Filter by:Neuromodulation techniques for the treatment of Obsessive-Compulsive Disorder (OCD) have expanded with the greater understanding of the brain circuits involved in this disorder. Transcranial direct current stimulation (tDCS) is a non-invasive neuromodulation technique that has been studied as an alternative for strategy for treatment-resistant OCD. The main study is a randomized, sham-controlled, double-blinded trial tDCS for OCD patients unresponsive to cognitive-behavioral therapy and/or selective serotonin reuptake inhibitors. Forty-four patients will be randomized to two groups: active or simulated intervention. The intervention consisted of delivering an electric current of 2mA to the cathode, positioned bilaterally in the cranial region corresponding to the supplementary motor cortex, and the anode positioned in the deltoid (neutral region), during 30-minutes, for four consecutive weeks. The primary outcome was the reduction in baseline YBOCS scores before and after of tDCS treatment. Secondary outcomes include measures of depressive and anxiety symptoms, genetic markers, motor cortical excitability and performance in neurocognitive tests.
Objectives 1. To test the effectiveness and acceptability of an augmented internet-supported transdiagnostic intervention in Romania. 2. To assess the cost-effectiveness of the Internet version of the transdiagnostic program as compared to a standard treatment/usual care.
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.
Cognitive Behavioral Therapy with fear provoking exposures is the most effective therapy for anxiety disorders. Investigators aim to enhance this therapy with the use of virtual reality exposures and to make therapy more available and accessible for patients with anxiety disorders. The societal benefit of increased access to therapy is that, if successful, it will increase the number of patients who receive appropriate treatment for an anxiety disorder.
The purpose of this study is to test the effects of non-invasive neuromodulation, transcranial magnetic stimulation on brain function in individuals with obsessive-compulsive disorder (OCD). This study is focused on the mechanism(s) by which brain stimulation might change the functioning of regions implicated in OCD, and thereby inform possible future therapeutic uses.
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 the current study is to investigate the effect of an acute administration of intranasal oxytocin, relative to placebo, on social cognitive impairments among individuals with body dysmorphic disorder and obsessive-compulsive disorder, compared to healthy controls.
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).
The purpose of this study is to compare two ways to stop taking an antidepressant medication and determine whether a faster or slower taper is better tolerated.
The aim of this study is to test the feasibility and acceptability of an internet-delivered cognitive behavior therapy (ICBT) intervention originally developed for neurotypical adolescents with obsessive compulsive disorder (OCD) in adolescents with OCD and autism spectrum disorder (ASD). This feasibility study will inform us how to adapt the original intervention to the specific needs of patients with ASD.
