A case of cycloid psychotic disorder

Abstract

Based on a case of an acute and transient psychotic disorder with full recovery between recurrences, the authors remind the concept of cycloid psychoses. This diagnosis has been neglected in modern psychiatry and in the current nosological systems. However, the cycloid psychoses concept may offer an alternative diagnosis for some psychotic disorders in spite of the need of more studies to improve the understanding of its etiology and treatment.Ferreira MC et al. / Arch Clin Psychiatry. 2015;42(3):79-80
