What is Moyamoya Disease?
Moyamoya disease and other forms of intracranial stenosis cause the progressive narrowing of vessels in the brain. This can cause transient ischemic attacks (TIAs) and stroke. Over time, patients may develop severe headaches, TIAs and strokes leading to neurological problems, including vision, speech, movement and sensation problems. Moyamoya can appear at any age. Although it is considered a rare disease, it is often misdiagnosed.
The treatment of moyamoya and intracranial stenosis begins with radiological studies to confirm the diagnosis and plan for treatment. Moyamoya patients are started on aspirin and asked to stay well hydrated. The definitive treatment for moyamoya is direct cerebral bypass. Patients can go on to live normal, healthy lives following direct cerebral bypass. This surgery dramatically reduces the risk of stroke in moyamoya patients.
Patients are evaluated and treated in our Cerebral Revascularization Program in the Department of Neurosurgery. The Penn State Cerebral Revascularization Program is one of a few programs in the country that specialize in the treatment of moyamoya with direct bypass.
