A<unk> , formerly known as a<unk> -manic or<unk>  episode, has been defined as a<unk>  wherein features unique to both depression and mania—such as episodes of despair, doubt, anguish, rage or homicidal ideation, suicidal ideation, splitting, racing thoughts, sensory overload, pressure of activity, and heightened irritability—occur either simultaneously or in very short succession. Previously, the diagnostic criteria for both a manic and depressive episode had to be met in a consistent and sustained fashion, with symptoms enduring for at least a week (or any duration if psychiatric hospitalization was required), thereby restricting the official acknowledgement of<unk> s to only a minority of patients with bipolar I disorder. In current DSM-5 nomenclature, however, a<unk>  episode" no longer stands as an episode of illness unto itself; rather, the symptomology specifier "with<unk>  features" can be applied to any major<unk>  episode (manic, hypomanic, or depressive), meaning that they are now officially recognized in patients with, in addition to bipolar I disorder, bipolar II disorder and, by convention, major depressive disorder. A depressive<unk><unk>  in a patient, however, even in the absence of discrete periods of mania or hypomania,<unk> ly rules out unipolar depression.
