Comorbid depressive and anxiety disorders are commonly seen in both primary care and the specialty setting. Such comorbidity can present as major depression with subsyndromal anxiety symptoms or unipolar/bipolar depression with an anxiety disorder.

Although depressive and anxiety disorders are classified as distinct groups of illnesses, studies document their frequent co-occurrence and provide evidence of a common biological substrate and a shared vulnerability.
