[Paranoid disorders in the debut and further course of late schizophrenia].

A study of 60 schizophrenic patients permitted to clinically analyze the state of late paranoic psychoses, which is difficult for differential diagnosis due to pronounced age syndromological atypicity. The allocation of these prevalently slowly progressive forms to late schizophrenia is based on studies of the regularity of the disease, particular clinico-psychopathological traits of the paranoic syndrome as well as on the hereditary loading data, premorbid traits and signs of mental abnormality in the past. The data obtained indicate a relationship between pronounced age atypicity of the psychoses and the degree of progression of the schizophrenic process.
