What are the key symptoms of basilar artery migraine?

Basilar migraine: The most common symptoms of basilar-type migraine in order of decreasing frequency include vertigo (sensation of environment spinning around you), dysarthria (slurred speech), tinnitus (ringing in the ears), diplopia (double vision), bilateral visual symptoms, bilateral paresthesias (such as numbness or tingling), decreased level of consciousness, and hyperacusis (increased sensitivity to sound).

Varied: In about 25% of patients, vertigo, slurred speech, and diplopia imply altered brainstem function. Commonly in adolescent women but also in others, total blindness and sensorial clouding accompanied by vertigo, slurred speech, tinnitus and distal/perioral paresthesias followed by a confusional state. The symptoms usually persist for 30 m followed by a throbbing occipital headache.
