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 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.
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.
Previous studies have highlighted the potential therapeutic benefits of receptive individual music therapy as an adjunct to standard care, in a variety of psychiatric ailments including mood and anxiety disorders. However, the role of music in the treatment of obsessive compulsive disorder have not been investigated to date. The present study therefore aimed to investigate the efficacy of music therapy as an adjunct to standard treatment, on obsessions in patients with treatment-naïve OCD. Moreover, given the fact that a significant proportion of patients with OCD have other comorbid mood or anxiety disorders, the question of whether therapeutic benefits of music could be expanded to also affect concurrent depressive and anxiety symptoms was explored.
This research study tests whether GLYX-13 - an experimental drug that acts on a brain receptor called NMDA - can decrease symptoms of OCD within hours. This is not a treatment study. Results from this study will allow doctors and researchers to better understand if you and others with OCD may respond to a class of medications that target the NMDA brain receptor.
The purpose of this clinical study is To verify the long term effectiveness and safety of a bilateral deep brain stimulation (DBS) produced by Beijing PINS Medical Co., Ltd. as a treatment option for patients with cognitive, behavioral, and functional disability of Obsessive-Compulsive Disorder.
This study is being done to learn whether administration of intranasal (inhaled through the nose) ketamine reduces symptoms of obsessive-compulsive disorder (OCD). Ketamine has been approved by the U.S. Food and Drug Administration (FDA) as an anesthetic agent (a medicine to reduce pain during surgery and other procedures) but ketamine has not been approved by the FDA as a treatment for OCD. The investigators believe that ketamine may be effective in reducing symptoms of OCD due to its ability to decrease the activity of a specific brain chemical called glutamate. Previous studies have shown that people with OCD can have abnormal levels of glutamate in their brains. This is the first time that intranasal ketamine is being studied in people with OCD. However, studies have been done in the past using intravenous (IV; through a needle into a vein in your arm) ketamine in people with OCD, and intranasal ketamine has been studied in people with other psychiatric conditions. This research study will compare ketamine to placebo. The placebo looks exactly like ketamine, but contains no ketamine. At some time during the study, the investigators will give you ketamine. At another time, the investigators will give you placebo. Placebos are used in research studies to see if the results are due to the study drug or due to other reasons.
