Abstract: | In a group of 44 children with behaviour disorders, the mode of action of the phenothiazine preparation fluphenazine hydrochloride (Lyorodin) was tested by means of psychophysiological methods of measurement (critical flicker-fuse frequency and measurement of the response time). In some of the comparative examinations before and after administration of the drug significant differences were found. A defined psychic stress resulted in changed measured values in both methods. Children with cerebral injuries showed a lower degree of reaction after the administration of the preparation than children not encephalopathically affected. |
