The presence of an arteriovenous malformation in the brain can lead to which significant risk?

The presence of an arteriovenous malformation (AVM) in the brain is associated with the significant risk of sudden bleeding. An AVM is a tangled network of blood vessels that can disrupt normal blood flow and may cause pressure to build up. This can lead to the rupture of the vessels, resulting in hemorrhage, which can be life-threatening and requires immediate medical attention. Hemorrhagic stroke due to an AVM can cause severe neurological deficits, increased intracranial pressure, and other complications.

In contrast, options such as increased cognitive function, enhanced motor skills, and stable intracranial pressure do not accurately reflect the risks associated with AVMs. AVMs can compromise brain function and overall health, making the possibility of sudden bleeding a critical concern for individuals affected by these vascular malformations.
