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
Status
Completed
Conditions
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.
