Key clinical point: Patients with benign paroxysmal positional vertigo (BPPV) are at a higher risk for migraine diagnosis, with female sex, hyperlipidemia, and anxiety being significant risk factors for migraine among patients with BPPV.
Major finding: In 11 years of follow-up, 1.35% vs 0.41% of participants with vs without BPPV had migraine, respectively. The risk for migraine was 2.96-fold higher among those with BPPV (adjusted hazard ratio [aHR] 2.96; 95% CI 2.30-3.80; P < .001) and significantly higher among women (aHR 2.91; 95% CI 2.30-3.80), those with hyperlipidemia (aHR 1.77; 95% CI 1.16-2.70), and those with anxiety (aHR 1.49; 95% CI 1.03-2.14).
Study details: Findings are from a retrospective cohort study including 1386 patients with BPPV and 5544 age- and sex-matched control individuals without a history of BPPV or migraine.
