Anorexia nervosa (AN) is a frequent, potentially life-threatening eating disorder characterized by a resistance to maintaining body weight at or above a minimally normal weight for age and height, an intense fear of weight gain or being "fat" even though underweight, a loss of menstrual periods in girls and women post-puberty and a disturbance in the experience of body weight or shape. Body weight and shape dissatisfaction is linked to the development, maintenance and relapse of AN. Neuroimaging studies have shown that the inferior parietal cortex is involved in body image perception and less activated in patients with AN compared with healthy subjects. Repetitive transcranial magnetic stimulation (rTMS) is used to modulate cortical excitability, and particularly to increase excitability with high-frequency rTMS. The aim of this study was to investigate the effect of "excitatory" high-frequency rTMS over the "hypoactive" inferior parietal cortex of 54 patients with AN.
