In 20 controls and 47 patients with chronic tension-type headache (TTH), we investigated the exteroceptive suppression period (ES), selfrating depression scale, and a questionnaire regarding symptoms. Early (ES1) and late (ES2) exteroceptive suppressions were observed. The mean duration of ES2 was significantly reduced in chronic TTH when compared with controls. Although no statistical significance of ES2 duration was found in the various clinical parameters, patients with severe headache, and a high score of the self-rating depression scale showed a shortening tendency of E52 duration. The depressive trend of patients with TTH might be responsible for modifying the descending input to the brainstem and reducing ES. To date, there have been no reports concerning ES2 and the severity of headache and score of self-rating depression scale.
