Relationship of headaches to depression.
One hundred and sixteen patients with major depressive disorder were asked for details of headaches during a depressive episode and during a nondepressed period. They experienced a headache rate similar to controls during the nondepressed period, but had an increased headache rate during depression (P less than .02). Patients with an increase in depressive headaches were younger, had more somatic complaints, and experienced more hypersomnia than other depressives.
