Filter by:This pilot study will assess the efficacy of several sequential pharmacological treatments for patients with Refractory Depression.
The proposed research aims to compare the onset of action and the efficacy of fludrocortisone, a mineralocorticoid receptor agonist vs. spironolactone, a mineralocorticoid antagonist, vs. placebo as augmentation to a selective serotonin reuptake inhibitor (SSRI) in 65 inpatients with severe depression. The study will also explore the utility of the hypothalamic-pituitary-adrenal (HPA) axis in predicting treatment response. The study will be a 5-week randomized and double-blind trial of fludrocortisone vs. spironolactone vs. placebo during three years.
40 patients with the diagnosis of major depression are included. There are two interventions: partial sleep deprivation (PSD) and normal night sleep (CTRL). Patients are randomly assigned to PSD-(2 undisturbed nights)-CTRL or CTRL-(2 undisturbed nights)-PSD. Cytokine-status, neuropsychological and psychopathometric status are assessed pre and post each interventional and control condition.
The purpose of this study is to determine whether augmentation of antidepressant medication with Omega-3 polyunsaturated fatty acids increases the speed and degree of improvement for patients with major depression
Context - As men age, testosterone levels decline leading to symptoms that overlap with the symptoms of major depression. Little is known about the potential role of testosterone in the treatment of major depression.Objective - To assess the levels of bioavailable testosterone and total levels of testosterone in men diagnosed with major depressive disorder between the ages of 40 and 65.Design, Setting and Participants - 50 men between the ages of 40 and 65 and who suffer from major depressive disorder will be compared with 50 age matched healthy controls in an outpatient hospital setting. Main Outcome Measures - Bioavailable testosterone and total testosterone levels will be measured as well as blood pressure, pulse rate, height, weight, waist and hip measurements. Medical and psychiatric history will be assessed by the study physician. The Mini International Neuropsychiatric Interview (MINI) will be used to administered by the physician to ensure that the patient meets the DSM-IV criteria for Major Depression. The Hamilton Depression Rating Scale (HAM-D-17) will be used to assess depression symptom severity. A Symptom/Side Effect Rating Scale will also be administered to measure the presence and severity of side effects that each patient may be experiencing. In addition, the SEX FX questionnaire will be administered. Each patient will be asked to complete a series of self-report measures including the Social Adaptation Self-Evaluation Scale Questionnaire (SASS), the Androgen Deficiency in Aging Males (ADAM) and the Beck Depression Inventory (BDI-II).
Objective of this 16-week, open-label study is to assess the safety and tolerability of once daily application of three doses of STS during continuous dosing in the treatment of elderly subjects with major depression. Subjects will have study visits (clinic visits) at beginning of study (baseline) and study weeks 1, 3, 5, 8, 12, and 16.
The study includes two components：(1) cross-sectional (Study I), and (2) longitudinal treatment trial (Study II). The cross-sectional component will include all subjects initially recruited for the parent project. Genotyping characteristics will be compared with clinical status (i.e., recovered vs symptomatic). The treatment trial component (one) will include a subset of the subjects (n = 400) who remain significantly depressed. They will be randomly assigned to 8-weeks of treatment with either citalopram or paroxetine. With such a design, we wish to test the following hypotheses： Ⅰ. Depressed patients with the short variant of the serotonin transporter (5HTTLPR) will respond faster and better to antidepressants compared to their counterparts with the long variant. Concurrently, patients with the 5-HTT Stin2 12/12 allele will also show better response as compared to those with the 10/12 allele. Ⅱ. Depressed patients who are homozygous for deficient or less active CYP2D6 or CYP2C19 enzyme(s) will be more likely to show treatment emergent side effects compared to subjects with the wildtype alleles. Specifically, in Study II, CYP2D6 polymorphism will predict PAR but not CIT side effects and CYP2C19 polymorphism will be associated with CIT but not PAR side effects.
Our goal is to study pharmacogenetics in Mexican-Americans, using depression treatments as a proof of the concept that pharmacogenetic approaches can be used to optimize treatment strategies for common and complex disorders in this population.
The objective of this project is to examine the state of the brain in people over 50 years old suffering from late-onset depression by means of an extensive clinical assessment programme, including magnetic resonance imaging (MRI), neuropsychological testing, neurological examination, eye examination as well as blood and saliva samples. The results are to be compared with results from a control group matched for gender and age.
This is a research study to determine whether omega-3 fatty acid supplementation, when taken with the antidepressant medication escitalopram (Lexapro), helps to improve depressive symptoms in individuals who have major depressive disorder (MDD). Omega-3 fatty acids are found in foods including walnuts, some fruits and vegetables, and coldwater fish such as herring, mackerel, sturgeon, and anchovies.
