Basilar migraine is a special form of migraine. The episodes usually last minutes to hours and are accompanied by transient neurological deficits in the vertebrobasilar territory. The transient deficits include vertigo, gait ataxia, visual deficits, or dysarthria. The symptoms may occasionally be accompanied by nausea and vomiting. Approximately 80% of affected individuals have a positive family history of migraine. Basilar migraine occurs in children through adolescence1.
