Changes in self-regulation-related prefrontal activities in eating disorders: a near infrared spectroscopy study.

<h4>Objective</h4>The aim of this study is to clarify the symptomatology of the eating disorders examining the prefrontal function and activity associated with self-regulation among participants with or without eating disorders.<h4>Methods</h4>Ten patients with anorexia nervo...

The psychiatric symptoms of patient groups were assessed with several questionnaires.<h4>Results</h4>Patients with bulimia nervosa showed decreased performances and prefrontal hyper activation patterns. Prefrontal activities showed a moderate negative correlation with task performances not in the patient groups but only in the healthy participants.
