Key clinical point: Poor sleep could be a significant risk factor for an ensuing migraine attack, and an intensely painful migraine attack may lead to a subsequent increase in sleep duration, thus highlighting that sleep hygiene is an inherent part of migraine management.
Major finding: The odds of having a migraine attack increased by 6.1% and 17.4% with every deviation from mean sleep and every sleep interruption, respectively, during the previous day, whereas the overall sleep duration had no effect on attack occurrences. An intensely painful attack (M = 0.13; 95% high density interval 0.06-0.20) positively predicted increased sleep duration during the same evening.
Study details: This retrospective cross-sectional study included 724 patients (ages, 18 -81 years) with a mean monthly migraine attack frequency of 9.94.
