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.
