Symptoms of Moyamoya Disease

The greatest risk of Moyamoya disease is stroke, but it can cause a wide range of neurological symptoms, including:

  • Headache or dizziness
  • Weakness or paralysis in a limb or on one side of the body
  • Problems with speech — inability to speak or recall words
  • Sensory or cognitive impairment
  • Involuntary movements
  • Seizures or loss of consciousness
  • Vision problems

Some of these symptoms are signs of a stroke or transient ischemic attack (TIA), which requires immediate emergency treatment. Early diagnosis and treatment of Moyamoya is critical to avoid irreversible brain damage, so anyone experiencing these symptoms should be evaluated immediately.
