Worldwide, cerebral aneurysms occur in 3.2% of the global population, with the mean age of presentation being 50 years. Scientists estimate that over 6 million Americans have an unruptured aneurysm in the brain, and about 30,000 of them rupture each year. In 40 of each hundred ruptures, the patient dies.
Brain aneurysms are more common in females by about 60% overall, and more especially in the postmenopausal age group, where the risk is more than twice as high.
