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.

Adolescents With Autism Spectrum Disorder and Anorexia Nervosa Comorbidity: Common Features and Treatment Possibilities With Cognitive Remediation Therapy and Oxytocin.

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
INTRODUCTION AND PURPOSE Current literature shows promising results regarding the efficacy of Cognitive Remediation Therapy for Anorexia Nervosa (AN); however, there is a paucity of studies considering the use of CRT in Young People (YP). The aim of this study was to examine YP's experiences of individual CRT in an inpatient eating disorder unit. METHOD Seventy letters following a cycle of eight individual CRT sessions were analysed using thematic analysis, adopting an inductive approach. Inter-rater reliability of findings was ensured. RESULTS The following six higher-order themes, each with lower-order themes, were identified: engaging aspects of CRT; identifying thinking skills; relevance to real-life situations; encountering personal challenges; making sense of the rational of CRT; suggestions for further improvements. YP reported enjoying CRT and described increased learning about their thinking styles and their skills from the activities undertaken during therapy. Some participants were able to apply learning outside of therapy and less frequently to difficulties related to the illness. CONCLUSION Feedback from patients suggests CRT is a useful intervention for YP with AN, which could facilitate their engagement in the treatment, while tackling neuropsychological processes underlying psychological symptoms of AN. Exploring participants' experience of CRT has highlighted specific elements of the intervention perceived as beneficial by YP, and areas where adaption could be made. This will allow clinicians to further develop the intervention from a service users' perspective, tailoring the sessions to their needs.

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
Cognitive remediation therapy (CRT) is an intervention for anorexia nervosa (AN) that focuses on ameliorating the neuropsychological inefficiencies that underlie the illness. The current literature has reported promising results regarding its efficacy as an intervention for AN. However, there is a scarcity of studies considering the implementation of CRT in a child and adolescent population. This article describes an individual CRT therapy programme for children and adolescents with AN delivered on an inpatient unit for eating disorders. It considers the therapeutic process including the differing viewpoints of the patients and the therapists. The article concludes that CRT can be viewed as an engaging therapeutic intervention that could be useful as an additional treatment for AN.

Abstract
There is increasing interest in group therapy for the treatment of eating disorders. However, there is a lack of research evaluating group therapy that reflects on patient feedback in order to inform practice and improve treatment. This exploratory qualitative study attempted to evaluate patient feedback about the group therapy offered on a specialist inpatient eating disorders program. This qualitative analysis of patients' feedback highlights areas for improvement that can be targeted to increase the effectiveness of the psychotherapy groups in the future. The research has implications for making inpatient hospitalization more effectively tailored to patients' needs. This study also helps to improve qualitative research protocols.

Abstract
OBJECTIVE This review aims to examine the impact of depressive symptoms on the assessment of cognitive flexibility, central coherence, and decision-making in individuals with anorexia nervosa (AN). METHOD An online search was carried out using PubMed and PsycInfo. Articles were selected for review if they were published in English between 1990 and 2014 and used the Wisconsin Card Sorting Test, the Trail Making Task parts A and B, the Brixton Test, the Rey-Osterrieth Complex Figure Test, and/or the Iowa Gambling Task. RESULTS Sixty-two studies were included. Thirty (48%) of the studies statistically assessed the association between depression and neurocognition in AN versus healthy controls. Where significant correlations were found, it became clear that the more serious the depression, the greater the neuropsychological impairment. Only six (10%) studies examined whether increased depressive symptoms were able to eliminate the differences between individuals with AN and healthy controls, and one study found that depressive symptoms did eliminate group differences in cognitive flexibility and decision-making. DISCUSSION Only a subgroup of articles on neuropsychology in AN adjusted for depression. However, given the role of depression that some articles suggest, future studies should pay closer attention to the evaluation of this potential confounder.

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
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
OBJECTIVE Cognitive remediation therapy (CRT) seems to be increasingly interesting in the treatment of anorexia nervosa for adult patients. We attempted to apply this support to a group of young inpatients, initially to assess its feasibility and acceptability, and then to improve its content for therapeutic application and future research. METHODS Ten 12- to 17-year-old inpatients with primary DSM-IV diagnosis of anorexia nervosa participated in a 10-week intervention program with a one-hour group session of CRT per week. All 10 patients were assessed before the intervention and those who completed the 10 sessions were assessed after. Assessment included a clinical examination by a psychiatrist, a battery of clinical inventories, and set-shifting tests. Moreover, each patient wrote a letter providing feedback on the intervention for subsequent analysis. RESULTS Only two patients completed all 10 sessions, the other eight who were discharged from the hospital in the meantime could not attend the sessions for practical reasons. After the 10 sessions, an improvement in BMI and in measured levels of some psychopathological symptoms was observed in our two patients. Most neuropsychological task performances were improved after cognitive remediation. Feedback from the 10 patients was generally positive. CONCLUSION AND IMPLICATIONS FOR PRACTICE This preliminary investigation suggests that cognitive remediation therapy is acceptable and feasible in this population. Replication of these findings requires a larger sample, improvement of the trial design, more sensitive measures, and another training format to avoid loss of so many participants.

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
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.

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
In order to explore if neuropsychological deficits on visual constructional ability could be related to risk eating behaviors, a total of 102 women were evaluated, 51 of the participants had been formally diagnosed with eating disorders and 51 did not. All participants were given the Eating Attitude Test (EAT-40), The Rey-Osterrieth Complex Figure and The Tower of London Task. Results revealed the existence of a deficit on visual integration similar to those observed in other studies with diagnosed patients. The group at risk showed a comparatively reduced ability on the tasks and the control participants' execution was on the average. Findings revealed the need for designing studies to evaluate neuropsychological processes as possible risk factors which predict eating disorders.

Abstract
OBJECTIVE Recent research has identified specific cognitive deficits in patients with anorexia nervosa (AN), including impairment in executive functioning and attention. Another such cognitive process, implicit category learning has been less studied in AN. This study examined whether implicit category learning is impaired in AN. METHOD Twenty-one women diagnosed with AN and 19 control women (CW) were administered an implicit category learning task in which they were asked to categorize simple perceptual stimuli (Gabor patches) into one of two categories. Category membership was based on a linear integration (i.e., an implicit task) of two stimulus dimensions (orientation and spatial frequency of the stimulus). RESULTS AN individuals were less accurate on implicit category learning relative to age-matched CW. Model-based analyses indicated that, even when AN individuals used the appropriate (i.e., implicit) strategy they were still impaired relative to CW who also used the same strategy. In addition, task performance in AN patients was worse the higher they were in self-reported novelty seeking and the lower they were in sensitivity to punishment. CONCLUSIONS These results indicate that AN patients have implicit category learning deficits, and given this type of learning is thought to be mediated by striatal dopamine pathways, AN patients may have deficits in these neural systems. The finding of significant correlations with novelty seeking and sensitivity to punishment suggests that feedback sensitivity is related to implicit learning in AN.

Cognitive flexibility in verbal and nonverbal domains and decision making in anorexia nervosa patients: a pilot study. BMC Psychiatry 2011; 11:162.

Abstract
BACKGROUND This paper aimed to investigate cognitive rigidity and decision making impairments in patients diagnosed with Anorexia Nervosa Restrictive type (AN-R), assessing also verbal components. METHODS Thirty patients with AN-R were compared with thirty age-matched healthy controls (HC). All participants completed a comprehensive neuropsychological battery comprised of the Trail Making Test, Wisconsin Card Sorting Test, Hayling Sentence Completion Task, and the Iowa Gambling Task. The Beck Depression Inventory was administered to evaluate depressive symptomatology. The influence of both illness duration and neuropsychological variables was considered. Body Mass Index (BMI), years of education, and depression severity were considered as covariates in statistical analyses. RESULTS The AN-R group showed poorer performance on all neuropsychological tests. There was a positive correlation between illness duration and the Hayling Sentence Completion Task Net score, and number of completion answers in part B. There was a partial effect of years of education and BMI on neuropsychological test performance. Response inhibition processes and verbal fluency impairment were not associated with BMI and years of education, but were associated with depression severity. CONCLUSIONS These data provide evidence that patients with AN-R have cognitive rigidity in both verbal and non-verbal domains. The role of the impairment on verbal domains should be considered in treatment. Further research is warranted to better understand the relationship between illness state and cognitive rigidity and impaired decision-making.

Abstract
A number of specific deficits in neuropsychological functioning in anorexia nervosa (AN) have been identified. However, it is not known whether these specific deficits cluster together to form one or more clear neuropsychological profiles. We present a case series of nine participants who were recruited as part of a wider, ongoing investigation of the neuropsychological profile of eating disorders (the Ravello Profile). Results show that there was a wide range of different neuropsychological profiles at initial assessment. This suggests a spectrum of neuropsychological strengths and weaknesses that would otherwise be masked in a cohort analysis. It is anticipated that factor and cluster analytic studies will establish one or more common profiles of neuropsychological deficits in AN.

Abstract
Cognitive Remediation Therapy (CRT) was designed to address the inflexible and detail focused thinking styles frequently reported in individuals with Anorexia Nervosa (AN). This paper reports the development and acceptability of a pilot of CRT for AN in group format. Four group sessions were designed and piloted with 30 patients in an eating disorder service. The voluntary drop out rate was 20%. Outcome measures targeting patients' self-reported cognitive flexibility, self esteem and motivation to change were completed in the first and last sessions. Statistically significant gains were found in self reported ability to change (p=0.03). Both patients and group facilitators found the group acceptable, useful and a positive experience.

Abstract
The present study investigated cognitive disinhibition in bulimia nervosa (BN) and examined whether impulsivity could account for this neuropsychological deficiency. Inhibitory processing of 13 women with BN (16-29 years) was compared against that of 13 healthy control participants matched for age, education, and socioeconomic status on a battery of widely used tasks: Stroop task, Haylings sentence completion test, excluded letter fluency, and Matching Familiar Figures Test. The women were also administered the Barratt Impulsiveness Scale (BIS-11). The BN patients displayed significant impairments on all inhibition measures and posited significantly higher impulsivity scores than the controls. Moreover, controlling for impulsivity reduced the group differences in Stroop color naming and excluded letter fluency to nonsignificance, indicating that poor inhibitory control in BN is at least partly attributable to an impulsive disposition.

Abstract
In this chapter, we aim to address some basic conceptual and practical questions about cognitive remediation therapy (CRT) for eating disorders. We begin by providing an overall historical, conceptual, and theoretical framework for CRT. Next, we discuss the specific indications for how and why CRT might be useful for eating disorders based on existing neuropsychological research evidence. We also provide an overview of the types of tasks and stimuli used in CRT and a general protocol for a manualized version of CRT. In addition, modifications of the adult CRT manual for use with adolescents as well as preliminary acceptability of the approach with this younger age group are described. We also propose various ways to integrate CRT in a variety of inpatient and outpatient programmes. Finally, a discussion of potential future directions in research using the tools of neurocognitive assessment, imaging and treatment research is provided.

Abstract
OBJECTIVE There is little evidence to guide the treatment of anorexia nervosa (AN). Cognitive Remediation Therapy (CRT) may be helpful in reducing perfectionism and rigidity and preparing patients for involvement in later psychological interventions. The aim of this study was to examine service users' experiences of participating in CRT. METHOD Written feedback, following 10 CRT sessions, from 19 AN patients was analyzed using grounded theory approach. RESULTS Patients' feedback was generally positive. They found CRT refreshing and appreciated that it did not revolve around food. Patients found CRT helpful in reducing perfectionism and rigidity. The majority expressed how they were able to implement skills in their real life. Some changes were suggested, these included varying levels of difficulty and more guidance in implementing skills. CONCLUSION CRT is a promising component in the treatment of AN. Further research is being conducted to evaluate CRT.

Abstract
OBJECTIVE To examine the concept of central coherence in women with bulimia nervosa (BN) and address similarities and difference with those with anorexia nervosa (AN) METHOD: Forty two women with BN and 42 matched healthy women, completed neuropsychological testing measuring aspects of central coherence: Rey-Osterrieth Complex Figure (RCFT), Embedded Figures Test (EFT), Block Design Test (BD), Homograph Reading Test (HRT), and Sentence Completion Task (SCT). RESULTS The BN group showed superiority in local processing as measured by EFT and lesser relative advantage from segmentation in BD, and difficulties in global processing in both visual and verbal domains as examined by RCFT, HRT, and SCT. Anxiety levels were associated with low central coherence indices in RCFT. CONCLUSION People with BN displayed a profile consistent with the weak central coherence hypothesis. Their pattern of cognitive performance resembles that seen in AN although some differences are apparent.

Abstract
OBJECTIVE To examine central coherence (local and global processing) in women with anorexia nervosa (AN). METHOD 42 women with AN and 42 healthy women (HC) completed neuropsychological testing measuring visuospatial and verbal aspects of central coherence: Rey-Osterrieth Complex Figure (RCFT), Embedded Figures Test (EFT), Homograph Reading Test (HRT), and Sentence Completion Task (SCT). RESULTS People with AN displayed superior performance on the EFT and poorer performance in RCFT with the exception of accuracy in the copy trial. Long hesitations in the SCT were observed. Verbal coherence tasks were not sensitive enough to detect coherence anomalies in AN. CONCLUSION Women with AN have strengths in tasks requiring local processing (EFT) and weaknesses on tasks benefited by global processing (RCFT and SCT). These results are consistent with the weak central coherence account. This trait might play a role in the maintenance of AN and can be addressed in specific clinical interventions.

Abstract
It is hoped that the greater understanding neuroscience will bring to the field of psychiatry will lead to a more biologically based system of classification and diagnosis for psychiatric disorders. The clarification of endophenotypes might produce the ‘macros’ from which such a system could be constructed. The aim of this paper is to discuss the evidence for continuities between eating disorders and developmental disorders of childhood (autistic spectrum disorders and attention-deficit hyperactivity disorder) and possible shared endophenotypes. We review the evidence for obsessive–compulsive traits and disinhibition as intermediate phenotypes, and for information-processing styles such as weak set shifting, central coherence, disinhibition and reward sensitivity as possible endophenotypes. Finally we discuss the implications that this has for treatment.
