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.
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 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.
This study is to determine if an oral drug called Ramipril can lower the chance of memory loss in patients with glioblastoma getting chemoradiation. Patients will take Ramipril during chemoradiation and continue until 4 months post-treatment. Memory loss will be assessed using several neurocognitive tests throughout the duration of the study.
This study evaluates the feasibility of enrolling and retaining older adults in a 15-week intervention that will implement six factors from early childhood experiences: individualized scaffolding (having a responsive teacher), forgiving environment (allowing the learner to make and learn from mistakes), growth mindset (believing that abilities can develop with effort), open-minded learning (exploring new experiences), serious commitment to learning (adopting a "learning" lifestyle), and learning multiple skills simultaneously. These six factors will be implemented via concurrent classes at the UCR Extension center (OSHER Lifelong Learning Institute).
Among the most promising interventions targeting both cognitive and functional decline, is Exercise. However, evidence regarding exercise interventions among seniors with cognitive impairment are inconclusive, likely due to challenges of recruitment and adherence. Alternatively, seniors with subjective cognitive decline (SCD), who are not yet meeting objective criteria of cognitive impairment, but have been shown to have twice the conversion rate to dementia compared with healthy seniors, are more likely to be motivated to participate and adhere to exercise interventions. Thus, exercise interventions in seniors with SCD may provide a window of opportunity for early prevention of dementia and falls. The investigators aim to test the effect of a group exercise (multi-task Jaques-Dalcroze Eurhythmics) and a simple home strength exercise program on change of cognitive function and the rate of falling among seniors with SCD.
The project presented here respond to this emerging need by implementing a Reminiscence Therapy program dedicated to elderly people in an institutional context. This will be a multicenter, randomized controlled study in which the participants' allocation will be made without their knowledge. Before the randomization process, the screening evaluation will be done, which will allow to verify the presence of the inclusion and exclusion criteria. The target population will be people age 65 or above years who present cognitive decline. After the randomization process, participants will be allocated randomly in the experimental group where the reminiscence program (composed by a main strand and maintenance strand) or in the usual institutional care group. The evaluation of the participants will be carried out individually and will take place in four different moments.This study will be conducted in RSE in the central region of Portugal.
