Neurofeedback Based on Near-infrared Spectroscopy as a Therapy for Food Addiction in Obese Subjects.
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
Inclusion: Eligible for obesity surgery according to the 2009 French High Authority on Health (HAS) criteria (BMI ≥40 or BMI ≥35 with comorbidities); Right-handed; Presenting a food addiction determined by the YFAS 2.0 questionnaire ; Affiliated to a social security system; Having given free and informed consent in writing.
Exclusion: Psychotropic drugs, except antidepressants stabilized for at least 3 weeks and benzodiazepines; Psychotic psychiatric disorders (schizophrenic disorders and bipolar disorders); History of bariatric surgery; Persons of legal age under legal protection (safeguard of justice, curatorship, guardianship), persons deprived of liberty; Addiction to alcohol or other psychoactive substances (except tobacco); Current treatment in the nutrition unit; Insufficient command of French; Pregnant or breast-feeding woman; Contraindications to fMRI; Inability to perform the fNIRS procedure due to blockage or attenuation of the light at the capillary level.
