Neurologic complications of migraine.

Migraine can be associated with hemiplegia, ophthalmoplegia, retinal and vertebrobasilar insufficiency, amnesia, confusion, altered perception, stupor and even death. Migrainous complications must be differentiated from structural lesions, metabolic disorders, convulsive states are cerebrovascular thromboembolism. Treatment of complicated migraine is directed toward prophylaxis of vasoconstriction. Agents that produce vasoconstriction, such as ergot preparations, and known migraine precipitants should be avoided in migraineurs.
