Abstract [en]

Objective: Patients with atypical anorexia nervosa (AN) are often in the normal-weight range at presentation; however, signs of starvation and medical instability are not rare. White matter (WM) microstructural correlates of atypical AN have not yet been investigated, leaving an important gap in our knowledge regarding the neural pathogenesis of this disorder.

Method: We investigated WM microstructural integrity in 25 drug-naive adolescent patients with atypical AN and 25 healthy controls, using diffusion tensor imaging (DTI) with a tract-based spatial statistics (TBSS) approach. Psychological variables related to the eating disorder and depressive symptoms were also evaluated by administering the eating disorder examination questionnaire (EDE-Q) and the Montgomery-angstrom sberg depression rating scale (MADRS-S) respectively, to all participants.

Results: Patients and controls were in the normal-weight range and did not differ from the body mass index standard deviations for their age. No between groups difference in WM microstructure could be detected.

Discussion: Our findings support the hypothesis that brain structural alterations may not be associated to early-stage atypical AN. These findings also suggest that previous observations of alterations in WM microstructure in full syndrome AN may constitute state-related consequences of severe weight loss. Whether the preservation of WM structure is a pathogenetically discriminant feature of atypical AN or only an effect of a less severe nutritional disturbance, will have to be verified by future studies on larger samples, possibly directly comparing AN and atypical AN.

Abstract [en]

OBJECTIVE: Patients with atypical anorexia nervosa (AN) have many features overlapping with AN in terms of genetic risk, age of onset, psychopathology and prognosis of outcome, although the weight loss may not be a core factor. While brain structural alterations have been reported in AN, there are currently no data regarding atypical AN patients.

METHOD: We investigated brain structure through a voxel-based morphometry analysis in 22 adolescent females newly-diagnosed with atypical AN, and 38 age- and sex-matched healthy controls (HC). ED-related psychopathology, impulsiveness and obsessive-compulsive traits were assessed with the Eating Disorder Examination Questionnaire (EDE-Q), Barratt Impulsiveness Scale (BIS-11) and Obsessive-compulsive Inventory Revised (OCI-R), respectively. Body mass index (BMI) was also calculated.

RESULTS: Patients and HC differed significantly on BMI (p < .002), EDE-Q total score (p < .000) and OCI-R total score (p < .000). No differences could be detected in grey matter (GM) regional volume between groups.

DISCUSSION: The ED-related cognitions in atypical AN patients would suggest that atypical AN and AN could be part of the same spectrum of restrictive-ED. However, contrary to previous reports in AN, our atypical AN patients did not show any GM volume reduction. The different degree of weight loss might play a role in determining such discrepancy. Alternatively, the preservation of GM volume might indeed differentiate atypical AN from AN.

Abstract [en]

Atypical anorexia nervosa (AN) has a high incidence in adolescents and can result in significant morbidity and mortality. Neuroimaging could improve our knowledge regarding the pathogenesis of eating disorders (EDs), however research on adolescents with EDs is limited. To date no neuroimaging studies have been conducted to investigate brain functional connectivity in atypical AN. We investigated resting-state functional connectivity using 3 T MRI in 22 drug-naive adolescent patients with atypical AN, and 24 healthy controls. Psychological traits related to the ED and depressive symptoms have been assessed using the Eating Disorders Examination Questionnaire (EDE-Q) and the Montgomery-Asberg Depression Rating Scale self-reported (MADRS-S) respectively. Reduced connectivity was found in patients in brain areas involved in face-processing and social cognition, such as the left putamen, the left occipital fusiform gyrus, and specific cerebellar lobules. The connectivity was, on the other hand, increased in patients compared with controls from the right inferior temporal gyrus to the superior parietal lobule and superior lateral occipital cortex. These areas are involved in multimodal stimuli integration, social rejection and anxiety. Patients scored higher on the EDE-Q and MADRS-S questionnaires, and the MADRS-S correlated with connectivity from the right inferior temporal gyrus to the superior parietal lobule in patients. Our findings point toward a role for an altered development of socio-emotional skills in the pathogenesis of atypical AN. Nonetheless, longitudinal studies will be needed to assess whether these connectivity alterations might be a neural marker of the pathology.

Abstract [en]

BACKGROUND: Management of diabetes is demanding and requires efficient cognitive skills, especially in the domain of executive functioning. However, the impact of impaired executive functions on diabetes control has been studied to a limited extent. The aim of the study is to investigate the association between executive problems and diabetes control in adolescents with type 1 diabetes.

MATERIALS AND METHODS: Two hundred and forty-one of 477 (51%) of 12- to 18-year-old adolescents, with a diabetes duration of >2 years in Stockholm, Uppsala, and Jönköping participated. Parents and adolescents completed questionnaires, including Behavioral Rating Inventory of Executive Function (BRIEF), Attention-Deficit/Hyperactivity Disorder (ADHD)-Rating Scale (ADHD-RS) and demographic background factors. Diabetes-related data were collected from the Swedish Childhood Diabetes Registry, SWEDIABKIDS. Self-rated and parent-rated executive problems were analyzed with regard to gender, glycosylated hemoglobin (HbA1c), frequency of outpatient visits, and physical activity, using chi-square tests or Fisher's test, where P-values <.05 were considered significant. Furthermore, adjusted logistic regressions were performed with executive problems as independent variable.

RESULTS: Executive problems, according to BRIEF and/or ADHD-RS were for both genders associated with mean HbA1c >70 mmol/mol (patient rating P = .000, parent rating P = .017), a large number of outpatient visits (parent rating P = .015), and low physical activity (patient rating P = .000, parent rating P = .025). Self-rated executive problems were more prevalent in girls (P = .032), while parents reported these problems to a larger extent in boys (P = .028).

CONCLUSION: Executive problems are related to poor metabolic control in adolescents with type 1 diabetes. Patients with executive problems need to be recognized by the diabetes team and the diabetes care should be organized to provide adequate support for these patients.

Abstract [en]

BACKGROUND: Adults with eating disorders (ED) show brain volume reductions in the frontal, insular, cingulate, and parietal cortices, as well as differences in subcortical regions associated with reward processing. However, little is known about the structural differences in adolescents with behavioural indications of early stage ED.

AIM: This is the first study to investigate structural brain changes in adolescents newly diagnosed with ED compared to healthy controls (HC), and to study whether ED cognitions correlate with structural changes in adolescents with ED of short duration.

METHODS: Fifteen adolescent females recently diagnosed with ED, and 28 age-matched HC individuals, were scanned with structural magnetic resonance imaging (MRI). Whole-brain and region-of-interest analyses were conducted using voxel-based morphometry (VBM). ED cognitions were measured with self-report questionnaires and working memory performance was measured with a neuropsychological computerized test.

RESULTS AND CONCLUSIONS: The left superior temporal gyrus had a smaller volume in adolescents with ED than in HC, which correlated with ED cognitions (concerns about eating, weight, and shape). Working memory reaction time correlated positively with insula volumes in ED participants, but not HC. In ED, measurements of restraint and obsession was negatively correlated with temporal gyrus volumes, and positively correlated with cerebellar and striatal volumes. Thus, adolescents with a recent diagnosis of ED had volumetric variations in brain areas linked to ED cognitions, obsessions, and working memory. The findings emphasize the importance of early identification of illness, before potential long-term effects on structure and behaviour occur.

Abstract [en]

Background: Family-based treatments are first-line treatments for adolescents with restrictive eating disorders (ED) but have to be improved since outcome is poor for some. We have investigated the one-year outcome of a family-based intervention programme with defined and decisive interventions at the start of treatment.

Method: Data pertaining 201 adolescents with restrictive ED with features of anorexia nervosa but not fulfilling the weight criterion starting treatment 2010-2015, had a wide range of body mass index (BMI) and of weight loss at presentation, and completed a one-year follow-up was analysed. Recovery from the ED was defined as an Eating Disorder Examination-questionnaire (EDE-Q) score < 2.0 or as not fulfilling criteria for an ED at a clinical interview.

Results: By EDE-Q 130 (65%) had recovered at 1 year and by clinical interview 106 (53%). According to the EDE-Q criterion recovery was independently associated with lower EDE-Q score at presentation, higher weight gain after 3 months of treatment and lower weight suppression at follow-up, weight suppression being defined as the difference between premorbid and current BMI. Not fulfilling criteria for an ED was associated with the same factors and also by higher BMI at presentation.

Conclusion: The observations that low weight and high ED cognitions confer a poor prognosis but that rapid weight gain at the start of treatment predicts a better prognosis are presently extended to adolescents with restrictive ED with a wide range of BMI at presentation. High weight suppression at follow-up is associated with a poor prognosis and indicates the importance of taking premorbid BMI into account when setting weight targets for treatment.

Abstract [en]

Few studies have used diffusion tensor imaging (DTI) to investigate the micro-structural alterations of WM in patients with restrictive eating disorders (rED), and longitudinal data are lacking. Twelve patients with rED were scanned at diagnosis and after one year of family-based treatment, and compared to twenty-four healthy controls (HCs) through DTI analysis. A tract-based spatial statistics procedure was used to investigate diffusivity parameters: fractional anisotropy (FA) and mean, radial and axial diffusivities (MD, RD and AD, respectively). Reduced FA and increased RD were found in patients at baseline in the corpus callosum, corona radiata and posterior thalamic radiation compared with controls. However, no differences were found between follow-up patients and controls, suggesting a partial normalization of the diffusivity parameters. In patients, trends for a negative correlation were found between the baseline FA of the right anterior corona radiata and the Eating Disorder Examination Questionnaire total score, while a positive trend was found between the baseline FA in the splenium of corpus callosum and the weight loss occurred between maximal documented weight and time of admission. A positive trend for correlation was also found between baseline FA in the right anterior corona radiata and the decrease in the Obsessive-Compulsive Inventory Revised total score over time. Our results suggest that the integrity of the limbic-thalamo-cortical projections and the reward-related circuitry are important for cognitive control processes and reward responsiveness in regulating eating behavior.

Abstract [en]

Aim: This study examined predictors of emergency hospitalisation of adolescent girls with restrictive eating disorders and weight loss treated by a family-based intervention programme.

Methods: We studied 339 girls aged 10-17 years treated in a specialist unit at Uppsala University Children's Hospital, Sweden, from August 2010 to December 2015. Historical weight data were obtained from school health services, and other weight data were determined at presentation. Weight controlling behaviour was recorded, and patients were evaluated using the Eating Disorder Examination Questionnaire. A family-based intervention started after assessment and the early weight gain after one week, one month and three months was assessed.

Results: There were 17 emergency admissions of 15 patients for refusing food, progressive weight loss and medical instability. Logistic regression analysis showed that emergency admissions were predicted by a low body mass index standard deviation score at presentation (odds ratio 2.57), a high rate of weight loss before presentation (odds ratio 4.38) and a low rate of weight gain at the start of treatment (odds ratio 4.59).

Conclusion: Poor weight gain at the start of a family-based intervention for adolescent girls with restrictive eating disorders predicted emergency hospital admission.

Abstract [en]

Objective: The aims of this study were to explore the factor structure of the Compulsive Exercise Test (CET) in a clinical sample of Swedish adolescents with eating disorders (ED) and to study the relationship of CET with ED cognitions, body weight and exercise frequency. Methods: The compulsive Exercise Test, the Eating Disorders Examination-Questionnaire, body mass index (BMI) and exercise frequency were available at assessment of 210 adolescents (age 14.4 +/- 1.6 years) with ED. Results: Factor analysis generated four factors with close similarity to factors previously obtained in a community sample of adolescents samples and supported the use of the original version of CET. Exercise for weight control was strongly related to ED cognitions but less to exercise frequency and BMI. Exercise for regulation of mood was related to ED cognitions and exercise frequency but not to BMI. Discussion: In adolescents with ED, different aspects of exercise are related to ED cognitions. This needs addressing in the treatment of adolescents with ED.

Abstract [en]

Objective

To study the effect of clearly defined and decisive parental interventions at the start of treatment of restrictive eating disorders (ED) in adolescents.

Method

Forty-seven adolescents with ED (anorexia nervosa = 6, bulimia nervosa = 1, EDNOS = 40) and their families participated. Parents were advised to (1) keep the adolescent home from school, (2) eat all meals together with the adolescent, (3) prevent any form of exercise, and (4) prevent vomiting during the first week of treatment. Weight change was followed up to three months and EDE-Q administered at start of treatment and at three months.

Results

Thirty (64%) of the families accomplished all four interventions during the first week of treatment. Their adolescents gained ∼1 kg of weight at one week, 2 kg at one month, and 4 kg at three months while adolescents in families who did not accomplish all four interventions gained only 1.4 kg up to three months. Scores on the EDE-Q decreased during treatment and in adolescents of families who accomplished all four interventions they were in the range of a reference population.

Discussion

Decisive parental management of eating disturbed behaviors at the start of treatment of adolescents with ED promotes later clinical outcome. The finding supports the view that family based therapies are effective in adolescent ED. Results has to be followed up for evaluation of the long term effects of this type of intervention.
