Moyamoya disease is a rare and progressive cerebrovascular disorder that causes the narrowing or blockage of the blood vessels in the brain. It primarily affects children and young adults, with a higher prevalence rate among females. In this article, we will discuss the symptoms, causes, and treatment of Moyamoya disease to help improve your understanding of this condition.

– Autoimmune disorders: In rare cases, Moyamoya disease may be associated with autoimmune disorders such as lupus and scleroderma.
– Radiation exposure: Exposure to ionizing radiation, particularly during childhood, may increase the risk of Moyamoya disease.

Treatment for Moyamoya Disease

The primary goals of treatment for Moyamoya disease are to prevent strokes and relieve symptoms. Depending on the severity of the condition, the treatment options may include:

– Medications: Blood thinners and antiplatelet drugs may be prescribed to prevent blood clots and reduce the risk of strokes.
– Surgical procedures: Direct or indirect revascularization surgery may be necessary to improve blood flow to the brain and prevent further damage to brain tissue.
– Symptomatic treatment: Headache medications, anticonvulsants, and speech therapy may be prescribed to manage symptoms associated with Moyamoya disease.
