Aneurysm is an abnormal, bulging area on the wall of the brain artery resulting in a weak, thin wall that can burst and cause bleeding into tissues of the brain.

Common Symptoms:

  • Unruptured brain aneurysm:
    • Dilated pupils
    • Double vision
    • Localized headaches
  • Ruptured brain aneurysm warning signs:
    • Localized headaches
    • Nausea & vomiting
    • Blurred or double vision
    • Sensitivity to light
    • Loss of sensation
    • Loss of consciousness

Unruptured aneurysms may or may not have symptoms. Several deciding factors are taken into consideration before determining the course of treatment such as: the risk that the aneurysm will rupture, size and location of the aneurysm, and health of the patient, and the family history.
