Imagine if the key to reversing rheumatoid arthritis and restoring balance to your body wasn’t found in a pill bottle, but in a single nerve running from your brain through your body. In this episode of Passion Struck, John R. Miles sits down with Dr. Kevin Tracey — pioneering neurosurgeon, scientist, and author of The Great Nerve: The New Science of the Vagus Nerve and How to Harness Its Healing Reflexes — to uncover the groundbreaking science of vagus nerve stimulation and its life-changing potential for autoimmune diseases.
Dr. Tracey reveals how targeted electrical impulses to this hidden communication superhighway can calm inflammation, improve symptoms, and offer a drug-free alternative for patients with RA and beyond. Together, they explore the discoveries, patient stories, and future possibilities that could redefine how we approach chronic illness and healing.

Healing Rheumatoid Arthritis Through the Power of the Vagus Nerve | Dr. Kevin Tracey
In this groundbreaking conversation, Dr. Kevin Tracey reveals how decades of research into the vagus nerve have led to a revolutionary approach to treating rheumatoid arthritis — one that doesn’t rely on pharmaceuticals. As a leader in neuroimmunology and a pioneer of bioelectronic medicine, Dr. Tracey explains how this “hidden superhighway” between the brain and body can be stimulated to reduce inflammation and restore balance to the immune system.
He shares the journey from unexpected laboratory findings to the recent FDA approval of the SetPoint Medical device, an implantable technology now offering life-changing results to patients. The discussion also explores the broader implications for autoimmune diseases, mental health conditions, and the future of healthcare focused on activating the body’s innate healing systems.
In This Episode You’ll Learn:
- Discover how the vagus nerve acts as the critical communication link between your brain and immune system.
- Learn why stimulating specific vagus nerve fibers can dramatically reduce inflammation without drugs.
- Hear real patient stories of transformation after receiving vagus nerve stimulation therapy.
- Understand the science behind the SetPoint Medical device and its landmark FDA approval for rheumatoid arthritis.
- Explore the potential of bioelectronic medicine to treat a range of autoimmune and inflammatory conditions.
- Gain insight into why this approach could redefine chronic illness care in the decades to come.
WHY IS THIS EPISODE A MUST-LISTEN?
This episode offers an eye-opening look at a medical breakthrough with the power to change millions of lives. If you or someone you love is struggling with rheumatoid arthritis or another autoimmune condition, you’ll gain a rare insider’s view of how cutting-edge science is shifting the treatment paradigm. Dr. Tracey’s explanations bridge complex neurophysiology with real-world impact, leaving you with hope, clarity, and a deeper understanding of how your body’s own systems can be harnessed to heal.

Vagus Nerve Stimulation: A New Hope for Rheumatoid Arthritis Patients
Rheumatoid arthritis (RA) is an autoimmune disease that affects an estimated 1.5 million Americans, causing painful swelling, stiffness, and progressive joint damage. Traditional treatments — biologics and JAK inhibitors — work well for some but fail to bring relief to nearly half of patients. Even when effective, these drugs can carry serious risks, including infections, sepsis, and certain cancers, due to their immunosuppressive nature.
In this episode, Dr. Kevin Tracey shares how targeted vagus nerve stimulation is changing that equation. Backed by over 27 years of research, his team’s work led to the SetPoint Medical device, an FDA-approved implant about the size of a multivitamin that delivers gentle electrical impulses to the vagus nerve. This stimulation triggers the body’s own “inflammatory reflex,” reducing cytokine production and shifting immune cells from an aggressive, tissue-damaging state to one that repairs and protects.
Early results are nothing short of remarkable — in the latest trial, 75% of patients were able to use the device as their primary therapy after one year, eliminating or greatly reducing their dependence on powerful drugs. For RA sufferers who have run out of options, this isn’t just another treatment — it’s a new lease on life.
The Vagus Nerve and the Future of Healing: Why Slow, Steady Progress Matters
The discoveries behind The Great Nerve: The New Science of the Vagus Nerve and How to Harness Its Healing Reflexes don’t just apply to rheumatoid arthritis. As Dr. Tracey explains, the same pathways that calm inflammation in the joints could one day be applied to a wide spectrum of conditions — from Crohn’s disease and multiple sclerosis to PTSD, depression, and even long COVID. The vagus nerve’s ability to influence the immune system, brain function, and organ health positions it as one of the most promising frontiers in medicine.
Yet, Dr. Tracey is quick to caution against rushing headlong into every new possibility. Medicine has a conservative side for good reason: not every exciting lab result will hold up in human trials, and patient safety demands that devices and therapies be proven reliable over time. In other words, we don’t want doctors chasing “shiny objects” — untested ideas that might distract from what actually works.
This careful, methodical approach is what allowed vagus nerve stimulation to move from an unexpected lab discovery to a rigorously tested, FDA-approved therapy. As The Great Nerve makes clear, real breakthroughs aren’t just about innovation — they’re about persistence, collaboration, and the discipline to ensure that new treatments genuinely improve lives. It’s this balance between bold vision and scientific rigor that could ultimately make the vagus nerve one of the most transformative tools for humanity’s health.
