[Comparative-age features of the dynamics of delusional syndromes in the course of paranoid schizophrenia].

The characteristics of the time-course of delirious syndromes in paranoid schizophrenia with the psychotic manifestation in juvenile (under 20 years) and elderly age (over 45 years) were studied. Patients with juvenile manifestations of psychosis (20 men and 11 women) exhibited the complexity and variability of delirious syndromes. At the same time, the stability and intensity of the manifestations of individual psychopathological phenomena attended with the homogeneity of the psychosis structure were noted. The absence of the phenomenological clarity of delirious emotions was associated with an unfavourable course of psychosis. In a group of patients with a late manifestation of psychosis (11 males, 57 females), the delirious syndromes were inert in nature. The phenomenological structure of the syndrome consisted of the reduced and chronic forms of delirious perception and delirious imagination with time, ideas of persecution assumed greater prominence in the content of psychosis.
