In this two-part episode of The Medical Detectives, Katie shares the story of her husband Steve’s long and heartbreaking journey toward a diagnosis. Katie takes us back to the early days of their relationship, painting a vivid picture of Steve as a strong, vibrant man devoted to protecting North Carolina’s water systems and to the people he loved. But everything began to change when subtle symptoms, like handwriting issues, dizziness, and vision problems, signaled the start of a confusing and frustrating diagnostic odyssey. Over the course of a year, Katie and Steve consulted multiple specialists, endured countless misdiagnoses, and chased down false leads ranging from diabetes and spinal degeneration to Parkinson’s and stroke, all while Steve's condition rapidly declined. Through it all, Katie remained his fiercest advocate, navigating a broken system with persistence and love. This is part one of their story, a testament to resilience, the limits of medicine, and the deep cost of diagnostic delay. Part two, coming next week, takes a turn no one saw coming.
