Filter by:The goal of this clinical trial is to compare the effects of taking a new supplement for 16 days on cognitive function and exercise performance, compared to a placebo (a supplement that looks and tastes the same, but doesn't have the same ingredients) in 40 healthy individuals - 20 young individuals (aged 18-30) and 20 older individuals (aged 50-65). The main questions it aims to answer are: - If taking the supplement for 16 days improves exercise performance, or the speed with which the body responds to the commencement of exercise. - If taking the supplement improves cognitive function. Participants will visit the lab on 5 separate occasions to: - complete some cognitive tests - complete exercise performance tests - provide blood samples All exercise tests will be on an exercise bike. After 28 (or 46 for pre-menopausal females) days to make sure the supplement has left the body fully, participants will consume the opposite supplement and repeat the tests.
The goal of this clinical trial is to understand the beneficial role of mindful walking in sustaining cognitive health in African American older adults who have elevated risk of developing neuropsychological diseases. The main question it aims to answer is "Does a multi-session mindful walking intervention lead to promising signals of sustaining cognitive health in vulnerable AA older adults?" The researchers in this 2-arm randomized controlled trial will compare the mindful walking group with a delayed mindful walking to see if the intervention efficacy is observed at multiple follow-up period.
Patients undergoing gastrointestinal tumor surgery are prone to delayed recovery and postoperative cognitive dysfunction due to greater trauma and longer operation time. Pre-analgesia can reverse the effects of nociceptive stimulation on recovery from general anesthesia and postoperative cognitive function. Intravenous injection of non-steroidal drugs can effectively reduce postoperative pain and the use of opioids. Therefore, This study selected acetaminophen mannitol injection for preemptive analgesia to observe the effects on anesthesia recovery time and postoperative cognitive function of patients undergoing gastrointestinal tumor surgery, providing new ideas for reducing cognitive dysfunction in patients undergoing gastrointestinal tumor surgery
While the association of physical and/or motor and/or cognitive components with training can generate synergistic effects and thus create an efficient cognitive enrichment program, very few studies have focused on finding an optimal combined program for older adults. According to the model of Herold and his colleagues, there are two modalities of simultaneous combined training: Thinking While Moving (TwM), when the additional cognitive task is not linked to the motor task, and Moving While Thinking (MwT), when the cognitive task is integrated into the motor task. They assume the latter approach is the most promising for improving cognitive reserve. Nevertheless, to the investigators' knowledge, only one study has compared these two modalities in older adults and none has broadened the question by comparing several MwT trainings. The goal of this interventional study will be to compare the cognitive, dual-task, and physical effects of 6 physical and/or cognitive programs in healthy but inactive older adults. The main questions it will aims to answer are: - Will the Moving While Thinking and Thinking While Moving programs have the same effects? - If they have different effects, which will be the best way to improve cognitive, dual-task, and physical functions? The study is being set up between 2023 and 2025 to compare the cognitive, dual- ask and physical effects of 6 programs (3 months, 2 sessions of 1 hour per week). Three experimental MwT programs will be studied: Immersive and interactive wall exergames (I2WE), Complex Cognitive and Motor Activities (2CMA), and exergames with Switch (EXER). They will be compared to an experimental TwM program of stationary bike simultaneous to the Switch (Video games + bike) and 2 control programs: inactive video games (VG) and stationary bike (BIKE). A control group (CON) will be also created. Cognitive, dual-task, and physical pre-tests (before the program), post-tests (after the program), and retention tests (3 months after the end of the program) will be realized to evaluate the effects of the programs.
The goal of this randomized, cross-over, single-site trial followed by an exploratory third intervention is to understand how indoor lighting affects different measures of brain health in older adults living in independent living residences. This is a community based study occurring in a local senior living facility. The main question this study aims to answer is: - How does the quality of ambient indoor lighting an older adult is exposed to affect measures of brain health, such as sleep quality, physical activity, cognitive function, and social engagement? Participants will be exposed to three different indoor lighting conditions for 4 weeks each while performing the following tasks: - Wear a smartwatch throughout the study to measure sleep quality and physical activity - Wear a small, wearable light sensor to measure light exposure during waking hours - Perform cognitive assessments throughout the study to detect any changes between each of the lighting conditions - Complete self-report of surveys to assess independence, social engagement, sleep quality, and mood Results from these tasks will be compared within and between subjects to assess whether the different lighting conditions affect these different measures of brain health.
To examine the effects of a 1-year cluster-randomized controlled intervention of MIND diet on cognitive function among 240 participants with mild cognitive function (MCI) aged 50 years and above from 4 communities.
This project will determine the short-term impact of a standing desk converter on: 1) objectively measured physical activity and posture levels, and 2) brain (cognition) and heart (blood pressure regulation) function. The main outcome is habitual activity patterns, assessed by the thigh-worn inclinometer (activPAL). All participants will be equipped with an activPAL and have their cardiovascular and cognitive function assessed at baseline and 4 weeks. Participants in the intervention group will use a standing desk converter for 4 weeks, while the wait-list control group will be encouraged to maintain their regular activity patterns. Researchers will compare the intervention and control groups to see if using the standing desk converter will increase standing time and lower sedentary time, improve cognition, and improve blood pressure regulation.
The global population is aging, and Taiwan has become an aging society. The aging population continues to rise. When the physical function and mental state of the elderly gradually decline, it is easy for the elderly to enter a state of physical weakness. Weakness is the decline in the reserve capacity of the physiological system. It is also related to geriatric syndrome, causing falls, hospitalization, disability, death, and increased medical costs, burden on primary caregivers, and reduced quality of life for the elderly. Physical exercise training has been considered to be an effective strategy to prevent and delay disability and frailty, so this study uses the Vivifrail program for the elderly. A family-based 12-week exercise program, including: resistance, strength, balance, flexibility and cardiorespiratory endurance exercise training, performed five days a week, at least 45-60 minutes each time, so that the elderly can exercise at home, It can also improve physical function and improve the quality of life. This study adopts a randomized controlled trial (RCT) with a one-group pretest-posttest design, with pre-frail and frail elderly as the research objects, and uses comprehensive assessment of the elderly to understand the physical function of the elderly Status, Vivifrail for the elderly was provided for abnormal physical function items, and post-test evaluation was carried out 4 weeks and 12 weeks after the intervention. In Taiwan, there is no research on Vivifrail for the frail elderly. In view of this, it is hoped that through the Vivifrail program and the follow-up of case managers, multi-faceted and continuous integrated care can be provided. Improve and maintain the physical function of the frail elderly for reference in the daily care of the elderly in the future.
Brief Summary: The study was conducted in two parts, the first of which was carried out using a cross-sectional design approach to explore the relationship between cognitive function and autonomic function, brain function, inflammation and oxidative stress, vascular function, fitness levels, cardiorespiratory endurance and lipid metabolism. The second part uses a repeated measures design approach in a randomised controlled design to explore the effects of different types of exercise on cognitive decline in postmenopausal hypertensive women and their mechanisms of action.
Tomatoes and tomato-based products could play an important role in modulating microbiota-gut-brain axis (MGBA) interactions due to their high content of fiber and phytochemicals. Phytochemical metabolites derived from the consumption of tomato-based products can act directly as neurotransmitters in the central nervous system, crossing the blood-brain barrier, or indirectly by modulating the MGBA. These metabolites can thus alter gut bacterial composition and brain biochemistry. Therefore, researchers propose a new interventional study to assess the impact of daily tomato consumption in the organism, and to evaluate the effect on the MGBA. The final aim of this study is to spread a message of the health benefits of tomato consumption for the general population.
