[Epidemiology, clinical aspects and prevention of borderline conditions in the regions of Siberia and Far East].

The problem of borderline conditions in the population of Siberia and the Far East is analyzed from the standpoint of a comprehensive multidisciplinary approach. The authors established the indicators, close to the real ones, of the prevalence of borderline disorders, exceeding many times the formal statistic data. Evidence is given of the role of certain personality parameters (rigidity, anxiety) and biological factors (the status of the immune and hormonal systems) in the formation and course of borderline conditions. The clinical studies carried out over time made it possible to specify definite stages in the development of borderline pathology. 3 stages were delineated: initial disorders or reactions; neurotic or neurosis-like conditions; neurotic or pathological developments of the personality. The authors demonstrate imperfection of the existing systems of psychiatric aid in respect to patients with borderline disorders and provide evidence for the necessity of organizing psychiatric services outside dispensary aid. Novel organizational models (the center for borderline conditions, the center for mental health care at industrial enterprises, municipal psychohygienic consultation) developed by the authors are provided as prognosis. These structures made it possible to enhance the efficacy of prevention and treatment of borderline conditions.
