title: Driving simulator performance and psychomotor functions of schizophrenic patients treated with antipsychotics.
abstract: The objective of the study is to compare schizophrenic inpatients under antipsychotic monotherapy regarding simulated driving behaviour and psychomotor functions related to driving ability. Schizophrenic inpatients (n = 80) were tested before discharge to outpatient treatment. Data were collected with the computerized Act & React Testsystem and the Wiener Testsystem measuring visual perception, reaction time, attention, vigilance and stress-tolerance. Besides, patients underwent various driving simulations on a static driving simulator (FT-SR 200). Before discharge to outpatient treatment, about 25% of schizophrenic patients must be considered as severely impaired with respect to driving skills. Differences between treatment groups could be shown both in psychomotor measures and in driving simulator performance with a better test performance of patients treated with atypical antipsychotics. Controlling for age, psychopathologic symptoms and extrapyramidal signs, differences in psychomotor measures were most pronounced in concentration and vigilance. As mental disorders itself pose an increased risk of accidents, counselling patients with respect to differential effects of antipsychotic treatment is of great relevance. In addition to psychomotor tests computer-simulated driving seems to be a useful tool in assessing traffic safety under pharmacologic treatment.
