[Schizophrenic syndromes and efficacy of unilateral electroconvulsive therapy].

The authors compared the efficacy of unilateral electroconvulsive therapy in schizophrenia in relation to the leading syndrome and the place of electrode application. In controlling the affective and catatonic syndromes the best effect was achieved when the electrodes were applied to the non-dominant hemisphere. In delirious, hallucinatory-delirious and hallucinatory syndromes, the maximal effect was achieved by the application of electrodes to the dominant hemisphere. The relationship between the effect of local electroconvulsive therapy and the semiotics of the syndromes allows making the most rational use of unilateral electroconvulsive therapy in the differential treatment of schizophrenia.
