Active clinical trials for "Anorexia Nervosa"

The aim of this study is to conduct a randomized control trial (RCT) to assess the efficacy of weighted blankets (WB), on anxiety for patients with severe anorexia nervosa (AN) and avoidant restrictive food intake disorder (ARFID) in an inpatient medical setting. We hypothesize that using weighted blankets will reduce anxiety in these patient populations.

The goal of the purposed research is to extend prior work (STUDY00003758: Real-time fMRI Neurofeedback to Alter Limbic Disturbances in Anorexia Nervosa) on real-time fMRI (rt-fMRI) neurofeedback (focused on amygdala down-regulation) as an innovative neurocircuitry-targeted intervention for anorexia nervosa (AN). This project will include randomization to rt-fMRI or a sham controlled group to answer the following important unresolved question: Does a patient-led procedure aimed at altering brain activity impact limbic circuit function and key eating disorder and psychiatric symptoms in AN above the effect of a matched, but non-targeted sham condition?

The purpose of this study is to determine obsessive-compulsive symptoms and BMI changes in children and adolescents with anorexia nervosa and find out whether there is a group-level correlation between the two. We also investigate a possible link between obsessive compulsive symptoms and the psychological features of eating disorders. It is a national, academic, interventional study. The data will be acquired through questionnaires.

The purpose of this study is to investigate areas of the brain responsible for appetite regulation. More specifically, the investigators would like to study changes in brain activation, e.g., changes in blood flow and oxygen use of the brain, during two different states: Once when the participants are hungry, and once when the participants are not hungry. The aim is to find out more about the neurobiology of Anorexia and Bulimia Nervosa by comparing women who never had an eating disorder with women who have recovered from Anorexia or Bulimia Nervosa.

The occurrence of anorexia nervosa (AN) during childhood or adolescence rapidly induces starvation, stop of growth and impaired mineralization of bone tissue together with an interruption of pubertal development. These consequences are initially reversible following food intake return but can lead to a more irreversible status with low height, osteoporosis and high fracture risk. The onset of the disease more and more early in life, with the first stages of puberty suggest that these consequences will be even more severe as bone resistance will be damaged by more profound effects on bone growth as well. It is therefore critical to evaluate these bone metabolism alterations in order to better manage these patients. At every age and in every clinical circumstance either physiologic or pathologic, high resolution peripheral quantitative computerized tomography (HRpQCT) provides an evaluation of bone microarchitecture that is more informative than the global quantitative assessment given by conventional Dual Energy X-ray Absorptiometry) DEXA, with a better estimate of clinical fracture risk. Here, we propose to measure cortical parameters, such as cortical thickness which plays a key role in bone biomechanical strength in young adults aged between 20 and 30 years-old, who had developed AN as early as the during the first stages of puberty but no longer present, compared to age-and sex-matched healthy volunteers. Other micro-architectural parameters will also be studied. In an exploratory phase, we will evaluate these bone microarchitectural parameters together with bone biological turnover markers and markers of sexual maturation in adolescents or young adults 20 years-old or less, undernourished and currently managed for AN.

The goal of the present study is to investigate metabolic gut-brain signaling and the neural correlates of distraction from visual food cues in patients with Anorexia nervosa and healthy controls.

The purpose of this study is to evaluate two training methods of IPT with mental health service providers in college counseling centers.

The purpose of this study was to determine whether giving insulin like growth factor-I (IGF-I) to adolescent low weight girls is safe and whether this increases levels of bone formation markers.

OBJECTIVE: Anorexia Nervosa (AN) is a complex disorder of unknown etiology that is characterized by disordered eating behaviors and specific psychopathology. In the course of anorexia around 50% will recover in the first 10 years, 25% will continue to experience symptoms but will be able to function, and 25% will go to develop chronic course, and by definition become severe treatment resistant(Tr). There is little if anything to offer to this population where the range of treatment options is limited to weight restoration interventions. Transcranial magnetic stimulation (rTMS) is a non-invasive intervention, which presents a particular interest in people with severe TrAN, specifically because of its ability to target deeper areas of the brain, such as insula, which has been argued to be a possible trait marker for AN. METHODS: This pilot study will test the efficacy and safety of deep-rTMS delivered with the H-coil in subjects with long standing treatment resistant severe anorexia nervosa (TrAN).

Deep brain stimulacion (DBS) clinical study in the subcallosal cingulate (CSG) and accumbens nucleus (NAc) for 8 patients with treatment-refractory, cronic and severe anorexia nervosa (AN) patients. The main objective is to show efficacy and safety. Studies show that SSG and NAc are strategical targets in the pathophysiology and the hypothetical surgical treatment in AN patients. The patients distribution (4 patients in each target) it will made by the AN type and the comorbidity associated, the reasons are: 1- It is well known the comorbidity treatment imoportance in the AN evolution, 2- The two differentes types of AN have differents clinical behaviour and prognosis, 3- Studies show efficacy in TOC and DM patients with NAc DBS and in DM patients with CSG DBS. The main variable is BMI. After a 6 months stabilization evaluation phase will be followed (only in patients that have increase 10% BMI) by a double-bind, crossover phase, where patients will receive 3 months with stimulation turned on and 3 month with turned off. All patients will have a 12 months follow up. The study secondary objectives are to know the relation btween the stimulacion answer (increase 10% BMI) and the differents variables, specially AN type, associated cormobidity, selected target and preoperative MRI tractography study.
