Overview of Moyamoya Disease
Moyamoya disease is a rare neurological disorder characterized by narrowing or blockage of arteries at the brain‘s base, leading to reduced blood flow. The name, meaning “puff of smoke” in Japanese, refers to the tangled appearance of abnormal blood vessels observed in imaging.
Small vessels develop a complex network to compensate for reduced blood flow caused by the narrowing of main arteries. Exploring Current Treatments for Moyamoya Disease
What Is Moyamoya Disease?
Moyamoya disease causes narrowing of the internal carotid arteries and their branches, prompting the formation of numerous small collateral vessels. This compensatory blood flow is unstable and increases the risk of strokes.
While it mainly affects children, adults can also be impacted, making it a significant risk at any age.
Signs and Identification
Moyamoya disease symptoms can be subtle, often resembling mild strokes, headaches, or seizures. Common signs include sudden weakness, numbness, speech difficulties, and vision issues.
Early diagnosis of Moyamoya disease is crucial. MRI and angiography are essential tests that reveal the characteristic “puff of smoke” appearance and assess cerebral blood flow.
These tests are essential for developing treatment plans. According to the American Heart Association, they allow doctors to assess the severity and progression of the disease, guiding appropriate treatment decisions.
