What is Moyamoya Disease?

Hello everyone! Today, we're going to talk about Moyamoya disease. Moyamoya disease is a type of cerebrovascular disorder that causes various symptoms due to insufficient blood flow to the brain. This condition was first named by Professor Suzuki of Japan. As the name suggests, it's characterized by a hazy, wispy network of blood vessels resembling a puff of smoke.

Symptoms of Moyamoya Disease

Moyamoya disease occurs when the blood vessels supplying the brain narrow. The symptoms can differ between children and adults. In children, it often manifests as cerebral ischemia or stroke, while in adults, cerebral hemorrhage is more common. Key symptoms include:

• Seizures
• Headaches
• Involuntary movements
• Cognitive decline
• Vision or speech impairment

In children, symptoms like paralysis in the arms or legs may appear after consuming hot food or experiencing strong emotional changes. If these symptoms occur, seek medical attention immediately.

Causes of Moyamoya Disease

The exact cause of Moyamoya disease is still unknown. While there's debate about whether it's acquired or congenital, there are currently no known preventive measures. Research suggests that genetic factors may play a larger role than environmental factors. A Japanese study also indicated that occupation or lifestyle habits don't significantly influence its development, so individuals with a family history should consider getting tested.

Treatment for Moyamoya Disease

Treatment for Moyamoya disease can be broadly categorized into conservative treatment and surgical treatment. Surgical options include direct revascularization, which connects blood vessels to increase blood flow, and indirect revascularization, which takes time but also helps increase blood flow. The most commonly performed and least risky method currently is indirect revascularization, where blood vessels from the scalp or muscles are placed on the surface of the brain to encourage the growth of new blood vessels.

Even after surgery, regular check-ups are necessary for at least 4 to 5 years. If symptoms reappear, seek immediate medical attention for further examination.

Important Precautions for Moyamoya Disease

Moyamoya disease can lead to a state of blood deficiency, so it's crucial to avoid situations that exacerbate this. Hyperventilation or stress can alter blood supply, leading to imbalances in circulation. Maintaining mental and physical stability is extremely important.

Currently, Moyamoya disease is difficult to cure with modern medicine. However, appropriate surgical treatments can alleviate symptoms and prevent disability. Health is our most precious asset, so always be mindful of it!
