Outline of Final Research Achievements	Moyamoya disease is a chronic obstructive cerebrovascular disease with unknown cause. Pediatric cases usually manifest with brain ischemic symptoms. The purpose of the present study is to review long-term outcome of pediatric moyamoya disease after adulthood and elucidate characteristics of and effective intervention for neurocognitive dysfunction in pediatric moyamoya disease. Late-onset de novo hemorrhage and social adaptation difficulty are two major problems after pediatric patients reach adulthood. Social adaptation difficulty, related to neurocognitive impairment caused by infarct and chronic frontal ischemia, continues in 10-20% of patients. Pediatric patients with infarct had impairment of neurocognitive function including working memory, simultaneous and successive processes, and attention. Occupational therapy and neurosurgical intervention during childhood might be effective for preventing decreased quality of life in adulthood, subject to be verification in further studies.
