Causes and Diagnoses
Causes and Diagnoses of Moyamoya Disease
Although the cause is currently unknown, researchers think moyamoya may be an inherited genetic condition because it tends to run in families.
Northwestern Medicine specialists offer diagnostic tests, including a physical and neurological exam, and provide a review your family medical history. We may also provide diagnostic procedures that include:
- Computed tomography (CT) scan: This test can show bleeding in the brain or damage to brain cells caused by a stroke, and may also reveal any artery conditions that may have caused the symptoms.
- Magnetic resonance imaging (MRI): Images from this test can reveal changes in brain tissue from the stroke.
- Doppler ultrasound: This special ultrasound shows the speed and direction of blood flow through the blood vessels.
- Positron emission tomography (PET) scan: This test examines various body tissues to identify certain conditions by looking at blood flow, metabolism and oxygen use.
If you are diagnosed with moyamoya disease, we will work with you and your primary care physician to tailor treatment to your individual condition.
