fNIRS-based Neurofeedback Intervention for Cognitive Control Improvement in Emotional Overeating
A study testing Neurofeedback with functional near infra-red spectroscopy, oral microbiota collection and Questionnaires in people with Hyperphagia, run by Rennes University Hospital at 1 site in France.
Trial summary
Emotional overeating is characterized by an excessive food intake in the context of intense emotional situations, such as acute stress one. Emotional overeating, as a behavioral trait, can increase the risk of to develop eating disorders or eating-related diseases, such as metabolic syndrome, obesity, type-2 diabetes.

About this study
Emotional overeating is characterized by an excessive food intake in the context of intense emotional situations, such as acute stress one. Emotional overeating, as a behavioral trait, can increase the risk of to develop eating disorders or eating-related diseases, such as metabolic syndrome, obesity, type-2 diabetes. Recently, imaging modalities, such as magnetic resonance imaging (MRI) and electro-encephalography (EEG), have been adapted in order to perform neurofeedback consisting on presenting the brain activity instantaneously to the participant, that give him the possibility to modify this activity by his own mean. Neurofeedback has already shown some efficacy, either with explicit or implicit instruction.
Compared with functional MRI (fMRI), functional near infra-red spectroscopy (fNIRS) is easy to handle, less expensive, and does not require a lying position. fNIRS is consequently more adapted for repeated acquisitions. Neurofeedback has already shown some promising results for neurological and psychiatric diseases. For mental states and emotion regulation, neurofeedback targeting the prefrontal cortex (PFC) has also shown promising outcomes. In this project, the investigators want to assess the effect of neurofeedback targeting the dorsolateral PFC (dlPFC) in a population of young adult women presenting emotional overeating. The investigators aim to improve the cognitive control and to reduce the episodes of emotional overeating in order to prevent the occurrence of subsequent pathologies.

The intervention effect will be characterized with: (i) fMRI in order to evaluate the effect on cognitive control (with resting state fMRI or rsMRI) and on the reward system; (II) questionaries directly and one month after intervention in order to assess the behavioral effect.
Besides an expected effect on emotional overeating, the investigators will evaluate whether an improvement of cognitive control can also promote positive effect on other behavioral traits that could lead to some pathologies such as food addiction.
As a prerequisite to this study on emotional overeating (study B), the investigators will firstly validate on healthy subjects (study A) a reward anticipation fMRI task, which will be further used in study A in order to characterized the effect of neurofeedback on the reward system.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Neurofeedback with functional near infra-red spectroscopyDevice
the neurofeedback protocol will last 15 minutes per session, and during each session, the volunteer will have to increase the brain activity of his/her dorsolateral prefrontal cortex using a visual gauge representing the "activity level" of his/her own dorsolateral prefrontal cortex. No specific instructions will be given to the volunteer so that he/she can develop his/her own internal strategy to increase this "activity level".
Sham NeurofeedbackDevice
the participants will receive the same instruction but will be shown a random signal
oral microbiota collectionOther
an examination and oral swab for oral microbiota analysis will be performed by a dentist
QuestionnairesOther
questionnaires for pre-intervention behavioral characterization
resting-state fMRIDevice
characterize the brain function of volunteers by resting-state fMRI
Electro gastrogramDevice
Volunteers will also be equipped with an MRI-compatible electro-gastrogram device to correlate gastric signals with brain activity during rsMRI acquisition.

Questions about this trial
What is this clinical trial studying?
A study testing Neurofeedback with functional near infra-red spectroscopy, oral microbiota collection and Questionnaires in people with Hyperphagia, run by Rennes University Hospital at 1 site in France.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 9 inclusion and 31 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 28 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Loïc JACOB (0299282555, loic.jacob@chu-rennes.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in cortico-striatal connectivity (time frame: 4 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Sep 2026.
