Filter by:The purpose of this study is to identify abnormal brain signals associated with Obsessive Compulsive Disorder (OCD) and psychiatric symptoms and to investigate novel therapeutic stimulation sites. While treating OCD with standard deep brain stimulation (DBS) therapy, the investigators will also monitor the activity of the anterior cingulate and prefrontal cortex, a region known be involved with OCD, decision making, and emotion regulation, and the investigators will identify abnormal activity corresponding to the severity of a patient's OCD. The investigators will also investigate whether it is possible for stimulation delivered to these parts of the brain can improve OCD symptoms. These investigations have the potential to aid in the development of improved forms of DBS that can better target abnormal OCD brain signatures in the future. The investigators will implant a cortical electrode in addition to the ALIC DBS electrode and connect these to an implantable pulse generator that care store field potential data (Medtronic Percept). The decision whether the lead is placed in the prefrontal or cingulate cortex bilaterally will be based upon considerations of the surgical risks for a particular patient based upon their anatomy and the required surgical approach. At multiple time points post-implantation up to 2 years, in our clinic or patient's homes, cortical and subcortical signals will be recorded. Data will be collected while patient are resting or engaged in symptom provocation tasks, emotional/cognitive tasks while cortical stimulation is on and off. In addition to brain signal recordings, symptoms will be assessed using validated questionnaires and tasks to allow identification of neurophysiological correlates of OCD symptoms.
According to the literature the lateral part of the Orbito Frontal Cortex (lOFC) is a relevant bilateral target for repetitive Trans-cranial Magnetic Stimulation (rTMS) in Obsessive Compulsive Disorder (OCD). Both hemispheres are concerned in terms of target.
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.
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.
Obsessive-compulsive disorder (OCD) is a severe and debilitating anxiety disorder afflicting about 2% of the population. It is characterized by the presence of recurrent obsessions and/or compulsions that are time consuming and cause marked distress and/or impairment. Untreated, OCD runs a chronic and deteriorating course. According to the World Health Organization, OCD is among the top 10 leading causes of disability worldwide. Examination of non-medicinal treatments for OCD has focused on two distinct treatments: exposure and response prevention (ERP) and cognitive therapy (CT), often combined into an integrated cognitive-behavioural treatment (CBT). CBT is considered the first line psychological treatment for OCD, with estimates of response rates of between 70-80%. However, there are a significant number of treatment non-responders and the majority of responders are still left with impairing residual symptoms. One area of investigation that has shown potential benefit for general mood and anxiety disorders has been mindfulness-based interventions (MBIs), yet the potential benefits of MBIs in OCD has been largely unexamined, except for several small preliminary studies that show clinical promise. The purpose of this study is to examine the clinical benefits of a standardized MBI treatment for OCD in a large-scale, multi-site randomized controlled trial. The results of this study will directly determine whether Mindfulness can be considered an effective treatment for OCD. If this study can demonstrate that a short-term mindfulness intervention can significantly reduce the suffering associated with OCD, then the findings could easily be translated into routine clinical care in and out of hospital settings. Results of this study will also potentially add to our understanding of the mechanisms that drive OCD symptoms, improve our knowledge of psychological treatment mechanisms, and elucidate how biological factors influence psychological treatment outcomes.
In this multicenter study, the investigators want to find out if an addition of an diagnostic assessment and possibility of treatment with guided self-help CBT can increase the treatment effects of PCBH on patient functioning and symptoms, compared to standard PCBH which uses contextual assessment and brief interventions. In addition to this, the study will investigate the overall effect of PCBH on both patient and organisation level outcomes.
The purpose of the study is to assess the tolerability and efficacy of dextromethorphan in combination with fluoxetine for symptom relief in OCD and related disorders.
Obsessive-compulsive disorder (OCD) is a debilitating disorder characterized by unwanted intrusive thoughts and disrupting repetitive rituals. Epidemiological studies estimate the prevalence of impairing OCD to be between 0.5-3.0 % in pediatric populations. Although OCD in youth is associated with substantial distress and functional impairment, access to evidence-based psychosocial treatments is limited. This is largely due to the fact that few clinicians are trained in the delivery of evidence-based treatments, such as exposure-based cognitive-behavioral therapy (CBT). Therefore it is of great importance to develop treatment programs that utilize therapist resources in the most efficient way. Exposure-based CBT delivered in the context of a group, rather than individually, is one such option. However, there are currently no evidence-based group OCD treatment manuals for youth available to clinicians in Denmark. Therefore this project addresses an important clinical need. We evaluate a group-based CBT protocol for the treatment of youth with OCD, benchmarking treatment outcomes against data from a previous trial evaluating individual-based CBT and by comparing outcomes against a short waiting list period. Further, we will explore the impact of group-based CBT over a 36-month open follow-up interval on general functioning, relapse, recurrence rates, and the need for other treatments. Finally, a brief youth questionnaire assessing overall symptom severity relevant for the evaluation of outcomes in pediatric OCD will be translated and validated for future clinical and research use in Denmark. The project will include 72 adolescents with a primary diagnosis of OCD referred for assessment and treatment at the OCD Clinic at Department of Child and Adolescent Psychiatry, Aarhus University Hospital, Psychiatry, Denmark. For benchmarking of treatment outcomes, the project will compare the results from the group-based CBT with data from 45 Danish patients previously enrolled in the individual-based CBT of the Nordic Long Term OCD Treatment Study at the same clinic.
Obsessive-compulsive disorder (OCD) is a neuropsychiatric disorder characterized by recurrent distressing thoughts and substantial anxiety, accompanied by repetitive behaviors or mental rituals. Individuals with OCD often have diminished quality of life, and functional impairment . The disorder cause high personal, societal and economic costs . Current available treatments for OCD show moderate response rate and high rate of symptom relapse. The purpose of the current study is to explore new alternative options for the treatment of OCD that can widely and continuously benefit patients. Specifically, The aim of this study is to investigate the feasibility, safety and efficacy of psychotherapy assisted psilocybin for treatment of severe OCD. Previous research has shown safety of treatment and high efficacy in reduction of anxiety and depression symptoms. However, only one study has evaluated the use of psilocybin for OCD patients. The protocol includes 15 therapeutic sessions, of which 12 are one-hour sessions for psychological preparation and integration, and three are eight hours' experiential sessions under the influence of psilocybin. The research will include 15 participants diagnosed with severe OCD, with at least one treatment failure. Assessments will be based on comparing ratings of the main outcome measure (Y-BOCS), at baseline, at the middle and at end of treatment. Other assessments will include data on side effects- to evaluate safety, and possible spiritual variables underlying change in symptoms via standardized questionnaires.
The purpose of this research study is to test how a medication called nabilone (Cesamet) affects neurocognitive processes involved in obsessive-compulsive disorder (OCD), including threat response, processing of fear signals, and habitual behavior. OCD is a disabling illness that affects around 2% of the population and involves recurrent intrusive thoughts (obsessions) and repetitive behaviors (compulsions) that lead to distress and/or impaired functioning. Nabilone is a synthetic form of delta-9-tetrahydrocannabinol (THC, the primary psychoactive component of the cannabis plant). It acts on the brain's endocannabinoid system, which has been hypothesized to play a role in OCD symptoms. Nabilone is approved by the FDA for the treatment of chemotherapy-induced nausea and vomiting. It is not FDA-approved for treating OCD. In this study, 60 adults with OCD will receive a single dose of either nabilone or placebo. Participants will then complete a series of assessments including neuroimaging, psychophysiology (e.g., skin conductance recording), computerized behavioral tasks, and self-report measures. The information gained from this study could contribute to the development of new treatments for people with OCD and related disorders.
