Filter by:Creatine as a new therapeutic strategy in depression: A double-blind, parallel, randomized, add-on clinical trial of creatine versus placebo added to antidepressant treatment of patients with major depressive episode.
Studies exploring the efficacy of repetitive transcranial magnetic stimulation (rTMS) as a treatment for refractory major depressive disorder (MDD) have shown significant promise. Despite this, several questions regarding the treatment parameters needed to optimize efficacy remain. Moreover, there is also a lack of clear understanding as to the therapeutic mechanisms involved. For example, several lines of evidence suggest that patients with MDD have deficits in cortical inhibition (CI) and that these deficits are key to understanding the pathophysiology of this disorder. With this study, we seek to confirm the therapeutic potential of an acute course of rTMS for treatment-refractory MDD in a large sample of patients. In addition, we will strive to clarify the neurophysiological mechanisms through which rTMS exerts its therapeutic effects, using both TMS and electroencephalography/event related brain potential (EEG/ERP) measures of neurophysiological activity. Moreover, in this study, we intend to investigate the efficacy of a maintenance course of rTMS in an effort to prevent symptom recurrence.
Major Depressive Disorder (MDD) is a serious illness associated with considerable morbidity, risk of suicide and adverse social consequences (Montgomery et al., 1994a). Cognitive impairment is one of the three major symptom areas of MDD. Specifically, memory impairment and concerns are one of the most commonly reported complaints in MDD. While antidepressant (AD) treatments vary a great deal in their propensity to cause cognitive impairment, there remains a paucity of empirical evidence on the effects of AD treatment on neuropsychological indices of memory functioning in non-geriatric depressed individuals. Hence, comparative effects of various AD drugs on memory functioning remain unclear.The aim of this study is to evaluate multiple aspects of memory functioning (short-term, working memory, verbal, non-verbal, spatial and prospective memory) of MDD patients before and after 8 weeks of antidepressant treatment with bupropion XL or escitalopram.
Despite many available treatments, there are patients with major depression who remain treatment refractory and chronically disabled. For these severely ill patients, several neurosurgical procedures are available where brain lesions are made that interrupt white matter tracts linking orbital frontal cortex to the striatum, resulting in significant therapeutic benefit for many patients. In this study, we will test the safety and efficacy of Deep Brain Stimulation (DBS)--a reversible method used to modulate brain activity--as an alternative to the standard subcaudate tractotomy (SCT). The physiological consequences of this procedure will be mapped longitudinally using positron emission tomography (PET) measures of brain glucose metabolism. Patients will be clinically monitored for 1 year with longitudinal psychiatric, neurological, neurosurgical, neuropsychological and PET imaging examinations to assess treatment efficacy and side effects.
Assessing the effectiveness of Idazoxan as a treatment for depressive patients who did not respond to treatment with SSRI
The purpose is to evaluate the safety and usefulness of the investigational drug, vilazodone in depression.
The purpose of this study is to evaluate the potential early EEG predictors of an individual's response to treatment with antidepressant medications. Objectives: - Prospectively confirm accuracy of current EEG biomarker algorithm - Determine preferred clinical intervention for subjects with negative indicator - Identify predictors of worsening suicide ideation
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 purpose of this study is to determine safety & efficacy of SEROQUEL SR™ in the treatment of major depressive disorder compared to placebo & to evaluate quality of sleep, overall quality of life, and effect, if any, on anxiety and satisfaction PLEASE NOTE: Seroquel SR and Seroquel XR refer to the same formulation. The SR designation was changed to XR after consultation with FDA.
The purpose of this study is to compare the antidepressant efficacy, safety, and tolerability of DVS-SR in subjects receiving daily doses of 50 mg or 100 mg of DVS-SR versus subjects receiving placebo.
