Brain Aneurysms

About Your Care and Condition

When you hear “brain aneurysm,” it can be scary, but did you know that 50 to 80 percent of brain aneurysms never rupture? Let's work to keep you in that group. We have the area’s largest team of neurologists.

A brain aneurysm is a weakened area in the artery wall that supplies blood to the brain, creating a balloon-like bulge. Most are smaller than 10 millimeters and develop after age 40. If they do rupture, brain aneurysms can become life-threatening. A ruptured aneurysm may cause a seizure or dizziness. There are also procedures that can be performed to avoid or treat ruptures.
