According to a recent study published in the Journal of Headache and Pain, Insomnia shows a significant association with migraine and non-migraine headaches. Insomnia is a problem in falling or staying asleep which affects approximately 10 to 30 % of the population. Insomnia and migraine displays a strong association as many of the studies demonstrated notable comorbidity for these two disorders in population-based and clinical studies. This study involved the investigation of the influence of migraine on the clinical presentation of insomnia signs using information from the Korean Headache-Sleep Study (KHSS).

The subjects who showed  ≥ 10 Insomnia Severity Index (ISI) score was known to suffer from insomnia. Total and subcomponent scores of the ISI were used to evaluate the clinical presentation of insomnia indications.

Out of 2695 patients, 290 and 143 individuals suffered from insomnia and migraine respectively. The subjects with insomnia shows higher incidences of non-migraine and migraine headaches than subjects without insomnia. Also, the total ISI scores of the individuals with insomnia did not vary among participants with non-headache, non-migraine, and migraine. Greater ISI scores for noticeability of sleep problems to others were reported among patients with non-migraine and migraine headache than those without headache. Other ISI subcomponent scores showed no variations between headache status groups. Moreover, no significant association was seen between insomnia severity and headache status among the insomnia subjects. All these findings highlight a substantial impact of migraine on insomnia.
