A number of psychiatric syndromes feature depressed mood as a main symptom. The [[mood disorder]]s are a group of disorders considered to be primary disturbances of mood. These include [[major depressive disorder]] (commonly called major depression or clinical depression) where a person has at least two weeks of depressed mood or a loss of interest or pleasure in nearly all activities; and [[dysthymia]], a state of chronic depressed mood, the symptoms of which do not meet the severity of a [[major depressive episode]]. Another mood disorder, [[bipolar disorder]], features one or more episodes of abnormally elevated mood, [[cognition]], and energy levels, but may also involve one or more episodes of depression.<ref>{{cite book | vauthors = Gabbard G |title=Treatment of Psychiatric Disorders |edition=3rd |volume=2 |publisher=American Psychiatric Publishing |location=Washington, DC |page=1296}}</ref> Individuals with bipolar depression are often misdiagnosed with unipolar depression.<ref>{{Cite web |last=Jackel |first=Donna |date=2024-01-24 |title=Bipolar Depression vs. Unipolar Depression |url=https://www.bphope.com/everything-you-ever-wanted-to-know-about-bipolar-depression/ |access-date=2024-07-20 |website=bpHope.com |language=en-US}}</ref> When the course of depressive episodes follows a seasonal pattern, the disorder (major depressive disorder, bipolar disorder, etc.) may be described as a [[seasonal affective disorder]].
