Filter by: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 the study is to see if galantamine HBr (Razadyne) is safe and can help treat problems with thinking and memory caused by electroconvulsive therapy (ECT).
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.
The purpose of this study is to determine the safety and tolerability of a new drug, GSK163090, which is being developed for the treatment of depression and anxiety disorders.
The purpose of the study is to assess the safety and effectiveness of the combination of aripiprazole (Abilify) and selective serotonin reuptake inhibitors (SSRIs) in subjects with psychotic major depression.
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.
The purpose of this study is to determine the efficacy of SA4503 compared to placebo in the treatment of subjects with major depressive disorder (MDD). Secondary, to evaluate the safety of SA4503 compared to placebo in subjects with MDD.
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.
