Tematika

The use of placebo treatments was an inherent part of medicine for thousands of years, and during the second half of the 20th Century it became an inevitable element of medical research due to the introduction of placebo-controlled clinical trials. Despite this fact, the research methodology to measure the effectiveness of placebo effect was clarified only at around the beginning of the 21st Century. At the same time, research on the neurochemical mechanisms underlying placebo responses gained a new impetus. Currently, therefore, we have a much clearer understanding of placebo effect in the context of evidence-based medicine than before, which raises new types of ethical questions as well. During the course we will examine various aspects of the phenomenon of placebo effect, and the students will gain knowledge of the current research results. The main topics of the course: the history of the use of placebo therapies, the role of placebo effect in medical research, the psycho-social factors contributing to placebo effect, neurochemical mechanisms underlying the placebo responses, ethical implications.
