Article Excerpts about Moyamoya Disease

Moyamoya disease is a rare, progressive cerebrovascular disorder characterized by the narrowing or occlusion of major blood vessels leading into the brain, and the formation of abnormal blood vessels called moyamoya vessels. First described in Japan in the 1960ís, the disease has since been found in the United States, Europe, Australia, and Africa. (Source: excerpt from NINDS Moyamoya Disease Information Page: NINDS)

Definitions of Moyamoya Disease:

A chronic cerebral vasculopathy primarily occurring in childhood and characterized by slowly progressive carotid artery narrowing and occlusion at the base of the brain. An extensive network of anastomoses forms between branches of the carotid arteries, resulting in a characteristic angiographic appearance. The condition may be idiopathic (classic moyamoya disease) or occur in association with ANEMIA, SICKLE CELL; DOWN SYNDROME; CRANIOCEREBRAL TRAUMA; RADIOTHERAPY induced arterial injury; NEUROFIBROMATOSIS; and other diseases. Clinical manifestations include hemiparesis, headache, seizures, and delayed mental development. In older individuals, this disease may present as SUBARACHNOID HEMORRHAGE. (From Adams et al., Principles of Neurology, 6th ed, p831; Clin Neurol Neurosurg 1997 Oct;99 Suppl 2:S36-8) - (Source - Diseases Database)

Moyamoya Disease is listed as a "rare disease" by the Office of Rare Diseases (ORD) of the National Institutes of Health (NIH). This means that Moyamoya Disease, or a subtype of Moyamoya Disease, affects less than 200,000 people in the US population.

Ophanet, a consortium of European partners, currently defines a condition rare when it affects 1 person per 2,000. They list Moyamoya Disease as a "rare disease".
