What are the symptoms of Arteriovenous Malformations?


The symptoms of AVMs vary depending on their type and location. While migraine-like headaches and seizures are general symptoms, most AVMs do not show symptoms until a bleed occurs. Common signs of brain AVMs include a sudden onset of a severe headache, vomiting, a stiff neck, seizures, migraine-like headaches or a Bruit; an abnormal swishing or ringing sound in the ear caused by blood pulsing through the AVM.
