Filter by:This is a randomized, double-blind, placebo-controlled, 4-week intervention clinical study assessing the efficacy of Mirtoselect®, Virtiva® Plus, and Enovita® on cognitive performance and mood states, and the occurrence of adverse events in response to daily supplementation. The desired sample size for this study is 64 subjects. To account for potential dropouts, we aim to enroll up to 20% over the desired sample size. Therefore, this study will enroll up to 76 healthy men and women (25-55 years of age). Subjects will be randomly divided into four study groups: Placebo, Virtiva® ginkgo biloba extract, Mirtoselect® bilberry extract, or Enovita® grape seed extract. Blocked randomization will be deployed in which subjects are divided into blocks of 4 subjects and each subject within a block is randomly assigned to one of the four study groups.
The proposed project aims to develop and validate a multi-dimensional digital active aging program integrated with resilience to promote the biopsychosocial functions of older adults aged 60, including Chinese older immigrants in Canada (Study 1) and English-speaking White Canadian older adults (Study 2). The proposed study takes a typical pretest-training-posttest design. Pretest and posttest: a battery of outcome measures on physical, psychological, and social functions will be administered to all participants. Data will also be used to identify sociodemographic risk predictors for outcome variables (i.e., biopsychosocial functions and resilience). Training: the participants will be randomly assigned to three arms to receive 4 weeks of 16 training/practice/control treatment sessions delivered via Zoom. In the "active aging with resilience (AR)" condition, participants will complete physical, cognitive, and social engagement training modules, starting with a 30-min resilience-building module. The traditional "active aging" (AA) training involves the same multi-domain active aging training without the initial resilience-building module. The "workshop training" (WT) control condition involves workshops following the same 4-week schedule on aging-related topics.
This study will investigate the biological mechanisms linking sleep disruption by vibration and noise, and the development of cardiometabolic disease. In a laboratory sleep study, the investigators will play railway vibration of different levels during the night. The investigators will also measure objective sleep quality and quantity, cognitive performance across multiple domains, self-reported sleep and wellbeing outcomes, and blood samples. Blood samples will be analyzed to identify metabolic changes and indicators of diabetes risk in different nights. Identifying biomarkers that are impacted by sleep fragmentation will establish the currently unclear pathways by which railway vibration exposure at night can lead to the development of diseases in the long term, especially metabolic disorders including diabetes.
The goal of clinical trial is to learn about how blood pressure fluctuations affect cognitive performance (thinking abilities) and brain blood flow in persons with Parkinson's disease with and without orthostatic hypotension (low blood pressure when standing). The main questions it aims to answer are: - Is there a certain level of blood pressure that correlates with change in cognitive performance while upright? - Is there a certain level of change in brain blood flow that correlates with change in cognitive performance when upright? - How does cognitive performance differ between persons with Parkinson's disease that have orthostatic hypotension and those without orthostatic hypotension? - How does cognitive performance differ between the supine (laying down) and upright positions? - How do blood pressure and brain blood predict changes in cognitive performance over two years? Participants in this study will undergo the following procedures: - Complete a screening visit with questionnaires, medical history, physical exam, and head-up tilt-table test. - Attend one baseline study visit, during which they will undergo a battery of computerized cognitive tests repeated twice: once while laying down and once while upright on a tilt table. Simultaneously, during the experiments we will measure blood pressure using a wrist-worn device and inflatable arm cuff and will measure brain blood flow using functional near-infrared spectroscopy (fNIRS), a non-invasive device that uses light sensors to detect changes in brain blood flow. - Attend one two-year follow-up visit, during which they will repeat a battery of computerized cognitive tests repeated twice: once while laying down and once while upright on a tilt table. During this visit, like before, we will measure blood pressure using a wrist-worn device and inflatable arm cuff and will measure brain blood flow using functional near-infrared spectroscopy (fNIRS). Researchers will compare participants with Parkinson's disease with and without orthostatic hypotension in the laying down and upright positions to see if there are changes in thinking abilities between these groups.
The current project is dedicated to creating a comprehensive cognitive and neural assessment platform and corresponding norms tailored specifically to the older adults in Macau.
This research project will develop and implement a motivational interviewing and electronic messaging intervention to address obstructive sleep apnea (OSA), positive airway pressure (PAP) adherence, and risk of Alzheimer's disease and related dementias in American Indians. The project will work with American Indian Elders, aged 50 years and older, from three Northern Plains Reservations and surrounding communities. A total of 300 American Indian elders with a confirmed OSA diagnosis and prescribed PAP therapy will be randomized to receive usual care consisting of PAP therapy alone (control condition) or usual care plus the culturally informed CATNAP MI component (intervention condition).
This study will compare the impact of a novel high-speed, cued yoga program to a standard yoga program on retinal microvasculature, cognition and neuromuscular function in persons with Parkinson's disease.
Previous studies in young adults have shown that physical activity can generate positive emotions and improve attention, among other cognitive functions. This highlights the importance of evaluating how physical activity can affect cognition and affective dimensions. However, to date, the dose of physical activity that could be most effective for these variables has not been established. This project aims to study the impact of acute physical activity on brain health in a university setting. Thus, this study will contribute to expand the current scientific literature on the acute effect of physical activity, a topic of great importance both in the educational field and from a public health point of view.
The goal of this interventional clinical trial is to test the effectiveness of improving cognitive development in newly born infants fed with Feihe investigational formula product containing HMO, and DHA/ARA. The main question it aims to answer is: - whether the score of Bayley-III cognitive scale (tested at the age of 12 months) of participants in the study product arm is significantly better than participants assigned in the other two arms. 240 qualified participants will be randomized to 3 arms (investigational formula, control formula, and breast-feeding) to consume assigned formula or breast-feeding for 12 months according to protocol. There will be up to 6 site visits arranged for each participant during the study, and all relevant clinical and questionnaire data, including the most important Barley-III cognitive scale data at the age of 12 months, will be captured, recorded and entered to CMTS (Clinical Management Trial System) for statistical analysis and reporting. Researchers will compare the three arms to validate the assumption that the consumption of Feihe investigational formula product containing HMO, and DHA/ARA will improve cognitive development in newly born infants, along with physical development.
The Interventions for Brain Health Virtual Reality Study is a NIH-funded clinical research trial at the University of California San Diego (UCSD) Health under the supervision of the study principal investigator Dr. Judy Pa. The overarching goal of this trial is to use a novel virtual reality (VR) based intervention that simultaneously engages physical and cognitive activity aimed at improving brain health and cognition in older adults. The investigators will compare 3 types of interventions: physical activity, VR cognitive activity, and combined VR physical and cognitive activity over 16 weeks to evaluate physical and brain health changes.
