[Anorexia nervosa in the light of neurocognitive functioning: New theoretical and therapeutic perspectives]

Validation study of the apathy motivation index in French adults

Objective

Apathy is present in many brain disorders, but it is also prevalent to varying degrees in healthy people. While many tools have been developed to assess levels of apathy in pathology, no standardized measure of apathy in healthy people exists.

Method

Therefore, this study aimed to validate the French version of the Apathy Motivation Index (f-AMI). The results of 729 participants were analyzed using an exploratory factorial analysis.

Results

Preliminary analyses suggested that the three domains of apathy extracted in the original AMI scale-behavioral activation (BA), social motivation (SM), and emotional sensitivity (ES)-could be found also in the f-AMI. A further exploratory analysis showed that a higher number of factors could be extracted, particularly for women. Specifically, both social and emotional factors could be divided into two sub-factors: (1) social motivation toward strangers or toward an acquaintance and (2) self-directed emotional sensitivity directed toward others. Regarding construct validity, the scores of f-AMI were correlated with the French Dimensional Apathy Scale results. Concerning the divergent validity, emotional sensitivity in apathy is different from depression, anhedonia, and fatigue levels.

Conclusion

These results suggest that the f-AMI can be used to assess levels of apathy in healthy adults.

Perspectives of underweight people with eating disorders on receiving Imagery Rescripting trauma treatment: a qualitative study of their experiences

BACKGROUND

The prognosis for underweight individuals with an eating disorder (ED) and posttraumatic stress disorder (PTSD) is worse than for their peers without these comorbid symptoms. This qualitative study explores the experiences of trauma-focused Imagery Rescripting (ImRs) therapy of underweight inpatients being treated for an ED.

OBJECTIVE

To test the feasibility and to improve ImRs by understanding the experiences and perspectives of people with an ED and PTSD who, when underweight, received ImRs as an adjunct to their inpatient ED treatment.

METHOD

To explore how underweight people with an ED experience and perceive ImRs, we used a qualitative study design involving semi-structured interviews with 12 participants. After analysis, the data were summarized and classified within a thematic framework that focused on experiences and improving the ImRs method.

RESULTS

The thematic analysis resulted in the following 6 main themes; (1) Expectations of ImRs; (2) Ability to participate in ImRs; (3) Effect of ImRs; (4) Experience of ImRs technique; (5) Conditions under which ImRs is given; (6) In depth-analysis. The results show that despite the fear of disappointment the participants appreciate addressing the PTSD and ED symptoms simultaneously. Further, results showed that it had been possible for them to attend ImRs but that the effects of ImRs were not uniformly perceived. Also, participants indicated that a caring context is important and that ImRs should not be scheduled immediately before a meal. Finally, the treatment generated hope.

CONCLUSIONS

The findings of this study demonstrated the feasibility of the integration of ImRs trauma treatment for individuals who are being treated in an ED inpatient treatment setting, and are in contrast to standard practice where the focus of inpatient treatment has been ED-symptom improvement without comprehensively addressing past traumatic experiences during an underweight phase.

Treating PTSD with Imagery Rescripting in underweight eating disorder patients: a multiple baseline case series study

BACKGROUND

Eating disorder patients with posttraumatic stress disorder have worse treatment results regarding their eating disorder than patients without posttraumatic stress disorder. Many eating disorder patients with co-morbid posttraumatic stress disorder symptoms are not treated for posttraumatic stress disorder symptoms during an underweight state. We propose that treatment of posttraumatic stress disorder is possible for underweight patients and that their trauma symptoms decrease with the use of Imagery Rescripting. We also investigated whether treatment of trauma influences eating disorder pathology in general and the process of weight gain specifically.

METHOD

Ten patients in clinical treatment (BMI 14-16.5) participated. A multiple baseline design was used, with baseline varying from 6 to 10 weeks, a 6-week treatment phase, a 3-week follow-up period and a 3-month follow-up measurement. Data were analysed with mixed regression.

RESULTS

Evidence was found that Imagery Rescripting had strong positive effects on posttraumatic stress disorder symptoms without interfering with eating disorder treatment. Positive effects were also found on a range of secondary emotional and cognitive measures.

CONCLUSION

Imagery Rescripting of traumatic memories is a possible and safe intervention for underweight eating disorder patients. It also had positive clinical effects.

Pathways to orthorexia nervosa: a case series discussion

BACKGROUND

Orthorexia nervosa (ON) has gained increasing interest in the last 2 decades. Although a consensus on the diagnostic boundaries of ON has not yet been reached, there is some evidence for an overlap with eating disorders, obsessive-compulsive disorder, and psychotic disorder. Most of the knowledge about ON has emerged from studies of non-clinical and at-risk populations and is focused on differential diagnosis; therefore, further clinical studies are needed to better outline the ON phenomenon in a real-life setting.

OBJECTIVE

This case series aims at describing clinical cases that developed symptoms suggestive of ON after being diagnosed with a prior psychiatric disorder and then discussing them in light of possible clinical pathways.

METHODS

Four women consecutively admitted to an outpatient unit for the treatment of eating disorders were diagnosed with ON through a clinical interview, according to Dunn and Bratman's criteria and self-administered questionnaire assessment (ORTO-15), and were considered to be eligible for this case series study. Psychiatric anamnestic data were collected retrospectively.

RESULTS

The anamnesis revealed that all patients were previously diagnosed with a psychiatric disorder (i.e. obsessive-compulsive disorder, bulimia nervosa, illness anxiety disorder, and psychotic disorder) before developing ON.

CONCLUSION

Past literature focused on differential diagnosis between ON and other psychiatric disorders. This is the first description of clinical cases in a real-life setting that started with different psychiatric disorders and later developed symptoms suggestive of ON. These cases have generated a new research question on the possibility that different psychiatric disorders may associate with a later onset of ON.

LEVEL OF EVIDENCE

Level V, descriptive study.

Cognitive Function in Adults with Enduring Anorexia Nervosa

Anorexia Nervosa (AN) is a severe and often enduring disorder characterized by restriction of food intake, low body weight, fear of weight gain, and distorted body image. Investigations on cognition performance in AN patients have yielded conflicting results. Using an established and sensitive computerized cognitive test battery, we aimed to assess core aspects of cognitive function, including attention span, information processing, reasoning, working and episodic memory, in AN patients and controls. Patients were recruited from the Danish Prospective Longitudinal all-comer inclusion study in Eating Disorders (PROLED). Included were 26 individuals with AN and 36 healthy volunteers (HV). All were tested with CogTrack (an online cognitive assessment system) at baseline, and AN patients were tested again at a follow-up time point after weight increase (n = 13). At baseline, AN patients showed faster reaction times in the attention tasks, as well as increased accuracy in grammatical reasoning compared to HV. There were no differences in cognitive function between AN patients and HV in the other cognitive domains measured (sustained attention, working and episodic memory, speed of retrieval, and speed of grammatical reasoning). No differences were visible in the AN sample between baseline and follow-up. Performance did not correlate with any clinical variables in the AN sample. These findings supplement results from other studies suggesting increased concentration and reasoning accuracy in patients suffering from AN, who showed increased performance in cognitive tasks despite their illness.

Self-defining memories in female patients with anorexia nervosa

OBJECTIVE

Overgeneral autobiographical memory (AM) was reported in patients with anorexia nervosa (AN) using AM cueing tasks that did not directly indexes memories that are personally important to the individual, that is, self-defining memories (SDMs). The aim of this study is to investigate characteristics of SDMs in females with AN.

METHOD

A total of 46 outpatients with chronic AN and 52 healthy controls (HC) were asked to recall three SDMs.

RESULTS

Compared to HC, patients with AN presented less specific SDMs, but have preserved ability to give meaning to their memories. Patients' SDMs were associated with more negative emotions, more tension (i.e. explicit expression of discomfort, disagreement or unease) and more contamination (i.e. transformation in the memory narrative from a positive to a negative affective state). Content of SDMs differed between patients with AN and HC. Finally, no difference was found in SDMs characteristics between the two subtypes of anorexia nervosa (restricting type and binge eating / purging type).

DISCUSSION

Patients with AN recalled overgeneral SDMs with negative content and emotions. In this context, a clinical intervention based on SDMs together with cognitive and emotional remedial therapies could help patients with AN to improve emotion processing and redefine their identity in a more positive way.

Contraception in adolescents with anorexia nervosa. Is there evidence for a negative impact of combined hormonal contraceptives on bone mineral density and the course of the disease?

Objective: Adolescents with anorexia nervosa (AN) are at increased risk of unplanned pregnancies and bone loss, due to low oestrogen levels and low use of efficient contraception. The negative impact of combined hormonal contraceptives (CHC) on peak bone mass during adolescence might limit wider use in anorexic women. Another issue limiting CHC use is the concern, that CHC-induced cyclic bleeding reduces the motivation for further weight gain and thus exerts a negative impact on recovery. We wanted to find evidence based answers about the impact of CHC use on bone health and course of the disease in adolescents with AN.Methods: We performed a narrative review of the current literature investigating the effect of CHC or progestin-only contraceptives on bone density, body shape and course of disease in young women with anorexia.Results: There is no evidence that CHC use aggravates the bone loss associated with AN. In long-term users CHC exert a protective effect. Anorexic women using CHC showed at least the same or a greater weight gain in comparison with controls. Eating disorder attitudes did not worsen.Conclusion: We conclude, that at present there is no evidence, that use of CHC by AN patients has a negative impact on bone density or the course of disease.

Literature Review of Cognitive Neuroscience and Anorexia Nervosa

Studies published between the beginning of 2013 and May 2015 on the neuropsychological functioning of patients with anorexia nervosa compared with healthy participants framed in the context of the Research Domain Criteria matrix identifies evidence for functional differences in three domains: Negative Valance Systems-negative attentional biases and lack of neural responsivity to hunger; Cognitive Systems-limited congruence between clinical and cognitive performance, poorer non-verbal than verbal performance, altered attentional styles to disorder related stimuli, perceptual processing impairment in discriminating body images, weaknesses in central coherence, set shifting weaknesses at low weight status, decision-making weaknesses, and greater neural resources required for working memory; Systems for Social Processes-patients appear to have a different attentional response to faces, and perception and understanding of self and others. Hence, there is evidence to suggest that patients with anorexia nervosa have a specific neuropsychological performance style across tasks in three domains of functioning. Some current controversies and areas for future development are identified.

[Cognitive remediation therapy for children: literature data and clinical application in a child and adolescent psychiatry department]

The hypothesis of cerebral plasticity in psychiatric disorders has encouraged clinicians to develop cognitive remediation therapy (CRT), a new therapeutic approach based on attention, memory, planning, and mental flexibility tasks. The first cognitive remediation programs were developed and validated for adults with schizophrenia and were shown to have a positive impact on executive functions as well as on quality of life. In children and adolescents, researchers emphasized the existence of executive dysfunction in neurodevelopmental disorders such as autistic spectrum disorder, attention deficit disorder, and eating disorders. For these disorders, neuropsychological studies suggest that memory, planning, attention and mental flexibility are impaired. Despite the paucity of studies on cognitive remediation (CR) in children, preliminary results have suggested, as in adults with schizophrenia, good compliance and optimization of executive functioning. Consequently, programs dedicated to young subjects were developed in English-speaking countries, and the Department of Child and Adolescent Psychiatry of Sainte Anne Hospital (Paris) developed a new CR program for children with attention deficit disorder, academic problems, or eating disorders. These programs complete the field of CRT proposed by Sainte Anne Hospital's Remediation and Psychosocial Rehabilitation Reference Center, initially designed for adults with schizophrenia. Our team used and adapted validated tools such as Delahunty and Wykes's CRT program (translated and validated in French by Amado and Franck) and Lindvall and Lask's CRT Resource Pack. One program was developed for an adolescent with anorexia nervosa and applied to the subject and her family, but the purpose of this paper is to present a CR approach for children with attention deficit disorder or academic disorder, a 6-month program based on paper-pencil tasks and board and card games. The team was trained in different kinds of cognitive remediation, and the program was applied by a clinical nurse with the supervision of a child and adolescent psychiatrist and the department's neuropsychologists. Paper-pencil tasks were adapted from the CRT program for adults; the card and board games used were geometric figures, illusions, Rush Hour(®), Set(®), Jungle Speed(®), Color Addict(®), etc. These games are available in stores and the program can be applied at home, which helps families set aside their preoccupations with their child's academic performance. Diagnostic and neuropsychological evaluations were done before the beginning of the therapy and repeated at the end of the 6-month program. This program does not ignore the metapsychological impact of the therapy, and work on self-esteem is also done. The presence of the therapist is necessary, which seems better than a computer program, which cannot encourage the young subject in the same personalized and empathetic way. We therefore conducted the first clinical feasibility trial of cognitive remediation in young subjects and present a clinical case of a 6-year-old boy with attention deficit disorder and academic disorder. The results of neuropsychological evaluations before and after therapy suggest improvement in executive functions and better self-esteem. Satisfaction for the boy and his family was high. Even if these results need to be replicated, cognitive remediation appears to be a new therapeutic tool, complementary to classical approaches used in childhood psychiatric disorders. The Department of Child and Adolescent Psychiatry will submit this program to a research program conducted by the National Health Department to study the impact of this approach in a controlled study.

A systematic review of cognitive remediation therapy for anorexia nervosa - development, current state and implications for future research and clinical practice

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.
