Knowing your risk for a brain aneurysm

Sometimes, the blood vessels in the brain can develop a weakened section that can bulge outward. This is a brain aneurysm . Some people with a brain aneurysm don’t know they have it, and it causes no problems. However, if a brain aneurysm ruptures, it’s a potentially life-threatening medical problem that requires emergency care. If you develop any possible signs of a ruptured brain aneurysm, such as an excruciating headache, stiff neck and blurry vision, call 911 immediately. The neuroscience specialists at Good Samaritan Hospital are here to help.

Risk factors of brain aneurysms that are present at birth
Some risk factors of brain aneurysms aren’t modifiable with lifestyle changes. For instance, your family history might raise your risk of this health problem. Watch this video to hear a neurosurgeon at Good Samaritan Hospital explain how genetics influences aneurysm risk.

Cerebral arteriovenous malformation is a condition that affected patients are usually born with. It’s a tangle of blood vessels in the brain that features abnormal connections to other nearby blood vessels. Over time, this abnormality can cause damage that may lead to an aneurysm.

Other risk factors that are present at birth include:

  • Atypically narrow aorta
  • Polycystic kidney disease
  • Inherited connective tissue disorders that result in weak blood vessels

Risk factors of brain aneurysms that are acquired
Acquired risk factors are those that develop over the course of the patient’s lifetime. People who are older may be at a higher risk of brain aneurysms. A head injury may lead to an aneurysm, as can some blood infections.

One of the most impactful risk factors is smoking . It isn’t known exactly why smoking can lead to brain aneurysms, but it’s thought that the damage done to blood vessels plays a role. Other substances of abuse can raise the risk, including illicit drugs like cocaine and the heavy consumption of alcohol.

High blood pressure is another acquired risk factor. It’s manageable with a healthy diet and regular exercise, and sometimes medications.
