This study addresses the unmet medical problem of insufficient treatment of late life depression (LLD). Compared with depression in early adulthood, treatment options of LLD are limited. This trial is the first confirmatory multicentre study to test the efficacy of an LLD-adapted cognitive behavioural therapy (CBT) program. It will test the hypothesis, that LLD-specific cognitive behavioural therapy (CBT) is superior to unspecific supportive intervention (SUI) with regard to reducing symptoms of depression over the course of 6 months. Secondary goals are to test the efficacy of LLD-CBT in comparison with SUI on patient reported outcome in major depressive disorders (PRO-MDD), anxiety, cognition, quality of life, overall health status, sleep and global clinical impression.
The primary purpose of this study is to investigate neural mechanisms and predictors of treatment outcome in Mindfulness-Based Cognitive Therapy (MBCT) for recurrent Major Depressive Disorder.
We hope to demonstrate that magnetic resonance spectroscopy can detect brain concentration levels of paroxetine (Paxil) or citalopram (Celexa) or escitalopram (Lexapro) in depressed patients.
The purpose of this study is to learn if measures of brain chemicals from a brain scan called Magnetic Resonance Imaging and Spectroscopy (MRI/MRS) and brain activity (known as cortical excitability and inhibition) collected by Transcranial Magnetic Stimulation (TMS) are different in adolescents with depression who are in different stages of treatment. Researchers are conducting this study to learn more about how the brain works in adolescents with depression and without depression (healthy controls). This is important because it may identify a biological marker (a measure of how bad an illness is) for depression that could one day be used to identify depressed adolescents who would benefit from certain treatments (medications for example) or to monitor how well treatments are working.
This research study is being done to gain a better understanding about brain networks that may be involved in depression. The investigators plan to examine how these networks change after the brain is stimulated with "Transcranial Magnetic Stimulation" (TMS). TMS is a way of stimulating the brain in order to mildly activate or mildly suppress different brain areas, and is used to treat some forms of depression. It is hoped that this study will facilitate learning more about the structure and function of different brain areas and the ways that they are interconnected to form networks, both in depressed people and in people without depression. In this research study, the effects of TMS will be measured by obtaining "pictures" of the brain with "Magnetic Resonance Imaging" (MRI) and with "Positron Emission Tomography" (PET). More specifically, this will be accomplished with a combined MRI and PET scanner, which is capable of simultaneously obtaining both MRI and PET images of the brain. This scanning paradigm will allow the assessment of local metabolic changes resulting from TMS (with PET images) and brain network changes resulting from TMS (with fMRI). Changes resulting from TMS between 20 subjects with depression and 20 healthy volunteers will be calculated and will form the main outcome measure.
The purpose of this study is to evaluate the safety and efficacy of filorexant (MK-6096) versus placebo as adjunctive treatment for major depressive disorder (MDD), in participants who are partial responders to antidepressant monotherapy with one of identified selective serotonin reuptake inhibitors (SSRIs) or serotonin norepinephrine reuptake inhibitors (SNRIs), or bupropion. The primary hypothesis of the study is that filorexant is superior to placebo as augmentation therapy with respect to change from baseline to Week 6 in the Montgomery Asberg Depression Rating Scale (MADRS) total score.
