May 11, 2015: Basilar-type migraine
May 11, 2015
Migraine headache is a common primary headache syndrome, affecting upwards of 12% of the population. Basilar-type migraine, or migraine with brainstem aura, is felt to be a subset of typical migraine with aura. Theories speculate that the aura associated with this type of migraine is secondary to cortical spreading, affecting the brainstem or bilateral cerebral hemispheres. Bickerstaff initially termed this basilar artery migraine, although no clear association or vasculopathy of the basilar artery has been proven to date. Typical symptoms include brainstem findings of dysarthria, vertigo, tinnitus, hypacusis, diplopia, ataxia, or diminished consciousness, with vertigo and dysarthria being most common. Diagnosis can be difficulty given the similarity to stroke, TIA and posterior fossa disease. MRI and MRA imaging should be used to exclude a vascular lesion or brainstem pathology.
