Abstract

Patients with obstructive sleep apnea syndrome suffer from reduced continuous attention due to neuropsychological deficits. Among other means, driving simulator programs are employed for registration and objectification as well as observation of the course of therapy. While Steer Clear by Findley et al. and the driving simulator Carda (Randerath et al.) represent pure continuous attention tests, the new driving simulator test Carsim, measures attention interactively and continuously. This way, more complex functions are recorded. We therefore investigated Carda and the program Carsim to study the various features of both methods. For this purpose, 105 OSAS patients were tested on both driving simulators concerning the mistake rate in Carda and the time of tracking deviations in Carsim. We defined the normal range by using the mean value +/- 2 standard deviations from our earlier publications in healthy persons without sleep disorders. With Carda the mistake rate exceeded in 10 of 105 patients (9.5%) the normal range and with Carsim the frequency of tracking deviations exceeded in 49 of 105 patients (46.7%) the normal range. The incidence of deviation from normal was significantly higher with Carsim testing. By additionally testing the number of pathological cases is with Carda increased from 46.7% to 51.4%. The tests characterize different components of neuropsychological deficits. Driving simulators with tracking tasks describe neuropsychological deficits in comparison with those measuring only components of reaction in a higher percentage.
