Filter by:Up to 40% of Obsessive-Compulsive Disorder (OCD) patients do not respond to conventional treatments (medications or behavior therapy). For some of them, a neurosurgical treatment can be indicated. A previous study, employing bilateral double-shot ventral capsular/ventral striatal (VC/VS) Gamma capsulotomy (GVC) for OCD has shown that this radiosurgical technique is potentially efficacious and relatively safe. However, a few patients may develop complications associated to radionecrosis (eg., brain cysts) in a long-term follow-up, which are probably associated to lesion volumes. Another study, with the preliminary results of smaller VC/VS Gamma capsulotomy lesions has suggested that this procedure is safe and remains efficacious. Our aim is to investigate the efficacy and safety profiles of smaller, single-shot VC/VS Gamma capsulotomy for OCD. This study will support the development of a future double-blind, randomized clinical trial of single-shot VC/VS Gamma capsulotomy.
The purpose of this study is to determine whether pharmaco(epi)genetic study predict selective serotonin reuptake inhibitor (SSRI) responsiveness in advance before the appearance of the drug effect until 4 months(16 weeks), 6 months, and 1 year after administration of SSRIs.
This pilot study is proposed to determine the acceptability, feasibility and potential efficacy of ketamine, a medication that modulates glutamate in the brain, as a rapid treatment for obsessive-compulsive disorder (OCD) symptoms in adolescents and young adults with OCD. This study will recruit 6 youth (ages 14-22) who are diagnosed with clinically significant OCD and have failed at least one adequate trial of a Serotonin Reuptake Inhibitor (SRI) medication and a course of Cognitive-Behavioral Therapy (CBT) (unless unable to access or tolerate) for OCD in the past. Participants will receive a single infusion of intravenous ketamine and be assessed at regular intervals post-infusion for up to 14 days. At the end of the 14-day treatment phase, all participants will be offered three months of open treatment for OCD with medication and/or CBT.
The purpose of this study is to examine the brain functioning of children and adolescent with OCD before and after treatment with Exposure and Response Prevention (EXRP) therapy.
The purpose of this study is to determine whether tDCS is effective as an add-on treatment in SSRI-resistant patients with obsessive and compulsive disorder
Refractory obsessive-compulsive disorder (OCD) is a disabling condition. Deep brain stimulation (DBS) of the nucleus accumbens is the most tested therapeutic avenue for refractory OCD. However, large scale randomized controlled trials to evaluate the effectiveness of this approach are rare.
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.
This study will evaluate the effects of a computerized training program coupled with cognitive behavioral therapy (CBT) for OCD.
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 severely disabling psychiatric disorder with a worldwide lifetime prevalence of 2-3% (Islam et al., 2015).Despite the efficacy of pharmacological and behavioural treatment methods for most OCD patients, roughly one third do not demonstrate significant symptom improvement, even after aggressive treatment (Foa et al, 2007). The effectiveness of neurosurgical treatment methods (including ablative surgery) for those with severely disabling treatment resistant OCD is substantiated by clinical research (Greenberg, Rauch & Haber, 2010). The brain target of this procedure is usually the area between the anterior and middle third of the anterior limb of the internal capsule.
