Migraine with Aura Management in Stroke Survivors
Acute Migraine Treatment
- The American College of Neurology recommends using NSAIDs (ibuprofen, naproxen) or acetaminophen for acute headache management in patients with migraine with aura and a history of stroke 1
- Consider antiemetics (metoclopramide, prochlorperazine) for nausea without vascular risk in patients with migraine with aura and a history of stroke 1
- Employ non-pharmacologic measures including dark room, cold compress, and rest for acute migraine management in patients with migraine with aura and a history of stroke 1
Prophylactic Therapy
- The American Academy of Neurology recommends initiating migraine prophylaxis with propranolol 80-160 mg daily or topiramate 50-100 mg daily to reduce attack frequency and future stroke risk in patients with migraine with aura and a history of stroke 1, 2
- Propranolol has a dual benefit of migraine prevention and cardiovascular protection in patients with migraine with aura and a history of stroke 1, 2
- Topiramate is effective for reducing aura frequency in patients with migraine with aura and a history of stroke 1, 2
Secondary Stroke Prevention
- The American Heart Association recommends ensuring the patient is on antiplatelet therapy (typically aspirin or clopidogrel) as standard secondary stroke prevention in patients with migraine with aura and a history of stroke 1
- Low-dose aspirin serves a dual purpose for stroke prevention and may provide additional benefit given the migraine-related lesion burden in patients with migraine with aura and a history of stroke 1
Vascular Risk Factor Elimination
- The American College of Cardiology recommends smoking cessation as absolutely mandatory in patients with migraine with aura and a history of stroke, as smoking combined with migraine with aura creates catastrophic stroke risk (RR 9.03; 95% CI 4.22-19.34) 1, 2, 3
- Estrogen-containing contraceptives are absolutely contraindicated in women with migraine with aura, as they increase stroke risk 7-fold (RR 7.02; 95% CI 1.51-32.68) 1, 2, 3
- Aggressively manage hypertension, diabetes, and hyperlipidemia in patients with migraine with aura and a history of stroke 2
- Screen for hypercoagulable states, as migraine with aura associates with thrombophilia (OR 6.81; 95% CI 1.01-45.79) in patients with migraine with aura and a history of stroke 1
Monitoring and Follow-Up
- Monitor for any change in aura characteristics - new or prolonged symptoms (>60 minutes) require immediate stroke evaluation in patients with migraine with aura and a history of stroke 4
- Track migraine frequency monthly to assess prophylaxis effectiveness in patients with migraine with aura and a history of stroke 2
- Any objective neurological deficit persisting beyond typical aura duration warrants urgent imaging in patients with migraine with aura and a history of stroke 4
Neuroimaging Considerations
- Patients with migraine with aura and prior stroke have elevated risk of accumulating additional infarct-like lesions (OR 1.4; 95% CI 1.1-1.8) 1, 3
- Consider baseline MRI to document lesion burden, particularly cerebellar lesions which are common in women with migraine with aura (OR 1.9; 95% CI 1.4-2.6) 1, 3
