[Classification and psychological prevention of pre-nosological forms of borderline conditions occurring in the Northern Siberia].

Based on the clinico-epidemiological and clinico-dynamic++ examination of the workers (n = 2,052) of one of the lumber industry plant a concept was advanced concerning the influence the extreme climatic,+-geographical, industrial and other factors produce on the formation of unusual psychodisadaptation conditions (PDAC). They appear as polymorphous, syndromologically incomplete neuropsychic deviations. Three PDAC varieties have been distinguished: asthenic (with two subtypes mirroring the predominance of physical or mental weakness), dysthymic and psychovegetative. Each of these varieties has been characterized in detail from the typology standpoint. Programs aimed at PDAC prevention have been elaborated. They include the use of psychoprophylactic, psychotherapeutic psychopharmacological measures combined with physiotherapy and reflexoprophylaxis. It is suggested that specialized psychoprophylactic services should be organized for persons with the pre-nosological++ and initial manifestations of border-line diseases that form under the given ecological conditions.
