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

The present study provides evidence for reduction of P300 and N200 amplitude in obese women and that N200 amplitude may be related to more disordered eating and eating disorder risk. This leads to consider attentional bias and response inhibition as core mechanisms in obesity and as possible targets for new therapeutic strategy.
