Bulimia nervosa

Trevor Steward, José M Menchón, Susana Jiménez-Murcia, Carles Soriano-Mas, Fernando Fernández-Aranda
Functional magnetic resonance imaging (fMRI) has provided insight on how neural abnormalities are related to the symptomatology of the eating disorders (EDs): anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED). More specifically, an increasingly growing number of brain imaging studies has shed light on how functionally connected brain networks contribute not only to disturbed eating behavior, but also to transdiagnostic alterations in body/interoceptive perception, reward processing and executive functions...

OBJECTIVE: This study was to model the cost-effectiveness of specialist-delivered cognitive behavioral therapy for bulimia nervosa (CBT-BN) compared to no intervention within the Australian context. METHOD: An illness-death model was developed to estimate the cost per disability-adjusted life-year (DALY) averted of CBT-BN over 2 years from the healthcare perspective. Target population was adults aged 18-65 years with BN. Results are reported as incremental cost-effectiveness ratios (ICER) in 2013 Australian dollars per DALY averted...

OBJECTIVE: Longitudinal studies support a prospective relationship between weight suppression (WS) and bulimic syndrome (BN-S) maintenance. Although biobehavioral mechanisms have been proposed to explain this link, such mechanisms have yet to be identified. Given that weight loss would reduce leptin levels which may influence eating, this study examined whether reduced leptin levels mediate the link between greater WS and longer illness duration. METHOD: Women (N = 53), ages 18-45 years, were recruited from the community if they met criteria for a BN-S, including either DSM-5 bulimia nervosa (BN; n = 33) or purging disorder (PD: n = 20), and fell within a healthy weight range (18...

OBJECTIVE: Several overlapping cognitive processes have been identified in eating disorders (EDs) and obsessive compulsive disorder (OCD). Drawing from the OCD literature, the present study examined whether bulimia nervosa (BN) is associated with a maladaptive inductive reasoning style characterized by the over-investment in possibility-based (as opposed to reality-based) information. METHOD: Women with BN (n = 25) and healthy controls (HC; n = 24) completed the Inference Processes Task (IPT), an ecological inductive reasoning task previously validated in OCD samples...

BACKGROUND: There is little effective psychopharmacological treatment for individuals with eating disorders who struggle with pervasive, severe affective and behavioral dysregulation. METHODS: This pilot open series evaluated lamotrigine, a mood stabilizer, in the treatment of patients with eating disorders who did not respond adequately to antidepressant medications. Nine women with anorexia nervosa- or bulimia nervosa-spectrum eating disorders in partial hospital or intensive outpatient dialectical behavior therapy (DBT)-based eating disorder treatment took lamotrigine for 147 ± 79 days (mean final dose = 161...

Research has studied family functioning in families of patients suffering from eating disorders (EDs), particularly investigating the associations between mothers' and daughters' psychopathological symptoms, but limited studies have examined whether there are specific maladaptive psychological profiles characterizing the family as a whole when it includes adolescents with anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED). Through the collaboration of a network of public and private consultants, we recruited n=181 adolescents diagnosed for EDs (n=61 with AN, n=60 with BN, and n=60 with BEDs) and their parents...

INTRODUCTION: Bulimia nervosa (BN) and binge eating disorder (BED) are associated with severe psychological and medical consequences. Current therapies are limited, leaving up to 50% of patients symptomatic despite treatment, underscoring the need for additional treatment options. Qsymia, an FDA-approved medication for obesity, combines phentermine and topiramate ER. Topiramate has demonstrated efficacy for both BED and BN, but limited tolerability. Phentermine is FDA-approved for weight loss...

BACKGROUND: The objective of the study was to determine whether levels of biochemical and haematological parameters in patients with eating disorders (EDs) varied from the general population. Whilst dietary restrictions can lead to nutritional deficiencies, specific abnormalities may be relevant to the diagnosis, pathogenesis and treatment of EDs. METHODS: With ethics approval and informed consent, a retrospective chart audit was conducted of 113 patients with EDs at a general practice in Brisbane, Australia...

The aim of this study was to examine differences in brain neural activation in response to monosodium glutamate (MSG), the representative component of umami, between patients with bulimia nervosa (BN) and healthy women (HW) controls. We analyzed brain activity after ingestion of an MSG solution using functional magnetic resonance imaging (fMRI) in a group of women with BN (n = 18) and a group of HW participants (n = 18). Both groups also provided a subjective assessment of the MSG solution via a numerical rating scale...

OBJECTIVE: Child maltreatment is associated with an increased likelihood of having mood disorders, anxiety disorders, post-traumatic stress disorder, substance use disorders, and personality disorders, but far less is known about eating disorders. The objective of the current study was to examine the associations between child maltreatment, including harsh physical punishment, physical abuse, sexual abuse, emotional abuse, emotional neglect, physical neglect, and exposure to intimate partner violence, and eating disorders in adulthood among men and women...

Grazing, the unstructured, repetitive eating of small amounts of food, is a pattern of eating which has been associated with negative outcomes following bariatric surgery. Less is known about grazing in eating disorders and in non-surgical obese samples. This review aims to critically examine the existing research on the prevalence of grazing, associated treatment outcomes, and clinical correlates in adults with eating disorders and/or obesity, in clinical and community settings. A systematic electronic database search yielded 38 studies which met inclusion criteria for the review...

Eating disorders are a potentially life-threatening group of mental disorders, which affect a patient's relationship with food and their body. This manifests itself through chaotic and disordered eating habits. One such eating disorder is bulimia nervosa, which has a lifetime prevalence of 1%. While there is consensus that bulimic behaviour directly causes dental erosion due to vomiting and acidic food choices, there is less clear evidence for a direct link between bulimia nervosa and dental caries, although there does still appear to be an association...

Body image avoidance is conceptualised as a behavioural manifestation of body image disturbance, and describes efforts to avoid confrontation with one's own body. While studies have provided hints that body image avoidance in adulthood contributes to the development and maintenance of eating disorders, so far, there are no corresponding findings for adolescence. The Body Image Avoidance Questionnaire (BIAQ) is the most widely used international questionnaire for measuring body-related avoidance behaviour. As its German version has only been validated in an adult sample, the aim of the present study is to statistically test the questionnaire in adolescents with eating disorders...

Social cognition has been studied extensively in anorexia nervosa (AN), but there are few studies in bulimia nervosa (BN). This study investigated the ability of people with BN to recognise emotions in ambiguous facial expressions and in body movement. Participants were 26 women with BN, who were compared with 35 with AN, and 42 healthy controls. Participants completed an emotion recognition task by using faces portraying blended emotions, along with a body emotion recognition task by using videos of point-light walkers...

OBJECTIVE: Guided self-help treatments based on cognitive-behavior therapy (CBT-GSH) are efficacious for binge eating. With limited availability of CBT-GSH in the community, mobile technology offers a means to increase use of these interventions. The purpose of this study was to test the initial efficacy of Noom Monitor, a smartphone application designed to facilitate CBT-GSH (CBT-GSH + Noom), on study retention, adherence, and eating disorder symptoms compared to traditional CBT-GSH...

BACKGROUND: Eating disorders (EDs) are serious mental illnesses of growing clinical and social impact. Despite their severity, there is still no satisfactory evidence-based treatment. Follow-up investigations are the most reliable studies to enlighten long-term outcome predictors and modifiers. METHODS: In total, 59 subjects affected with anorexia nervosa were assessed 8 years after their admission into an outpatient multimodal treatment program for eating disorders...

BACKGROUND: The aims of this study were to analyse the quality of life (QoL) of a broad sample of patients with eating disorders (ED) and to identify potential factors that predict QoL. METHODS: This prospective cohort study involved 528 patients diagnosed with ED and treated over a 15-year period in the Eating Disorders Outpatient Clinic. Information on sociodemographic and clinical data were gathered. Patients completed five self-administered instruments: the Eating Attitudes Test-26 (EAT-26); the Eating Disorder Diagnostic Scale (EDDS); the Hospital Anxiety and Depression Scale (HADS); the Short-Form 12 (SF-12); and the Quality of Life in ED-short form (HeRQoLED-s)...
