Filter by:This study will compare the antidepressant effects of propofol at two different doses while measuring potential treatment-related biomarkers.
This is a feasibility study and the goal of this project is to evaluate whether peak ACC GABA and glutamate, quantified as a CSF-corrected absolute concentration percent change from baseline, is associated with clinical remission, Montgomery Asberg Depression Rating Scale (MADRS) total score of <10, to the anti-glutamatergic antidepressant ketamine. As MRS is expensive, we also aim to study a correlation between change in peripheral metabolites (GABA and glutamate) and central GABA and glutamate levels.
The long term follow up of a pilot study in which the invesitagors proposed to test whether high frequency stimulation of the subcallosal cingulate (SCC) is a safe and efficacious antidepressant treatment in five TRD patients, to compare the effects of left-sided vs. right-sided stimulation, and to investigate potential mechanisms of action of this intervention. Importantly, this study will be used to assess the need for and assist in planning a larger, more definitive trial of SCC DBS for TRD.
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.
We propose a clinical study of medial forebrain bundle DBS as a treatment in 20 patients with treatment refractory depression (TRD). Data from the University of Bonn indicates that surgical lesions of the medical forebrain bundle can produce therapeutic benefits in patients with depressive disorders, and suggest that DBS at the same site may also reduce symptomatology in these TRD patients (Schaepfer, 2013). Depression affects up to 10% of the US population and of those at least 10-15% do not benefit from therapies hence why we must explore new treatments. The Percept™ PC system manufactured by Medtronic Neurological will be used in this study. Study subjects will be between the ages of 22 and 70 years of age and suffer from TRD, have failed multiple treatment regimens, including ECT, and remain symptomatic. Those identified as TRD patients will then be enrolled in a clinical pilot study investigating DBS, targeting the MFB.
The goal of this study is to use the Activa Primary Cell + Sensing (PC+S) device to study Latent Field Potential (LFP) in the brains of people with Treatment Resistant Depression (TRD) before and during active stimulation. The ultimate goal is to understand the neural network that causes TRD and the changes that DBS cause in that network that results in the antidepressant effects.
This is a randomized, placebo-controlled double-blind cross-over trial evaluating the safety, efficacy, daily functioning, and health-related quality of life of Subcallosal Cingulate Gyrus Deep Brain Stimulation (SCG DBS) for participants with Treatment-Resistant Depression (TRD). A total of 40 eligible participants will be randomized to four treatment sequences (10 participants per sequence). Each participant will be treated over a 6-month period with active or sham stimulation in which both the participants and the attending psychiatrists will be blinded to treatment allocation.
This study is looking at the safety and efficacy of low field magnetic stimulation (LFMS) for treating patients with treatment resistant depression who are taking an antidepressant that is not working for them.
Recurrent major depressive disorder affects about 3−5% of the population. It is anticipated that by 2020, depression will be the most common cause of disability worldwide in the 18−55 age group. About two−thirds of these patients respond to first−line treatment (antidepressants). In addition, prolonged administration of antidepressants in patients who respond results in remission in 80% of patients per year. However, a significant proportion of patients either fail to respond in spite of determined pharmacological treatments, electroconvulsive therapy and other treatments or do not achieve sustained remission. The personal, psychiatric, medical, social and economic consequences are devastating for these, treatment resistant, patients. This investigation aims to evaluate the feasibility of deep brain stimulation in patients with treatment resistant depression as a viable alternative to ablative neurosurgery.The hypothesis is that some patients will respond to stimulation in one site rather than the other and that some patients will respond to double rather than single site stimulation.
Objective: Chronic epidural cortical stimulation (ECS) involves the neurosurgical placement of an electric wire on the surface of the brain with intermittent activation. Over time, ECS modulates local and distal connected brain regions. It is being currently applied over the motor cortex to treat intractable pain. Because of the important role played by the medial prefrontal cortex in mood regulation, the goal of this study is to apply this minimally invasive neurostimulation modality over medial prefrontal cortex in severely ill depressed subjects who have failed all other attempts at treatment.
