275 psychopathological observations of the affective disorders. The pr
imary symptomcomplexes of hypothymia and alienation are considered to

e ranged into the system with variants according to comorbid correlati
ons between hypothymia and alienation. The anesthetic depression (In w
hich the signs of vital affective supression and alienation are charac
terized by total symptomatological comorbidity) considered to form the
center of such system. The variations of affective disorders (vital,
existential, ''self-torture'' depressions, ''depression without depres
sion'') in which the comorbidity phenomenon is just partly realized an
d In which one of the symptomcomplex is totally expressed have the mar
ginal position.
