Filter by:The major objective of this observational study is to describe clinical outcomes of patients in the UK receiving treatment with the NeuroStar TMS Therapy system in routine clinical practice.
Depression is a highly prevalent condition characterized by persistent low mood, energy, and activity that can affect one's thoughts, mood, behavior, and sense of well-being. Repetitive transcranial magnetic stimulation (rTMS), a non-invasive neuromodulatory technique, is an effective treatment for depression. However, remission rates are suboptimal and ideal stimulation parameters are unknown. The overarching goal of this study is to elucidate how brain changes accumulate during rTMS, and how these changes relate to clinical outcome. I plan to recruit patients with medication-resistant depression and treat with four weeks of rTMS in a randomized, double-blind, sham-controlled fashion. I will measure brain changes using TMS-EEG and determine how these changes relate to clinical outcome. This study will 1) test how brain changes relate to clinical outcome and 2) establish a computational model to help predict outcome and propose novel treatment protocols.
The study will evaluate the efficacy, safety, and tolerability of 450 milligrams (mg) of Rapastinel, compared to 10 mg of Vortixetine and placebo in participants with major depressive disorder (MDD).
DELPhI acquisition and analysis software, a QuantalX Neuroscience development, which is designed to measure, analyze, and display brain electrical activity of human electroencephalogram (EEG), to transcranial magnetic stimulation (TMS), will be used to evaluate different psychiatric conditions.
The effectiveness of glabellar injection of botulinum toxin type A (BTA) in treating depression has not yet been investigated in elderly patients. The study aims in addressing the question if glabellar injection of BTA is effective in treating geriatric depression.
The investigators are testing the efficacy of Smartphone-delivered cognitive behavioral therapy (CBT) treatment for major depressive disorder (MDD). The investigators hypothesize that participants receiving app-CBT will have greater improvement in QIDS-C scores than those in the waitlist condition at treatment endpoint (week 8).
The investigators will acquire simultaneous EEG and fMRI data from Veterans with depression and schizophrenia and mentally healthy Veterans to assess early sensory responses, context updating, and responses to emotional images. Understanding how rumination affects engagement with the environment is the first step towards assessing its far-reaching cognitive and emotional costs, which cut across traditional diagnostic boundaries. Understanding how mindfulness restores information processing will increase our understanding of how, and for whom, it works.
This study will enroll participants who have been diagnosed with type 2 diabetes and are experiencing symptoms of depression. This study will look at an anti-depressant medication called vortioxetine (Trintellix). Vortioxetine is an oral medication (pill) that has been approved by the US Food and Drug Administration (FDA) to treat depression in adults. The purpose of this study is to look at what effects (if any) vortioxetine may have on symptoms of depression in patients with type 2 diabetes. This study will also look at what effects (if any) vortioxetine has on blood sugar, and how vortioxetine may improve the way our brains are able to adapt and respond to stress.
The primary study intent is to examine biological mechanisms associated with acute and chronic treatment responses in major depressive disorder (MDD). It is hypothesized that treatment responsiveness, representing endogenous opioid system function, will be associated with acute improvements in mood state over a 10-week treatment trial in MDD. Potential (bio) markers of treatment effects will be tested against psychophysical responses to placebo and active treatments.
Demonstrate the acute effects of ketamine on endogenous µ-opioid neurotransmission in humans.
