Suggestible You: The Curious Science of Your Brain's Ability to Deceive, Transform, and Heal

purest form of the brain’s ability to alter reality, an undeniable neurochemical phenomenon. Another trick of the brain is placebo’s alter ego, the nocebo effect, whereby our brain is fooled into increasing our discomfort and perhaps even creating disease from thin air. A third category is hypnosis, an odd

…

the placebo has its own evil alter ego. Welcome to the dark and frightening world of the nocebo. Recall that placebo is Latin for “I shall please”; nocebo means “I shall harm.” Think of the nocebo as the placebo’s ugly, cantankerous stepbrother. The one no one wants to sit next to at

…

Thanksgiving. Just as placebos ease pain through brain processes, nocebos cause it. Like placebos, nocebos can be induced in the laboratory through deception. And like placebos, they tend to track alongside dopamine and opioid systems, affecting conditions like

…

pain, nausea, depression, and anxiety. Except nocebos make those conditions worse, not better. Nocebos can be found in almost all forms of disease. The difference is that (in the absence of horrible breaches of patients’ rights

…

) there’s really only one way to study nocebos in a controlled environment: via pain. Imagine that every time a rat hears a bell, it gets an electric shock. Bell, shock. Bell, shock.

…

just as if it had been shocked. Arguably, it may even feel the pain of a shock. That, at its most naked essence, is the nocebo response. But humans don’t need conditioning the way rats do. Just a couple of words will do the trick. The case of the woman

and the rose is one of the earliest documented examples of the nocebo effect, though the experiment took place long before the word had been coined. Once you know what to look for, you’ll start to

…

done with naloxone and opioids. Except this time, the subjects felt better when the CCK was blocked. What opioids are for placebos, CCK is for nocebos: a mechanism giving expectation power in the body. And whereas blocking opioids killed the placebo response, and made patients feel worse, blocking CCK actually supercharged

…

placebo response. They also seem to be easier to induce. Whereas with placebos we generally need to condition patients first, that’s not necessary with nocebos. For instance, when Luana Colloca was shocking me, she had to implement two rounds of color-guided torture before she switched them up and elicited

…

she said, “This is really going to hurt,” CCK, the stress hormone cortisol, and a healthy dose of raw panic would have kicked right in. Nocebo effects are a hell of a lot easier to create than placebo effects. Why is this? How is it that a negative expectation can be

…

stronger than a positive one? Think of nocebos and placebos in the brain as two different routes on Google Maps. They look similar, go to a similar place, and maybe even share a

…

few of the same highways, but they are still totally different routes. And nocebos have all the best shortcuts. This makes logical sense, since the aversion to pain is fundamental not just to being human but also to being

…

alive. Colloca notes that while the nocebo effect uses the same reward/expectation regions in the brain, it also taps into one more that placebos do not: fear. The hippocampus, among

…

few rewards for creatures that take a risk. But mostly they aren’t as big as the penalties. Nature favors the cautious. When talking about nocebos and side effects, scientists often refer to a sense of anxiety or “hypervigilance” that comes along with them. In other words, if you read

…

you wouldn’t stop to think about whether you were maybe feeling a little tired? One of the best places to understand the power of nocebos is in a drug trial. Take Ceregene’s trial for Parkinson’s disease, the one in which Mike Pauletich found out he got the placebo

Many diseases may be physical manifestations of fear, and understanding that may go a long way toward curing them. At this point, we have to

…

broaden our definition of fear. If nocebos can transform into chronic conditions, it’s probably not a conscious process. Just as placebos can happen beyond our conscious mind, so

nocebos must occur in some people whether they want them or not. But here we reach the limit of what the science of expectation can tell

I mean, how would you design an experiment causing chronic diseases in healthy human patients? That said, one group of physicians is asking tough

…

scientist who bemoaned the lack of effective pain treatments in chapter 2, often wonders about the unconscious triggers of chronic pain. He avoids words like “nocebo,” preferring more general terms like “susceptibility.” “You need to have a susceptible, vulnerable brain in place that is also taking this information and making bad

more than we can spot those prone to having placebo responses. And even if we could, they wouldn’t necessarily overlap with each other, since nocebos and placebos use separate systems in the brain. But although Mackey doesn’t understand what drives pain susceptibility, he’s had some luck in deprogramming

…

adjusting their minds—even forcing it to fade away into the background. Does this mean that chronic pain, fibromyalgia, and neuralgia are nothing but elaborate nocebos? Is some element of chronic pain caused by negative expectation? And if so, should we be thinking more about how the brain perceives pain than

…

health issues. And although it hasn’t been documented, it’s fair to assume that—like placebos—social pressure enhances and reinforces a nocebo. As with placebos, a good nocebo needs to tap into a powerful, plausible story with vague, placebo-prone symptoms. For instance, in 2010 a mysterious disease of headache

…

course we can’t be sure some of these people weren’t genuinely sick, nor can we link the reactions directly to the kinds of nocebos we see in a laboratory. That said, among the reasons scientists later said the diseases were psychosomatic are (1) like most placebos, they dissipated

She writes about
