An aneurysm is a balloon-like bulge in an artery, which is a blood vessel that carries oxygen-filled blood throughout the body, according to the National Institutes of Health (NIH).

A balloon-like bulge associated with any artery in the brain would be classified as a brain aneurysm. Most brain aneurysms have no symptoms until they are large, leak blood, or burst.

Brain aneurysm symptoms, according to the NIH, could include:

  • Dilated pupil
  • Double vision or other vision issues
  • Droopy eyelid
  • Numbness or weakness on one side of the face or body
  • Pain above or behind the eye

Talk to your doctor for more information about aneurysms.
