On Placebos and Depression Drugs

We note an interesting ‘counter narrative’ emerging – that is, scepticism about the commonly held view that drug treatments designed for mood disorders such as depression often engage the Placebo Effect. In this counter-narrative,

“Drug trials don’t show much in the way of classic placebo effects. The rise in placebo responses over the years is more likely due to the supportive factors in drug trials…and increasing problems with enrollment.”

The new finding—no upward trend in placebo responses—is unexpected and certain to be contested. Meanwhile, it stands as a rebuke to a popular narrative. By that account, drug effects had been hyped, expectations soared, and the inflated hopes were reflected in rising placebo response rates.”

This is fine, except the counter-narrative also resonates with challenges about the efficacy of conventional ‘gold-standard’ ‘blind’ ‘placebo controlled’ drug trials, where it has been shown that trials funded by drug companies (who by definition have a vested interest in their outcome) are 30% more likely to return ‘favourable’ results than trials which are not funded in this way. The ‘placebo effect’ might be the design and execution of the trial itself, not the actual function and efficacy of the placebo …!

The Guardian Weighs in on the Placebo effect

An excellent article in The Guardian on the placebo effect.

‘There is now evidence showing some people, known as “placebo responders”, do feel or get better after unwittingly, or even wittingly, taking a placebo – and it’s not just psychosomatic. Several studies are pointing to a biological basis for the placebo effect, with the latest research focused on a region of the brain known as the mid-frontal gyrus, which runs along the frontal lobes just above the eyes.’

Is ‘the Sugar High’ Just a Parenting Myth?

According to The Science of Us  (and leaving aside the well known issues related to our excessive consumption of the stuff) the concept of ‘the sugar high’ is something of a parenting urban legend; plenty of research has shown that feeding kids sugar doesn’t make them hyper. What it does do, though, is prime their parents to look for signs of misbehavior.

In part, pediatric researcher Mark Wolraich told Geggel, the misconception stems from the fact that sugar often marks a special occasion: When kids are stuffing themselves with birthday cake or Halloween candy, they’re already in a situation where they’re going to be naturally amped up. But “[parents’] ideas are reinforced by seeing it in those circumstances,” Wolraich said. “The placebo effect can be very powerful.”

Emotions, epigenetics, placebos

A fascinating article on the many levels at which we might work to heal ourselves unconsciously. A quote from Dr Bruce Litpon, author of The Biology of Belief: Unleashing the Power of Consciousness, Matter & Miracles

“The placebo effect should be the subject of major, funded research efforts. If medical researchers could figure out how to leverage the placebo effect, they would hand doctors an efficient, energy-based, side effect-free tool to treat disease. Energy healers say they already have such tools, but I am a scientist, and I believe the more we know about science of the placebo, the better we’ll be able to use it in clinical settings.”

Placebos in sport

Capture

There’s so much attention right now given to Olympic atheletes’ use of ‘placebo’ rituals and objects, from favourite items of underwear to ancient Chinese ‘cupping’ techniques and herbal supplements.

“Judo gold medalist Kayla Harrison wears the lucky socks that were a gift from her grandmother. Hockey player Alex Danson spins her stick 15 times before each game. Tennis player Rafael Nadal takes alternating sips from two water bottles at every break between games.”

Quartz looks in some depth into the phenomenon.

It’s unpacked further here.

“In sports, it’s a little different in that in the vast majority of cases relying on the placebo effect probably won’t hurt, and in many cases might actually help because of the power of belief. Aside from some potential BO, is it really a problem that an athlete regularly wears the same t-shirt under his uniform to help with on-field success? In fact, savvy coaches regularly use various placebo approaches when trying to help their team with belief — and often these tactics work.”
