Why doctors refer their patients to the DNRS Program

About 10% of Covid-19 patients develop long haul symptoms, or Post-Acute Covid-19 disease (PACS). They suffer from various symptoms that can include high heart frequency, breathlessness, autonomic dysfunction with a high proportion of patients fulfilling criteria for postural orthostatic tachycardia syndrome (POTS), mental fatigue, muscle and joint pain, headache, nausea, cognitive impairment and memory problems, loss of smell and taste, sensitivity to light and sound, fluid retention and weight gain, gastrointestinal symptoms, high body temperature, hormonal disturbances, histamine intolerance and signs of mast cell activation syndrome (MCAS). Many of these symptoms may be explained by a limbic system impairment. So far, we have observed great to astonishing full recovery from severe long Covid / post-acute Covid-19 disease (PACS)/autonomic dysfunction/postural orthostatic tachycardia syndrome,(POTS), chronic inflammatory response syndrome (CIRS) and hyper-reactivity to food, mold and chemicals, in many patients undergoing DNRS training. As we only have limited symptomatic treatment to offer these patients within regular medical care, I recommend patients to explore DNRS training to support their recovery from these conditions, while we await scientific studies validating the effect of DNRS training in controlled studies, and explore mechanistic explanations to how DNRS training can potentially cure patients from PACS, POTS and CIRS.

“I had a chronic stress related condition, and it was affecting many systems of my body. I knew the breadth of traditional and Integrative medicine, what they could (some wonderful things) and could not offer. The science behind DNRS made sense. The pieces of the puzzle came together as I sat there. And, as they say, the rest is history! During my time undertaking the DNRS program, I have tried to keep my “medical hat” off as much as is humanly possible after more than 30 years as a practising doctor. I had lots of medical knowledge of course, but zero knowledge on practical neuroplasticity or brain retraining.”

"The brain is not immune to the damaging effects of toxic mold. I recommend that anyone with CIRS (Chronic Inflammatory Response Syndrome / Mold Illness) or any other environmental illness take this program. DNRS resets limbic system function and reduces (or eliminates completely) mold hypersensitivity. Many of my patients have had tremendous results!"

Dr. Margaret Christensen


"I have referred many (hundreds) of my most chemically sensitive patients and those who suffer from complex chronic illnesses to the DNRS program with results that range from great to fantastic. It is becoming increasingly clear to those of us who work in this field that "rebooting" the limbic system is a critical component for our patients and many cannot make progress until they pursue this avenue of treatment."

Dr. Neil Nathan

"The DNRS program teaches us how to access our “rest and digest” physiology— the parasympathetic nervous system— which promotes vitality and diminishes chronic inflammation. This practice has the potential... to help persons with any type of chronic inflammatory state (most, if not all, chronic diseases... autoimmune disorders, multiple chemical sensitivity, and emotional imbalances).

Dr. Cynthia Li


“I am a naturopathic doctor treating chronic complex disease, specifically Lyme disease, mold, and hypersensitivities for over ten years. Over the last couple of years, many patients with mold and environmental sensitivities have [implemented] the Dynamic Neural Retraining System... and every single person has come back transformed, with clinical results nothing short of miraculous.”

Dr. Mischa Grieder, N.D.


“I’ve been treating patients with complex, chronic illness for over a decade. Addressing limbic system function is the missing key for many patients... I’ve witnessed dramatic improvements and even complete recoveries with DNRS. In many cases, these patients have been sick for years... I’ve become a huge believer in DNRS and often recommend it to my patients.”

Chris Kresser, M.S., L.Ac


"I have referred many patients with [extreme sensitivities] when there is willingness to engage and ‘work the program.’ Some patients are able to do the DNRS program on their own at home (with the instructional video program), while others benefit from additional coaching with a certified DNRS Coach. I am deeply appreciative of the contributions that Annie Hopper has made to healing.”

Patrick Hanaway, MD


“As a physician specializing in treating patients with chronic Lyme Disease, Mold Illness and Mast Cell Activation Syndrome... DNRS is a powerful tool that has helped many of my patients immensely. It addresses the critical limbic component that we as physicians are only beginning to recognize. Having gone through the program myself... the effort and time involved is well worth it.”

Dr. Raj Patel

"As a medical doctor, I have found that most of my patients are staying stuck in an autonomic setting of threat and stress as a result of [toxin] exposures. In addition to my efforts... I have found that these individuals frequently respond very quickly to [DNRS] therapeutic modalities to assist them in migrating their autonomic threat state back to a parasympathetic state of calmness and tranquility."

Wally Taylor MD


“I have referred several patients to DNRS... I heard Annie Hopper speak at the TIFM conference in Seattle in February and was very impressed with the work that she is doing, and immediately recognized that I have several patients in my practice that would benefit from the program. I also have a previous patient that has fully recovered from doing the program. Keep up the good work.”

Dr. Mielke

"I've referred well over 100 of my chemically sensitive patients to the Dynamic Neural Retraining System and the results have been fantastic.  Healing the limbic response is a critical part of recovery from multiple chemical sensitivity as well as many other conditions."

Dr. William Weirs

"As a Naturopathic Doctor treating Lyme and other environmentally acquired illnesses, I came across DNRS a few years ago. There is a portion of this population that doesn’t get better, despite doing all the right things— the right lifestyle, the right medications and the right diet. DNRS takes these patients to a new level... their brains understand that they can stop fighting and start healing."

Dr. Nicole Meier

“At the California Center for Functional Medicine, we take a whole-person approach to recovery. Healing is most robust when the physical, psychological, and spiritual aspects are addressed simultaneously. DNRS has been extremely helpful for many of our patients and I recommend it wholeheartedly.”

Dr. Sunjya Schweig

“I work with chronically ill patients... and it is clear to me how crucial resetting the limbic system is for true healing to occur. I have seen some really dramatic results, especially in patients who have done a lot of treatment already and may have had some improvement but just can’t seem to get over the hump. I really feel like this is a missing piece in the treatment of chronic illness.”

Nicola McFadzean Ducharme, N.D.

“I have recommended the DNRS program to over 300 patients with incredible treatment success. It is very clear that doctors need to recognize and treat the limbic injury [before attempting other treatments]... clearly, pursuing the DNRS program is an absolute first order of business. With DNRS, I have innate confidence that every patient has the ability to get well and stay well.”

Dr. Marie Matheson

“For many of my patients, DNRS has been the step needed to complete their healing cycle. All of my patients [who implemented the DNRS program] stated that is was well worth it. This is often the last piece needed in healing mold toxicity, multiple chemical sensitivity, and many other chronic, reactive issues. I am truly appreciative of Annie and her team in helping my patients.”
