Psicosis cicloide como diagnóstico válido y específico. A propósito de un caso

Cycloid psychosis is a nosological entity characterized by an acute onset, a remitting course, a favorable outcome and a symptomatological polymorphism. Its origin dates back to 1928 and its consideration as an independent diagnosis is currently controversial, since there is a lack of solid scientific evidence to support it. However, this article defends its validity as a specific nosology, with implications regarding treatment and, consequently, prognosis. For this purpose, we present the clinical case of a 37-year-old woman, admitted for the first time to the psychiatric inpatient unit due to a psychotic episode, which will resolve within days and will repeat recurrently, remaining asymptomatic and without cognitive impairment between different episodes.
