Active clinical trials for "Depression"

Studies have shown that people with certain disorders have an increased risk of developing a condition called Metabolic Syndrome (MS). In this study, the investigators want to learn more about MS among people staying in the hospital for treatment of Major Depressive Disorder (MDD) and also Major Depressive Disorder with Psychotic Features (MDpsy). The investigators also want to learn more about a stress hormone called cortisol that is made in the body. Those who take part in this study will answer some questionnaires, be given some psychiatric interviews, and have some blood taken along with a urine sample. The investigators believe that patients in the hospital with MDpsy will have higher baseline rates of MS factors, cortisol levels, dexamethasone non-suppression, and insulin resistance, compared with MDD alone.

The primary objective of this study is to assess the therapeutic effect of Buprenorphine in MDD population. The secondary objectives of this study are to assess the therapeutic effect, the feasibility and safety of buprenorphine in a MDD population.

This is a non-interventional study to review safety data on administration of desvenlafaxine succinate among Filipino patients with MDD and VMS per usual clinical practice within the first three years post commercial distribution.

The main objective of this study is to characterize a range of brain activation symptoms associated with major depression in peri- and post-menopausal women. Also, assessing brain activation before and after the treatment might help to uncover some mechanisms associated with the pathophysiology of depression and menopause.

Transcranial direct current stimulation (tDCS) is a noninvasive method to activate or de-activate neurons in superficial regions of the brain through the induction of weak electric currents in the brain tissue delivered by two scalp electrodes. Initial studies have shown tDCS to be effective for treating major depressive disorder (MDD), although there are negative trials in the specialized literature. One reason for these discrepant results might be that the duration of tDCS treatment in clinical trials to date (up to 2 weeks) is still insufficient to produce consistent clinical improvements. Thus, we intend to assess, in a sample of outpatients with MDD, whether a 3-week adjunctive course of active tDCS over the left dorsolateral prefrontal cortex is associated with a significant clinical improvement when compared to sham tDCS. The investigators hypothesize that subjects receiving active tDCS will present with significantly higher response and remission rates at weeks 3.

There is strong evidence that patients with major depressive disorder (MDD) are at increased risk of developing coronary heart disease (CHD). This elevated risk is independent of classical risk factors such as smoking, obesity, hypercholesterolemia, diabetes and hypertension. The risk of CHD is increased 1½-2 fold in those with minor depression and 3-4½ fold in subjects with MDD. Put simply, the relative risk of developing CHD is proportional to the severity of the depression. While the mechanism of increased cardiac risk attributable to MDD is not known disturbances in autonomic function most likely do play a part. In untreated patients with MDD (with no underlying CHD) the investigators have identified that a marked sympathetic nervous activation and diminished heart rate variability (HRV) occurs in a proportion (approximately one third) of patients. Diminished HRV has been linked to increased incidence rates of acute cardiac events in conditions such as hypertension, diabetes and myocardial infarction. Importantly, whether treating depression actually improves the risk of: (1) CHD development or (2) recurrence of cardiac events in patients with existing CHD remains unknown. The investigators, and others, have provided a growing body of evidence linking elevated sympathetic activity and exaggerated sympathetic responses to stress to early stages of end organ dysfunction and markers of disease development. Of particular note, in addition to possible effects on HRV is the association of chronic sympathetic nervous activation to: (a) abnormal blood pressure regulation and (b) the development of insulin resistance. The investigators therefore plan to examine the cardiovascular effects of two different antidepressant medications, agomelatine and escitalopram, in patients with MDD. In addition, the investigators plan to investigate the effects these two medications have on sympathetic nervous system activity, blood pressure, HRV, endothelial function, metabolic and psychological effects. Findings from this study will assist us to identify of biological correlates of sympathetic nervous activation which will enable us to: (1) identify those at potentially increased cardiac risk, and (2) potentially implement additional therapeutic strategies in order to reduce cardiac risk. Indeed, it is not known whether antidepressant treatment alone would be sufficient to reverse any adverse effects of sympathetic nervous activation. This study aims to answer this important clinical question.

The purpose of this study is to determine the efficacy of a SSRI, cognitive-bahavioral-therapy and a free choice between SSRI and CBT in a sample of primary care patients suffering from mild to moderate depression. Hypotheses: SSRI is superior to placebo CBT is superior to a non-specific supporting group therapy

The purpose of the study is to explore to what extent continuing the antidepressant medication citalopram (Celexa), after depression has responded to treatment, helps prevent the return of depressive symptoms in patients with recent traumatic brain injury (TBI).

This study evaluates the relationship between mood changes and hormones in women with postpartum depression (PPD). This is an observational study; volunteers who participate will not receive any new or experimental therapies. PPD is similar to major depression, but develops around the time a woman gives birth. Women with PPD often suffer serious physical and emotional impairments. Controversy exists regarding the role of hormone changes in postpartum depression. This study will examine the role of hormone changes in three groups of women: those who recently gave birth and have mild to moderately severe PDD (Group 1), women who recently gave birth and do not have PDD (Group 2), and those who are currently pregnant and experienced an episode of PDD with a previous birth (Group 3). Participants will be screened with a medical history, physical examination, and blood and urine tests. Upon study entry, they will be interviewed about their moods, behaviors, and medical status during and immediately following their last pregnancy. Some women will be asked to participate in interviews, psychological tests, and blood tests. They will also complete self-rating scales and may be asked to collect samples of their urine. Women in Group 3 will complete self-rating scales for 6 months postpartum. Participants will participate in genetic studies that involve completing a questionnaire and providing a blood sample. If the participant allows, sisters and parents may be asked to provide a blood sample and undergo a psychiatric interview. Participants who meet the criteria for minor depression or major depression that is no greater than moderate severity will be asked to participate in a companion study that will evaluate the effectiveness of estradiol in reducing depression symptoms. ...

The Overall Aim of the this project is to compare treatment outcomes and change in putative treatment mediators in Individual Behavioral Activation Therapy (IBAT) against two active psychological interventions (Coping Cat, PASCET) and a wait-list control. Participants will be 200 youth (ages 9-17) diagnosed with a principal anxiety or depression disorder and their caregivers.
