The primary treatments for moyamoya disease are revascularization procedures to restore blood flow to the affected region of the brain, explains the National Institute of Neurological Disorders and Stroke. While children typically respond better than adults, the majority of patients experience no further strokes or problems post-surgery.
In children, a stroke may be the first symptom of the disease, often accompanied by seizures or muscular weakness or paralysis on one side of the body. In adults, a hemorrhagic stroke due to recurring blood clots in the brain vessels may occur, notes the National Institute of Neurological Disorders and Stroke. Individuals suffering from the disorder may exhibit speech deficits, disturbed consciousness, involuntary movements, sensory and cognitive impairment, and vision problems.
