An aneurysm occurs when a blood vessel wall weakens and bulges outward, carrying the risk of rupture, severe internal bleeding, and death. The condition can develop silently — but in many cases, early warning signs do appear. Recognizing them promptly can make the difference between timely treatment and a life-threatening emergency.
The hallmark alert: a headache unlike any other
The most widely recognized early warning sign of a brain aneurysm is a sudden, extremely intense headache — commonly described as the worst headache of your life. It arrives abruptly and at a severity far beyond any ordinary migraine or tension headache.
