An AVM may occur in the brain, brainstem, or spinal cord and is caused by abnormal development of blood vessels. The most common symptoms of AVM include hemorrhaging (bleeding), seizures, headaches, and neurological problems such as paralysis or loss of speech, memory, or vision. Is there any treatment?
