On Moyamoya and its treatment

Moyamoya disease is a progressive cerebrovascular disease in which certain arteries in the brain are constricted, causing a stroke. Collateral circulation develops around the blocked vessels to compensate for the blockage, but the collateral vessels are small, weak, and prone to hemorrhage, aneurysm, and thrombosis. Radiologically, these collateral vessels appear as a "puff of smoke." The name “moyamoya” means “puff of smoke” in Japanese.

Medically aspirin is usually prescribed, but permanent treatment is surgical.
