It is considered to be an abnormal tangle of blood vessels connecting arteries and veins, which interrupts normal blood flow and oxygen circulation.

This condition can be diagnosed in an emergency situation, immediately after bleeding (hemorrhage) or a seizure. It can also be detected after doing a CT scan for other symptoms. It results in rupture and bleeding from arteriovenous malformation in the brain as it puts too much pressure on the walls of the affected arteries and veins, causing them to become thinner or weaker.
