Filter by:In the Region Skåne in Sweden, the investigators have developed guidelines for providing intensive and evidence-based treatment during the first month in case of severe restrictive eating disorder with pronounced starvation. The project is aiming at implementing this treatment program in the general Child Psychiatric clinic, with its main focus on the implementation of evidence based family therapy. The study aims to evaluate the implementation of a standardized treatment model during the first month. The outcome will be compared with the patients and families who have been in treatment before the ROCKETLAUNCH project started.
This open-label pilot study seeks to investigate the safety and efficacy of psilocybin in persons with chronic anorexia nervosa (AN). Psilocybin has previously been demonstrated to decrease depression and anxiety and increase long-term positive behavior change in other populations. The investigators seek to determine whether similar changes can be safely produced in people with AN when psilocybin is administered in a supportive setting with close follow-up. The investigators' primary hypotheses are that psilocybin is safe to administer in people with AN, that it will reduce measures of anxiety and depression, and that it will lead to increased quality of life. The investigators will also assess a number of exploratory measures related to eating disorder pathophysiology.
The proposed study of adolescents with anorexia nervosa (AN) will examine the association of behavioral differences in constructs of decision making, brain structure and connectivity, and eating disorder (ED) symptoms. This study tests the novel hypothesis that goal-directed and habit learning for reward and punishment is altered in AN and is uniquely associated with divergent symptoms and differences in corticostriatal connectivity and microstructural integrity. We will recruit 78 females currently ill with AN and 26 controls ages 13-17 to investigate how goal-directed and habit learning for reward and punishment correspond to 1) clinical symptoms collected via interviews, self-report assessments, and ecological momentary assessment (EMA), and 2) brain structure and connectivity in the resting state. Data collection will rely on a technology called functional magnetic resonance imaging (fMRI).
The hospitalization in patients with anorexia nervosa has often a short-term success, as weight is restored to a healthy level, but high percentage of patients relapse during the first year following the discharge. Starting from the observation that the relapse rate is lower in outpatient than in inpatient settings, the investigators hypothesized that the reason of this difference is the nature of inpatient treatment and post-inpatient therapy. For this reason, different procedures and strategies have been implemented during hospitalization to reduce the relapse after discharge. The aim of the study was to assess the time and the percentage of relapse after inpatient discharge and at follow-up.
In order to explore the cognitive treatment of patients with early onset anorexia nervosa (AM) in front of images of silhouettes and food, we will use the eye-tracking method. While we hypothesize a judgment disorder in these patients, the exploration of implicit cognitive treatment without desirability bias is essential. Eye-tracking is a method of recording the eye path that provides qualitative and quantitative information on the visual exploration of subjects. The visual pathway depends on how the subject's attention is directed to a given stimulus, but also on certain cognitive traits (e.g., excessive attention to details) or symptoms (e.g., avoidance of caloric food images or attraction to thin images). It is therefore a non-invasive exploration tool, which provides information on how patients look at food images and silhouettes. This project will describe the cognitive treatment of dietary stimuli and body image in young patients with early onset AM. It could identify a biomarker of AM in the pediatric population and improve the diagnosis of the disease. A better diagnosis of AM in patients under 15 years of age is essential and will improve medical care and develop personalized medicine.
The main aim of this study is to develop a virtual reality (VR) embodiment-based exposure technique to improve the treatment of anorexia nervosa (AN). A systematic and hierarchical body exposure intervention in which the patient owns a virtual avatar is proposed. At first, the virtual body matches with the real measurements of the patient, then the experimenter will progressively increase Body Mass Index (BMI) values of the virtual body during the exposure sessions until a healthy BMI value is reached (e.g. BMI score of 20). In this study a VR embodiment-based technique that combines visuo-motor and a visuo-tactile stimulation procedures is proposed in order to increase illusory feelings of ownership over the virtual body. It is hypothesised that adding a VR-based body exposure intervention to the classical cognitive behavioral therapy (CBT) will significantly reduce symptomatology in AN patients.
This study will assess the affects of an estradiol hemihydrate transdermal system on bone health in 24 adolescent females aged 12-19 years old with anorexia nervosa. Participants in this study will be randomized 1:1 into 2 groups. One group will receive treatment with a transdermal estrogen patch and the other group will not.
The goal of the proposed research is to determine the extent to which Positive Affect Treatment (PAT), a novel treatment targeting reward mechanisms, can effectively target the psychological reward deficits that maintain anorexia nervosa (AN), and thus improve clinical symptoms.
This study focuses on representations of the interior of the body and interoceptive awareness in women with anorexia nervosa in comparison with women without eating disorders.
Anorexia Nervosa (AN) is a life-threatening eating disorder characterised by an intense fear of weight gain and disturbed body image, which motivates severe dietary restriction or other weight loss behaviours (e.g. purging). Treatment efficacy in adults with AN remains low: only a small percentage of individuals fully recover, and dropout rates are high. For adolescents with a relatively short term illness duration (under 3 years), family-based therapy has been associated with more favourable outcomes. However, for those adolescents with a longer illness duration (over 3 years), there are no specific treatments associated with positive long-term outcomes and these individuals are at risk of developing a severe and enduring form of the illness (SE-AN). In part, treatment can be problematic due to ambivalence, which is reflected in poor take-up of certain treatments (e.g. pharmacological treatments that lead to weight gain) and high drop-out rates. Repetitive transcranial magnetic stimulation (rTMS) has demonstrated efficacy for treatment of AN in adults and improving treatment adherence. However, this has yet to be investigated in adolescents with AN. This study will use a novel type of rTMS, theta burst stimulation (TBS), including intermittent TBS (iTBS) and continuous TBS (cTBS). TBS takes as little as a few minutes duration compared to the classical rTMS protocol which takes approximately 37.5 minutes. In addition, TBS has been found to produce longer after-effects of the induced plastic changes and has a lower stimulation intensity, which may therefore be more practical and potentially safer to administer in people with AN. Thus, the aim of this proof-of-concept trial is to obtain preliminary data on the safety and short-term (i.e. up to 24 hours) effects of a single session of iTBS and cTBS, compared to sham TBS, on reducing core symptoms of AN.
