[Prognostic criteria of depression].

Based on a structural dynamic analysis of the development of the depressive syndromes of varying nosology the psychopathological predictors of the disease duration and quality of the outcome from depression were distinguished. Criteria for harmonicity and structural complexity of the depressive condition were attributed to those predictors. The correlation was found between the syndrome structure and the levels of the ensuing remission. The use of an electrooculographic study allowed an objective evaluation of the expected outcome of depressions.

[Age and features of depressions during the 2d half of life].

On the basis of a psychopathological analysis of 207 patients at the age from 45 to 80 years suffering from depressions of different nosology the authors have shown that along with common signs characteristic of the age of involution such as a considerable involvement of anxiety in the affective link, asthenic disorders, a decrease in the physiological tonus, body sensations, etc., there are significant internosological differences. These include a tendency toward the typization of depressive phases and attacks in the framework of endogenic diseases on the one hand and more classical structures of depressions characterizing psychogenic and vascular diseases corresponding to the traditional notions on the other hand.

[Visual perception disorders in depressive syndromes].

A wide range of psychopathological visual phenomena, part of which are traditionally considered as derealizational disturbances, are described in the structure of depressive states. Five main types of disordered visual perception are singled out, which differ by their structure and degree of correlation with the depressive affect and symptoms of depersonalization in a wide sense. The results point to certain dynamics in the described phenomena, their sensory basis. Electrooculographic studies of eye movements indicating a peculiar formation of a visual image in different forms of depressions are demonstrated.

[Certain patterns in the formation of optical illusions].

A structural dynamic analysis of productive disorders in visual perception was attempted on the basis of psychological study of 344 patients. These disorders were studied according to the increasing degree of inadequacy (anisomorphia) of pathological images in respect to real stimula. Considering the differences of such phenomena according to the degree of discrepancy of their perceptive characteristics with the traits of real objects, some successively complicated pathological images were examined, including traditional false recognition, illusions and hallucinations, as well as interlapping intermediate structures. Some pathogenetical mechanisms in the formations of visual illusions are suggested. Clinico-psychopathological parallels are made between disorders of visual perception and disease entities.

[Psychopathologic structure of protracted endogenous depressions].

The psychopathological structure of protracted endogenous depressions was studied. An attempt was made to eliminate the main components of the depressive syndrome (variants of the depressive affect - anguish, anxiety, apathy, ideator and motor inhibition and "supplementary" symptoms). The results of the study demonstrated some general psychopathological regularities in the interrelationship of components of the depressive triade and some nozological differences. The assumption is made of the heterogenity in the mechanisms of "delayed" depressions. The most significant appeared to be such factors as the character of the main affect, the degree of intensity and concord of the triade elements and the existence of "supplementary" psychopathological phenomens.

[Interhemispheric asymmetry according to evoked potential parameters in patients with depression].

In depressive patients with different degrees of severity of the disorder hemispheric differences of the occipital and central EP peak amplitude and latency were estimated under the conditions of presentation of a neutral light stimulus, structural stimulus, and mental reproducing the structural stimulus during presentation of the neutral one. Affective responses to the stimuli were also taken into account. In non-psychotic depression hemispheric asymmetry was observed in all responses studied being correlated with the dominant affect. In anxiety most of the EP components were higher in the right hemisphere; in sad affect they were higher in the left hemisphere. In psychotic depression, irrespective of the dominant affect, EP characteristics were higher in the right hemisphere.
