Atypical depression in children and adolescents

Major depressive disorder (MDD) with atypical features has been described in adults. Furthermore, several studies have suggested that tricyclic antidepressants were less effective for MDD with atypical features than for MDD without atypical features. Thus, it may be important to determine whether atypical features are present in MDD. To date, only one study has examined the diagnosis of depression with atypical features in children and adolescents by using the DSM-IV criteria. Current knowledge suggests the DSM-IV criteria for depression with atypical features in children and adolescents may need to be reconsidered, as biological, hormonal, developmental, and psychological factors in this age group may be different from those of adults with atypical depression.
