BACKGROUND Hemiplegic migraine (HM) is a rare type of migraine with aura. Some reports have described the clinical manifestations in HM patients with the ATP1A2 mutation. But the impact of the ATP1A2 mutation on cognitive profile in HM patients has not been evaluated in detail. Here we report a patient with cognitive dysfunction in specific area. CASE PRESENTATION A 15-year-old boy with an aura that included disturbances in consciousness, associated with fever, vomiting, hemiplegia, and aphasia. He was diagnosed with HM with the ATP1A2 mutation before. He had trouble in mathematics and depicting three-dimensional things. CONCLUSIONS The HM with ATP1A2 patient could develop permanent cognitive dysfunction. Therefore, the cognitive quotient should be carefully and comprehensively evaluated.
