Attentional bias and response inhibition in severe obesity with food disinhibition: a study of P300 and N200 event-related potential

Background/Objective In obesity there is growing evidence for common mechanism between food intake regulation and substance use disorders, especially more attentional bias and less cognitive control. In the present study we investigated whether severely obese subjects with or without disordered eati...

Description
Summary:Background/Objective In obesity there is growing evidence for common mechanism between food intake regulation and substance use disorders, especially more attentional bias and less cognitive control. In the present study we investigated whether severely obese subjects with or without disordered eating exhibit electroencephalographic (EEG) event-related potential (ERP) modifications as observed in substance abusers. Subjects/Methods A total of 90 women were included; 30 in the normal-weight (NW) group (18.5
