Importance: Although sparse observational studies have suggested a link between migraine and cervical artery dissection (CEAD), any association between the 2 disorders is still unconfirmed. This lack of a definitive conclusion might have implications in understanding the pathogenesis of both conditions and the complex relationship between migraine and ischemic stroke (IS).
Objective: To investigate whether a history of migraine and its subtypes is associated with the occurrence of CEAD.
Background: Transesophageal echocardiography (TEE) has improved the diagnostic evaluation of ischemic stroke patients, permitting detection of potential cardiac sources of embolism. The present study aimed to evaluate the distribution of potential cardioembolic sources in young versus older stroke patients and their clinical implication for recurrent vascular events. Two hundred and twenty-eight patients with undetermined ischemic stroke were enrolled in the study.
