Summary

Body Image distortion is a key diagnostic feature for Anorexia Nervosa. Patients suffering from Anorexia Nervosa tend to perceive themselves as fatter than they are. This bias might be at the origin of a reinforcement of anorectic behavior which might alter medical care. The objective of this study is to identify neural correlates of self-recognition in Anorexia Nervosa. Patients are hypothesized to activate the self-recognition network when seeing images of a fatter body shape than their own.

Detailed description

Patients suffering from Anorexia Nervosa and control subjects (matched by age and study level) are recruited in medical care facilities in Lille's Metropolis. They are asked to identify their body shape when being presented with 3 different stimuli, i.e.real (RBS), estimated (EBS) and neutral body shape (NBS), in a functional magnetic resonance imaging or functional MRI (fMRI) machine. While answering to this identification paradigm, we hoped to identify modifications in the self body-recognition network.
