The symptoms of a brain aneurysm vary depending on whether it has ruptured or not. In many cases, an unruptured aneurysm causes no noticeable signs and is often discovered incidentally during medical scans. However, if it grows large enough to press on brain tissues or nerves, it may cause persistent headaches, blurred or double vision, pain above or behind the eye, a drooping eyelid, or numbness on one side of the face. When a brain aneurysm ruptures, it becomes a medical emergency. The most common symptom is a sudden, extremely severe headache, often described as the “worst headache of one’s life.” Other warning signs may include nausea, vomiting, stiff neck, light sensitivity, confusion, seizures, or loss of consciousness. Immediate medical attention is vital, as a ruptured aneurysm can result in brain damage, stroke, or even death.
