Yes, some congenital disorders increase the risk of getting a brain aneurysm. These include:
- Ehlers-Danlos syndrome. This is a connective tissue disorder that impairs blood vessels.
- Marfan's syndrome. This is another connective tissue disorder.
- Polycystic kidney disease. This disease increases blood pressure and leads to sacs of fluid in the kidneys.
- Unusually narrow aorta. The aorta delivers oxygenated blood to the heart from the body.
- Cerebral arteriovenous malformation (brain AVM). This condition causes malformed connections between the brain's arteries and veins, disrupting their normal blood flow.
