Key clinical point: Patients with migraine had an increased risk for vascular dementia (VaD), with the risk being significantly higher in those with chronic vs episodic migraine.
Major finding: Compared with individuals without migraine, patients with migraine had a 1.21-fold higher risk for VaD (adjusted hazard ratio [aHR] 1.21; 95% CI 1.17-1.25), with the cumulative incidence of migraine being significantly higher in patients with chronic vs episodic migraine (log-rank P < .001).
Study details: This 10-year retrospective population-based cohort study included 212,836 patients with migraine and 5,863,348 participants without migraine, of whom 3914 (1.8%) and 60,259 (1.0%), respectively, were diagnosed with VaD during the follow-up period.
