While a brain aneurysm may not cause problems on its own, if it leaks or bursts, the result can be a life-threatening stroke. By knowing the symptoms of an aneurysm, patients can see a doctor before that happens.
As the Mayo Clinic’s website puts it, a brain aneurysm is a bulge or ballooning section in a blood vessel in the brain. It often resembles a berry hanging on a stem. Symptoms of an unruptured aneurysm include pain above and behind one eye, a dilated pupil, double vision, numbness or paralysis on one side of the face, and a drooping eyelid.
