological and psychiatric findings. An analysis of 80 cases from expert assessment].

The problem "whiplash associated disorder" was studied in a multidisciplinary analysis of 80 patients who all had a "simple whiplash-accident", this means a whiplash-accident without concomitant head trauma apart from contact with the car seat and without unconsciousness. The opinions of a rheumatologist and of a psychiatrist were considered in each case, and in 47 patients, a neuropsychological expertise was present. 43% of the patients who had been neuropsychologically tested revealed specific cognitive deficits as they are described after mild traumatic brain injuries and after whiplash accidents. Symptoms related to a pretraumatic cognitive disease were not found in any of the cases. Most patients had been professionally active at the time of the accident, some performing activities requiring a high level of cognitive skill. 66% percent of the study group showed psychological disturbances reducing the working capacity. There was no evidence for preexisting traumatic psychiatric symptoms. In many cases the psychiatric disturbances were accident-related, either reactive to the cognitive deficiencies or resulting from chronic pain. We assume that the "simple whiplash-accident" can cause chronic disturbances of brain function. In the etiology, a mild traumatic brain damage must be considered, this means an organic damage and not only a functional brain disorder. These brain function disturbances are often masked by the pure psychiatric symptoms, therefore they must be carefully searched for. Injured patients, who do not regain their working capacity after the accident, should be explored in a neuropsychological as well as in a psychiatric mode as early as possible after the accident.
