Filter by:Etude d'épidémiologie clinique multicentrique (IMM), naturalistique, comparant un échantillon clinique à un échantillon de témoins issus de la population générale. Cette recherche se fixe pour objectif principal de déterminer, sur un large échantillon de patients pris en charge pour anorexie mentale dans des unités de soins spécialisées, les caractéristiques de l'activité physique et la dépendance à l'exercice physique en comparaison avec des sujets issus de la population générale appariés pour l'âge et le sexe. Nous faisons l'hypothèse que les patients anorexiques mentaux sont plus actifs et plus dépendants à l'exercice physique que des sujets de la population générale de même âge et de même sexe.
Anorexia nervosa is a chronic mental health condition characterized by maladaptive food consumption (i.e., hypophagia) and distorted body image. There is substantial evidence of a phenotypic overlap between anorexia nervosa and anxiety disorders, as well as data suggesting the two share a common genetic pathway. Despite these findings, little research has examined fear conditioning among individuals with anorexia nervosa, and no research has examined whether individuals with anorexia nervosa have a propensity to overgeneralize conditioned fear stimuli, one of the more robust fear-conditioning markers of anxiety disorders. The current study assesses generalization of conditioned fear with fear-potentiated startle: the cross-species enhancement of the startle reflex when an organism is in a state of fear. Animal data, as well as an emerging literature in humans, tightly links fear-potentiated startle to the amygdala-based fear circuit. Thus, evidence of overgeneralized fear-potentiated startle in anorexia nervosa would link this eating disorder to hypersensitivity of the fear circuit and could inform the development of novel pharmacologic and psychological treatments for anorexia nervosa based on treatment models used in the anxiety disorders literature.
This study will use a data base of archived therapy sessions of family therapy for adolescent anorexia nervosa to determine the role of fidelity to treatment and outcome. In addition, it will develop a novel, more efficient way to train therapists in family therapy for adolescent anorexia nervosa and examine if it is feasible to conduct a trial comparing this novel training to standard, more intensive training.
Individuals with anorexia nervosa (AN) have long been observed to demonstrate symptoms in common with obsessive-compulsive disorder (OCD), in particular, an obsessive fear of normal weight leading to dangerous food restriction, as well as many compulsive rituals about food. Both AN and OCD are seriously handicapping and often resistant to conventional therapies. Given that the two conditions often co-occur and are associated with still unknown genetic risk factors, the aim of this project is to identify their shared and distinct patterns of brain activity. The investigators propose to use functional magnetic resonance imaging to compare brain response among adolescents with AN, OCD, and age-matched healthy individuals. Specifically, this study will investigate function of distinct brain circuits related to core aspects of these related disorders. The investigators use three tasks related to set shifting, global vs. local processing, and reward. Based on evidence of deficits in cognitive flexibility and ability to change behavior, the investigators hypothesize that adolescents with AN and with OCD will show hypoactivity of frontostriatal circuitry during cognitive tasks, and adolescents with AN will show hyperactivity in limbic regions in a reward task. This study is the first to directly compare brain activation patterns using functional neuroimaging in AN and OCD. The goal is to determine how abnormal brain activity relates to symptom formation, what accounts for shared characteristics amongst these disorders, and whether deficits in specific circuitry underlie their unique defining features. The study of shared and unique elements of functional brain circuitry reflects a new, emerging approach to the classification of psychiatric illness, one based on identifying unique combinations of biological risk factors that link related conditions. This approach is widely believed to be a critical step forward in developing more brain-relevant targeted strategies for preventative interventions.
The purpose of this study is to evaluate two training methods of IPT with mental health service providers in college counseling centers.
This study aims to investigate the feasibility of combining Cognitive Remediation Therapy (CRT) with Family Based Treatment (FBT) for future use in a randomized clinical trial to reduce the risk of adolescents developing persistent Anorexia Nervosa. Participants will be randomly assigned to one of two groups: one group will receive FBT and CRT, and the other group will receive FBT and art therapy.
This study investigates whether the implementation of a symptom diary for reporting and communicating chemotherapy-related symptoms improves symptom care and decreases symptom burden in adult patients treated with chemotherapy. The hypothesis is studied using a before-and-after design. First, symptom care and symptom burden will be observed in a sample of patients not being offered a symptom diary. Next, the symptom diary will be implemented at the participating hospital and symptom care and symptom burden will now be observed in a new sample of chemotherapy patients.
The aim of this study is to investigate whether Lactobacillus reuteri could have a beneficial role in treatment of children and adolescents with Anorexia nervosa who develop motility disorder due to the malnutrition regarding the normalization of the motility, as well as the possible role of probiotics on nutritional recovery, especially on bone health.
This is a pilot study investigating if cycloserine (DCS; a learning enhancement medication) augments exposure therapy for food anxiety in patients with anorexia and bulimia nervosa. The investigators expect that (a) exposure therapy will reduce anxiety (b) anxiety will be reduced more in the DCS relative to placebo condition (c) participants in the DCS condition will have a greater increase in Body Mass Index.
The purpose of this study is to demonstrate that bodily self-consciousness is subjectively and inter-subjectively constituted and that some dimensions of the bodily self-consciousness are impaired in Anorexia nervosa.
