Filter by:The primary objective of this study is to assess short, mid and long-term clinical outcomes in patients with difficult to treat depression (such as patients with treatment resistant depression) treated with Vagus Nerve Stimulation (VNS) Therapy as adjunctive therapy.
The purpose of this study is to evaluate the efficacy of TAK-653 compared with placebo in maintaining the effect of ketamine treatment on depressive symptoms.
The purpose of this research study is to compare the antidepressant effect of lithium versus placebo in adults receiving ketamine. Lithium is available commercially for depression; ketamine is available commercially and can help the symptoms of depression; however, it has not been approved by the U.S. Food and Drug Administration (FDA) for this use. The FDA has allowed the use of this drug in this research study.
Antidepressant-free unipolar melancholic depressed patients (at least stage 2 treatment-resistant) will be selected by a certified psychiatrist, who will administer (semi-)structured clinical interviews. Because concomitant antidepressant treatment can confound outcome results, all patients will go through a medication washout before entering the study and they will be free from any antidepressant, neuroleptic and mood stabilizer for at least two weeks before entering the treatment protocol. Only habitual benzodiazepine agents will be allowed. STEP 1: Patients will be treated with in total 20 accelerated intermittent Theta Burst Stimulation (aiTBS) sessions (3000 pulses/session) over the left dorsolateral prefrontal cortex, which will be spread over 4 days. On each stimulation day, a given patient will receive 5 sessions with a between-session delay of 15 minutes. Patients will be randomized to receive either the real aiTBS or sham treatment (first week). However, the sham group will receive real aiTBS treatment with 10 days' time interval. The investigators expect that real aiTBS treatment and not sham will result in a significant and clinical meaningful response. STEP 2: To optimize treatment and reduce relapse following the iTBS treatment, in a stepped care approach, all patients then continue with cognitive control training (CCT) ten days later. This CCT consists of 20 sessions, spread over 4 weeks. Patients will be randomized to receive either real CCT or a control training. During this follow-up treatment, all patients will be prescribed antidepressant medication (SSRI) again. As iTBS treatment effects are known to decline over time, the investigators expect that combining aiTBS with a follow-up CCT therapy will stabilize the clinical effects over time compared to receiving the iTBS treatment alone. For baseline comparisons, patients will be closely matched for gender and age with never-depressed, medication-free healthy volunteers. No volunteer will undergo treatment.
To determine if an high intensity ketamine with ECT rescue (HIKER) approach for treatment resistant depression will: 1) reduce patient suffering by hastening disease remission, 2) have fewer side effects, 3) reduce the need for ECT, and 4) be preferred by most patients. Half of participants will be randomized to the HIKER arm and receive high intensity ketamine treatment for eight consecutive days, and the other half will be assigned to the ECT with ketamine anesthesia (EAST) arm and receive 8 ECT treatments (2-3 treatment/week)
Background Major depression is associated with morbidity and increased mortality. Along with the psychological strain depression represents a high socioeconomic burden costing Europe more than €113 billion/year. About one third of patients do not respond to appropriate therapy. Theta-burst stimulation (TBS), a form of transcranial magnetic stimulation is an emerging treatment for patients for whom pharmacological treatment is ineffective or not appropriate. Based on two different theories of prefrontal dysfunction two TBS-protocols should have the most antidepressant effects. However, no study so far has compared the two approaches or systematically investigated their differential effects on brain function and on a symptom level. Objectives of the study The aim of this study is to test two TBS protocols on symptom improvement and associated brain function in patients with treatment resistant depression (TRD): iTBS over bilateral DLPFC and iTBS over left and cTBS over right DLPFC. As stimulation over non-motor regions offers no direct readout, fMRI at baseline and after treatment will be harnessed to quantify an effect on brain activity and functional network metrics. Study population 80 patients with TRD will be enrolled with 40 patients receiving the one, and 40 patients receiving the other TBS protocol for a treatment period of three weeks. Study design The study is designed as a longitudinal, randomized and double-blind clinical trial. At baseline and after treatment, patients will undergo psychiatric testing using several symptom scales including the Hamilton Depression Rating Scale (HAMD-17), the Beck Depression Inventory (BDI-II), the Inventory of Depressive Symptomatology (IDS-C) and the State-Trait Anxiety Inventory (STAI). Changes in HAMD-17 scores are defined as primary endpoint. Moreover MRI scans before and after treatment will include structural and functional MRI sequences as well as diffusion weighted imaging (DWI) sequence. Functional connectivity and BOLD responses will serve as primary imaging endpoints. A follow-up visit 2 weeks and a final examination 4 weeks after treatment will elucidate durability of effects. Relevance and implications of the study By investigating which approach is superior for which symptoms our study will contribute to the development of personalized treatment, the reduction of personal suffering and the reduction of costs and occupational disability.
This study evaluates an accelerated schedule of theta-burst stimulation using a transcranial magnetic stimulation device for treatment-resistant depression. In this open label study, all participants will receive accelerated theta-burst stimulation.
This trial aims to assess the efficacy and tolerability of Magnetic Seizure Therapy (MST) as an alternative to electroconvulsive therapy (ECT) for depression. Even with multiple medication trials, 30 - 40% of patients will experience a pharmacologically resistant form of illness. The ineffectiveness of current treatments for major depressive disorder (MDD) coupled with the economic burden associated with the disorder engenders a need for novel therapeutic interventions that can provide greater response and remission rates.
This study is aimed to help us learn about the effects of Transcranial Magnetic Stimulation at the forehead versus the left side of the head for treatment of Treatment Resistant Depression.
The investigators are doing this research study to find out if using aspirin along with antidepressant treatment can lessen symptoms of depression. This study also aims to find out if some people improve more from taking aspirin than others. The investigators also want to see if it is possible to predict which participants will do better based on a blood test. Aspirin is approved by the U.S. Food and Drug Administration (FDA) as an over-the-counter pain medication. But, aspirin is not approved by the FDA to make antidepressant treatment better. This research study will compare aspirin to placebo.
