Moyamoya disease is a chronic progressive obstructive disease of the cerebral blood vessels where abnormal microscopic blood vessels are observed at the base of the brain as the end of the arterial vessels in the brain narrow gradually for no specific reason and eventually become blocked. The term “moyamoya” means “puff of smoke” in Japanese, which describes the shape of small blood vessels formed to compensate for cerebrovascular blockages [Moyamoya disease has two age-at-onset patterns. A study by the Korea Health Insurance Review and Assessment Service showed that the age at first moyamoya disease diagnosis is generally in the 10–19-year range (pediatric group) for 21.6% of the patients and 50–59-year range for 30.0% (adult group) [The main clinical features of moyamoya disease are slightly different among children, adolescents, and adults. Hemorrhage is common in adults, while children and adolescents have recurrent transient ischemic attacks (TIA) [Factors that trigger clinical symptoms of moyamoya disease include situations that involve hyperventilation, such as singing, blowing on musical instruments, intense crying, excessive exercise, and eating hot or spicy food [
