[Epidemiological characteristics associated with alcoholism in schizophrenics]

Schizophrenic patients residents of the city of Tomsk and Tomsk Province were studied at first admittance to the Tomsk Psychiatric Clinic in 1948 to 1951 (1st period), 1959 to 1961 (2nd period), 1969 to 1971 (3rd period), 1979 to 1981 (4th period). In each of the 4 periods cases were detected with apparent alcoholization preceding or coinciding with the onset of schizophrenic signs. Intensive indices (per 10,000 population) of the 1st hospitalization of patients with schizophrenic signs. Intensive indices (per 10,000 population) of the 1st hospitalization of patients with schizophrenia and alcoholism were significantly different for the 1st and 4th periods (0.026 and 0.51 respectively). Clinical analysis revealed the hallucinatory-paranoid symptoms to be most common for these patients.
