Obesity Clinical Trial - fMRI Study of Emotion Regulation in Patients

Status Recruiting

Clinical Trial Summary

Obesity is a major public health problem and Binge eating disorder (BED) is very frequently observed in patients considered for weight loss surgery and seems to influence their outcome critically. Literature highlights a global emotional overload in individuals with BED, but few are known on the mechanisms involved. The purpose of this study is to fill this gap by comparing the neurofunctional profiles of emotion regulation between patients suffering from obesity, with or without BED and healthy participants during the performance of emotion regulation tasks. Results may help to understand the neural bases of the impairments observed in patients with obesity, with or without BED, which may in turn help to propose, in the long term, potential new therapeutic approaches.

Clinical Trial Description

Obesity is a major public health problem and frequently associated with Binge eating disorder (BED) in patients considered for weight loss surgery and seems to influence their outcome critically. It may be due, in part, to an ineffective or a maladaptive emotional regulation. Emotion regulation is the ability to exert control over one's own emotional state. The relative absence of this ability would indicate the presence of difficulties in emotion regulation, or an emotion dysregulation. Individuals with disordered eating may have a greater vulnerability to use maladaptive emotion regulation strategies. In the eating behaviours, an emotion dysregulation can cause weight gain that can lead to overweight or obesity. Accordingly, patients suffering from obesity, and with BED may have a greater vulnerability to use maladaptive emotion regulation strategies. However, few studies have investigated the neurofunctional profiles of emotion regulation in patients suffering from obesity with and without BED and seeking bariatric surgery. The aim of the study is to explore the neural correlates of emotion regulation in patients suffering from obesity, with or without BED, in comparison with those of healthy participants. We also aim to describe the relationship between the neural correlates, eating behaviours and assessed psychological profiles. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
