ABSTRACT

Migraine and depression are common conditions that often coexist. The combination of several mechanisms may explain this comorbidity. A number of studies showed consistent association between depression and primary headache disorders including migraine; however, migraine with aura showed the strongest association with depression. This review highlights the background of migraine and depression, and summarizes studies that have investigated the risk for depression in migraine sufferers.
