Migraine, particularly migraine with aura, is a rare risk factor for ischemic stroke, especially in young women. Further research is needed to understand this association and other vascular risk factors.

Area of Science:

  • Neurology
  • Vascular Neurology
  • Epidemiology

Background:

  • Migraine is a common neurological disorder.
  • While often considered benign, emerging evidence suggests a potential link between migraine and ischemic stroke.
  • This association appears specific to certain patient subgroups, including young women with migraine with aura, particularly those who smoke or use oral contraceptives.

Observation:

  • This case series describes 6 patients diagnosed with migrainous stroke according to International Headache Society criteria.
  • The majority of patients were young women (5 out of 6), with a median age of 29.
  • All patients had migraine with aura; some used oral contraceptives and/or smoked, while others had no traditional vascular risk factors.

Findings:

  • All patients presented with ischemic stroke, confirmed by neuroimaging (MRI), affecting various cerebral arteries.

  • Common stroke manifestations included visual field defects (hemianopia, quadrantopia) and sensory symptoms.
  • Extensive laboratory and imaging tests ruled out common causes of stroke and thromboembolism.

    • Implications:

    • The findings support the hypothesis that migrainous stroke is more prevalent in young women with migraine with aura.
    • Given the high prevalence of migraine, further research is crucial to determine if migraine is an independent risk factor for stroke.
    • Understanding the pathogenetic mechanisms is essential for targeted prevention strategies in at-risk migraine populations.
