Filter by:Obsessive Compulsive Disorder results in high social impact, affecting quality of life and tending to a chronic course. A considerable proportion of patients, up tp 60%, remain with symptoms even thought treatment is administrated. Therefore, new therapeutic interventions are highly necessary. In this context, repetitive transcranial magnetic stimulation has been used for several psychiatric conditions, including OCD treatment. Moreover, many approaches of neuromodulation seem to reach a better result when used a priming stimulation. In an attemp to optimize particularities of the thecnique applied, this study aims to assess if a priming stimulation with rTMS might impact in a better outcome when compared with rTMS without previous stimulation.
This is a single-center study about patients with severe resistant OCD. Main assumption is that performing 10 tDCS sessions with the anode positioned at the level of the right orbitofrontal cortex, and the cathode at the level of the supplementary motor area, associated with the provocation of symptoms before each session is effective in the reduction in obsessive-compulsive symptoms. After the inclusion visit, the treatment period is provided from D1 to D12 (one session per day from Monday to Friday, for two consecutive weeks, i.e. a total of ten sessions). Each tDCS session lasts 30 minutes at an intensity of 2 mA and is preceded by symptom provocation using a standardized procedure performed by trained personnel. The patients are then assessed on D42 and D102 (i.e. 1 month and 3 months after the end of the tDCS sessions).
This study will include two parts. The first part will include two patients in a non-blinded, non-randomized, open trial. They will undergo Deep Bran Stimulation (DBS) for OCD (targeting the amSTN), as clinically accepted and approved in Israel (by the MOH) and in other countries in Europe and the US. The second part will include eight patients. This part will be an interventional, randomized, double-blinded clinical trial (patient and psychiatrist; the neurosurgeon will activate stimulation during the randomization period and will not be blinded). All subjects will undergo standard pre-operative psychiatric and neurosurgical assessment. Around 4-6 weeks later subjects will undergo implantation of Medtronic implantable DBS system (bilateral brain leads model 3389, lead extenders and PERCEPT pulse generator). Intraoperative recordings will include single unit and local field potentials (LFP) for target identification and validation, as accepted for clinical use. In the second part of the study, blinded randomization for treatment or sham-control arms (1:1 ratio) will be held two weeks post-operation. Treatment and sham-control arms will continue for four months. At the end of four months treatment, the groups will be crossed-over for another four months. Thus, the sham-control group will start treatment (using pre-defined stimulation parameters) and the treatment group will start sham stimulation. Four months later (six and a half months from surgery), randomization will be over, and both arms will get open-label active treatment. Psychiatric assessments post-operation will take place after two weeks, one month, and then once every six weeks, in the first year for all study patients. Chronic recordings will take place using the clinically used and approved PERCEPT DBS pulse generator during the first year after surgery.
Anxiety and obsessive-compulsive disorders are among the most common in children. Although cognitive behavioral therapy (CBT) is an effective and evidence-based treatment for such disorders, access to CBT is often limited. Family-based and internet-delivered therapy is one method to increase access to care. The purpose of this project is to evaluate the comparative efficacy and treatment mechanisms of two lower-intensity but effective treatments for families of children with anxiety or obsessive compulsive disorder (OCD) via telehealth compared to an adapted Relaxation and Mentorship Training (RMT) intervention involving breathing exercises with a therapist.
This pilot study aims to compare the effect of transcranial direct current stimulation (tDCS) versus sham stimulation, delivered immediately prior to cognitive-behavioral therapy (CBT) for obsessive-compulsive disorder (OCD), on patient-reported outcomes. The investigator hypothesize that patients who receive active stimulation will experience greater improvement in OCD symptoms than those who receive sham stimulation.
The investigators aim to evaluate the safety and efficacy of pBFS-guided rTMS therapy targeting DLPFC for patients with treatment-resistant Obsessive-Compulsive Disorder.
It is known that 1 in 5 women experience psychological difficulties during their pregnancy or in the first year after giving birth. Unfortunately, in 75% of cases, these problems go undetected, resulting in the woman, her partner and the baby not receiving the proper care. For this reason, the Flemish government wants to screen all women in the perinatal period for their mental well-being using short questionnaires with the aim of referring them to appropriate care. Before they can recommend this screening to all women in the perinatal period, it is necessary to investigate the effectiveness of these short questionnaires, as well as the proposed stepped screening protocol. The investigators want to use this study to determine whether the questionnaires and the stepped screening protocol are sufficiently sensitive to detect mental health problems during this period. This means that they want to check whether the (future) moms who screen positive actually have problems and whether the (future) moms who screen negative effectively do not have psychological problems. In case of positive findings, teh investigators want to recommend that screening for psychological well-being should best be part of standard care in the future. Participants will be asked to answer some questions regarding depressive and anxiety symptoms using existing screening instruments (Whooley, GAD-2, EPDS and GAD-7). On the basis of an online application one can be assigned to the group that will be invited for a telephone interview by a study employee of the UZ Gent (psychologist or psyciatrist) to conduct a semi-structured interview within 2 weeks after completing these questions. The interviewer will ask questions about current psychological well-being and, where applicable, psychological problems in the past. The interviewer will not be aware of the responses to the questionnaires, so as not to be prejudiced. Being contacted for an interview does not necessarily mean that those women scored higher on the questionnaires, as they may also belong to the control group. In addition, a number of demographic data are requested (such as age, marital status, level of education, occupational category, how many pregnancies, number of other (living) children, (expected) delivery date, current forms of treatment (medications, psychotherapeutic interventions) and psychiatric history).
Impact of attention on obsessive through the THOUGHT-scale (Troublesome Human Obsessions and Untargeted General Habitual Thoughts Scale): a description of the content of thoughts according to the level of attention demanded by the environment in patients with obsessive disorder compulsive disorder (OCD) and patients without OCD" Validation of THOUGHTS.
The purpose of this study is to understand how ketamine works in the brain to bring about a reduction in OCD symptoms.
The goal of this clinical trial is to compare different forms of transcranial magnetic stimulation (TMS) for improving the outcomes of Exposure with Response Prevention (ERP) in youth and young adults with Obsessive-Compulsive Disorder (OCD). Researchers will compare three groups: ERP with one of two different active ("real") forms of TMS vs. ERP with sham ("fake") TMS. The main questions this study aims to answer are: 1) whether TMS normalizes functioning in brain circuits that contribute to compulsive behavior, and 2) whether TMS reduces compulsions during ERP. Participants will: - Complete clinical interviews, questionnaires, and computerized tasks - Complete two MRIs (brain scans) - Receive daily TMS followed by ERP for two weeks (10 sessions)
