[Clinical features of schizophrenia manifesting itself as transitory psychoses].

The clinical features as well as prognosis of schizophrenia manifesting by acute transient psychoses at a mature age were studied in 80 patients. Two types of manifesting attacks were described: the first one developed as an affective delirious state with fantastic subject matter of delirious emotional experience and with clouded consciousness; the second one developed as an acute paranoid. The latent period characterized by contractive reactive lability preceded transient psychoses as the disease manifestation. Psychic disorders that followed depended on the reactive lability of the latent period. The clinical course was slow-progressive; the repeated "clishe"-like attacks developed transiently. External pathogenic effects influence on transient psychoses clinical course is discussed. The peculiar variants of schizophrenic psychosis developing as transient attacks, which appeared to be reactions by their mechanism but fhyft by their clinical matter, are also discussed.
