The purpose of this study was to determine the prevalence of migraine headaches in patients with ischaemic stroke. In this prospective cohort study, we assessed 323 patients with ischaemic stroke; these diagnoses were assigned based on the International Headache Society criteria for migraine with or without aura. Patients were recruited without major risk factors such as stroke, hypertension, hyperlipidaemia, diabetes, taking oral contraceptive pills, history of drug abuse and trauma in issue of their Stroke. Data were collected via a written questionnaire upon admission and were analysed with SPSS version 16 software. Comparisons were performed using Mannâ€"Whitney's U test and chi-square and t-test. Migraine headache was present in 11.2% (36 of 323) of patients, 8.1% of women and 3.1% of men. Migraine prevalence was highest in the age over 60 years. There was a history of migraine without aura for over 2 years in 6.2% of patients with ischaemic stroke. Also, we found no significant correlation between migraine headache and location of the lesion in patients with ischaemic stroke.
