"Cyclothymia (pronounced /ˌsaɪkləˈθaɪmiə, ˌsɪklə-/) is a mood disorder and a form of bipolar disorder. It is defined in the bipolar spectrum. Specifically, this disorder is a form of bipolar II disorder consisting of recurrent mood disturbances between hypomania and dysthymic mood. A single episode of hypomania is sufficient to diagnose cyclothymic disorder; however, most individuals also have dysthymic periods. The diagnosis of cyclothymic disorder is never made when there is a history of mania or major depressive episode or mixed episode. The lifetime prevalence of cyclothymic disorder is 0.4-1%. The rate appears equal in men or women, though women more often seek treatment."
