[Doomsday delusions of religious content (apocalyptic version)]

To define psychopathological and phenomenological characteristics of the apocalyptic variant of end-world delusion with religious content (EWDRC) in schizophrenia, to identify features of clinical dynamics of delusional disorders and their interaction with delusional behavior of patients.

A total of 28 patients with schizophrenia (F20.01, F20.02 according to ICD-10) and EWDRC were examined. Clinical-psychopathological and follow-up methods were used.

The development of the end-world delusional ideas occurred in unstructured affective-delusional disorder with acute sensual delusion. Two types of EWDRC were differentiated: with predominance of perception delusion or picturesque delusion. These types differed by acuity and massiveness of psychotic symptomatology, the mono- or polythematic character of delusional disorders, affect type, as well as by the duration and intensity of the development of delusional stages, and in their phenomenological specifics.

Delusional ideas of the end of the world in schizophrenic patients develop in the structure of the syndrome of acute sensory delusions with a predominance of delusions of perception (type I) or visual-figurative delusions of the imagination (type II), which have different duration, degree of dominance and depth of psychopathological disorders.
