Key clinical point: Patients with migraine experiencing typically left-sided headache during attacks had a higher burden of headache frequency and severity than those experiencing typically right-sided headache.
Major finding: Patients with left-sided vs right-sided migraine had 3.5 (95% CI 0.6-6.4) fewer headache-free days and 3.3 (95% CI 1.3-5.4) more severe headache days per 4 weeks. There were no other significant differences in migraine characteristics or psychiatric comorbidities between patients with left- and right-sided migraine.
Study details: This cross-sectional study included 340 patients with migraine, of whom 166 (48.8%) and 174 (51.2%) had left- and right-sided migraines, respectively.
Disclosures: The study did not disclose any funding source. The authors declared no conflicts of interest.
