Filter by:Depression (Major Depressive Disorder; MDD) has been dubbed "the common cold among the mental illnesses" and it is also a highly recurrent disorder. Secondary prevention has been identified as a key goal in the long-term management of depression. High recurrence rate suggests that there are specific vulnerability factors that increase people's risk for developing repeated episodes of the disorder. Preventive strategies should identify and ameliorate these factors to reduce the individual's risk of subsequent episodes. Biased attention for emotional stimuli is central to the cognitive model where increased sensitivity to negative cues is believed to fuel the negative thoughts and feelings in depression and play a key role in maintaining the illness. Selective biases in attention can be modified by a simple computerized technique; The Attention Bias Modification Task (ABM). This project aims to investigate whether ABM can reduce surrogate and clinical markers of relapse in a large group highly vulnerable to depressive episodes. The effects of ABM, immediately after the two weeks intervention, on three key risk factors for depression will be studied: Residual symptoms, cortisol awakening response and emotion regulation strategies. The participants will be followed up after 1 month, 6 months and 12 months. The hypothesis that ABM will reduce subsequent episodes of low mood over the following 12 months in this group in a manner predicted by early changes in these risk factors will be investigated. It will also be tested if such effects in the lab may be dependent on candidate genes which affect serotonin reuptake and which have been implicated in malleability and emotional learning. Effects on underlying neural correlates of emotion regulation will be studied in an fMRI experiment in a sub-sample and which will also be stratified by serotonin transporter genotype (see also NCT02931487). The predictive value of meta cognitions related to rumination and the possible mediating effects of automatic thoughts and perceived stress will also be investigated in a sub group (see also NCT02648165). The characterization of the cognitive, genetic and neural mechanisms underlying the ABM effect will have key implications for future treatment development and combination with other treatment modalities like pharmacotherapy.

Acquiring, processing and utilising "information" is crucial to any mental function -including seemingly simple daily functions. Collectively called 'cognitive functions', these processes are a result of different regions of the brain acting together. Disruption of these cognitive functions increases the risk of development of mental health problem. Recently it has been proposed that inflammatory pathways may contribute to disorders of cognition and behaviour like depression. This is largely due to research showing that those with inflammatory conditions like arthritis are more likely to develop mental health problems like depression. Conversely, those who suffer from mental health problems (even in the absence of inflammatory conditions) have large amounts of inflammatory molecules in the blood. Studies in animals suggest that inflammation outside the brain can reach and affect the brain in a number of ways. So, does inflammation play a role in the development of cognitive and behavioural symptoms? What are the pathways involved? The current project tries to address this question. Specifically, the investigators intend to use modern scanning techniques to examine the effect of inducing a low grade inflammation (using a commonly used typhoid vaccine) to see how the inflammation affects how different regions of the act together to perform cognitive functions.
Recent reports have shown that alcohol misuse is a particularly serious problem among the 18 to 25 year old age group. Previous medication trials with SSRI antidepressants among young adults with co-occurring depressive disorders, including our own recent trials with SSRI medications, have produced disappointing results, especially for decreasing the level of alcohol consumption. Mirtazapine is a non-SSRI medication with a unique structure and mechanism of action. Recent study results suggest that mirtazapine is more effective than other antidepressants for treating non-comorbid depression. A few recent studies with mirtazapine have been conducted among subjects with comorbid AUD/MDD, and those studies have demonstrated efficacy for mirtazapine for decreasing the depressive symptoms and the alcohol craving of subjects with comorbid AUD/MDD. However, those studies did not measure level of alcohol consumption, so it is unclear whether mirtazapine decreases the level of alcohol use of that comorbid population. The results of our own very recent open label pilot study suggest robust within-group efficacy for mirtazapine for decreasing both the level of alcohol use and the depressive symptoms of comorbid subjects. However, that pilot study did not include a placebo control group, so the efficacy of mirtazapine versus placebo for decreasing the level of alcohol use among persons with comorbid AUD/MDD remains unclear. This grant submission proposes to conduct a first double-blind, placebo-controlled pilot study to provide a preliminary assessment of the efficacy of mirtazapine versus placebo for decreasing both the alcohol use and depressive symptoms of young adults with comorbid AUD/MDD. If results (effect sizes) from the proposed study are found to be promising concerning outcome differences between the mirtazapine and placebo groups, then we will use those findings to apply for an R01 study to definitively assess the efficacy of mirtazapine for treating young adults with AUD/MDD.
The current study wishes to contribute to the applicability of the use of ketamine in a clinical setting by focusing on the efficacy of intra-nasal administration compared with the IV route.
The purpose of this antidepressant study is to determine the efficacy of vortioxetine on depression and cognition in 80 women with breast cancer, and to elucidate inflammatory-mediated mechanisms by which depression and its treatment influence cancer outcome. Our hypothesis is that effective vortioxetine antidepressant therapy in depressed women with breast cancer will attenuate increased intermediate endpoints of inflammation that contribute to the pathogenesis of depression, cognitive impairment, and cancer progression
In this randomized clinical trial, subjects will be assigned to either an assay-guided treatment condition (AGT) or a treatment-as-usual condition (TAU). All subjects will provide a DNA sample at the Screening Visit for the Genecept Assay ™. In the AGT condition, assay results will be provided to the treating investigator, who will use the results to guide antidepressant pharmacotherapy. In the TAU condition, the investigator will treat the subjects without the knowledge of the pharmacogenetic testing results. Assay results for all subjects will be provided to the investigator once all Week 8 visit procedures have been completed. Raters of the primary endpoint assessment and subjects will remain blinded to treatment assignment.
The study will investigate whether cognitive behavioral psychotherapy (CBT) combined with prefrontal transcranial direct current stimulation (tDCS) is more efficacious with regard to symptom reduction in depressed patients than CBT combined with sham-tDCS or CBT alone.
Major Depressive Disorder (MDD) is a mood disorder, highly prevalent in Brazil and in world. The treatments of choice are the psychotropic drugs of the class of antidepressants and Behavioral or Cognitive Behavior Therapy (CBT). The aim of this study is to compare the efficacy of Trial Based Cognitive Therapy with the Behavioral Activation and pharmacotherapy in the treatment of MDD in a randomized clinical trial witch 96 patients with MDD,
This study aims to analyze the effectiveness and feasibility of using an implantable system that provides epidural electrical stimulation directly to the left prefrontal dorsolateral cortex (Brodmann area 9/46) in patients with chronic and refractory Depressive Disorder Major.
