Moyamoya disease is a rare, progressive cerebrovascular disorder caused by blocked arteries at the base of the brain in an area called the basal ganglia. Moyamoya means “puff of smoke” in Japanese and is used to describe the tangled appearance of tiny vessels compensating for the blockage. In moyamoya disease, arteries to the brain become narrow and may even close, leading to reduced delivery of oxygen-rich blood to the brain.
This lack of blood flow to the brain can cause a stroke and other symptoms. Moyamoya disease is a rare condition that affects the blood vessels in your brain. It can lead to brain bleeds and stroke in affected areas of your brain. There’s no cure for moyamoya disease.
moyamoya brain disorder, Treatment typically involves managing symptoms and preventing blood clots with medications. Moyamoya is a rare vascular disease that affects the blood vessels in the brain. Over time, the main arteries that supply blood to the brain become narrowed or blocked. These include the carotid arteries, which run along both sides of the neck and carry oxygen-rich blood from the heart to the brain. Moyamoya disease is a rare disease in which a blockage to the carotid artery in your head reduces how much blood can get to your brain.
moyamoya brain disorder, Moyamoya syndrome is unilateral arterial constriction, or occurs when one of the several specified conditions is also present. [3] This may also be considered as moyamoya being secondary to the primary condition. Mainly, occlusion of the distal internal carotid artery occurs. Moyamoya is an uncommon cerebrovascular condition characterized by the progressive narrowing of large intracranial arteries around the circle of Willis and the secondary development of prominent small-vessel collaterals. Moyamoya disease is often diagnosed in children 10 to 14 years old, or in adults in their 40s. Females and people of Asian ethnicity have a higher risk of moyamoya disease, and research studies show a genetic link.
The term “moyamoya” is Japanese, and refers to a hazy puff of smoke or cloud.
