What are symptoms you have with an avm?

AVM SYMPTOMS: Avms can present with headaches and seizures while at least 15% of the population at detection have no symptoms. Half of patients with avm present with hemorrhage as the first symptom. Symptoms due to bleeding include loss of consciousness, headache, nausea, vomiting, incontinence, speech, movement or sensory loss, and blurred vision.

Depends on location: Avms can present with hemorrhage or seizure. If the avm is located close to the motor region, they can also present with focal weakness because of ischemia from the "steal" phenomenon associated with the avm.

Multiple or none: Many avm's are silent and people never know they have them until they bleed. 30% of people with avm's will present with seizures. You may have headaches, strokes, visual symptoms, weakness, or other symptoms.

Depends on location: Avms may present with a bleed, which may be manifest as a headache or alteration in level of consciousness. Patients may also present with a seizure. This is from the ischemia to the surrounding brain as most of the blood to the area is going to the avm rather than the brain. Focal motor deficits may occur if the avm causes adjacent brain (motor area) to suffer from a shunting of blood to the avm.
