Neurofeedback Based on Near-infrared Spectroscopy as a Therapy for Food Addiction in Obese Subjects.

NCT05277714 · Status: RECRUITING · Phase: NA · Type: INTERVENTIONAL · Enrollment: 50

Last updated 2025-08-08

No results posted yet for this study

Summary

The hypothesis is that the increase in dlPFC brain activity via near-infrared spectroscopy-based Neurofeedback (fNIRS-based NF) training based on near-infrared spectroscopy would allow an improvement of the eating behavior, thus promoting a long-term weight loss in obese subjects.

Patients will be trained during a month with 8 NF sessions and results based on clinical data and different questionnaires results will be compared between inclusion and 3 months later

Conditions

Interventions

OTHER

Sham

The sham protocol will last 15 minutes per session, and during each session, the participants will receive the same instruction but will be shown a random signal, the goal being that the control strategy that the participant tries to implement is not correlated with the visual feedback provided by the gauge.

OTHER

NF

The neurofeedback protocol will be the same during the 8 sessions constituting the protocol and taking place over a period of 4 weeks (2 neurofeedback sessions per week, the first and the last one in an MRI context). It will last 15 minutes per session, and during each session, the patient will have to increase the brain activity of her dlPFC using a visual gauge representing the "activity level" of her own dlPFC. 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".
