title: [Possible identification of electroencephalographic changes caused by hereditary and process factors in schizophrenia].
abstract: A comparative study of the quantitative differences of EEG parameters in the pairs of mono- and dizygotic twins suffering from schizophrenia has shown that the magnitudes of some parameters were substantially lower in the monozygotic twins than in the dizygotic ones. Examinations of healthy relatives of the schizophrenic twins revealed an increased frequency of the same signs (in the magnitude and direction), as in the patients. Less distinct in the mono- dizygotic pairs were differences between the reactive changes of the biopotentials and the latter's spatio-temporal organization inside the pairs. In the monozygotic pairs, these changes and organization were disturbed to a greater degree in the twin partner with a more rapid progress of the disease.
