Moyamoya Disease Definition in Chinese Explained
Moyamoya Disease Definition in Chinese Explained Moyamoya disease is a rare and serious cerebrovascular disorder. It affects the blood vessels in the brain. The name “moyamoya” comes from Japanese. It means a hazy network of tiny vessels that form when big arteries get blocked.
This network looks like a “puff of smoke” on scans. It happens because big brain arteries get narrower.
It’s important to understand Moyamoya disease in Chinese for Chinese speakers and those helping them. We use trusted sources like the National Institute of Neurological Disorders and Stroke. Also, the American Stroke Association and the Journal of Stroke and Cerebrovascular Diseases.
This helps us explain Moyamoya disease in Chinese. We want to make it clear for Chinese-speaking people. This way, we help them understand this complex brain disorder better.
Introduction to Moyamoya Disease
Moyamoya disease is a serious condition that affects blood flow to the brain. It happens when the main arteries to the brain get too narrow. This can lead to strokes, which are very dangerous.
What is Moyamoya Disease?
This disease is named “moyamoya” because it looks like smoke in the brain’s blood vessels. These vessels get tangled and try to make more blood flow. But, they’re not strong enough and can cause strokes.
Historical Background
In the 1960s, doctors in Japan first found moyamoya disease. They named it because of the “smoke-like” blood vessels. Now, it’s known worldwide, especially in East Asia. Research has helped us understand and treat it better.
Knowing about moyamoya disease helps doctors and patients deal with it.
| Aspect | Details |
|---|---|
| Origin | Japan, 1960s |
| Prevalence | Higher in East Asian populations |
| Major Risks | Ischemic and hemorrhagic strokes |
| Key Features | Narrowing of cerebral arteries, “puff of smoke” appearance |
Symptoms of Moyamoya Disease
Moyamoya disease shows many symptoms that change how people live. A common first sign is a transient ischemic attack (TIA), or a “mini-stroke.” This is when blood flow to the brain stops for a short time, causing brief brain symptoms.
Strokes are more serious and last longer than TIAs. Neurological symptoms like weakness on one side, vision problems, and trouble speaking can happen. Seizures are also a sign, caused by poor blood flow to the brain.
People with moyamoya may have trouble thinking clearly. They might find it hard to concentrate, forget things, or have trouble learning new things. Kids might not develop as they should.
Other signs include headaches and shaking movements. These can make the condition even harder to manage. Early diagnosis and ongoing checks are key for those with moyamoya disease.

Causes of Moyamoya Disease
Doctors are still studying moyamoya disease to find out why it happens. They know some things that make it more likely. Things like genes and the environment play big roles.
Genetic Factors
Scientists found some genes linked to moyamoya disease. These genes make it more likely to get the disease. For example, a gene called RNF213 is often found in people from East Asia who have moyamoya.
This gene affects the blood vessels in a way that can lead to moyamoya disease.
Environmental Factors
Things around us also affect moyamoya disease. Being exposed to radiation near the head is a risk. Some health conditions, like Down syndrome or sickle cell disease, also raise the risk.
How genes and the environment work together makes moyamoya disease complex.
| Factor | Details |
|---|---|
| Genetic Predisposition | Increased risk due to gene mutations (e.g., RNF213) |
| Radiation Exposure | Exposure to head radiation can increase risks |
| Medical Conditions | Conditions like Down syndrome and sickle cell disease |
Diagnosing Moyamoya Disease
Getting a correct moyamoya disease diagnosis is very important. It helps in starting treatment quickly and right. Doctors use both clinical checks and tests to spot the disease. They look for special blood vessel patterns in the brain.
Diagnostic Tests
Doctors use different tests to make sure they get the diagnosis right. First, they do a detailed check-up. Then, they use tests to see the blood vessels clearly.
- Magnetic Resonance Imaging (MRI): This scan shows the brain’s blood vessels and finds problems.
- Magnetic Resonance Angiography (MRA): It focuses on the blood vessels, showing the brain’s vascular structure.
- Conventional Angiography: This test is more invasive but shows blood flow in the brain clearly, helping spot moyamoya.
Medical Imaging Techniques
| Imaging Technique | Purpose |
|---|---|
| MRI | To get detailed brain images and find signs of damage. |
| MRA | To see blood vessels and find moyamoya disease signs. |
| Conventional Angiography | To show detailed blood vessel info and confirm moyamoya. |
| Cerebral Angiogram | To give clear images of brain blood vessels, key for moyamoya diagnosis. |
It’s crucial to use these tests and imaging to correctly diagnose moyamoya. This helps in managing and treating the disease well.
Moyamoya Disease in Chinese
Understanding moyamoya disease in Chinese-speaking areas is important. It looks at how common it is, awareness efforts, and the challenges patients and doctors face. The Chinese Journal of Stroke says it’s more common in East Asians. This means we need to focus on cerebrovascular disease awareness.
In China, getting better at diagnosing and treating moyamoya disease is happening. But, there are still big challenges. Culture and language affect how people get and share information. Making resources for the Chinese-speaking community can help spread the word better.

Treatment Options for Moyamoya Disease
Moyamoya disease is a rare condition that affects blood flow in the brain. Doctors use different treatments to help improve blood flow and prevent strokes. These treatments include surgery and medicine, each with its own benefits and risks.
Surgical Treatments
Surgery is a key way to treat moyamoya disease. It helps make sure blood gets to the brain properly. There are two main surgeries used:
- Direct Revascularization: This surgery connects a blood vessel on the scalp to a brain artery. A common type is the STA-MCA bypass, where the superficial temporal artery (STA) is connected to the middle cerebral artery (MCA).
- Indirect Revascularization: This method includes EDAS (encephaloduroarteriosynangiosis) and EMS (encephalomyosynangiosis). These help grow new blood vessels over time.
| Treatment Method | Procedure | Expected Outcome | Risks |
|---|---|---|---|
| Direct Revascularization | STA-MCA bypass | Immediate blood flow improvement | Infection, hemorrhage |
| Indirect Revascularization | EDAS, EMS | Gradual blood flow improvement | Delayed vascularization |
Medical Management
Moyamoya Disease Definition in Chinese Explained Along with surgery, doctors also use medicine to treat moyamoya disease. This approach helps manage symptoms and prevent strokes. Doctors may prescribe:
- Antiplatelet agents: These drugs help stop blood clots.
- Antihypertensive drugs: These lower blood pressure to reduce stroke risk.
- Anticonvulsants: These are for patients who have seizures.
Even though medicine alone can’t stop the disease from getting worse, it’s a key part of treatment. It’s especially important for people who can’t have surgery right away.
