The placebo-reward hypothesis: dopamine and the placebo effect

de la Fuente-Fernández, Raúl·2009·Parkinsonism & Related Disorders

Abstract

Based on the observation that the placebo effect in Parkinson's disease was mediated by the release of endogenous dopamine in both the dorsal and ventral striatum, in 2002 we formally proposed the placebo-reward hypothesis. This hypothesis establishes a link between the placebo effect and reward mechanisms, and predicts that the activation of the ventral striatum should be present in any placebo response, in any medical condition. In keeping with this prediction, functional neuroimaging studies have shown placebo-induced activation of the reward circuitry in Parkinson's disease, depression, and pain. In fact, recent evidence suggests that the release of dopamine in the ventral striatum likely triggers the activation of the endogenous opioid system in placebo analgesia. The placebo-reward hypothesis also supports the notion that the expectation of clinical benefit plays a major role in the placebo effect. Probability and trust, two key factors involved in shaping expectations, must therefore be essential to the development of placebo responses. The ventral loop of the basal ganglia circuitry (anterior cingulate cortex-ventral striatum-ventral pallidum- mediodorsal nucleus of the thalamus -anterior cingulate cortex) is a fundamental component of the neuroanatomy of the placebo effect.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
