Filter by:In this study, the investigators test whether a 4-week 12-session attention bias modification treatment (ABMT) could reduce depressive symptoms relative to placebo controls in young adults with major depressive disorder at post-training and 3-month follow-ups. Meanwhile, the investigators also test whether a 2-week 4-session ABMT booster training for every three months could reduce residual depressive symptoms and recurrences relative to placebo controls for 1-year follow-up
To evaluate the efficacy and safety of adjunctive pimavanserin compared to placebo in subjects with major depressive disorder who have an inadequate response to antidepressant therapy
The purpose of the study is to determine the efficacy, safety and pharmacokinetics of inhaled Esketamine in participants with treatment-resistant depression (TRD) in the course of Major Depressive Disorder (MDD). The study is to determine the efficacy and dose response of three Esketamine doses, compared with placebo.
People experiencing severe mental illnesses (SMI), including schizophrenia, psychosis, bipolar disorder and major depressive disorder, are prone to poorer physical health and increased incidences of premature mortality when compared to the general population (De Hert et al., 2009; Hert et al., 2011; Hennekens et al., 2005; Tiihonen et al., 2009 . High-intensity-interval-training (HIIT) is a type of exercise involving alternating short bursts of high intensity exercise with recovery periods of rest/ light exercise (Weston, Wisløff & Coombes, 2014). HIIT improves physical health, quality of life and cognition in the general population and in those with physical health disorders (Gomes-Neto et al., 2017; Hwang, Wu & Chou, 2011; Wen et al., 2019). It has been proposed that HIIT may improve symptoms, physical health and time to discharge among inpatients with SMI. The research will involve three stages: 1) Focus groups, 2) A pilot study, 3) Follow-up qualitative interviews and focus groups. Firstly, a series of focus groups with inpatients with SMI, carers of individuals with SMI and clinical staff will be conducted. The focus groups will scope perceptions of attitudes, and practicalities of a pilot RCT. The information gained will be used to inform a pilot HIIT trial which will evaluate whether HIIT is acceptable and feasible amongst this population group. Each focus group will run for ≈2 hours and will involve an open discussion about the benefits and barriers of conducting HIIT exercise sessions in a population with SMI. Secondly, the HIIT pilot study will be trialed. The final protocol will be developed with feedback from the focus group but will involve an RCT where 12 weeks of HIIT will be compared to 12 weeks of treatment-as-usual (TAU). HIIT will be conducted, twice a week, in a supervised environment using a stationary bike. Inpatients with a diagnosis of SMI will be eligible to participate. Thirdly, follow-up qualitative interviews, with pilot study participants, those that withdrew and those that did not want to take part, and focus groups with clinical staff will address the acceptability and feasibility of HIIT.
Major depression (MD) is common during adolescence and associated with significant morbidity and mortality. One important factor for the development and maintenance of adolescent MD are disturbances in emotion regulation, including deficits in cognitive reappraisal (CR). CR is a particularly effective emotion regulation strategy that aims at reinterpreting emotional events to modify affective responses. Adolescents with MD apply this strategy less often than their healthy peers and show disturbances in brain activation patterns underlying CR. In this study, MD adolescents will be randomly assigned to a group that receives a task-based training in CR or to a control training group. It will be examined whether the task-based CR training is superior to the control training with regard to improvements in negative affect, perceived stress in daily life and depressive symptoms. Moreover, during the four training sessions, the event-related potential "Late Positive Potential" (LPP) will be recorded to assess neurophysiological indices of CR processes and gaze fixations on emotional areas within negative pictures and affective responses to pictures will be collected to identify mechanisms underlying training effects.This study will provide first evidence for the efficacy of a short-time training that has previously shown to be effective in healthy individuals. Moreover, the study will identify neurobiological mechanisms that predict training effects. The results of this investigation will lay the ground for a clinical trial to investigate whether a CR training added to an established intervention improves treatment effects for adolescent MD.
Transcranial magnetic stimulation (rTMS) is an approved treatment for depression. The purpose of this study is to test an adjunctive medication, D-cycloserine, in rTMS for depression using a placebo-controlled design. D-Cycloserine is a partial N-Methyl-D-Aspartate receptor (NMDAr) agonist, and therefore may enhance the effects of rTMS, however there is data to support and refute this hypothesis. Using a double-blind design, the investigators will randomize patients with Major Depressive Disorder to receive either daily low dose D-cycloserine or placebo in conjunction with rTMS to the left dorsolateral prefrontal cortex. After 10 treatments (2 weeks), this double-blind period will conclude and all participants will receive an additional 10 treatments (2 weeks) of rTMS without any adjuncts. The primary outcome will be improvement in clinician rated depressive symptoms at the conclusion of the study.
This study aims at investigating the persistence of antidepressant effect of Nitrous Oxide (N2O) for Treatment-Resistant Depression(TRD). The investigators also aim to assess the effect of N2O on the electroencephalograph, multimodal magnetic resonance imaging(MRI), blood cytokines, feces bacteria flora and neuropsychological performance in patients with TRD. The investigators further aim to identify the predictors of N2O's antidepressant effeect using the above techniques.
The antidepressant medications are among the most commonly prescribed pharmacological agents in patients with mood and anxiety disorder. Despite recent advances in antidepressant pharmacotherapy, there is a pressing need for substantial optimization and improvment of outcome of pharmacotherapy of psychiatric disorders by providing individualized and science-based treatment guidelines. Besides it is rather difficult in clinical practice to predict, which patient will response to a certain pharmacological treatment well and which one less so. Putative predictors of response to antidepressant include demographic and clinical characteristics, personality traits, biological markers and psychophysiological features. Recently the research studies shown that divergences in antidepressant efficacy may be related to genetic variations of patients. The pharmacogenetic studies have multiplied in recent decade due to the impact that such studies may have in everyday clinical practice once reliable predictors could be identified. The pharmacogenetic research using new DNA microarray-based technology can reasonably be expected to contribute to the prediction of likelihood of treatment response and risk of development of adverse side effects in individual patients in case of antidepressant treatment. By reducing costly treatment failures and the likelihood of serious adverse events, pharmacogenetic testing may help to improve the treatment possibilities for chronic diseases, reduce the burden prescription drug costs, and lower the costs of drug development. The further detailed investigation of peripheral gene expression profiles may help to identify responsible genes that underlie the process of development of affective disorders and open novel horizons for understanding molecular mechanisms of psychopharmacological treatment.
The objective of this study is to determine the effect of music therapy during dialysis on: depression, anxiety, quality of life, blood pressure, heart rate, medication compliance, compliance with dialysis treatment, number of hospitalizations, pain level, and energy level.
The purpose of this study is to pilot a primary-care based mindfulness intervention for chronically traumatized African Americans screening positive for posttraumatic stress disorder (PTSD) and major depressive disorder (MDD) in primary care clinics within an urban public hospital. The study will utilize a randomized controlled trial (RCT) design along with a multi-method psychological and physiological assessment approach to establish the feasibility and acceptability of a mindfulness-based cognitive therapy (MBCT) intervention for primary care versus wait-list control in African Americans with chronic trauma exposure and comorbid PTSD and MDD. Preliminary mechanisms of action associated with MBCT including emotion dysregulation and autonomic function will be evaluated. The data collection and 8-session group intervention will take place in primary care clinics within an urban public hospital serving primarily low-income, minority individuals (>80% African American).
