Key clinical point: Migraine diagnosis was not significantly correlated with a higher frequency of an absence of ischemic penumbra, its volume, or the prognosis of ischemic stroke.
Major finding: There was no significant association between migraine diagnosis and the absence of ischemic penumbra ( P = .649), stroke volume ( P = .995), or prognosis of ischemic stroke.
Study details: Findings are from a prospective cohort study including 221 patients with ischemic stroke who were hospitalized within 72 hours of the onset of symptoms, of which 59 had migraine.
Disclosures: The study was financed in part by the Coordenaçao de Aperfeiçoamento de Pessoal de Nível Superior-Brasil. The authors declared no conflicts of interest.
