A brain (cerebral) aneurysm is a weak, bulging spot in a blood vessel in the brain. Most are silent until they leak or rupture—and when they do, it’s a life-threatening emergency. But sometimes, unruptured or leaking aneurysms cause subtle warning signs that people dismiss as stress, fatigue, or migraines.
Recognizing these symptoms early can be lifesaving. If you or someone experiences any of the following—especially suddenly—seek emergency medical care immediately.
🚨 Critical Warning Signs (Especially if SUDDEN)
1. “The Worst Headache of Your Life”
- A thunderclap headache that hits within seconds to minutes—often described as being “struck by lightning” in the head.
- This may signal a rupture or “sentinel leak” (a small warning bleed).
2. Nausea or Vomiting (with Head Pain)
- Not from food or illness—but sudden and intense, paired with severe head pain.
3. Stiff Neck
- Caused by blood irritating the spinal membranes after a leak—often with headache and light sensitivity.
4. Blurred or Double Vision
