[Experience with a differentiated clinical approach to epidemiologic description of populations of schizophrenic...

Data on the frequencies of various schizophrenia forms among the population of three districts of Moscow are presented. These data were obtained from direct examinations of each schizophrenia case, and are the most differentiated clinically, as compared with those reported in earlier publications. With regard to one district of Moscow a more detailed information is presented: such as, the frequency of admission for schizophrenia to psychiatric hospitals that was found to be 9.63 per 1,000 of population, 9.85 for males and 9.48 for females. The admission frequency for continuously-progressing cases was 2.51; for paroxismally-progressing ones 5.26; and for recurrent cases 1.80. In addition to these figures data on the admission frequency with regard to the underlying syndrome at the manifest stage of the disease (within the range of the above-mentioned basic forms of the disease course) are presented. Also the frequencies of various forms of the disease onset and the duration of the patients' stay in hospital and their observation by psychiatrists at home are analyzed with reference to the disease pattern and the frequency of each patients's hospitalization.
