Aneurysm is the term for a bulging blood vessel in the brain. If the vessel leaks or ruptures, it can cause bleeding, which is known as a hemorrhagic stroke. Brain aneurysms on their own are common, and tend to be negligible since they don’t cause symptoms or health issues, and never rupture. However, a ruptured aneurysm is a medical emergency, and knowing the signs can prevent permanent brain damage and death.

Symptoms of a ruptured aneurysm

1. A sudden and severe headache (often described as “the worst headache of my life”)
2. Blurred or double vision
3. Confusion
4. One dilated pupil
5. One drooping eyelid
6. Fainting
7. Nausea/vomiting
8. Pain around one eye
9. Stiffness in the neck
10. Sensitivity to light
11. Seizures
12. Weakness and/or numbness
