Active clinical trials for "Depression"

This study will compare the effectiveness of individual versus interpersonal psychotherapy in treating depressed women with a history of sexual abuse.

This study will determine the effectiveness of offering primary care patients their preferred treatment versus one that is less desirable in improving treatment adherence and outcome.

This is a study of addition of aripirazole to the treatment of bipolar depressed patients who are not better on the medications that they are currently receiving.

This study will determine whether combination treatment driven by patient choice is better than standardized medication treatment at retaining and improving Hispanic patients with major depressive disorder.

In this randomized, double-blind, multi-centre, placebo controlled, exploratory, adaptive design study, the antidepressant and plasma cytokine lowering effects of the GW856553 will be investigated in adult subjects diagnosed with MDD. Subjects will receive oral doses of GW856553 or placebo for six weeks. Safety, tolerability, pharmacokinetics and pharmacodynamics, defined as biomarkers in blood and clinical symptoms, will be assessed. The primary endpoint is the change from baseline associated with GW856553 versus placebo at Week 6 in the Bech (6-item HAMD-17) score. Interim analyses of the primary endpoint will be performed throughout the study to potentially adapt the study design by changing the randomization ratio and/ or reducing the total number of subjects to be randomized into the study. Exploratory analyses will be performed by associating changes in cytokine levels and selected clinical symptoms; PK/PD modelling will also be used to identify the most sensitive clinical and biological markers.

Major depressive disorder is associated with several sleep Polysomnograph (PSG) findings: (1) impaired sleep continuity; (2) non-REM (NREM) changes; and (3) enhanced rapid eye movement (REM) sleep. The first two patterns are common in other psychiatric disorders, while the REM pattern is very characteristic in depression, so the phase-advance theory was accepted by most of psychiatrists. Many researchers have focused on the biological rhythm to investigate the etiological and pathophysiology of depression, and they think depression can be cured if its sleep abnormality is ameliorated. It is well known that most of antidepressants treat depression through 5-hydroxytryptamine (5-HT) neurons. 5-HT also affects the regulation of the sleep-wake cycle and the sleep microarchitecture. Many all-night PSG studies have shown tricyclic antidepressants can ameliorate the sleep architecture abnormality in depression by producing rapid suppression of REM sleep. Compared to TCAs, SSRIs are generally less sedating because of its high selectivity for serotonin receptors. SSRIs can suppress REM sleep and delay REM latency too, but they increase awakenings and reduce SWS at the same time. One PSG study shown sertraline minimally increases sleep efficiency and reduces nocturnal wakefulness time, which may benefit depressive patients. However, this study compared the sleep architecture before and after 12 weeks of pharmacotherapy, so the tolerance to the disturbance of sleep architecture in antidepressants appears to develop over several weeks of treatment. Sertraline has a greater potency against 5-HT reuptake as well as better selectivity for 5-HT reuptake relative to NE reuptake than any other SSRIs, and the relative selectivity of sertraline for inhabiting 5-HT reuptake relative to DA reuptake is somewhat less than of any other SSRIs. So it has chance to exhibit better effect on sleep architecture in depressive patients. Finally, it is difficult to be determined that the unique phenomenon of sertraline is its genuine characteristics or the tolerance after 12-week treatment, so it is crucial to assess the effect of sertraline on sleep architecture in acute treatment. We hypothesized that sertraline could suppress the REM sleep, and have little damage to the sleep architecture of depressive patient.

The purpose of this study is to determine whether transcranial direct current stimulation is an effective treatment for major depression, when compared (and combined) to sertraline and placebo.

The purpose of this study is to provide a comparison of the apathy, depression, and functional outcomes associated with switching to duloxetine or escitalopram in patients who have previously responded to treatment with a selective serotonin reuptake inhibitor (SSRI) for major depressive disorder and who have residual apathy in the absence of depressed mood.

The purpose of this study is to determine the safety and tolerability of BMS-820836 after multiple doses

The purpose of this study is: To determine, in the context of a prospective clinical trial, whether stimulation parameters in PD patients treated with DBS, are associated with antidepressant effects. To determine whether these antidepressant effects are related to or independent of changes in the motor features of PD. To establish a computerized database that includes stimulation parameters and clinical parameters in PD patients treated with DBS. To develop a computer-assisted decision making protocol for programming of DBS parameters in both depressed and non-depressed PD patients.
