Moyamoya Disease – RSNA Insights
Moyamoya Disease – RSNA Insights Moyamoya disease is a rare condition that mainly affects kids but can also happen to adults. It’s a type of brain problem that makes the blood vessels in the brain get narrower. This means less blood flows and can make brain images look like a “puff of smoke”. The NIH says this unique look on scans is key for finding out what’s wrong and how to treat it.
The RSNA is leading the way in finding out more about Moyamoya disease through imaging research. They use new imaging methods and studies to help us understand this tricky brain condition better.
Let’s look closer at Moyamoya disease. We’ll talk about its signs, causes, how doctors figure it out, and the newest ways to treat it. See how RSNA’s research is helping us find new ways to deal with this complex brain issue.
Introduction to Moyamoya Disease
Moyamoya disease is a rare condition that affects the brain’s blood flow. It happens when arteries at the brain’s base get blocked or narrowed. This blockage makes tiny new blood vessels grow, looking like “puff of smoke” on scans. That’s where the name “Moyamoya” comes from.
What is Moyamoya Disease?
Moyamoya definition is a special blood vessel problem that affects the brain. It reduces blood flow to the brain. This can cause short-term brain attacks or even strokes. So, finding it early and treating it is very important.
Historical Background
In the 1960s, doctors in Japan first found Moyamoya. The name “Moyamoya” means “puff of smoke” in Japanese, from the look of tangled blood vessels on scans. At first, it was mainly found in Japan. Now, it’s known as a rare but serious brain blood vessel problem all over the world.
| Aspect | Details |
|---|---|
| First Discovery | 1960s in Japan |
| Etymology | “Moyamoya” means “puff of smoke” in Japanese |
| Nature | Cerebrovascular Disorder |
| Global Recognition | Known worldwide, especially in East Asia and North America |
Symptoms of Moyamoya Disease
Moyamoya disease shows many symptoms, in early and late stages. It’s key to spot these signs early for quick medical help. The way Moyamoya shows up can be different in kids and adults, affecting how doctors treat it.
Early Symptoms
At first, Moyamoya disease might cause headaches or seizures. These signs are often small and might seem like other things. Watching for signs like mini-strokes is key to catching it early.
Advanced Symptoms
As it gets worse, Moyamoya can lead to more serious issues. This includes more strokes or brain bleeds. People may lose brain function and think less clearly, really hurting their life quality. Stroke risk goes up, so quick doctor help is needed.
Symptoms in Children vs. Adults
Children and adults show Moyamoya symptoms in different ways:
| Children | Adults | |
|---|---|---|
| Common Symptoms | Growth delay, frequent transient ischemic attack (mini-strokes), and seizures | Recurrent strokes, cognitive decline, and migraines |
| Neurological Impact | Delayed development and learning difficulties | Memory loss and impaired judgment |
| Frequency of Stroke | High, due to undetected progression | Moderate to high, often due to underlying ischemic events |
Knowing these differences helps doctors give the best care for kids and adults with Moyamoya. Getting advice from places like the Mayo Clinic and the American Heart Association helps make treatment better for everyone.
Causes and Risk Factors
Understanding the Moyamoya etiology is key for finding out what’s wrong and how to fix it. This disease often comes from both genes and the environment. It’s more likely to happen if you have a family history of it.
A big clue to Moyamoya disease is a certain gene called RNF213. Human Molecular Genetics found that changes in this gene make Moyamoya more likely. This is especially true for people from East Asia.
Other things that might make you more likely to get Moyamoya include certain syndromes. These include Down syndrome and neurofibromatosis type 1. This shows how genes and other health issues can work together.
Looking at what causes Moyamoya also means thinking about lifestyle and environment. Things like smoking, being overweight, and high blood pressure don’t directly cause it. But they might make it worse or make you more likely to have a stroke.
To wrap up, Moyamoya disease has many risk factors and genetic parts. The table below shows the main points from studies in the Stroke journal and Genetics in Medicine.
| Factor | Description | Source |
|---|---|---|
| RNF213 Gene Mutation | Significant risk factor prevalent in East Asian populations | Human Molecular Genetics |
| Genetic Predisposition | Family history increases the likelihood of disease onset | Genetics in Medicine |
| Associated Syndromes | Conditions like Down syndrome and neurofibromatosis type 1 | Stroke Journal |
| Environmental Factors | Exacerbate disease progression or increase stroke risk | Stroke Journal |
Diagnostic Criteria
Getting a correct Moyamoya disease diagnosis is key. It needs a full check-up and advanced scans. These steps help confirm the disease and plan treatment.
Clinical Evaluation
The first step in diagnosing Moyamoya is looking at the patient’s history and symptoms. Doctors check for signs like frequent short brain attacks, strokes, and headaches. They also look for signs of brain damage, thinking problems, and other clues.
Imaging Techniques
Moyamoya Disease – RSNA Insights Scans are very important for diagnosing Moyamoya. They look for specific signs like blocked arteries and new blood vessel growth.
Common scans used are:
- Magnetic Resonance Imaging (MRI): This scan shows detailed brain pictures. It helps see how much arteries are blocked and new blood vessels are formed.
- Cerebral Angiography: This is the top choice for seeing blood vessels clearly. It shows the changes in blood vessels that happen with Moyamoya.
These scans are key to meeting the imaging criteria for Moyamoya. They show the signs that tell us it’s Moyamoya. Studies in top journals like the American Journal of Neuroradiology and The Lancet Neurology help us learn more about these scans.
Imaging Techniques for Moyamoya Disease
Moyamoya Disease – RSNA Insights Getting a clear picture of Moyamoya disease is key. We use different ways to see the blood vessels in the brain. Here are three main methods we use.
Magnetic Resonance Imaging (MRI)
MRI in Moyamoya shows us the brain and its blood vessels clearly. It often comes with Magnetic Resonance Angiography (MRA). This combo is great at spotting the “puff of smoke” look of bad vessels. It also checks for brain damage or stroke, which Moyamoya patients often get.
Computed Tomography (CT) Scan
The CT scan utility is fast for checking the brain in emergencies. It’s good at finding strokes or bleeding quickly. Even though it’s not as detailed as MRI, it gives important info fast.
Cerebral Angiography
A cerebral angiogram for Moyamoya is the top choice for finding out what’s going on. This method shows blood flow in detail, highlighting blockages and new paths. It confirms the disease and helps plan treatments, giving a clear view that other methods can’t match.
| Technique | Advantages | Limitations |
|---|---|---|
| MRI with MRA | High resolution, detailed visualization, non-invasive | Longer scan time, higher cost |
| CT Scan | Quick, widely available, good for emergencies | Lower detail compared to MRI, radiation exposure |
| Cerebral Angiography | Definitive diagnostic tool, detailed vessel mapping | Invasive, higher risk of complications |
Using these imaging methods helps us understand and treat Moyamoya disease better. This leads to better care for patients and smarter treatment plans.

Surgical Revascularization
Surgery is often needed to make sure blood flows well to the brain. There are two main types of surgery. Direct bypass connects arteries directly. Indirect methods help new blood vessels grow.
Let’s look at the two surgery types:
| Method | Procedure | Advantages | Challenges |
|---|---|---|---|
| Direct Bypass (STA-MCA) | Immediate connection of external artery to brain artery | Immediate blood flow improvement | Technically demanding, risk of perioperative stroke |
| Indirect Bypass (EDAS) | Encourages new vessel growth over time | Less technically challenging, lower perioperative risk | Gradual improvement, slower onset of benefits |
Post-Treatment Care and Follow-Up
Getting better from Moyamoya disease takes a lot of work. It’s important to take good care after treatment to keep symptoms under control. This part will talk about how to get better after surgery and why checking up is key.
Rehabilitation
Rehab after Moyamoya surgery helps patients get stronger, move better, and think clearer. It includes physical, occupational, and speech therapy. Studies say these therapies really help patients live better by fixing their brains and bodies.
- Physical Therapy: Helps with moving and building muscle strength.
- Occupational Therapy: Makes it easier to do everyday tasks and be independent.
- Speech Therapy: Fixes any trouble with talking that the disease or treatment caused.
Monitoring and Future Imaging
Keeping an eye on patients is key to catching problems early. Regular scans like MRI and CT are very important. They show how blood flows and if blood vessels are okay, helping doctors act fast.
Studies in the International Journal of Stroke and the Stroke Rehabilitation Journal stress the need for regular scans. They show how important it is to change treatment plans based on what scans show. Moyamoya Disease – RSNA Insights
