6. Seizures
A first-time seizure in an adult with no epilepsy history is alarming. It can occur when an aneurysm disrupts normal brain electrical activity. Research shows seizures appear in up to 20% of rupture cases, making this one symptom that always warrants an emergency evaluation.
7. Drooping Eyelid or Facial Weakness
One eyelid may suddenly droop, or part of your face might feel numb or weak. This happens when the aneurysm compresses nearby cranial nerves. It can look like a mini-stroke, which is exactly why you need to act fast.
8. Loss of Consciousness
Fainting or suddenly blacking out is an extreme warning. It often means significant bleeding or pressure buildup inside the skull. Even brief episodes require immediate medical help because they signal the brain is under serious stress.
9. Trouble Speaking or Understanding Speech
Slurred words, confusion, or difficulty following conversations can emerge suddenly. These language problems stem from the aneurysm affecting areas responsible for communication. It’s a classic neurological red flag that mimics stroke symptoms.
10. Difficulty Walking or Dizziness
Sudden balance problems, unsteadiness, or vertigo can make walking feel impossible. The aneurysm may be interfering with brain regions that control coordination. This symptom often appears alongside dizziness that doesn’t go away with rest.
11. Pain Behind or Around the Eye
A localized, persistent ache behind one eye or around the socket is common with unruptured aneurysms in that area. It feels different from sinus pain and may come with vision changes. Many people mistake it for eye strain until other signs appear.
12. Personality or Behavioral Changes
This is the often-overlooked clue I promised earlier. Growing aneurysms can subtly alter mood, cause unexplained irritability, confusion, or even personality shifts. Because these changes develop gradually, families sometimes attribute them to stress or aging instead of seeking help right away.
But that’s not the whole picture. Here’s something important: not every headache means an aneurysm, yet any sudden combination of these signs deserves urgent care.
Risk Factors That Increase Your Chances
Certain factors can make brain aneurysms more likely. Knowing them helps you stay vigilant:
- High blood pressure that isn’t well controlled
- Smoking or a history of tobacco use
- Family history of aneurysms or related conditions
- Being female (risk rises after age 40)
- Certain genetic disorders or connective tissue conditions
- Heavy alcohol consumption or illicit drug use
Research consistently links these factors to higher aneurysm formation and rupture rates.
