Why Awareness Matters
Aneurysms are dangerous not only because they can rupture, but because they are often silent until it is too late.
Understanding the facts can help people:
- Recognize warning signs early
- Identify personal risk factors
- Seek timely medical evaluation
Even before rupture—or at the moment it begins—the body may show warning signs.
Possible early (unruptured) aneurysm signs:
- Pain behind or above one eye
- Dilated pupil
- Blurred or double vision
- Drooping eyelid
- Numbness or weakness on one side of the face
These symptoms may occur when the aneurysm presses on nearby nerves.
Emergency signs of rupture:
- Sudden, extremely severe headache (“worst ever”)
- Nausea and vomiting
- Stiff neck
- Sensitivity to light
- Confusion or loss of consciousness
- Seizures
This is a medical emergency. Seek immediate emergency services.
