Mood and Thought Process Study
Depression in RemissionDepressive Symptoms1 moreThe primary objective for this project is to test whether affective executive functioning is a mechanism of action of mindfulness-based cognitive therapy and Wellness for Wellbeing. The main questions it aims to answer are: Test the effect of MBCT vs. Wellness for Wellbeing on affective inhibition (i.e., emotionally valenced inhibition as measured via the affective Go/No Go task) using an RCT. Test the effect of MBCT vs. Wellness for Wellbeing on (a) affective updating and (b) affective shifting. Outcomes will be measured with the affective n-Back and the affective Internal Switching Task, respectively. 3a) The investigators will examine whether depression symptom severity co-varies with change in affective executive functioning (i.e., affecting inhibition, shifting, and updating) over time. 3b) The investigators will examine whether compliance with treatment protocol (e.g., number of classes attended, amount of home practice) predicts endpoint executive functioning. Participants will complete surveys, interviews, and computer tasks, and will be randomized to either Mindfulness-Based Cognitive Therapy or Wellness for Wellbeing.
Attention Training Technique in Treatment of Anxiety and Depression in Coronary Heart Disease Patients...
DepressionAnxiety1 moreAnxiety and depression are associated with work disability, lower participation rate in cardiac rehabilitation and unfavourable life style changes following a coronary heart disease (CHD) event. The prevalence of clinically significant symptoms of depression and anxiety in CHD patients has been estimated to 30-50%. Furthermore, depression and anxiety are associated with a significant increased risk of subsequent major adverse cardiovascular events and mortality in CHD patients. Psychological interventions for anxiety and depression in CHD patients have demonstrated small and uncertain effects of symptoms, and no effect on cardiovascular outcomes. Therefore, testing the effectiveness of specific psychological interventions that may affect central mechanisms for cardiovascular outcomes, has been requested. The Attention training (ATT) Study is a randomized controlled trial comparing group-attention training to wait-list control in 64 patients who experience significant anxiety and depression after a CHD event. It will also be explored whether reduction in psychological symptoms is correlated with changes in biological markers with a potential link to cardiovascular outcomes.
Treatment for Rehabilitation of Action Cognition in Depression
DepressionThe present research study investigates the effects of a brief dynamic imagery intervention added to a short behavioral activation treatment on the treatment acceptability, feasibility, and primary efficacy for individuals with depression. Behavioral activation treatment is a standard treatment for depression. To enhance behavioral activation treatment acceptance and efficacy, a dynamic imagery intervention was added to augment the motor component of imagery and memories. Two types of treatment were compared: (1) behavioral activation treatment and (2) behavioral activation treatment plus dynamic imagery. The behavioral activation treatment is a short 8-session intervention based on a dynamic imagery procedure for enhancing the recruitment of motor activation in cognitive processing. 110 participants will be randomized into two groups. Half will be randomized to standard behavioral activation treatment and a half to behavioral activation treatment plus imagery treatment. Participants complete the assessment before, during (weekly), and after treatment. Follow-up will be measured at 3 months after the end of the treatment.
Effect of ON-tDCS on Memory Function Improvement and Related Circuits in Stable Depression Patients...
DepressionSo far, antidepressant drugs have limited memory improvement. Transcranial direct current stimulation, as a non-invasive and safe neuroregulatory technique, is a new direction to improve memory.In this study, transcranial direct current stimulation of the greater occipital nerve was used to explore the effect of improving memory function in patients with stable depression, and related studies were conducted on the locus coeruleus-noadrenal loop and the functional connection between locus coeruleus, hippocampus and amygdala.
ELE-101 Safety & Tolerability Study in Healthy Participants and Patients With Depression
Healthy VolunteersMajor Depressive Disorder1 moreA study to assess the safety and tolerability of a drug called ELE-101 and see how the body absorbs and removes the drug and how it affects the body in healthy adult participants (Part 1) and in patients with depression (Part 2).
Fluoxetine Treatment of Depression in Down Syndrome
Down SyndromeDepressionThe purpose of the study is to do a preliminary assessment of whether fluoxetine is effective, safe, and tolerable for the treatment of depression in adults with Down syndrome.
Expanding First-line Options for Depression and Matching Treatments to Patients: Hatha Yoga vs....
DepressionThis is a parallel group study design. The investigators propose to compare an online, synchronous group-based yoga intervention developed for individuals with depression to an online, synchronous individualized, evidence-based behavioral therapy for depression, or Brief Behavioral Activation Treatment for Depression (BA). This study is a multi-site randomized trial of adults with clinically significant depressive symptoms. Participants (N=518) will be randomized in an equal allocation ratio (i.e., 1:1) across two intervention groups: yoga and BA. Interventions will be provided over a 12-week period and assessments will occur at baseline (week 0), week 6, week 12, week 18, and week 24.
A Study of Aticaprant in Adult and Elderly Participants With Major Depressive Disorder (MDD)
Depressive DisorderMajorThe purpose of this study is to assess the long-term safety and tolerability of aticaprant administered as adjunctive therapy to a current antidepressant (selective serotonin reuptake inhibitor [SSRI] or serotonin and norepinephrine reuptake inhibitor [SNRI]) in all participants with major depressive disorder (MDD).
Multi-factor Model Constraction for Early Warning and Diagnosis of MDD
Major Depressive DisorderBipolar Disorder1 moreCurrent research on the pathogenesis of depression shows that imbalanced inflammatory factors are closely related to Major Depressive Disorder(MDD). As reported, physical exercise, Ω-3 fatty acids, and sulforaphane can be complementary therapies for moderate-to-severe depression. In addition, imaging studies have found changes in the structure and functional connectivity of the brain. Therefore, this study intends to collect clinical and biological information from patients with depression and healthy controls to establish a multi-factor model for early warning and diagnosis of major depressive disorder
Feasibility Study of an Online Physical Activity Intervention for Youth With Depression
Low MoodMild Depression3 morePhysical activity (PA) has recently been established as both a primary intervention for mild to moderate, and a secondary therapy for moderate to severe Major Depressive Disorder (MDD; Fortier et al., 2020). Those with mental health disorders do not on average achieve recommended levels of PA (Hallgren et al., 2016), and exercise prescription is extremely lacking in clinical care (Stanton, Reaburn, & Happell, 2015; Stanton et al., 2018). Theory-based behavioural interventions have proven to be an effective tool for improving physical activity levels in clinical populations (Glowacki, et al., 2017; Stanton et al., 2015). More research is needed to understand PA intervention effectiveness for MDD patients (Glowacki et al., 2017), support integration of such behavioural treatments with primary care (Lederman et al., 2017), and address growing concerns regarding mental health during the global pandemic and beyond (Boyce, 2021). This community-based study examines the feasibility of a co-designed, 10-week, asynchronous, web-based beta platform PA intervention for patients with experience of low mood and/or mild to moderate depression, and will provide important parameters for a future randomized-controlled trial (RCT). Primary outcome measures will focus on acceptability and feasibility, including recruitment and retention rates. Secondary measures will include physical activity and depression symptom severity. Behavioural predictors of PA are to be evaluated as tertiary outcomes. Questionnaires will include an adapted participant experience measure, Godin Leisure-Time Exercise Questionnaire, and the Patient Health Questionnaire-9. This study features a controlled baseline, post-intervention evaluative design with an embedded quantitative process evaluation with a waitlist control. Participants will be young adults with experience of low mood and/or mild to moderate depression, 19-30 years of age, with access to a device with internet, English speaking, living within British Columbia, CAN., and falling below the minimum Canadian recommendations for PA. Study recruitment will primarily be facilitated by multiple youth mental health primary and community care clinics. This study will contribute to understanding of acceptable, efficacious, behaviour-based and mobile health intervention approaches for young adults with depression. It will also provide young people with a platform to share invaluable feedback to direct innovations in their own alternative care and mental health treatment. If outcome benchmarks set based on previous literature are met or exceeded for each of recruitment, retention, and acceptability, and depressive symptoms trend downwards for intervention participants, then a future randomized controlled trial exploring principally mental health outcomes will be recommended.
