Sporadic Hemiplegic Migraine Presenting ATP1A2 Mutation in Korea

Hemiplegic migraine (HM) is a rare form of migraine, characterized by migraine with reversible motor weakness. HM can be divided into sporadic and familiar HM based on familiarity. Mutations in CACNA1A, ATP1A2 and SCN1A were identified in familiar HM. We present a patient with sporadic HM exhibiting recurrent hemiplegia, mental change and fever along with headache attacks. During the hemiplegia, he showed perfusion delay in left middle cerebral artery territory. Genetic panel test revealed a likely pathogenic varia nt in ATP1A2.
