Abstract

Placebos are drugs, devices, or other treatments that are physically and pharmacologically inert. The placebo effects are therapeutic responses to the context of the treatment process. They are mediated by factors, such as training of a patient, his/her expectations associated with treatment, as well as social conditions, the features of cognitive functioning, etc. and can affect the clinical and physiological responses caused by the health status. The analgesic effects of placebo in different types of pain syndromes reach 25–80%. The formation of placebo analgesia involves the brain structures that belong to the pain matrix and are implicated in the basic processes of perception, in the mechanisms of pain modulation, and in a number of other cognitive and affective processes, as well as in the emotional reactions not caused by pain. A deeper understanding of the mechanisms of action of placebo analgesia can optimize the strategy of current pain therapy.
