Full Answer

Around 50 to 80 percent of brain aneurysms never rupture over the course of a person's life, as confirmed by Brain Aneurysm Foundation. Most aneurysms are less than an inch thick, but patients with larger aneurysms, known as giant aneurysms, are at a much higher risk. Of the patients who survive a ruptured brain aneurysm, approximately 66 percent experience permanent neurological damage. Among patients who experience an aneurysmal subarachnoid hemorrhage, around 15 percent pass away before getting to the hospital with most deaths occurring due to irreparable brain damage from the initial bleeding. Women are more likely to experience a brain aneurysm than men, and brain aneurysms are most common in individuals between the ages of 35 to 60.

Approximately 80 percent of individuals with aneurysms have very small aneurysms, and these patients have a very good prognosis, as stated by eMedicineHealth. As of 2015, an estimated 6 million people in the United States have unruptured aneurysms, and approximately 10 to 15 percent of this population develops more than one aneurysm.
