The power of placebos is commonly associated with the placebo effect. In contrast, detrimental effects related to the use of a placebo are little studied and less well recognized. This chapter covers the nocebo and lessebo effects defined, respectively, as expectation of harm in the form of adverse events in a placebo arm and reduction of therapeutic ...

There are four general reasons for clinical improvement in a patient’s condition: (1) natural history of the disease; (2) specific effects of the treatment; (3) regression to the mean; and (4) nonspecific effects of the treatment that are attributable to factors other than the specific active components. The latter effect is included under the heading ‘

The role of learning in nocebo and placebo effects
Acute Pain, 2008The nocebo effect consists in delivering verbal suggestions of negative outcomes so that the subject expects clinical worsening. Here we show that nocebo suggestions, in which expectation of pain increase is induced, are capable of producing both hyperalgesic and allodynic responses. By extending previous findings on the placebo effect, we investigated

Pain and the Placebo/Nocebo Effect
2011In the last 20 years, placebo and nocebo research has provided scientific ground for a phenomenon once believed to be only patient mystification, or at best a variable to control in clinical trials. Neurochemical, pharmacological and neuroimaging studies are elucidating the mechanisms by which the activation of identifiable neural pathways produces ...

The Nocebo Effect of Informed Consent
Bioethics, 2012ABSTRACTThe nocebo effect, the mirror‐phenomenon to the placebo effect, is when the expectation of a negative outcome precipitates the corresponding symptom or leads to its exacerbation. One of the basic ethical duties in health care is to obtain informed consent from patients before treatment; however, the disclosure of information regarding potential

Ulysses Contracts and the Nocebo Effect

The Power of Labeling in Nocebo Effects
2018Nocebo effects comprise two broad types: primary nocebo effects, in which overall treatment efficacy is reduced; and nocebo side effects, which result in the increased experience of unpleasant secondary side effects. An important factor in generating nocebo effects of both types is the patient's expectations of how well a treatment will work, and how ...
