Filter by:Patients with anorexia nervosa (AN), a serious psychiatric disorder, exhibit restricted dietary intake and endorse fear of consuming calorie-dense foods, which in turn drives weight loss. Premorbid anxious personality traits and comorbid anxiety disorders are common in patients with AN. Although intensive behavioral treatment programs can achieve weight restoration in a majority of adults with AN, relapse rates are high. Predictors of relapse include elevated state anxiety and low dietary variety, including lower intake of fat, after discharge, which suggests that relapse following weight restoration may be related to inadequate fear extinction to high energy density (ED) foods during treatment and consequent resumption of restrictive eating patterns. Despite evidence of anxiety's role in the onset and maintenance of restricted eating behavior, utilizing exposure and response prevention (EX-RP) and meal-based interventions to reduce food-related fears is understudied. EX-RP is the gold standard of treatment for Obsessive Compulsive Disorder (OCD). This proposal aims to test the efficacy of an adjunct meal-based EX-RP intervention to reduce food-related fears during intensive behavioral weight restoration in hospitalized patients with AN in comparison to a control treatment, Motivational Interviewing. The investigators will assess changes in a) self-reported anxiety regarding consumption of high-ED foods, b) physiological (skin conductance and heart rate variability) responses to imagined consumption of food items elicited utilizing a visual food cue task, and c) caloric intake of a challenging test meal pre- and post-treatment. A secondary aim is to assess the relationship of early treatment response to EX-RP, operationalized as a reduction in self-reported anxiety within the first three weeks of treatment, and end-of-treatment as well as six-month post-discharge outcomes. Helping patients tolerate food-related anxiety and increase dietary variety across meal contexts may augment treatment effectiveness in adult patients during intensive treatment for AN and has potential to decrease relapse rates.
This study evaluates if imaginal exposure therapy can decrease symptoms of eating disorders and anxiety, and test an online format of IE to maximize its ability to reach as many individuals with eating disorders as possible. All participants will complete four imaginal exposure sessions and will complete questionnaires prior to receiving this treatment, as well as complete follow up questionnaires at 1-month, 6-month, and 12-month.
A growing qualitative literature about personal recovery process in mental disorders emerges. However in Anorexia Nervosa (AN), it remains few understood, especially in severe AN during adolescence. This pilot study seeks to enhance understanding of recovery from AN in France and support the dissemination of the PR paradigm among the French mental health community working with AN, as a complement to the medical approach. A qualitative research according to Interpretative Phenomenological Analysis (IPA) method was conducted .Five young women hospitalized ten years before for a severe AN during their adolescence were interviewed with a semi-structured face-to-face interview on recovery process.
To improve treatment for patients with severe anorexia nervosa admitted for inpatient care, and to help their families. Inpatients and their families will be offered a novel intervention which includes multimedia training materials. These materials provide guidance in how families can provide support to maintain and build on changes made during inpatient care
A randomized, controlled, three-arm study to investigate the effects of footbaths with ginger, mustard or warm water alone in female, adolescent patients with Anorexia nervosa and in healthy, female adolescents on psychophysiological parameters.
Restrictive anorexia nervosa and TOCs are psychiatric diseases which shares a common pathophysiological substrate We hypothesize that anorexia patients and patients with OCD have structural and functional changes in the accumbofrontal tract. The main objective of this study will be to compare the structure and the connectivity of this tract in MRI with diffusion sequences (DTI tractography) and resting-state, in 3 distinct populations of anorexic patients, patients with OCD and healthy patients. The role of the accumbo-frontal tract in the cortico-striato-hypothalamo-cortical circuit seems to be established. DTI tractography will allow the measurement of functional anisotropy (FA), a parameter that evaluates the diffusion of water molecules along the white matter fibers, and therefore the potential alteration of the studied tract. Resting state sequences will allow to estimate the BOLD signal and the functionality of the tract.
In-patients with severe anorexia nervosa (AN) often drop out of treatment, because of ambivalence towards treatment and anxiety for weight gain. However, physical therapy has shown some positive effects on symptoms of AN. This study aims to investigate the feasibility of a randomized control trial (RCT) of a standardized physiotherapeutic program for patients with severe AN with compliance to nutritional therapy as the primary outcome measure.
This study uses a computational task to examine differences in adaptive learning to both rewards and punishments between three groups: those who have recovered from anorexia nervosa, those who score highly on the EAT-26 (Eating Attitudes Test - 26 item version; an eating disorder symptom scale), and healthy controls. This task also allows the examination of pupil response (thought to reflect norepinephrine activity) in response to expected and unexpected wins and losses.
The investigators will examine compulsivity in those who have recovered from anorexia nervosa, using a multi-modal MRI study. The neural activation of key fronto-striatal areas will be explored using a task which examines set-shifting and reversal-learning, two key components of compulsivity. Additionally, the functional networks displayed during resting-state MRI will be examined between groups, as will the neurochemicals present (using Magnetic Resonance spectroscopy).
This study will use a randomized, controlled, double-blind design involving the administration of intranasal oxytocin (INOT) or placebo to adults with anorexia nervosa, restricting subtype and age-matched controls prior to neuroimaging to assess the impact on frontolimbic brain activity in response to socioemotional stimuli as well as eating behavior in a test meal paradigm.
