Filter by:The goal of this multiple baseline case series study is to test the effect of imagery rescripting (ImRs) in Obsessive Compulsive Disorder (OCD) and Body Dysmorphic Disorder (BDD). Primary objective :The course of schema or core beliefs and change in OCD and BDD. To investigate the effectiveness of imagery rescripting on factors presumed to underlie the disorder, according to schema theory, and on OCD and BDD symptoms. Secondary objective: The change in OCD and BDD symptoms (full questionnaire), schemata and modes, core emotions, mood, affect and obtrusiveness of intrusion. Other objectives are research into the working mechanisms of imagery rescripting by collecting qualitative data from patients and their practitioner in a qualitative interview. For this study, a multiple-baseline single-case experimental design (SCED) is used testing different outcome variables in 18 OCD patients and 18 BDD patients. After a variable baseline period of 3-8 weeks participants will start twice weekly with imagery rescripting for 12 sessions, followed by a 6 week follow up. Participants will rate schema- or core beliefs and OCD or BDD severity on a visual analogue scale. In addition participants will rate core emotions, affect and obtrusiveness of the intrusion. Secondary we will asses four times questionnaires about OCD of BDD symptoms, depression and schemas en modes. After treatment participants will be interviewed about their experiences.
The purpose of this trial is to evaluate the clinical efficacy, the cost-effectiveness and the 6-month durability of a therapist-guided, Internet-delivered cognitive-behavior therapy programme for children and adolescents with body dysmorphic disorder.
The goal of this observational study is to test the effects of a type of noninvasive brain stimulation called transcranial magnetic stimulation (TMS) on visual processing in adults with body dysmorphic disorder symptoms when combined with modifying visual attention. The main goals are to understand, in people with body dysmorphic disorder and people with subclinical body dysmorphic disorder: - The effects of intermittent and continuous TMS stimulation of parietal brain regions when done right before visual attention modulation on brain functional connections. - The effects of intermittent and continuous TMS stimulation of parietal brain regions when done right before visual attention modulation on global/holistic visual perception. Participants will receive one type of TMS (intermittent or continuous) followed immediately by an fMRI brain scan during which they will view images of their faces. On the second day, they will do the same, but receive either the intermittent or continuous TMS stimulation that they did not receive on the first day.
Body Dysmorphic Disorder (BDD) affects 2.3% of the population and is characterized by excessive concerns with imagined or minor defects in physical appearance. Retrospective outcome studies suggest patients affected by BDD don't typically benefit from surgical treatments while cognitive behaviour therapy (CBT) appears to provide symptom - reducing and distress - reducing benefits. Two different 8-week online CBT approaches to assisting individuals with this disorder are compared: one approach will integrate mindfulness meditation methods (in combination with CBT) and one approach will employ CBT methods without reference to mindfulness meditation.
With obesity on the rise, the number of metabolic procedures performed annually is also increasing. Bariatric surgery has a significant impact on metabolic disease but also results in significant weight loss. Approximately, 30-40% of excess weight is lost within the first year following surgery. One of the motivating factors for surgery for patients is body image dissatisfaction and the stigmatisation of living with obesity, which is linked to low esteem, anxiety and depression. However, studies have indicated that following bariatric surgery, patients continue to experience dissatisfaction with their new body and identity due to unmet expectations. The investigators aim is to start addressing body image issues prior to surgery and provide realistic expectations to patients. This study will be focusing on the feasibility and acceptability of 3D image reconstruction and virtual reality as a method of helping bariatric patients manage their expectations and improve body image satisfaction after surgery. Thereby, leading to better quality of life, improved psychological outcomes and prevention of disordered eating, anxiety and depression. The study will take place at St Mary's Hospital (London) and the West London NHS Trust Bariatric Clinic from March 2022 to September 2022 (7 months). The study aims to recruit 10 participants from the Tier 3 Bariatric Preoperative Group. Once the participant has provided written consent, a photograph of them will be taken using a handheld 3D scanner on a secure password protected device. The images will be processed to produce two reconstructed images, one with 15% less body weight and the second with 25% less body weight. The participants will be divided into groups of 5 and shown their reconstructed images using individual virtual reality headsets. The participants will only have access to their own images. This will be followed up with group peer discussion meetings and questionnaires.
The purpose of the study is to assess the tolerability and efficacy of dextromethorphan in combination with fluoxetine for symptom relief in OCD and related disorders.
A core symptom of body dysmorphic disorder (BDD) is perceptual distortions for appearance, which contributes to poor insight and delusionality, limits engagement in treatment, and puts individuals at risk for relapse. Results from this study will provide a comprehensive mechanistic model of brain, behavioral, and emotional contributors to abnormal perceptual processing, as well as how malleable it is with visual modulation techniques. This will lay the groundwork for next-step translational perceptual retraining approaches.
Anorexia nervosa is defined in DSM V as a quantitative and qualitative dietary restriction resulting in significant weight loss, intense fear of weight gain, altered weight and body shape perception (body dysmorphic disorder) and low self-esteem influenced by weight or body shape. Body dysmorphic disorder is the most difficult symptom to manage in anorexia nervosa and its persistence is a factor associated with relapse. Virtual reality exposure therapy has proven its effectiveness in the management of post-traumatic stress disorder in the military and is a widely used therapy. The effectiveness of this treatment using new technologies has not yet been studied for the treatment of body dysmorphic disorder in anorexia nervosa and is not used routinely. It could represent an interesting alternative to the physical approach in psychomotor therapy, traditionally offered to patients suffering from anorexia nervosa. It is important to evaluate the effectiveness of virtual reality exposure therapy in the management of body dysmorphic disorder in patients with anorexia nervosa by comparing these two care techniques.
This study investigates whether caloric vestibular stimulation can modulate a measure of insight in obsessive-compulsive spectrum disorders.
Anorexia nervosa is an eating disorder that begins frequently in adolescence between the ages of 13 and 19, which affects girls with a sex ratio of 10:1, and the prevalence for females varies from 0,3% to 0,9%. The current therapeutic arsenal has a limited success in the treatment of anorexia nervosa with a long-term mortality rate and a 12-month relapse rate of up to 10% and 40%, respectively. One of the most difficult symptoms to treat is a body dysmorphic disorder, also called dysmorphophobia, the persistence of this symptom is a major negative prognostic factor. The main treatment of dysmorphophobia is currently cognitive behavioral therapy (CBT). In most protocols, the technique of progressive exposure face to the mirror is used with low efficiency. Adapted physical activity has recently been proposed in the literature as a tool to improve body perception. Face of complex management of this major symptom that is dysmorphophobia, some offer to use virtual reality. It is in this context that the study proposes to study the contribution of virtual reality in the treatment of the body dysmorphic disorder of adolescent patients hospitalized for anorexia nervosa in the department of Child and Adolescent Psychiatry Salvator Hospital in Marseille. It will be compare the importance and the evolution of the dysmorphophobia between two groups of teenagers hospitalized in Space Arthur for anorexia nervosa: an experimental group receiving the treatment with the contribution of the virtual reality, and a control group receiving the reference treatment of dysmorphophobia used in our unit. It will be recruit 30 adolescent females with anorexia nervosa according to the diagnostic criteria of Diagnostic and Statistical Manual of Mental Disorders (DSM)-5. The subjects will be divided into 2 groups of 15 teenagers, according to a randomization list, a group with a classic protocol, a group with virtual reality. The subjects with virtual reality will have 5 exposure sessions where they will be able to model their body in view in 1st person and 3rd person, via an Oculus Rift. It will be compare the following parameters: the different scores related to dysmorphophobia according to different questionnaires, the self-evaluation of the Body Mass Index (BMI), in order to observe the evolution of the symptom, then the anxiety relative to the exposure of a BMI higher in order to work the fear of getting fat, the choice of the most pleasant BMI, to evaluate skinny body addiction. At the end of the study, we hope to highlight the effectiveness of virtual reality to fight against dysmorphophobia, in order to have a better estimate of its body aspect, and to impact the evolution towards the cure in anorexia nervosa in teenage girls. In addition to increasing our knowledge, this could allow to consider new strategies in the management of anorexia nervosa, and why not democratize more virtual reality with adolescents followed in child and adolescent psychiatry.
