Filter by:The main goal of this trial is to demonstrate therapeutic efficacy of low dose ketamine in patients with OCD. We expect that ketamine will alleviate symptoms in the hours following application, but also - if effective - that the anti-OCD effects might last for several days after a single infusion.
Adult Psychiatry Clinic Medical University of Gdańsk (MUG) is a healthcare facility that provides ketamine treatment to adult patients suffering from mental health conditions. The Clinic especially treats individuals suffering from treatment-resistant disorders, like - mood disorders, anxiety disorders, obsessive-compulsive and related disorders, trauma and stressor-related disorders, somatic symptom and related disorders, and dissociative disorders. Herein, this naturalistic observation aims to look at the safety and tolerability of ketamine treatment to further develop the understanding of ketamine in the use of psychiatry.
This study, a case-control study, aims to investigate the function-metabolism coupling in decision-making confidence neural network of obsessive-compulsive disorder.
We explore objective indicators of the efficacy of natural psychotherapy in the treatment of disorders such as obsessive-compulsive disorder
Adolescents with Obsessive-compulsive Disorder (OCD) have obsessions, compulsions or both. OCD is a severe psychiatric disorder, affecting many aspects of the lives of adolescents. The first choice treatment for adolescents with OCD is Cognitive Behavioral Therapy (CBT), consisting of exposure with response prevention (ERP) and cognitive interventions. Considering the substantial group of non-responders to CBT, it is necessary to have more options for effective treatment of OCD. Inference Based Approach (IBA) is already an effective treatment for adults with OCD and is more effective on adults with OCD and poor cognitive insight. It is hypothesized that IBA could be an effective alternative for CBT in treating adolescents with OCD. This study will be a first step in examining the efficacy of IBA as treatment for adolescents with OCD. The aim of this study is to explore the potential efficacy of IBA as treatment for adolescents with OCD using a non-concurrent multiple baseline design with 8 participants who receive IBA for 20 sessions performed in one psychiatric centre in the Netherlands.
This study will test the feasibility, safety, and evidence for efficacy of psilocybin administration in participants with obsessive compulsive disorder (OCD). This will serve as a preliminary proof of concept study for future larger studies aimed to investigate the utility, cognitive mechanisms, and neural correlates of this intervention.
The goal of this clinical trial is to learn about the efficacy and cost-effectiveness of stepped-care Internet-based cognitive behavioral therapy (SC-ICBT) compared with Cognitive Behavioral Group Therapy (CBGT) and conventional medical treatment (treatment as usual, TAU) in adults with obsessive-compulsive disorder (OCD) in China. The main questions it aims to answer are: question 1: Whether the efficacy of SC-ICBT is noninferior to CBGT and TAU for OCD? question 2: Whether SC-ICBT is more cost-effective than CBGT and TAU for OCD? Participants will receive treatment (SC-ICBT or CBGT or TAU) for 6 weeks. Prior to the main study, we conduct a non-randomized pilot study to explore the efficacy and cost-effectiveness of SC-ICBT related to CBGT for adults with OCD in China.
The investigators want to learn more about how human beings learn not to fear and the impact of changing the fear network in the brain using transcranial Direct Current Stimulation (tDCS) in individuals with obsessive compulsive disorder (OCD). The investigators hope this study will help us understand how future treatments can help patients with OCD better control unwanted fear.
The aim of this study is to understand why patients with obsessive-compulsive disorder (OCD) fail in therapy. To understand the neural mechanisms involved in exposure therapy that support success and clinical improvement in order to improve therapy outcomes for OCD patients.
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.
