Active clinical trials for "Obsessive-Compulsive Disorder"

The purpose of this study is to evaluate a behavioral treatment program for children and adolescents with OCD and their families. Exposure and Response Prevention (ERP) behavior therapy, in which the patient is gradually exposed to the object or situation that causes anxiety and is taught to refrain from responding in a compulsive manner, is combined with family counseling (Family Treatment Program). This treatment will be compared to Relaxation Training (RT). OCD is a long-term, often disabling disorder that can cause significant family disruption. ERP is a promising treatment for children with OCD, and it is thought that family participation (through the Family Treatment Program) may be a helpful addition. RT is a common treatment for anxiety. Patients are assigned randomly (like tossing a coin) to receive either the ERP/Family Treatment Program or RT. Both treatments will be delivered over 12 90-minute outpatient sessions to youngsters and their families. All participants (patients and family members) will be assessed for treatment response each month during treatment, after treatment is finished, and then at 2 follow-up visits over the following 6 months. A child/adolescent may be eligible for this study if he/she: Has obsessive-compulsive disorder (OCD), is medication-free, and is 8 to 17 years old.

Phase II of this study will examine the efficacy of the OC-Go application via a randomized controlled trial comparing standard exposure and response prevention (ERP) treatment for pediatric obsessive compulsive disorder (OCD) to exposure/response prevention (ERP) augmented with OC-Go. A cross-over design will be implemented for these 12 sessions of treatment, in which participants that were randomized to standard ERP will receive OC-Go augmented ERP for the second half of treatment, and vice versa. Efficacy will be investigated in a sample of 32 children with OCD.

Deep brain stimulation is an established treatment for movement disorders. New indications for deep brain stimulation are under investigation, among them severe and treatment-resistant obsessive-compulsive disorder. Here, the investigators investigate clinical outcomes, safety and mechanism of action of DBS in the BNST in a series of 11 participants with severe therapy-refractory OCD.

This is a randomized, double-blind, parallel-group, sham-controlled trial that aims to investigate the effectiveness of transcranial direct current stimulation (TDCS) on improving symptoms, quality of life, depression, and cognitive functions in 39 patients with obsessive-compulsive disorder (OCD) that are randomized in 3 experimental groups.

Psychological treatments are effective, but take a long time and can be burdensome. Therefore, avenues to optimize behavioral treatments are needed. Despite important advancements, neuroscience has had a limited effect on psychotherapy development. Therefore, one paradigm shift would be to develop neuroscience informed behavioral treatments. The investigators identified from the literature a problem that affects several mental disorders (emotion dysregulation) and a neural circuit that underlies this important concern. They found that this circuit is dysfunctional in those with psychopathology but can be changed with treatment. The goal is in one session to train this brain network to operate more efficiently and to test the short and long term effects of this intervention. The investigators plan to engage this brain network using a traditional psychotherapy strategy (cognitive restructuring) and to enhance learning using repetitive transcranial magnetic stimulation (rTMS), a neuromodulation technique through which magnetic stimulation enhances the electrical activity in brain areas close to the scalp. The study team proposed two studies to examine this novel approach, In one of the studies 83 participants were enrolled and 47 eligible participants were divided into 3 groups. All participants were trained in emotion regulation by first being asked to remember an event where they experienced a negative emotion and then being instructed either to think differently about the event, or to wait. Participants simultaneously underwent either active (left or right side of brain) or sham rTMS. In a second study 65 participants were enrolled, and 31 were assigned to either active left or sham rTMS guided using neuroimaging results. Across both studies, the investigators measured regulation in the lab and during a-week long naturalistic assessment. Participants in the second study returned for a follow up neuroimaging visit at the end of this week. Participants returned for a one moth follow up assessment and to rate feasibility, acceptability, and provide feedback. This proof of concept set of studies demonstrated feasibility and preliminary efficacy for this approach, which opens new frontiers for neuroscience informed treatment development.

The purpose of this study is to test the efficacy of 1-Hz repetitive transcranial magnetic stimulation (TMS) over the pre-supplementary motor area as a treatment for obsessive compulsive disorder. Additionally, this study aims to identify the mechanisms of action of TMS and potential biomarkers and predictors of treatment response.

The purpose of this research is to measure changes in brain activity with functional magnetic resonance imaging (fMRI) before and after cognitive-behavioral therapy for compulsive hoarding. Cognitive-behavioral therapy aims to help people change the thoughts and behaviors that maintain symptoms of hoarding. The investigators intend to enroll approximately 80 people with hoarding disorder and 40 people with no psychiatric disorder, between the ages of 20 and 60, for this study. The investigators believe that after treatment there will be changes in the brain activity of individuals with compulsive hoarding.

The purpose of this research study is to determine how well children with OCD can be helped using therapy that requires less clinic visits. The investigators are testing a Stepped-Care Cognitive Behavioral Therapy (SC-CBT) approach in which children receive a full course of parent-led, therapist-guided treatment for OCD. The goal is to see if therapy can be done in fewer visits to the clinic. Children receiving SC-CBT will start with Step One, which includes three therapy sessions over six weeks. Those who do not get better in Step One will "STEP UP" to Step Two which involves coming in to meet with a therapist for the remaining sessions. Youth receiving SC-CBT will be compared to youth receiving standard CBT in the clinic through this study. It is expected that Stepped Care will be an acceptable, cost-effect, and feasible treatment with outcomes similar to standard CBT.

Voluntary and involuntary attention processes are thought to play an important role in the development and maintenance of anxiety disorders including OCD. Individuals with OCD pay greater attention to threat information related to their illness and have difficulty shifting their attention from such triggers. Studies suggest that a change in attention bias may lead to a change in anxiety vulnerability. However, few studies have directly examined the causal role of attention bias in the maintenance of anxiety underlying OCD and whether modification of such biases may reduce pathological anxiety symptoms particularly in children. In this proposal, we aim to translate basic findings from research on cognitive biases in anxiety into a novel computerized intervention for child Obsessive Compulsive Disorder (OCD). The treatment is designed to target a basic cognitive vulnerability in OCD, namely the selective processing of threatening OCD-related information. 52 children with OCD will be randomly assigned to either a 12-session attention modification program (AMP) or an attention control condition (ACC). Clinical assessment of symptom severity along with a brief neurocognitive battery will be conducted before and after treatment. We hypothesize that children in the AMP group at end of treatment will show (1) decreased attention bias to OCD-related triggers using an independent measure of attention bias to assess change and (b) reduced OCD severity. This study is an initial step towards demonstrating the feasibility and efficacy of a novel computerized attention training program for OCD that ultimately may prove to be a highly transportable and accessible intervention for this childhood psychiatric disorder. Furthermore, the project will also examine neurocognitive performance before and after attention training to elucidate possible predictors and mechanisms of treatment response.

This study intends to explore the pathogenesis of obsessive-compulsive disorder(OCD) by using biological technologies such as genetics and imaging, and to evaluate the efficacy of group cognitive behavioural therapy in OCD among the Chinese people. We also prepare to explore the synergistic effect of the pharmacological treatment combined with group cognitive behavioural therapy in OCD, and to find the biological and psychological index which can predict curative effect. This research includes case control study and randomized controlled single-blind study. At baseline, we compare the dimensions of clinical symptoms, genetics and imaging between OCD patients and healthy controls. The OCD patients are randomly assigned into pharmacological treatment, psychological treatment or pharmacological combined with psychological treatment for a 12-week treatment. After a 12-week treatment, the OCD patients will be divided into valid and invalid groups according to the results of our randomized controlled study by researchers: to our valid group, patients will continue the current treatment, and to the invalid psychological or pharmacological treatment group, patients will have a 12-week combined treatment. From the baseline, we will have a 9-month follow up for both OCD patients and healthy controls.
