Filter by:This study is being done to determine whether measures of brain activity (known as cortical excitability and inhibition) collected by Transcranial Magnetic Stimulation (TMS) are different in children and adolescents with depression and children and adolescents that do not have depression.
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.
The main objective of this study is to characterize a range of brain activation symptoms associated with depression and response to treatment in midlife men and women with MDD, using MRI and functional MRI. Moreover, in the female sub-group, the investigators will examine whether these brain activation symptoms are related to menopausal symptoms (i.e., hot flashes and night sweats). Also, assessing brain activation before and after the treatment might help to uncover some mechanisms associated with the pathophysiology of depression and menopause.
The aim of this study is to evaluate the safety and efficacy of theta-burst rTMS in patients with major depression. Patients will be randomized to receive ether left-sided intermittent theta-burst rTMS or rigt-sided continuous theta-burst rTMS or sham theta-burst rTMS over two weeks period with an option for an additional two weeks period, depending on treatment response. Clinical assessments will be performed weekly by the Hamilton depression rating scale. In addition, standard neurophysiological assessment of cortical excitability will be done.
The purpose of this study is to assess the effect of escitalopram on sleep architecture utilizing a prospective design. Hypothesis: Escitalopram will improve REM latency in patients with MDD that have responded clinically to treatment.
We hypothesize that depressed patients who have not responded to their current antidepressant medication will respond to the addition of ropinirole to their current regimen at a rate better than placebo.
The purpose of this study is to determine whether augmentation of antidepressant medication with Omega-3 polyunsaturated fatty acids increases the speed and degree of improvement for patients with major depression
We are conducting an eight week longitudinal study to learn if blood levels of certain naturally occurring compounds and genetic markers differ between patients with depression and healthy adults who are not depressed, and if any such differences relate to memory performance, mood, and neurobiology. We are also interested in how the gut microbiome is affected by antidepressant treatment. We will do this by comparing the unmedicated depressed patients with matched healthy controls at baseline and then following the depressed patients over the course of eight weeks of standardized antidepressant treatment to gauge which baseline abnormalities normalize over the course of treatment.
The investigators propose to answer the following research question: Does a multifaceted, culturally tailored intervention that focuses on the specific concerns and preferences of African American patients with depression and their primary care providers improve the processes and outcomes of care for African Americans to a greater degree than a standard state-of-the art depression intervention? This study will determine whether two new educational programs can improve the care for depression in African Americans. These programs may include visits with a depression case manager and access to educational materials, such as a videotape, a calendar, pamphlets, and books. One program is a standard quality improvement program for depression that has been shown to be effective in most patients. The other program is similar, but has materials that focus more on the patient’s specific culture, beliefs, values, and preferences.
The purpose of this study is to determine whether omega-3 polyunsaturated fatty acids are effective as a monotherapy for depression.
