This week on Ditch the Labcoat, Dr. Mark Bonta sits down with Dr. Diana Driscoll, an optometrist, researcher, and internationally recognized authority on the autonomic nervous system—who also happens to be one of the rare non-MDs to join the show. 

After her own sudden and life-altering health collapse, Dr. Driscoll found herself deep in the world of dysautonomia—a group of disorders affecting the autonomic nervous system, responsible for all those automatic functions in our bodies we don’t usually have to think about. Finding few answers from doctors, and confronted by a system that too often shuns “invisible illnesses,” Dr. Driscoll became her own medical detective, pioneering research into conditions like Postural Orthostatic Tachycardia Syndrome (POTS) and unlocking innovative approaches to treatment.

In this eye-opening conversation, Dr. Driscoll and Dr. Bonta tackle the complex, often misunderstood world of autonomic dysfunction, the science behind “mystery illnesses,” and the frustrating gaps in our medical knowledge. From the lived experience of being a patient who was told “it’s all in your head,” to developing new therapeutics and advocating for others, Dr. Driscoll’s story is as inspiring as it is informative.

If you’ve ever struggled with unexplained symptoms, felt dismissed by the healthcare system, or just want to understand the evolving science behind these often-invisible disorders—this episode is for you. 

Plug in for a candid, practical, and hope-filled discussion that challenges the boundaries of what medicine knows today and explores the frontier where suffering finally meets science.

Episode Highlights

1. Invisible Illness Is Real — Validation for patients with unexplained symptoms is crucial; their suffering is genuine, not imagined or "all in their head."
2. Medicine’s Knowledge Blindspots — The medical establishment often lacks answers—and even language—for complex autonomic disorders like dysautonomia and POTS.
3. Patient-Led Discovery Matters — Dr. Driscoll's personal journey from patient to researcher demonstrates the power of self-advocacy in pushing knowledge forward.
4. Autonomic System Ignorance — Most clinicians receive minimal training about the autonomic nervous system, leading to missed diagnoses and inadequate care.
5. One Size Doesn't Fit All — There is no single solution for autonomic dysfunction—treatments must be individualized to each patient’s complex presentation.
6. Beyond Symptom Management — Suppressing symptoms (e.g., racing heart) without understanding the root cause can worsen patient outcomes or miss vital clues.
7. The Inflammatory Connection — Inflammation, triggered by infections or stress, can drive autonomic dysfunction—a framework for science to pursue targeted therapies.
8. Necessity of Clinical Innovation — When guidelines and therapies don’t exist, scientific curiosity and non-traditional research can inspire new approaches and hope.
9. The Power of Lived Experience — Practitioner-patients like Dr. Driscoll bridge gaps between science, clinical care, and compassion through firsthand understanding.
10. Hope Through Education — Educating both patients and practitioners fosters progress—there’s always hope, even if answers come step by step.
