Active clinical trials for "Obsessive-Compulsive Disorder"

This study will evaluate the safety and effectiveness of deep brain stimulation in treating people with severe and otherwise treatment-resistant obsessive-compulsive disorder.

The aim of the present study is to assess the efficacy of the module GGOC-AD (GG Obsessive-Compulsive Disorder - Adolescents) in reducing obsessive-compulsive disorder (OCD) related maladaptive beliefs and OCD symptoms in adolescents from 15 to 18 years old. Specifically, a randomized controlled trial with two conditions (experimental and control) will be carried out in a non-clinical adolescent population to assess pre-post-intervention changes. After 14 days of using GGOC-AD, it is expected, primarily, to find a decrease in OCD-related maladaptive beliefs and OCD symptoms. As secondary results, we do not expect changes in emotional symptomatology, but we do expect an increase in self-esteem. Additionally, these changes are expected to be found in a one-month follow-up.

This research study is for participants that have been diagnosed with intractable Obsessive -compulsive disorder (OCD). OCD is a persistent and oftentimes disabling disorder marked by unwanted and distressing thoughts (obsessions) and irresistible repetitive behaviors. OCD affects 2-3% of the US population, and is responsible for substantial functional impairment and increased risk of early death. The only established first-line treatments for OCD are cognitive-behavioral therapy (CBT) with exposure and response prevention and certain medications. About 30-40% of patients fail to respond and few experience complete symptom resolution. Up to 25% of patients have difficulty tolerating CBT and the risk of relapse after therapies remains large. For the most severe cases, neurosurgery (surgery in the brain), has long been the option of last resort. In this study the investigators want develop an adaptive Deep Brain Stimulation (aDBS) system to use in subjects with intractable (hard to control) OCD. Deep brain stimulation (DBS) remains investigational for OCD patients and is not considered standard therapy. DBS involves the surgical implantation of leads and electrodes into specific areas of the brain, which are thought to influence the disease. A pack implanted in the chest, called the neurotransmitter, keeps the electrical current coursing to the brain through a wire that connects the neurotransmitter and electrodes. It is believed DBS may restore balance to dysfunctional brain circuitry implicated in OCD. The goal of this study is to enhance current approaches to DBS targeting in the brain and to use a novel approach to find a better and more reliable system for OCD treatment. This current research protocol will focus on the completion of Phase II which will implant the RC+S system with ECoG paddles in 5 subjects.

Anxiety and obsessive-compulsive disorders are the most common mental health disorders in childhood and adolescence. A parenting intervention for youth with anxiety, called Supportive Parenting of Anxious Childhood Emotions ("SPACE"), has been recently developed to help target anxiety in children. In this intervention, therapists meet individually with parents to help them reduce anxiety behaviors in their children and support adaptive behaviors in their children. The purpose for the proposed study is to demonstrate the treatment efficacy of SPACE compared to a low-contact, therapist-supported bibliotherapy version of this intervention.

To investigate the benefits and harms, and the neural and neurocognitive mediators of treatment response, in family-based cognitive behavioural therapy versus family-based psychoeducation and relaxation training in children and adolescents with obsessive compulsive disorder. The aim is to conduct this investigation in an optimal trial design with the lowest possible risk of bias.

Repetitive transcranial magnetic stimulation (rTMS) has been shown in several previous clinical trials to be an effective treatment for obsessive-compulsive disorder (OCD). However, the neural working mechanisms of rTMS in OCD are unknown, and the optimal stimulation sites have not yet been established. Our study aims to compare the clinical and neurobiological effects of three different rTMS stimulation protocols in OCD patients. 8 weeks of rTMS therapy will be delivered in combination with cognitive behavioural therapy. Multimodal neuroimaging will be carried out before and after treatment in order to demonstrate the neurobiological effects of the therapy.

This study implements an anxiety-focused, parent-led, therapist-assisted cognitive behavioral teletherapy for parents of youth with ASD and anxiety.

The purpose of this study is to evaluate the efficacy of troriluzole as adjunctive therapy versus placebo in participants with obsessive compulsive disorder (OCD) who had an inadequate response to selective serotonin reuptake inhibitor (SSRI), clomipramine, venlafaxine, or desvenlafaxine treatment

The purpose of this study is to understand how ketamine brings about rapid improvement in Obsessive-Compulsive Disorder (OCD) symptoms.

Obsessive-compulsive disorder impacts 1-2 percent of the population. Unfortunately, about fifteen percent of patients fail to benefit from existing therapies. A small number of OCD patients, who have a disabling illness that does not improve after conventional treatments, have neurosurgery as a last resort. One procedure, capsulotomy, involves making pairs of lesions in an anatomically-defined part of the anterior limb of the internal capsule, a structure containing nerve fiber bundles connecting the thalamus, in the center of the brain, to the prefrontal cortex, the most anterior and outermost brain region. The investigators will examine how the therapeutic effects of capsulotomy relate to changes in the structure of these brain pathways with structural (diffusion tensor imaging, DTI) and functional (resting-state and task-based) connectivity metrics. The investigators will also utilize experimental cognitive tasks that are sensitive to the circuitry impacted by this procedure.
