Understanding : Risk Factors
Risk factors that doctors and researchers believe contribute to the formation of brain aneurysms:
- Smoking
- High blood pressure or hypertension
- Congenital resulting from inborn abnormality in artery wall
- Drug use, particularly cocaine
- Infection
- Tumors
- Traumatic head injury
- Family history of brain aneurysms
- Age over 40
- Gender, women compared with men have an increased incidence of aneurysms at a ratio of 3:2
- Other inherited disorders: Ehlers-Danlos Syndrome, Polycystic Kidney Disease, and Marfan Syndrome
- Presence of an arteriovenous malformation (AVM)Arteriovenous malformation (AVM)
A particular type of vascular malformation of the brain. An abnormal collection or tangle of arteries and veins located within the substance of the brain in which a maldevelopment of capillaries (which normally connect the arteries and veins) allows a high flow short cut through the brain.
Risk factors that doctors and researchers believe contribute to the rupture of brain aneurysms:
- Smoking
- High blood pressure or hypertension
