Filter by:Developing more effective and faster acting antidepressant is of outmost clinical importance. Available antidepressant therapies have a delayed therapeutic effect. It typically takes several weeks before symptom relief is evident. Furthermore, antidepressants are relatively ineffective - as many as 30% of patients do not respond to any medication at all. In this study the investigators evaluate the NMDA-receptor antagonist ketamine as a potentially new antidepressant treatment for severely depressed patients and compare its effectiveness with that of electroconvulsive therapy (ECT).
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.

This study will investigate the biological pathways involved in anti-depressant resistance that increase risk of cardiovascular disease in people with depression.
The primary purpose of this study is to examine how much change in depressive symptoms will be observed in persons who use an electronic Problem Solving Treatment (imbPST) compared to a control group at pre-, mid-point, and post-test assessments.
Depression (major depressive disorder; MDD) is a very common mental disorder. Research suggests that individuals with prior depressive episodes have a risk of the relapse or recurrence of MDD. Secondary prevention has been identified as a key goal in the long-term management of the disease. The current project aims to investigate whether group based Acceptance and Commitment Therapy (ACT) can reduce surrogate and clinical markers of relapse in a group highly vulnerable to depressive episodes. The group intervention will consist of eight sessions, and each group will consist of maximum 12 persons. The project also studies whether Attention Bias Modification (ABM) preceding the ACT intervention will enhance the effect. ABM will be administered over a fourteen days period prior to the ACT-intervention. Effect will be measured over a period of 12 months. The primary outcome is changes in depressive symptoms. ACT-specific secondary outcome measures are also included. Subjects with a history of major depression (n=200), currently in remission, will be recruited from Sørlandet Hospital (100 participants). Matched participants (100 participants) will be recruited at the University of Oslo. In the first phase, participants from Sørlandet hospital will be randomized to ABM treatment or control condition. In the second phase all participants from Sørlandet hospital will receive group based ACT treatment. Group based ACT and ABM represent interventions that are time and cost effective, and that could be made available to large number of individuals struggling with MDD.
The Thinking Healthy Program is evidence based psychological intervention, delivered by non-specialists, with proven impact on maternal depression. A major challenge in the scale-up of this intervention, especially where health systems are weak, is providing quality training and supervision at scale. Women living in post-conflict areas are at a higher risk of depression than the general population.The key innovation proposed is the development and evaluation of a technology-assisted cascade training and supervision system to assist scale-up of the Thinking Healthy Programme in a post conflict area of Pakistan.
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.
An 8-week, assessor-blind, randomized controlled trial will be conducted. A total of 138 patients with post-stroke depression (PSD) will be randomly assigned to the combination acupuncture treatment (CAI) (n = 69) or least acupuncture stimulation (LAS) (n = 69) for 3 sessions per week for 8 weeks. Treatment outcomes will be measured using the 17-item Hamilton Self-Rating Depression Scale (HAMD-17), the Montgomery-Asberg Depression Rating Scale (MADRS), and Self-Rating Depression Scale (SDS) for depression symptoms; Barthel Index (BI) for physical function, the Montreal Cognitive Assessment (MoCA) for cognitive performance. The assessment will be performed at baseline and once monthly thereafter. The study will be conducted in School of Chinese Medicine Clinics, Tung Wah Hospital, Kowloon Hospital.
Transcranial Magnetic Stimulation (TMS) is an increasingly accepted neurostimulation- based treatment for major depressive disorder. While there is a growing anecdotal database supporting its use in bipolar depression the investigators propose to collect open label efficacy and safety data in a small population of patients with clinically verified bipolar disorder.
