Filter by:This is a phase 2, randomized, controlled clinical trial to study the efficacy of pramipexol or risperidone in the treatment of refractory ODC patients. This study is a two-parallel-group clinical trial with duration of 28 weeks (recruitment phase, 4 weeks + treatment phase, 16 weeks + follow-up phase, 8 weeks. The primary endpoint of this study is the score in the Y-BOCS scale measured between baseline and EOT ( at week 16).
Psychiatric Comorbidity and quality of life in patients with Obsessive Compulsive Disorder(case control study )
Obsessive-compulsive disorder (OCD) is a psychiatric syndrome characterized by unwanted and repetitive thoughts and repeated ritualistic compulsions aimed to decrease the distress. Symptoms can cause severe distress and functional impairment. OCD affects 2-3% of the population and is ranked within the ten leading neuropsychiatric causes of disability. Dysfunction of the cortico-striatal-thalamo-cortical circuitry (CSTC) has been implicated in OCD, including altered brain activation and connectivity. A complex dysregulation of glutamatergic signaling within the cortico-striatal circuitry has been proposed in OCD. Data obtained by several studies are suggesting of a reduced glutamatergic concentrations in the anterior cingulate cortex, combined with overactivity of glutamatergic signaling in the striatum and orbitofrontal cortex. A growing number of RCTs have assessed the utility of different glutamate-modulating drugs as an augmentation or monotherapy in OCD, including refractory patients. However, there are relevant variations in between studies in terms of treatment-resistance, comorbidity, age and gender of the patients. At the present time four RCTs are available on the efficacy of memantine as an augmentation medication for refractory OCD patients. Investigators intend to conduce a double-blind, randomized, parallel group, placebo-controlled, monocentric trial to assess the efficacy and safety of memantine, a low-to-moderate affinity noncompetitive NMDAR antagonist that is currently approved for the treatment of Alzheimer disease, as an augmentative agent to a SSRI in treatment of patients affected by severe refractory OCD. Study design consists of four distinct periods (52 weeks) including memantine titration, neuropsychological assessment and follow-up.
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.
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 .
Cognitive Behavioral Therapy with fear provoking exposures is the most effective therapy for anxiety disorders. The investigators aim to enhance this therapy with the use of virtual reality exposures. The human subjects study will test the effects of using VR for exposures compared to traditional imaginal exposures on anxiety symptom improvement, functioning, child engagement in and response to exposures, completion of exposure homework between treatment sessions, and length of treatment in weeks and length of treatment among children with anxiety disorders and/or obsessive compulsive disorder. The funding award supports the development of the technology and the human subjects study. The subcontract to Mayo supports expert input to identify clinically relevant content for therapeutic videos on the VR system and the human subjects study to test the VR system.
Obsessive compulsive disorder (OCD) is one of the most disabling anxiety disorders occurring in about 2 out of a 100 adults. Untreated, OCD is a chronic and deteriorating condition, negatively impacting multiple areas of life with high personal and socioeconomic costs. In Denmark, anxiety disorders are estimated to be the most expensive of all psychiatric disorders and the most common reason for forced retirement. In many countries including DK, CBT is the recommended, first-line treatment for OCD. All individuals who seek treatment in the Danish Regions are offered CBT. However, reviews show that up to 50% of patients either do not respond to CBT or terminate treatment prematurely. Despite this large number of non-responders, no significant progress for OCD treatment has been made since initial efficacy trials. Alternatives to CBT are needed . Acceptance and Commitment therapy (ACT) is an innovative psychotherapy that can potentially help individuals with OCD who do not benefit from CBT. ACT targets the habitual thinking and behaviors that mark OCD by aiming to increase value-based behavior. OCD often co-occurs with depression and other anxiety disorders making treatment more difficult. ACT is a transdiagnostic treatment targeting symptoms that are common to anxiety and mood disorders. Preliminary findings indicate that ACT may be an effective treatment for OCD. However, these findings constitute a low level of evidence. Before ACT can be declared as an effective treatment for OCD, it needs to be demonstrated in randomize controlled trials, in which ACT is compared to legitimate, active treatments, such as CBT. This project will test the effectiveness of group-based ACT by comparing it to the first-line treatment, group-CBT in 180 participants referred for treatment in a specialized outpatient clinic at the Mental Health Services, Capital Region of Denmark. Furthermore, moderators and predictors of treatment response will be investigated.
Subjects that have a diagnosis of OCD will participate in a clinical interview and cognitive tasks, during which they will be exposed to their individual OC stressors or will be asked to make decisions related to information value and quantity while measuring neural activity and filming facial reactions. This will assist investigators to look for biomarkers of that change. This study offers a unique opportunity to develop biomarkers for key domains of OCD, and other neuropsychiatric disorders, that are grounded in brain neurocircuitry at the individual-patient level. Subjects will participate in a clinical interview (Day 1), and then tasks+EEG (Day 2). Day 1 will be 4 hours or less, and Day 2 will be 2.5 hours or less.
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?
The rationale for conducting the experiment including quantitative measures and a description of the method of recruitment: This study provides psycho-educational intervention aimed at raising awareness of post partum Obsessive-Compulsive disorder (OCD) , reducing the intensity of symptoms and increase of self referral to treatment. Various studies report that 1-11% of women after childbirth suffer from OCD. A part of this population suffered from the disorder prior to giving birth and for some this is a first outbreak. This is a psychological disorder characterized by obsessions and compulsions. The disorder can appear or worsen at any time , and is characterized by different content depending on the stage of life. Obsessional thoughts after birth often includes harming the baby which alarms the woman and the surrounding, and affects her ability to care for the baby and develop a beneficial relationship with him. Studies support a bio-psycho-social model of OCD .and that adjustment period and physical changes after childbirth can be create a psychological biological and environmental background, to the development or worsening of OCD in women who suffer from or are prone to the disorder. The present study deals with psycho-educational information which will be given to women after birth who were identified as susceptible to develop OCD. The information will be delivered in the maternity ward through written and recorded data , and sent through the system Qualtrics 4 weeks after birth. Psycho-education is an important first step in Cognitive Behavioral therapy for OCD and may lead to anxiety reduction and commitment to treatment. The information sent in the study is similar to the information provided at the beginning of standard Cognitive Behavioral Therapy.Women will be recruited from the maternity ward at Lis Maternity Hospital. In order to identify women at risk for OCD, All women in the maternity ward will be asked to fill a short questionnaire. Women found at risk or as suffering from OCD will be invited to participate in the study.
