This prospective observational study (ADeSS-Study3) investigates candidate biomarkers prospectively predicting response to antidepressant medications and prognosis in major depressive disorder (MDD). Currently, about half of MDD patients will not respond to the first course of selective serotonin reuptake inhibitors (SSRIs), while more than 40% will also not achieve remission after a second round of another SSRI. There are functional magnetic resonance imaging (fMRI) measures in several brain regions, showing clinical potential as predictors of response and non-response to SSRIs. The overall aim of the study is to identify the neural signatures prospectively predicting poor prognosis in MDD patients after receiving four months of treatment in UK primary care. Specifically, it looks to evaluate four fMRI measures: 1) self-blame-selective subgenual cortex and ventral striatum connectivity with the right anterior temporal lobe; 2) pregenual anterior cingulate cortex activity in response to implicit emotional facial expressions; 3) amygdala activation in response to implicit emotional facial expressions; and 4) subgenual cingulate seed-based resting state. In addition, a more specific objective of the study is to provide the proof-of-concept for using fMRI to prospectively predict which MDD patients will not benefit from SSRI antidepressant treatments in UK primary care. The long-term translational aim is to identify such patients and provide them with alternative treatments without delay by informing a decision support system with the information provided by these candidate biomarkers. This study is linked to the Antidepressant Advisor Trial (ADeSS-Study 1: NCT03628027), in which the feasibility is evaluated of a novel computerised decision support system for antidepressant prescribing in MDD patients in a UK primary care setting.
The primary purpose of this study is to evaluate the efficacy of flexibly dosed esketamine nasal spray compared with quetiapine extended-release (XR), both in combination with a continuing selective serotonin reuptake inhibitor/serotonin-norepinephrine reuptake inhibitor (SSRI/SNRI), in achieving remission in participants who have treatment-resistant major depressive disorder (MDD) with a current moderate to severe depressive episode.
This research aims to elucidate mechanisms through which change occurs during cognitive behavior therapy (CBT) for depression. Assessing meta-cognitive processes of self-knowledge (top-down), electrophysiological and behavioral correlates of emotion processing (bottom-up), and their relation to treatment outcome will provide new insights into the mechanisms of emotion regulation deficits in depression. It will also contribute toward the clinical goal of identifying patients who may benefit most from CBT for unipolar depression.
This study aims to investigate the effects of the Switch intervention on motivation and associated processes and explore the dynamics between the processes. A single case approach is followed, with a pre-post and follow-up assessment design, and continuous ambulatory assessments (experience sampling method (ESM) and step count).
The goal of this study is to determine whether antidepressant placebo effects and contextual cues broadly, can be blocked by one single dose of the µ-opioid antagonist naltrexone. To test this hypothesis, un-medicated, patients with MDD completed a randomized, double-blind, placebo-controlled, cross-over study of 50mg of the µ-opioid antagonist naltrexone or matching placebo, immediately before a Pharmaco-fMRI scanning session.
The researchers in this trial want to learn more about the drug Laif® 900 in preventing the return of signs and symptoms of depressions (also called relapse) in patients suffering from moderate depression episodes. The study drug Laif® 900 is based on Hypericumextract made from the plant St. John wort. Patients will be accepted to take part in the study if they have 20-24 points on the Hamilton Depression Rating Scale (HAM-D) which is a questionnaire helping the doctor to rate the severity of the depression and includes questions on patient's mood, sleep difficulties, agitation, anxiety and weight loss. About 400 patients will be enrolled into the first part of the study and will be treated for 12 weeks with Laif® 900 capsule once daily. Only patients with an improved HAM-D score by 50% will stay in the study and continue with the second part of the study which will last for 24 weeks. In this second part of the study patients will receive either Laif® 900 capsule once daily or an inactive tablet (placebo). Neither the treating doctor nor the patient will know which patient receives the Laif® 900 or placebo. At the end of the study the researcher will assess the effectiveness of the study drug in prevention relapse of depression episodes and will also have more information on the safety of the study drug.
The aim of the present observational study is to assess the clinical response, functional impairment and quality of life in outpatients with Major Depressive Disorder who demonstrated an initial positive response to the acute treatment with Trazodone once-a-day monotherapy, for up to 24 weeks.
This study evaluates the effectiveness of vortioxetine on depressive symptoms in patients with depression and early dementia
The purpose of this study is to evaluate the safety and tolerability of flexible doses of vortioxetine (5 - 20 mg/day) over a period of 12 weeks in patients with depression in India
