Filter by:This pilot study examines the effect of stabilizing ovarian hormones on eating behaviors and brain activation in women with binge eating (n=15) using functional magnetic resonance imaging (fMRI) and behavioral tests. This is completed by taking oral contraceptives (birth control) continuously for three months. Prior to medication administration and at the end of treatment, eating behaviors will be measured and fMRI will be conducted in order to examine changes in activation in dopamine-reward pathways that occur with oral contraceptive administration. This will assess changes in brain activation that occur with the stabilization of ovarian hormones.
This study will investigate the effect of lisdexamfetamine dimesylate (LDX) on the mediating factors of reward and cognition on appetite.
This trial is a set of four independent experiments involving for each of them functional and structural MRI data acquisition. They aim at investigating decision making mechanisms in bulimia nervosa when participants have to make food or monetary choices under specific conditions that mimic binge eating episodes or kleptomania which are two major symptoms of bulimia nervosa. All experiments are cross sectional studies. Each experiment is subdivided into two parts: a first part without any MRI data acquisition and during which all the tasks are performed. This part aims at making sure that a behavioral effect is observed before starting MRI data acquisition. The second part aims at investigating the neural correlates observed in the first part and additionally, at reproducing the behavioral effects observed in the first part. Therefore the first part may be regarded as an independent study as compared to the second part.
This study aims to perform an open-series pilot trial to examine the efficacy of cognitive-behavioral therapy delivered in a guided self-help format (CBTgsh) with added content related to physical activity (PA), for the treatment of binge-eating disorder (BED), operationalized as BED full diagnostic criteria or BED with the full criteria except for the binge episode size criterion.
The purpose of the proposed study is to pilot a 6-month, cognitive-behavioral binge eating intervention, Appetite Awareness Training (AAT) to reduce binge eating and prevent weight gain for Black women with a BMI > 25 kg/m^2 and with weekly binge eating episodes. Intervention participants will receive a 8-week group AAT intervention, and will also receive bluetooth-connected scales for daily weighing. Participants will also receive tailored feedback on self-weighing frequency and weight change. The investigators will follow-up with participants at six months.
There are limited evidence-based treatments for adolescents with binge eating and fewer specifically targeting adolescents with both binge eating and overweight/obesity. The existing research for adolescents with overweight/obesity and loss of control (LOC) eating supports a stepped-care model of treatment in which enhanced behavioral weight loss treatment is the first line of treatment followed by more intensive therapeutic treatment for individuals with remaining emotional eating difficulties. Thus, in this proposed study, the investigators will systematically develop a stepped-care protocol and manualized interventions for adolescents with LOC and binge eating behaviors. The investigators will then evaluate the feasibility and acceptability of the interventions in a pilot trial and gather preliminary outcome data to inform development of a subsequent randomized controlled trial.
The relatively high rates of bulimia nervosa (BN) in attention-deficit/hyperactivity disorder (ADHD) cohorts suggest a relationship between the two disorders. Interestingly, case studies involving this comorbid population have observed improvements in BN symptoms when given psychostimulants for ADHD. Case studies involving BN patents without this comorbidity have also demonstrated BN symptom improvements upon psychostimulant initiation. Recent studies have also found support for the use of lisdexamfetamine dimesylate, a psychostimulant approved for ADHD, for treating moderate to severe binge eating disorder, an eating disorder akin to BN. Given these findings, there is reason to believe that psychostimulants may also be capable of treating bulimia nervosa. Ultimately, the investigators would like to conduct a large study that examines whether people who are diagnosed with BN will have fewer episodes of binge eating and purging when they are treated with the psychostimulant medication, lisdexamfetamine dimesylate (LDX). However, preliminary data would be helpful prior to undertaking such a large project. To this end, the aim of the current study is to learn more about a) enrolment rates, b) dropout rates, c) the applicability of our eligibility criteria, d) the potential effects of LDX on novel outcome measures for studying decision-making in BN, e) preliminary safety data, and f) estimates of treatment effect. Participants (n = 30) will be instructed to take LDX once daily for two months while undergoing routine testing and monitoring to gather preliminary safety and treatment data. The research will take place at the Nova Scotia Health Authority Eating Disorder Clinic.
The study is a 17-week, single-center, double-blind, parallel-group, randomized placebo controlled trial that will test the efficacy of liraglutide 3.0 mg/d as compared to placebo in reducing the number of binge episodes per week, achieving remission from binge episodes, and in changes in body weight, global BED symptom improvement, cognitive restraint of food intake, dietary disinhibition, perceived hunger, quality of life, and depressed mood at treatment end.
This study will examine the effectiveness of food response training interventions in reducing binge eating among adults engaged in binge eating.
This trial will compare the efficacy and tolerability of 10 Hz vs. 1 Hz vs. sham repetitive transcranial magnetic stimulation targeting the dorsomedial prefrontal cortex, delivered once daily over 30 days, in patients with a diagnosis of bulimia or anorexia nervosa binge-purge subtype. The trial will include structural and functional MRI, and behavioral measures obtained before, during, and after treatment.
