Psychopathology of depersonalisation depression

77 patients (29 men, 48 women) at the age of 17-51 years with depersonalisa tion depression (DD) of nonpsychotic level with duration 6 months and longe r. Such depressions were psychopathologically characterized by close connec tion between affective and depersonalisating components of the syndrome. Th e depressive component manifested with a mild hypothymia with dissociation between subjective severity and ojbectice self-estimation, vulnerability to provoking factors, inversion of somatic symptoms that permit to evaluate a ffective disorders as "atypic depression" (according to DSM-IV). Peculiarit ies of depersonalizating component were relatively low degree of the aliena tion phenomena and their psychopathic (hysteric) colour. Personal status of the patients before disease's manifestations was characterized by some sig ns of accentuation of a self-consciousness sphere and corresponded to borde rline disorders. The conclusion was made about the existence of a particula r type of DD in which symptomecomplexes, relatively independent (affective and depersonalisating), had a mutual affinity; so they united according to mechanism of pathologic synergism. This type of depression is only one of v ariants of DD.
