Symptoms generally fall into two categories:
- Unruptured aneurysm: Often causes no symptoms but may produce mild symptoms if it presses on nearby nerves or brain tissue.
- Ruptured aneurysm: Usually causes sudden, severe symptoms that require emergency medical care.
Possible Signs of an Unruptured Brain Aneurysm
1. Persistent Localized Headache
A headache that consistently occurs in one specific area—particularly behind or above one eye—and differs from your usual headaches may warrant medical evaluation.
2. Vision Changes
An enlarging aneurysm may press on nerves that control vision, potentially causing:
- Blurred vision
- Double vision
- A dilated pupil
- A drooping eyelid
- Reduced peripheral vision
3. Pain Around or Behind the Eye
A persistent ache around one eye that does not improve may occur if nearby nerves are affected.
4. Facial Numbness or Weakness
Pressure on certain nerves may lead to numbness, tingling, or weakness affecting one side of the face.
5. Difficulty Speaking
Some people may notice slurred speech or difficulty finding words, although these symptoms can have many different causes.
