Migraine and stroke risk

Patients with a history of migraine have a heightened risk of perioperative ischaemic stroke, according to new research published in The BMJ. In a prospective hospital-based registry study, migraine was associated with a 1.75-fold increase in the incidence of stroke within 30 days of surgery, and the risk was particularly high in patients who had migraine with aura. In light of these findings, the authors propose that migraine should be included in perioperative risk assessment protocols.
