🔬 The science: Small aneurysms rarely press on nerves. Larger ones may cause localized symptoms, but there’s no reliable “warning pain” before rupture. This is why awareness—not waiting for symptoms—is key.
❌ Myth #3: “If You Have an Aneurysm, It Will Definitely Rupture”
✅ Fact: Most aneurysms never rupture. In fact, many people live their entire lives with an unruptured aneurysm and never know it’s there.
🔬 The science: Rupture risk depends on size, location, shape, and individual factors like blood pressure and smoking history. Small, stable aneurysms (<7mm) often carry a very low annual rupture risk (<1%).
❌ Myth #4: “Headaches Mean You Have an Aneurysm”
✅ Fact: The vast majority of headaches are not caused by aneurysms. Tension headaches, migraines, and sinus issues are far more common culprits.
🔬 The science: Aneurysm-related headaches are distinct: sudden, severe, “worst ever,” and often accompanied by other neurological symptoms (vision changes, neck stiffness, confusion). If your headache fits this pattern—seek care immediately.
