Depressive disorders are common in children and adolescents [1,2], impair psychosocial functioning, and are often accompanied by comorbid psychopathology [3,4]. Despite its detrimental effects, pediatric depression is often undertreated.

The epidemiology, clinical manifestations, assessment, and diagnosis of pediatric depression are reviewed here. Treatment of depression in youths is discussed separately. (See "Overview of prevention and treatment for pediatric depression" and "Pediatric unipolar depression and pharmacotherapy: General principles" and "Pediatric unipolar depression and pharmacotherapy: Choosing a medication" and "Pediatric unipolar depression: Psychotherapy".)

6 to 11 years – 1.4 percent
