- This review investigates the relation between obstructive sleep apnoea and sleep apnoea headache, migraine and tension-type headache. Focus is made on studies from the general population with interviews conducted by a physician and obstructive sleep apnoea confirmed by polysomnography. Obstructive sleep apnoea syndrome is observed in 3% of the middle-aged population. The prevalence of sleep apnoea headache in this population is 12%-18%, while morning headache with similar symptomatology as sleep apnoea headache occur in 5%-8% of the general population. People with sleep apnoea headache did have significantly more minutes below 90% oxygen saturation (23.1 min vs. 1.9 min, p = 0.002), higher level of average oxygen desaturation (5.9% vs. 4.5%, p < 0.001) and lower average of the lowest oxygen saturation (80.9% vs. 88.5%, p < 0.001) than people with morning headache. A comparison of those with obstructive sleep apnoea with or without sleep apnoea headache showed no significant differences. Thus, oxygen desaturation alone cannot explain the pathophysiology of sleep apnoea headache. Obstructive sleep apnoea and migraine, and obstructive sleep apnoea and tension-type headache are not related in the general population. The cause of sleep apnoea headache remains to be elucidated.
