Active clinical trials for "Bulimia"

Fitness athletes emphasize the value of staying lean, muscular and defined, and motivates and inspires followers through social media. We want to study the effect of such lifestyle on selected aspects of psychological and physical health in female fitness athletes, and compare the outcomes to a healthy, physically active female population.

This study will investigate neural activation patterns in emotion- and cognition-related brain regions during an emotion regulation task involving cognitive reappraisal, and their associations with age and pubertal status, among overweight children and adolescents with loss of control eating as compared to overweight and normal-weight controls.

Loss of control (LOC) eating in children is associated with multiple physical and mental health impairments, including obesity and eating disorders. Little is known about the developmental neurobiology of LOC, which is crucial to specifying its pathophysiology and the development of effective preventive interventions. Individual differences in working memory (WM) appear to be related to LOC eating and excess weight status in youth, but the specificity and neural correlates of these individual differences are unclear. Failure to adequately understand the nature of associations between WM and eating behavior in children with overweight/obesity limits the development of appropriately-targeted, neuro-developmentally informed interventions addressing problematic eating and related weight gain in youth. To close this clinical research gap, the current study proposes to investigate the context-dependence of WM impairment and its neural correlates in children with concomitant overweight/ obesity and LOC eating as compared to their overweight/obese peers. Specific aims are to investigate: 1)WM performance in youth with LOC eating relative to overweight/obese controls during recalls in the context of food-related versus neutral distractors; and 2) neural activation patterns during WM performance across both food-related and neutral stimuli. We hypothesize that, relative to their overweight/obese peers, youth with LOC eating will show 1) more errors and slower response times during recalls involving food-related vs. neutral distractors, and fewer errors and faster response times during recalls involving food-related vs. neutral targets; 2) increased activation in prefrontal regions during WM performance across stimuli types relative to overweight/obese controls, and 3) even greater activation in the context of food-related versus neutral distractors. The proposed study is the first to use state-of-the-science neuroimaging methodology to clarify the relations between WM and LOC eating, with strong potential to advance understanding of the associations among executive functioning, excess weight status, and eating pathology, and inform the development of interventions (e.g., WM training) to alleviate their cumulative personal and societal burden.

A technique that has been found to be effective at relieving the physical and psychological symptoms associated with inhibiting emotions and emotional thoughts is written emotional disclosure. The goal of this study is to evaluate the effectiveness of written emotional disclosure on the remediation of eating disorder behaviour, cognitions, and management of emotions.

This study will determine whether the disturbances in cholecystokinin release and gastric emptying that occur in people with binge eating disorder are similar to those that occur in people with bulimia nervosa.

The purpose of this open-label, pilot study is to evaluate fMRI as a biomarker of opioid antagonism in adolescents with ED. Modulation of brain activation will be examined in regions of interest by fMRI using a food-specific and general reward task in adolescents with ED in a pre/post design.

The purpose of this study is to understand users' experiences and interests completing self-tracking in a mobile intervention for binge eating and weight management.

This study will evaluate the extent to which we can engage and manipulate putative targets within the self-regulation domain within and outside of laboratory settings in samples of smokers and overweight/obese individuals with binge eating disorder. This is the fourth phase of a study that aims to identify putative mechanisms of behavior change to develop an overarching "ontology" of self-regulatory processes.

The aim of this study was to investigate the difference between electroencephalography (EEG) data and current psychological status of individuals diagnosed with anorexia nervosa (AN) and bulimia nervosa (BN).

To determine whether reducing loss of control eating (LOC) with Interpersonal Psychotherapy-Weight Gain (IPT-WG) will be effective for adolescent military-dependents who report such behavior. The investigators will examine whether IPT-WG influences body weight gain trajectories and prevents worsening disordered eating, psychosocial problems, and metabolic functioning among military dependents at heightened risk for adult obesity and disordered eating. This study will provide key efficacy data for a new promising obesity prevention program for youth from military families.
