Filter by:The purpose of this study is to determine the tolerability and short-term efficacy of a single ketamine infusion for the treatment of adolescents with 1) medication-refractory major depressive disorder (MDD) and/or 2) medication-refractory anxiety disorders (social anxiety disorder, panic disorder, generalized anxiety disorder and/or separation anxiety disorder).
This will be a randomized, single blind study of 6 weeks duration involving the use of auricular acupuncture or sham acupuncture in the adjunctive treatment of depression in college students.
This project aims to use sensors to monitor physiological signals, sleep patterns, vocal characteristics, activity, location and phone usage in study patients with depression who are receiving standard treatment (compared with healthy controls).
This project aims to evaluate whether a dose-response relationship exists between dose of polyunsaturated fatty acids (PUFA), delivered as eicosapentaenoic acid (EPA), and change in markers of inflammation, and whether these effects differ from placebo. A key secondary aim is to evaluate the antidepressant effectiveness of EPA in overweight adult outpatients with current major depressive disorder (MDD). To address these aims, the project will use a four-arm, randomized, parallel-group, placebo-controlled design comparing placebo versus three doses of EPA (1 gm/day, 2 gm/day, or 4 gm/day) administered over 12 weeks. The study is to be conducted at two sites: Emory University School of Medicine, and Massachusetts General Hospital. Eligible participants will be between the ages of 18-80 who have current MDD, are overweight, and who demonstrate peripheral inflammation, defined as an high sensitivity C-reactive protein (hs-CRP) level ≥ 3 mg/L. The primary outcome will be change in plasma interleukin-6 (IL-6) levels and/or mitogen-stimulated peripheral blood mononuclear cells (PBMC) Tumor Necrosis Factor-alpha (TNF-α) expression levels in EPA- versus placebo-treated participants. The results of this investigation are intended to be used to design and power a larger definitive test of the efficacy and biological effects of EPA in patients with major depressive disorder.
On 6 Feb 2014, Pristiq was approved for the treatment of Major Depressive Disorder(MDD) in Korea. In accordance with the Standards for Re-examination of New Drug, it is required to conduct a PMS for 600 patients by 5 Feb 2020. Post marketing surveillance is required to determine any problems or questions associated with Pristiq after marketing, with regard to the following clauses under conditions of general clinical practice. Therefore, through this study, effectiveness and safety of pristiq will be observed.
Ketamine has been shown to decrease symptoms of anxious depression quickly. This decrease has been shown to last for up to one month. MRI technology will be used before and after ketamine for patients with depression to examine the extent to which certain brain areas predict ketamine's antidepressant effects.
Major depressive disorder (MDD) is a common, recurrent, and frequent chronic disorder. Treatment is often challenging; an estimated 20-40% of patients do not benefit sufficiently from existing antidepressant interventions including trials of medication and psychotherapy. A 15-25% of patients manifest a chronic, treatment-resistant course of illness, resulting in a need for additional treatment options. Brain stimulation techniques are considered as a promising therapeutic approach in affective disorders like MDD. Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation method that has been largely investigated in experimental neurosciences and tDCS of the prefrontal cortex (PFC) has been proposed as novel treatment in MDD. In the largest 2x2 factorial randomized controlled trial in MDD to date, Brunoni et al. (2013) have shown that tDCS combined with an Selective Serotonin Reuptake Inhibitor (SSRI; sertraline) resulted in an antidepressant efficacy superior to placebo treatment, tDCS alone and sertraline alone. The purpose of this study is to explore the sustained efficacy and tolerability of repeated tDCS for the treatment of MDD. It is hypothesized that prefrontal tDCS in combination with an SSRI will provoke an antidepressant effect while antidepressant medication alone (sham tDCS) did not. This will be measured by the change from baseline in the Montgomery Åsberg Depression Rating Scale (MADRS) scores after 6 weeks of treatment. In this randomized, placebo-controlled multicenter trial (5 centers involved) patients with a diagnosis of MDD receive a 6-weeks treatment with prefrontal tDCS (anode over electrode position F3, cathode over F4, 5 sessions/week for 4 weeks followed by 2 sessions/week for 2 weeks, 24 treatments in sum, 30min/day, 2mA intensity) or sham tDCS (frequency and duration correspondent active tDCS, ramp in and ramp out periods only without intermittent stimulation), as adjunctive treatment with a SSRI. Follow-up per patient is 3 and 6 months after the last tDCS treatment session. Before, during and after the treatment period different assessment scales will be conducted to record neuropsychological features and the course of the individual symptomatology.
The purpose of this study is to understand if there is a relationship between the way that emotions are regulated by the brain and the way that heart rate is regulated by the brain. The study also seeks to understand whether having depression changes the way that emotions and heart rate are regulated.
In this proof of concept study, the investigators plan to administer iv ketamine interleaved with ECT days. Patients with treatment resistant depression who are deemed to be eligible for ECT treatment will randomly be assigned to either ketamine or active placebo.
Cognitive dysfunction is a highly persistent, pervasive and progressive abnormality in young adults (i.e., 18-65 years) with MDD. It has also been shown that among adults with MDD who are gainfully employed, measures of cognition are a greater determinant of overall workplace performance than is total depression symptom severity. Several lines of evidence indicate that cognitive deficits that persist between episodes of depression are critical determinants of functional recovery in the workplace. The functional implications associated with cognitive impairment provide the impetus for systematic evaluation, measurement and assessment of the domains of cognition expected to be impaired in this patient population. To date, no measurement tool has been sufficiently validated and/or determined to be sensitive to the cognitive deficits in younger adults with MDD. Major limitations of available comprehensive psychometric tools include relative lack of availability, cost, lack of access to most healthcare providers, and above all else, the lengthy time to administer. Moreover, the need for a psychometrist to interpret the results adds to the complexity and the costliness of such an endeavor. It is imperative that any tool recommended for clinical utility be aligned with the busy nature of a high-volume clinical practice. The ideal gold standard tool for assessing the presence of cognitive dysfunction in MDD in the clinical environment should include, but not be limited to, features such as good conceptual coverage of cognitive domains affected in MDD, good sensitivity and reliability, and it should be relatively uninfluenced by culture effects and practice effects. The tool would also need to be brief, easy to administer and interpret, and complement busy clinical practice. This study is designed to validate a brief user-friendly tool capable of detecting deficit in cognitive performance among adults with MDD. Data will be gathered with the aim to determine whether the proposed tool identifies cognitive deficits in adults with MDD and differentiates the clinical MDD population from healthy controls. It is anticipated that the THINC-it tool will be free of charge and downloadable from the THINC-it website for use in the primary care and specialty setting. The THINC-it tool will be accessible via computers/tablets, will take 20 minutes to self-administer in a clinical setting, and the performance results will be immediately available.
