Videoconferencing Adapted Physical Activity in Anorexia Nervosa: a Pilot Study
Anorexia NervosaExercise Therapy1 moreThe primary objectives of the APAREXIM'Pilot study are to evaluate the short- and medium-term effects of a live supervised Adapted Physical Activity (APA) program via videoconferencing on: Feasibility and acceptability of APA via videoconferencing by the patients. The primary symptoms of Anorexia Nervosa (AN). The secondary objectives are to evaluate the impact of this program on : Mental health Physical condition Sleep-wake cycle (sleep disturbance and physical hyperactivity) The patients will first undergo an inclusion visit (T0) at the University Hospital of Caen, then a first evaluation session (T1) at the COMETE laboratory in Caen (physical tests, questionnaires, sleep diary, actimetry). They will then be randomly divided into 2 groups: 15 patients who will follow an APA program supervised by videoconference for 8 weeks (AM-APA) at their home, in addition to the usual outpatient treatment, and 15 patients who will benefit only from the classic outpatient treatment (AM-T). All patients will undergo two additional evaluation sessions at one week post-program (T2) and at 3 months post-program (T3).
Contra-attitudinal Versus Mindfulness Treatment in Anorexia Nervosa Controlled Trial
Anorexia NervosaThis study propose to compare the effectiveness of two care programs, the CAT and cognitive therapy based on mindfulness (Mindfulness-Based Cognitive Therapy, MBCT) compared to the usual care ("Treated as usual", TAU) in AM and to show their benefit on dimensions specific to EDs such as body dissatisfaction and the internalization of the ideal of thinness, but also on eating symptoms and the anxious and depressive dimensions.
Impact of an Olfactory Sensory Therapeutic Group for Adolescent Patients With Restrictive Anorexia...
Anorexia NervosaAnorexia nervosa is a severe eating disorder of multifactorial origin and for which there is, to date, no specific, standardized and protocolized management for anorexic patients or data on the superiority of anorexia. type of psychotherapy. The literature reports altered olfactory capacities in anorexia nervosa and the effectiveness of sensory-mediated therapies in several mental disorders. This prospective, single-center, randomized and controlled study proposes the evaluation of the therapeutic impact of an olfactory sensory group carried out during the specialized care of patients aged 12 to 20 years, with anorexia. The main objective is to compare the clinical course of eating disorder, using the Eating Attitudes Test-40 (EAT-40) scale score performed at study inclusion and at 9 months at 9 months, of patients participating in an olfactory sensory therapeutic group compared to a body approach therapeutic group. The secondary objectives of this study are to compare between a treatment associated with an olfactory sensory therapeutic group and a body approach therapeutic group, the evolution of the Body Mass Index at 9 months, overall functioning, evolution of cognitive and sensory capacities, and evolution of the therapeutic alliance at 9 months
Dopamine Receptor Contributions to Prediction Error and Reversal Learning in Anorexia Nervosa
Anorexia NervosaAnorexia nervosa (AN) is an eating disorder associated with intense fear of weight gain, food refusal, and severe weight loss. AN has the highest mortality rate among the psychiatric disorders; however, little is known about biomarkers, and no medication has been approved for AN. Many individuals only partially recover, and treatment options, especially for the psychological components of the illness, are not very effective, highlighting the need for more effective treatments. Brain reward pathways have a direct impact on the drive to eat, and a variety of neuroimaging studies have suggested altered reward processing in AN. The neurotransmitter dopamine has a central role in the reward circuitry to drive food approach, and the dynamic interplay between dopamine receptor response and food restriction could have implications for the pathophysiology of AN. Dopamine-related brain function has been studied indirectly using functional magnetic resonance brain imaging (fMRI) and tasks that deliver reward stimuli unexpectedly, that elicit the so-called prediction error (PE) response. Research in AN showed repeatedly altered PE processing suggesting altered dopamine circuit function in the disorder. Dopamine and PE response have also been associated with altered reversal learning, which has important treatment implication for AN as reversal learning is impaired in the disorder and modulation of the dopamine system could improve treatment.
Pilot Study of Deep Brain Stimulation for Severe Anorexia Nervosa
Severe Enduring Anorexia NervosaAnorexia Nervosa (AN) has the highest mortality of any psychiatric disorder and a paucity of effective treatments. AN becomes intractable in around 20%, resulting in huge individual and healthcare costs. Exploration of underlying processes and novel treatment strategies is thus crucial. This is a pilot study of a novel translational approach to the investigation and treatment of severe AN. The aims are (1) to explore the safety, acceptability and feasibility of Deep Brain Stimulation (DBS) for AN (2) to map neural mechanisms underpinning aberrant reward and optimise DBS targets. The study will involve 10 consenting adults with full mental capacity, and the nain protocol will last 15 months. . There is then optional annual follow ups for up to 5 years .It incorporates an ethical substudy including assessment of capacity and informed consent. It combines complementary forms of cutting edge neuroimaging including fMRI and MEG (magnetoencephalography). These will be complimentary in helping identify the best strategy for treating severe AN using DBS. Individuals with severe intractable AN will be eligible to take part. The study will be conducted in Oxford, United Kingdom at the John Radcliffe and Warneford Hospitals. The individuals will have preoperative ethical, neuroimaging and psychological assessments, A DBS operation in month 2, DBS switch on in month 3 month postoperatively . DBS will be targeted to the Nucleus accumbens, followed by a 12 month post switch on follow-up period with monthly joint neurosurgical psychiatric and psychological assessments and postoperative MEG scans . The study will further our understanding of food reward processes in general and AN in particular indeed promises to provide important information which may revolutionize future treatments. The proposal builds upon a body of research investigating the role of aberrant reward processes in AN and exploits our complementary research experience in AN using experimental behavioural strategies, fMRI , MEG and DBS to establish a powerful translational research strategy.
Relapse Prevention and Changing Habits in Anorexia Nervosa
Anorexia NervosaThis study aims to optimize a treatment package for the relapse prevention treatment of AN. In the Preparation Phase, we examined accessibility and feasibility of the treatment package. In the current Optimization Phase, we will identify which components of treatment contribute to positive outcomes after acute hospitalization. We will carefully evaluate maintenance of remission, measured by rate of weight loss and end-of-trial status.
CGM in Patients With ED's
Anorexia Nervosa Restricting TypeAnorexia Nervosa3 moreTo determine the accuracy of continuous glucose monitoring (CGM) with point of care (POC) fingerstick glucose monitoring and venous blood glucose in patients with eating disorders, specifically anorexia nervosa, restricting subtype (AN-R); avoidant/restrictive food intake disorder (ARFID); and anorexia nervosa, binge/purge subtype (AN-BP).
Akershus University Hospital Retrospective Cohort Study of Family Based Treatment
Anorexia NervosaAtypical Anorexia NervosaThe goal of this observational study is to compare short and long-term effects of manualised Family Based Treatment for adolescent anorexia nervosa to those of non-manualised family therapy. The study will approach former patients who were treated before and after Family Based Therapy was adopted in an outpatient clinic, and extract data from electronic health records and public registries.
Incentive Processing and Learning in Anorexia Nervosa and Bulimia Nervosa
Anorexia NervosaBulimia NervosaThe purpose of this study is to investigate areas of the brain responsible for 'liking', 'wanting', and learning in adults with eating disorders using brain imaging techniques, computer tasks, a test meal, and self-report questionnaires and interviews. The investigators will study changes in brain activity using a procedure called functional magnetic resonance imaging (fMRI). This study will include 252 women with an eating disorder (63 AN-restricting type (AN-R), 63 AN-binge eating/purging type (AN-BP), 63 bulimia nervosa (BN)) and 63 healthy controls (HC) aged 18-39. Aim 1: To examine neural differences in 'liking' and 'wanting' in ED relative to HC. Aim 2: To examine differences in instrumental learning for reward and punishment in ED relative to HC. Aim 3: To examine how 'liking' and 'wanting' drive instrumental learning in ED and predict clinical symptoms at baseline and 1 year later. Exploratory Aim: To explore the associations of dopamine function, as measured by neuromelanin MRI (NM-MRI), with ED diagnosis and brain response to 'liking', 'wanting', and learning.
