摘要
Bulimia nervosa (BN) is a disabling eating disorder that is associated with costly medical morbidity and often follows a chronic course. Novel treatments are needed, particularly those that directly target symptom-maintaining mechanisms. One such mechanism may be reduced activation of the prefrontal cortex (PFC) during attempts to control behavioral responses. In this proof-of-principle project, we propose to develop, establish feasibility, and preliminarily test a novel neurofeedback procedure that is intended to increase PFC activation and enhance the ability to control the consumption of common binge foods. We will compare the effects of one session of real and sham neurofeedback during eating on neural activation, inhibitory control, and clinical symptoms in women with BN. To our knowledge, this will be the first test of neurofeedback in BN to date. Results will establish this new technique’s potential to clarify causal mechanisms of BN symptoms and inform future clinical trials. Trial Registration: NCT05614024.
