Active clinical trials for "Depression"

The purpose of this study is to evaluate the effects of Lu AA21004, once daily (QD), on cognitive dysfunction in patients with major depressive disorder.

Late Life Depression (LLD) is a serious health problem which not only causes depressed mood but also results in impairments in memory and attention. These impairments are likely to be resistant to treatment, which increases the chances of developing dementia even after successful treatment of mood.This study is a randomized controlled trial of transcranial Direct Current Stimulation (tDCS) in people with LLD to enhance their cognition after successful treatment of mood with established medications. tDCS is non invasive, relatively inexpensive and portable, and has been found to be safe.This study also serves as a pilot study to assess the effects of tDCS on cognition and neurophysiologic markers of cognition among patients with LLD. Primary study hypothesis is that participants Participants randomized to tDCS will perform better on a working memory task 2 weeks and 3 months following the tDCS course.

Transcranial magnetic stimulation (TMS) is an effective alternative for pharmacotherapy in major depressive disorder, but the effectiveness is not clear due to stimulated region, frequency and intensity of magnet field. Standard TMS techniques only can stimulate superficial cortical areas as the electric field decreases rapidly as a function of tissue depth，while depression is also interconnected with deeper neuronal regions. Deep-brain magnetic stimulation (DSM, or deep TMS, DTMS) allows stimulation of deeper cortical regions. Previous research has demonstrated that alpha frequency (8-13 Hz) EEG activity may have particular relevance to the response to antidepressants, and reduction of alpha frequency (8-13 Hz) could lead to negative symptoms. It has been reported that both alpha frequency and low-field magnetic stimulation could improve depressive symptoms. The objective of this study is to compare the effectiveness of the two different parameters of DMS in the treatment of major depressive disorder. The changes of brain derived neurotropic factor (BDNF) are also investigated to make a relevant analysis of the improvement of depressive symptoms.

Inositol hexaphosphate (IP6, also called inositol hexakisphosphate, and phytic acid) is a naturally occurring phosphorylated derivative of myo-inositol. Myo-inositol has shown preliminary evidence of efficacy in controlling mood symptoms, and good tolerability in bipolar disorder in some studies, but failed to establish efficacy in subsequent meta-analyses. In the investigators proposed work, the investigators plan to orally administer the calcium/magnesium salt of IP6 (2,000-3,000 mg daily in two divided doses) to paid research subjects with a diagnosis of bipolar disorder who are in a depressed state, and who have failed an adequate course of treatment with lithium monotherapy. The investigators hypothesis is that IP6 may be similar to myo-inositol in terms of relieving depression, but more potent and effective. Our aim is conduct a preliminary pilot study in 30 subjects (15 treated with IP6, 15 treated with lamotrigine, an active comparator) to assess the efficacy and tolerability of IP6 as an adjunctive treatment to lithium, the mood stabilizer most commonly used to treat bipolar disorder.

While there are many effective options for treating a major depressive episode, there are no clinical markers that predict the likelihood of remission with an initial trial of either an antidepressant medication or psychotherapy. The goal of this study is to test how brain function changes in depress patients treated with cognitive behavioral therapy (CBT) compared to patients treated with a selective serotonin reuptake inhibitor (SSRI, either escitalopram or sertraline), which are FDA approved antidepressants. The study aims to determine if bran scan findings might help physicians to select the most effective antidepressant treatment for an individual patient. Up to 100 male and female outpatients who are between 21-55 years old will be enrolled. Participation in the study will last from 14-26 weeks. Subjects will be randomized to receive either escitalopram (s-CIT) or CBT for 12 weeks. Resting-state positron emission tomography (PET) and BOLD functional magnetic resonance imaging (fMRI) scans will be done before the treatment begins, and again at the end of treatment (week 12). Non-responders to s-cIT or CBT will be crossed over to receive an additional 12 weeks of treatment with the alternative intervention.

The purpose of this study is to evaluate the effects of a single low dose of the D2/D3 antagonist amisulpride on reward processing. More generally, this study will test the role of dopamine (a naturally occurring brain chemical) in depression. Hypotheses: Administration of a single low dose of the D2/D3 antagonist amisulpride will (1) improve performance in a behavioral task assessing learning from feedback and (2) boost activation in reward-related brain regions.

The purpose of this study is to assess the safety and efficacy of Lu AA21004 in participants with major depressive disorder after completion of an 8-week double-blind treatment period in a preceding study (Lu AA21004/CCT-003; NCT01355081).

The purpose of this study is to determine if CX157 is effective and safe in patients with treatment of treatment resistant depression over six weeks of treatment.

The purpose of this study is to see if creatine, which is a naturally occurring chemical in the body, is effective for treating Major Depressive Disorder (MDD) in female teenagers. The primary hypothesis is that compared to placebo, 2g, 4g, and 10g of creatine monohydrate for eight weeks will be associated with a significant increase in brain phosphocreatine (PCr) concentrations.

Duke University Medical Center in collaboration with Glendale Adventist Medical Center propose a randomized clinical trial of conventional cognitive behavior therapy (CCBT) vs. religious cognitive behavior therapy (RCBT) for major depression in medical patients with chronic disabling illness. Therapists will deliver the treatment in real time over the Internet and/or by telephone to increase treatment access. This planning grant seeks support for a two-site study (North Carolina and California) that consists of two phases. In Phase I (Rounsaville 1a) the investigators will conduct an open trial of 30 patients to assess subject recruitment, refine RCBT and CCBT manuals and protocol, assess compliance with treatment, acceptability of treatment and delivery system (online vs. telephone), and allow therapists gain experience with delivery system and RCBT. In Phase II (Rounsaville 1b) the investigators will conduct a randomized proof of concept comparison of CCBT vs. RCBT that will demonstrate feasibility and confirm the expected clinically meaningful difference for a definitive R01 application. In Phase II, 70 religious patients ages 18-85 with a new episode of major depression (MINI), scores of 16-35 on the Beck Depression Inventory (BDI), and at least one chronic disabling medical illness will be randomized to either CCBT or RCBT. The trial will consist of ten 50 min sessions administered by master's level therapists and delivered over 12 weeks. The primary endpoint will be BDI score at baseline, 4, 8, 12, and 24-week follow-up. Christian, Jewish, Hindu, Buddhist, and Muslim versions of the RCBT manual will be developed, and CBT experts in each of these traditions will supervise therapists delivering the intervention to patients from these faith traditions. The purpose of this study is to determine feasibility and effect sizes for a future, fully powered treatment study. The importance is that results will be relevant to therapists well beyond those who explicitly practice pastoral counseling, extending to many secular therapists as well. If 65% of Americans indicate that religion is an important part of daily life and the vast majority of chronically ill medical patients wish to include it in their therapy, then all therapists (whether they have explicit training in pastoral counseling or not) are likely to encounter patients in which this approach would be applicable.
