View clinical trials related to Depressive Disorder, Major.
Filter by:This is an open label, randomized, add-on, 8 weeks multicentre study to evaluate the efficacy and safety of paroxetine Controlled Release (CR) in patients with Major Depressive Disorder (MDD) comorbid Irritable Bowel Syndrome (IBS). Subjects will be patients who are referred to the outpatient or inpatient clinic of gastroenterology departments of province level general hospitals in China. All subjects present with irritable bowel syndrome according to ROME III, and also are diagnosed with MDD by Mini-International Neuropsychiatric Interview (MINI). All subjects will provide written informed consent prior to participating in the study. Subjects will be assessed for eligibility at a screening visit, with eligible patients returning for a assessment within 1 week, at which time they will randomly enter into paroxetine CR (12.5mg/d, flexible dose: 12.5-50mg/d) plus IBS regular treatment or IBS regular treatment only. Subjects will be evaluated at weeks 2 (Day 14), 4 (Day 28), 6 (Day 42) and 8 (Day 56), for a total of 5 study treatment visits.
The primary objective of this study is to evaluate the safety and efficacy of an electronic cognitive behavioral therapy application (eCBT Mood) compared to a control group consisting of a mood monitoring handheld computer application in the treatment of patients with mild to moderate major depressive disorder.
The purpose of the study is to explore the efficacy of 6 weeks treatment of an investigational medication, RO4995819, versus placebo as adjunctive therapy in patients with major depression.
Ketamine infusions resulted in an acute reduction in global depression scores and in severity of suicidal ideation. Scopolamine infusions produced also a significant improvement in depression that was sustained over time. We therefore plan to investigate the feasibility and efficacy of open-label repeated intravenous administration of ketamine and scopolamine combined in this population of severely depressed, treatment-resistant patients. The results from this study could lead to the development of new strategies for the treatment of patients with TRD.
The pilot study will evaluate whether electronic-Measurement Based Care (e-MBC) using the UT Southwestern MyChart personal health record is feasible, associated with patient and health care team satisfaction, and improves treatment outcomes compared to a standard treatment model. The project will be conducted in the Simmons Cancer Center Clinic at the University of Texas Southwestern Medical Center, Dallas as a collaborative effort between the Departments of Psychiatry, Oncology, and Family and Community Medicine. The primary patient population will include adults with significant depression and/or starting an antidepressant treatment and/or experiencing a treatment change. The study will compare two groups, an e-MBC group and an office-based standard care MBC group. Study staff will explain the study to the patients, specifically explaining that study participants will receive either office-based MBC or e-MBC. Eligible participants must be willing to receive either form of treatment monitoring. Participating patients will be randomly assigned to receive either e-MBC or office-based MBC. In the e-MBC group once a month the study nurse will send a prompt from the participating patients treating physician requesting the patient to use the MyChart system to fill-out the MBC scales. Beyond these monthly assessments, patients will be encouraged to utilize the MyChart MBC assessments (e-MBC) at any time to communicate with their physician. Patients experiencing difficulties using the e-MBC system will be given additional instruction by the study nurse. Patients and physicians will be trained in the use of the eMBC system. In the office-based MBC group the study nurse will schedule monthly treatment visits and request the patient call as needed to report symptoms. The evaluation period will be 6 months.
Background: - Antidepressants help many people with depression, however, some do not seem to benefit as much. Currently, it is not possible to determine who will improve with certain antidepressants. Studies have shown that genes may influence whether an antidepressant works for an individual. Other studies have shown that depressed people tend to have lower levels of a chemical called glutamate in parts of their brain, and that glutamate levels increase after recovering from depression. Researchers want to study the antidepressant citalopram (Celexa) to see how it affects glutamate levels in the brain. They also want to study how a person s genes affect their response to this treatment. Objectives: - To see whether glutamate levels and certain genes affect how a person responds to a particular antidepressant medication. Eligibility: - Individuals between 25 and 55 years of age who have been diagnosed with major depression (without psychotic features). Participants may not have tried more than three antidepressant treatments. Design: - Participants will be screened with a physical exam and medical history. They will answer questions about mood and current feelings of depression, as well as family history of depression. Blood and urine samples will be collected. - This study will have two phases. The first phase may last up to 7 weeks depending on current antidepressant use and involves one to seven outpatient visits. The second phase lasts 8 weeks and involves five outpatient visits, one every 2 weeks. - In the first phase, participants will stop taking their current antidepressant medications for at least 2 weeks before the next phase of the study. Participants who are on fluoxetine (Prozac) will need to be off it for 6 weeks. - At the end of this phase, participants will have brain imaging studies to look at brain function and chemistry. - In the second phase, participants will take citalopram at the standard dose. They will answer questions about mood and response to the medication. They will also provide blood and saliva samples for tests. - At the end of this phase, participants will have brain imaging studies to look at brain function and chemistry.
The investigators propose a test of causality by examining a cohort of patients undergoing deep brain stimulation (DBS) within the ventral striatum. The investigators will examine behavior on and off stimulation across a range of tasks that index different forms of impulsivity. Patients will be studied in both the ON and OFF state - that is, they will be tested during active deep brain stimulation and 30 min to 1 hour after stimulation has been stopped (order of state will be counterbalanced across subjects). The investigators specific aim is to test the hypothesis that enhancing ventral striatal signaling (i.e. ON-state DBS) will cause more impulsive patterns of behavior across several impulsivity tasks. The investigators predict that ventral striatal DBS will increase stop-signal reaction time on the stop-signal task and commission errors on the Go/NoGo task, and increase delay aversion in a delay discounting paradigm.
The purpose of this study is to examine the potential impact of the assay in terms of depression severity as measured by change in Clinical Global Impressions (CGI) scale at 3 months.
Lurasidone HCl is a compound that is a candidate for the treatment of major depressive with mixed features.This clinical study is designed to test how well Lurasidone works to treat major depressive disorder with mixed features.
Background: - Medications to treat major depression act on a brain chemical called serotonin, which binds to receptors on brain cells. More research is needed on how serotonin receptors work in the brain, and imaging studies such as magnetic resonance imaging (MRI) can provide information on how these receptors function in the brains of individuals with depression and healthy volunteers. The experimental radioactive chemical [11C]CUMI has been designed to react with serotonin receptors, and researchers are interested in studying its effectiveness using positron emission tomography (PET) scanning to see how well it gets into the brain. Objectives: - To evaluate the effectiveness of the radiotracer [11C]CUMI in brain imaging studies of serotonin receptors. Eligibility: - Individuals between 18 and 55 years of age who either have been diagnosed with major depressive disorder or are healthy volunteers. Design: - Participants will be screened with a full medical history, physical and psychiatric examination, blood and urine tests, and questionnaires about mood. Participants will also have an electrocardiogram at this visit. - At the first study visit, participants will have a MRI scan of the brain to provide baseline data on brain function. - At the second study visit, participants will have a PET scan with the [11C]CUMI contrast agent. - No treatment will be provided as part of this protocol....
