Symptoms Of Moyamoya Syndrome

Moyamoya syndrome is a rare disorder in which a person's carotid artery is narrowed or blocked over a period of time. This reduces the blood flow to the brain. At the base of the patient's brain, small blood vessels will open as they attempt to supply adequate blood to the brain. Unfortunately, the tiny blood vessel clusters won't be able to provide the required oxygen and blood, causing permanent or temporary brain injury. Since moyamoya disease is progressive, symptoms will often appear in small forms and worsen over time. It's very rare for moyamoya disease to appear in individuals who aren't of Asian descent, but it is possible.
