Filter by: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.
This preliminary study aims to examine the outcomes from a therapist guided, parent-led, CBT treatment for preadolescent children (aged 5 to 12 years old) with OCD. Specifically, this study aims to: 1. Examine outcomes for children who receive the therapist guided, parent-led, CBT treatment for preadolescent children with OCD. 2. Examine parents' experiences and views about the acceptability of the treatment approach.
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 research aims to evaluate the safety and efficacy of pBFS-guided High-dose rTMS therapy targeting preSMA for patients with treatment-resistant Obsessive-Compulsive Disorder.
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 goal of this clinical trial is to compare brief-intensive cognitive-behaviour therapy (CBT) with regular weekly CBT in people with anxiety-related disorders. The main question to answer is: will brief-intensive CBT improve functioning (work, family, social) more and faster than does regular weekly CBT? Participants will be asked to follow CBT treatment (20 sessions of 45 minutes in both conditions), and participate in 7 measurements with a total duration of 5 hours over 1 year. Researchers will compare: - Brief-intensive CBT: 16 sessions in 2 weeks + 4 follow-up sessions within 3 months - Regular CBT with 20 weekly sessions in 6 months
The purpose of this study is to understand how ketamine works in the brain to bring about a reduction in OCD symptoms.
