The cycloid psychosis has attracted much interest in the international literature of the past 50 years, but the number of scientific studies have greatly decreased over the past 15 years, possibly partly explained by the misconception that the diagnosis has been incorporated in current diagnostic classification systems.
Cykloid psykos har rönt mycket intresse i den internationella facklitteraturen de senaste 50 åren men antalet vetenskapliga studier har kraftigt minskat de senaste 15 åren vilket möjligen delvis kan förklaras av missuppfattningen att diagnosen införlivats i aktuella klassifikationssystem (DSM– ICD).
