Long before "brain retraining" became a recognised term, Dr John Eaton had already spent years developing the approach behind it. He founded Reverse Therapy in 2002 - a method built on the same core insight now driving today's most talked-about recovery programmes for Chronic Fatigue Syndrome, Fibromyalgia and Long Covid: that these conditions often involve a nervous system and limbic system caught in a persistent, self-reinforcing state of threat and hypervigilance, and that recovery becomes possible once that pattern is interrupted.
This book, fully updated, explains that process in plain language. Dr Eaton draws on neuroscience, emotional intelligence and mind-body medicine to describe how chronic stress can lock the brain into a cycle that produces and maintains physical symptoms - and lays out a complete, step-by-step protocol for reversing it.
Where many current brain-retraining and neuroplasticity programmes trace their roots back to this original work, Reverse Therapy remains distinctive in one important respect: it was developed and is still delivered by a single practising psychotherapist with over three decades of direct clinical experience, not a subscription platform or app.
Inside, you'll find:A clear account of how the limbic system and nervous system sustain conditions like Chronic Fatigue Syndrome, Fibromyalgia, IBS, and other medically unexplained symptoms
The theory and origins of Reverse Therapy, and how it evolved into a full clinical protocol
A complete self-guided version of the process, usable independently or alongside one-to-one sessions
Insight into why some recovery attempts fail, and what a sustained shift in the brain-body relationship actually requires

Whether you've come across newer brain-retraining programmes and want to understand where the approach began, or you're searching for a mind-body explanation for symptoms that medicine hasn't been able to resolve, this book offers a grounded, experience-tested route back to health - from the psychotherapist who was working in this field before it had a name.
