Bipolar Disorders
To enhance the accuracy of diagnosis and facilitate earlier detec on in clinical se ngs, Criterion A for manic and hypomanic episodes now includes an emphasis on changes in ac vity and energy as well as mood. The DSM-IV diagnosis of bipolar I disorder, mixed episode, requiring that the individual simulta- neously meet full criteria for both mania and major depressive episode, has been removed. Instead, a new speci er, “with mixed features,” has been added that can be applied to episodes of mania or hy- pomania when depressive features are present, and to episodes of depression in the context of major depressive disorder or bipolar disorder when features of mania/hypomania are present.
