Active clinical trials for "Depressive Disorder, Major"

To explore the effectiveness and safety of rTMS intervention with different targets in the left prefrontal cortex defined using the pBFS method, in adult patients with moderate and severe depressive disorder. Second, investigate the neural circuit that responds to the rTMS intervention using individualized brain image analysis, which may help to establish an effective target for the neuromodulation of patients with major depressive disorder.

The investigators aim to evaluate the safety and efficacy of pBFS-guided DMPFC target and high-dose rTMS therapy for the treatment of patients with treatment-resistant depression

The purpose of this randomized controlled trial is to evaluate whether the InMotion intervention, delivered via telehealth (using a HIPAA-compliant video platform or phone), which uses evidence-based behavioral and motivational counseling to increase daily physical activity, is an effective treatment for Major Depressive Disorder (MDD) for people who are at least one year out from sustaining a traumatic brain injury (TBI). The first aim is to compare the efficacy of the InMotion intervention to the waitlist control (WLC) condition on measures of depression severity and associated conditions in under-active adults with TBI and MDD. For the second aim the investigators plan to identify possible moderators of exercise treatment effects. The third aim will examine possible mediators of treatment outcome. In addition, the weekly dose of exercise, the extent to which exercise generates positive affect, and engagement in enjoyable or meaningful aspects of life will be explored.

This study aims to better adapt cognitive behavioral therapy for insomnia (CBTi) for people with comorbid depression by using objective sleep measures to tailor the behavioral interventions components of CBTi. Using ambulatory monitors, we also aim to investigate changes in brain activity and heart rate throughout the intervention. In this parallel-group randomized clinical trial, participants undergo one week of baseline ambulatory monitoring after which they are randomly assigned to one of two intervention arms: 1) digitally delivered CBTi (eCBTi) based on standard subjective sleep measures (sleep diary), or 2) eCBTi based on objective sleep measures (EEG headband). The intervention spans over 5-weeks, followed by a week of ambulatory monitoring and follow-up measures one week and one month after the end of the intervention. The study also includes a post-intervention interview to gather feedback on participant experiences. The overall protocol includes online questionnaires and structured clinical interviews assessing sleep, insomnia, and mental health, as well as treatment-related measures before, during, and after the intervention. It is anticipated that eCBTi using objective sleep measures will lead to better treatment acceptability, satisfaction, and effectiveness, including greater improvements in symptoms of insomnia and depression. It is also anticipated that sleep EEG and heart rate profiles will improve along the course of eCBTi.

This is a cross-sectional pilot study designed to establish hot and cold cognitive functions and underlying neurocircuitry in older adults with MDD. The investigators will study 60 participants aged 21-80 years old with MDD. All participants will undergo clinical and neurocognitive assessment, and Magnetoencephalography (MEG)/Magnetic resonance imaging (MRI) procedures at one time point. The investigators will also enroll 60 demographically matched comparable, never-depressed healthy participants (controls) to establish cognitive benchmarks. Healthy controls will complete clinical and neurocognitive measures at one time point. To attain a balanced sample of adults across the lifespan, the investigators will enroll participants such that each age epoch (e.g., 21-30, 31-40, etc.) has a total of ten subjects (n=10) in both the healthy control cohort and depressed cohort.

Double-Blind, Placebo-Controlled, Multicenter Study of Efficacy and Safety

The purpose of this study is to identify pharmacogenetic profiles associated with selective serotonin reuptake inhibitors (SSRI)-induced behavioral disinhibition in children with Major depressive disorder (MDD), anxiety disorders and/or obsessive-compulsive disorder (OCD) that could be used clinically to reduce the incidence of this adverse event and improve health outcomes.

This study is designed to examine SV2A density in MDD and PTSD as a correlate of synaptic density, and to determine whether ketamine administration will reverse the synaptic loss in vivo in human subjects. To our knowledge, this is the first human study to examine SV2A in vivo in MDD and PTSD and to use the first known drug (ketamine) that rapidly reverses synaptic loss to determine whether ketamine administration could restore some of the structural changes associated with depression and PTSD. After a screening process to determine eligibility, all subjects will participate in an MRI, and 2-3 PET scans with the administration of ketamine for one of the scans. Cognitive testing and a stress test may also be done on scan days.

This study aims to investigate changes in functional connectivity over a four week treatment course with intermittent theta burst stimulation (iTBS) in patients with major depressive disorder (MDD). To this end, seven weekly resting-state fMRI (rs-fMRI) scans at 7 tesla (7T) will precede, accompany and follow the iTBS treatment course. By obtaining several samples of the modulatory effects of iTBS on functional connectivity networks and simultaneous measurements of the depressive symptoms it will be possible to assess the time course of changes in connectivity across different networks, and to assess the overall relationship between the network modulation and the antidepressant effects of the treatment over time.

This intervention study aims to evaluate the effectivity of web-based cognitive therapy in reducing depression and anxiety in pregnant and postpartum women. Moreover, it aims to assess treatment feasibility and usability of the treatment in the same population. After an initial screening to determine the eligibility to participate, all participants fulfilling the inclusion criteria will receive their personal access login in order to start the intervention.
