A few months ago I wrote about Fabrizio Benedetti’s research on the neurobiology of the placebo response, and a discussion about placebos and ethics ensued in the comments. Now Dr. Benedetti has written about that issue in a “Perspective” article in the journal World Psychiatry, “The placebo response: science versus ethics and the vulnerability of the patient.”
We have learned that verbal suggestions can activate neurotransmitters and modulate pain perceptions, and positive expectations can activate endogenous opioid and cannabinoid systems. A complex mental activity has objective effects on body physiology. Words and drugs can activate the same mechanisms. Drugs are less effective without therapeutic rituals. We are delving deep into human foibles and vulnerable traits at the center of human interactions. What implications do these insights into mind-body interactions have for patient care?
