Filter by:There is an urgent need for novel and effective interventions for treatment-resistant depression (TRD). In previous studies, ketamine has been shown to rapidly reduce depressive symptoms; however, the exact mechanisms of action of ketamine remain unknown. There are some preliminary findings to suggest that ketamine may exert its antidepressant effects through promotion of neurogenesis in the dentate gyrus. The aim of this study is to help delineate the neurocognitive effects of ketamine exposure using a behavioral task (specifically, a pattern separation task) and a battery of other well-established cognitive measures. This is an assessment-only study, as we will be recruiting subjects to complete an assessment battery at two time points, before and after receiving ongoing ketamine administrations for at least four weeks.
The goal of the study is to conduct a comparative randomized trial of electroconvulsive therapy (ECT) vs. ketamine for patients with treatment resistant depression (TRD) in a real world setting with patient reported outcomes as primary and secondary outcome measures.
Study TRD subjects' resistance to at least 2 different antidepressants, we hypothesize that because of their significant depression and treatment resistant status they are most likely to exhibit BSMN pathway abnormalities.
This study evaluates an accelerated schedule of theta-burst stimulation using a transcranial magnetic stimulation device for treatment-resistant depression. In a double-blind fashion, half the participants will receive accelerated theta-burst stimulation while half will receive sham treatment.
The goal of this project is to guide rTMS using functional magnetic resonance imaging (fMRI) in individuals with depression who did not respond to standard TMS treatment to evaluate whether targeted TMS using individualized functional MRI scans produce outcome superior to that of conventional approaches. The study team also plans to scan patients with Major Depression Disorder (MDD) patients prescribed to receive standard TMS for the first time before and after which they will have resting-state Functional Magnetic Resonance Imaging (rs-FMRI) scan in order to see if we can predict their responsiveness based on the functional connectivity maps.
The purpose of this pilot study is to obtain information about older Veterans' preferences for treatment of depression and insomnia and to pilot test the feasibility and clinical effect of Brief Behavioral Treatment for Insomnia (BBTI) BBTI for older Veterans living with Treatment Resistant Depression (TRD) and insomnia.
The purpose of this research study is to assess which antidepressants work the best in older adults who have treatment-resistant depression (TRD).
The primary goal of the project is to study the effect of Ketamine on cortical neurophysiological function in TRD patients. The proposal employs robust and non-invasive neurophysiological techniques TMS and EEG to investigate the cortical excitability and oscillatory activity in patients with treatment resistant depression.
This is an open label study with a sample size of 6 to develop deep brain stimulation of the subcallosal cingulate white matter(SCCWM) for late life depression using an experimental medicine approach in which the investigators will program the device based both on 1) a neurophysiologic measure of target engagement and 2) safety (defined as lack of neuropsychiatric worsening and stable neurocognition).
The primary objective of this study is to determine the effectiveness of serial infusions of intravenous (IV) ketamine in adults with treatment resistant depression (TRD).
