Hedonic Perception and Brain Activity Response to Meal

Not Applicable

Completed

• Conditions: Dyspepsia

• Registration Number: NCT02592239
• Lead Sponsor: Hospital Universitari Vall d'Hebron Research Institute

Brief Summary

The purpose of this study is to determine the relationship between brain activity and the perception of subjective hedonic sensations in response to a meal using functional MRI.

Detailed Description

Functional MRI brain imaging will be performed in patients with functional dyspepsia and healthy controls in basal conditions and after a palatable test meal. During the study, the cognitive response and the hedonic dimension will be measured using 10 score scales.
