Hemiplegic Migraine is one of migraine subtypes. It is a rare disorder. If so, you should take verapamil or acetazolamide as the preventive medications. if they don't work well, you should try lamotrigine. If it still doesn't work well, you should try to take amitriptyline, topiramate , to valproic acid. Although data are scant and conflicting, we suggest not using beta blockers, triptans, and ergotamine derivatives to treat patients with hemiplegic migraine because of theoretical concerns and anecdotal evidence that these medications may lead to ischemia.
