Filter by:The purpose of this study is to evaluate the effectiveness of repetitive TMS (rTMS) delivered simultaneously with elements of cognitive behavioral therapy/exposure-response prevention (CBT/ERP) in adult subjects (greater or equal to 18 years old) with obsessive-compulsive disorder (OCD). This is an open label study that involves standard of care for OCD (CBT) and an investigational treatment modality (TMS). The investigators will compare the Yale-Brown Obsessive Compulsive Scale (YBOCS) scores before and after treatment to quantify clinical improvement. The side effects from TMS include, but are not limited to, headache, seizure, and general pain. CBT has minimal side effects other than mental discomfort during the exposure sessions. For safety concerns, pregnant women and subjects with seizure-related history will be excluded as well as other indicated conditions in the details protocol.
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
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.
Obsessive Compulsive Disorder (OCD) is a condition associated with recurrent intrusive distressing thoughts, images and urges compelling the person to perform neutralizing acts or thoughts to the extent of significantly interfering with their daily activities. The symptoms of OCD are associated with both subjective and objective signs of distress. Treatment for Obsessive Compulsive Disorder is often associated with significant subjective distress with high dropout rates and often only limited improvement. Attempts to reduce distress in anxiety often focus on re-establishing the sympathovagal balance by enhancing the vagal or parasympathetic tone and it has been suggested that this can reduce the mobilization behaviours of fight or flight response and improve emotion regulation. This study will investigate the effect of a procedure potentially reducing distress and improving outcome of treatment in inpatients admitted for treatment for OCD to the Anxiety Disorders Residential Unit. The procedure will be based on increasing vagal tone by application of cold face mask on 3 consecutive days in addition to the standard Exposure and Response Prevention therapy (ERP).
Anxiety disorders affect 40 to 50% of children with autism spectrum disorders (ASD), contributing to substantial distress and impairment. The goal of this study is to examine the effectiveness of a personalized type of psychotherapy against standard-care psychotherapy for addressing anxiety in youth with ASD.
For this human research, 17 treatment-refractory OCD patients who already received DBS implants for treatment refractory OCD between June 1998 and October 2007 will be included. New patients that complete the protocol on "refining the target for DBS in OCD" will be included in this follow-up study as well. They will be psychiatrically evaluated on regular bases: at least twice yearly in the years two to five after surgery, at least once a year for the years thereafter. The duration of this protocol is indefinite, but spans at least 10 years. The main aim of this study is to investigate the long-term effect of DBS in OCD patients.
Pediatric obsessive compulsive disorder (OCD) is a relatively common and often severe condition that can become chronic if untreated. One of the most effective treatments for OCD is a type of cognitive behavioral therapy called exposure and response prevention (ERP). ERP involves presenting a patient with feared objects or situations (the content of their obsessional fears) in a gradual manner while helping them use coping techniques to refrain from engaging in rituals (compulsions). Despite several studies suggesting that ERP is an effective treatment for pediatric OCD, many youngsters fail to respond to this treatment, or respond only partially. An exciting recent finding from animal research is the ability of an established antibiotic (traditionally used to treat Tuberculosis), D-cycloserine (trade name: Seromycin) to enhance certain types of learning among rats. The type of learning that is enhanced is called extinction learning and many researchers believe that extinction learning is the equivalent process to what occurs during ERP; it is the process whereby repeated exposure to the object of fear without any bad outcome causes the object to cease being associated with danger. Several clinical trials using ERP and other forms of exposure treatment for adults with anxiety disorders reproduced this finding from the animal literature; pairing DCS with exposure treatment (comparable to extinction learning) resulted in greater fear reduction than when no DCS was administered. The effects of DCS on exposure treatment for anxiety disorders among children has been tested only preliminarily in one study of children with OCD and results were unclear with children who received DCS augmentation showing non-significant but increased levels of improvement as compared with children who did not receive DCS augmentation. In this study, 26 youngsters ages 7-17 with a primary diagnosis of OCD will be recruited and assigned at random to one of the two treatment conditions. Youth in the DCS condition of the study will receive 50 mg DCS 1 hr prior to each treatment session, while youth in the placebo condition receive an identical placebo capsule 1 hr prior to each treatment augmentation session. All participants will receive 180 minutes of CBT for OCD 4 days per week for 2 weeks during their study participation (as included in IOP already). All families complete a thorough evaluation no more than 5 days prior to receiving DCS on their 9th treatment visit in IOP (third week), and at mid-treatment augmentation (after the 12th IOP treatment session), post-treatment augmentation (after the 16th IOP treatment session), and 3-month follow-up (12 weeks after the 16th IOP treatment session). The primary aim of this study is to obtain preliminary data comparing the effects of the acute administration of DCS versus placebo on symptom response to exposure treatment for pediatric OCD. Results from this study will help to inform and refine future studies, and eventually, impact treatments for pediatric OCD.
