Mixed Episode

The DSM-IV diagnosis of bipolar I disorder, mixed episode, requiring that the individual simultaneously meet full criteria for both mania and major depressive episode, has been removed from the DSM-5.

Instead, a new specifier, “with mixed features,” has been added, according to the APA, that can be applied to episodes of mania or hypomania when depressive features are present. It can also be applied to episodes of depression — such as in the context of major depressive disorder or bipolar disorder — when features of mania/hypomania are present.
