Neurofeedback intervention to improve cognitive control in emotional overeating
fNIRS-based Neurofeedback Intervention for Cognitive Control Improvement in Emotional Overeating
This study is testing whether a brain training program can help people who eat too much when they're emotional learn to control their eating better.

What this trial studies
This intervention focuses on using functional near-infrared spectroscopy (fNIRS) to provide neurofeedback aimed at improving cognitive control in individuals who experience emotional overeating. Participants will receive real-time feedback on their brain activity, allowing them to learn how to modify this activity to better manage their eating behaviors. The study will include both active neurofeedback and sham neurofeedback sessions, along with assessments of oral microbiota and questionnaires. The goal is to explore the efficacy of fNIRS-based neurofeedback as a tool for addressing hyperphagia and related eating disorders.
Who should consider this trial
Good fit: Ideal candidates for this study are adults aged 18 to 50 with a normal body mass index who are right-handed and fluent in French.
Not a fit: Patients with certain medical implants or conditions that prevent participation in neuroimaging techniques may not benefit from this study.
Why it matters
Potential benefit: If successful, this intervention could help patients better manage emotional eating and reduce the risk of developing eating disorders and related health issues.
How similar studies have performed: Previous studies using neurofeedback techniques have shown promising results, suggesting potential efficacy for this novel approach.
