Filter by:The Etude Study is a multi-center, four-arm prospective dose-adjusting study designed to assess the tolerability, safety and efficacy of non-invasive sensory stimulation for patients with cognitive impairment.
Electrical activity in the brain known as "gamma" brainwaves help connect and process information throughout the brain. These gamma waves are diminished in Alzheimer's disease. New research in Alzheimer's disease mouse models shows that exposure to light flickering at the rate of 40 flashes per second or 40Hz increased gamma brainwaves and led to clearing of beta amyloid plaques in the brain, a key abnormality in Alzheimer's disease. This project will test the ability of a novel iPad App (AlzLife https://www.alz.life/) that delivers light therapy at 40 Hz combined with cognitive therapy to improve cognition, function, and quality of life in Alzheimer's disease.
This study tests the effectiveness of using a new mobile application (Bingocize®) to improve older adults' (a) adherence to an engaging exercise program, and (b) aspects of functional performance, health knowledge, dietary habits, and cognition.
The EuRIDICE trial will study whether haloperidol as a first line treatment for ICU delirium reduces delirium duration (and severity). Adverse outcomes typically associated with delirium will also be studied and include long term cognition, functional outcome and quality of life. Further, patient and family experiences and cost-effectiveness will be assessed. Finally, safety concerns associated with the use of haloperidol in this vulnerable population will be studied.
This study investigates the effect of dietary inorganic nitrate supplementation on 1) large elastic artery stiffness and hemodynamics and 2) cerebrovascular function in middle-aged and older adults. Participants will be randomized to consume either nitrate-containing or nitrate-depleted beetroot juice.
This Phase II randomized clinical trial aims to test if supplementation with high dose oral vitamin D will successfully correct vitamin D insufficiency, compared to treatment with standard (RDA) dose vitamin D in a diverse community-based elderly cohort. The effect of high-dose vs. standard-dose vitamin D on altering cognitive trajectories will also be assessed and data will be expected to be used in designing a potential definitive Phase III trial in elderly groups at risk for dementia. A total of 180 elderly persons with longitudinal biomarkers, neuropsychological testing and brain MRI scans will be enrolled, with 152 (~50 with MCI, 50 with mild AD and 50 with no cognitive impairment) expected to complete the 3½-year study. One-half of each diagnostic group will be randomized to treatment with high-dose vitamin D3 (4,000 IU daily) or to standard dose Vitamin D (600 IU capsule daily + ~200 IU dietary = ~800 IU total/day). Longitudinal MRI analyses will provide an estimate of the treatment effect size on brain atrophy rate. Vitamin D receptor genotype polymorphisms and their impact on response to oral supplementation will also be examined. If vitamin D supplementation improves cognitive outcome, this could have a large impact on the public health, since low vitamin D status is a common, readably treatable condition which may provide a novel window to prevent dementia and AD. Furthermore, the higher prevalence of AD and dementia in African Americans and Latinos could be partially attributable to vitamin D insufficiency.
The purpose of this study is to assess cognitive function using a rapid, portable, computerized neurocognitive testing device in a wide variety of clinical settings.
The current study is designed to test the effectiveness of online programs for memory and executive functions in healthy aging. The investigators are testing online adaptations of two cognitive interventions that have been extensively studied, validated, and implemented in clinical settings: The Memory & Aging Program (MAP) targets normal memory change in healthy aging, and Goal Management Training (GMT) targets executive functioning deficits in a variety of cognitive and neurological conditions including healthy aging. Both programs combine psycho-education, targeted skills training and clinical support to empower participants with knowledge and strategies to harness their cognitive faculties. These programs are being tested against a waitlist control as well as against a commercial/research brain training platform (Cambridge Brain Sciences) in a design comparing performance on memory and executive functioning measures before and after the interventions/controls. The main hypothesis is that MAP will lead to memory-specific improvements above control conditions, whereas GMT will lead to greater improvements in measures of executive functions relative to controls.
A DIGITAL THERAPEUTIC TO IMPROVE THINKING IN MULTIPLE SCLEROSIS WHO: 65 participants with a confirmed diagnosis of Multiple Sclerosis (MS) WHY: Purpose of the study is to compare the effect of 2 tablet-based brain training digital tools on important components of thinking (cognition). WHAT: Complete a set of tests (physical and cognitive) at baseline, 6 weeks and 14 weeks, and use one of two brain training tools on an iPad in your home, for 25 minutes a day, 5 days a week, for 6 weeks. WHERE: UCSF WEILL INSTITUTE FOR NEUROSCIENCES (675 Nelson Rising Lane, San Francisco, CA)
The Overture Study is a randomized, controlled, single-blind multi-center clinical trial using the GammaSense Stimulation system to study safety, tolerability, and efficacy in people with mild to moderate cognitive impairment.
