[Certain patterns in the effect of premorbid backgrounds on the shape of reactive psychoses]

Clinico-statistical analyses of 696 cases with reactive psychoses established that the psychogenic syndromes developing on a pathological background are predilectively formed in a uniform or adjacent to the premorbid psychopathological register. The tendency found is interpreted as signs of general pathological regularities in a reactive type formation. The clinical expression of these regularities is accomplished through the probabilistic preformation by the premorbid pathological background of the depth and quality of a psychogenically changed consciousness of the patients. Affective and personality-catathymic mechanisms are taken as a model in discussing the construction of the clinical picture and pathokinesis of reactive psychoses.
