Associations between neuropsychological performance and appetite-regulating hormones in anorexia nervosa and healthy controls: Ghrelin's putative rol…

2019

Anorexia nervosa (AN) is a severe eating disorder accompanied by alterations in endocrinological circuits and deficits in neuropsychological performance. In this study, a series of appetite-regulating hormones (ghrelin, leptin, cholecystokinin, PYY, adiponectin, and visfatin) were measured under fasting conditions in female patients with AN and female healthy controls. All of the participants also underwent a battery of neuropsychological assessment [namely the Iowa Gambling Task (IGT), the Wisconsin Card Sorting Test (WCST), and the Stroop Color and Word Test (SCWT)]. As the main finding, we found that higher ghrelin levels predict better performance in the IGT. Ghrelin may be a putative m…

Changes in the Peripheral Endocannabinoid System as a Risk Factor for the Development of Eating Disorders

2017

BACKGROUND AND OBJECTIVE Eating Disorder (ED) is characterized by persistently and severely disturbed eating behaviours. They arise from a combination of long-standing behavioural, emotional, psychological, interpersonal, and social factors and result in insufficient nutrient ingestion and/or adsorption. The three main EDs are: anorexia nervosa, bulimia nervosa, and binge eating disorder. We review the role of peripheral endocannabinoids in eating behaviour. DISCUSSION The neuronal pathways involved in feeding behaviours are closely related to catecholaminergic, serotoninergic and peptidergic systems. Accordingly, feeding is promoted by serotonin, dopamine, and prostaglandin and inhibited b…

Direct Experience While Eating in a Sample With Eating Disorders and Obesity

2018

Background: Individuals with eating disorders might be characterized by lower levels of direct engagement with the eating experience. This study aims to explore similarities and differences in direct experience while eating in four different weight conditions and healthy controls (HCs): anorexia nervosa (AN), bulimia nervosa (BN), eating disorders not otherwise specified (EDNOS), and obesity (OB). Methods: A total sample of 143 women were recruited. Participants were asked to eat an orange slice and write down 10 things about the experience of eating, classifying the focus of these thoughts as either experiential (“direct experience”) or analytical (“thinking about”). A direct experience in…

Momentary emotion identification in female adolescents with and without anorexia nervosa.

2017

Individuals with anorexia nervosa (AN) often report difficulties in identifying emotions, which have been mostly studied as an alexithymia trait. In a controlled two-day ecological momentary assessment, we studied the influence of time of day and aversive tension on self-reported momentary emotion identification. Analysis on an aggregated level revealed a significant lower mean emotion identification in the AN group. In a mixed model analysis, the AN group showed lower emotion identification than the control group (HC). Both a general and a group effect of time of day were found, indicating that emotion identification improved during the day in HC, whereas a negligible decrease of the emoti…

Effects of stress on chewing and food intake in patients with anorexia nervosa

2021

OBJECTIVE The present study investigates the impact of psychosocial stress on chewing and eating behavior in patients with anorexia nervosa (PAN ). METHOD The eating and chewing behavior of PAN were examined in a standardized setting by means of a chewing sensor. These procedures encompassed n = 19 PAN , age, and gender matched to n = 19 healthy controls (HC). Food intake and chewing frequency were assessed in two experimental conditions: rest versus stress (via Trier Social Stress Test). To verify stress induction, two appraisal scales were employed. In addition, chronic stress, psychological distress and eating disorder symptoms were assessed. RESULTS In terms of food intake and chewing f…

Social Difficulties As Risk and Maintaining Factors in Anorexia Nervosa: A Mixed-Method Investigation

2018

Anorexia nervosa (AN) is a serious psychiatric disorder characterized by severe restriction of energy intake and dangerously low body weight. Other domains of functioning are affected, including social functioning. Although difficulties within this domain have started to be acknowledged by the literature, some important gaps remain to be filled. Do social difficulties predate the onset of the illness? What difficulties in particular are relevant for the development and maintenance of the illness? The aim of this study is to combine the use of quantitative and qualitative methods to answer these questions. Ninety participants with lifetime AN (88 women and 2 men) completed an online survey a…

Perfectionism, a Transdiagnostic Construct In Eating Disorders

2016

IntroductionPerfectionism is considered a multidimensional key risk factor for Eating Disorders (EDs). There are discrepancies regarding if it is mainly associated to Anorexia nervosa (AN) but not to other EDs.ObjectivesTo study if Perfectionism is not only related with AN, but it is present in all EDs and associated with more transdiagnostic attitudes and behaviors.AimsTo see if there were significant differences among EDs subgroups concerning Perfectionism and to study which abnormal eating attitudes were more associated with this trait.MethodsParticipants were 151 outpatients with EDs. DSM-IVTR diagnoses were: 44 (29.1%) Anorexia Nervosa (AN), 55 (36.4%) Bulimia Nervosa (BN) and 52 (34.4…

Objectives Investigating for the first time in Germany Diagnostic and Statistical Manual Fifth Edition (DSM-5) prevalences of adolescent full syndrome, Other Specified Feeding or Eating Disorder (OSFED), partial and subthreshold anorexia nervosa (AN), bulimia nervosa (BN) and binge eating disorder (BED). Method A national school-based cross-sectional survey with nine schools in Germany was undertaken that was aimed at students from grades 7 and 8. Of the 1775 students who were contacted to participate in the study, 1654 participated (participation rate: 93.2%). The sample consisted of 873 female and 781 male adolescents (mean age=13.4 years). Prevalence rates were established using direct s…

Blunted Cortisol Awakening Response and Poor Self-Perceived Health in Informal Caregivers of People with Eating Disorders

2016

Caring for offspring diagnosed with eating disorders (EDs) entails being under high chronic stress, with negative consequences for health. However, most previous research has only evaluated self-report measures of health, biological markers being poorly studied. In this regard, the evaluation of the cortisol awakening response (CAR) could add significant information about the biological basis of health disturbances in this population. The main aim of the present study was to compare CAR and self-reported health between informal caregivers (ICs) of people with EDs and non-caregivers. Furthermore, we explored the effect of the nature of the diagnosis, comparing ICs of people with anorexia and…
