What is Moyamoya disease and why is it linked to Japanese genes?

Moyamoya disease is a rare cerebrovascular disorder where brain arteries narrow, causing the brain to form fragile new vessels. It shows the highest prevalence in Japan, though the exact genetic link is still studied.

Can stroke-like symptoms be misdiagnosed as stress?

Yes, transient neurological attacks resembling strokes, like numbness or weakness, can be mistaken for stress or anxiety, delaying diagnosis for conditions like Moyamoya disease.

What treatment is available for Moyamoya disease?

Surgical revascularization is a key treatment for Moyamoya disease, aiming to restore safe blood flow to the brain and reduce the risk of strokes and hemorrhages.

Neurosurgeon Reveals Mysterious 'Puff of Smoke' Brain Disease

A rare and serious neurological condition, Moyamoya disease, is being brought to light by a neurosurgeon, noting its significantly higher prevalence in Japan. This disorder causes the brain to create an unexpected "backup plan" by forming a network of fragile collateral vessels when blood flow is reduced.

Patients often experience transient, stroke-like episodes, including facial numbness and speech difficulties, which can be easily dismissed as stress or anxiety due to their temporary nature. Diagnostic imaging, such as cerebral angiography, reveals a distinctive pattern that neurosurgeons recognize as Moyamoya, a Japanese term for "a puff of smoke" due to the appearance of these new vessels.

These delicate blood vessels are prone to rupture, leading to ischemic strokes and hemorrhages. Fortunately, specialized surgical intervention, known as revascularization, can restore adequate blood supply to the brain, significantly lowering the patient's future risk of these dangerous events. Early recognition and treatment are vital.
