Placebo analgesia effects have been found to reflect decreases in pain beyond that accounted for by the natural history of a pain condition. These effects clearly are influenced by the effectiveness of previous active treatments (ie, conditioning) as well as by environmental factors that provide cues/suggestions for analgesia. However, external factors are effective insofar as they provide expectations for pain reduction and a lowering of desire for relief.

Basic scientists started elucidating the neurophysiological and neuropharmacological processes that mediate the placebo response.

In this article, we discuss the clinical relevance and the ethical problems associated with the use of placebos. Although a recent meta-analysis questioned the power of placebo, good evidence exists that placebos can lead to important improvement in many clinical conditions. A part of the conflict on the ethics of the use of placebos in randomized clinical trials can be solved by distinguishing between ethical guidelines for good clinical practice and for clinical research.

However, very little is known about the neurobiological mechanisms of either placebo analgesia or the generation of expectancy that enables it. To address this issue, I used functional magnetic resonance imaging to quantify placebo-induced changes in pain-processing brain regions during the experience of pain. Results show placebo-induced decreases in contralateral<span> thalamus, anterior insula, and anterior cingulate, and increases in prefrontal brain regions that may maintain expectations for pain relief. These findings are discussed in light of several proposed neuropsychological mechanisms of placebo analgesia: altered appraisal of threat, diversion of attention, and activation of descending opioid systems for spinal control. These results suggest that placebo treatment alters the appraisal process, reducing the subjective distress caused by pain.</span></p></div>","PeriodicalId":101158,"journal":{"name":"Seminars in Pain Medicine","volume":"3 1","pages":"Pages 22-30"},"PeriodicalIF":0.0,"publicationDate":"2005-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.spmd.2005.02.003","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81242662","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Expectation has been shown to be critically involved in placebo responses. We argue that in patients with Parkinson’s disease, placebo-induced expectation of clinical improvement is a form of expectation of reward, which results in striatal dopamine release.
