Filter by:Noninvasive transcranial direct current stimulation (tDCS) is a low-intensity neuromodulation technique of minimal risk that has been used as an experimental procedure for reducing depressive symptoms and symptoms of other brain disorders. Though tDCS applied to prefrontal brain areas is shown to reduce symptoms in some people with major depressive disorder (MDD), the extent of antidepressant response often differs. Methods that map current flow directly in the brain while a person is receiving tDCS and that determine how functional neuroimaging signal changes after a series of tDCS sessions may help us understand how tDCS works, how it can be optimized, and if it can be used as an effective intervention for reducing depressive symptoms. We will investigate these questions in a two-part randomized double blind exploratory clinical trial. The first part of the trial will compare how current flow and functional imaging signal differs in the brain when using tDCS with more focal stimulation, called high definition (HD) tDCS, compared to conventional tDCS (C-tDCS) or sham (non-active) tDCS in patients with MDD. Sixty people with depression (20 in each group) will be randomized to receive either HD-tDCS, C-tDCS or sham-tDCS for a total of 12 sessions each lasting 20 minutes occurring on consecutive weekdays. At the first and last session, subjects will receive 20-30 minutes of active or sham tDCS in the MRI scanner, which will allow us to map tDCS currents, and track changes in regional cerebral blood flow (rCBF) pre-to- post treatment using completely non-invasive methods. At the first and last session and mid-way through the trial, participants will also complete a series of clinical ratings and neurocognitive tests
Worldwide Major Depressive Disorder (MDD) has significant negative personal, societal and economic consequences. Vortioxetine (Brintellix®) is a new antidepressant authorized since 2013. Despite evidence generated from clinical trials which demonstrate that vortioxetine is an efficacious, well-tolerated antidepressant, there is a need to determine the effectiveness of vortioxetine in real life routine practice. The study aim is to examine the real-life effectiveness of vortioxetine on functioning, depressive symptom relief, cognition and quality of life. This is an observational, multi-national, study in patients with MDD initiating treatment with vortioxetine. Information will be collected by the physician, from the patient and their medical record at three time points - baseline, week 12 and week 24 (end of follow-up). This study will be conducted in six countries. In total 2,100 patients are planned for enrolment.
This study aimed to evaluate the therapeutic benefits of pentoxifylline (PTX) in treatment of adult patients with MDD as it has anti-inflammatory and phosphodiastrase inhibition activities.
The primary goal of this pilot study is to investigate whether psilocybin alters neuroplasticity in people with major depressive disorder. The primary hypothesis is that psilocybin will result in neuroplastic changes that parallel improvement in symptoms of depression.
The purpose of the study is to investigate the effect of Food, Gender, and Age on the Pharmacokinetic Profile of SUVN-911 in Healthy Subjects
Tricyclic Antidepressants (TCA's) are the cornerstone of treatment for patients with severe Major Depressive Disorder (sMDD). Current dosing is guided by repeated measurements of blood levels. Compared to patients with a normal metabolization function, for those with increased CYP450 enzyme activity it takes longer to reach a therapeutic drug level. The consequent delay of drug efficacy is associated with a prolonged treatment period, increased risk of suicidal behaviour and eventually lower remission rates. For those with reduced CYP450 activity higher rates of side effects are expected. An innovative TCA dosing strategy, taking the genetic variants of CYP2D6 and CYP2C19 into account may help to reduce the above mentioned problems. Up till now, the current guidelines for CYP450 pharmacogenetics based TCA dosing have not been systematically evaluated for effectiveness and cost-effectiveness in larger groups of patients. Such evaluation is necessary before broad implementation of these guidelines can be advocated. In the present study 200 patients with sMDD who are treated with nortriptyline, clomipramine or imipramine are randomized over two strategies: dosing based both on CYP450-genotype and blood level measurements and dosing as usual (standard doses plus blood levels). We hypothesize that genotype informed dosing results in faster attainment of therapeutic drug levels, lower rates of side effects, earlier symptom relief and lower levels of health- and working related costs.
This is a parallel randomized, double-blinded, sham-controlled clinical trial in which a total of 72 drug-naïve MDD subjects (36 per arm) are randomized to one of two groups: Cognitive-Behavior Therapy (CBT) combined with either active or sham tDCS. The primary outcome is mood improvement, as measured by the Montgomery-Asberg Depression Rating Scale (MADRS). The secondary outcome is to test whether tDCS combined with CBT can engage the proposed mechanistic target, of restoring the prefrontal imbalance and connectivity, by changes over EEG.
This study is a randomized double blind placebo controlled EEG monitored study of deep rTMS treatment to treat adolescent depression. The present study is the first well controlled study to examine the possible clinical utility of deep TMS to treat a severe and life threatening disorder- depression, among adolescents. Patients will be allocated, based on chance, to receive active therapy or a "as if" stimulation, with no knowledge of patient or therapist who receives the active therapy. In addition, a simple and feasible monitoring of brain waves (EEG) will be conducted. This addition will enable us to evaluate the possibility to use biological markers to predict the course of therapy. Our hypothesis is that 1. patients receiving the active therapy will improve significantly more than those who received the "as if" treatment. 2. There will be no significant side effects. 3. The brain waves (as measured by the EEG) will predict treatment response.
Major depressive disorder (MDD) is a serious medical illness associated with significant suicidal risk and marked disability. Despite the availability of numerous treatments, achievement of consistent and favorable long-term outcomes remains challenging. This study will assess the safety, efficacy and tolerability of brexpiprazole as adjunctive therapy to protocol-specific open-label antidepressant therapy.
This study aims to determine whether the GeneSight Psychotropic test can result in better treatment outcomes for patients with treatment-naive major depressive disorder
