A nationally representative sample of 2695 people found that the 5.3% who experience migraines were significantly more likely to report poor sleep quality, reports Medscape.

Although the mechanism remains unclear, cortical spreading depression, hyperexcitability, and changes in the thalamo-trigeminal tract and/or the orexin pathway may explain the association between sleep and migraine, study investigator Tae-Jin Song, MD, PhD, from the Department of Neurology at the Ewha Womans University College of Medicine in Seoul, South Korea, said here at the American Headache Society (AHS) Annual Meeting 2018.

In addition to asking patients with migraine about sleep quality, Song recommended some proven interventions to reduce headache frequency and intensity in previous studies.
