Filter by:The present study will evaluate the effects on glucose, ketones and other blood biomarkers, cognition, quality of life, physical activity and well-being of a reduced carbohydrate diet paired with a ketogenic product for 2 months in a population living in a senior residence. This study follows the KetoHome (fall 2022) and SAGE (fall 2023) projects which assessed the feasibility, acceptability and effectiveness of a reduced carbohydrate intervention alone.
In this study, a social media chatbot was used to provide a continuous and real-time multimedia health education program on physical activity for the older adults, as well as supportive messages and feedbacks, to improve physical activity and exercise self-efficacy among the older adults. This study was a cluster randomized trial, and participants were recruited from community care stations and activity centers in Taipei City. The experimental group was involved in an 8-week, 5-day-a-week intervention with a total of 40 multimedia physical activity education programs, and users were provided with real-time feedback interactions and regular physical activity education guidelines, and self-administered questionnaires were used for data collection. The research instruments include basic personal information, International Physical Activity Questionnaire, Exercise Self-Efficacy Scale, Behavioral regulation in exercise questionnaire-2, Exercise Benefits/Barriers Scale, and the statistical methods will be descriptive statistics, independent sample t-test, paired sample t-test, and one-way analysis of covariance.
The proposed research is relevant to public health because stroke is a leading cause of long-term disability among older adults and communication impairments resulting from stroke have a significant negative impact on quality of life. By seeking to better understand post-stroke aphasia, this project lays the groundwork for development of new interventions, and aligns with NIDCD's priority areas 1 (understanding normal function), 2 (understanding diseases), and 3 (improving diagnosis, treatment, and prevention).
Detecting memory problems early is crucial for treating conditions like Mild Cognitive Impairment (MCI), which often leads to dementia. Currently, doctors use tests in clinics to check for these issues. However, there's a growing need for better methods to monitor our cognitive skills over time. Computer games emerge as a cost-effective solution for assessing the brain functions of older adults. In our study, we are investigating the potential of computer games to reflect the cognitive skills of older adults. We developed the VibrantMinds platform, featuring five games: Whack-a-Mole, Bejeweled, Mahjong Solitaire, Word Search, and Memory Game. We have evaluated these games for ease of use, enjoyment, and their impact on brain functions. Now, our goal is to determine whether these games can offer valuable insights into the cognitive skills of older adults. We are collecting demographic data, game-playing data, and cognitive test results. Our analysis will determine the correlation between game data, cognitive test outcomes, and demographic information. Additionally, we will assess both the perceived and observed engagement of older adults as they play the games.
Time processing, the ability to process and encode temporal information, is essential for cognitive functioning and for a large number of daily life activities. In particular, the processing of durations of several seconds is central to cognition, impaired in several pathologies, and has been associated with cognitive changes with advancing age. While behavioral studies have been conducted to specify the neural bases of temporal cognition and their association with other cognitive functions, the mechanisms underlying age-related changes, and individual differences, remain unknown. The project will characterize ageing effects on timing mechanisms and their neural underpinnings. Building on recent advances from neuroscience and age-related cognitive changes, the project focuses on the precision of duration processing, that declines with age, and the associated neural bases. Participants will perform a duration judgement task while (a) electroencephalography, and (b) functional magnetic resonance imaging activity are simultaneously recorded to investigate age effects on structural and functional network connectivity. In addition, striatal dopamine will be measured using a FDOPA PETscan. Evaluation of other temporal cognition processes and general cognition will also be performed. This combination offers a unique opportunity to accurately specifying the neurophysiological underpinning of aging effects on time processing changes. This project will further our understanding of the variability of cognitive performance with advancing age, and contribute to identifying new measures of temporal impairments.
This study is a randomized, double-blind, placebo-controlled study of N=120 apparently healthy men and women. The purpose of this study is to assess the effect of a novel dietary supplement on blood markers of nutrient status, gut microbiome, and overall quality of life.
This research study is investigating whether people with Alzheimer's disease experience more changes to voice and swallowing than their healthy age-matched peers. The prevalence of swallowing impairments in moderate-severe Alzheimer's Disease is high (85-93%) and voice is also often negatively impacted by Alzheimer's disease. The overall objective of this study is to evaluate the voice and swallowing function of adults with and without Alzheimer's disease. The investigators will also be involving the primary caregivers of individuals with Alzheimer's that are enrolled in the study to better understand the impact of voice and swallowing impairments on the primary caregivers of those with Alzheimer's Disease. Healthy adults and individuals with Alzheimer's disease will: - undergo tests of cough, voice, and swallow function - undergo tests of grip and tongue strength - complete questionnaires Caregivers of individuals with Alzheimer's disease will also complete questionnaires.
This study is a randomized, double-blind, placebo-controlled study of N=16 apparently healthy men and women. The purpose of this study is to examine the bioavailability of a health and wellness supplement.
This study consists of three aims focused on examining the feasibility of adding the Geriatric Resources and Assessment for the Care of Elders (GRACE) model to structured Annual Wellness Visits (AWVs) to improve patient and caregiver outcomes and reduce hospitalizations in older adults with complex health needs. The objectives are to: 1. Co-design a community-centric implementation strategy for the AWVs vs AWVs + GRACE -augmented care (AWV GRACE) study arms 2. Develop a referral pathway and algorithm to optimize enrollment of eligible participants 3. Conduct a pilot clinical trial to assess the feasibility of the AWV GRACE intervention.
The aging population is growing rapidly. For the first time ever, Canadian seniors outnumbered young adults in 2016. Aging is associated with many physical and metabolic deteriorations including the loss of muscle mass and strength, insulin resistance, increased inflammation and oxidative stress. The muscles of our bodies are composed of proteins and proteins are made of small building blocks called amino acids. Our bodies have the ability to make some amino acids which are called the non-essential amino acids. However, there are certain amino acids that our body's need to make protein but can only be supplied from the foods that we consume. These are called essential amino acids. Tryptophan is one of the essential amino acids that the body needs. Tryptophan is required for protein synthesis and acts as a precursor for serotonin and nicotinic acid. Therefore, there may be a need for more threonine in the diet of older adults. However, the current requirement for threonine is based on studies conducted exclusively in young adults. Thus, the purpose of this study is to find out how much tryptophan older adults need.
