This paper outlines the diagnostic requirements and additional features of disorders included in ICD-11 Mood Disorders, while comparing them with those in ICD-10 and DSM-5. Mood disorders are diagnosed, as in DSM-5, with Depressive, Manic, Hypomanic and Mixed Episodes as their components. The division of Bipolar Disorders into Bipolar I and Bipolar II also follows the footsteps of DSM-5. On the other hand, the so-called mixed state is designated as the "with mixed features" specifier in DSM-5, while in ICD-11, it serves as an independent component of a Bipolar Disorder called "Mixed Episodes," with its diagnostic requirements set up relatively loosely. ICD-11 classification of mood disorders is well harmonized with that of DSM-5, and those who are familiar with DSM-5 will find it easy to use. However, there are a number of important changes in the details of the ICD-11, and it is necessary to understand how ICD-11 differs from ICD-10 and DSM-5.
