OBJECTIVES: Obsessive-compulsive personality disorder (OCDP) traits are commonly associated with eating disorders (EDs), with evidence demonstrating that these traits predispose and exacerbate the ED illness course. However, limited research has examined the symptomatic interplay between ED and OCDP traits. We used network analysis to (1) identify the most central symptoms in a network comprised of OCPD traits retrospectively assessed in childhood and ED symptoms and (2) to identify symptoms...

Though cognitive behavioural therapy would seem to offer good results, there is still no resounding evidence pointing to a single treatment of choice. The case presented in this paper examines the treatment with CBT of a patient presenting anorexia nervosa.

The authors concluded that set-shifting difficulties problems were predictive of features of anorexia nervosa. An alternative interpretation is that set shifting is predictive of large weight changes and eating behaviors...

PURPOSE OF REVIEW: Abnormal interoception has been consistently observed across eating disorders despite limited inclusion in diagnostic conceptualization. Using the alimentary tract as well as recent developments in interoceptive neuroscience and predictive processing as a guide, the current review summarizes evidence of gastrointestinal interoceptive dysfunction in eating disorders.
