Affective disorders--concept, classification, and location in ICD-10

In 1899, Kraepelin, E. proposed the concept of affective disorder as "Das manisch-melancholische Irressin". The classification of MDI had changed in several years. WHO developed the ICD-10 in 1990. In the F3 category of ICD-10, it is stated that MDI is a "mood (affective) disorder". In that category, there are seven categories which are divided in to several subclasses. The episodic mood disorders are "manic episode", "bipolar affective disorder", "depressive episode" and "recurrent depressive disorder". In contrast to these groups, the persistent mood disorders are "dysthymia" and "cyclothymia". In addition, there are two other items, "organic mood disorder" (F06.3) and "mixed anxiety and depressive disorders" (F41.2).
