[Latent endogenous depressions in adolescents].

A clinico-catamnestical study of 200 adolescents with depressive conditions in endogenous psychoses revealed 28 patients who suffered from schizophrenia and manic-depressive psychosis with manifestations of larvate depressions. It was established that larvate depressions in adolescents in the majority of the cases proceed with disorders of behaviour and poor school progress. The clinical picture is characterized by diverse somatic complaints in the absence of actual somatical pathology. Larvate depressions in adolescents differ significantly from similar states in adults, inasmuch as poor progress in school is due to disorders of cognitive activity during the disease.
