Filter by:The proposed project will evaluate the role of neuroimaging biomarkers of brain aging (i.e., neurodegenerative and vascular brain changes) and mild cognitive impairment in the patterns of treatment response to memantine combined with escitalopram compared to escitalopram and placebo.
The purpose of this research is to learn more about how rTMS works to reduce the symptoms of depression. This information can be used to improve the effectiveness of the treatment. The study will use functional magnetic resonance imaging (fMRI) to examine changes in brain function after treatment with rTMS. fMRI is a safe and painless technique that allows investigators to observe the brain "at work." The investigators will use fMRI to see what regions of the brain become active when you perform a concentration task and how that activation is changed after rTMS.
The study aimed to evaluate the use of exercise as a complementary strategy to treat severe major depression in inpatients. Hypothesis: Exercise can be used as a safe and efficacious complimentary strategy in severe depressed inpatients.
In this pilot study, we propose to test whether high frequency stimulation of the subcallosal cingulate (SCC) is a safe and efficacious antidepressant treatment in five TRD patients, to compare the effects of left-sided vs. right-sided stimulation, and to investigate potential mechanisms of action of this intervention. Importantly, this study will be used to assess the need for and assist in planning a larger, more definitive trial of SCC DBS for TRD.
The long-term goal of this line of research is to determine if decreased vascular reactivity and frontal hypoperfusion is associated with poor response antidepressants. Such perfusion deficits could contribute to antidepressant nonresponse as they would hinder improvements in dorsal system metabolism seen with antidepressant treatment. The objective of the current proposal is to determine if decreased vascular reactivity and frontal hypoperfusion in depressed elders predicts and persists with antidepressant nonremission. The investigators will pursue the primary aim testing the hypothesis that decreased reactivity and hypoperfusion, specifically in the dorsolateral prefrontal cortex and dorsal anterior cingulate cortex, predict antidepressant nonremission. The investigators will enroll 40 depressed elders who will complete clinical, cognitive, and MRI assessments before and after a 12-week open-label antidepressant trial of sertraline.
Major depressive disorder (MDD) is a common psychiatric condition, mostly treated with antidepressant drugs, which are limited for issues such as refractoriness and adverse effects. In this context, the investigators investigate a non-pharmacological treatment known as transcranial direct current stimulation (tDCS). To prove that tDCS is similarly effective than antidepressants would have a tremendous impact in clinical psychiatry, since tDCS is virtually absent of adverse effects. Its ease of use, portability and low price are also interesting characteristics for using in primary and secondary health care. Thus, our aim is to compare tDCS against a fully dosed, effective antidepressant. The study will be a non-inferiority, randomized, double-blinded, placebo-controlled, three-arm trial comparing active tDCS/placebo pill, sham tDCS/escitalopram 20mg/day and sham tDCS/placebo pill. Our primary aim is to show that tDCS is not inferior to escitalopram 20mg/day with a noninferiority margin of at least 50% of the escitalopram-placebo effect.
The purpose of this randomized multiple-site clinical study is to determine whether a revised CATCH-IT (Internet-based depression prevention program) is more effective than a general health education Internet intervention (Health Education)on teens ages 13-18 (inclusive). It is hypothesized that teens in CATCH-IT will exhibit lower levels of depressed mood and/or maintain lower depressive scores over 2 years long-term follow up as compared to teens in Health Education group.
Transcranial electrical stimulation (TES) techniques offer a novel treatment approach for depression and have shown promising efficacy. However, there is no published data to date on their effectiveness as a maintenance treatment. This study will investigate ways of using TES as a maintenance treatment to prevent relapse in depression.
This trial will compare a novel form of rTMS, intermittent Theta Burst Stimulation to the standard conventional high frequency left sided stimulation protocol. The Left dorsolateral prefrontal cortex will be the site of stimulation in both treatment conditions. The site of stimulation will be targeted using MRI co-registration. The study seeks to determine if the two treatment protocols have similar effectiveness in treating major depression.
A non interventional, descriptive, longitudinal cohort study is designed, trying to obtain local data about the prevalence of non remitted depressed patients after an antidepressant treatment, and to get information about sociodemographic and clinical characteristics of these patients as well as features of their treatments and compare them with those of the patients that achieve remission. Also the effect of patient´s expectation in the treatment outcome will be examined.
