Active clinical trials for "Obsessive-Compulsive Disorder"

The investigators are examining whether conditions of ambiguity during decision-making may prime intolerance of uncertainty beliefs (i.e., difficulties coping with ambiguity, unpredictability, and the future) and lead to impaired performance when individuals with obsessive-compulsive disorder (OCD) are making uncertain decisions compared to non-psychiatric controls.

The purpose of this research study is to evaluate whether Exposure and Response Prevention Therapy (ERP) can help adults with obsessive-compulsive disorder (OCD) in China following a training of professionals and ongoing consultation.

When comparing targeting precision between DBS in parkinsonian patients and OCD patients, an unexpected deviation from the planned targets was discovered in OCD patients (Nuttin et al., 2013). The objective of this trial is to investigate whether the use of a micro-electrode assisted technique improves targeting precision in DBS at the BNST.

Obsessive compulsive Disorder (OCD) is a frequent psychiatric disorder. Obsessions and compulsions are the two manifestations of this disease. Obsessions are recurrent anxious ideas, and compulsions repetitive behavior aiming to decrease this anxiety. OCD symptoms have been associated with cortical and sub-cortical dysfunctions and more precisely an hyperactivity of prefrontal cortex / basal ganglia loops. Functional neuro-imagery studies have shown a significant decrease of orbito-frontal cortex, anterior cingulate cortex, caudate nucleus and cerebellum activities after two OCD reference treatments : medication and Cognitive and Behavioral Therapy (CBT). Two groups of 20 patients are included in this study and follow a CBT for 15 sessions. They are randomised in two groups : one proposing a "reference CBT", the other associate CBT to a new psychopedagogic task developed by the investigators team. Clinical investigations and neuro-imagery data are collected at the main steps of therapies : before, during (half-therapy), at the end of therapies and 6 month later. Symptoms severity, patients and relatives quality of life are also assessed.

The study aims to pilot a new computerised cognitive behavioural therapy programme for a small case series of adults with obsessive-compulsive disorder. The investigators hypothesise that the findings will demonstrate improvements in symptomatology following the programme. The programme will have longer-term aims of being rolled out over a number of IAPT services within the NHS, reducing waiting lists and increasing therapist time.

The investigators are examining whether difficulties with cognitive control (i.e., the ability to stop one's thought process and shift attention) is a common problem across three types of repetitive, negative thinking: obsessions (as seen in obsessive compulsive disorder, OCD), worries (as seen in generalized anxiety disorder, GAD), and ruminations (as seen in major depressive disorder, MDD).

Deep brain stimulation for treatment resistant deep brain stimulation

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.

Internet-based psychotherapy for children and adolescents with obsessive-compulsive symptoms and an age of 7 to 17 years. Sessions are verified with teleconferencing with an psychotherapist, children and their parents. The psychotherapy is supported by an App and a wristband to obtain psychophysiological data.

Comparing schizophrenic patients with comorbid OCD and schizophrenic patients without OCD in response to Ziprasidone and in cognitive functioning as compared with OCD patients
