Teen's headache reveals alarming health risk for family: "Saving people's lives"

Key Points:

• On Father's Day 2025, 18-year-old Caroline McCaffrey experienced a sudden, severe headache and vomiting during an evening run, later diagnosed as a ruptured brain aneurysm after initial misdiagnosis as a migraine at a hospital.
• Caroline was treated at the University of Maryland Medical Center, where doctors found two brain aneurysms, one ruptured causing an aneurysmal subarachnoid hemorrhage; she underwent surgeries and intensive care before being released after three weeks.
• A family medical history revealed a genetic predisposition to aneurysms, leading to testing of relatives; Caroline's mother and sister-in-law were also found to have aneurysms and received treatment.
• Both Caroline and her mother have fully recovered but will require lifelong monitoring; Caroline is now a college junior, running competitively, participating in NIH studies on brain repair, and considering a nursing career inspired by her experience.
• Caroline is actively involved in research and advocacy for aneurysm survivors, aiming to contribute to medical understanding and support for young patients through potential future charitable work.
