Filter by:The purpose of this prospective randomized clinical trial is to determine if patients receiving ketamine as a part of general anesthesia during electroconvulsive therapy (ECT) rather than standard of care will have improvement in symptoms of depression after a course of ECT treatments. The investigators hypothesize that utilization of ketamine for induction of general anesthesia during ECT treatments will improve symptoms of depression better than standard care. This study is ONLY open to patients eligible to receive healthcare services through the Department of Veterans Affairs at the VA Puget Sound, which means service in the active military, naval or air service or separation under any condition other than dishonorable.

Depression currently affects close to 2 million Canadians and is the leading cause of disability worldwide. Pharmacological treatments (antidepressant medication) and psychological treatments such as cognitive-behavioural therapy are available for depression, but the majority of those who receive treatment have an unsatisfactory response. On average, the combination of pharmacological and psychological treatment achieves better results than either treatment alone. However, the apparently superior results of combination treatment may be due to the fact that different individuals preferentially respond to pharmacological or psychological treatment. The invesitagtors have discovered several clinical factors and biomarkers that predict poor response to commonly used antidepressant medication: history of childhood maltreatment, loss of interest and reduced activity, a biomarker of systemic inflammation, and a genetic marker of sensitivity to environment. Indirect evidence suggests that the same factors may indicate the need for psychological treatment, but their usefulness as differential predictors of psychological and pharmacological treatment outcomes remains to be established. The investigators will test the hypothesis that a pre-determined set of clinical variables (history of childhood maltreatment, loss of interest and reduced activity) and biomarkers (serum C-reactive protein, a marker of systemic inflammation, and short alleles of the serotonin transporter gene promoter polymorphism) differentially predicts response to antidepressants and to cognitive-behavioural psychotherapy with clinically significant accuracy. If this hypothesis is supported, the resulting predictor will allow personalized selection of treatment for depression, leading to improved outcomes and healthcare efficiency. Additional objectives include replication of additional predictors and integrative analyses aimed at refining the treatment choice algorithms.
This is a study to characterise the role of inflammatory processes in depression. There is compelling evidence that inflammation is often associated with, and can cause, depression. It is currently less clear that antiinflammatory drugs have meaningful antidepressant effect. One of the goals is to identify the subset of depressed patients that is most likely to respond better to an antiinflammatory drug than to a conventional antidepressant. The investigators will therefore undertake a study of patients with a diagnosis of major depressive disorder including four groups: i) incompletely responsive patients who have demonstrated failure to respond consistently or completely to standard treatment, ii) those who have responded well to treatment and are not currently depressed, iii) untreated patients who are currently depressed, iv) healthy volunteers with no history of depression. Participants will undergo a clinical assessment, an interview with a trained member of the research team and will complete self-rated questionnaires. Investigators will collect blood and saliva samples to measure certain immune markers. They will also perform magnetic resonance imaging (MRI) scans to look for MRI markers in the brain and investigate brain inflammation in a subsample of these patients using positron emission topography (PET) and cerebrospinal fluid (CSF) sampling (also called lumbar puncture).
The purpose of this study is to explore patterns of Brain Network Activation (BNA) changes from baseline to endpoint on 1) efficacy of core symptoms of Major Depressive Disorder (MDD) and 2) improvement of cognitive dysfunction with acute treatment with flexible dose vortioxetine in adult outpatients with MDD and subjective complaints of cognitive dysfunction.
In the present study researchers aim to investigate the effectiveness of an intervention combining emotion regulation and mindfulness skills in a single 10-week program. A total of 75 individuals with major depressive disorder (MDD) diagnosis in complete or partial remission participated in this randomized controlled trial (RCT) comparing an intervention including emotion regulation and mindfulness skills (ER+M) with a psychoeducative program. After treatment, participants were followed for a 1-year period. Researchers results indicate that ER+M was not more effective than the treatment used with the control group in preventing depression relapse. Participants allocated to the ER+M group showed a significant decrease on global psychiatric symptoms, whereas those in the control group did not. Further studies are needed in order to better determine the combined effects of mindfulness and behavioral activation.
The purpose of this study is to validate a set of signatures, based on a panel of proteomic markers, that discriminate BDI, BDII, and MDD in people seeking treatment for a depressive episode.
Individuals with Late Life Depression (LLD) often have cognitive problems, particularly problems with memory, attention, and problem solving, all of which contribute to antidepressant non-response. Our group and others have shown that decreased thinking speed is the central cause of functional problems in patients with LLD. Similarly, decreased walking speed is associated with depression and carries additional risk for falls, hospitalization, and death. Available evidence suggests that declining functionality in the brain's dopamine system contributes to age-related cognitive and motor slowing. The central hypothesis of this R61/R33 Phased Innovation Award is that by enhancing dopamine functioning in the brain and improving cognitive and motor slowing, administration of carbidopa/levodopa (L-DOPA) will improve depressive symptoms in older adults.
To evaluate the efficacy and safety of AXS-05 relative to bupropion in subjects with treatment resistant major depressive disorder (MDD). This is a randomized, double-blind, active-controlled, 12-week, two-period study consisting of an open-label, bupropion lead-in period, and a double-blind treatment period. The trial is being conducted in subjects with treatment resistant MDD. Subjects will be considered to have treatment resistant MDD if they have had a historical inadequate response to 1 or 2 antidepressant treatments and a prospective inadequate response to treatment with bupropion during the open-label, lead-in period.
Acute aerobic exercise improves affective stats in patients with mental illnesses. Brain derived neurotropic factor (BDNF) may be a biological mechanism that contributes to the affective benefits. The magnitude of the increase of serum BDNF might be exercise intensity dependent, but no study has compared low high-aerobic-intensity training at 90-95 % of the maximal heart rate (HRmax) with long-slow-distance training at 70 % of the HRmax in patients with depression. The aim of this study is to compare changes in serum BDNF levels after high-aerobic-intensity training and long-slow-distance training in a intra-individual design in patients suffering from depression. The results will give indications of a possible difference in BDNF response between aerobic intensities and may be uses as pilot data for calculating sample size.
Depression is one of the most common symptoms of multiple sclerosis (MS) with a life-time prevalence of major depressive disorder (MDD) of up to 50%. Depression occurs more frequently in MS than in other chronic diseases including other neurological and inflammatory disorders and may contribute to lower quality of life, cognitive problems, difficulties at work, and poorer long term health outcomes. Despite its clinical relevance, the biological mechanisms which may be responsible for the high risk for MS patients to develop depression are unknown. In this observational study, investigators explore the molecular mechanisms responsible for the impaired regulation of immune cells in relapsing-remitting (RR) MS patients with depression. Investigators will compare the molecular and phenotypical profile of immune cells obtained from RRMS patients with clinical depression (n=50), matched MS patients who do not suffer from depression (n=50) as well as matched healthy controls (n=50) and matched patients with depression but without a comorbid neurological disorder (n=50).
