Changes in Migraine Symptoms after Ischemic Stroke: A Cohort Study.

Introduction: Migraine symptoms are postulated to improve post-stroke. We aimed to determine post-stroke changes in patients with active migraine pre-stroke and explored the relation with stroke location and stroke-preventive medication use.

Methods: Patients with active migraine who had an ischemic stroke were retrieved from three research-cohorts between 2014 and 2021.
