Filter by:People utilize two behavioral strategies, goal-directed and habitual, when engaging in value-based decision-making that involves rewarding or punishing outcomes. Accumulating evidence suggests an imbalance between habitual and goal-directed behavior in favor of habitual control in parallel with exaggerated tendency toward compulsive/harm avoidance behavior in OCD. In healthy subjects, an arbitration mechanism has been proposed recently that controls the balance between those two strategies of action selection. Arbitration regions regulate the goal-directed/habitual decision-making balance by selectively downregulating the activity of the habitual regions. This project aims to explore the neurobehavioral characteristics of arbitration mechanism and its relationship with behaviors and clinical phenotypes in OCD by applying computational cognitive neuroscience, clinical task-based functional magnetic resonance imaging (fMRI) and transcranial direct current stimulation (tDCS) method.
The aim of this study is to teach participants with a OCD diagnosis and treatment-resistance how to decrease the response from a brain region involved in the disease by using a technique called neurofeedback. While using this technique, the participants visualize their own brain response in a screen during a MRI exam. Participants will learn strategies to decrease brain responses. The neurofeedback technique is non-invasive, without known risks to participants. With this study, it is expect that the neurofeedback training over 2 weeks (2 sessions) will reduce the OCD symptoms when compared to a control intervention based on neurofeedback's placebo effects.
The primary objective is to examine the efficacy of implementing evidence based Exposure and Response Prevention (ERP) within group therapy versus individual therapy by monitoring reduction of Obsessive-Compulsive Disorder (OCD) symptomology.
DELPhI acquisition and analysis software, a QuantalX Neuroscience development, which is designed to measure, analyze, and display brain electrical activity of human electroencephalogram (EEG), to transcranial magnetic stimulation (TMS), will be used to evaluate different psychiatric conditions.
Title: Effect of Vitamin C upon Selective Serotonin Reuptake Inhibitors (SSRIs) - treated Obsessive Compulsive Disorder (OCD) patients. Purpose of the study: This study aims to examine the effect of vitamin C upon Selective Serotonin Reuptake Inhibitors (SSRIs) - treated Obsessive Compulsive Disorder patients. Method: It will be a prospective type of interventional study to to assess the effects of vitamin C along with SSRIs upon OCD patients. The study will be conducted in the Department of Pharmacology and Department of Psychiatry, BSMMU, from September 2017 to February 2019. A total of 90 OCD patients will be selected according to inclusion and exclusion criteria. The patients will be divided randomly into 2 groups: group A and group B. Group A will consist of 45 patients who will receive only SSRIs orally daily and group B would consist of 45 patients who will receive vitamin C, 500 mg BID orally daily along with SSRIs for 8 weeks. To see the effects of Vitamin C, Yale-Brown score of obsessive-compulsive disorders (Y-OCD) would be assessed by Yale-Brown Obsessive Compulsive Scale (Y-BOCS) at baseline (before vitamin C administration) and 8 weeks after intervention. Biochemical parameters of oxidative stress markers such as plasma malondialdehyde (MDA), plasma reduced glutathione (GSH) and plasma vitamin C level would also be performed at baseline (before vitamin C administration) and 8 weeks after intervention. Ethical consideration: The study will follow the principles of the Declaration of Helsinki and of the World Medical Assembly. Patients will be informed about the study in easy language and then informed consent will be taken. This study has no potential risk to the patients. Confidentiality will be strictly maintained.
Obsessive-compulsive disorder (OCD) is a severe mental illness characterized by repetitive behaviors that a person feels compelled to perform. It has been demonstrated that stimuli in the environment can trigger the compulsive urge, perpetuating the OCD cycle. The main goal of the current proposal, which is based on exciting pilot data, is to test a novel computerized training program to create an association between OCD-related stimuli, which typically trigger the compulsive urge, and the brain system responsible for stopping. The idea is that once this system is triggered, it will be easier for patients to stop the compulsive urge.
There is strong evidence that cognitive behavioral therapy (CBT) with exposure is the preferred treatment for youth with anxiety disorders, but outpatient services that provide this type of treatment are limited. Even for those who do have access to anxiety-specific treatment, a traditional outpatient model of treatment delivery may not be suitable. Among the numerous logistical barriers to treatment access and response is the inability to generalize treatment tools to settings outside of the office. Patient-centered (home-based or telehealth; patient-centered telehealth closed as of 5/1/21) treatment models that target symptoms in the context in which they occur could be more effective, efficient, and accessible for families. The present study aims to compare the efficacy, efficiency, and feasibility of patient centered home-based CBT and patient centered telehealth CBT with a traditional office-based model of care. The question proposed, including proposed outcomes, have been generated and developed by a group of hospital, payer, patient and family stakeholders who will also contribute to the iterative process of protocol revision. The investigators anticipate 379 anxious youth to be randomized to receive outpatient treatment using telehealth (patient-centered telehealth closed as of 5/1/21), home-based services, or treatment as usual using a traditional outpatient model. Results of this study are expected to provide evidence for the efficacy and efficiency of patient-centered treatment, as well as increase treatment access and family engagement in the treatment process.
The purpose of this study is to provide participants diagnosed with obsessive compulsive disorder (OCD) and completed one of the active study protocols at the Rodriguez Lab, with open/aftercare treatment.
The investigators propose to synchronize automated measurements of behavior - head, body, and face dynamics, gaze, and vocal prosody - with simultaneous recordings of brain activity in clinically relevant contexts.
The purpose of this study is to understand how cortical stimulation affects Obsessive-Compulsive Disorder (OCD) symptoms.
