Filter by:This study is designed to test whether low-field magnetic stimulation (LFMS) can relieve some of the symptoms of depression in bipolar disorder or major depression.
The primary aim of the study is to determine whether adjunctive intranasal insulin will exert an antidepressant effect when compared to placebo in adults with major depressive disorder (MDD), insufficiently responsive conventional antidepressants. There are three secondary aims of the study (1) to determine whether adjunctive intranasal insulin will alter emotional processing (i.e., cognitive-affective interface); (2) to determine whether early changes in emotional processing (i.e., after a single dose at 40IU intranasal insulin) predicts symptomatic improvement at study endpoint; and (3) to determine the effect of intranasal insulin on neurocognitive performance (e.g., learning and memory). This initiative represents a proof-of-concept study that insulin is important to depressive symptoms, neurocognitive functioning, and emotional processing deficits in MDD, representing a novel and safe therapeutic avenue.
The purpose of this study is to evaluate the safety and effectiveness of JNJ-18038683 compared to escitalopram and placebo in patients with moderate to severe depression.
We propose to investigate structural and biochemical brain abnormalities in depressed subjects, and the relationship between the presence of such abnormalities and treatment outcome. We will recruit N=20 subjects with major depression disorder and N=20 matched normal controls. The depressed subjects would have previously not responded to an adequate trial with a selective serotonin reuptake inhibitor (SSRI). These depressed subjects will be treated for 4 weeks with the same SSRI antidepressant and with adjuvant triiodothyronine (T3). Structural magnetic resonance images (MRI) and then Phosphorus-31 magnetic resonance spectroscopic imaging (31P-MRSI) data will be obtained two times for each patient (at the beginning and at the end of the study) and one time for the normal controls. We will measure for each depressed subject the number of white matter hyperintensities (WMH); we will also measure the degree of change from baseline in several compounds characteristic for the cellular high-energy phosphate metabolism: the phosphocreatine/inorganic phosphate ratio and the beta-nucleoside triphosphate. We will compare the severity of WMH and the high-energy phosphate metabolism in two groups of depressed subjects (those responding and those not responding to thyroid hormone augmentation) and the normal controls. We hypothesize that: 1. All depressed subjects, when compared with normal controls, will present lower baseline levels of compounds characteristic for the high-energy phosphate metabolism. 2. Depressed subjects responding to T3 augmentation, when compared with subjects not responding to T3 augmentation, will present a larger increase of the high-energy phosphate metabolism.
In usual clinical conditions, depressed patients with no sexual dysfunction, after signing their consent for the dissemination of their clinical information will begin their treatment with any SSRI or a Dual antidepressant as per the best clinical decision of their treating psychiatrist. Sexual dysfunction will be identified along the 6 months of active observation. Psychiatrists will decide to change dose, augment, shift or combine antidepressants at their clinical discretion in the benefit of their patients and all clinical decisions will be recorded.Comparisons among antidepressants will be made in terms of their sexual dysfunction potentiality.
This is a study on the effectiveness, tolerability and safety of oral ziprasidone as monotherapy in patients with major depressive disorder (MDD). Outpatients suffering from MDD will be treated with either ziprasidone or placebo for 12 weeks. Hypothesis: There will be a statistically significant difference in the magnitude of response, as measured by a decrease in baseline 17-item Hamilton Depression Rating Scale (HAM-D-17) scores, between the two treatment groups; the reduction in HAM-D-17 scores will be greater in the ziprasidone monotherapy group than in the placebo group.
As of May 21st, 2012, the purpose of this study is to test the antidepressant effect of ketamine when given repeatedly over a period of 1 week, as well as the use of Lithium as a relapse-prevention strategy for patients with treatment-resistant depression (TRD) who respond to an initial series of ketamine infusions. Ketamine is a Food and Drug Administration approved anesthetic (a drug used to produce loss of consciousness before and during surgery). Ketamine is not approved for the treatment of major depressive disorder and is considered experimental in this study.
Study F1J-US-HMFS comprises two identical multicenter, 9-month, randomized, placebo-controlled, double-blind, trials (HMFSa and HMFSb). The purpose of this study is to compare the efficacy and safety of Duloxetine 60 milligrams (mg) once daily to placebo on depression in patients aged 18-65. Data from the two trials will be reported in both individual and pooled analyses. Pooling the two studies will allow for increased power to detect differences between duloxetine and placebo on secondary and exploratory objectives. Only one data lock is planned for this study, when all patients have completed all study procedures.
To confirm the safety and efficacy of the NCP System in treating patients in a nmajor depressive episode.
The primary purpose of your participation in this study is to help answer the following research question: Whether 12-week administration of EMSAM (selegiline transdermal system) is safe and effective for the treatment of adolescents (aged 12 through 17 years) with Major Depressive Disorder (MDD).
