Filter by:The purpose of this study is to examine the proposed suicide preventive effects of lithium in a randomized controlled trial within a group of individuals with depressive disorders. The hypothesis being tested is that lithium treatment will significantly reduce the risk for another suicide attempt.
This study will compare the effectiveness of a cognitive behavioral intervention versus usual clinic care in helping HIV infected adults with depression to take their HIV medications on schedule.
To investigate the effect of Escitalopram in a large and diverse of dementia patients suffering from depression.
The overall purpose of this project is to evaluate the effect of sertraline administration on the binding of 123-I mZINT in 10 healthy subjects. All study procedures will be conducted at the Institute for Neurodegenerative Disorders (IND) and Molecular NeuroImaging (MNI) in New Haven, CT.
This is a study to assess the effectiveness and safety of repetitive transcranial magnetic stimulation (rTMS) as a treatment for depressed 13-18 year olds. In rTMS high-intensity, fluctuating magnetic fields non-invasively stimulate the cortex of the brain depolarizing neurons. No anesthetic is required and the treatment in subconvulsive. Recent studies suggest that rTMS can be an effective treatment for depressive illness in adults (Loo and Mitchell, 2005) and appears to be quite safe. Minimal data of TMS use in adolescents psychiatric disorders. Data only existed in seven patients of the four that were depressed two showed improvement in their depression (Quintana, 2005). No sham-controlled studies have been conducted. The investigators wish to assess this in a sham-controlled study of 30 adolescents. The investigators hypothesize that rTMS will have an antidepressant effect and produce no neuropsychological impairment.
We will study patients with a current major depressive episode, comorbid alcoholism and a history of a past suicide attempt. All subjects with alcohol dependence will be evaluated for risk of alcohol withdrawal prior to randomization. The study will provide six months of antidepressant pharmacotherapy as well as psychotherapy focused on alcohol relapse prevention. Patients will also be encouraged to attend daily Alcoholics Anonymous meetings. The outcome measures will be: 1) occurrence of suicide events; 2) reduction of suicidal ideation; 3) reduction in neuropsychological measures of impulsivity.
The primary study comparing effectiveness for suicidal ideation and/or behavior of two antidepressant medications in depressed patients who have attempted suicide or are currently experiencing suicidal thoughts has been completed. A secondary study component using functional magnetic resonance imaging (fMRI) to investigate different medication effects on reward processing in the same sample is ongoing.
The purpose of this study is to investigate whether the addition of galantamine to a commonly used antidepressant, escitalopram (Lexapro), will be useful in the treatment of memory and other thinking problems that are frequently seen in depression. At present, galantamine is approved for use in the treatment of Alzheimer’s disease or dementia, but not for use for the treatment of depression in younger patients. Possible genetic effects of depressed individuals will also be studied. This study is involved in collecting blood from patients with depression. DNA, the genetic material in our cells, will be obtained from these blood samples. The DNA will be studied to determine the contribution of different genes to the development of depression. These blood samples are extremely useful to researchers who are trying to determine the genetic risk factors that may lead to depression.
This study is being done to look at how well people respond to two very different drug treatments for depression. Clinically, people with depression can respond differently to drug treatments for reasons which are not always clear. Some of our own recent research suggests that people with depression who have a family history of bipolar disorder or completed suicide, may react differently to standard antidepressant medications than those without such a family history. Our data shows that family history of completed suicide, as well as the known predictor of family history of bipolar disorder, may help identify a pre-bipolar high risk group i.e. they currently have depression but at some future date will declare a bipolar illness (manic-depression) by virtue of development of a manic episode also. Our research suggests that treatment- emergent symptoms in response to a trial of antidepressant, such as agitation may be strong predictors of future bipolarity and inherently dangerous particularly as they are not ascribed to the antidepressant treatment. Finally, it is possible that this subgroup of those with depressive illness may respond better and more safely to lithium, a mood stabiliser used in known bipolar depression. The objective of this proposal is to investigate response to acute lithium treatment in subjects who meet the diagnostic criteria for major depression, but who are potentially at risk for bipolar disorder, by virtue of family history of bipolarity or completed suicide.
Sexual dysfunction is a common side effect of selective serotonin reuptake inhibitors (SSRIs). The hypotheses of this study are that:1. subjects with major depression or dysthymia who are being treated with an SSRI and experiencing treatment-related sexual dysfunction will experience less sexual dysfunction if they are switched to duloxetine, and 2. they will experience either improved antidepressant response or no loss of antidepressant response.
