Overview of Moyamoya Disease
Moyamoya disease is a rare, serious neurological disorder characterized by narrowing or blockage of arteries at the brain’s base, prompting the formation of abnormal new blood vessels to compensate for reduced blood flow.
What is Moyamoya Disease?
The term “Moyamoya,” meaning “puff of smoke” in Japanese, refers to the appearance of small, tangled blood vessels seen on scans. These vessels develop as a compensatory response to blocked main arteries, a hallmark of Moyamoya disease.
Overview of Moyamoya Disease Epidemiology
High-Resolution MRI in Moyamoya Arterial Research This disease primarily affects East Asia—Japan, Korea, and China—but is also present in other regions, including the U.S. It’s spreading globally, and early detection is crucial, as it significantly increases stroke risk.
Understanding the underlying disease processes
Moyamoya disease results from genetic and environmental factors causing progressive arterial blockages. In response, fragile new blood vessels form, which can rupture and increase stroke risk, particularly in young individuals. Understanding its mechanisms aids doctors in developing improved treatments.
The Role of Imaging in Diagnosing Moyamoya Disease
Imaging plays a crucial role in diagnosing Moyamoya disease. Since its symptoms can be subtle and resemble other conditions, accurate imaging is essential for early detection and correct differentiation from other vascular disorders.
‘Difficulties in Diagnosis’
Diagnosing Moyamoya disease is challenging because its symptoms—such as transient ischemic attacks, strokes, or cognitive difficulties—mirror those of other brain conditions. To confirm the diagnosis, we rely on specialized imaging that reveals the characteristic features of Moyamoya.
Understanding Angiography
Cerebral angiography is the best method to visualize blood vessels in Moyamoya disease, providing detailed images that help doctors identify specific issues. However, it is an invasive procedure with associated risks.
