It's the most impactful revolution in mental health since the introduction of Prozac in 1986: ketamine-assisted psychotherapy. In this book, bestselling author Dr Mike Dow and Field Trip co-founder and executive chairman Ronan Levy provide a broad overview of where ketamine-assisted psychotherapy (KAP) came from, how it works, who it works for and what to expect. They outline key moments in scientific history that have paved the way for KAP's future and explore its specific protocol for both practitioners and patients. This book contains hope for those diagnosed with treatment-resistant depression, plagued by trauma and frozen by fears. Ketamine has been described as being possibly 'the most important breakthrough in antidepressant treatment in decades'. When combined with psychotherapy it has the potential to treat depression, anxiety, PTSD and other debilitating mental illnesses. The Ketamine Breakthrough changes lives.
