Basilar artery migraine 12 patients, with an attack recorded electroencephalographically.

Basilar artery migraine is distinctive disorder characterized by symptoms referable to dysfunction of brainstem structures in conjunction with more typical migrainous phenomena. Our experience with 12 cases, seen in a period of 10 years, is reviewed. In one instance, an attack of basilar artery migraine was captured by EEG, and appeared as a typical photoconvulsive response. More than half of our patients responded well to anticonvulsant drugs.
