Objective.—To find out whether there is a relationship between the headache characteristics and polysomnographic findings in patients with prediagnosis of the sleep apnea syndrome (SAS) and, if there is, to search for its possible cause.

Background.—Chronic morning headache is considered by many to be an important part of the SAS. Some reports support this relationship, and some do not.

Methods.—We questioned 75 patients with SAS about headache. Headaches were classified according to the International Headache Society (IHS-88) system. We evaluated the relationship between headache and polysomnographic findings.

Results.—There was no statistically significant relationship between headache and apnea hypopnea index (AHI) or minimal oxygen saturation (P > .05).

Conclusions.—We could not demonstrate a statistically significant relationship between headache, AHI, and minimal oxygen saturation in our patients with SAS.
