Filter by:Neurons are specialized types of cells that are responsible for carrying out the functions of the brain. Neurons communicate with electrical signals. In diseases such as major depression this electrical communication can go awry. One way to change brain function is using electrical stimulation to help alter the communication between groups of neurons in the brain. The purpose of this study is to test a personalized approach to brain stimulation as an intervention for depression. The study researchers will use a surgically implanted device to measure each individual's brain activity related to his/her depression. The researchers will then use small electrical impulses to alter that brain activity and measure whether these changes help reduce depression symptoms. This study is intended for patients with major depression whose symptoms have not been adequately treated with currently available therapies. The device used in this study is called the NeuroPace Responsive Neurostimulation (RNS) System. It is currently FDA approved to treat patients with epilepsy. The study will test whether personalized responsive neurostimulation can safely and effectively treat depression.
Depression is a common psychological disorder seen in 18.5% of Operation Enduring Freedom (OEF), Operation Iraqi Freedom (OIF), and Operation New Dawn (OND) Veterans. Improving the rate of depression recovery and remission is vital to enhance OEF/OIF/OND Veteran's ability to improve work and home adjustment and overall quality of life. OEF/OIF/OND Veterans have reported many barriers to following through with Cognitive therapy skills practice assignments, a key component of CBT therapy, the leading therapy for depression in the VA. Smartphone apps have been identified as a useful widely-used tool to improve the effectiveness of psychological treatments. The investigators propose a full-scale multi-site randomized clinical trial (RCT) to measure the efficacy of CBT-D enhanced with CBT MobileWork-V, a comprehensive CBT skill training smartphone app (the experimental arm) for improving CBT understanding and skill acquisition and depressive symptoms, in OEF/OIF Veterans with depression compared to standard CBT-D.
The primary objective will be to evaluate effectiveness, safety and acceptability of FMT on depressive symptoms at 2 months follow-up in SZ patients with resistant MD.
Repetitive transcranial magnetic stimulation (rTMS) has become a safe and efficacious treatment for patients with treatment-resistant depression. In several studies investigating the antidepressant efficacy of rTMS, it has been shown that in low treatment-resistant patients rTMS is more efficacious than in patients where several treatment attempts have failed. Albeit this finding, most studies to date primarily recruited patients with relatively high degrees of treatment-resistance and there is a lack of trials investigating rTMS as a first-line treatment. Therefore, this trials aims to compare the antidepressant efficacy of 4 weeks open-label theta-burst TMS in non-treatment-resistant patients with a comparable group of treatment-resistant MDD patients.
To assess the safety and tolerability of long-term pimavanserin treatment in subjects with major depressive disorder and inadequate response to antidepressant treatment.
To evaluate the efficacy and safety of adjunctive pimavanserin compared to placebo in subjects with major depressive disorder who have an inadequate response to antidepressant therapy.
This is an add-on study to an existing multimodal neuroimaging study in MDD by investigating the acute effects of DLPFC tDCS on threat vigilance in 24-44 patients with MDD, as part of an open-label treatment intervention study. Behavioral and neural measures of threat vigilance will be taken acutely and investigated as predictors of subsequent treatment response to a four-week, fourteen-session DLPFC tDCS intervention, using a novel home-tDCS protocol. The design takes advantage of an existing rich set of candidate baseline behavioral, neural and molecular measures from the existing neuroimaging study, which could be used to predict treatment response to tDCS and thereby, aid future patient selection for clinical trials.
Biogenetic messages about the etiology of mental illness (e.g., the "chemical imbalance theory" of depression) are increasing but the impact that these have on decision-making and motivation is not yet clear. This study will evaluate the impact of biogenetic feedback on cognitive control and default-mode network functioning, as well as motivation for different psychiatric treatment modalities. Participants with major depressive disorder (MDD) will be instructed that they are being tested for genetic susceptibility to depression and will be randomized to receive feedback that they either do or do not have a genetic predisposition to depression. Before and after receiving this feedback, brain activity will be assessed using high-density electroencephalogram (EEG). The investigators hypothesize that those exposed to the genetic feedback condition will evidence heightened ruminative default mode network activity and perceive medications to be more effective than psychotherapy.
Pilot study design that operationalizes the multimodal manner of care while evaluating changes in depression symptoms, dysmetria, and balance for medication non-responders.
Depression, screened using the Geriatric Depression Scale (GDS) Short Form, has recently been found to be associated with a 3-fold increase in 1-year mortality after aortic valve replacement (AVR) in patients aged 70 or older. The main objective of the study is to evaluate whether the 1-year incidence of major adverse cardiac and cerebrovascular events (MACCEs), evaluated according to the valve academic research consortium 2 (VARC-2 criteria), in patients aged 75 or older who undergo a transcatheter aortic valve implantation (TAVI), should be similar in patients with depression systematically screened (using the 15-item GDS score), confirmed, and handled by a psychiatrist, and in patients without depression detected, after adjusting for frailty criteria and comorbidities.
