[Mental disorders during and after natural disasters and catastrophies].

Analysis is made of mental disorders seen in 3431 victims followed up by psychiatrists in 11 large-scale catastrophies and natural disasters. Three periods of the development of the life-threatening situation were distinguished, during which one can see different states of mental disadaptation and morbid disorders. The clinical picture of such disorders is provided.

[Mental disadaptation in emergency situations (accident at the Chernobyl nuclear power station)].

Phenomenology and time course of psychic disorders in persons exposed to life-threatening emergency situations provoked by the Chernobyl accident have been analyzed. Three states could be identified according to differences in their psychogenic impact: acute, delayed and long-term. Psychic dysadaptation and disorders might be presented as results of a single process beginning with acute anxiety responses followed by asthenic disorders which backed the relatively steady neurotic and psychopathic states.

[Attempt at categorizing the hospitalizations of schizophrenics and evaluation of the effectiveness of measures to prevent them].

The case reports of 150 schizophrenic adults over a period of ten years were analyzed. The study was based on a series of clinical-biological, "microsocial" and "psychosocial" parameters and covered 742 hospital admissions and the same number of interhospitalization periods (IHP). Such factors as "syndrome", "alcoholization", "system of interpersonal (intrafamilial) relations" were found to have the greatest impact on the behavioural pattern leading to hospitalization.
