aiTBS for Relieving NSSI in Depressive Patients
Major Depressive DisorderBipolar DepressionRepetitive transcranial magnetic stimulation (rTMS) has been successfully used to help patients with treatment resistant depression. However, its role in alleviating self injuries without suicidal ideation remained uncertain. This trial will compare the effectiveness of active accelerated intermittent theta burst stimulation (aiTBS) rTMS to a placebo control on non-suicidal self injury (NSSI) in patients with unipolar disorder and bipolar disorder.
Brain Insulin Resistance in Mood Disorders
Major Depressive DisorderBipolar Disorder2 moreThe overarching aim of the study is to determine the role of insulin signaling on the neurobiological substrates subserving anhedonia within individuals with mood disorders (i.e., Bipolar Disorder (BD) and Major Depressive Disorder (MDD)). Specific aims include: Molecular: Assessment of components of the insulin cascade, as well as of anhedonia and reward-related processes, using a proteomics and gene expression approach; Physiology: Measurement of peripheral sensitivity to insulin and metabolic correlates, including body mass index and dyslipidemia; Neural Circuits: Evaluation of the insulin sensitivity of prefrontal (e.g. prefrontal cortex) and striatal (e.g. nucleus accumbens, ventral tegmental area) networks in the resting-state and during an effort-based decision making test, using acutely administered intranasal insulin and functional magnetic resonance imaging (fMRI); Behavioral: Measurement of willingness to make effort for rewards, as well as of other components of reward response and anhedonia, using validated behavioral tasks and clinical scales (e.g. Snaith-Hamilton Pleasure Scale - SHPS). This initiative represents a proof-of-concept study that insulin is important to anhedonia, neurocognitive functioning, and behavioural deficits in MDD, representing a novel and safe therapeutic avenue.
Xenon Inhalation Therapy for Major Depressive Disorder and Bipolar Disorder
Major Depressive DisorderBipolar DepressionThe investigators will test the hypothesis that inhaled xenon will produce a rapid improvement in depressive symptoms in patients suffering from treatment-resistant depression. Specifically, the investigators will conduct a parallel randomized, double-blind crossover study that will compare the effects of xenon-oxygen (35:65 ratio by volume) added to treatment as usual (X-TAU group) to the effects of nitrogen-oxygen (35:65 ratio by volume) added to treatment as usual (N-TAU group). A total of 20 severely depressed patients, 10 with major depressive disorder (MDD) and 10 with Bipolar Depression (BP), will be exposed in random order to N-TAU and X-TAU in a double-blind protocol.
Scopolamine in Bipolar Depression
Bipolar Disorder DepressionThis is a single-site, randomised, double-blind, placebo-controlled, parallel, phase IIb clinical trial. The primary objective of the SCOPE-BD study is to investigate the efficacy and safety of IV Scopolamine, compared to placebo, in reducing severity of depression in individuals with bipolar disorder who are experiencing a depressive episode of at least moderate severity
Efficacy of Convulsive Therapies for Bipolar Depression
Bipolar DisorderBipolar Depression2 moreThis trial aims to assess the efficacy and tolerability of Magnetic Seizure Therapy (MST) as an alternative to electroconvulsive therapy (ECT) for Bipolar Disorder (BD). Research indicates that the prevalence of treatment resistance in bipolar depression is twice that of unipolar depression. The limited effectiveness of current treatments for bipolar depression coupled with the medical and economic burden associated with the disorder engenders a need for novel therapeutic interventions that can provide greater response and remission rates.
Adjunctive Allogeneic Mesenchymal Stem Cells for Treatment-resistant Bipolar Depression
Treatment-resistant Bipolar DepressionThe overall objective of the investigators is to assess the therapeutic efficacy and tolerability of Allogeneic Bone Marrow Derived Multipotent Mesenchymal Stromal Cells (MSCs) isolated from hematogenous bone marrow for treatment of treatment-resistant bipolar depression patient (TRBD).
The CAG Bipolar the CAG Bipolar RCT
Bipolar DisorderThe CAG Bipolar study is a large-scale pragmatic randomized controlled trial aiming to investigate whether specialized and more centralized treatment (into a clinical academic group (CAG)) improves lives and outcomes for patients with bipolar disorder (N= 1000 patients).
COMpassion for Psychiatric Disorders And Self-Stigma
Bipolar DisorderSchizophrenia3 morePeople with mental disorders face frequent stigmatizing attitudes and behaviors from others . In response to this, they tend to isolate themselves, with the risk of impeding care and the process of recovery and integration into society . Stigmatization can also be assimilated by patients themselves - i.e. self-stigma. Self-stigma is involved in diminished coping skills that lead to social avoidance and difficulties in adhering to care . Reducing self-stigma and its emotional corollary, shame, is thus crucial to attenuate the disability associated with mental illness. Shame is inherent to self-stigma and leads to difficulties in adhering to care as well as greater severity of clinical presentations . Compassion Focused Therapy (CFT) is a third wave cognitive behavioral therapy that targets shame reduction and hostile self-to-self relationship and allows for symptom improvement while increasing self-compassion, a major resilience factor . Although shame is a prominent part of the concept of self-stigma, the efficacy of CFT has never been evaluated in individuals with high levels of self-stigma. In this study, the investigators will evaluate the efficacy and acceptability of a group based CFT program on decreasing self-stigma, compared to treatment as usual (TAU) and a psychoeducation program whose efficacy has been assessed in a previous trial.
Electro-Magnetic Convulsive Therapies for Depression: a Non-inferiority Study
Major Depressive DisorderBipolar DepressionThis study aims to compare the efficacy and safety profile of Magnetic Seizure Therapy and Electroconvulsive therapy.
Post-Hospital Intervention for Veterans With Comorbid Bipolar and Substance Use Disorders
Bipolar DisorderSubstance Use DisordersThis trial aims to evaluate the effectiveness of a novel intervention for Veterans with co-occurring bipolar and substance use disorders following a psychiatric hospitalization. Half of the participants will receive a specialized psychosocial intervention program, while the other half will receive an enhanced safety monitoring program, both provided in addition to their routine care.
