[Prognosis of the frequency of attacks of schizophrenia (according to findings from an epidemiologic study)].

In 915 patients with attack-like schizophrenia with a duration of the disorder not less than 15 years, the authors studied some clinical and endogenous factors in order to determine the criteria of prognosis of the attacks. It was displayed that in most of the cases schizophrenia proceeded with a small amount of attacks. Manifestation at young age (irrespective of the duration of the disorder), its affinity to the periodical pole of the disorder and concomitance of subsequent attacks of manic disturbances correlated with a large amount of attacks.
