A Study to Assess the Association Between Sleep and Migraine.

Introduction Migraines and sleep disturbances affect the majority of people globally. The underlying pathophysiological basis for the role of sleep disturbances in the causation of migraine remains poorly understood due to the complexity of brain functions. As studies assessing the association between sleep disorders and migraine are scarce, the present study was conducted. Materials and methods This study was conducted after obtaining approval from the Institutional Ethics Committee. A total of 60 patients with migraine and 60 age- and gender-matched controls were included after obtaining voluntary, written, and informed consent, provided they met the inclusion and exclusion criteria. Demographic details and relevant histories were noted. Severity of migraine and sleep disturbances was assessed by self-reported questionnaires. Results In the present study, it was noted that both groups were similar in terms of demographic details and personal histories. The global Pittsburgh sleep quality index (PSQI) was significantly higher in cases as compared to controls. Strong positive correlations were noted between global PSQI and numerical pain rating (NPR), headache impact test (HIT-6), and migraine disability assessment (MIDAS) scores. Conclusion Patients with migraine have poor sleep quality and disturbed sleep. The sleep quality also worsens with an increase in the severity of the migraine. Therefore, it is recommended that sleep quality should be evaluated in the initial assessment, and treatment should be instituted accordingly.
