Brain Aneurysm & Hemorrhage
Brain Aneurysm Prevalence
It is estimated that one in every 50 people in the United States suffers from an unruptured brain aneurysm, while an average of 30,000 people suffering from a rupture annually. Ruptured brain aneurysms are fatal in about 40 percent of cases. Of those who survive, about 66 percent suffer some permanent neurological deficit.
Genetic Factors Could Help Doctors Identify People at Risk of Developing a Brain Aneurysm
Even though most brain aneurysms cause no symptoms and may only be discovered during tests for another, usually unrelated condition, researchers have discovered genetic factors that could help doctors identify people who are at the greatest risk for developing a brain aneurysm.
Some studies show that first-degree relatives of people who suffered aneurysmal hemorrhage are more likely to have aneurysms themselves. These studies also reported that such immediate family members were four times more likely to have aneurysms than the general population
