[Modification and improvement of the diagnosis of cerebral damage (DCS) for clinical use (author's transl)]

The purpose of this study was to determine whether Weidlich's DCS Test (Diagnostikum für Cerebralschädigung) (Weidlich, 1969) which is very burdensome when applied to brain-damaged patients, could be simplified by means of multivariate error analysis without loss of its great diagnostic value. The results of 40 brain-damaged patients and 47 clinical control patients were examined by multivariate analysis. In order to establish a comparative learning-function value, a random sample of 20 nonclinical persons was tested, as well. Results showed that within a discriminant function the error variables could differentiate clinical groups just as well as Weidlich's global criterium, while a diagnosis could be established after only about half the test time. Applicability of the multivariate methods to the diagnosis of single clinical cases was confirmed by means of positive cross validation.
