Affective disorders-developments of ICD-11 in comparison with ICD-10

With the introduction of the 11th revision of the World Health Organization (WHO) "International Statistical Classification of Diseases and Related Health Problems" (ICD-11), structural and content-related adjustments were made to the diagnostic guidelines for affective disorders, which are presented in this review article. The update has resulted in some changes to the diagnostic classification of affective disorders, based on the American Diagnostic and Statistical Manual of Mental Disorders 5 (DSM-5). The ICD-11 assigns depressive symptoms to so-called clusters, the main symptoms of depressed mood and joylessness can be accompanied by cognitive, behavioral or neurovegetative symptoms. In the case of remission of depressive episodes, the ICD-11 distinguishes between partial and complete remission. A persistent depressive disorder is present if the depressive episode lasts continuously for more than 2 years. In future, bipolar disorder will be divided into type I and type II. Manic episodes can still only be coded in the context of bipolar disorders and cannot be diagnosed as an independent, separate disorder. The concept of persistent affective disorders in the ICD-10 is abandoned, dysthymia is categorized as a depressive disorder and cyclothymia as a bipolar disorder.
