title: [Psychopathology, typology and nosological evaluation of juvenile endogenous depressions: a clinical and follow-up study].
abstract: A complex clinical-psychopathological and follow-up study of 751 patients (the clinical group included 393 subjects; the follow-up group consisted of 358 patients) with endogenous juvenile depressions of nonpsychotic level showed that specificities of depressive conditions in patients of this age (16-25 years) and special features of their clinical manifestations were conditioned by the considerable contribution of pubertal psychobiological factors to their formation. These factors bring cognitive, overvalued, behavioral, and somatovegetative disorders, characteristic of adolescence, into the foreground. The above disorders do not only mask their depressive foundation but also complicate the correct interpretation of separate symptoms of the disease. The basic key features of juvenile depressions include polymorphism of the clinical picture, atypism and bluntness of a depressive triad with insignificant intensity of its thymic component and predominance of apatho-adynamic and dysphoric components. Five special typological varieties of depressions, characteristic only of adolescence, were revealed and studied as well as 3 varieties peculiar both to youths and patients of mature age. Correlations among the types of adolescent endogenous depressions, specificities of their course, and nosological position of the studied states were detected.
