Moyamoya Syndrome Risk Factors & Causes

Moyamoya syndrome is a rare progressive vascular disorder that involves the blocking or narrowing of the skull's carotid artery, which reduces blood flow to the brain. At the base of your brain, tiny blood vessels erupt to try to supply blood to the brain. The blood vessels aren't capable of providing necessary oxygen and blood to the brain, so the patient will suffer a brain injury, the severity of which will vary widely. There is no known root cause of Moyamoya syndrome, but certain characteristics increase the likelihood of developing the disease.
