The Effects of Repetitive Transcranial Magnetic Stimulation in Obese People With BED
Binge EatingObesityThe presence of binge eating (BE) is a core feature of bulimic syndromes. Binge eating disorder (BED) is a new category in DSM-5 highly associated with higher body mass index (BMI). The neural mechanisms that underlie BE are of great interest in order to improve treatment interventions. Brain mechanisms underlying drug and food craving are suggested to be similar. These mechanisms demonstrated hyperactivity in the orbitofrontal and anterior cingulate cortex and lack of regulatory influence from lateral prefrontal circuits. Several novel studies began to assess the potential benefits of brain stimulation in reducing craving and associated addictive behaviors with promising results. Previous findings testing a one-off session of repetitive transcranial magnetic stimulation (rTMS) in healthy women identified as strong cravers and individuals with bulimia nervosa or bulimic-type eating disorders reported reduction of food craving and BE, providing evidence to support a broader and deeper investigation of the benefits associated with rTMS. Importantly, the use of brain imaging studies contributes to the understanding of psychiatric disorders and underlying mechanisms being target by the rTMS intervention. Objectives: The primary aim is to investigate the effects of rTMS over BE frequency. Secondary aims include the evaluation of the effects of rTMS on food craving, body weight, brain activity, cognition, general psychopathology, hormonal regulation and neurobiological markers. Methods: Sixty obese females with BED will be randomized to receive 20 sessions of rTMS (n=30) or placebo (n=30) scattered 3 days/week. Expected Results: Primarily it is expected that rTMS intervention will decrease BE frequency. Consequently, body weight will be reduced. It is also expected that food craving be decreased, cognitive performance be enhanced, and neurobiological markers be improved.
Guided Self-Help for Binge Eating Disorder
Binge Eating DisorderThe proposed study will employ a randomized design to evaluate the efficacy of two group-based guided self-help treatments: Integrative Response Therapy (IRT) and Cognitive Behavior Therapy Guided Self-Help, a treatment of known efficacy, in group-format (CBT-GSHg) in the treatment of Binge Eating Disorder (BED), and explore (1) moderators and mediators of treatment, (2) the relative cost-effectiveness of the two treatments, and (3) between group differences on secondary measures (e.g., eating disorder and general psychopathology).
Cholecystokinin for Reducing Binge Eating in People With Bulimia Nervosa
Bulimia NervosaEating DisordersThis study will determine the effectiveness of administrating a dose of cholecystokinin during a binge eating episode in reducing this eating behavior in people with bulimia nervosa.
Zonegran in the Treatment of Binge Eating Disorder Associated With Obesity
Binge Eating Disorder Associated With ObesityThe specific aim of this study is to examine the efficacy and safety of zonisamide compared with placebo in outpatients with binge eating disorder associated with obesity.
Meditation-Based Treatment for Binge Eating Disorder
Binge Eating DisorderObesityThe purpose of this study is to assess the relative effectiveness of a mindfulness meditation-based intervention for binge eating disorder in comparison to a psycho-educational intervention and a waiting-list control group.
Project BITE: Binge Intervention Target Effectiveness
Binge-Eating DisorderThe primary aim of this study is to determine how inhibitory neurobiological and neurocognitive processes relate to binge eating treatment outcome.
An Open Label Trial of Memantine in the Treatment of Bulimia Nervosa and Body Dysmorphic Disorder...
Bulimia NervosaBody Dysmorphic DisorderThe primary objective of this 13-week clinical trial is to test the hypothesis that treatment with Memantine will significantly improve the symptoms of those suffering from either bulimia nervosa, purging type or suffering from body dysmorphic disorder.
Online Cognitive Behavioral Therapy for Bulimia Nervosa
Bulimia NervosaCognitive Behavioral Therapy for Bulimia Nervosa (CBT4BN) is a research program funded by the National Institute of Mental Health and conducted by the UNC Eating Disorders Program and the University of Pittsburgh Medical Center. Cognitive Behavioral Therapy (CBT) is an evidence-based treatment and the gold-standard for treating bulimia nervosa. The current study aims to compare two forms of CBT: face-to-face group therapy and online group therapy via cbt4bn.org.
Treatment of Binge Eating Disorder
BulimiaObesityThis is a multicenter (2 sites) randomized trial evaluating three group treatment models for subjects with binge eating disorder. One model is a cognitive behavior treatment (CBT) group, one is partial self help, and one is self help only.
Comparing a Group-based Guided Self-help Approach to Pure Self-help for the Treatment of BED
Binge Eating DisorderBinge eating disorder (BED) is the most common eating disorder in adults, affecting 2.8% of the population. The disorder is characterized by recurrent episodes of binge eating which are not followed by inappropriate compensatory behaviours such as self-induced vomiting. BED is associated with an increased risk of health complications, significant impairment to social and occupational functioning, and reduced quality of life. Despite the negative consequences associated with this disorder, standard therapy for BED is often inaccessible and costly. To address the limitations of standard therapy for BED our research team has developed Binge Focused Therapy (BFT) as an innovative, guided self-help approach to BED treatment. BFT was derived from elements of "The Brain Over Binge Recovery Guide" by Kathryn Hansen, which incorporates fundamental aspects of Acceptance and Commitment Therapy, Dialectical Behaviour Therapy, Motivational Enhancement Therapy, and addictions treatment. We further streamlined this approach into a protocol that can be delivered by non eating disorder specialists (e.g., honours psychology students, nurses, occupational therapists). In 2018, our research team conducted a proof-of-concept pilot study with a sample of 40 individuals with BED. Unpublished results of this uncontrolled study indicated that the sample experienced significant reductions in binge episodes per month, binge eating severity, general eating disorder symptomology, and improved confidence in changing binge eating behaviours. Although the results from this small, uncontrolled, proof-of-concept study are encouraging, qualitative and quantitative data highlighted several aspects of the BFT intervention that could be altered and tested in a randomized controlled trial that compares BFT to an active comparator.
