What is a brain aneurysm?

A brain aneurysm forms if a weakened site in the arterial wall of the brain protrudes and becomes filled with blood. This is a dangerous condition that can affect individuals of all ages. Once it ruptures, it is considered as an emergency that can result to brain damage, stroke and even death if not promptly treated.

What are the causes?

There are certain circumstances that increases the development or rupture of a brain aneurysm. The following factors might instigate the rupture of an existing aneurysm:

  • Intense anger
  • Excessive exercise
  • Consumption of soda or coffee
  • Straining during bowel movements
  • Being startled
  • Sexual activity

    Headache or aching sensation behind or above the eye that can be minor or severe.

What are the signs of a brain aneurysm?

A brain aneurysm is considered unpredictable and might not cause any symptoms until they rupture. Large-sized or ruptured aneurysm typically show defining signs and necessitate medical attention.

The warning signs of an aneurysm tends to vary depending if it has ruptured or not. The signs of an unruptured aneurysm include:

  • Dizziness
  • Headache or aching sensation behind or above the eye that can be minor or severe
  • Seizures
  • Visual deficits
  • Double or blurry vision

A doctor should be seen right away if any of these signs are present.

The signs of a ruptured aneurysm include the following:

  • Stiff neck
  • Abrupt, intense headache
  • Drooping eyelid
  • Double or blurred vision
  • Light sensitivity
  • Nausea or vomiting
  • Difficulty speaking or changes in the mental state and awareness
  • Difficulty walking
  • Seizures
  • Loss of consciousness


The treatment for a brain aneurysm is based on the site, size and seriousness of the aneurysm as well as whether it has ruptured or leaking. Generally, pain medications are given to soothe the headaches and eye pain.

In case the aneurysm is accessible, surgery can fix or cut off the flow of blood to the aneurysm. This helps in preventing further growth or rupture.

Various lifestyle changes can also help in managing a brain aneurysm such as:

  • Cessation of smoking
  • Diet that includes vegetables, fruits, lean meat, whole grains and low-fat dairy products
  • Regular exercise
  • Proper control of high cholesterol or high blood pressure
