The document summarizes changes made to mood disorders in the DSM-5 from the DSM-IV-TR. Key changes include renaming "mixed episode" to "with mixed features" specifier, adding "other specified bipolar and related disorder" for people with histories of major depressive disorder and hypomania, including premenstrual dysphoric disorder which was previously listed as needing more study, and adding disruptive mood dysregulation disorder for children experiencing persistent irritability and behavioral dyscontrol to address overdiagnosis of bipolar disorder in kids. Dysthymic disorder is now classified under the umbrella of "persistent depressive disorder."
