Filter by:This pilot study may yield important research findings on how to adapt exercise treatment for depression among adolescents. Potential public health benefits from this study include a reduction of adolescent depression and problems associated with untreated depression in young adults including suicide, substance abuse, cigarette smoking, teen pregnancy, impaired psychosocial functioning and school failure. In addition, because this study prescribes physical activity as a treatment for depression, additional public health benefits may include a reduction in chronic diseases such as obesity, diabetes and heart disease, all of which are associated with sedentary behavior.
In treatment-resistant depression, electroconvulsive therapy (ECT) has been shown to effectively reduce depressive symptoms, though the underlying neurobiological mechanism is still unclear. The serotonergic system, and in particular the inhibitory serotonin-1A (5-HT1A) receptor, appears to be significantly involved in the effectiveness of ECT. The aim of the study is to assess the effects of ECT on the 5-HT1A receptor binding potential (BPND) and distribution in humans in vivo using positron emission tomography (PET) and the radioligand [carbonyl-11C]WAY-100635. 12 patients suffering from severe, therapy-resistant unipolar depression will undergo 3 PET scans, two of these scans taking place before the ECT treatment, consisting of 6-14 ECTs, the third scan taking place after the ECT treatment. This imaging study hypothesizes that upon completion of the ECT, the overall 5-HT1A receptor BPND in the brain of depressed patients will significantly change. This study would be the first to demonstrate an effect of electroconvulsive therapy on the 5-HT1A receptor binding in humans in vivo. Given the involvement of the 5-HT1A receptor in the pathophysiology of mood disorders, the present study would be an important step towards a better understanding of antidepressant treatment and treatment response. By comparing treatment effect and the underlying biological mechanism, the study might help to identify biomarkers that distinguish patients who are likely to benefit from ECT from patients who will rather be non-responders. Finally, by investigating the role of the 5-HT1A receptor in ECT, is highly discussed relevance for antidepressant action will be further elucidated and might prepare the ground for new therapeutic strategies.
This treatment pilot study will investigate clinical efficacy and adverse effects of magnetic seizure therapy (MST) in patients currently experiencing a unipolar or bipolar depressive episode. The investigators will perform add-on tests to assess clinical and cognitive response to treatment. It is hypothesized that MST will have an antidepressant efficacy with a beneficial neurocognitive adverse effect profile.
This study is intended to evaluate the efficacy and safety of lamotrigine as an antidepressant augmentation agent in a sample of individuals with major depression and a history of both prior non-response and prospective failure to respond to at least one adequate trial of an antidepressant (for a total of two failed trials).
The purpose of this study is to assess the efficacy of add-on therapy with repetitive Transcranial Magnetic Stimulation (rTMS) and venlafaxine in the treatment of major depressive disorders compared to venlafaxine only (the optimal medication) and to rTMS only.
Recently published work has examined the effects of "atypical antipsychotics" in SSRI-treatment resistant patients. In these studies, patients with unipolar depression who were treated with SSRI's, but not responsive to treatment after 4 or more weeks, were supplemented with an atypical. The atypical antipsychotics were found to diminish depression symptoms, as well as benefit sleep quality. We propose a similar study with Quetiapine XR, focusing on thinking processes, mood and anxiety. Patients with depression who are SSRI treatment resistant will be treated with Quetiapine. Cognition will be evaluated in the UBC Mood Disorders Clinic two times: first before Quetiapine addition, then after 8 weeks. Depression symptoms and other measurements will be done at the 9 time points: before Quetiapine, and each week after treatment has begun. The primary purpose of this study is to evaluate the superiority of Quetiapine XR compared to placebo as augmentation therapy in treatment of anxiety and depressive symptoms in SSRI-nonresponsive unipolar patients. Secondarily, we would like to evaluate the safety and tolerability of quetiapine as augmentation therapy in SSRI-nonresponsive unipolar patients.
The purpose of the study is to test the efficacy of a psychoeducational group program on unipolar depression
Our goal is to study pharmacogenetics in Mexican-Americans, using depression treatments as a proof of the concept that pharmacogenetic approaches can be used to optimize treatment strategies for common and complex disorders in this population.
This study is being conducted to determine the clinical response rate for the regimen of L-methionine, betaine and folate for unipolar depression.
Repetitive Transcranial Magnetic Stimulation (rTMS) can improve mood and decrease sadness in patients with depression. In this study, the investigators seek to increase their understanding about how rTMS improves depression, and to determine which form of rTMS is most effective for depression, when used in combination with antidepressant medication.
