The Psychophysiologic Disorders Association (PPDA), founded in 2009 and incorporated in 2011, is a 501(c)(3) health education non-profit dedicated to advancing the diagnosis and treatment of stress-induced medical conditions. Psychophysiologic Disorders (PPD) affect hundreds of millions of people annually, and about one third of all patient visits to primary care medical professional are PPD-related.

We are a team of clinicians, researchers and patient advocates passionate about reducing suffering in millions of people by educating medical and mental health practitioners as well as the public about PPD. We also support clinical pain and neuroscience research.

Educating health professionals around the world is necessary to increase the number of clinicians and therapists who can diagnose and treat PPD, but education is also a key component of the treatment process for patients. By learning about PPD and understanding what does and, more importantly, what does NOT cause their symptoms, patients are able to reverse the neural pathways that cause their pain and/or other chronic symptoms.

Our treatment approach is demonstrably safer, more affordable, and more effective than the usual (outdated) treatments recommended for chronic pain and medically unexplained symptoms.

With our focus on uncovering sources of stress, trauma and unrecognized emotion, patients are able to relieve and even CURE their symptoms without surgery, physical therapy, medication, or expensive alternative treatments.

Thus, our work is a vital step toward ending the chronic pain epidemic and opioid crisis.

clinical Research

Two PPDA Co-Founders - Howard Schubiner, MD, and Alan Gordon, LCSW - led a 3-arm randomized controlled trial on the efficacy of the mind-body treatment approach for patients with chronic back pain. The study took place at the University of Colorado-Boulder, along with Tor Wager, PhD, and Yoni Ashar, PhD candidate. The study will be published in early 2020 and a documentary about the study, PAIN BRAIN, is expected to release around the same time.

online Course for health professionals & Patients

We created a continuing education online course series for health professionals who want to learn how to better diagnose and treat mind-body disorders. Led by David Clarke, MD (PPDA President) and Jessica Shahinian (Executive Director), the course utilizes multiple real-world case studies to challenge participants to conduct a stress evaluation, treat the patient on the basis of empathy, and be able to eliminate (not just manage) chronic pain and medically unexplained symptoms! The course series is engaging and easy to understand, making it a valuable recovery resource for patients. Enroll Now!


ppd text book

Psychophysiologic Disorders: An Interprofessional Approach is a new textbook for healthcare professionals with planned publication in 2019.  The authors represent a wide range of training and experience including Family Medicine, Gastroenterology, Internal Medicine, Movement Therapy, Physiotherapy, Psychiatry, Psychoanalysis, Psychology, Sports Medicine and the perspective of a patient.  They also represent Australia, Canada, Ireland, the United Kingdom and six of the United States.  Chapters will focus on the neurophysiology, clinical assessment, diagnosis and treatment of common presentations of PPD including medically unexplained symptoms and chronic functional syndromes. Significant effort is being made to limit specialty-specific jargon so that a range of clinicians (and even the lay public) can take advantage of the authors' decades of experience.


THOUSAND Dollars Raised

We have raised over $300,000 to help achieve our mission of advancing the diagnosis and treatment of stress-induced medical conditions.
