Filter by:This study is dedicated to achieving a better understanding of how the brain processes information. Specifically, the investigators are studying cognitive function, thought process, and impulsivity in people with and without suicidal thoughts. You are being asked to participate in a research study to learn how the use of a medication, risperidone, improves your symptoms of depression. Specifically the investigators are studying the effectiveness of reducing the thought of suicide and other symptoms of severe depression. Risperidone is approved by FDA for the treatment of schizophrenia and bipolar mania, and clinical practice suggests that it might benefit patients with major depressive disorder. During clinical trials with 2607 patients, risperidone was proved to be safe. This is a pilot study to test a new indication of risperidone for treatment of severe depression. The study medication will be given in addition to usual psychiatric care.
This study is looking at the safety and efficacy of combined ketamine and lithium therapy for treating patients with bipolar depression who are taking a mood stabilizer that is not working for them.
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 long-term goal is to determine if decreased blood flow to the brain (cerebral hypoperfusion) is predictive of antidepressant outcomes in late-life depression (LLD). Studies in younger adult report that successful antidepressant treatment is associated with increases in cerebral blood flow, with no change in blood flow being observed in nonresponders. Thus cerebral hypoperfusion may be a biomarker of poor response to antidepressants. In LLD, this may occur secondarily to underlying vascular disease. If LLD is characterized by cerebral hypoperfusion and it does have predictive power to identify individuals who will poorly respond to conventional antidepressants, this would support the study of interventions that improve cerebral perfusion and may improve antidepressant outcomes. As an initial step in this research, this pilot study will utilize MRI to examine if resting blood flow deficits predict and persist with antidepressant nonremission in an elderly population. The rationale for this proposal is that it will guide the design and power requirements of a larger, definitive trial examining the relationship between cerebral perfusion and depression outcomes. Importantly, support for this mechanism being linked to LLD would also support studies examining the antidepressant efficacy of drugs that may improve cerebral perfusion. The primary purpose of this pilot study is a) to demonstrate feasibility by recruiting, scanning, and treating depressed elders; and b) to acquire preliminary data for competitive grant submissions. SPECIFIC AIM: To use MRI to test for differences in cerebral perfusion between individuals who do and do not remit to a 8-week course of sertraline.
Electroconvulsive therapy (ECT) has unparalleled efficacy in treating severe depression that is resistant to common modalities of treatment, such as antidepressant medication. Although treatment with ECT has benefited many individuals with treatment resistant depression (rates as high as 50-75%), its more widespread use is hindered by the social stigma associated with the treatment, as well as by its significant cognitive side effects. Moreover, ECT cannot be precisely targeted, since it produces a widespread activation of the brain surface, in turn, affecting many different functional areas. Magnetic seizure therapy (MST) is currently being investigated as an alternative to ECT, as it is more focused to one area of the brain. Rather than applying electrical stimuli to induce a seizure, as is done in ECT, MST uses repetitive magnetic stimulation to produce the seizure. Preliminary research suggests that MST can result in therapeutic effects comparable to those produced by ECT, but without the negative side effects on cognition. The proposed study is a randomized, controlled trial, in which the efficacy and side effect profile of MST will be compared to those of ECT. If successful, the results of this study may lead to increased treatment availability and accessibility, as well as lessen the substantial health care costs associated with treatment resistant depression.
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.
This proposed research is aimed to investigate the efficacy and safety of combined cytidine- and creatine-containing drug and dietary supplement in treating bipolar depression and to evaluate changes in relevant brain biochemical metabolism using magnetic resonance spectroscopy.
