Migraine-associated stroke affects mostly women and may involve vasospasm. Imaging confirmed stroke in over half of patients, with arteriography showing abnormalities in some cases.

Area of Science:

  • Neurology
  • Vascular Neurology
  • Neuroimaging

Background:

  • Migraine is a common neurological disorder.
  • Migraine-associated stroke is a rare but serious complication.
  • Understanding the pathophysiology of migraine-associated stroke is crucial for diagnosis and treatment.

Observation:

  • A prospective study evaluated 22 patients with acute migraine-associated stroke.
  • The study group comprised 91% females, with 23% having a history of migrainous stroke.
  • Standard stroke risk factors and mitral valve prolapse were not more prevalent than in the general population.

Findings:

  • Brain imaging (CT, MRI, or radionuclide scan) detected ischemic or hemorrhagic infarction in 55% of patients.
  • Cerebral arteriography revealed stroke-related abnormalities in 42% of cases, with a higher incidence (67%) when performed within 72 hours of stroke onset.

  • Extracranial and/or intracranial vasospasm is implicated as a potential major factor in some cases of migrainous stroke.

    • Implications:

    • Migraine-associated stroke may result from various mechanisms, with vasospasm being a significant contributor.
    • Neuroimaging and cerebral arteriography are valuable diagnostic tools.
    • Further research is needed to elucidate the precise mechanisms and optimize management strategies for this condition.
