Abstract/Results: ABSTRACT:
The research presented here has shown that tolerance to drugs can be accelerated by conditioning processes. Placebo effects may be considered the opposite of tolerance, and we have shown that placebo effects may be objectively recorded by physiological measures (electromyography, skin conductance responses, and event-related potentials), as well as by behavioral and subjective methods. The placebo response, or more precisely, the expectation of drug effects, can add to the effect of the drug. Drug antagonistic expectations can also reverse the effect of the drug. There is some evidence that placebo effects are strongest when expectations are reinforced by administration of an active drug. Expectations have graded effects and may affect symptoms to a smaller or larger degree. Although drug effects can be considered stimuli, the investigation of the role of classical conditioning in drug use and drug effects involves special issues that must be carefully considered.

Placebo responses in psychology and medicine: New insights
Publication year: 2009

Abstract/Results: ABSTRACT:
The placebo response is often regarded as the enemy of evidence-based medicine, and raising placebo response rates in clinical trials (in depression, pain, irritable bowel syndrome, or Parkinson´s Disease) seem to underline this: when the “therapeutic gain” of medicine above the placebo response shrinks, it becomes increasingly difficult to bring new drugs to the market. On the other hand, family physicians and practitioners use the placebo response more or less excessively in every-day-practice, and it has been speculated that most therapeutic success is due to its operation. It has also been postulated that many if not all medicine approaches beyond drug treatment (psychotherapy, acupuncture, homeopathy) are based on placebo responses. Under these circumstances a rational approach to placebo and its practice in psychology and medicine is urgently needed. This symposium comprises four presentations from leading research groups that have – over the past years – fostered and developed placebo research. The scope of the workshop is to identify and characterize the placebo response both from an experimental standpoint as well as from different diseases.

Abstract/Results: ABSTRACT:
There is accumulating evidence from different fields of mechanistic placebo research that placebo effects result from real neurobiological processes. This minisymposium highlights the most important parts of the puzzle of the placebo effect and reviews these at different levels: neurophysiology, neuroanatomy, autonomic activity, behavior, and cognition. Speakers will emphasize the role of verbal suggestion, learning, empathy, and negative emotions in placebo responses.
Placebo effects refer to the reduction in symptoms after information that an effective treatment has been administrated, even if the treatment is inactive. L. Colloca will show that placebo effects may be learned via classical conditioning and that a placebo response can also follow the observation of another person who demonstrates pain relief in response to a treatment. K. Meissner will present evidence that placebo interventions can affect peripheral organ functions regulated by the autonomic nervous system, such as gastric motility, lung function, blood pressure, and the diameter of coronary arteries. Such placebo responses can be rather specific in nature and reflect the highly specific organization of autonomic pathways in the brain. M. Flaten will discuss whether placebo analgesia could be due to reduction in stress and negative emotions, which reduce feelings of pain. Event related potentials (ERPs) to painful stimulation are reduced by information that a painkiller has been administrated, and the reduction in ERPs is related to reduction in feelings of stress. A. Watson will present evidence that placebos reduce anticipatory brain (EEG) responses to painful stimuli, and that personality traits such as dispositional optimism and low state anxiety appear to be significant predictors of placebo responses. U. Bingel will provide evidence from fMRI studies that placebo analgesia involves top-down activation of endogenous analgesic activity via the descending modulatory system. The additional contribution of emotional regulation processes and areas such as the limbic system is a fundamental step that needs to be further addressed. T. Wager will present studies showing that placebo treatments elicit endogenous opioid release, engage frontal cortical-brainstem circuits during the anticipation of pain that predict the magnitude of placebo analgesia in new individuals, and reduce pain-related fMRI responses. These findings are replicable across laboratories and methods (PET, fMRI, EEG), are independent of attention and distraction effects, and exist even during active drug administration.

Abstract/Results: ABSTRACT:
Individuals undergoing treatment for a symptom like pain expect that the treatment will reduce the pain. Many studies show that healthy volunteers or patients in pain report less pain after inactive treatment, if they believe that active medication has been administrated. The reduction of pain can be partly blocked by systemic administration of naloxone, an opioid antagonist. There is reduced central nervous system activation to painful stimuli in individuals who have been given a placebo and told it is a painkiller. These findings suggest that the expectation of pain relief generates central nervous system opioid activity that inhibits pain transmission to the cerebral cortex. Expectations may thus lead to changes in central nervous system activity that reduces pain. It is proposed that expectations activate a homeostatic system that corrects perturbations to the system via negative feedback. The nocebo effect is the opposite of the placebo effect, and is due to induction of negative emotions. Part of the treatment of many symptoms and diseases is due to autonomic adjustments controlled by the central nervous system. The involvement of emotional processes in placebo effects could have important consequences for interpretation of data from randomized controlled trials.

Title: BIAL Grants
Start date: 1994
History:
In 1994 the BIAL Foundation launched a programme of science research grants with the aim of encouraging the research into Man’s physical and mental processes, namely in fields still largely unexplored but which warrant further scientific analysis, as Psychophysiology and Parapsychology.
Since its launch, applications to the BIAL grants have been increasing. Up to now 461 projects have been supported, involving more than 1000 researchers from 27 countries.
The approved applications have benefited from grants in amounts comprised between €5,000 and €50, 000. The amount to be granted is fixed by the Scientific board according to the needs of each project.
The supported projects have originated, until April 2013, in about 600 full papers, 172 out of which were published in indexed international journals with an average impact factor of 3.6 and a substantial number of citations (1665).
Among the BIAL Foundation fellows is worth highlighting the presence of scientists from prestigious universities from the United States, United Kingdom, Australia, Russia, Germany, Japan, France, Canada, and many others.
The BIAL grants are promoted biannually.

Abstract/Results: ABSTRACT:
OBJECTIVES
The present review investigated whether there are systematic sex differences in the placebo and the nocebo effect.
METHODS
A literature search was conducted in multiple electronic databases. Studies were included if the study compared a group or condition where a placebo was administered to a natural history group or similar cohort.
RESULTS
Eighteen studies were identified – 12 on placebo effects and 6 on nocebo effects. Chi-square tests revealed that 1) males responded more strongly to placebo treatment, and females responded more strongly to nocebo treatment, and 2) males responded with larger placebo effects induced by verbal information, and females responded with larger nocebo effects induced by conditioning procedures.
CONCLUSION
This review indicates that there are sex differences in the placebo and nocebo effects, probably caused by sex differences in stress, anxiety, and the endogenous opioid system.

Title:
Placebo effects on stress, but not on pain reports. A multi-experiment study
Publication year: 2021

Abstract/Results: Background: Contextual factors, such as participant/experimenter sex may moderate the placebo effects. We tested whether the participant and experimenter sex modulated placebo effects on experimentally induced pain and associated stress.
Objective: To investigate if (i) participant sex and (ii) experimenter sex influence placebo analgesia and subjective and physiological stress in two experiments employing a within-subjects and a mixed design, respectively. Placebo effects were investigated in pain reports, stress, and blood pressure.
Methods: Participants received painful stimulations and a placebo cream. In Experiment One (N = 59) participants underwent a placebo condition (PC) and a natural history condition (NHC) in random order. A placebo cream was applied in the PC and then the heat stimulation temperature was surreptitiously lowered. Identical stimulations were administered in the NHC, but with no cream, no information, and no lowered temperature. In Experiment Two, participants (N = 93) were randomly assigned to three groups receiving either a placebo cream with surreptitiously lowered intensity of electric stimuli (Placebo, PG), a placebo cream (Cream-Control, CCG) without changing the stimuli, or lowered intensity, but with no cream (Pain-Control, PCG) in a mixed design. All participants in both experiments received the same stimuli in the post-test as in the pre-test. Four experimenters (two females) in Experiment One, and five experimenters (two females) in Experiment Two conducted the studies.
Results: No placebo effect was seen on pain. However, there were placebo effects on stress, moderated by participant and experimenter sex: in Experiment One males in the PC had lower diastolic blood pressure (DBP) compared to males in the NHC. Participants in the PC had lower DBP compared to the NHC when tested by a female. In Experiment Two, participants expected more cream effectiveness when a female experimenter administered it, and reported lower stress in the PG compared to the PCG when tested by females.
Conclusion: Our findings highlight a distinction between placebo effects on pain and on associated stress. Secondly, female experimenters recorded lower physiological and subjective stress, higher effectiveness expectations, and lower pain from both sexes compared to male experimenters. Possible reasons for the failure to find a pain placebo effect are discussed.
