ANEURYSM SYMPTOMS

WARNING SIGNS & SYMPTOMS

Ruptured brain aneurysms usually cause bleeding into the space around the brain, called a subarachnoid hemorrhage, which can cause sudden symptoms. If you experience any of the following symptoms of a ruptured aneurysm, CALL 911. It is important to understand that not all of these symptoms may be present; the top few listed below are the most common.

DO NOT have a family member/friend take you in a private vehicle to the hospital. This is a high-stress situation that may require first responders to use lifesaving procedures in the emergency vehicle, and where time may be of the essence.

  • Sudden and severe headache, often described as “the worst headache of my life”
  • Nausea/vomiting

  • Stiff neck

  • Blurred or double vision

  • Sensitivity to light

  • Seizure

  • Drooping eyelid

  • A dilated pupil

  • Pain above and behind the eye

  • Loss of consciousness

  • Confusion

  • Weakness and/or numbness

Unruptured brain aneurysms usually have no symptoms. Typically, these aneurysms are small. Many unruptured aneurysms are found incidentally when tests are being done to screen for other conditions. Rarely, unruptured aneurysms may become large and press on nerves in the brain, causing symptoms. If you experience these symptoms, seek prompt medical attention. Unruptured aneurysms rarely cause chronic headaches.

  • Blurred or double vision
  • A drooping eyelid

  • A dilated pupil

  • Pain above and behind one eye

  • Weakness and/or numbness
