Gender and the nocebo response following conditioning and expectancy

Journal of Psychosomatic Research, 2009
To investigate the role of Pavlovian conditioning and expectancy and of gender on the nocebo effects.Conditioning experiment: Forty-eight healthy male and female volunteers were investigated for 3 days using a standard rotation procedure. Subjects in the experimental group received a salient oral stimulus prior to rotation; subjects in the control ...

Placebo and Nocebo Responses, Cortisol, and Circulating Beta-Endorphin

Psychosomatic Medicine, 2003
The experiment tested whether the placebo and nocebo responses could be mediated via modulation of stress.Ischemic pain was induced in healthy volunteers (N = 59). When pain reached "7" on a 10-point scale, two groups of subjects received information that a pain relieving (the Placebo group) or a pain increasing (the Nocebo group) substance was ...

Drug-Related Information Generates Placebo and Nocebo Responses That Modify the Drug Response

Psychosomatic Medicine, 1999
Administration of the muscle relaxant carisoprodol and placebo was crossed with information that was agonistic or antagonistic to the effect of carisoprodol. It was investigated whether information alone induced physiological and psychological responses, and whether information modified the response to the drug.Half of the subjects received capsules ...

Placebo and nocebo responses in painful diabetic neuropathy: systematic review and meta-analysis

Pain, 2023
Abstract This preregistered (CRD42021223379) systematic review and meta-analysis aimed to characterize the placebo and nocebo responses in placebo-controlled randomized clinical trials (RCTs) on painful diabetic neuropathy (PDN), updating the previous literature by a decade. Four databases were searched for PDN trials published in the past 20

Nocebo response in Parkinson's disease: A systematic review and meta-analysis

Parkinsonism & Related Disorders, 2019
To estimate the magnitude of the nocebo response in Parkinson's disease and explore possible associations with study characteristics.Databases were searched up to February 2017. Placebo-controlled, parallel-group randomized controlled trials investigating pharmacological interventions in people with Parkinson's disease were included.

Movement Disorders, 2018
AbstractPlacebo treatment is associated with clinical improvements in many medical conditions, but is particularly important in Parkinson's disease because improvements are common, marked, and associated with objective neurochemical and neurophysiologic changes.

Increasing and dampening the nocebo response following medicine-taking: A randomised controlled trial

Journal of Psychosomatic Research, 2021
The nocebo effect is the adverse effects of treatment that cannot be attributed to a medicine. We investigated if we could increase or decrease nocebo responding following medicine taking. A nocebo explanation to reduce side effects was compared with a negative medication news item designed to increase side effects and a control condition.108 healthy ...

Mechanisms Involved in Placebo and Nocebo Responses and Implications for Drug Trials

Clinical Pharmacology & Therapeutics, 2011
Drug trials often compare active drugs with inert placebos under double-blind conditions. This standard design is increasingly being questioned in light of recent progress in understanding the mechanisms behind the placebo response.1,2 The growing knowledge of the neurobiology of placebo is forcing us to reconsider the significance of the placebo in ...

Metaforest Algorithm Insights: Predictors of Nocebo Response in ADHD

Current Psychopharmacology
Background: Predicting the nocebo response in randomized controlled trials (RCTs) is crucial as it can help minimize its influence and improve the evaluation of the side effects of interventions for ADHD. The aim of this study is to determine the effect of covariates related to study design, intervention, and patients’ characteristics on the nocebo ...

Nocebo responses to high-voltage power lines: Evidence from a prospective field study

Science of The Total Environment, 2016
Experimental studies suggest that nocebo responses might occur after exposure to equipment emitting electromagnetic fields such as high voltage power lines (HVPLs) or mobile phone base stations.The present study investigates to what extent health responses to a new HVPL can be explained by beliefs of residents regarding the health effects of HVPLs.We ...
