Filter by:A factorial randomised controlled trial comparing internet-delivered combined cognitive bias modification intervention (iCBM-C) versus internet-delivered CBM-interpretation intervention (iCBM-I), internet-delivered CBM-attention intervention (iCBM-A) and wait-list control on obsessive-compulsive (OC) symptoms, OC-beliefs, OC-related interpretation and attention biases
In this study, the investigators aim to understand the role of transcranial direct current stimulation (tDCS) in modulating aberrant neurocognitive processes implicated in pediatric patients with obsessive compulsive disorder (OCD).
This study includes a sequenced clinical trial in order to assess the efficacy of several switching or augment strategies when initial treatment is ineffective,and to provide strong evidence for clinical practice and international guidelines for Obsessive-Compulsive Disorder treatments.
This study will evaluate the clinical effectiveness ofthe Immersive Virtual Reality alongside exprosure and response Prevention (ERP) Treatment in cognitive-Behavioral Therapy for Obsessive-compulsive Disorder, and the underlying neural mechanism by electroencephalography (EEG) and eye-tracking methodology .
This study aims to evaluate the feasibility and clinical outcome of the Exposure-based Cognitive-Behavioral Therapy (CBT) concurrent with Transcranial Direct Current Stimulation (tDCS) in treating obsessive-compulsive disorder (OCD) patients, and explores the potential neural mechanisms of treatment effect by magnetic resonance imaging (MRI) and electroencephalography (EEG).
The purpose of this study is to examine the effects of interventional/procedural therapies for treatment-resistant depression (TRD) and Obsessive-Compulsive Disorder (OCD). These treatments include electroconvulsive therapy (ECT), transcranial magnetic stimulation (TMS), racemic ketamine infusion and intranasal esketamine insufflation. The investigators will obtain various indicators, or biomarkers, of a depressed individuals' state before, during, and/or after these treatments. Such biomarkers include neurobehavioral testing, neuroimaging, electroencephalography, cognitive testing, vocal recordings, epi/genetic testing, and autonomic nervous system measures (i.e. "fight-or-flight" response). The results obtained from this study may provide novel antidepressant treatment response biomarkers, with the future goal of targeting a given treatment to an individual patient ("personalized medicine").
Obsessive Compulsive Disorder is a highly debilitating condition with a lifetime prevalence of 2%-3%, and a notable percentage of patients (40-60%) have a partial or no response to medications. The present gold standard for the treatment of OCD is medications (Selective serotonin reuptake inhibitors (SSRIs) / Clomipramine) + Exposure and Response Prevention (ERP). There is a significant need for alternative novel methods of treatment. One of the novel methods of treating OCD is using magnetic stimulation which has already been successfully used in the treatment of depression. Treating OCD is difficult with regular superficial repetitive Transcranial Magnetic Stimulation (rTMS) hence the need for coils that targets deeper structures. Thus, we are comparing the efficacy of the two different coils from two different manufacturers plus using ERP in combination with the different coils. 1. Deep Transcranial Magnetic Stimulation (DTMS) using BrainsWay H7 coil targets deeper structures such as medial prefrontal cortex. The H7 coil has already shown clear evidence in treating patients with OCD and has been approved by the FDA for clinical use. 2. Repetitive Transcranial Magnetic Stimulation (rTMS) using MagVenture Cool D-B coil could also target the medial prefrontal cortex. Hence it might also be equally effective as the BrainsWay H7 coil in treating patients with OCD.
This study used electroencephalogram (EEG) to predict the efficacy of repetitive transcranial magnetic stimulation (rTMS) in patients with obsessive-compulsive disorder.
This study is designed to find Electroencephalogram (EEG) biomarkers to predict transcranial direct current stimulation (tDCS) response in obsessive-compulsive disorder.
The aim of this project is to investigate: - The status of the central serotonin (5-hydroxytryptamine, 5-HT) system in compulsive behaviour and how it is affected by sub-chronic escitalopram administration - The mechanisms underlying how sub-chronic administration of escitalopram affects the central 5-HT system - How changes in cognitive performance, including the balance between habitual and goal-directed mechanisms, are affected in compulsive behaviour by boosting 5-HT function - How functional brain changes in cognitive function measured with magnetic resonance imaging relate to altered 5-HT function following escitalopram administration.
