A new study published in Brain indicates that successful treatment for insomnia may not actually require complicated neurofeedback (direct training of brain functions).
Rather, it appears patients who simply believe they’re getting neurofeedback training appear to get the same benefits.

The research effort on the placebo effect deepens and widens.
“In a report published online Feb. 15 in The BMJ, researchers at Stanford call for more health care providers to place emphasis on the importance of individual mindsets and social context in healing … (and) to develop more studies that measure the physical effects of these psychosocial elements to understand and quantify patients’ subjective experiences of expectations, connection and trust.”
“We have long been mystified by the placebo effect,” Crum said. “But the placebo effect isn’t some mysterious response to a sugar pill. It is the robust and measurable effect of three components: the body’s natural ability to heal, the patient mindset and the social context. When we start to see the placebo effect for what it really is, we can stop discounting it as medically superfluous and can work to deliberately harness its underlying components to improve health care.”

“I was just amazed that you could change what price you were going to launch a product at, and you could change what brand it was, and people would have dramatically different impressions of that product. And they would tell you incredibly different things about the product: they thought it was made of different materials, they thought it weighed more or it weighed less. Really out-there stuff that, at the time, we joked about but we couldn’t explain.”

This question/comment/assumption comes up a lot when we talk to people about placebos and the placebo effect. ‘It works’ (is the assumption) ‘if people believe it’s something else’ …
Like the ‘real’ thing, perhaps …? We’ve posted on this before, and it seems the research is becoming more robust and rigorous.

Many people take glucosamine and chondroitin supplements for arthritis pain, but a controlled trial has found no evidence that the combination works. In fact, in this study, the placebo worked better.
Spanish researchers randomized 164 men and women with knee osteoarthritis to take a single daily dose of 1,500 milligrams of glucosamine and 1,200 of chondroitin, or an identical looking placebo. The study is in Arthritis & Rheumatology.

New research has shown that patient’s envisioning and expecting positive results from major surgery, including open heart surgery, will over time actually recover and heal more effectively.
“Optimizing patients’ expectations pre-surgery helps to improve outcome 6 months after treatment. This implies that making use of placebo mechanisms has the potential to improve long-term outcome of highly invasive medical interventions”
Placebo treatments seem to have an effect on pets … but is the effect on the pets themselves, or ‘second hand’ through a placebo effect on pet owners? Find out here.
NBC News reports:
“The study included about 300 kids aged 8 to 17, enrolled at 31 centers. They had 11 migraines on average in the month before the study began and were randomly assigned to take either of the drugs or placebo pills daily for six months. Migraine frequency in the study’s last month was compared with what kids experienced before the study. At least half of kids in each group achieved the study goal, reducing migraine frequency by half.”
The same report, with a couple of videos, is over at CBS.
Quite a buzz lately about the placebo effect and back pain, extending from a randomized control trial in Portugal.
“Our findings demonstrate the placebo effect can be elicited without deception. Patients were interested in what would happen and enjoyed this novel approach to their pain. They felt empowered.” – Lead author Claudia Carvalho, Ph.D., ISPA
“It’s the benefit of being immersed in treatment: interacting with a physician or nurse, taking pills, all the rituals and symbols of our healthcare system,” (says placebo researcher Ted Kaptchuk, Professor of Medicine at Harvard Medical School). “The body responds to that.”
While this study focused on chronic pain, Kaptchuk says it is possible that patients with other conditions that involve self-observation – such as fatigue, depression, or digestive problems – may benefit from open-label placebo treatment.
“You’re never going to shrink a tumor or unclog an artery with placebo intervention,” notes Kaptchuk. “It’s not a cure-all, but it makes people feel better, for sure. Our lab is saying you can’t throw the placebo into the trash can. It has clinical meaning, it’s statically significant, and it relieves patients. It’s essential to what medicine means.”

In Why Placebos Really Work: The Latest Science the Wall Street Journal points to the increasing frequency of ‘serious’ science envisioning health interventions that consciously include placebos and invoke the placebo effect. It seems the mind-body divide is something of an illusion!
Nevertheless, even though at least 50% of doctors actively prescribe placebos – often active drugs in such low doses that there is no apparent therapeutic benefit, or vitamins, antibiotics or over-the-counter analgesics like aspirin – they are still disinclined to prescribe a sugar pill. I guess they feel like it’s cheating, somehow.
