[Early criteria for the social and occupational prognosis of patients with periodic schizophrenia].

A total of 193 patients suffering from periodic schizophrenia for a long time (over 20 years) and living in Moscow and Andijan were exposed to a clinical and epidemiological survey. Criteria of early social and work prognosis, both common and specific for each population, were eliminated. The lack of the pathological premorbid and mental activities are prognostically benign signs for both populations, while schizoid traits and low educational level are regarded as unfavourable. In the Moscow population, the prognostically benign sign was the educational level while the unfavourable one was unskilled labour. As regards the Andijan population, the benign manifestations included secondary education and marriage by the disease commencement, whereas the unfavourable sign was no marriage.
