Even though it often hits kids, adults can get it too, says the American Stroke Association. Knowing a lot about moyamoya is important for doctors and patients. We will look into what causes it, its signs, and how to treat it.

Understanding Moyamoya Disease

Moyamoya Disease – Key Facts Moyamoya disease is a rare brain condition. It makes some brain arteries narrow and form new, weak blood vessels. These new vessels look like “puff of smoke”. This is why it’s called Moyamoya, from Japanese.

What is Moyamoya Disease?

It mostly hits kids and young adults, but can also affect older people. As arteries get blocked, new blood vessels form. These new vessels are weak and can bleed easily.

People with Moyamoya may have strokes, brief stroke-like episodes, or trouble thinking clearly.

History of Moyamoya Disease

The first time Moyamoya was described was in Japan in the late 1950s. In 1969, it got its name “Moyamoya” because of the tiny blood vessels seen in tests. Since then, lots of research has been done to learn more about it.

Groups like the National Institute of Neurological Disorders and Stroke and the Moyamoya Disease Foundation have helped a lot.

Epidemiology and Prevalence

Moyamoya is most common in East Asia, especially Japan and Korea. But it also happens in other places, like the U.S. It’s a rare disease, affecting about 3 to 10 people per 100,000.

It’s important to study because it affects blood vessels a lot. Studies show it’s more common in women and can happen at any age.

Causes of Moyamoya Disease

The exact cause of Moyamoya disease is still being studied. Genetic factors in Moyamoya are getting a lot of attention. It seems that family history might help explain why some people get this rare brain condition.

Researchers have found certain genes linked to Moyamoya disease. The RNF213 gene is a big clue in East Asian families. Other genes might also play a part, but we need more study.

Things like high blood pressure and diabetes might make Moyamoya worse. But we’re not sure how big of a role they play. We need more research to understand this better.

Some health issues seem to go hand in hand with Moyamoya disease. People with certain conditions like neurofibromatosis type 1 or sickle cell anemia are more likely to get Moyamoya. This could mean they have something in common with Moyamoya.

Moyamoya disease has many causes, including genes, health issues, and maybe even the environment. We need more research to figure out how these factors work together. This will help us find better ways to treat this serious condition.

Symptoms of Moyamoyo Disease

Moyamoya disease is a rare brain disorder. It has many symptoms that can change daily life. Knowing these signs helps get the right treatment fast, reducing serious problems.

Common Symptoms

Early signs of Moyamoya include headaches, mini-strokes, and feeling weak. People may also see things differently, have trouble speaking, and have seizures. These signs can look like other brain issues, making it hard to spot Moyamoya.

Advanced Symptoms

As Moyamoya gets worse, stroke signs become more clear and serious. These include muscle twitches, brain fog, and big trouble speaking. If left untreated, strokes can cause permanent harm. So, catching it early is key.

Symptoms in Children vs. Adults

Kids with Moyamoya often have mini-strokes that seem like seizures. They might also fall behind in school. Adults usually get full-blown strokes that can cause lasting brain damage. Knowing these differences helps doctors treat kids and adults right.

Spotting these symptoms early helps doctors find Moyamoya disease fast. This helps kids and adults get better care. Moyamoya Disease – Key Facts

Diagnosis of Moyamoya Disease

Doctors start by looking at the patient’s medical history and symptoms. This is key because Moyamoya disease gets worse over time. Finding it early and checking it closely is important for good care.

Initial Evaluation

First, doctors check the patient’s brain symptoms and stroke or TIA history. They also do a physical check to see if there are any signs of Moyamoya disease.

Imaging Tests

Tests like MRI and MRA help confirm Moyamoya disease. They show the brain’s blood vessels and look for blockages. Cerebral angiography is the best test for this disease. It gives clear pictures of the brain’s blood vessels.

Other Diagnostic Methods

Doctors also use other tests to see how Moyamoya disease affects blood flow in the brain. Cerebrovascular exams and cerebral perfusion studies check how well blood moves. This helps doctors understand the disease’s severity and decide on treatment.

Facts About Moyamoya Disease

Moyamoya disease is a rare condition that affects the brain’s arteries. It makes these arteries narrow. This can lead to strokes and other neurological problems.

It’s most common in East Asia but can happen anywhere in the world. The Moyamoya Disease Foundation says:

• In Japan, about 3.16 people out of 100,000 get it.
• In the U.S., it’s much rarer, affecting only about 0.086 people per 100,000.

Kids with Moyamoya disease may have strokes or brain attacks. This can hurt their brain development. The Journal of Cerebrovascular Diseases says:

• Up to 65% of people with Moyamoya may have more strokes if not treated.
• More than 10% of strokes in kids are from Moyamoya disease.
• Getting treatment early can stop severe brain problems.

The Rare Diseases Clinical Research Network wants more research on Moyamoya disease. Early surgery can lower stroke risk and help patients more. We need better treatments to fight this disease and help patients live better lives.

Treatment Options for Moyamoya Disease

Treatment for Moyamoya disease is key to manage symptoms and stop strokes. We look at medical and surgical ways to treat it. These include medical therapy, surgery, and steps for getting better after surgery.

Medical Management

Doctors use medicine to help Moyamoya disease. They give blood thinners like aspirin to help blood flow better and prevent clots. They might also use calcium channel blockers to help with headaches. Moyamoya Disease – Key Facts

Surgical Options

Surgery is often needed to help Moyamoya disease. This surgery makes new paths for blood to flow. It can be done in two ways: indirect and direct.

Indirect surgery makes new blood vessels. Direct surgery connects arteries directly to improve blood flow.

Post-surgical Care

Getting better after surgery is very important for Moyamoya disease. Doctors check on you often and use scans to see how things are going. They also want to see if new blood vessels are forming.
