Summary
Migrainous cerebral infarction, a rare stroke type in migraine with aura patients, often results in mild symptoms and good recovery. Post-stroke, patients experienced reduced headache frequency and severity.
Area of Science:
- Neurology
- Cerebrovascular Diseases
- Headache Disorders
Background:
- Migrainous cerebral infarction is a rare complication of migraine with aura.
- Identifying and understanding its characteristics is crucial for patient management.
Purpose of the Study:
- To describe the clinical presentation and outcomes of patients with migrainous cerebral infarction.
- To investigate potential mechanisms for migraine improvement post-stroke.
Main Methods:
- Observation of six patients meeting strict criteria for migrainous cerebral infarction.
- Exclusion of other potential causes of stroke.
- Longitudinal assessment of migraine history, stroke severity, recovery, and recurrence.
Main Results:
- All patients had a history of migraine with aura.
- Most strokes were mild with good recovery and no recurrence.
- Headache frequency and severity decreased following the stroke.
Conclusions:
- Migrainous cerebral infarction can be a mild event with favorable outcomes.
- Reduced headache symptoms post-stroke may be linked to altered cerebral blood vessel reactivity and nociceptive transmission.
