Sex, Hormones and Gamma-Aminobutyric Acid (GABA) in Stress Induced Anhedonia in Depression
Major Depressive DisorderUsing an innovative multi-modal imaging approach, this study investigates the role of the neurochemical gamma-aminobutyric acid (GABA), brain activity, as well as hormones in understanding sex differences in Major Depressive Disorder (MDD). Further, the investigators will link these markers to symptoms of depression.

Efficacy of rTMS in Bipolar Depression
Bipolar DepressionBipolar Disorder is a common condition that is characterized by periods of mood elevation however periods of chronic and recurring depressive episodes are more common and can be severely disabling. Effective treatments exist, however a significant portion of bipolar depressed patients do not respond to, or have difficulty tolerating many of these interventions. Repetitive Transcranial Magnetic Stimulation (rTMS) is a non-invasive neuromodulatory technique that is effective in major depression and there is evidence for its efficacy in bipolar depression which needs to be assessed in larger randomized controlled trials. This study is a randomised, double-blind, sham-controlled trial over four weeks. The primary objective is to assess improvement in depressive symptoms in acute bipolar depressed patients on treatment with intermittent Theta-Burst Stimulation (iTBS) in comparison to sham-rTMS.

Treatment of Depression With Connectivity Guided Robotically Delivered rTMS
Major Depressive DisorderThe purpose of this study is to determine the clinical effects (if any) of connectivity-guided repetitive transcranial magnetic stimulation (rTMS) in the treatment of major depressive disorder (MDD) to provide clues about the ideal neural networks to target for more robust clinical outcomes, and to identify potential biomarkers of treatment response including changes in brain network connectivity.

Acute Myocardial Necrosis and Depression: Antiplatelet Effect of Reuptake Inhibition of Serotonin...
DepressionCoronary Artery DiseasePrimary purpose: To evaluate the evolution in time of the antiaggregant platelet effect of sertraline (SSRI) compared to placebo in depressive patients with ACS (Acute Coronary Syndrome) and treated as recommended by a double antiplatelet therapy, aspirin and clopidogrel. Hypothesis: The benefits of SSRIs observed in depressive patients with ACS are related to an antiplatelet effect.

NeoSync TMS Treatment for Bipolar I Depression
Major Depressive EpisodeBipolar Depression2 moreThis study is designed to evaluate the safety and preliminary efficacy of synchronized transcranial magnetic stimulation (sTMS) using the NeoSync EEG Synchronized TMS device (NEST) in subjects with Bipolar Disorder type I in a Major Depressive Episode. This is an open label study in which subjects will receive treatment 5 days per week for 6 weeks.

Group Metacognitive Therapy for Anxiety and Depression in Cancer Survivors
CancerAnxiety2 moreThis study aims to test the potential of group metacognitive therapy in alleviating emotional distress in cancer survivors. The investigators aim to find out if a group based approach is acceptable to patients and feasible to deliver in a routine clinical health psychology service.

Is Vitamin D Insufficiency and Deficiency Associated With Antepartum and Postpartum Depression?...
DepressionPostpartum DepressionOur primary aim is to evaluate whether Vitamin D deficiency causes depressive symptoms in antepartum and postpartum depression and whether early correction of Vitamin D deficiency improves these symptoms. Our secondary aims evaluate maternal and fetal outcomes including antepartum, intrapartum, and immediate postpartum complications. We are also evaluating the effectiveness of a common vitamin D treatment regimen used outside of pregnancy.

tDCS in Parkinson's Disease With Depression
DepressionParkinson'sParkinson's disease (PD) is a progressive neurological disease that has effects on both movement and mental health. One of the most common mental health complications of PD is depression. Up to 30% of Parkinson's patients will experience depression at some point. We aim to investigate whether transcranial direct current stimulation (tDCS), a type of electrical stimulation for the brain, can improve depression in PD as well as improve motor function in PD.

The Effect of Melatonin on Depression, Anxiety, Cognitive Function and Sleep Disturbances in Breast...
Breast CancerDepressionThe purpose of this study is to investigate the effect of 6 mg melatonin daily for 1 week preoperatively to 12 weeks postoperatively on depressive symptoms, anxiety, cognitive function and sleep disturbances in breast cancer patients. Furthermore the investigators will examine whether a specific clock-gene (HPER3) is correlated with an increased risk of depression, sleep disturbances or cognitive dysfunction.

Prefrontal Transcranial Random Noise Stimulation in Patients With Depression
DepressionTranscranial random noise stimulation is used to stimulate the prefrontal cortices in patients with depression. It's a placebo-controlled two-arm study.
