Brain Aneurysm Symptoms

If a brain aneurysm presses on nerves in your brain, it can cause:

  • a droopy eyelid
  • double vision or other changes in vision
  • pain above or behind the eye
  • a dilated pupil
  • numbness or weakness on one side of the face or body

If a brain aneurysm leaks blood or ruptures, it can cause specific signs or symptoms:

  • sudden onset of headache ("the worse headache of my life")
  • sudden loss of decreased consciousness and alertness
  • numbness or weakness on one side of the face or body
  • mood and personality changes, including confusion and irritability
  • nausea and vomiting
  • neck pain and stiffness
  • photophobia (lights bothers or hurts the eyes)
  • double vision or other changes in vision
  • eyelid drooping
  • seizures

Before a rupture, a patient may experience any of these brain aneurysm symptoms . Others produce no symptoms at all and their onset is without warning. Rupture of a brain aneurysm is extremely dangerous and medical attention should be sought immediately.

If it does become symptomatic, there are tests that can be performed to find and diagnose a brain aneurysm.
