“…Evidence from cognitive tasks support deficits in executive functions (EFs), or a set of cognitive processes that support higher order cognitive abilities and goal attainment [29], in both children with obesity [30] and disordered eating [31]. Children with comorbid obesity and dysfunctional eating may have a cognitive profile that is distinct and more deficient then youth with obesity alone [32, 33].…”

Purpose of the Review: Children with obesity experience disordered eating attitudes and behaviors at high rates, which increases their risk for adult obesity and eating disorder development. As such, it is imperative to screen for disordered eating symptoms and identify appropriate treatments. Recent findings: Family-based multicomponent behavioral weight loss treatment (FBT) is effective at treating childhood obesity and demonstrates positive outcomes on psychosocial outcomes, including disordered eating. FBT utilizes a socio-ecological treatment approach that focuses on the development of individual and family healthy energy balance behaviors as well as positive self- and body-esteem, supportive family relationships, richer social networks, and the creation of a broader environment and community that facilitates overall physical and mental health. Summary: Existing literature suggests FBT is an effective treatment option for disordered eating and obesity in children. Future work is needed to confirm this conclusion and to examine the progression and interaction of obesity and disordered eating across development to understand the time for optimal intervention.

“…Additionally, poor inhibitory control (i.e., the ability to inhibit a prepotent response) has been observed in EDs characterized by binge eating (Fischer, Smith, & Anderson, 2003; Rosval et al, 2006; Wu et al, 2013). Converging evidence that deficits in EF are present in adolescents who have a short duration of ED illness (Darcy et al, 2012, 2014; Fitzpatrick et al, 2012), and that deficits remain following symptom remission (Holliday et al, 2005; Lopez et al, 2009; Roberts et al, 2007, 2010), suggest that these traits could be causal rather than consequential (though there is likely to be some degree of bi-directionality) (Kanakam & Treasure, 2013). …”

Current gold standard treatments for eating disorders (EDs) lack satisfactory efficacy, and traditional psychological treatments do not directly address executive functioning deficits underpinning ED pathology. The goal of this paper is to explore the potential for enhancing ED treatment outcomes by improving executive functioning deficits that have been demonstrated to underlie eating pathology. To achieve our objective, we (1) review existing evidence for executive functioning deficits that underpin EDs and consider the extent to which these deficits could be targeted in neurocognitive training programs, (2) present the evidence for the one ED neurocognitive training program well-studied to date (Cognitive Remediation Therapy), (3) discuss the utility of neurocognitive training programs that have been developed for other psychiatric disorders with similar deficits, and (4) provide suggestions for the future development and research of neurocognitive training programs for EDs. Despite the fact that the body of empirical work on neurocognitive training programs for eating disorders is very small, we conclude that their potential is high given the combined evidence for the role of deficits in executive functioning in EDs, the initial promise of Cognitive Remediation Training, and the success in treating related conditions with neurocognitive training. Based on the evidence to date, it appears that the development and empirical evaluation of neurocognitive training programs for EDs is warranted.

“…Although there is less research, studies with individuals with Bulimia Nervosa (BN) have also demonstrated poor global processing in comparison to healthy controls (HCs); suggesting that this processing style is a trans-diagnostic characteristic amongst EDs [9,12,13]. …”

Central Coherence in Eating Disorders: A Synthesis of Studies Using the Rey Osterrieth Complex Figure Test

et al. 2016

BackgroundLarge variability in tests and differences in scoring systems used to study central coherence in eating disorders may lead to different interpretations, inconsistent findings and between study discrepancies. This study aimed to address inconsistencies by collating data from several studies from the same research group that used the Rey Osterrieth Complex Figure Test (Rey Figure) in order to produce norms to provide benchmark data for future studies.MethodData was collated from 984 participants in total. Anorexia Nervosa, Bulimia Nervosa, recovered Anorexia Nervosa, unaffected family members and healthy controls were compared using the Rey Figure.ResultsPoor global processing was observed across all current eating disorder sub-groups and in unaffected relatives. There was no difference in performance between recovered AN and HC groups.ConclusionsThis is the largest dataset reported in the literature and supports previous studies implicating poor global processing across eating disorders using the Rey Figure. It provides robust normative data useful for future studies.
