NCT06647589
The purpose of the study is to examine the effects and feasibility of a specific form of psychotherapy, acceptance and commitment therapy (ACT), on religiously oriented obsessive and compulsive disorder (OCD).
NCT05967468
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.
NCT04480918
The purpose of this study is to examine the effects of interventional/procedural therapies for treatment-resistant depression (TRD) and Obsessive-Compulsive Disorder (OCD). These treatments include electroconvulsive therapy (ECT), transcranial magnetic stimulation (TMS), racemic ketamine infusion and intranasal esketamine insufflation. The investigators will obtain various indicators, or biomarkers, of a depressed individuals' state before, during, and/or after these treatments. Such biomarkers include neurobehavioral testing, neuroimaging, electroencephalography, cognitive testing, vocal recordings, epi/genetic testing, and autonomic nervous system measures (i.e. "fight-or-flight" response). The results obtained from this study may provide novel antidepressant treatment response biomarkers, with the future goal of targeting a given treatment to an individual patient ("personalized medicine").
NCT06131502
The goal of this clinical trial is to determine if ExAblate MR-guided Focused Ultrasound (MRgFUS) bilateral anterior capsulotomy can be used safely and effectively to relieve symptoms of moderate to severe obsessive compulsive disorder (OCD) in individuals who have not benefited from psychotherapy and medications. The main questions it aims to answer are: 1. Can ExAblate MRgFUS capsulotomy be safely delivered to individuals suffering from treatment-refractory OCD through an intact skull with a risk and side-effect profile that is comparable to other neurosurgical approaches for capsulotomy? 2. Will ExAblate MRgFUS capsulotomy result in improvement in clinical symptoms and quality of life metrics that are similar to those seen with other surgical approaches for capsulotomy? In the first stage of the study, participants with severe, treatment resistant OCD (n=10) will be recruited in two centers (Harvard and Stanford) and treated with best medical care (BMT) for 6 months. Thereafter, they will receive the ExAblate MRgFUS procedure and then another BMT for 12 months. In the second stage of the study, participants with moderate to severe OCD (n=56) will be recruited in a multi-center study and treated with BMT plus real or sham MRgFUS for 12 months. Thereafter, those who received sham MRgFUS and did not improve will receive real MRgFUS and then treated with BMT for another 12 months.
NCT07419009
This study tests out procedures to look at whether a type of brain stimulation called transcranial magnetic stimulation impacts flexible shifts in behavior in obsessive-compulsive disorder (OCD). This study examines whether study procedures are feasible and acceptable to people participating in the study, but does not determine whether this type of brain stimulation causes changes.
NCT05370911
This study aims to investigate the effects of repeated dosing of oral psilocybin on obsessive-compulsive disorder (OCD) symptomatology in a randomized, waitlist-controlled design with blinded independent ratings, and assess psychological mechanisms that may mediate psilocybin's therapeutic effects on OCD.
NCT07111988
The primary aim of the study is to examine the efficacy and safety of valbenazine in adults with moderate to severe obsessive-compulsive disorder (OCD).
NCT05623306
This is a multi-site, double-blinded, randomized, crossover study design for SEEG-guided 4-lead DBS for treatment-refractory OCD, followed by open label stimulation for an additional 6 months. The study will be conducted in 3 stages: Stage 1 will consist of SEEG brain mapping and optimization of stimulation parameters. Stage 2 will consist of DBS surgery and further optimization of stimulation parameters. Stage 3 will be randomized, crossover treatment, followed by open label treatment.
NCT07303946
This is a double blind pilot feasibility study, with a within subject crossover design of DBS of the anterior cingulate bundle(ACB) and the ventral anterior limb of the internal capsule(vALIC) in four patients with intractable OCD. Patients will be screened according to inclusion exclusion criteria listed above, approved by an independent Neuropsychiatric review board and informed consent obtained.
NCT06152913
A substantial part of children/adolescents with anxiety or obsessive-compulsive disorder (AD/OCD) do not profit substantially from first-choice treatment (i.e., cognitive behavioral therapy; CBT). For them, no evidence-based treatment is available. The aim of this project is to evaluate and optimize a newly-developed personalized, short, and intensive exposure-based intervention, 'HANDS-ON', for 'treatment non-responders'. Collaboration with children, parents and teachers, guided exposure in a child's natural environment, personalized treatment goals and meaning/motivation are central principles. Methods: A multiple baseline single-case experimental design is used (qualitative and quantitative). Participants are children/adolescents (10-18 years; N=12) with an AD/OCD diagnosis for whom standard CBT did not lead to sufficient improvement. Children and parents are asked to complete questionnaires before, during, and after the treatment. Children, parents, and school professionals will be asked to participate in qualitative interviews to evaluate their experiences with the HANDS-ON treatment program.
NCT07245134
The aim of this study is to evaluate the efficacy of virtual reality exposure therapy (VRET) as a treatment for obsessive-compulsive disorder (OCD). Participants are randomly assigned to one of the following interventions: a) exposure condition - the group with a standard CBT program enriched with exposure therapy in VR (VRET), b) control condition 1 - the group with a standard CBT program enriched with VR cognitive training aimed at cognitive flexibility or c) control condition 2 - standard CBT program without any additional VR intervention. The treatment effect will be evaluated using pre/post assessments, as well as monitoring adherence to exposure and response prevention assignments.
NCT07232823
The purpose aims to assess the efficacy of Brief Culturally Adapted Cognitive Behaviour Therapy (Ca-CBT) for the treatment of Obsessive Compulsive Disorder (OCD).
NCT04693351
The study's purpose its to evaluate the efficacy and safety of troriluzole as adjunctive therapy compared to placebo in subjects with Obsessive Compulsive Disorder (OCD)
NCT03459456
The investigators propose to synchronize automated measurements of behavior - head, body, and face dynamics, gaze, and vocal prosody - with simultaneous recordings of brain activity in clinically relevant contexts.
NCT04131829
The proposed randomized, double-blind research study will use functional magnetic resonance neuroimaging using state-of-the-art HCP acquisition protocols and analytic pipelines, to identify predictors and correlates of response to an accepted first-line pharmacological treatment for obsessive-compulsive disorder.
NCT05503017
Anxiety disorders are the most common form of psychopathology, and frequently begin in childhood, resulting in lifelong impairment. Increased brain activity after making mistakes, as reflected by the error-related negativity (ERN), is observed in people with anxiety disorders, even before disorder onset. The ERN is therefore of great interest as a potentially modifiable risk factor for anxiety. However, methodological issues can make the ERN difficult to measure. Increased brain activity in response to a balance disturbance, as reflected by the balance N1, resembles the ERN, but does not share its methodological issues. The investigators' preliminary data demonstrate that the balance N1 and the ERN are associated in amplitude in adults, suggesting they may depend on the same brain processes. The balance N1 has never been investigated in individuals with anxiety disorders, but it increases in amplitude within individuals under anxiety-inducing environmental contexts. Further, balance and anxiety are related in terms of brain anatomy, daily behavior, disorder presentation, and response to treatment. The present investigation will measure the ERN and the balance N1 in children (ages 9-12) with anxiety disorders, and further, how these brain activity measures change in response to a brief, 45-minute, computerized psychosocial intervention that was developed to reduce reactivity to errors, and has been shown to reduce the ERN. The investigators will recruit approximately 80 children with anxiety disorders, half of whom will be randomly assigned to the active intervention condition. The other half will be assigned to an active control condition, consisting of a different 45-minute computerized presentation. Participants assigned to the control condition can access the computerized intervention after participation in the study. The purpose of this investigation is to test the hypothesis that the balance N1 and the ERN will be reduced to a similar extent after the intervention, to demonstrate that these brain responses arise from shared brain processes. Transfer of the effect of the psycho-social intervention to the balance N1 would provide insight into prior work demonstrating that balance training can alleviate anxiety in young children, and well-documented benefits of psychotherapy to balance disorders. Collectively, these data may guide the development of multidisciplinary interventions for the prevention and treatment of anxiety disorders in children.
NCT03313622
Subjects that have a diagnosis of OCD will participate in a clinical interview and cognitive tasks, during which they will be exposed to their individual OC stressors or will be asked to make decisions related to information value and quantity while measuring neural activity and filming facial reactions. This will assist investigators to look for biomarkers of that change. This study offers a unique opportunity to develop biomarkers for key domains of OCD, and other neuropsychiatric disorders, that are grounded in brain neurocircuitry at the individual-patient level. Subjects will participate in a clinical interview (Day 1), and then tasks+EEG (Day 2). Day 1 will be 4 hours or less, and Day 2 will be 2.5 hours or less.
NCT02624596
The purpose of this study is to understand how ketamine brings about rapid improvement in Obsessive-Compulsive Disorder (OCD) symptoms.
NCT04723485
Obsessive-compulsive disorders are very damaging illnesses that can already manifest in childhood and adolescence. With an average prevalence from 1 - 3%, they are one of the most frequently diagnosed psychiatric illness in these age groups. With the further use of data, the treatment success can be significantly improved; causal variables/predictors can be recognized, understood and taken carefully into account. The anticipated incremental knowledge will ultimately help children and young people with obsessive-compulsive disorders to receive faster and more effective treatment.
NCT05224414
This study will conduct a randomized controlled trial of Cognitive Bias Modification for Interpretation (CBM-I) as an augmentation to treatment as usual for obsessive compulsive disorder (OCD). CBM-I is a digital intervention designed to directly manipulate interpretation bias through repeated practice on a training task, thereby inducing cognitive changes in a relatively automatic or implicit manner. Specifically, this study will examine the feasibility, acceptability, and clinical outcomes associated with CBM-I. Adults with obsessive compulsive disorder (OCD) will be recruited from a treatment program for this disorder and participants will be randomly assigned to either receive: 1) up to 12 sessions of CBM-I, or or up to 12 sessions of psychoeducation as a control condition.
