[The psychopathology of endogenous apathetic depressions].

The author examined 60 patients with manic-depressive psychosis and schizophrenia. In all cases the apathetic depression was observed in the psychopathological structure of these psychoses. On the basis of clinical analysis 3 types of apathetic depression were differentiated: simple apathetic (24 patients), apatho-melancholic (17 patients) and apatho-adynamic (19 patients) depression. The clinical picture of each of these types of apathetic depression was highly heterogeneous according to affective disturbances, different symptoms combinations and severity of disorder.
