Symptoms

Most aneurysms do not cause any symptoms. However, a growing aneurysm might push against blood vessels or other structures and cause headaches, double vision, or pain around the eyes.

If the aneurysm bleeds, people often suffer from a sudden and severe headache, one they might call the “worst they ever experienced,” as well as neck pain and stiffness. They might also develop typical stroke symptoms.

Common signs and symptoms of a ruptured aneurysm also include:

  • Blurred or double vision
  • Confusion
  • Drooping eyelid
  • Loss of consciousness
  • Nausea and vomiting
  • Seizure
  • Sensitivity to light
  • Stiff neck
  • Sudden numbness of the face, arm, or leg, especially on one side of the body
