[Population patterns in the dynamics of episodes and remission in patients with endogenous psychoses].

Analyzing the data on 1770 patients with paroxysmal schizophrenia with a disease standing of 15 years and over, the authors established a statistically significant correlation between the clinical picture of remissions and attacks in the preceeding and the subsequent cycle of the disease. This correlation was expressed in the fact and from the second cycle to the third, the probability of the appearance of the same psychopathological disturbances was at least two times as that of the development of any other concrete disorders. The first three cycles of the disease were analyzed.
