The question of the image of the body does not have the same implications in neurosis and in psychosis. In clinical practice, we are able to observe that eating addictions are often linked to a narcissistic problematic. But is this valid for all clinical structures? Using clinical cases, we seek to show the difference in the function of addictions in neurosis and psychosis. This allows us to point out a distinction that has to be taken into account in the direction of the treatment.
