Moyamoya disease is a chronic and progressive condition of the arteries in the brain. People with moyamoya disease have narrowing of these blood vessels that leads to blockages and can eventually cause ischemic stroke, hemorrhagic stroke, and seizures. The causes of moyamoya disease are unknown. However, it is known that the disorder may appear as an isolated, primary disorder that may have genetic determinants or may occur in association with a number of different underlying disorders, as noted above. Moyamoya disease most commonly affects children, but adults may have the condition
Moyamoya Disease Symptoms
- Recurring transient ischemic attacks (TIAs or “mini-strokes”)
- Headache
- Epilepsy
- Stroke: Ischemic stroke (due to blockage) or hemorrhagic stroke (bleeding)
- Hemiparesis: weakness or paralysis on one side of the body
- Progressive difficulty in thinking and remembering due to repeated strokes and bleeding
In diagnosing moyamoya disease, the doctor may recommend an electroencephalogram, or EEG, which may show a characteristic electrical pattern when the person is asked to breathe heavily. Other neuroimaging, including computed tomography (CT) and magnetic resonance imaging (MRI) of the brain are also important tests. A brain scan using angiography or ultrasound may also reveal problems with blood flow to the brain and help doctors identify any vessels that are stiffened or blocked.
Moyamoya disease treatment involves managing symptoms, improving blood flow to the brain and controlling seizures. Blood thinners can help avoid clots and blockages, but can also increase the risk of bleeding. The doctor will carefully assess each patient’s unique situation in recommending any medicines.
In some cases, revascularization can help. This is surgery to rebuild the blood supply to the underside of the brain, a delicate procedure that should be performed by an experienced vascular neurosurgeon. In the postoperative period, pain control and careful monitoring of the patient are essential to avoid a stroke.
