Course and prognosis of endogenous-phasic psychoses in adolescence

The course and the prognosis of endogenous-phasic psychoses in adolescence were discussed on authentic cases with a long enough period of observation. In atypical psychosis, the length of episodes was longer when productive symptoms were present, while the defect symptoms were quite scarce when affective features dominated the episodes. In contrast to adult cases, myth formation was not recognized, while the tendency to repeat the same clinical picture was not consistent. In affective psychosis, the precipitating factors were significantly frequent in the initial episodes. The length of episodes tended to become longer along with the increase in age, but fairly long-lasting remissions were observed in a few patients.
