Know The Facts

  • It is estimated that between 2-5% of the U.S. population have a Brain Aneurysm; that's the equivalent of between 6 million and 15 million people in the United States that have an unruptured Brain Aneurysm
  • At least 1 out of every 50 people have a Brain Aneurysm
  • There are an estimated 40,000 Brain Aneurysm ruptures each year.  Of the aneurysm ruptures, almost 50% die within days; of the 50% of survivors, one-third will die within months as a result of complications, one-third will survive but with major neurological deficits, and about one-third will survive and be able to return to a way of life similar to that prior to their rupture.
  • 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. The median age when a Brain Aneurysm occurs is 50 years old and there are generally no warning signs in many instances. Most aneurysms develop after the age of 40.
  • Women and African Americans are almost 50% more likely to develop a Brain Aneurysm
  • Most aneurysms are small, about 1/8 inch to nearly one inch, and an estimated 50 to 80 percent of all aneurysms do not rupture during the course of a person’s lifetime. Aneurysms larger than one inch are referred to as “giant” aneurysms and can pose a particularly high risk and can be difficult to treat.
  • 10 – 15% of patients diagnosed with a brain aneurysm will harbor more than one aneurysm
