Establishing Multimodal Brain Biomarkers for Treatment Selection in Depression
Major Depressive DisorderChronic Major Depression1 moreThe purpose of the study is to identify brain biomarkers and characteristics that predict individual responses to treatment of major depression with the antidepressant drug sertraline (tradename Zoloft), a common selective serotonin reuptake inhibitor (SSRI) antidepressant. Our central hypothesis is that brain activity and connections jointly measured with functional magnetic resonance imaging (fMRI) and electroencephalogram (EEG) will be able to predict an individual's response to sertraline treatment.

Deep rTMS for Depression in Older Adults: A Pilot Study
Major Depressive DisorderThis study aims to: (1) assess the feasibility and tolerability of two active dTMS coils - H4 and H7 - in older adults with depression; and (2) clinical response measured by change from baseline on the Hamilton Depression Rating Scale- 24 item; changes in cognitive function through neuropsychological assessment; and changes in regional electrophysiological activity and functional connectivity indexed by EEG. Through a parallel design, participants will complete a four-week course of five dTMS sessions per week, for a total of 20 stimulation sessions. Participants will be randomly assigned to either coil (H4 or H7) and will complete questionnaires examining side effects, mental health symptoms, and cognition. Participant EEG data will be measured and collected at baseline and at the end of each week. Collectively, the study will address the absolute and differential feasibility and tolerability of the two active coils to provide preliminary data for a future randomized controlled trial comparing one or both of these novel interventions to the established H1-coil and a sham stimulation (placebo) control.

Alpha-Amino-3-Hydroxy-5-Methyl-4- Isoxazole Propionic Acid Receptor Components of the Anti-Depressant...
Depressive DisorderMajor2 moreThe proposed study will assess the combined effect of perampanel and ketamine on the anti-depressant response in individuals with treatment resistant depression. The purpose of this study is to test the hypothesis that stimulation of Alpha-Amino-3-Hydroxy-5-Methyl-4- Isoxazole Propionic Acid receptors (AMPAR) is critical to the anti-depressant response of ketamine.

The Effects of Psilocybin on Self-Focus and Self-Related Processing in Treatment Resistant MDD
Treatment-Resistant Major Depressive DisorderThis open-label fMRI study will assess the effects of a single dose of psilocybin on rumination and the neural correlates of rumination in individuals with treatment-resistant major depressive disorder.

Predictors of Cognitive Outcomes in Geriatric Depression
Major Depressive DisorderNeuroticism2 moreThis study will focus on examining effects of stress on long-term mood and cognitive outcomes of late-life depression. It will also example the neural underpinnings of these changes using structural and functional brain imaging. Understanding how effects of stress in older depressed adults, as well as factors that might minimize those effects, lead to particular mood and cognitive outcomes will inform future development of novel prevention strategies.

Using Electrophysiology to Index Non-invasive Brain Stimulation Effects on Reward System Functioning...
Major Depressive DisorderDepression is a leading cause of morbidity and mortality, conferring substantial healthcare and societal costs. By studying methods to non-invasively target neural circuitry involved in reward responsivity, information generated by this project will improve understanding of the circuit alterations that underlie motivation and pleasure deficits in depression, and could also lead to the development of biologically-based markers of neurostimulation-based treatment response.

Multi-domain Psychoeducation Self-management Program for Adults With MDD in Singapore
Major Depressive DisorderThis is a single-centre, two-arm, unblinded pilot randomised controlled trial study on 60 participants (30 in each arm) from the community mental health service (CMHS) centre within a social service agency in Singapore based on inclusion criteria. The study will examine the effects of a 5-sessions of Multi-domain Psychoeducation Self-management Programme and treatment-as-usual) over 5 weeks or control (treatment-as-usual) group.

Enhanced Measurement-Based Care Effectiveness for Depression (EMBED) Study
Major Depressive DisorderMeasurement-based care (MBC) is an evidence-based practice that incorporates routine outcome assessment using validated rating scales to guide collaborative clinical decision-making. Although MBC results in improved outcomes for patients with major depressive disorder (MDD), there are barriers to its broad implementation in clinical settings. The use of "enhanced" MBC (eMBC), with mobile apps that allow patients to track outcomes and engage in self-management via WeChat, may address some of these barriers. The investigators hypothesize that implementation with eMBC using WeChat will be superior to standard MBC implementation using paper-pencil assessments at the clinic, for both implementation and clinical outcomes.

Peripheral Neuroimmune Mechanisms of Hyperthermia
HyperthermiaMajor Depressive Disorder1 moreThe goal of this study is to examine how whole-body hyperthermia affects the thermoinflammatory profile, which includes the combined immune and heat shock response, in patients with depression and whether these changes correlate with decreased depression in individuals with Major Depressive Disorder.

Major Depressive DisorderA randomized, controlled, prospective, multicenter, patient and rater blinded study with 2 arms: Treatment as Usual (TAU) and Predictix Guided Treatment (PGT). The study will compare the rate of treatment response and remission among both groups; TAU vs PGT.
