Learning: Dynamic Neural Retraining System (DNRS)

My Plan

Het Dynamic Neural Retraining System (DNRS) is een zelfgestuurd cursusprogramma voor mensen met chronische ziekten. Het leert een dagelijkse mentale routine, die gedurende maanden wordt geoefend en bedoeld is om wat het programma een vastgelopen dreigingsreactie in de hersenen noemt, te onderbreken. Het wordt geadverteerd voor myalgische encefalomyelitis en chronisch vermoeidheidssyndroom, multiple chemische gevoeligheid, fibromyalgie en langdurige COVID (long COVID). Bij veel van deze aandoeningen versterkt het zenuwstelsel pijn, vermoeidheid en gevoeligheid — een proces dat centrale sensibilisatie wordt genoemd. Gedragsmatige en psychologische benaderingen helpen sommige mensen. Er is geen gerandomiseerd onderzoek uitgevoerd om DNRS zelf te testen.

De dichtstbijzijnde gecontroleerde bewijskracht komt van verwante therapieën. Eén: een klein gerandomiseerd onderzoek naar amygdala-hertraining bij fibromyalgie en chronische vermoeidheid. Twee: een groter onderzoek naar een hersen-gebaseerde pijntherapie bij chronische rugpijn. De symptomen die het behandelt, zijn fysieke ziekten. De grootste zorg is marketing die suggereert dat het organische ziekte omkeert.

What It Is

The Dynamic Neural Retraining System is a self-directed course that Annie Hopper created, sold as an online video program with a workbook for people with long-running chronic illness. It is also marketed for mold illness and for food and chemical intolerances. The course runs about 14 hours of instruction, followed by a daily practice the program asks people to keep up for at least six months. The online version costs a few hundred dollars, with optional in-person and coaching add-ons that cost more.

How It Works

DNRS builds on one idea: in these conditions the limbic system, the brain's threat circuitry, stays over-activated, and DNRS holds that this over-activation sustains the symptoms.

In fibromyalgia and related conditions the spinal cord and brain amplify incoming signals, so ordinary input can register as pain, and the thresholds for fatigue, nausea, and sensitivity fall. That amplification is measured and physical. It is part of why the symptoms count as real illness.

Next is the conditioned response. The body learns associations, so a smell, food, or place that once came with feeling ill can begin to trigger symptoms on its own. This is the same learning that sits under many anxiety responses.

The third claim is the unconfirmed one: that a rehearsed daily routine, through neuroplasticity, retrains the limbic system out of the illness. The program says people recover from conditions like ME and MCS this way. Naming central sensitization and the conditioned response explains why an approach might help, though it does not make the illness psychological. A person can carry a sensitized nervous system and an organic disease at the same time.

What the Program Asks of You

Anatomy of the Practice

1The course

The person watches about fourteen hours of video and learns the model and the daily routine. The program teaches that these symptoms come from a conditioned brain response, and it makes that reframing central to the method.

2The daily practice

The person runs the routine several times a day, and whenever a symptom or stressful thought starts. They stop, step through a short sequence of movements and visualizations, and rehearse calm, positive statements. The program asks for a firm commitment, often an hour or more a day, kept up without long gaps.

3Over months

Many who finish report improvement. But the people who sustain a demanding daily practice differ from those who start it, and these illnesses rise and fall on their own. Reported improvement is not proof the practice caused it. The program describes recovery as gradual and uneven.

What the Evidence Shows

The strongest controlled test of the idea used a different program in a different condition. A randomized trial gave pain reprocessing therapy to 151 adults with chronic back pain, teaching them to treat pain as a safe brain signal. At four weeks, 66% were pain-free or nearly so, against 20% on an open-label placebo injection and 10% on usual care. Back pain differs from the fatigue and sensitivity DNRS targets. The trial shows a brain-based approach can lower chronic primary pain, but only for pain. Brain-based approaches to central sensitization are an active research area, and what is tested in chronic back pain today may reach these conditions next.

Closer to DNRS is a single-blind randomized trial that added amygdala retraining to standard care for people with fibromyalgia and chronic fatigue. Those who received it reported better physical health, energy, pain, symptom distress, and fatigue than the standard-care group. The result is fragile: of 44 people randomized, only 21 finished, and just 7 completed the retraining arm.

DNRS itself has never been tested in a controlled trial. The strongest published study of a comparable program, amygdala and insula retraining, reported that participants rated their health higher after three or more months across most conditions studied. It had no control group.

The data were self-reported from a small, self-selected sample, and the author was a paid consultant to the program. Most of the remaining support is testimonial, published by the programs themselves.

How it works

Chronische pijn en verwante aandoeningen omvatten versterking door het zenuwstelsel (centrale sensitisatie)Moderate · mixed
In plain terms

Bij aandoeningen zoals fibromyalgie zet het zenuwstelsel het volume op pijn en andere signalen hoger. De symptomen zijn lichamelijk, en deze versterking is een erkend mechanisme, niet iets wat mensen zich inbeelden.

In detail

Bij veel chronische pijn en functionele aandoeningen, waaronder fibromyalgie, versterkt het centrale zenuwstelsel pijn en andere sensorische signalen, in plaats van alleen lopende weefselschade te rapporteren, een proces dat centrale sensitisatie of nociplastische pijn wordt genoemd. Het is een erkend mechanisme en deel van waarom de symptomen lichamelijk zijn. Measured in: Adults with chronic pain conditions, synthesized in a general medical review of chronic pain. Centrale sensitisatie verklaart een deel van deze aandoeningen en maakt ze niet psychologisch of omkeerbaar door gedachten. Het is een reden waarom een benadering via het zenuwstelsel zou kunnen helpen, geen bewijs dat een bepaald programma dat doet.

Pain

Een hersengebaseerde pijntherapie liet tweederde van de chronische rugpijnpatiënten pijnvrij achter, tegenover een vijfde bij placeboModerate
In plain terms

In één studie liet een hersengebaseerde therapie die pijn herkadriseert als een vals alarm tweederde van de chronische rugpijnpatiënten pijnvrij achter, tegenover een vijfde bij een placebo. Dit is een ander programma dan DNRS, getest bij een andere aandoening.

In detail

In een gerandomiseerde studie bij 151 volwassenen met chronische rugpijn liet pijnherverweringstherapie, waarbij patiënten worden geleerd pijn te herinterpreteren als een niet-gevaarlijk hersensignaal, 66% (33 van de 50) pijnvrij of bijna pijnvrij achter na vier weken, tegenover 20% (10 van de 51) bij een open-label placebo-injectie en 10% (5 van de 50) bij gebruikelijke zorg. De gemiddelde pijn daalde naar 1.18 van de 10 bij de therapie, tegenover 2.84 bij placebo en 3.13 bij gebruikelijke zorg, en de winsten hielden aan na één jaar. Measured in: 151 adults with primary chronic back pain, 54% female, mean age 41, in a university research setting. Dit testte pijnherverweringstherapie, niet DNRS, en bij chronische rugpijn, niet de vermoeidheids- en gevoeligheidsaandoeningen die DNRS richt. Het is indirecte steun dat een hersengebaseerde benadering chronische primaire pijn kan verminderen, geen test van DNRS. Eén studie, zelfgeselecteerde gemeenschapssteekproef gemotiveerd om een psychologische behandeling te proberen.

Energy And Fatigue

Een kleine gerandomiseerde trial van een verwant hersenhertrainingsprogramma verbeterde symptomen van fibromyalgie en chronische vermoeidheid, maar weinigen voltooiden hetPreliminary
In plain terms

Een kleine studie van een hersenprogrammeerprogramma, toegevoegd aan standaardzorg, verbeterde zelfgerapporteerde energie, pijn en vermoeidheid bij mensen met fibromyalgie en chronische vermoeidheid. Slechts 7 mensen voltooiden de hertrainingsarm, dus het resultaat is fragiel.

In detail

In een enkelblinde gerandomiseerde trial verbeterde amygdala-hertraining (een bestaand hersenhertrainingsprogramma), toegevoegd aan een 1.5 dagen durende multidisciplinaire cursus, de zelfgerapporteerde lichamelijke gezondheid, energie, pijn, symptoombelasting en vermoeidheid vergeleken met alleen standaardzorg bij fibromyalgie en chronische vermoeidheid. Van de 44 gerandomiseerde personen voltooiden 21 het onderzoek, waarvan 7 in de hertrainingsgroep. Measured in: 44 patients with fibromyalgia and/or chronic fatigue randomized (21 completed), median age 48, 91% women, in a tertiary-care clinic. Zeer hoge uitval, met slechts 7 van de 22 die de hertrainingsgroep voltooiden, plus zelfgerapporteerde uitkomsten en een niet-geblindeerde interventie, maken dit een voorlopig signaal. Het testte amygdala-hertraining, een verwant programma, geen DNRS.

Evidence And Methods

De gepubliceerde ondersteuning voor programma's zoals DNRS is ongecontroleerd en zelfgerapporteerd; geen onderzoek heeft DNRS zelf getestPreliminary · mixed
In plain terms

Het beste onderzoek naar een vergelijkbare hersenhertrainingscursus vond dat mensen zeiden dat ze zich er na beter door voelden, maar er was geen vergelijkingsgroep, de gegevens waren zelfgerapporteerd, en de auteur werd betaald door het programma. Geen gecontroleerd onderzoek heeft DNRS zelf getest.

In detail

Het sterkste gepubliceerde onderzoek naar een vergelijkbaar hersenhertrainingsprogramma (amygdala- en insula-hertraining, het Gupta-programma) vond dat deelnemers hun gezondheid en functioneren na drie of meer maanden hoger beoordeelden bij 14 van de 16 chronische aandoeningen. Het had geen controlegroep, gebruikte zelfgerapporteerde gegevens uit een kleine, zelfgeselecteerde steekproef, en werd geschreven door een betaalde adviseur van het programma. Geen gerandomiseerd gecontroleerd onderzoek heeft het Dynamic Neural Retraining System zelf getest. Measured in: Self-selected users of a brain-retraining program reporting on their own health across multiple chronic conditions, cross-sectional survey. What could explain it instead: With no control group, the reported gains cannot be separated from the natural rise and fall of fluctuating illness (regression to the mean), the expectation set by a program people chose and paid for, and the greater tendency of those who improved to complete a follow-up survey. The author's financial tie to the program is a further source of bias.. Een voor-en-na-enquête onder mensen die zelf voor een programma kozen en ervoor betaalden, kan niet aantonen dat het programma de verandering veroorzaakte. Het weerspiegelt wat voorstanders aanhalen, en geen gecontroleerd onderzoek heeft DNRS getest.

How to Try It

Ways to Do It

Three ideas sit under DNRS: calming a sensitized nervous system, working with conditioned responses, and pacing activity. All three can be practiced for free, and they carry the most support behind them. The paid course packages them into a structured program with a fixed routine and coaching. Keep any of this alongside your medical care.

1
The free principlesFreeModerate

A daily calming practice such as meditation or slow breathing. Gentle pacing. And noticing what sets off your symptoms, without forcing yourself through them.

2
Books and apps$Moderate

Books on chronic pain, central sensitization, and pain science, plus low-cost meditation or nervous-system apps, cover much of the same ground the courses teach.

3
A structured course$$ to $$$Hard

DNRS and comparable programs sell a set curriculum, a fixed daily routine, and coaching. What they package is structure and support.

A routine you keep upTwo ways in

Whatever the source, these approaches all ask for a calming, pacing practice held steadily. Two routes reach it, at opposite ends of cost and effort.

DIY buildFreeHard

Assemble your own: a daily meditation or breathing practice, careful pacing, and a clinician working up and treating the underlying illness. It takes self-direction to build and sustain.

Buy one Affiliate$$ to $$$Moderate

Buy a structured course for the curriculum and the coaching. Someone else built the routine, so it is easier to follow.

Go Deeper

  • Anxiety: the same conditioned threat response drives anxiety, where behavioral treatment has a much larger evidence base.
  • Meditation: the calming, attention-training practice at the base of most brain-retraining routines, free and studied on its own.

The Chinese Medicine View

Chinese medicine reads long-running fatigue and sensitivity through several patterns. Exhaustion out of proportion to effort, poor digestion, and heaviness point to Spleen Qi deficiency, the failure to turn food into usable Qi. A deeper depletion, with cold, low reserves, and a long course, points to Kidney deficiency and the draining of Essence. The tension, irritability, and symptoms that come and go with stress belong to Liver Qi stagnation. Disturbed sleep and a mind that will not settle are read as the Shen, the spirit housed by the Heart, being unsettled.

The tradition treats mind and body as one system. A practice that calms the Shen and eases Liver Qi stagnation is held to calm the body as well, and calming practices have long been part of Chinese medicine. The tradition would not read that as retraining a brain out of an illness. It would treat the deficiency underneath. The classical caution 勞則氣耗, exertion consumes Qi, points to rest and tonifying the deficiency in someone whose reserves are low.

Two cautions follow, and a Five Branches practitioner would raise them:

  • A mind-calming practice does not replace treating the constitutional deficiency, and on its own it can leave the root untouched.
  • The tradition does not read the body's signals as errors to override. Nausea from a chemical, or a crash after exertion, is information about a person's state, and the pattern behind it still needs care.

If you work with a practitioner, the pattern is worth asking about, because the treatment depends on it and differs from person to person.

Cautions For This Practice

Extra restraint

Everything to be aware of is here, in one place. This practice suits most healthy people; a few situations call for real care.

Keep medical care going; this does not replace a diagnosis

Myalgic encephalomyelitis, multiple chemical sensitivity, fibromyalgia, and long COVID are physical illnesses, and they can occur alongside conditions that need to be found and treated. A brain-retraining course is not a substitute for a medical workup. Do not stop a treatment, drop an investigation, or leave a new or changing symptom unexamined because a program frames the illness as a brain response.

Be wary of marketing that promises recovery or blames setbacks on you

No trial has shown DNRS reverses these conditions. Be wary of any program that guarantees recovery, or treats a relapse as proof you practiced wrong. That blames the patient and adds guilt to an already hard illness. Reported improvement also reflects the expectation people bring to a program they chose and paid for.

In ME/CFS, do not push through symptoms

Post-exertional malaise, a worsening after even small exertion, is a defining feature of ME/CFS, and pushing through it can cause lasting setbacks. Treat any encouragement to override fatigue or ramp activity on a schedule with care. Pace to stay under the level that triggers a crash.

Start slow, be smart, read the research, and consult a professional if you have any concerns. This is here to inform your choice, not make it for you.

Common Questions

Does this mean my symptoms are imaginary?

No. These are physical illnesses. That a brain-directed approach is being studied does not put the problem in your imagination.

Is DNRS the same as the Gupta Program?

They are near-identical products. Both sell a set curriculum, a fixed daily routine, and coaching, for the same chronic conditions. The choice comes down to format, cost, and fit.

Is it safe to try?

The practice itself, calming routines and mental rehearsal, carries little physical risk for most people. The real risk is stopping medical care or pushing through fatigue in ME/CFS.
