CM-AVM stands for cerebral arteriovenous malformation, which is a tangle of abnormal blood vessels in the brain. These malformations can cause a range of symptoms depending on their size, location, and whether they are bleeding.
Common Symptoms of CM-AVM:
- Headache: This is the most common symptom, often described as severe, throbbing, and sudden.
- Seizures: These can range from mild to severe and may be the first sign of a CM-AVM.
- Weakness or Numbness: This can occur in the arms, legs, or face, depending on the location of the AVM.
- Vision Problems: Blurred vision, double vision, or loss of vision can occur if the AVM affects the visual pathways.
- Speech Problems: Difficulty speaking or understanding language can occur if the AVM affects the language centers of the brain.
- Balance Problems: Dizziness, vertigo, or difficulty walking can occur if the AVM affects the cerebellum, which controls balance.
- Mental Changes: Confusion, memory problems, or personality changes can occur if the AVM affects the frontal lobe.
Symptoms of Bleeding:
- Sudden, Severe Headache: This is often described as the "worst headache of my life."
- Vomiting: This can be a sign of increased pressure in the brain.
- Loss of Consciousness: This can range from brief periods of confusion to a coma.
- Neck Stiffness: This can occur due to irritation of the meninges, the membranes surrounding the brain.
Diagnosis and Treatment:
If you experience any of these symptoms, it is important to see a doctor right away. A diagnosis of CM-AVM is usually made through a combination of imaging tests, such as MRI and angiogram. Treatment options include surgery, radiation therapy, or endovascular embolization.
