Filter by:The Frederick W. Thompson Anxiety Disorders Centre has experienced significant demand for services related to the treatment of Obsessive Compulsive Disorder (OCD), resulting in a significant wait time for service. Although Cognitive Behavior Therapy (CBT) is the most efficacious treatment intervention for OCD, there is a growing literature indicating the mindfulness based approaches can be beneficial in terms of managing acute mood and anxiety symptoms as well as reducing relapse risk following treatment.The goal of this study is to examine the potential benefits of using a consumer grade EEG-based biofeedback device that allows clients to engage in home based mindfulness meditation practices while they are waiting to receive clinical services. Specifically, this study will investigate the effects of meditation home practice on symptom alleviation, as related to specific OCD related cognitive processes.
This project seeks to identify causal neural mechanisms underlying unwanted, repetitive behaviors (compulsions). Using non-invasive brain stimulation coupled with practice in a computer task, we will modulate activity in a target brain region in two directions (up or down) and measure effects on compulsive behaviors and related measures. This work could ultimately lead to the ability to treat compulsions more effectively by targeting the regions of the brain that can help or hinder attempts to overcome compulsions.
The purpose of this study is to investigate if therapist-guided internet-delivered cognitive behavioral therapy (ICBT) in a stepped-care approach is an effective and cost-effective treatment in reducing OCD symptoms for children and adolescents compared to gold standard treatment (face-to-face CBT).
The study aims to improve patient-specific anatomical targeting of the Deep Brain Stimulation for the treatment of intractable OCD.
A small (N = 24) pilot study developed a new and brief cognitive-behavioural therapy (CBT) module for checking symptoms (CBT-C) in obsessive-compulsive disorder (OCD). CBT-C targets maladaptive beliefs about memory and results show that it is effective at significantly decreasing checking symptoms as compared to a waitlist control. The objectives of the current investigation are to further investigate CBT-C by (1) replicating the pilot results in a larger sample; (2) using an active control condition (treatment as usual) as the comparison condition (3) including a 6-month follow-up, and (4) determining whether the association between maladaptive beliefs about memory at pre-treatment assessment are related to degree of checking symptom reduction following CBT-C. The findings of the study will have theoretical significance in adding to our understanding of the maladaptive belief domains relevant to the development and maintenance of OCD and supporting the cognitive model of compulsive checking. The relevant clinical significance is the further development of an intervention that could improve outcomes in treatment of persons with OCD. The key practical outcome of the research would be to add a stepped care offering to patients with OCD.
This project investigates the use of 4 weeks of 24 mg/day ondansetron as compared to placebo on symptoms and brain functioning in patients with obsessive-compulsive disorder (OCD) and tic disorders (TD). Patients will be randomized to receive ondansetron or placebo for 4 weeks, with MRI scans and symptom assessments occurring at baseline (before any drug) and at the end of the 4 weeks. Patients will also be asked to come into the lab approximately 2 weeks into the trial for symptom assessments. The investigators hypothesize that after 4 weeks there will be greater reduction from baseline in sensory symptoms and the activation of the insula and sensorimotor cortex compared for ondansetron as compared to placebo.
Pragmatic trial of pharmacogenetic testing at the time of prescription for a selective serotonin reuptake inhibitor, tricyclic antidepressant or atypical antipsychotic. Does real time intervention improve patient outcomes?
A prospective, randomized, double-blinded study was conducted in 7 OCD patients during which 4 electrode contacts along a striatal axis were stimulated bilaterally. DBS electrode implantation followed a trajectory placing contact zero in nucleus accumbens (a common target for OCD treatment) with more proximal contacts placed in striatal segments defined using projections from prefrontal cortex subdivisions (ventromedial, orbitofrontal, dorsolateral) and anterior cingulate cortex.
The purpose of this study is to investigate the role of a mindfulness-based skills training program for parents of children with obsessive compulsive disorder (OCD). The investigators will explore if parents involved in this group experience any change in their levels of stress, feelings of being an effective parent and family relationships compared to a waiting list control period. The investigators will look at how the family manages OCD in their lives. In particular, if mindfulness skills training will help increase the parents ability to tolerate distress in their child secondary to OCD and as such reduce the family accommodation of OCD. As family accommodation is an important negative prognostic predictor for children with OCD, changes in OCD symptom severity and functional impact in these child will also be measured.
The aim of this study is to investigate the effectiveness of low-frequency (1Hz) rTMS (repetitive transcranial magnetic stimulation) over the pre-SMA (pre-supplementary motor area) in a sample of treatment-resistant OCD patients in a multicenter, controlled design.
