Active clinical trials for "Depressive Disorder"

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 primary objective of this study is to test in a randomized controlled trial if aftercare-coordination by phone subsequent to inpatient treatment is an effective aftercare approach in the treatment of depression and anxiety.

This randomized effectiveness trial evaluates a quality improvement intervention aimed at providing access to evidence-based depression treatments (particularly cognitive-behavior therapy for depression and or pharmacotherapy) through primary care for youth ages 13-21, as compared to enhanced usual care. The major hypothesis is that the quality improvement intervention will be associated with improved outcomes, relative to enhanced usual care.

The aim is to evaluate the effects of Internet based Stepped Care on anxiety, depression and health related quality of life in cancer patients with anxiety and depression symptoms, compared to Standard Care, and to evaluate the health-economic effects of the intervention. The investigators also want to examine the development of anxiety and depression symptoms and health related quality of life in cancer patients without initial symptoms. The primary hypothesis is that Internet based Stepped Care (I-SC) is more effective in relieving anxiety and depression symptoms in cancer patients, compared to Standard Care (SC). Secondary hypotheses are that less anxiety and depression symptoms also means improved health related quality of life and that I SC is cost-effective or at least cost neutral compared to standard care. The IT-platform Carebase.se is developed within U-CARE. The platform will be used for delivering of interventions and for collection of all patient reported outcomes. Patients with anxiety or depression symptoms according to the Hospital Anxiety and Depression Scale will be randomized to I SC or SC. Patients with no initial anxiety or depression symptoms will be included in descriptive studies. All patients, in the randomized controlled trial and the descriptive study will followed up during 24 months I-SC comprises interactive support (Step 1) and Cognitive Behavioral Therapy (CBT; Step 2). Step 1 starts directly after randomization and extends over a 24 months period. Step one comprises web-based patient education including psycho-education and easy interventions strategies employed in CBT. Step 1 also includes a FAQ, a discussion board for patients and a personal diary. Project staff (nurses) is responsible for the FAQ and to moderate the discussion board. The nurses will be supervised by a CBT psychologist. They can also turn to other experts in the project group for advices about how to answer patients' questions. Patients with remaining anxiety or depression symptoms at 1, 4 or 7 months after randomization will be offered Step 2. Step 2 comprise conventional Internet based CBT for common psychological concerns. The participants' chooses to work with modules that correspond to prioritized concerns, e.g. anxiety or depression. The CBT is structured and manualized and include conventional treatment methods with homework and weekly contacts with the psychologist. Step 2 extends over a 10-week period.

This study evaluates the feasibility of the Groups for Health (G4H) intervention for adults accessing support for depression in the UK. G4H targets improvements in adults' interpersonal functioning in order to reduce feelings of loneliness. The study will adapt the G4H intervention for delivery to adults seeking treatment for depression in the UK and estimate trial parameters (recruitment, retention, missing data and acceptability) of the adapted intervention, prior to a definitive trial. A mixed methods design of interviews and a single group, pre-post study will be employed.

This study will investigate whether administration of a single dose of the serotonin receptor subtype 4 (5-HT4) partial agonist prucalopride has effects on emotional processing and non-emotional cognition in healthy volunteers, compared to placebo administration. Using an experimental medicine approach, the effects of prucalopride on cognitive biomarkers of antidepressant action will be characterised. In a double-blind design, participants will be randomised to receive a single dose of either prucalopride (1mg) or placebo. All participants will come for a Screening Visit to ensure their suitability for the study. If they meet study criteria, they will be invited to a Research Visit, where they will receive the study medication and wait for two hours while the drug reaches peak levels. After two hours they will be asked to complete a series of computer-based tasks measuring emotional, non-emotional cognitive processing, and reward processing. The primary study hypothesis is that acute prucalopride administration will have positive effects on processing facial expressions of emotion. Secondary hypotheses are that acute prucalopride administration will affect other measures of emotional processing, and non-emotional cognition.

This is a randomized controlled trial to evaluate the community-based effectiveness of virtual reality job interview training (VR-JIT). Northwestern University is partnering with Thresholds Inc. to evaluate the effectiveness of VR-JIT at improving interviewing skills and access to employment. In addition, we will evaluate the cost effectiveness of VR-JIT and the process for implementing VR-JIT at Thresholds.

The steroid hormone cortisol is released in response to stress and acts in the central nervous system upon glucocorticoid (GR) and mineralocorticoid receptors (MR). GR are widely distributed across the brain while MR are predominantly expressed in the hippocampus and prefrontal cortex - two brain areas closely related to memory and executive function. Stimulation of MR leads to an increase of glutamate that act on glutamatergic NMDA receptors in the hippocampus and prefrontal cortex. In previous studies, the investigators have shown that fludrocortisone, a mineralocorticoid receptor (MR) agonist, improves memory and executive function in depressed patients and healthy controls. However, depressed patients not only exhibit cognitive deficits in traditional neuropsychological domains such as memory or executive function. In addition, there are depression-specific alterations such as cognitive bias and deficits in social cognition, two clinically highly relevant areas. Therefore, the specific aims of this renewal proposal are two-fold: To examine whether beneficial effects of fludrocortisone in depressed patients can be extended to depression-specific cognitive bias and to social cognition To determine whether beneficial effects of fludrocortisone depend on NMDA-receptor function and whether these beneficial effects can be enhanced by NMDA receptor stimulation. The investigators hypothesize that fludrocortisone will improve cognitive bias and social cognition in depressed patients and that its beneficial effects depend on the NMDA receptor. Therefore, the investigators further hypothesize that the effects of fludrocortisone can be enhanced by co-administration of the partial NMDA receptor agonist D-cycloserine. The study not only advances current knowledge by further examining the mechanism of action by which MR stimulation exerts beneficial effects on cognition but extends these effects to depression-specific cognitive bias and alterations in social cognition. Furthermore, a potential interaction between MR and NMDA receptors is highly clinically relevant given the promising results with NMDA receptor antagonists in the treatment of major depression.

Depression is a common perinatal complication that can have a profound, adverse effect on maternal and child health outcomes. The proposed study will directly address this important, but understudied area by evaluating the feasibility and preliminary effect of an innovative, integrated intervention approach, BEST-maCARE [Better Education, Support, Treatment for maternal Capacity, Adherence, REtention in care]. The multi-component intervention is guided by a model drawn from self-regulation and bioecological systems theory. Proactive counseling personalized to the patient and socio-cultural context is delivered by trained clinic personnel (e.g., counselors) to build problem solving and coping skills and linkages to mental health, HIV treatment and ancillary services. The theory-guided intervention approach has been found effective in improving the health behavior and outcomes (e.g., virologic) of vulnerable, marginalized HIV+ women and men in rural and urban settings in the US (AI38858-ACTG 731; R01NR05108). Although the investigators formative research suggests that it is well suited for the target population, its usefulness in addressing significant gaps in care among perinatal women. l women with co-morbid conditions in a different socio-cultural, limited resource setting has not been studied.

The aim of this study was to investigate the effects of duloxetine on improvement of brain cortical activity in patients suffering from major depressive disorder using near infrared spectroscopy.
