Although there are several hypotheses about the biologic link between migraine with aura and ischemic stroke, the precise mechanisms remain unclear. However, because the absolute risk of stroke is low in patients with migraine with aura, and migraine without aura is likely not associated with ischemic stroke, most migraine patients will not experience a stroke event.Kurth T, Diener HC. [https://pubmed.ncbi.nlm.nih.gov/18778576/ Current views of the risk of stroke for migraine with and migraine without aura. Current pain and headache reports.] 2006 Jun 1;10(3):214-20. *According to large series, migrainous infarct accounts for 0.5-1.5% of all ischaemic [[stroke]]s and 10-14% in young patients. Migraine itself might cause spasm or even hyperplasia. It is unlikely to be the cause of embolism or among other disorders. dissection. Migrainous infarct due to severe hypoperfusion during an attack is rare and mostly involves the posterior-cerebral-artery territory and is more common during attacks of migraine with aura than without aura. The precise mechanism of this severe hypoperfusion is unknown. Increased risk due to treatments used in migraine, particularly vasoconstrictors, is supported by the increase in white-matter abnormalities and in mortality found in patients taking ergotamine, but two recent studies found no increase in severe vascular events with triptans. Drugs widely used in migraine, such as aspirin and non-steroidal anti-inflammatory drugs, decrease the risk of cerebral ischaemic events.Bousser MG, Welch KM. [https://pubmed.ncbi.nlm.nih.gov/16109360/ Relation between migraine and stroke.] The Lancet Neurology. 2005 Sep 1;4(9):533-42. *Migraine headache can occur as a comorbidity of ischaemic [[stroke]], carotid or [[Vertebral Artery|vertebral artery]] dissection, arteriovenous malformations, cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL syndrome), or platelet disorders (eg, thrombocytosis).Dalkara T, Nozari A, Moskowitz MA.
