Brain Retraining: How to Choose a Program?

Alyssa Luck · May 5, 2022 · Leave a Comment

“Brain retraining” has become an increasingly common approach to chronic illness. It’s especially popular for conditions like multiple chemical sensitivities, EMF sensitivity, chronic fatigue syndrome, fibromyalgia, and POTS, but people have had success with an enormous range of chronic mental and physical conditions, from depression and anxiety to IBD and other autoimmune disorders.

I’m a bit biased because this is where my focus currently is for my own health, but I do think brain/nervous system approaches are the missing piece for many with chronic illness, especially people who have tried every diet and supplement regimen under the sun and still haven’t seen much improvement.

The central ideal of these approaches is that it isn’t the environment that’s the problem – it’s the way your body is responding to it. Maladaptive response patterns can be conditioned into us in a number of different ways and at any point in our lives, but the common denominator is that the body has learned to operate from a “threatened” mode, rather than a “safe” mode. It’s not quite as simple as the classic dichotomous “fight or flight” vs. “rest and digest,” but that idea does roughly get at what’s going on.

The body does not heal efficiently when it feels threatened, so all these programs use various tools to teach the body that foods and social experiences and exercise and other environmental stimuli do not need to be defended against; that it is safe. (If this sounds a little intangible or pseudosciencey, I hear you – one of my current research goals is to bring some concreteness to these approaches!)

Dynamic Neural Retraining System: Can DNRS Work for IBD?

Alyssa Luck · May 5, 2022 · Leave a Comment

Summary: The Dynamic Neural Retraining System was created by Annie Hopper to heal herself from severe multiple chemical sensitivities (MCS), and since 2008 has been widely used by others with MCS and other “mysterious” chronic illnesses such as fibromyalgia, chronic fatigue syndrome, and even long-COVID, with seemingly miraculous results. The program is built upon the premise that at the root of all these illnesses is a maladaptive brain response to environmental stimuli, causing the body to react as if harmless stimuli are life-threatening. Although DNRS is not widely used or marketed for IBD, evidence indicates that maladaptive nervous system responses are likely a component of the disease, and at least one IBD patient has reported success using DNRS. Although DNRS is not designed with IBD patients in mind, the principles it teaches may very well be the missing piece for many people who have tried just about everything else.

The Dynamic Neural Retraining System, or DNRS, is one of those programs that appears to toe the line between “this is totally miraculous” and “this is total bullshit.” How could someone possibly go from, say, being wheelchair- and house-bound, and only able to eat a few foods, to being totally and completely healthy, just by doing some mental exercises?

It sounds like magic, but this is the promise of neuroplasticity. It’s not easy, but it’s powerful. And for many with ulcerative colitis or Crohn’s disease, it could be the missing piece – the reason that all of the drugs and diets and supplements haven’t worked, despite great effort and dedication.

Hypnotherapy for Ulcerative Colitis and Crohn’s Disease

Alyssa Luck · Mar 14, 2022 · Leave a Comment

Summary: Hypnotherapy is a mind-body therapy that may have therapeutic potential for IBD, although it’s a bit less practical to implement at home compared to other mind-body therapies such as meditation. Thus far, clinical trials in IBS have shown more impressive results than those in IBD, but there is some preliminary evidence that hypnotherapy could help maintain remission in UC patients who are already in remission, and reduce heart rate and inflammatory markers in those with active disease. The precise mechanism of action behind hypnotherapy remains to be elucidated, but the research of Robert Becker into the electrical systems of the body provides some fascinating glimpses into what may be happening to the mind and body in states of hypnosis.

Meditation and Mindfulness for Ulcerative Colitis and Crohn’s Disease

Alyssa Luck · Mar 14, 2022 · Leave a Comment

Summary: Meditation and mindfulness are becoming increasingly popular in the health sphere, and rightly so – ample evidence indicates that these practices are extremely beneficial for health. However, as far as their practical efficacy in managing IBD, the jury is still out. Clinical trials in IBD have fairly consistently shown improvements in overall quality of life, but thus far haven’t demonstrated improvements in flare rate or severity. That said, trials in a variety of patient populations have shown that mindfulness appears to down-regulate NF-κB activity, reflecting an overall less inflammatory gene expression profile. Other evidence supports the idea that mindfulness markedly changes how the central nervous system physiologically responds to stressors, including down-regulation of sympathetic nervous system and HPA-axis activity. Taken together, it appears likely that mindfulness could confer more measurable benefits with regards to inflammation and disease progression in IBD over the long term.

Mind-body medicine is currently an area of particular research focus for me, so you can expect this post to be expanded and updated in the near future! Follow me on Instagram for personal content related to mind-body medicine, as well as snippets of interesting research that might not make it into a blog post.

Mindfulness is one of those golden health practices that I call “no brainers” – in other words, you have nothing to lose and everything to gain. At the outset, I can say that I’d recommend some type of mindfulness practice to every person with IBD, almost without exception (and anyone who knows me knows that I’m not usually in the business of recommending things).

So if you want to learn more, read on. Otherwise, save your time and go meditate!

Vagus Nerve Stimulation for IBD

Alyssa Luck · Jan 27, 2022 · Leave a Comment

Summary: Vagus nerve stimulation is an up-and-coming intervention for chronic inflammatory disorders including IBD. Clinically, it involves electrical stimulation of the vagus nerve through implanted or external devices, but natural methods such as yoga, meditation, and specific breathing practices have also been shown to increase vagal tone. Research in both animals and humans indicates that stimulation of the vagus nerve is able to reduce inflammation via various neural and hormonal pathways, with similar targets to popular pharmacological IBD treatments. Clinically, this is an exciting new treatment that is actively being researched; practically, vagus nerve stimulation via natural methods provides a safe way to reduce inflammation and improve health.

Technical details of clinical vagus nerve stimulation

What is Vagus Nerve Stimulation?

In the clinical research setting, vagus nerve stimulation (VNS) refers to stimulation of the vagus nerve via electrical impulses. This can be done either invasively, via a surgical implant, or noninvasively, via electrodes stuck to the skin in the ear. (For technical details, check out this section at the bottom of this article.)

VNS has been approved by the FDA for the treatment of drug‐resistant epilepsy and depression, and interest is building for its application in the treatment of chronic inflammatory disorders such as rheumatoid arthritis (and of course, IBD). VNS is not yet available as a clinical treatment for IBD, but two small trials have been conducted in patients with Crohn’s Disease (CD), and two more trials are underway.

Outside of clinical research, talk of stimulating the vagus nerve typically refers to at-home practices that naturally stimulate the vagus nerve, including things like deep breathing and meditation. More on these techniques below!

Photo dump from the last year. Thanks to everyone Photo dump from the last year. Thanks to everyone who made 28 the best yet - excited for 29🥰

(PS. In case anyone wants to know what it’s like in my head, I was going to write something like “year 28” or “my 28th year” but then I realized that the year between your 28th and 29th birthdays is not your 28th year of life, it’s your 29th year. I am turning 29 because I have been alive for 29 years. So then I had a whole thing about how to word it without being inaccurate and ended up going with what you see above which is vague and weird but the point is it was a good year and I love all the people in my life dearly)
Biology of Belief (2005) was written by Bruce Lipt Biology of Belief (2005) was written by Bruce Lipton, who earned a PhD in developmental biology in 1971 and was an anatomy professor and academic researcher in the 70s and 80s. Despite the book's presentation and Lipton's background, this is not a science book. It is an exposition of an ideology, supported by haphazard and poorly contextualized nuggets of evidence, rhetorical leaps, and a mind-boggling overuse of analogies. 

The book largely failed to deliver on its promised content. What it does is argue for the primacy of the environment over DNA in controlling life; propose that the cell membrane rather than the nucleus is the "brain" of the cell; invoke quantum physics to explain why modern medicine fails; explain that our behavior is largely controlled by our subconscious mind; inform parents that they therefore have a great deal of control over the destiny of their children; and conclude that humans must become nonviolent protectors of the environment and of humanity because Everything Is Connected.

It’s not that these points aren’t relevant to the topic at hand - they are. But they were not connected in a coherent way that would explain how “belief” actually works (like…biologically), and the treatment of scientific concepts throughout was careless, or perhaps disingenuous.

I think he's correct about many things, some of them being common knowledge. For instance, the "new" science of epigenetics is now old news, as is the critical role of parenting and early environment in shaping a child’s future. But however important these and attendant concepts may be, the book did not do a good job explaining, supporting, or connecting them. 

As far as practical guidance, he refers the reader to a list of resources on his website, which is fine, but I expected some scientific insight into how/why those modalities work. None was given. 

On the plus side, the book was quite thought-provoking, and I came away with loads of references and topics to follow up on. My favorite line? "There cannot be exceptions to a theory; exceptions simply mean that a theory is not fully correct."
Friedrich Nietzsche, The Gay Science (section 382) Friedrich Nietzsche, The Gay Science (section 382), as quoted in the introduction to Thus Spoke Zarathustra because I like the translation better.
This paper totally changed the way I think about e This paper totally changed the way I think about early nervous system development and the relationship between physiology and sociality. 

The authors propose that newborn babies are not inherently social, and have just one goal in life: physiological homeostasis. I.e. staying alive. This means nutrients, warmth, and regulation of breath and heart rate, i.e. autonomic arousal (it’s well-accepted that newborns sync their breathing and heart rate with caregivers through skin to skin contact). 

All these things are traditionally provided by a loving caregiver. So what the baby experiences during the first weeks of life, over and over, is a shift from physiological perturbation to homeostasis (a highly rewarding event inherently) REPEATEDLY PAIRED with things like the sound of a caregiver’s voice and seeing their face. Thus, over time, the face/voice stimuli become rewarding as well. 

The authors argue that THIS is the beginning of humans’ wiring for sociality, and may explain why loving social interactions can have such a profound regulating effect on physiology throughout life: because the brain was trained for it at an early age. 

This framework holds all kinds of fascinating implications for what happens if that initial “training” isn’t so ideal. What if the return to nutritional homeostasis via feeding is paired with negative expressions and vocalizations rather than loving ones, perhaps as could occur with PPD? What happens if the caregiver has poor autonomic regulation, such that social stimuli become paired with cardiorespiratory overexcitement in the baby? Could that have potential for influencing later introversion vs extroversion? (Because if social interaction is paired with autonomic overexcitement, that could lead to social interaction literally being more energetically draining, which is what introverts experience. Thoughts?)

For my energy metabolism enthusiasts: Table 1 in the paper draws a link between metabolic rate and sociality across species. Swipe for a screenshot. 

Anyway, check out the paper! It’s free, just google “growing a social brain pdf.”
I’ll be under general anesthesia in a couple day I’ll be under general anesthesia in a couple days to have two tooth implants placed, and I think I’ll take the opportunity to have a little heart-to-heart with my subconscious mind. A bit of medically-assisted self-hypnosis, if you will. 

I randomly stumbled upon these papers a couple months ago - an RCT showing reduced post-op pain in patients who listened to recorded positive messages while under general anesthesia, plus a post-hoc analysis of the same data that found reduced post-op nausea and vomiting in a subset of high-risk patients. 

The full review paper from the first slide is unfortunately in German, but it has long been recognized that even when unconscious, the patient is listening (for better or for worse). 

It boggles my mind that it isn’t standard of care to have patients listen to recordings like this while under sedation, considering that almost nothing could be easier, safer, or cheaper, and we have at least some evidence of significant efficacy. I mean c’mon, what more could you want from an intervention? 

(Yeah, I know. Profit. If anyone still thinks that our medical system operates with patient well-being as the foremost goal, you’re deluding yourself.)

“There should be a fundamental change in the way patients are treated in the operating room and intensive care unit, and background noise and careless conversations should be eliminated.”

“Perhaps it is now time to finally heed this call and to use communication with unconscious patients that goes beyond the most necessary announcement of interventions and is therapeutically effective through positive suggestions. When in doubt, assume that the patient is listening.”
If you've seen "vagus nerve exercises" that have y If you've seen "vagus nerve exercises" that have you moving your eyes or tilting your head, you've probably encountered the work of Stanley Rosenberg. The exercises he created and introduced in his 2017 book now appear in instructional videos all over the internet. 
 
The book itself has much to recommend it: it's accessible, it's practical, it's inspiring. But it has one major flaw: the solid practical and informational content regarding the cranial nerves is framed in terms of the scientifically dubious polyvagal theory. 
 
I particularly enjoyed the book as an introduction to the therapeutic arena of bodywork, of which Rosenberg is a skilled practitioner. His book is full of case reports that demonstrate how immensely powerful extremely subtle movements and physical manipulations can be. These do need to be kept in perspective: it's a small sample size of the most remarkable cases, and the results were achieved within the supportive clinical environment of a skilled practitioner. You can tell from his descriptions how refined his technique is. But nevertheless, it was a paradigm-shifting read for me, and the exercises give you something concrete to play around with. 
 
The book also brought the cranial nerves and the concept of “social engagement” to the fore as arbiters of health. Rosenberg has a solid background in cranial nerve anatomy and shares many interesting tidbits and considerations that you don’t typically hear; for instance, the potential impact of dental and orthodontic work on cranial nerve function.
 
So, is it worth reading? If any of the above piques your interest, go for it! Just read my post on polyvagal theory first – you can use the book to practice separating the wheat (solid informational content) from the chaff (pseudoscientific framing). If nothing else, the book is a nice reminder that genuine healers who get lasting results for their patients do exist.

But if you just want to try the exercises, you can easily find them all on YouTube. 

“You learn techniques to understand principles. When you understand the principles, you will create your own techniques.” -Stanley Rosenberg
