Introduction to Moyamoya Disease
Moyamoya disease is a rare and serious neurovascular condition. It happens when arteries at the base of the brain get blocked or narrow. This leads to new blood vessels trying to make up for the lack of blood flow.
What is Moyamoya Disease?
The name “Moyamoya” comes from a Japanese word meaning “puff of smoke.” It describes the look of tiny, odd blood vessels seen in scans. These vessels form as a way to help with the blocked main arteries, which is a key part of Moyamoya disease.
Epidemiology of Moyamoya Disease
This disease mostly hits people in East Asia, like Japan, Korea, and China. But, it can also be found in other places, including the U.S. Studies show it’s becoming more common worldwide. Spotting it early is key because it can lead to a lot of strokes.
