Understanding Moyamoya Disease: Symptoms, Diagnosis, and Treatment Options

Moyamoya Disease is a rare and progressive condition characterized by the narrowing or blockage of the blood vessels in the brain that supply oxygen and nutrients to the brain cells, leading to weakened blood flow and an increased risk of stroke. In this article, we will explore the symptoms, diagnosis, and treatment options available for Moyamoya Disease.

Symptoms of Moyamoya Disease

The symptoms of Moyamoya Disease can be variable and may depend on the severity of the disease. Common symptoms include:

– Headaches
– Seizures
– Weakness or numbness on one side of the body
– Difficulty speaking or understanding speech
– Vision problems
– Cognitive decline
– Transient ischemic attack (TIA) or mini-stroke
– Confusion
– Paralysis or loss of consciousness

These symptoms may progressively worsen over time and can result in a stroke or permanent disability if left untreated.

Diagnosis of Moyamoya Disease

To diagnose Moyamoya Disease, a neurologist or neurosurgeon will perform a series of medical tests. These tests may include:

– Physical exam and medical history
– Magnetic resonance imaging (MRI)
– Computed tomography (CT)
– Angiogram or arteriogram
– Transcranial doppler (TCD)
– Blood tests

Further evaluations may be needed to determine the extent and severity of the disease and the best course of treatment.

Treatment Options for Moyamoya Disease

The treatment for Moyamoya Disease typically depends on the severity and progression of the disease. Medical treatment may include medications to prevent blood clots and reduce the risk of stroke, such as antiplatelet agents and anticoagulants. In severe cases, surgical intervention may be necessary.

Surgical options for Moyamoya Disease may include:

– Direct bypass surgery: This involves creating a new blood vessel to bypass the narrowed or blocked blood vessel.
– Indirect bypass surgery: This involves redirecting blood flow to the brain by creating new blood vessels outside the brain.
– Endovascular treatment: This may involve using a catheter to access the blocked blood vessel and inserting a stent or balloon to widen the vessel.


Moyamoya Disease is a rare and progressive disease that requires early diagnosis and prompt treatment to reduce the risk of stroke and permanent disability. Early symptoms may include headaches, seizures, and weakness or numbness on one side of the body. Diagnosis typically involves a series of medical tests, including imaging and blood tests. Treatment options may include medications, surgical intervention, or a combination of both.

It is important to seek medical attention promptly if you or a loved one experience any symptoms of Moyamoya Disease. With proper medical care, individuals with this condition can lead healthy and fulfilling lives.
