Filter by:Several open-label trials have shown the therapeutic promise of deep brain stimulation (DBS) targeted to striatal and surrounding capsular areas in treatment-resistant depression (TRD). However, the results of placebo-controlled trials have been mixed, with one showing a large difference between active and sham DBS and another finding no difference. Main aim of this study is establishing whether active DBS results in more treatment responders than sham DBS. Secondary aims are establishing an adverse events profile, establishing effects on quality of life,neuropsychological and neuroimaging measures, and finding predictors of response.
To compare the clinical outcome of patients with Parkinson's disease (PD) treated with directional deep brain (dDBS) stimulation undergoing subthalamic deep brain stimulation operation (STN-DBS) under general anesthesia versus local anesthesia.
The purpose of the proposed study is to determine the feasibility of brief brain stimulation, using a device called Low Intensity Focused Ultrasound Pulsation (LIFUP), for persons with mild cognitive impairment (MCI) or mild (early-stage) Alzheimer's disease (AD). As a secondary aim, the investigators will explore whether this brief intervention is associated with improvements in cognitive functioning immediately and one week following the intervention. Subjects will be randomly assigned to one of two experimental groups: either the LIFUP administration will be designed to increase the activity of neurons in a certain part of the brain or decrease the activity of neurons. The investigators will study up to 8 subjects with MCI or mild AD. Initially, subjects will undergo a screening assessment with a study physician to determine medical and psychiatric history, establish AD diagnosis, and undergo a blood draw, if standard recent labs for dementia and EKG are unavailable. Subjects that meet criteria and agree to participate in the study will undergo a follow-up visit. In the baseline measurement visit, participants will first undergo neuropsychological testing. Participants will be randomly assigned to one of two LIFUP pulsing paradigms. Participants will then be administered four successive LIFUP treatments while the participants are in a functional magnetic resonance imaging (MRI). Sixty minutes following the administration, participants will undergo a second neuropsychological test. A final follow-up assessment will be administered at one week.
