Persistent depressive disorder, also called dysthymia, is a form of chronic depression, with symptoms less severe but longer lasting than other forms of depression. It is a new diagnosis that combines two earlier diagnoses: dysthymia and chronic major depressive episode. Since symptoms are less acute than major depressive disorder, it may go unnoticed for some time.


Treatment of Persistent Depressive Disorder and Prognosis

Treatment for persistent depressive disorder include medications and psychotherapy. A combination of the two is believed to be the most effective treatment. Psychotherapy includes cognitive behavioral therapy and interpersonal therapy. Medications include selective serotonin reuptake inhibitors (SSRIs), serotonin and norepinephrine reuptake inhibitors (SNRIs) and tricyclic antidepressants (TCAs).
