The Moyamoya Disease – Symptoms Treatment
The Moyamoya Disease – Symptoms Treatment Moyamoya disease is a rare, progressive cerebrovascular disorder characterized by the narrowing or occlusion of arteries at the base of the brain, particularly the internal carotid arteries and their main branches. The term “moyamoya,” which means “puff of smoke” in Japanese, describes the appearance of abnormal collateral blood vessels that develop in response to arterial narrowing. These fragile, tangled vessels can lead to a range of neurological symptoms, primarily due to reduced blood flow to vital brain regions.
The Moyamoya Disease – Symptoms Treatment One of the most common symptoms of moyamoya disease is transient ischemic attacks (TIAs), often called mini-strokes. These are brief episodes of neurological dysfunction caused by temporary blood flow blockages. Patients might experience sudden weakness or numbness on one side of the body, difficulty speaking or understanding speech, and visual disturbances. As the disease progresses, strokes—either ischemic or hemorrhagic—may occur, leading to more severe neurological deficits such as paralysis, speech impairment, or cognitive decline.
Children with moyamoya may initially present with symptoms like repeated TIAs, seizures, or headaches. In adults, symptoms can also include dizziness, imbalance, or fainting spells. Because the symptoms can be vague and resemble other neurological conditions, diagnosis often requires a high index of suspicion. Imaging studies are crucial for confirming the disease. Magnetic Resonance Imaging (MRI) and Magnetic Resonance Angiography (MRA) can visualize the narrowing of arteries and the abnormal collateral vessels. Conventional cerebral angiography remains the gold standard, providing detailed images of blood flow and vessel structure, essential for planning treatment. The Moyamoya Disease – Symptoms Treatment
Treatment strategies for moyamoya disease aim to restore adequate blood flow to prevent strokes and reduce symptoms. Medical management alone is often insufficient, but it can include antiplatelet medications like aspirin to reduce the risk of clot formation. However, surgical intervention is generally considered the definitive treatment, especially in symptomatic patients. The most common procedures are revascularization surgeries, which create new pathways for blood to reach the brain tissue. The Moyamoya Disease – Symptoms Treatment
The Moyamoya Disease – Symptoms Treatment One widely performed surgery is direct bypass, where a scalp artery, such as the superficial temporal artery, is connected directly to a brain artery to bypass the narrowed segment. Indirect procedures involve placing vascular tissues on the brain surface to encourage new blood vessel growth over time. Often, surgeons combine both methods for optimal results.

Although surgery significantly reduces the risk of future strokes and alleviates symptoms, it does not cure the disease, which requires ongoing medical follow-up.
Living with moyamoya disease can be challenging, but advances in surgical techniques and improved diagnostic tools have enhanced outcomes considerably. Early diagnosis and prompt surgical treatment are vital for preventing severe neurological damage and improving quality of life. Patients diagnosed with moyamoya should work closely with a multidisciplinary team to develop a personalized management plan and receive the necessary support.
