  • Almost 500,000 deaths worldwide each year are due to a ruptured brain aneurysm.


  • An estimated 1 in 50 people have an unruptured brain aneurysm.

  • About 30,000 people in the United States suffer a brain aneurysm rupture each year.

  • A brain aneurysm ruptures every 18 minutes and when this happens they are fatal in about 40% of cases​.

  • Accurate early diagnosis of a ruptured aneurysm is critical,  as the initial hemorrhage may be fatal or result in devastating neurological outcomes. About two-thirds of those who survive a rupture suffer from some permanent neurological impairment.

  • Approximately 15% of people with a ruptured aneurysm die before reaching the hospital .  Most of the deaths are due to rapid and massive brain injury from the initial bleeding. 

  • Despite the widespread availability of brain imaging that can detect a ruptured brain aneurysm, misdiagnosis or delays in diagnosis occur in up to one quarter of the patients when initially seeking medical attention. In three out of four cases, misdiagnosis results from a failure to do a scan. 

  • People who suffer from a ruptured brain aneurysm have a 40% better chance of survival when treated at a high volume hospital, one that treats more than 35 cases per year, compared to those admitted to a low volume center that treat fewer cases a year, according to a new study. ​​

  • An estimated 50-80% of all aneurysms do not rupture during the course of a person's lifetime.  However, among patients evaluated in an emergency room for headaches, approximately one in 100 has a ruptured aneurysm according to one study.  This is why in my opinion it is very important to demand a scan if you are having ongoing headaches or other symptoms.
