Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Recent scientific data suggest that eating disorders, leading to weight gain and obesity, will be similar of those of drug addiction: it is the incentive sensitization theory that implicates the dopaminergic reward system.
The aim of this cross-sectional study is to investigate the alteration of P300 auditory ERP in obese women with eating disorders in comparison with obese and lean women without eating disorders.
