This randomized controlled trial investigates the efficacy of functional near-infrared spectroscopy (fNIRS)-based neurofeedback in enhancing inhibitory cognitive control among 50 females with severe obesity and food addiction. Participants will undergo eight neurofeedback sessions, with outcomes assessed through neuroimaging and clinical measures. The primary endpoint focuses on changes in cognitive control, specifically variations in cortico-striatal resting-state functional connectivity.
Key findings
- Participants will be randomly assigned to either the neurofeedback group or a sham control group.
- The intervention consists of eight fNIRS-based neurofeedback sessions over one month.
- Primary endpoint includes changes in cognitive control assessed by variations in cortico-striatal resting-state functional connectivity.
Why it matters
Understanding the impact of neurofeedback on cognitive control in patients with obesity and food addiction could provide new therapeutic strategies. Enhancing inhibitory control may help in managing eating behaviors and contribute to obesity treatment and prevention.
