Bipolar<unk>  Disorder is a bipolar spectrum disorder that is characterized by at least one hypomanic episode and at least one major depressive episode; with this disorder, depressive episodes are more frequent and more intense than manic episodes.  It is believed to be underdiagnosed because hypomanic behavior often presents as high-functioning.[citation needed]
