Prefrontal brain activity during emotion regulation in women with binge-eating
Official title: Study of Emotional Regulation and Underlying Prefrontal Activity in Binge Eating Disorder
Run by Centre Hospitalier Universitaire de Besancon · NCT06864065 · Data updated 2026-11-12
This study tests whether women with binge-eating show different prefrontal brain and bodily responses when trying to down-regulate negative emotions compared with healthy women with and without emotional eating.

Is this trial a fit for you?
✓Likely a good fit
Ideal participants are right-handed women aged 18–60 with a DSM diagnosis of binge-eating disorder, able to travel to a participating French center and covered by the French social security system.
✕Probably not a fit
People with current other psychiatric disorders, neurological disease or significant medical conditions, prior bariatric surgery, substance or behavioral addictions, or skin problems at recording sites are unlikely to benefit and are excluded.

What this trial studies
This multicenter exploratory interventional study compares four groups of right-handed women (BED, BMI-matched healthy with emotional eating, BMI-matched healthy without emotional eating, and normal-weight healthy controls) while they perform a task to down-regulate negative emotions elicited by pictures. Cerebral activity over the prefrontal cortex will be recorded using functional near-infrared spectroscopy (fNIRS) alongside autonomic measures (skin conductance, pulse, respiration). The protocol focuses on between-group differences in cognitive control of negative emotion and subjective emotional experience. Sites in Besançon and Dijon will enroll participants who meet inclusion and exclusion criteria and complete the laboratory task under standardized conditions.
Why it matters
Potential benefit: If successful, the results could help identify brain and physiological markers of impaired emotion regulation in BED that inform future targeted therapies or diagnostics.
How similar studies have gone: Previous neuroimaging work (primarily fMRI) has reported altered prefrontal responses during emotion regulation in eating disorders, so the general approach has supporting evidence, but using fNIRS plus autonomic measures in BED is relatively novel.
