[Clinical aspects and course of schizophrenia from the aspect of age]

Abstract

On the basis of a study of 3500 schizophrenic patients the authors studied the age preference of 8 schizophrenic syndromes selected for this purpose. It was demonstrated that besides some syndromes typical of schizophrenia occurring in middle age (hallucinatory-paranoid, oneiroid, etc.) there are some syndromes which are most frequently encountered in adolescency and old age. It was also shown that the influence of age factors can be combined with the influence of sex. The age factors exert a certain impact on the formation of the type of disease and its sex distribution. The paper contains a description of special age forms of schizophrenia encountered in adolescency and in old age.
