Using modern genetico-mathematical methods (genetico-correlational analysis), the author made a comparative analysis of the findings from a clinico-genealogic study of two groups of probands--with torpid schizophrenia (192 families) and with manifest forms of schizophrenia (365 families). The results obtained confirm the validity of the clinical differentiation of torpid schizophrenia as one of relatively independent forms of schizophrenia.
