Key clinical point: At the onset of attack, many patients with migraine with aura (MwA) experience stroke-like symptoms, whereas many patients with acute ischemic stroke (AIS) experience migraine-like symptoms, highlighting the need for additional clinical investigation for careful differential diagnosis.
Major finding: Migraine-like irritative sensations were experienced by 32.1% and 35.2% of patients with stroke who experienced visual disturbances and sensory disturbances, respectively, whereas stroke-like symptoms were reported by 12.0% and 31.4% of patients with MwA who experienced visual disturbances and sensory disturbances, respectively.
Study details: Findings are from a questionnaire-based observational study including 343 patients with MwA and 350 patients with AIS.
Disclosures: This study was supported by Swiss Heart Foundation. Several authors reported receiving research support, grants, personal fees, speaker fees, consulting or advisory support from Swiss Heart Foundation or other sources.
