Do I have Moyamoya?

Moyamoya disease is a rare cerebrovascular disorder that affects the blood vessels in the brain. It is characterized by the narrowing or blockage of the internal carotid arteries, which are major blood vessels responsible for supplying oxygen-rich blood to the brain. As a result, the brain compensates by forming tiny blood vessels, resembling a "puff of smoke" in Japanese (which is what "Moyamoya" means).



Recognizing the symptoms:


Identifying the signs of Moyamoya disease can be challenging as they can vary from person to person. However, there are some common symptoms to be aware of:




  • Recurrent strokes: Individuals with Moyamoya disease are prone to experiencing recurrent strokes, especially at a young age. These strokes may cause weakness or paralysis on one side of the body, difficulty speaking, or loss of consciousness.

  • Transient ischemic attacks (TIAs): TIAs, also known as mini-strokes, are temporary episodes of reduced blood flow to the brain. They can manifest as sudden weakness, numbness, or difficulty speaking, lasting for a few minutes to hours.

  • Seizures: Some individuals with Moyamoya disease may experience seizures, which are abnormal electrical activities in the brain. Seizures can cause convulsions, loss of consciousness, or unusual sensations.

  • Headaches: Chronic headaches, often described as migraines, can be a symptom of Moyamoya disease. These headaches may be accompanied by other neurological symptoms.

  • Cognitive and developmental issues: Children with Moyamoya disease may exhibit cognitive impairments, such as learning difficulties, memory problems, or developmental delays.



Getting a diagnosis:


If you suspect you may have Moyamoya disease based on the symptoms mentioned above, it is crucial to consult a medical professional for a proper diagnosis. The diagnostic process typically involves:




  • Medical history and physical examination: Your doctor will review your medical history, including any previous strokes or neurological conditions. They will also conduct a thorough physical examination to assess your neurological function.

  • Imaging tests: Various imaging techniques are used to visualize the blood vessels in the brain. These may include magnetic resonance imaging (MRI), magnetic resonance angiography (MRA), computed tomography (CT) scan, or cerebral angiography. These tests help identify the characteristic narrowing or blockage of the blood vessels seen in Moyamoya disease.

  • Genetic testing: In some cases, genetic testing may be recommended to check for specific gene mutations associated with Moyamoya disease.



Seeking treatment:


Once diagnosed with Moyamoya disease, it is essential to discuss treatment options with a healthcare professional. The primary goal of treatment is to improve blood flow to the brain and prevent further strokes. Treatment options may include:




  • Medications: Certain medications, such as antiplatelet agents or blood thinners, may be prescribed to reduce the risk of blood clots and strokes.

  • Surgical interventions: Revascularization surgeries are commonly performed to bypass the blocked or narrowed blood vessels. These procedures aim to restore blood flow to the brain by creating new pathways for blood circulation.

  • Supportive care: Rehabilitation therapies, including physical therapy, occupational therapy, and speech therapy, may be recommended to manage any neurological deficits resulting from strokes.



Conclusion:


If you experience recurrent strokes, TIAs, seizures, chronic headaches, or cognitive issues, it is important to consult a healthcare professional for a proper evaluation. While this information provides an overview of Moyamoya disease, only a qualified medical expert can diagnose the condition and recommend appropriate treatment options.
