Filter by:Repetitive Transcranial Magnetic Stimulation (rTMS) is a promising, novel, non-invasive therapy for depression. The study is looking at changes in specific electroencephalogram parameters in depressed patients treated with rTMS can serve as predictors of depression treatment response among cancer patents undergoing rTMS treatment of depression.
Traumatic brain injury (TBI) is a major public health problem with an annual incidence of about 1.7 million per year. TBI is associated with various long-term morbidities. Among them, psychiatric disturbances are the major cause of chronic disability and poor quality of life. Major depression is the common psychiatric sequela post TBI with rates ranging from 13% at 1 year to 60% at 8 years after TBI. Major depression after TBI (henceforth referred to as TBI depression) is often associated with comorbid neuropsychiatric symptoms (NPS) such as anxiety, aggression, substance abuse and cognitive deficits that often makes treatment difficult. Despite increased rates of depression, there is no Food and Drug Administration (FDA) approved drug/s for its treatment. The investigators propose to address these limitations by use of a novel serotonergic agent, vortioxetine, which has a multimodal mechanism of action through serotonin transporter (SERT) inhibition, 5-hydroxytryptamine (5-HT)3, 7, and 1D receptor antagonism, 1B receptor partial agonism, and 1A receptor agonism. Overarching Goal: The overarching goal of the proposed pilot study is to determine the effectiveness and safety of vortioxetine for the treatment of post-TBI depression and co-morbid NPS. Study Design: The study design will include a DBPCT of 30 TBI patients of all severities who meet the DSM 5 criteria for major depression. A total of 150 will be consented to allow for screen failures. Written informed consent will be obtained from these patients. Subjects will be followed for a total of 12 weeks. Subjects will be randomized to either the vortioxetine arm (N=15) or placebo arm (N=15). The treatment group will receive vortioxetine 10mg per day, which will be increased to 20 mg or decreased to 5 mg, if deemed clinically necessary, at week 4 or 8. Subjects will have a total of 4-5 visits: Baseline evaluation (1 or 2 visits) and follow-up visits at weeks 4, 8 and 12. Well-validated psychiatric instruments will be used to compare the effectiveness of vortioxetine versus placebo treatment at week 12 compared to baseline Relevance: This study has the potential to provide strong preliminary evidence for the use of vortioxetine as a safe and novel agent for treatment of TBI depression and its psychiatric co-morbidities. If found to be effective, results from this study can be used to design larger studies and also determine brain changes associated with its use via neuroimaging.
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....
The purpose of the study is to evaluate whether it is advantageous for adolescents who have recovered from depression after a 6 to 12 week course of antidepressant treatment to stay on the treatment a further 6 months or is it just as helpful to stop the medication after recovery. The hypothesis is that adolescents with major depression who recover from the 6 to 12 week trial of citalopram will be less likely to have a recurrence of depression over a 6 month period if continued on the citalopram as compared to those who discontinue the medication.
Based on the published evidence, collaborative care for depression is both necessary and sufficient for improving care and outcomes for depressed patients in primary care settings. The Translating Initiatives in Depression into Effective Solutions (TIDES) project, upon which ReTIDES is based, developed a VA-adapted version of collaborative care through input from veterans, clinicians, and managers. The initial TIDES project resulted in a clinically stable and effective model as tested in seven primary care practices in three VISNs. This positive result provided the basis for spreading and sustaining the TIDES model and initiating the study of national implementation strategies and issues.
