  • Localized Headache

  • Pain above or behind the eye

  • Blurred vision or double vision

  • Drooping of eyelid

  • Dilated pupil

  • Face Numbness 

  • Stroke symptoms: BEFAST (The blood clot could form inside the big aneurysm and can travel to the artery of the brain and causes a stroke)









If an aneurysm ruptures, it causes the bleeding into the space around the surface of the brain. This condition called a subarachnoid hemorrhage (SAH). This is an EMERGENCY condition. Call 911 immediately. About 15% of patients with SAH passed away before reaching the hospital.
