Ruptured Brain (Cerebral) Aneurysms

A brain aneurysm, also called a cerebral aneurysm, is a condition whereby there is a bulging, weak area in the wall of an artery that supplies blood to the brain. A brain aneurysm in most cases causes no symptoms and goes unnoticed. In rare cases, a brain aneurysm ruptures, leading to a subarachnoid hemorrhage, which releases blood into the skull and causes a stroke. Brain damage and even death may result, depending on the severity of the hemorrhage.

The circle of Willis, a network of blood vessels at the base of the brain, is the most common location for brain aneurysms.

Ruptured Aneurysm Symptoms

Typically a sudden and severe headache is one of the key symptoms of a ruptured aneurysm. This type of severe headache is most often described as the worst headache a person has ever experienced. The most common symptoms and signs of a ruptured aneurysm include:

  • A drooping eyelid
  • Blurred or double vision
  • Confusion
  • Loss of consciousness
  • Nausea and vomiting
  • Seizure
  • Sensitivity to light
  • Stiff neck
  • Sudden, extremely severe headache
