Migraine is a frequent characteristic of acute ischemic stroke (IS) in younger patients but infrequent in older individuals. These patients are predominantly women, with stroke features varying by age.

Area of Science:

  • Neurology
  • Stroke Medicine
  • Epidemiology

Background:

  • Acute ischemic stroke (IS) is a significant cause of morbidity and mortality.
  • The association between migraine and IS, particularly in active migraineurs, requires further characterization.
  • Understanding demographic and clinical features of IS in patients with migraine can inform prevention and treatment strategies.

Purpose of the Study:

  • To investigate the specific characteristics of acute ischemic stroke (IS) in patients experiencing active migraine.
  • To compare IS patients with active migraine across different age groups (under 45 and 45+) and with age-matched controls without migraine.

Main Methods:

  • Prospective analysis of patients within a population-based primary care stroke registry.
  • Diagnosis of prior migraine based on International Headache Society criteria.

  • Univariate and multivariate analyses comparing IS patients with and without migraine, stratified by age.

    • Main Results:

    • 3.7% of 3,502 IS patients had active migraine, with higher prevalence in younger individuals (15.8%) than older (2.1%).
    • Women comprised a significantly higher proportion of IS patients with migraine (74% younger, 63% older).
    • Younger migraineurs showed characteristic posterior circulation involvement and patent foramen ovale; older migraineurs surprisingly lacked typical vascular risk factors.

    Conclusions:

    • Migraine is a notable feature in younger IS patients but less common in older IS patients.
    • Ischemic stroke patients with migraine are predominantly female, exhibiting age-specific stroke characteristics.
    • The findings highlight distinct patterns of IS in migraineurs, emphasizing age-dependent differences.
