Marchesi G, Cammisuli DM, Semonella M, Castelnuovo G, Pietrabissa G. The Efficacy of Cognitive Remediation Therapy for Anorexia Nervosa: A Systematic Review of Systematic Reviews. Brain Sci 2024; 14:118. [PMID: 38391693 PMCID: PMC10886621 DOI: 10.3390/brainsci14020118] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2023] [Revised: 01/16/2024] [Accepted: 01/20/2024] [Indexed: 02/24/2024] Open
Abstract
BACKGROUND Cognitive remediation therapy (CRT) for anorexia nervosa (AN) is an intervention specifically focused on addressing cognitive difficulties associated with the eating disorder. This systematic review of systematic reviews and meta-analysis aimed to provide a summary of the existing literature examining the efficacy of CRT in improving the neuropsychological, psychological, and clinical parameters of patients with AN. METHODS Systematic reviews and meta-analyses were sought in electronic databases, encompassing studies that explored the impact of CRT on AN. Three eligible reviews were identified based on the inclusion criteria. The Revised Assessment of Multiple SysTemAtic Reviews (R-AMSTAR) was employed to evaluate the methodological quality of the reviews, and all included reviews demonstrated satisfactory methodological quality with an R-AMSTAR score of ≥22. Relevant information was extracted from each review and qualitatively compiled. RESULTS Findings suggest that CRT can help people increase their awareness of cognitive styles and information processing and have a positive effect on patients' responses to treatment. CONCLUSIONS Further research is required to better understand its impact on other relevant outcomes, including psychological variables, to optimize the treatment's benefits.

Cognitive flexibility and DSM-5 severity criteria for eating disorders: assessing drive for thinness and duration of illness as alternative severity variables. J Eat Disord 2023; 11:155. [PMID: 37697328 PMCID: PMC10496406 DOI: 10.1186/s40337-023-00875-z] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/27/2023] [Accepted: 08/22/2023] [Indexed: 09/13/2023] Open
Abstract
BACKGROUND The severity criteria for eating disorders (EDs) proposed in the DSM-5 have been established without sufficient empirical support. Drive for thinness (DT) and duration of illness have been proposed as two alternative severity measures, however their empirical evidence is also limited. To date, no research has assessed the validity of current eating disorder (ED) severity criteria regarding cognitive flexibility factors. Cognitive flexibility is often impaired in EDs, becoming a possible severity symptom. The current study assessed for the first time (1) whether the severity indexes for EDs proposed in the DSM-5 were associated with deficits in cognitive flexibility and, (2) whether drive for thinness and illness duration, acted as an alternative, more meaningful severity indices for deficiencies in cognitive flexibility. METHODS Participants were 161 patients diagnosed with an ED, who were categorized according to DSM-5 severity categories, DT and duration of illness. Discriminative capacity of each classification was assessed for cognitive flexibility measured by Wisconsin card sorting test (WCST). RESULTS The findings for the DSM-5 classification comprised: (a) In the anorexia nervosa (AN) group, patients with moderate severity showed better scores in WCST than patients with mild and severe/extreme severity. Also, patients with moderate severity showed lower percentage of cognitive flexibility deficits than the other two severity categories; (b) For the binge spectrum disorders (BSD) group, the patients with mild severity showed a higher percentage of cognitive flexibility deficits than did the moderate and severe/extreme categories. When assessing the alternative severity index of DT, no differences were found in cognitive flexibility in any of the groups. Regarding illness duration, in the AN group the task performance of the patients with longer illness duration was worse than the performance of the short duration group and, in the BSD group, patients with longer duration also showed more deficits in cognitive flexibility than the patients with shorter duration of illness. CONCLUSIONS Our findings point out the limitations of the DSM-5 severity criteria to categorize cognitive flexibility in EDs and support illness duration as an alternative severity approach for EDs.

Chang YS, Liao FT, Huang LC, Chen SL. The Treatment Experience of Anorexia Nervosa in Adolescents from Healthcare Professionals' Perspective: A Qualitative Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:794. [PMID: 36613116 PMCID: PMC9819642 DOI: 10.3390/ijerph20010794] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/31/2022] [Revised: 10/03/2022] [Accepted: 10/03/2022] [Indexed: 06/17/2023]
Abstract
Anorexia nervosa (AN) is a serious psychiatric illness with a high mortality rate and a poor outcome. AN in adolescents can be difficult to treat. The prognosis of patients with AN depends highly on how early specialized AN treatment starts. Therefore, the purpose of this study was to explore the experiences of healthcare professionals in treating adolescents with AN. A qualitative study approach was conducted. Through semi-structured interviews, 16 healthcare professionals, including 10 nurses, 3 dieticians and 3 physicians from the paediatric ward at a university-affiliated medical centre in central Taiwan, shared their experiences. Recorded interviews were transcribed and analyzed by content analysis. Five themes and ten subthemes were identified: 1. Building a trusting relationship first: (a) spending time to build trust with the client and (b) establishing a relationship with the client's parents; 2. The key to treatment success: (a) Clients' awareness of the illness and (b) parents' support for clients; 3. Consistency of team treatment goals: (a) maintaining stable vital signs and (b) achieving caloric intake; 4. Empowerment with knowledge about anorexia: (a) continuing education for healthcare professionals and (b) interdisciplinary collaborative care; and 5. Using different interaction strategies: (a) the hard approach and (b) the soft approach. In conclusion, the findings will provide important information for healthcare professionals to apply in monitoring the psychological and emotional states of adolescents with AN. The findings indicate that healthcare professionals should invite parents to participate in the treatment, support and guide them in their adolescent care, develop scales of family stress and support for AN in adolescents, develop interventions, and establish an early therapeutic alliance.

Group cognitive remediation therapy for children and adolescents in intensive day-patient treatment for anorexia nervosa: a feasibility study. NEUROPSYCHIATRIE 2022; 36:125-135. [PMID: 35704173 PMCID: PMC9458577 DOI: 10.1007/s40211-022-00420-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/05/2021] [Accepted: 05/10/2022] [Indexed: 11/20/2022]
Abstract
Background Cognitive Remediation Therapy (CRT) is an adjunct treatment targeting set-shifting (SS) and weak central coherence (CC) thought to play a role in maintaining anorexia nervosa (AN). This study aimed to test the feasibility of brief group CRT for young people with AN in a day-patient setting using neuropsychological assessment of SS and CC. It also explored the benefit for young people with Autism Spectrum Disorder (ASD) features. Methods Twenty female day-patients (12–18 years) with AN or Atypical AN completed neuropsychological assessment of SS (using the Wisconsin Card Sorting Task and the Brixton Spatial Anticipation Test) and of CC (using the Rey Osterrieth Complex Figures Task) pre and post 4 sessions of group CRT. Baseline ASD features and weight change pre and post were measured. Feasibility was assessed regarding the recruitment process, intervention feedback, suitability of neuropsychological assessment measures, and effect sizes. Results Study uptake was 95%, intervention retention was 91%, and group CRT was rated as acceptable. Medium to large effect size improvements were found across measures of SS (dz = 0.44 to dz = 0.90) and medium size improvements found in CC (dz = 0.59). Young people with ASD features showed smaller to similar size improvements in SS and larger improvements in CC. There was a moderate (not significant) correlation with level of weight restoration. Conclusions Important study parameters have been estimated in order to plan a future definitive trial of brief group CRT in a day-patient setting using neuropsychological assessment. These findings also have implications for the use of brief group CRT in young people with ASD features.

Abstract
Despite bariatric surgery being the most effective treatment for obesity, some individuals do not respond adequately, especially in the long term. Identifying the predictors of correct weight maintenance in the medium (from 1 to 3 years after surgery) and long term (from 3 years and above) is of vital importance to reduce failure after bariatric surgery; therefore, we summarize the evidence about certain factors, among which we highlight surgical technique, psychological factors, physical activity, adherence to diet, gastrointestinal hormones or neurological factors related to appetite control. We conducted a search in PubMed focused on the last five years (2015–2021). Main findings are as follows: despite Roux-en-Y gastric bypass being more effective in the long term, sleeve gastrectomy shows a more beneficial effectiveness–complications balance; pre-surgical psychological and behavioral evaluation along with post-surgical treatment improve long-term surgical outcomes; physical activity programs after bariatric surgery, in addition to continuous and comprehensive care interventions regarding diet habits, improve weight loss maintenance, but it is necessary to improve adherence; the impact of bariatric surgery on the gut–brain axis seems to influence weight maintenance. In conclusion, although interesting findings exist, the evidence is contradictory in some places, and long-term clinical trials are necessary to draw more robust conclusions.

Abstract
OBJECTIVE Poor cognitive flexibility has been highlighted in patients with anorexia nervosa (AN), contributing to the development and maintenance of symptoms. The aim of the present study is to investigate how enhanced cognitive flexibility is involved in treatment outcomes in patients with AN. METHOD One hundred thirty female out-patients treated for AN have been assessed at baseline and after 4 months of treatment. Path analyses were used to investigate the mediating role of cognitive flexibility, measured through the Brixton test, on a wide range of outcomes: body mass index, eating disorder symptoms, daily life functioning, anxiety, depression, emotions, self-rated silhouette. RESULTS Cognitive flexibility was improved during treatment, and enhanced cognitive flexibility explains a significant part of level of the improvement in daily life functioning (26%), reduction of eating disorder symptoms (18%) and reduction of depressive symptoms (17%). Others outcomes were also improved, but these improvements were not mediated by cognitive flexibility. CONCLUSIONS Results suggest that enhancing cognitive flexibility could help reduce rigid cognitive and behavioural patterns involved in AN, thus improving everyday functioning and clinical severity. Further studies combining different types of cognitive flexibility evaluation as well as neuroimaging may be necessary to better establish which of its aspects are involved in patients' improvement.

The shifting perspectives study protocol: Cognitive remediation therapy as an adjunctive treatment to family based treatment for adolescents with anorexia nervosa. Contemp Clin Trials 2021; 103:106313.

Abstract
BACKGROUND Adolescents with anorexia nervosa have set-shifting inefficiencies that can be exacerbated by starvation and that may interfere with outcomes of treatment interventions. Cognitive Remediation Therapy (CRT), an adjunctive treatment focused on improving set-shifting, can target inefficiencies and may augment treatment effectiveness. The best way to add CRT to the standard of care (Family Based Treatment, FBT) for adolescents with anorexia remains understudied. METHODS/DESIGN This is a randomized controlled trial designed to determine if CRT is effective in increasing flexibility in adolescents with anorexia and/or their parents. Participants are adolescents 12-18 years old with anorexia and their parents. 54 family groups will be randomized into one of three groups: FBT only, FBT plus Parent-focused CRT, or FBT plus Adolescent-focused CRT. Psychosocial, neurocognitive, and behavioral measures will be collected throughout the study. DISCUSSION This is the first study of its kind to apply CRT to parents. All forms of CRT in the context of anorexia have targeted the individual with anorexia's thinking style. We propose that it may be impactful to target the parent of the adolescent with anorexia as parents carry the burden of treatment and re-nourishment of their child during FBT and may have similar thinking styles. CONCLUSION This study takes an experimental therapeutics approach to further our understanding of the mechanisms of treatment for adolescents with anorexia. It focuses on increasing cognitive flexibility in patients or their parents and determining the appropriate dose of CRT needed to achieve positive change.

Abstract
Autistic traits or autism spectrum disorder (ASD) can be found in 4% to 52% of anorexic patients, which makes the treatment of these patients very challenging. In this review, possible ways to treat ASD and anorexia nervosa (AN) comorbidity in children and adolescents are summarized. Over recent years, the focus has shifted from searching for the evidence of connections between these two disorders, which have started with Gillberg's study in 1983, to searching for more effective and holistic treatment of this comorbidity. The latter is known to contribute to more severe courses and worse prognosis, which is probably related to the obstacles in both diagnosing and treating. Since AN usually starts in early adolescence and high-functioning ASD children seem to begin struggling with increased pressure in adolescence, while various comorbidities can occur, it is important to improve the treatment of this comorbidity in young patients and to tailor it specifically in terms of diagnosing. In this paper, a literature review is conducted on common features and promising treatment possibilities. We describe cognitive remediation therapy and the promising pharmacotherapeutic candidate oxytocin with a special focus on adolescents.

Abstract
For many sufferers of anorexia nervosa, the time course is long, and the prospect of disability and family burden great. This is all too often the case, even with early diagnosis and treatment. The term severe and enduring anorexia nervosa has been applied to these survivors. Yet, a majority of patients do eventually recover and, even where this is not the case, adaptive medical stability and function can be maintained despite alarming dilapidation. Managing the years of illness so as to have the best outcome physically and psychologically, even where full weight recovery does not occur, or has not yet occurred, is the topic of this article. Literature pertaining to harm minimization in chronic, severe, enduring, and long-standing anorexia nervosa was selectively reviewed using an Ovid data base and Google Scholar. The authors' own clinical experience over almost four decades in public and private hospital and community settings has also informed much of what has been written. The authors would like to think that it is possible to do better than the familiar injunction (variously attributed to Hippocrates, Galen, and others) of 'primum non nocere'-although this is a good place to start.

Abstract
Cognitive remediation therapy (CRT) is a low-intensity treatment adjunct for individuals with severe and complex anorexia nervosa (AN) with difficulties in globally oriented, flexible thinking. Previously trialled in adults, this study investigated whether individual and group CRT was a feasible, acceptable, and beneficial treatment for 125 adolescent inpatients with severe and complex AN. Seventy patients (mean age = 15.22, SD = 1.44) received 10 sessions of individual CRT, and 55 patients (mean age = 14.89, SD = 1.74) received 10 sessions of group CRT. In individual CRT, 1 patient (1.43%) dropped out, and there were medium-sized improvements in bigger picture thinking and set-shifting, small to large-sized improvements in switching-related initiation and inhibition skills, and large-sized improvements in motivation to recover. Group CRT had higher dropout (9.09%; n = 5) and produced small-sized improvements in global information processing and medium-sized improvements in self-reported cognitive flexibility and high acceptability ratings. Data suggest that a randomised controlled trial for adolescents with AN is warranted.

Abstract
PURPOSE Research suggests that there are cognitive inefficiencies underlying Anorexia Nervosa (AN), with CRT showing promise in improving these inefficiencies in adults. This area has yet to be explored in a younger population. The aim of this study was to evaluate the use of CRT for young people. METHODS A within-subjects design was used to compare the performance of children and adolescents with AN on several neuropsychological measures administered before and after a course of CRT. RESULTS Ninety-two female participants diagnosed with AN aged between 11 and 17 (M = 14.8, SD = 1.6), all receiving treatment at a specialist inpatient unit. The assessment consisted of the Rey-Osterrieth Complex Figure test (ROCFT), the Behaviour Rating Inventory of Executive Function-Self-Report (BRIEF-SR), and the D-KEFS Colour-Word Interference Test (CWT). Repeated-measures t tests were used to analyse the ROCFT and BRIEF-SR data. There was a significant improvement in Central Coherence Index (p < .001), Immediate Recall (p < .001), Shift (p < .001) Cognitive Shift (p = 002), Behavioural shift (p < .001), Emotional Control (p < .001), Working Memory (p = .001), Plan/Organize (p < .001), Monitor (p = .001) BRI (p < .001), MI (p = .001), and GEC (p < .001). On the D-KEFS CWT, a repeated-measure Wilcoxon signed-rank test revealed a significant improvement in Error Rate (p = .019) and a repeated-measures t test revealed a significant improvement in time taken (p < .001). CONCLUSIONS Results suggest that CRT for children and adolescents with AN could strengthen specific cognitive domains.

Abstract
Hilde Bruch's foundation lecture in 1982 is a milestone from which to survey current theory and treatment for anorexia nervosa. Bruch described problems in body perception, emotion processing and interpersonal relationships as core theoretical aspects of the illness and built her theory of psychopathology on these aspects, as well as on animal studies on attachment. She also noted that many psychological problems result as consequence of starvation. In the first part of this paper, we parse Bruch's clinical descriptions into elements of psychopathology (disturbances in body perception, attachment, emotion expression, perception and regulation, social comparison, interpersonal, and family and therapeutic relationships), in order to assemble and update the theoretical evidence for a model of the illness. In the second part, we describe and extend her description of three core targets of treatment: family relationships, patient's inner confusion and nutritional restoration.

Abstract
OBJECTIVE Research investigating the link between eating disorder (ED) diagnosis and executive dysfunction has had conflicting results, yet no meta-analyses have examined the overall association of ED pathology with executive functioning (EF). METHOD Effect sizes were extracted from 32 studies comparing ED groups (27 of anorexia nervosa, 9 of bulimia nervosa) with controls to determine the grand mean effect on EF. Analyses included effects for individual EF measures, as well as an age-based subgroup analysis. RESULTS There was a medium effect of ED diagnosis on executive functioning, with bulimia nervosa demonstrating a larger effect (Hedges's g=-0.70) than anorexia nervosa (g=-0.41). Within anorexia nervosa studies, subgroup analyses were conducted for age and diagnostic subtype. The effect of anorexia nervosa on EF was largest in adults; however, subgroup differences for age were not significant. CONCLUSIONS Anorexia and bulimia nervosa are associated with EF deficits, which are particularly notable for individuals with bulimia nervosa. The present analysis includes recommendations for future studies regarding study design and EF measurement.

Abstract
BACKGROUND Set-shifting (SS) difficulties and weak central coherence (CC) are commonly associated with autism spectrum disorders (ASD). Cognitive remediation therapy (CRT) aims to improve such cognitive processing; however, there are no reports on CRT for patients with ASD. This pilot study aimed to provide preliminary evidence to support the use of CRT for individuals with ASD and provide data to inform future studies. PARTICIPANTS AND METHODS Nineteen individuals with ASD were recruited and administered a series of neuropsychological and questionnaire measures to examine cognitive function and clinical outcomes such as anxiety and depression. Participants received CRT, and cognitive function and clinical variables were re-evaluated at postintervention and after 3 months. RESULTS The participants demonstrated significant improvement in CC and anxiety at postintervention, which was maintained at 3-month follow-up. Although SS scores had improved with a large effect size, this was not statistically significant. CONCLUSION CRT improved CC and anxiety scores for individuals with ASD, suggesting that CRT is an effective treatment for individuals with ASD.

Abstract
PURPOSE The present review explores emotion-focused treatments for anorexia nervosa (AN). METHODS We conducted a systematic literature search across key databases (PsychINFO, PubMed/Medline, and Web of Science) prior to September 2015. Twenty studies were selected for systematic review. RESULTS The present review found initial evidence supporting the acceptability and feasibility of emotion-focused treatments for AN. Although preliminary results are promising, further controlled studies are necessary to establish the efficacy of emotion-focused treatments for AN. CONCLUSIONS Future controlled trials should compare emotion-focused treatments against each other and against other AN treatments. Future studies should also examine the mechanisms of action for the emotion-focused treatments and treatment moderators.

Abstract
PURPOSE OF REVIEW This review compares the literature on cognitive remediation therapy (CRT) for eating disorders with findings in the field of schizophrenia, and discusses future directions for CRT for eating disorders. RECENT FINDINGS First studies using a randomized controlled trial design show the added value of CRT for eating disorders. Patients reported lessened symptoms and further improvements in quality of life and cognitive flexibility. Furthermore, the acceptability of the intervention was good and attrition rates for CRT itself were low. Research into the use of cognitive remediation for schizophrenia is extensive and the results on global cognition appeared to be robust at post-treatment and durable at follow-up, with small to medium effect sizes. Recent articles within the field of schizophrenia emphasize the necessity of intrinsic motivation to translate cognitive gains into actual changes in everyday life. SUMMARY A next step is to examine the impact of CRT for eating disorders on motivation. It is also important to focus on the transdiagnostic use of CRT, considering the overlap in cognitive inefficiencies between eating disorders. Another important step may be to develop effective personalized methods of CRT by taking into account individual differences in cognitive processes most relevant to improvement in outcome.

Abstract
BACKGROUND Anorexia nervosa is a disorder with high morbidity and significant mortality. It is most common in young adult women, in whom the incidence may be increasing. The focus of treatment has moved to an outpatient setting, and a number of differing psychological therapies are presently used in treatment. This is an update of a Cochrane review which was last published in 2008. OBJECTIVES To assess the effects of specific individual psychological therapies for anorexia nervosa in adults or older adolescents treated in an outpatient setting. SEARCH METHODS We searched the Cochrane Depression, Anxiety and Neurosis Review Group Specialised Register (CCDANCTR) (16 July 2014). This register includes relevant randomised controlled trials from: the Cochrane Library (all years), MEDLINE (1950 to date), EMBASE (1974 to date), and PsycINFO (1967 to date). We screened reference lists of all included studies and sent letters to identified, notable researchers requesting information on unpublished or ongoing studies. SELECTION CRITERIA All randomised controlled trials of one or more individual outpatient psychological therapies for adults with anorexia nervosa, as defined by DSM-5 or similar international criteria. DATA COLLECTION AND ANALYSIS We selected a range of outcome variables, including physical state, severity of eating disorder attitudes and beliefs, interpersonal function, and general psychiatric symptom severity. Continuous outcome data comparisons used the mean or standardised mean difference (MD or SMD), and binary outcome comparisons used the risk ratio (RR). Two review authors (PH and AC or ST) extracted data independently. MAIN RESULTS We identified 10 trials from the search, with a total of 599 anorexia nervosa participants, and included them in the review. Seven had been identified in the previous versions of this review and we now include three new trials. We now deem one previously identified ongoing trial to be ineligible, and six ongoing trials are new for this update. Two of the 10 trials included children. Trials tested diverse psychological therapies and comparability was poor. Risks of bias were mostly evident through lack of blinded outcome assessments (in 60% of studies) and incomplete data reporting (attrition bias).The results suggest that treatment as usual (TAU) when delivered by a non-eating-disorder specialist or similar may be less efficacious than focal psychodynamic therapy. This was suggested for a primary outcome of recovery by achievement of a good or intermediate outcome on the Morgan and Russell Scale (RR 0.70, 95% confidence interval (CI) 0.51 to 0.97; 1 RCT, 40 participants; very low-quality evidence). However there were no differences between cognitive analytic therapy and TAU for this outcome (RR 0.78, 95% CI 0.61 to 1.00; 2 RCTs, 71 participants; very low-quality evidence), nor for body mass index (BMI). There were no differences in overall dropout rates between individual psychological therapies and TAU.Two trials found a non-specific specialist therapy (Specialist Supportive Clinical Management) or an Optimised TAU delivered by therapists with eating disorder expertise was similar in outcomes to cognitive behaviour therapy (BMI MD -0.00, 95% CI -0.91 to 0.91; 197 participants, low-quality evidence). When comparing individual psychological therapies with each other, no specific treatment was consistently superior to any other specific approach. Dietary advice as a control arm had a 100% non-completion rate in one trial (35 participants). None of the trials identified any adverse effects. Insufficient power was problematic for the majority of trials. AUTHORS' CONCLUSIONS There was a suggestion in one trial that focal psychodynamic therapy might be superior to TAU, but this is in the context of TAU performing poorly. An alternative control condition of dietary advice alone appeared to be unacceptable, but again this is based on just one trial. Owing to the risk of bias and limitations of studies, notably small sample sizes, we can draw no specific conclusions about the effects of specific individual psychological therapies for anorexia nervosa in adults or older adolescents. Larger RCTs of longer treatment duration and follow-up are needed.

Abstract
Anorexia nervosa (AN) in childhood and adolescence has a poor prognosis. It is possible that this may in part be due to the fact that cognitive weaknesses that appear to be risk factors for its development and maintenance are not being targeted in treatment. Through its focus on these deficits, cognitive remediation therapy (CRT) has been shown to be a promising intervention for AN. Furthermore, family interventions are widely recommended for this patient population, but to date no studies have reported the use of CRT in a family setting. This paper presents a case series in which family-based CRT was a significant component of the management. It was well received by patients and their families and previously treatment resistant patients became more engaged with the entire treatment process. In addition, all patients receiving family-based CRT went on to make progress towards recovery. These initial clinical observations suggest family-based CRT is likely to be a useful addition to treatment for child and adolescent AN and justifies formal evaluation.

Abstract
BACKGROUND How executive functioning affects delayed verbal recall in AN has never been tested. We investigated the influence of speed of information processing (SIP) and inhibition on delayed verbal recall in females with AN. METHODS Measures of SIP and inhibition from 35 females with AN were analyzed using hierarchical multiple regression after controlling for age, depressive symptomatology and body mass index. Each predictor was evaluated using structure coefficients, common variance and dominance weights. RESULTS The combination of measures of SIP and inhibition accounted for almost 80% of the variance on the delayed recall of the story recall task. When the rest of the variables were partialled out, SIP and inhibition accounted for more than 50% of the variance. CONCLUSIONS As it occurs with visuospatial abilities in AN, basic cognitive abilities such as speed of information processing and cognitive inhibition may affect other cognitive functions such as delayed verbal memory regardless of immediate recall. These findings may help interpret performance on cognitive tests in future research.

Abstract
BACKGROUND In this meta-analysis we review the findings from neuropsychological studies on set-shifting in people with eating disorders (EDs) or overweight/obesity. METHOD Four databases (PubMed, PsycINFO, PSYNDEX and Web of Science) were searched for eligible studies. Effect sizes (ESs) were pooled using random-effects models. Moderator analyses were conducted for ED and overweight/obese subgroups, adult/adolescent samples and measures of set-shifting. RESULTS Sixty-four studies with a total of 1825 ED patients [1394 anorexia nervosa (AN), 376 bulimia nervosa (BN) and 55 binge eating disorder (BED)] and 10 studies with a total of 449 overweight/obese individuals were included. The meta-analysis revealed a small to medium ES for inefficient set-shifting across all three ED diagnoses (Hedges' g = -0.45). Subgroup analyses yielded small to medium ESs for each ED subtype (g = -0.44 for AN, -0.53 for BED, -0.50 for BN), which did not differ significantly. There was a medium ES for restricting type AN (ANR; g = -0.51) but no significant ES for binge/purge type AN (AN/BP; g = -0.18). A medium ES was found across obesity studies (g = -0.61). The ES across overweight studies was not significant (g = -0.07). Adult samples did not differ from adolescent samples in either ED or overweight/obesity studies. The different set-shifting measures were associated with largely varying ESs. CONCLUSIONS The meta-analysis provides strong support that inefficient set-shifting is a salient neuropsychological phenomenon across ED subtypes and obesity, but is less prominent in AN/BP and overweight. Compulsivity seems to be a common underlying factor supporting a dimensional and transdiagnostic conceptualization of EDs and obesity.

Abstract
OBJECTIVES A bias towards local information over the global "gist" (weak central coherence, WCC), has been identified as a possible contributing and maintaining factor in eating disorders (ED). The present study aimed to provide an updated review of the WCC literature and examine the hypothesis that individuals with ED have WCC. METHODS The new search found 12 eligible studies. Meta-analyses were performed on nine of these 12 studies, the remaining three were commented on individually. Data were combined with data from the previous 2008 review, and meta- analyses were performed on 16 studies (nine studies from the new search and seven studies from 2008 review). RESULTS Meta-analysis of the Group Embedded Figures Task provided evidence of superior local processing across all ED subtypes (pooled effect size of d = -0.62 (95% CI = -0.94, -0.31), P < 0.001). Evidence of poorer global processing in ED groups was found from meta-analyses of the Rey-Osterrieth Complex Figures task (d = -0.63 (95% CI = -0.77, -0.49, P < 0.001), and the Object Assembly Task (d = -0.65 (95% CI = -0.94, -0.37), P < 0.0001). CONCLUSIONS As well as supporting the results of previous studies by providing evidence of inefficient global processing, this review has provided evidence of superior local processing, which supports the WCC hypothesis in ED.

Abstract
While evidence continues to accumulate on the relevance of cognitive inflexibility in anorexia nervosa (AN), its clinical correlates remain unclear. We aimed at examining the relationship between set-shifting and clinical variables (i.e., eating psychopathology, depression, and personality) in AN. Ninety-four individuals affected by AN and 59 healthy controls (HC) were recruited. All participants were assessed using: Eating Disorders Inventory-2 (EDI-2), Temperament and Character Inventory (TCI), Beck Depression Inventory (BDI), and Wisconsin Card Sorting Test (WCST). The AN group scored worse than HCs on set-shifting. According to their neuropsychological performances, AN patients were split into two groups corresponding to poor (N=30) and intact (N=64) set-shifting subtypes. Interoceptive awareness, impulse regulation, and maturity fears on the EDI-2 and depression on the BDI differed across all groups (HC, intact, and poor set-shifting subtype). Self-directedness on the TCI differed significantly among all groups. Cooperativeness and reward dependence differed instead only between HC and AN poor set-shifting subtype. After controlling for depression, only interoceptive awareness remained significant with reward dependence showing a trend towards statistical significance. These findings suggest that multiple clinical variables may be correlated with set-shifting performances in AN. The factors contributing to impaired cognitive inflexibility could be more complex than heretofore generally considered.

Abstract
Research evidence for cognitive remediation therapy's (CRT) effectiveness for anorexia nervosa (AN) has been gathering. This approach is also increasingly being implemented in other disorders including major depressive disorder, obsessive-compulsive disorder and autistic spectrum disorder that share commonalities with AN in neuropsychological profiles and clinical presentations. This systematic literature review identified and appraised the current evidence base to see whether evidence from related conditions could be integrated into the theoretical understanding of CRT for AN as well as future AN treatment developments and research. Overall, CRT studies in AN report promising findings, and CRT appears to be associated with improvements in set-shifting and in central coherence. Cognitive remediation approaches in other conditions also show promising evidence in associated improvements in areas of executive functioning and information processing; links are made between AN treatment and what future treatment developments could consider.

Abstract
BACKGROUND Individuals with eating disorders show deficits in neuropsychological functioning which might preexist and underlie the etiology of the eating disorders and influence relapse. Deficits in cognitive flexibility, i.e., set-shifting and central coherence, might perpetuate the symptoms. Cognitive remediation therapy (CRT) was developed to improve cognitive flexibility, thereby increasing the likelihood of improved outcome. The focus of CRT is on how patients think, rather than on what patients think. The present study investigated the effectiveness of CRT for patients with a severe or enduring eating disorder by means of a randomized controlled trial comparing intensive treatment as usual (TAU) to CRT plus TAU. METHODS Eighty-two patients were randomly assigned to CRT plus TAU (n = 41) or TAU alone (n = 41). Outcome measures were set-shifting, central coherence, eating disorder and general psychopathology, motivation, quality of life and self-esteem. Assessments were performed at baseline (n = 82) and after 6 weeks (T1; n = 75) and 6 months (T2; n = 67). Data were analyzed by means of linear mixed model analyses. RESULTS Patients who received CRT in addition to TAU improved significantly more with regard to eating disorder-related quality of life at the end of treatment (T1) and eating disorder psychopathology at follow-up (T2), compared to those who received TAU only. Moreover, moderator analyses revealed that patients with poor baseline set-shifting abilities benefited more from CRT than patients with no deficits in set-shifting abilities at baseline; the quality of life of the former group was higher than that of the latter at follow-up. CONCLUSIONS CRT seems to be promising in enhancing the effectiveness of concurrent treatment.

Abstract
BACKGROUND Cognitive Remediation Therapy (CRT) aims at improving neuropsychological weaknesses and associated thinking styles in patients with anorexia nervosa (AN). It has only recently been developed for adolescents with AN, and evidence of its applicability for this particular patient group is limited. This study aimed to test the feasibility of individually tailored and delivered CRT for young females with AN. METHODS A sample of 20 in- and outpatients (13-18 years) with AN participated in once- or twice weekly individual CRT sessions. The CRT materials used were available in a "CRT Resource Pack." Feasibility was assessed with regards to the recruitment process, the delivery of the intervention, the materials used and clinical experiences. RESULTS Overall results indicate that the intervention was feasible with regards to (a) the recruitment of both in- and outpatients, (b) individual tailoring and delivery, (c) the CRT materials adapted to suit young females with AN, and (d) the acceptability for clinicians involved in the study. There were no voluntary dropouts, with 19 of 20 patients completing the entire course of treatment. CONCLUSIONS The findings have implications for the refinement of CRT for the youngest AN population, and strengthens our understanding of the core components in the development and evaluation of novel interventions targeting AN. This study will help inform the design of a subsequent randomized controlled trial.

Abstract
OBJECTIVE Anorexia nervosa (AN) is a severe illness with high rates of relapse. Exposure and Response Prevention for AN (AN-EXRP) is a new approach that specifically addresses maladaptive eating behavior by targeting eating-related fear and anxiety. The aim of this study was to evaluate AN-EXRP as an adjunctive strategy to improve eating behavior during weight restoration, at a pivotal moment when treatment goals shift toward relapse prevention. METHOD A randomized controlled trial was conducted to compare AN-EXRP with a comparison condition, Cognitive Remediation Therapy (CRT). Hospitalized patients with AN (n = 32) who had achieved weight restoration to a BMI > 18.5 kg/m(2) received 12 sessions of either AN-EXRP or CRT. Outcome was assessed by change in caloric intake in an objective assessment of eating behavior. RESULTS The average test meal caloric intake of participants who received AN-EXRP increased from 352 ± 263 kcal at baseline to 401 ± 215 kcal post-treatment, while that of participants who received CRT decreased from 501 ± 232 kcal at baseline to 424 ± 221 kcal post-treatment [t(28) = 2.5, p = .02]. Improvement in intake was significantly associated with improvement in eating-related anxiety (Spearman's ρ = 0.40, p = .03). DISCUSSION These data demonstrate that AN-EXRP, compared to a credible comparison intervention, is associated with better caloric intake in a laboratory meal over time in AN. Additional studies are required to determine whether incorporation of these techniques into a longer treatment program leads to enduring and clinically significant change.

Abstract
OBJECTIVE Adults with anorexia nervosa (AN) show weaknesses in several cognitive functions before and after weight restoration. There is a great demand for standardized examinations of executive functioning in the field of child and adolescent AN. Previous studies exhibited methodological inconsistencies regarding test selection and operationalization of cognitive functions, making the interpretation of their findings difficult. In order to overcome these inconsistencies, a neuropsychological assessment tool, the "Ravello Profile," was developed, though previously not available in German. This paper presents a German adaptation of the Ravello Profile and illustrates its applicability in children and adolescents via three case descriptions. METHODS The Ravello Profile was adapted for the German-speaking area. The applicability of the Ravello Profile was evaluated in three children and adolescents with AN. RESULTS AND CONCLUSIONS The cases presented confirm the feasible implementation of this adaptation of the Ravello Profile, both in children and adolescents. Hence, it enables a methodologically consistent examination of executive functioning in German-speaking children, adolescents, and adults with AN. Using the Ravello Profile, the role of cognitive functions in the development of AN can be systematically examined over a broad age range.

Abstract
OBJECTIVE To systematically review studies of cognitive remediation therapy (CRT) for anorexia nervosa (AN), and to discuss findings with references to clinical practice and future research. METHOD The literature was reviewed using the PubMed, Web of Science and PsycINFO search terms "cognitive remediation therapy" AND "anorexia nervosa". Papers published online between 2005 and 2013 were selected on the basis of three inclusion criteria: 1) studies of any design focusing on CRT for AN, 2) papers that were written in English or had an available published English translation, and 3) papers published in peer reviewed journals. RESULTS A total of 45 papers were identified of which 21 were recognized as being relevant for the review. Relevant papers were divided into three different categories 1) single case reports, 2) case series and 3) randomised controlled trials (RCTs). Single case studies and case series yielded strong evidence of feasibility and acceptability of CRT for AN despite great variety in sample compositions. Four RCTs demonstrate that CRT has the potential of enhancing the effectiveness of current treatments, reduce attrition, increase cognitive set-shifting abilities and quality of life, as well as reduce eating disorder psychopathology. DISCUSSION The number of CRT studies published is growing rapidly, in particular RCTs. Further research is needed to define the primary aim of delivering CRT to patients with eating disorders, and to establish how to best measure the effect of the intervention. Moreover, researchers and clinicians should focus on identifying and assessing specific versus non-specific CRT contributions, and explore long-term effects of the intervention. It is imperative that adolescent RCTs are conducted to evaluate how CRT may be effective as a treatment for this young patient group.

Abstract
OBJECTIVE Inefficient cognitive flexibility is considered a neurocognitive trait marker involved in the development and maintenance of anorexia nervosa (AN). Cognitive Remediation Therapy (CRT) is a specific treatment targeting this cognitive style. The aim of this study was to investigate the feasibility and efficacy (by estimating the effect size) of specifically tailored CRT for AN, compared to non-specific cognitive training. METHOD A prospective, randomized controlled, superiority pilot trial was conducted. Forty women with AN receiving treatment as usual (TAU) were randomized to receive either CRT or non-specific neurocognitive therapy (NNT) as an add-on. Both conditions comprised 30 sessions of computer-assisted (21 sessions) and face-to-face (9 sessions) training over a 3-week period. CRT focused specifically on cognitive flexibility. NNT was comprised of tasks designed to improve attention and memory. The primary outcome was performance on a neuropsychological post-treatment assessment of cognitive set-shifting. RESULTS Data available from 25 treatment completers were analyzed. Participants in the CRT condition outperformed participants in the NNT condition in cognitive set-shifting at the end of the treatment (p = 0.027; between-groups effect size d = 0.62). Participants in both conditions showed high treatment acceptance. DISCUSSION This study confirms the feasibility of CRT for AN, and provides a first estimate of the effect size that can be achieved using CRT for AN. Furthermore, the present findings corroborate that neurocognitive training for AN should be tailored to the specific cognitive inefficiencies of this patient group.

Abstract
AIM To explore the relationship between visuospatial memory, weak central coherence, and eating disorder (ED) symptoms in anorexia nervosa (AN) inpatients. SAMPLE 31 female AN inpatients. METHODS Rey complex figure test (RCFT) was used to assess both visuospatial memory and central coherence. RCFT consisted of copy and recall trials. ED symptoms were assessed by The Eating Disorder Examination-Questionnaire (EDE-Q) and The Clinical and Research Inventory for Eating Disorders (CR-EAT). RESULTS We found a statistically significant negative correlation between recall accuracy and the total EDE-Q score. Furthermore, recall accuracy and recall central coherence significantly negatively correlate with several EDE-Q and CR-EAT scales. CONCLUSIONS These findings may contribute to a better understanding of cognitive impairments specifically in ED, and to refining interventions aiming at their improvement.

Abstract
OBJECTIVE There is considerable literature regarding the effectiveness of cognitive remediation (CR) in schizophrenia and in conditions such as stroke and traumatic brain injury. Patients with major depressive disorder (MDD) present with significant cognitive impairment which in many cases may not resolve with treatment. Neurobiological data suggest that this may relate to underlying dysfunction of pre-frontal cortical areas of the brain and their connections with limbic structures. There has been limited research into specific CR to activate these areas and target impaired cognitive function in MDD. We therefore review current evidence, examine the theoretical basis for and present a rationale for research into CR in MDD. In addition, we will examine important methodological issues in developing such an approach. METHOD Based on preliminary studies using CR-based techniques, data from CR in schizophrenia, data regarding baseline and residual cognitive impairment in depression, and knowledge of the neurobiology of MDD, we examine the possible utility of CR strategies in the treatment of MDD and make recommendations for research in this area. RESULTS A small number of previous studies have examined specific CR in MDD. The studies are small and inconclusive. However, data on the neuropsychological function and neurobiology of MDD suggest that this is an approach that deserves further attention and research. CONCLUSIONS Further research is required in carefully selected populations, using well-defined CR techniques and some form of comparator treatment.

Abstract
Few treatments for eating disorders have established a base of empirical support, and those that have are still limited by high dropout rates and low abstinence rates. Thus, there is a critical need for innovative eating disorder treatments to fill this gap. The past decade has seen a surge in the development of novel treatments that address eating pathology. This review provides an overview of the emerging psychological treatments for eating disorders, including descriptions of the therapeutic rationales, treatment techniques, and research support. The review will cover face-to-face interventions that are provided in the context of individual or group psychotherapy. Treatments included in this review were organized into the following six categories based on their underlying therapeutic rationales: (1) cognition-focused approaches, (2) emotion regulation approaches, (3) exposure-based approaches, (4) motivational enhancement, (5) integrative approaches, and (6) family- and couple-based interventions.

Abstract
The vast majority of studies in anorexia nervosa that have investigated the domains of central coherence, organizational strategy, and visuospatial memory have focused on adult samples. In addition, studies investigating visuospatial memory have focused on free recall. No study to date has reported the association between recognition memory and central coherence or organizational strategy in younger people with this disorder, yet the capacity to recognize previously seen visual stimuli may contribute to overall visuospatial ability. Therefore, we investigate these domains in children and adolescents with anorexia nervosa compared to age- and gender-matched healthy controls. There were no significant group differences in immediate, delayed, or recognition memory, central coherence, or organization strategy. When compared with controls, patients with anorexia nervosa scored significantly higher on accuracy and took significantly longer when copying the Rey Complex Figure Task. Caution must be taken when interpreting these findings due to lower-than-expected scores in memory performance in the control group and because of a potential lack of sensitivity in the measures used when assessing this younger population. For neuropsychological functions where no normative data exist, we need a deeper, more thorough knowledge of the developmental trajectory and its assessment in young people in the general population before drawing conclusions in anorexia nervosa.

Abstract
BACKGROUND A number of characteristics associated with Autism Spectrum Disorders (ASD) are over-represented among patients with Anorexia Nervosa (AN) as well as among relatives of these patients. Yet the co-occurrence of autistic traits in AN has not been fully explored and no previous study has directly compared self-reported evaluations of cognitive and socio-affective skills in AN and ASD. METHODS We aimed to determine the degree of overlap between AN and ASD from scores on questionnaires classically used to measure ASD impairments. Fifteen AN participants, 15 ASD participants and two groups of matched controls completed a battery of self-reports measuring: autistic traits (Autism-Spectrum Quotient), empathy (Empathy Quotient-short and Interpersonal Reactivity Index), systemizing (Systemizing Quotient-short) and alexithymia (Bermond-Vorst Alexithymia Questionnaire-B). Univariate comparisons of mean totalled scores were performed on each measure (patients vs. controls, and AN vs. ASD), and a Principal Component Analysis was used to study subject proximities in a reduced-factor space constructed from AQ, BVAQ-B and IRI subscales. RESULTS These analyses revealed similarities in a few cognitive domains (Attention Switching, Perspective Taking and Fantasy, lack of emotional introspection) and in some nonspecific affective dimensions (depression and feelings of distress), but also marked dissimilarities in social skills (the ability to communicate emotions to others, empathizing). CONCLUSION The AN and ASD participants reported similar needs for sameness, and similar difficulties understanding their emotions and taking the perspective of another, but contrasting abilities to feel concerned in interpersonal situations. Our mixed findings encourage further exploration of transdiagnostic similarities and associations between these disorders.

Abstract
OBJECTIVE To investigate neuropsychological functioning in adolescents with anorexia nervosa (AN) before and after receiving cognitive remediation therapy (CRT). METHOD Twenty young females with AN participated in an individually-delivered CRT treatment program. Neuropsychological and psychiatric assessments were administered before and after treatment. Weight, depression, anxiety, duration of illness, and level of eating disorder psychopathology were considered as covariates in statistical analyses. RESULTS Significant changes in weight, depression, visio-spatial memory, perceptual disembedding abilities, and verbal fluency were observed. Changes in weight had a significant effect on improvements in visuo-spatial memory and verbal fluency. Results also revealed a significant effect of depressive symptoms on perceptual disembedding abilities. DISCUSSION The results suggest improvements on a number of neuropsychological functions during the course of CRT. Future studies should explore the use of additional assessment instruments, and include control groups to assess the effectiveness of the intervention.

Abstract
OBJECTIVE There are limited data supporting specific treatments for adults with anorexia nervosa (AN). Randomized clinical trials (RCTs) for adults with AN are characterized by high attrition limiting the feasibility of conducting and interpreting existing studies. High dropout rates may be related to the inflexible and obsessional cognitive style of patients with AN. This study evaluated the feasibility of using cognitive remediation therapy (CRT) to reduce attrition in RCTs for AN. METHOD Forty-six participants (mean age of 22.7 years and mean duration of AN of 6.4 years) were randomized to receive eight sessions of either CRT or cognitive behavioral therapy (CBT) over 2 months followed by 16 sessions of CBT for 4 months. RESULTS During the 2-month CRT vs. CBT treatment, rates of attrition were lower in CRT (13%) compared with that of CBT (33%). There were greater improvements in cognitive inefficiencies in the CRT compared with that of the CBT group at the end of 2 months. There were no differences in other outcomes. DISCUSSION These results suggest that CRT is acceptable and feasible for use in RCTs for outpatient treatment of AN. CRT may reduce attrition in the short term. Adequately powered future studies are needed to examine CRT as an outpatient treatment for AN.

Abstract
AIM In this study, we aim to explore the feasibility and acceptability of group cognitive remediation therapy (CRT) for anorexia nervosa (AN) inpatients, and to suggest modifications for future use. METHODS We performed ten 45-min CRT sessions, once a week, in two consecutive groups of adult AN inpatients. The groups consisted of 14 and 20 participants, respectively. At the end of each session, participants filled in a questionnaire asking them to evaluate whether and how they benefited from the exercise RESULTS Group-based CRT could be well incorporated into the therapeutic program of the Eating Disorders Unit, and was well received by the participants. Based on patients' feedback and our observations, we discuss several options for future modifications.

Abstract
OBJECTIVES To investigate whether attention to detail is a similarly strong candidate endophenotype of anorexia (AN) and bulimia nervosa (BN), and to explore the incidence and clinical correlates of attention to detail. METHODS A total of 266 women (including AN, BN, recovered AN, unaffected sisters of AN/BN & control women) undertook a thorough clinical assessment and were administered two neuropsychological measures of attention to detail (Group Embedded Figure Test; Rey-Osterrieth Complex Figure). RESULTS Superior attention to detail was found across all AN groups including recovered AN and unaffected AN sisters. Those with BN and their unaffected sisters showed a profile more consistent with poor global integration. The combined effect of superior attention to detail and poor global integration ("weak coherence") was present in 42.3% of active cases and corresponded with a more severe illness, elevated obsessive-compulsive symptoms, and a higher likelihood of comorbid clinical anxiety and self-harm. CONCLUSIONS Attention to detail is a stronger candidate endophenotype of AN compared to BN, where poor global integration may be more relevant. The unique contribution of both aspects of weak coherence (superior attention to detail/poor global integration) requires further exploration and understanding in both eating disorders. Integrating cognitive remediation of these traits into treatment for the subset of patients it is relevant for may improve outcome.

Abstract
BACKGROUND Patients with anorexia may have elevated autistic traits. In this study, we tested test whether patients with anorexia nervosa (anorexia) have an elevated score on a dimensional measure of autistic traits, the Autism Spectrum Quotient (AQ), as well as on trait measures relevant to the autism spectrum: the Empathy Quotient (EQ), and the Systemizing Quotient (SQ). METHODS Two groups were tested: (1) female adolescents with anorexia: n = 66, aged 12 to 18 years; and (2) female adolescents without anorexia: n =1,609, aged 12 to 18 years. Both groups were tested using the AQ, EQ, and SQ, via the parent-report adolescent versions for patients aged 12 to 15 years old, and the self-report adult versions for patients aged over 16 years. RESULTS As predicted, the patients with anorexia had a higher AQ and SQ. Their EQ score was reduced, but only for the parent-report version in the younger age group. Using EQ-SQ scores to calculate 'cognitive types', patients with anorexia were more likely to show the Type S profile (systemizing (S) better than empathy (E)), compared with typical females. CONCLUSIONS Females with anorexia have elevated autistic traits. Clinicians should consider if a focus on autistic traits might be helpful in the assessment and treatment of anorexia. Future research needs to establish if these results reflect traits or states associated with anorexia.

Abstract
BACKGROUND Anorexia nervosa is characterized by high levels of perseveration and inflexibility, which interfere with successful treatments. Dopamine (DA) signalling seems to play a key role in modulating the prefrontal cortex, since both DA deficiency and excess nega tively influence the efficiency of cognitive functions. The present study explores the effect of a functional polymorphism (Val158Met) in the catechol-O-methyltransferase (COMT) gene on the set-shifting abilities and prefrontal functional connectivity of patients with anorexia nervosa. METHODS All participants performed the Wisconsin Card Sorting Task, and a subsample underwent resting-state functional magnetic resonance imaging. RESULTS We included 166 patients with DSM-IV lifetime anorexia nervosa and 140 healthy women in our study. Both underweight and weight-recovered patients with anorexia nervosa showed high levels of perseveration, but only in the underweight group did the Val158Met polymorphism affect cognitive performance, showing the U-shaped curve characteristic of increased DA signalling in the prefrontal cortex. Underweight patients with anorexia nervosa who are Met homozygotes had significantly higher levels of perseveration and increased prefrontal functional connectivity than underweight patients in the other genotype groups, indicating abnormal regional cortical processing. LIMITATIONS Although our data show that grey matter reduction in starving patients with anorexia nervosa did not explain our findings, the cross-sectional design of the present study did not allow us to distinguish between the effects of starvation and those of low estrogen levels. CONCLUSION Starvation affects DA release in the prefrontal cortex of patients with anorexia nervosa with different effects on executive functioning and prefrontal functional connectivity according to the COMT genotype. This observation has several therapeutic implications that need to be addressed by future studies.
