Filter by:The investigators will examine compulsivity in those who have recovered from anorexia nervosa, using a multi-modal MRI study. The neural activation of key fronto-striatal areas will be explored using a task which examines set-shifting and reversal-learning, two key components of compulsivity. Additionally, the functional networks displayed during resting-state MRI will be examined between groups, as will the neurochemicals present (using Magnetic Resonance spectroscopy).
This project seeks to identify causal neural mechanisms underlying unwanted, repetitive behaviors (compulsions). Using non-invasive brain stimulation coupled with practice in a computer task, we will modulate activity in a target brain region in two directions (up or down) and measure effects on compulsive behaviors and related measures. This work could ultimately lead to the ability to treat compulsions more effectively by targeting the regions of the brain that can help or hinder attempts to overcome compulsions.
The rationale for conducting the experiment including quantitative measures and a description of the method of recruitment: This study provides psycho-educational intervention aimed at raising awareness of post partum Obsessive-Compulsive disorder (OCD) , reducing the intensity of symptoms and increase of self referral to treatment. Various studies report that 1-11% of women after childbirth suffer from OCD. A part of this population suffered from the disorder prior to giving birth and for some this is a first outbreak. This is a psychological disorder characterized by obsessions and compulsions. The disorder can appear or worsen at any time , and is characterized by different content depending on the stage of life. Obsessional thoughts after birth often includes harming the baby which alarms the woman and the surrounding, and affects her ability to care for the baby and develop a beneficial relationship with him. Studies support a bio-psycho-social model of OCD .and that adjustment period and physical changes after childbirth can be create a psychological biological and environmental background, to the development or worsening of OCD in women who suffer from or are prone to the disorder. The present study deals with psycho-educational information which will be given to women after birth who were identified as susceptible to develop OCD. The information will be delivered in the maternity ward through written and recorded data , and sent through the system Qualtrics 4 weeks after birth. Psycho-education is an important first step in Cognitive Behavioral therapy for OCD and may lead to anxiety reduction and commitment to treatment. The information sent in the study is similar to the information provided at the beginning of standard Cognitive Behavioral Therapy.Women will be recruited from the maternity ward at Lis Maternity Hospital. In order to identify women at risk for OCD, All women in the maternity ward will be asked to fill a short questionnaire. Women found at risk or as suffering from OCD will be invited to participate in the study.
Individuals with high functioning autism spectrum disorder (ASD) frequently experience obsessions and/or compulsions that are similar to those specified in Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5) criteria for obsessive compulsive disorder (OCD). However, little research exists on effective interventions for OCD symptoms (referred to as OCBs) in ASD. In a randomized controlled trial, a manualized functional behavior-based cognitive-behavior therapy (Fb-CBT) consisting of traditional CBT components (psychoeducation and mapping, cognitive-behavioral skills training, exposure, and response prevention) as well as function-based behavioral assessment will be evaluated. Participants will be assigned randomly to Fb-CBT or treatment as usual (TAU). Primary and secondary outcome measures will be used to evaluate the efficacy of the treatment, and will be administered at pre and post-intervention as well as six month follow-up.
Following the realisation that many aspects of the way we live our life, such as our diet, activity levels, and amount of screen time, can have a potent impact on mental health and brain functioning 'lifestyle' based interventions have become topical in medical research. In particular, much scientific attention has been devoted to the impact of physical exercise and various stress reduction techniques on mood disorders. We aim to extend this work and investigate their impact on compulsivity. We will do this by conducting a pilot proof-of-principal intervention study. The study will compare the impact of eight-weeks of: 1. regular physical exercise + stress management activity A, 2. regular physical exercise + stress management activity B, 3. lifestyle as usual. The participant cohort will be adults who endorse mild-moderate behavioural compulsivity on one of the following domains: - drinking alcohol - gambling - eating - washing or cleaning - checking - ordering or arranging objects
Internet-based psychotherapy for children and adolescents with obsessive-compulsive symptoms and an age of 7 to 17 years. Sessions are verified with teleconferencing with an psychotherapist, children and their parents. The psychotherapy is supported by an App and a wristband to obtain psychophysiological data.
Mental-health conditions affect million people worldwide. The economic burden of mental illness is enormous and the economic health of both developing and developed nations will depend on controlling the staggering growth in costs from mental disorders. Obsessive-compulsive disorder (OCD) is a relatively common and frequent form of anxiety that affects approximately 2-3% of the population. OCD is characterized by anxiety, obsessions (persistent intrusive thoughts and images with highly distressing contents) and compulsions (repetitive activity), and severely impairs the lives of those affected. Despite their interest as effective and affordable care and rehabilitation, cognitive therapeutic profits too little from the increasing accumulation of knowledge in neuroscience, and neuroscientists pay too little attention to the challenges faced by clinical psychologists and psychiatrists. To reduce this cultural gap, two teams specialized in the study and multimodal imaging of healthy participants and clinical patients with mental health disorders, the UMR-S INSERM-EPHE-UNICAEN U1077 unit led by Francis Eustache, and ISTS team (UMR-S 6301 CNRS-CEA-UCBN) led by Sonia Dollfus, will joint their efforts to develop an integrated approach of the neural mechanisms at stake from basic neuroscience using state-of-art neuroimaging techniques, to novel and ground breaking psychological intervention. Both teams evolve at the brain imaging Cyceron center in Caen in connection with the Mental Health and Addictology Center, offering unique opportunities for such translational research. This project will capitalize on recent evidence showing that healthy participants can prevent unwanted images from entering consciousness using inhibitory control and memory suppression techniques, disrupting traces of the memories in sensory areas of the brain, and weakening their vividness and later reentrance. OCD is characterized by aberrant and excessive visual intrusions, usually extremely vivid, detailed, and unpleasant. These distressing images are particularly uncontrollable and may frequently initiate compulsive rituals. In a first phase of this proposal will use functional magnetic resonance imaging (fMRI) to develop a neurobiological model of the cognitive computations achieved by inhibition network to suppress memory. To achieve this goal we will develop an attentional model of healthy memory inhibition functioning, simulating the deployment of attentional resources and the different mental processes at stake during suppression. Using sophisticated analyzing tools of fMRI data, we will use this model to decode and infer the representational content of the brain inhibition network, and further refine the connectivity pathways which underlie such control. The lack of a strong neurobiological model prevents the development of therapies which would increase functionality of this network and optimize intervention aiming to disrupt mental intrusions and obsessions. In a second phase, we will assess whether memory suppression may be transferred and trained in OCD patients using images depicting their own obsessions, as a promising avenue to reduce their symptoms on the long run. In addition, fMRI and other brain structural acquisitions will be collected before and after cognitive training to memory suppression, offering a unique opportunity to observe the online dysfunction of intrusion control in OCD patients and to identify neurobiological markers predictive of training outcome and network reconfiguration with training. A fundamental goal of motivated forgetting involves not only to exclude unwelcome content from consciousness but also to reduce their later emotional impact by doing so. In parallel of these two main phases, we will thus also measure physiological markers of autonomic nervous system activity changes in response to suppressed images to better identify the consequences of memory suppression on emotional states, anxiety, and mental health in general.
The investigators will examine whether compulsivity in those who score above-average (but below clinical cut-off) on an eating disorder questionnaire can be altered by 9 days of N-acetyl cysteine (NAC). N-acetyl cysteine has been shown to be of some benefit in individuals with other compulsive disorders, such as trichotillomania and addiction, so this research investigates whether a short period of time taking N-acetyl cysteine changes compulsivity, measured using cognitive tasks and questionnaires.
From 1999 onwards, Deep Brain Stimulation [DBS] has been proposed as an alternative to capsulotomy in refractory cases of Obsessive-Compulsive Disorder [OCD]. More recently, several studies with DBS in patients with major depression have been initiated. In Belgium, there is currently a reimbursement for devices for DBS for OCD, but not for rechargeable neurostimulators, in these OCD patients. Although rechargeable neurostimulators are widely used in spinal cord stimulation for pain and DBS for movement disorders, they have not yet been used in DBS for psychiatric disorders population. Several possible problems might arise with the use of rechargeable neurostimulators in this highly specific population. In this prospective study with a before-after design, we would like to determine if the use of rechargeable neurostimulators is effective, applicable and safe and capable of diminishing the need for neurostimulator replacement procedures.
The purpose of this study is to evaluate the feasibility and effectiveness of Internet-delivered Cognitive Behavior Therapy (ICBT) for children (7-11 years) with Obsessive-Compulsive Disorder (OCD).
