It affects the areas between [[Artery|arteries]] and [[vein]]s, and bypasses the [[capillary]] system. This happens in the [[central nervous system]] (usually [[cerebral arteriovenous malformation|cerebral AVM]]), but may appear in any location. The disease can cause intense pain or bleeding or lead to other serious medical problems such as [[cerebral hemorrhage]]s or [[stroke]]s. AVMs are usually [[congenital]]. The genetic patterns of AVMs are incomplete, but there are known genetic [[mutations]].<ref>{{cite web|url=http://www.ninds.nih.gov/disorders/avms/detail_avms.htm#102083052|title=National Institute of Neurological Disorders and Stroke|website=nih.gov|access-date=17 March 2018|archive-date=5 December 2016|archive-url=https://web.archive.org/web/20161205043316/http://www.ninds.nih.gov/disorders/avms/detail_avms.htm#102083052|url-status=dead}}</ref> The general symptoms of a cerebral AVM include [[headache]]s and [[epilepsy|epileptic seizures]].
