Neurofeedback intervention to improve cognitive control in emotional overeating

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

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.
