The study's goal will be achieved through 3 specific aims: Demonstrate device capability to selectively and predictably engage distinct brain networks Delineate depression-relevant networks and demonstrate behavioral changes with network-targeted stimulation Demonstrate that chronic DBS using steered, individualized targeting is feasible and safe for reducing depressive symptoms
Novel Neural Circuit Biomarkers of Major Depression Response to CCBT
DepressionMajor Depressive Disorder3 moreThe purpose of the study is to learn more about computer-assisted cognitive behavioral therapy or "CCBT" and to examine connections in the brains of patients with depression. CCBT is approved by the FDA as a form of treatment for depression. It is done partly on the computer and partly with a therapist. This study will enroll participants with depression and participants without depression. The investigators will recruit a total of 100 participants: 80 with Major Depressive Disorder (MDD) and 50 matched comparison participants. Healthy control subjects will participate for approximately 8 weeks. All MDD participants will receive CCBT. Half of the MDD participants will all receive computer-augmented skills training with the Good Days Ahead (GDA) protocol immediately (Early CCBT). Early CCBT subjects will participate for approximately 8 weeks. The other half of the MDD participants initially will be randomized to a waitlist of up to 4 weeks and subsequently will receive CCBT treatment (Late CCBT). Late CCBT subjects will participate for approximately 12 weeks. All participants are asked to complete a screening, which includes a series of clinical interviews and self-report questionnaires about the individual's thoughts, moods, and behaviors. All participants are asked to wear an actigraph, which is a watch-like device that measures activity levels. Additionally, participants are asked to completed short questions and have their activity levels monitored through phone app(s). All participants (Healthy Control and MDD participants) will receive functional magnetic resonance imaging (fMRI) scanning at baseline. Early CCBT participants will receive fMRI scanning after 8 weeks of CCBT, and Late CCBT participants will receive fMRI scanning at the conclusion of the waitlist and after the 8-week course of CCBT. Brain activity will be compared between MDD and controls at baseline and between Early CCBT vs Late CCBT. The 2nd and 3rd brain scans of Late CCBT participants at the end of the waitlist and 8-week course of CCBT, respectively, will allow within-subject comparison of CCBT vs Waitlist treatment effects. This clinical trial has two IRB protocol numbers: 826910 and 832295. The data collected through both protocol numbers will be analyzed together to accomplish the target of 100 subjects for this clinical trial.
Home-based Non-invasive Brain Stimulation for Treatment-resistant Depression Feasibility, Efficacy...
Major Depressive DisorderDepression has a yearly prevalence superior to 5%, but a 30% of patients cannot benefit of pharmacological treatment, resulting resistant to it. Transcranial direct current stimulation, due to its reduced invasiveness and easy administration showed to be a useful technique to treat these cases, and it is now broadly used in clinical practice. Moreover, thanks to technological advances, this treatment could be self-administered at home, reducing costs and improving scalability. The aim of this study is to confirm the efficacy, safety and feasibility of a home-based intervention for treatment-resistant depression To do this participants will perform a home-based tDCS intervention consisting of 30 minutes sessions, 5 days per week, for 4 weeks. Results should provide critical knowledge regarding home-based therapies for the treatment of resistant depression and evidence on brain mechanisms underlying response to non-invasive brain stimulation.
Imagery Rescripting as Treatment for Depression
Major Depressive DisorderPersistent Depressive DisorderThe goal of this multiple baseline case series study is to test Imagery Rescripting in depression. The main question[s] it aims to answer are: does Imagery Rescripting lead to a reduction of depression and of believability of negative beliefs held by the participants? does Imagery Rescripting also leads to reductions in worrying and brooding? Participants will wait for 6-10 weeks (to assess time effects without treatment), followed by 5 weekly preparation sessions, 8-12 weekly Imagery Rescripting sessions, and 5 weeks post-treatment. Participants will rate the believability of 3-5 core dysfunctional beliefs related to their depression as well as 2 items assessing depression severity on a weekly basis. In addition, they will fill out more extensive questionnaires on depression, worry and brooding before each phase, as well as at 5 weeks post-treatment, and 6 and 12 months follow-up.
Magnetic Randomized Trial in Elderly Depressed
Major Depressive DisorderMajor depressive disorder (MDD) is a common psychiatric condition, mostly treated with antidepressant drugs, which are limited for issues such as refractoriness, adverse effects and drug interactions, especially in the elderly population. In this context, the investigators investigate a non-pharmacological treatment known as recurrent transcranial magnetic stimulation (rTMS) with the theta-burst stimulation (TBS) method for the treatment of geriatric depression. This treatment modality has almost no adverse effects and avoids the risk associated with polypharmacy, providing an interesting alternative to antidepressant treatments. Our aim is to evaluate TBS efficacy in the treatment of geriatric depression in a randomized, double-blind, placebo-controlled clinical trial.

The Effect of Celecoxib on Neuroinflammation in MDD
Major Depressive DisorderNeuroinflammationMajor depressive disorder (MDD) affects an estimated 350 million people worldwide and is a leading contributor to global disease burden. Commonly used monoamine reuptake-inhibiting treatments for depression are suboptimal, resulting in only 30% of patients achieving remission. This may be because monoamine dysfunction is not the primary pathophysiology in all MDD patients. One avenue for the development of novel MDD treatments is through anti-inflammatory drugs; MDD is linked to a pro-inflammatory phenotype characterized by microglial activation, leading to the release of pro-inflammatory cytokines and upregulation of cellular markers including cyclooxygenase-2 (COX-2) and translocator protein (TSPO; a protein located on the outer membrane of microglia). Relevant to this proposal, TSPO can serve as an in vivo marker of neuroinflammation using the newly developed positron emission tomography (PET) tracer for TSPO, [18F]FEPPA. In support of this, a recent [18F]FEPPA PET study found that MDD patients in a current major depressive episode (MDE) had significantly higher TSPO binding in the prefrontal cortex (PFC), anterior cingulate cortex (ACC) and insula, relative to healthy controls. The prefrontal cortex and ACC are both implicated in mood regulation whereas the insula is involved in interoceptive signaling, which is known to be abnormal in MDD. Celecoxib, a selective COX-2 nonsteroidal anti-inflammatory drug (NSAID), is a promising new treatment for neuroinflammation in MDD. Clinical studies have observed that, in a subset of depressed patients, celecoxib treatment reduced depression severity as assessed by the Hamilton Depression Rating Scale (HDRS). While these findings demonstrate that celecoxib reduces symptom severity, PET imaging technology is critical for understanding how celecoxib affects the underlying pathophysiology of depression. Here, the team will investigate neuroinflammation as an underlying pathology in depression and test whether neuroinflammation is reduced by celecoxib in MDD patients. Specifically, in the proposed pilot study, MDD patients in a current MDE will receive [18F]FEPPA PET scans prior to and following 8 weeks of treatment with 400mg/day of celecoxib, with HDRS scores obtained at each time point. The investigators hypothesize that following celecoxib treatment, patients will show a significant reduction in neuroinflammation in the PFC, ACC and insula, which will correlate positively with the reduction in depressive symptoms, as measured by the HDRS. The proposed study will use novel imaging technology, [18F]FEPPA PET, to measure the effects of celecoxib on neuroinflammation in MDD patients. Our results will help to 1) identify neuroinflammation as an underlying pathology in MDD and 2) test whether reduction of inflammation is the mechanism of action of celecoxib. As such, the results of this study will aid in the development of targeted clinical treatments to improve remission rates in MDD patients.

Major Depressive DisorderA 12-week, randomized controlled trial (RCT) will be conducted to explore the effect of add-on sulforaphane (SFN) to selective serotonin reuptake inhibitors (SSRIs) for major depressive disorder (MDD). This study also aims to explore the value of niacin skin flush response test in MDD. One hundred adults diagnosed with MDD will be recruited. Then all the patients will be randomly assigned to SSRI only group and SSRI plus SFN group. Clinical symptoms and side-effects will be evaluated using the 17-Hamilton Depression Rating Scale (17-HDRS), the Hamilton Anxiety Scale (HAMA), Treatment Emergent Symptom Scale (TESS), and Asberg's Rating Scale for Side Effects (SERS) at baseline and weeks 2, 4, 8 and 12 after treatment. Fifty healthy subjects will be recruited as control group. For all subjects, testing of niacin skin flush response and serum levels of nuclear factor erythroid-2-related factor 2(Nrf-2), p-Nrf2, Heme Oxygenase-1 (HO-1), malondialdehyde (MDA) and erythrocyte glutathion peroxidase (GPX) will be performed at baseline and endpoint. The primary outcome is the reduction rate in 17-HDRS total score from baseline to the end of the study. The secondary outcomes include changes in niacin skin flush response test and levels of serum markers. All the data will be analyzed by SPSS software.
