Moyamoya

Moyamoya is a disease marked by constricted or blocked arteries at the base of the brain. Moyamoya is Japanese for "puff of smoke" and refers to the appearance of small blood vessels that form to compensate for blocked arteries.

Moyamoya can cause strokes, ministrokes (transient ischemic attacks), aneurysms, or bleeding in the brain. There are no medications that can treat the condition, but surgery can improve or restore blood flow to the brain.
