Moyamoya Disease: More Than Just a Word


If you’ve ever read a medical article and come across the word ‘Moyamoya,’ it probably made you think of that rare disease that causes blood vessels to swell in the brain then collapse.

However, Moyamoya disease doesn’t just refer to those experiencing such an unfortunate event. In this article, we cover more than just what one might expect from the name of this troublesome but interesting medical condition.

Have you ever heard of Moyamoya disease? If not, don’t worry – it’s not something that’s very common. Still, if you’ve been in the medical profession for a while, you might have heard of it before. It’s a neurological disease with a very specific set of symptoms. In this article, find out what it is and how to treat it!

Moyamoya is a word that has come into everyone’s vocabulary these days. It is an extremely uncommon disease that causes abnormal blood flow in the brain. What makes it more unique is that it has no known cure yet, and its only symptom is the appearance of a tunnel-like structure in the retina of one’s eyes.

What is Moyamoya Disease?

Moyamoya disease is a particular type of venous thrombosis that affects blood circulation in the brain. The name comes from the Japanese word “moyamoya,” which means “deformed mountain pass.” Patients with Moyamoya disease typically experience recurring hemorrhages, seizures, and other stroke-like symptoms. Moyamoya, a Japanese word for “big river in the woods” is a catch-all term for a group of diseases that have similar symptoms.

There are three types of Moyamoya Disease: aneurysmal subarachnoid hemorrhage, intracerebral hemorrhage, and cerebral infarction. All three result from a ruptured brain aneurysm and occur when blood accumulates around the artery walls. Moyamoya disease is a type of white matter disease. It’s called this because it affects the blood vessels in the brain, making them swell and eventually burst. This can cause permanent brain damage or even death.

Symptoms and diseases

Moyamoya disease is a type of stroke that occurs when an artery in the brain, the carotid artery, gets blocked. The disease is difficult to diagnose because it has no outward signs of problems and often has a slow onset. In adults, Moyamoya typically affects people over 45 years old. In children, Moyamoya typically occurs later in life. Moyamoya is a rare, progressive disease that starts in the arteries of the brain. The disease destroys the tissue in the cerebrovasculature, causing narrowing of blood supply to various areas around the brain.

A sufferer of Moyamoya may experience stroke-like symptoms along with inflammation in the brain or in other parts of their body. Moyamoya disease is caused by an artery that gets clogged. When the blood is not drained properly, it meets up with oxygen-poor blood in the brain and causes brain damage. There are many symptoms of Moyamoya including headaches, visual changes, seizures, and death in some cases.

Risk factors and history

Moyamoya Disease is an auto-immune disease that affects the arteries in the lungs. It most commonly affects the right side of the heart, but it is also possible for it to affect both sides of the heart. Early symptoms include blood in sputum, coughing up blood, chest pain, weakness, and dizziness. This condition can be fatal if left untreated. Moyamoya disease is a rare condition which has been linked to smoking, but the number of people who have it is steadily increasing.

Moyamoya disease is a progressive narrowing of the arteries in a part of the brain known as the carotid sinuses. This gets progressively worse and can lead to stroke or death. Moyamoya disease is a condition that develops when gas bubbles inside blood vessels cause arteries and veins to narrow and constrict. This process occurs in the brain, where the arteries and veins close off and restrict blood flow to, or within, parts of the brain. These areas are often left with insufficient blood flow, oxygenation, or both. When this happens, brain cells can die due to lack of nourishment

What things to do to avoid this disease?

Moyamoya disease is a condition that causes vasospasms, which drastically narrow the blood vessels in the brain. This illness starts as a scar-like tissue growth on the walls of certain arteries and eventually obstructs the flow of blood entirely. If you want to be protected against this disease, drink plenty of water and eat healthy foods like vegetables and nuts. Moyamoya disease is a condition that causes the brain’s oxygen highway to be blocked.

This can happen either because something has been lodged in the blood vessels, or because a blood vessel narrows and clogs up. What causes it? It can be a result of a hemorrhage, a tumor, an infection, an inflammation, or a narrowing of the veins. Once you know what caused your moyamoya disease it will be easier to prevent it next time.

Moyamoya disease is a condition that causes narrowing of the major vessels of the brain. It can be broadly classified as an intracranial thrombosis with compression, inflammation, and oxidative damage affecting cerebral arteries. The symptoms are most commonly related to stroke; it has been caused by carotid artery stenosis, external carotid artery stenosis, and atherosclerosis.
