Warning signs of a ruptured aneurysm include a sudden, severe headache often described as ‘the worst headache of my life,’ nausea, vomiting, neck stiffness, blurred vision, confusion, or loss of consciousness. Some patients may experience warning leaks — minor headaches or visual changes — before a major rupture.

Anyone with these symptoms should call 911 immediately. Early treatment at a specialized center like ABS’s Neurovascular Care program can save lives.
