Brain Aneurysm Basics That Can Save your life.
What Is A Brain Aneurysm?
A brain aneurysm is a weak bulging spot on the wall of a brain artery, very much like a thin balloon or weak spot on an inner tube.
Brain Aneurysm Statistics
- An estimated 6 million people in the United States have an unruptured brain aneurysm, or 1 in 50 people.
- The annual rate of rupture is approximately 8 per 100,000 people or about 30,000 people in the United States.
- There is a brain aneurysm rupturing every 18 minutes.
- There are almost 500,000 deaths worldwide each year caused by brain aneurysms and half the victims are younger than 50.
- About 40% of all people who have a ruptured brain aneurysm will die as a result. Of those who survive, about 66% will suffer some permanent deficit.
- 4 out of 7 people who recover from a ruptured brain aneurysm will have disabilities.
- Brain aneurysms are most prevalent in people ages 35 – 60, but can occur in children as well.
- Women, more than men, suffer from brain aneurysms at a ratio of 3:2.
- Ruptured brain aneurysms account for 3 – 5% of all new strokes.
- Localized headache
- Dilated pupil
- Blurred or double vision
- Pain above and behind the eye
- Weakness and numbness
- Difficulty speaking
Localized or diffuse headache associated with one

- Sudden change in mental status or awareness
- Sudden trouble walking or dizziness

- Sensitivity to light (photophobia)
- Drooping eyelid
Risk Factors that doctors and researchers believe contribute to the formation of brain aneurysms:
- High blood pressure or hypertension
- Congenital resulting from inborn abnormality in artery wall
- 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 disorders: Ehlers-Danlos Syndrome, Polycystic Kidney Disease, Marfan's Syndrome, Fibromuscular Dysplasia(FMD)
- Presence of an arteriovenous malformation (AVM)
- Drug use, particularly cocaine
- Traumatic head injury
