What are the symptoms of Moyamoya Disease?

 In children, the first symptom of Moyamoya disease is often stroke, or recurrent transient ischemic attacks (TIA, commonly referred to as “mini-strokes”), frequently accompanied by muscular weakness or paralysis affecting one side of the body, or seizures

 

Adults most often experience a hemorrhagic stroke due to recurring blood clots in the affected brain vessels.  

 

Individuals with this disorder may have disturbed consciousness, speech deficits (usually aphasia), sensory and cognitive impairments, involuntary movements, and vision problems.  Because it tends to run in families, researchers think that Moyamoya disease is the result of inherited genetic abnormalities.  Studies that look for the abnormal gene(s) may help reveal the biomechanisms that cause the disorder.
