Active clinical trials for "Depression"

This study will evaluate the efficacy of ALKS 5461 when administered daily for 4 weeks to adults with Major Depressive Disorder (MDD) and inadequate response to antidepressant therapy.

The purpose of the study is to investigate the effects of an internet-administered, therapist-assisted physical exercise program for the treatment of depression.

This study will evaluate the effectiveness of Sober Network Interpersonal Psychotherapy (IPT) in treating women with depression and comorbid substance abuse.

The purpose of this study is to evaluate the efficacy of ketamine in reducing depressive symptoms in subjects with a comorbid major depressive episode and alcohol dependence. The investigators hypothesize the following for the present study: A single dose of ketamine will induce a rapid, robust and sustained reduction in depressive symptoms in subjects with a comorbid major depressive episode and alcohol dependence relative to placebo as defined by change in Hamilton Depression Rating Scale total scores at 72 hours post infusion. A single dose of ketamine can be delivered safely, with minimal adverse events or complications, in subjects with a comorbid major depressive episode and alcohol dependence.

The investigators will evaluate the efficacy of a comprehensive 12-week contingency management intervention for treating alcohol dependence for persons with severe mental illness who are seen within the context of a community mental health center setting. The primary contingency will be submission of alcohol-free urines. Additional reinforcers will be provided for intensive outpatient addiction treatment attendance. Reinforcers will be vouchers or actual items useful for day-to-day living. Participants will be 120 adults diagnosed with alcohol dependance and severe mental illness.

There is strong evidence that patients with major depressive disorder (MDD) have an increased risk of developing coronary heart disease (CHD). This elevated risk is independent of standard risk factors such as smoking, obesity, high cholesterol, diabetes, and high blood pressure. The relative risk of developing CHD is proportional to the severity of depression (the more severe the depression, the more likely the development of CHD). The sympathetic nervous system (the part of your nervous system that makes your heart beat harder and faster) is responsible for our "flight and fight" response to a threatening situation. It has been determined that increased sympathetic nervous system activation occurs in approximately one in three untreated patients with MDD (with no underlying CHD). There is growing evidence linking elevated sympathetic activity to early stages of kidney dysfunction and an increased incidence of cardiovascular (heart and blood vessel) disease development (eg, heart attacks). Sympathetic nervous system activation over a prolonged period of time may also be associated with abnormal blood pressure regulation and the development of insulin resistance (an important feature of type 2 diabetes). It has been suggested that a certain gene, known as the serotonin transporter (5-HTT) gene, may be involved. In particular, work from our group indicates that a particular type of this gene, the short form (or "short" allele) may be important in linking MDD, sympathetic nervous activation, and increased cardiac risk. This study aims to examine the role of the 5-HTT gene on cardiovascular risk factors associated with elevated sympathetic activity in patients with MDD. Additionally, the study will examine the effect of serotonin re-uptake inhibitor (SSRI) therapy on these parameters. A clearer understanding of these systems and processes will allow for identification of patients with increased cardiac risk and development of risk reduction strategies. Such information is clinically significant given the link between cardiovascular disease and MDD. Hypothesis 1: That MDD patients carrying the s allele of the 5-HTT transporter have higher sympathetic activity than homozygous ll patients. Hypothesis 2: that MDD patients with elevated sympathetic activity display early signs of left ventricular hypertrophy (LVH) and diastolic dysfunction. Hypothesis 3: That MDD patients with high sympathetic activity have greater morning surges in blood pressure than patients with normal sympathetic activity. Hypothesis 4: That MDD patients with elevated sympathetic activity display early signs of insulin resistance. Hypothesis 5: That SSRI therapy, in particular in those who carry the s allele of the 5-HTT, has a favourable effect on blood pressure variability and morning surge in blood pressure, sympathetic stress reactivity, and markers of insulin resistance.

The purpose of this study is to see if using Transcranial LED Therapy (TLT) using the PhotoMedex's Omnilux NEw-U LED helps improve symptoms of major depressive disorder (MDD). TLT works by briefly delivering near-infrared (non-visible) radiations to the forehead. The radiations penetrate the brain and stimulate the cells & metabolism. Our goals are To assess the antidepressant effect of the TLT in depressed subjects. To assess the safety and tolerability of the TLT in depressed subjects To assess the acceptability of the TLT in depressed subjects To pilot test the impact on cognition of the TLT in depressed subjects (Ancillary Study)

The objective of this study is to evaluate the effectiveness of ketamine (infusion of 0.5mg/kg) and venlafaxine compared to the use of venlafaxine alone in the treatment of major depression (MADRS score ≥ 20 ) to six weeks of treatment.

The purpose of this study is to determine whether Method of Levels Cognitive Therapy is an effective intervention for treating clients with a range of presenting problems in primary care by comparing it with a waiting list control condition.

Methamphetamine (MA) is a psychostimulant drug with high abuse potential. MA can be smoked, snorted, injected or ingested orally to produce a release of high levels of dopamine into the brain and reduction of dopamine uptake. Its use results in feelings of pleasure, increased energy, and greater alertness lasting up to 12 hours. In 2010, the National Survey on Drug Use and Health reported that 353,000 Americans aged 12 or older reported being current MA users. Over the past decade MA use rates have fluctuated with current use rates on the decline; however, importantly, even though overall use rates are declining, use rates among males and females are approaching equal proportions. This use rate pattern is unlike other drugs of abuse, which typically demonstrate males using more than females. In some states, more females than males consider MA as their drug of choice. Namely, in a 2010 report in the state of Utah, more females were diagnosed with MA as a primary substance of abuse than males upon admission to treatment. Depression and MA use are highly comorbid. The relationship between MA use and depression is likely bidirectional, with MA use causing changes in mood and being used as a self-medicating behavior to reduce symptoms of depression. Several studies have shown that depression rates are higher in MA-using females compared to their male counterparts. It is likely that neurobiological and psychosocial mechanisms contribute to increased incidence of depressive symptoms in females. No clear treatment model exists to suggest how the comorbidity of depression and MA use is best managed. In studies of antidepressants for treatment of MA withdrawal and dependence, findings have suggested that antidepressants are ineffective for treating depressive symptoms. Creatine is an organic acid occurring naturally in vertebrates, where it takes part in energy homeostasis in tissues with fluctuating energy demands. Exogenous creatine has been shown to increase brain concentrations of PCr. Neuroimaging studies of creatine have shown increased brain phosphocreatine (PCr) content with creatine administration. Therefore, we hypothesize that oral creatine administration will increase PCr levels and reduce depressive symptoms in a sample of depressed female MA users. This hypothesis will be tested by a within subjects design by giving depressed MA using females oral creatine for eight weeks and measuring PCr pre- and post-treatment with magnetic resonance spectroscopy. Moreover, depressive symptoms will be measured by administration of the Hamilton Depression Rating Scale twice weekly during the course of creatine treatment.
