Functional Magnetic Resonance Imaging (fMRI) Exploration of Neurocognitive Processes Involved in Food Addiction (FA) in Obese Patients: Towards New Phenotypic Markers for an Optimized Care Pathway (AddictO)

July 27, 2023 updated by: Rennes University Hospital
Identification of the cerebral fMRI phenotype of obese patients with FA in cognitive task context based on food choice making

Study Overview

Detailed Description

Obesity is a worldwide epidemic associated with many complications. The treatment of obesity is a failure if it does not take into account eating disorders. Among them, food addictions seem to be frequent among obese patients. Clinical diagnosis and therapeutic approaches depend on presence of these FA. Moreover, eating disorders are associated with visible brain abnormalities in fMRI but the cerebral fMRI phenotype of FA is not known.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Patient with food addcitions

Patients (20) will be selected from the Yale Food Addiction Scale (YFAS): a validated screening of FA questionnaire.

Three clinical visits will be realized in less than two months

Measurement of body composition
Brain MRI
Resting energy expenditure
Blood sample
Questionnaires to characterize eating habits and depression
Experimental: Patients without food addictions

Patients (20) will be selected from the Yale Food Addiction Scale (YFAS): a validated screening of FA questionnaire.
