Moyamoya disease is a rare condition that affects the brain. It happens when the main arteries in the neck get narrower. This makes a network of tiny blood vessels form, looking like “puff of smoke” on scans.
Definition and Characteristics
This disease makes the arteries leading to the brain get narrower on both sides. It leads to less blood flow to the brain. This can cause strokes and seizures. Moyamoya Disease: Causes & Effects
The brain tries to fix this by making new blood vessels. But these vessels can easily bleed.

Doctors first found moyamoya disease in Japan in the 1960s. Since then, they’ve learned a lot about it. It was thought to mainly affect people from East Asia. But now, research shows it can happen in many ethnic groups.
It’s still most common in Japan, Korea, and China.
Prevalence Around the World
Moyamoya disease is found in different parts of the world. It’s more common in Asia but also in North America and Europe. Scientists are looking into why some people get it more often.
| Region | Incidence Rate | Genetic Predisposition |
|---|---|---|
| Asia (Japan, Korea, China) | High | Strong |
| North America | Moderate | Variable |
| Europe | Low | Unclear |
Causes of Moyamoya Disease
Moyamoya disease comes from both genes and the environment. We don’t know all about it yet. But, we know genes play a big part in getting it.
Genetic Factors
A key finding is the link to the RNF213 gene mutation on chromosome 17. This is mostly seen in East Asian people. It shows genes matter a lot.
Seeing it in families shows it can run in families. This points to genes being a big factor in the disease.
Environmental Factors
Other things might also cause Moyamoya disease. These include radiation, head injuries, and certain infections. But, we need more studies to know for sure.
Looking into how genes and the environment work together is important. This will help us learn more about Moyamoya disease.
Symptoms of Moyamoya Disease
Moyamoya disease shows many symptoms that start small and get worse over time. It’s important to know these signs to catch it early. Moyamoya Disease: Causes & Effects
Early Warning Signs
At first, moyamoya disease shows up with short, temporary brain attacks called TIAs. These signs are often seen in kids. They include:
- Frequent headaches
- Seizures
- Developmental delays
Spotting these signs early helps stop more problems and get help fast.
Advanced Symptoms
As moyamoya gets worse, symptoms get more serious and varied. These can be:
- Uncontrolled movements
- Speech difficulties
- Sensory impairments
- Cognitive decline
In adults, moyamoya can lead to a stroke because the new blood vessels are fragile. Watching for these signs is key to good care and treatment.
How Moyamoya Disease is Diagnosed
Early diagnosis of moyamoya disease is key to managing it and preventing problems. Doctors use several tools and procedures to spot this disease.
Imaging Techniques
Magnetic resonance imaging (MRI) is a top way to find moyamoya disease. It shows detailed brain images. Doctors can check the blood vessels’ condition with MRI.
Moyamoya Disease: Causes & Effects Often, magnetic resonance angiography (MRA) is used with MRI. MRA shows how blood flows in the brain’s arteries. These tests together give a full view of the brain’s blood system. They help spot moyamoya early.
Digital subtraction angiography (DSA) is also key for diagnosing moyamoya. It’s the best way to see blood vessels and their flow. DSA shows the ‘puff of smoke’ sign that means moyamoya disease. Moyamoya Disease: Causes & Effects
Clinical Evaluations
Clinical tests are also important for diagnosing moyamoya. Doctors check how bad the symptoms are and their effects. They test thinking skills, movement, and other brain functions.
Using MRI, MRA, DSA, and clinical tests together gives a full view of moyamoya. This helps make a good treatment plan and helps patients get better.
Treatment Options for Moyamoya Disease
Treating Moyamoya disease often means surgery to help blood flow better to the brain. Direct bypass surgery is a key method. It connects an artery outside the brain to one inside, boosting blood flow right away. This surgery is complex but can greatly lower stroke risks.
Indirect bypass surgery is another way to treat it. It helps the body make new blood vessels over time. This method doesn’t work right away but can help improve blood flow slowly, easing symptoms and lowering stroke risks.
These surgeries are part of surgical revascularization. They aim to make new paths for blood to reach brain areas lacking enough oxygen and nutrients. These surgeries help manage symptoms and lower stroke risks but don’t cure Moyamoya disease.
| Type of Surgery | Procedure | Immediate Effect | Long-term Outcome |
|---|---|---|---|
| Direct Bypass Surgery | STA-MCA Bypass | Immediate | Significant, lasting improvement |
| Indirect Bypass Surgery | EDAS | Delayed | Gradual vascular growth and improvement |
There’s no cure for Moyamoya disease, but surgery can help a lot. Direct and indirect bypass surgeries are key in lowering stroke risks and managing the disease. It’s important for patients to see specialists and get the right treatment plan quickly.
Moyamoya Disease in Children vs. Adults
Moyamoya disease affects the blood vessels in the brain. It has different effects on children and adults. Kids and adults face different symptoms and treatment needs.
Differences in Symptoms
In pediatric moyamoya, kids often have seizures and delays in growth. They might have trouble moving and thinking clearly because of poor blood flow to the brain. Adults, however, might get severe strokes that cause bad headaches, eye problems, and trouble speaking. Moyamoya Disease: Causes & Effects
| Aspect | Children | Adults |
|---|---|---|
| Common Symptoms | Seizures, developmental delays, motor impairment | Hemorrhagic strokes, severe headaches, vision disturbances |
| Primary Complication | Ischemic events | Hemorrhagic strokes |
Variations in Treatment Approaches
Kids and adults with moyamoya need different treatments. For pediatric moyamoya, doctors often use methods that help new blood vessels grow. This is key for kids’ brain growth.
Adults might get treatments that fix blood flow problems right away. This helps prevent strokes and other serious issues. The goal is to match the treatment to the patient’s age and needs for the best results.
