What role play stress and fear in forming of nocebo hyperalgesia?

The Center for Interdisciplinary Placebo Studies Leiden (IPS) aims to advance the understanding of placebo and nocebo effects, their underlying mechanisms, and their potential applications in clinical practice. IPS consists of a group of interdisciplinary researchers working at Leiden University with…

The placebo effect was completely new to her when Lingling Weng began the PhD project in Leiden. She is now a postdoc in China. 'It would be great to investigate the underlying mechanisms of placebo and nocebo effects with my current knowledge of EEG and fMRI.' PhD defence on 17 October.

People who have negative expectations about a treatment actually experience more pain. Merve Karacaoglu discovered in her PhD research that anxious and pessimistic individuals are particularly susceptible to this nocebo effect. However, this sensitivity comes with a silver lining.

We are confronted on a daily basis with news about the Corona virus and its consequences. We read alarming headlines like 'Dutch becoming increasingly anxious about Corona virus' or 'Huge fears and stress about Corona crisis'.

We aim to create an innovative e-learning and virtual reality training that helps healthcare providers to optimize placebo effects and minimizes nocebo effects via their communication.

The major aim is to examine the potential of learning the body to produce a similar physiological (autonomic, neuroendocrine, or immune) and physical (e.g., desensitization of persistent physical symptoms) response to placebo medication than to active medication (pharmacological conditioning). If proven…

The effects of many treatments are determined, to a significant degree, by factors other than the medicine or treatment itself. For example, placebo effects can be equal to the effect size of for example antidepressants or painkillers. Contributing factors are the trust placed in the doctor, the expectation…

Four Leiden researchers have been awarded a prestigious Vici grant by the Netherlands Organisation for Academic Research (NWO).

Health psychologist Andrea Evers is one of the 19 new members, selected by the Royal Netherlands Academy of Arts and Sciences (KNAW), who have been inaugurated on 16 September 2019. The Academy has now about 550 members.

Positive expectations about a medicine may help it to work more effectively, even if you tell patients about this placebo effect. The reverse, the nocebo effect, works in the same way. Health psychologist Stefanie Meeuwis found evidence for this in various studies. PhD defence 3 June.

Andrea Evers, Professor of Health Psychology at Leiden University, has won the Stevin Prize – alongside the Spinoza Prize, the highest scientific award in the Netherlands. She is the third social scientist from Leiden in a row to win one of these prizes. ‘Leiden attracts freethinkers.’

Positive expectations about treatment increase the likelihood of success. The new Center for Interdisciplinary Placebo Studies Leiden is therefore promoting research on the placebo effect and offering expertise and training for care providers. At the opening, the founders demonstrated their VR communications…

From painful joints to intense fatigue: a third of rheumatism patients suffer serious effects from this chronic condition and rely long-term on medication. Leiden psychologists are to receive a subsidy from the Netherlands Arthritis Foundation to investigate whether placebo techniques can help patients…

Medicines can work even if they have no active ingredient. The first international scientific conference on placebos will take place in Leiden from 2 to 4 April. Placebo researcher Andrea Evers, who is also chairing the conference, answers some pressing questions.

Andrea Evers is the new Professor of the brand-new unit of Health, Medical and Neuropsychology. She's getting off to a flying start in Leiden with a consolidator grant of the European Research Council (ERC). Her ambition? 'To work together with other disciplines; that way we can arrive at new insigh…
