Filter by:Individuals of advanced age are at higher risk of cognitive deterioration.A single bout of aerobic exercise was found to improve cognitive functions. The aim of this study is to explore the effect of a single bout of balance and coordination exercise versus aerobic exercise on cognitive functions among elderly people.
Advanced age is the main risk factor for chronic diseases such as cardiovascular disease, type 2 diabetes, Alzheimer's disease and cancer. One reason may be due to decreased resistance to oxidative stress as antioxidant defenses and cell protection is reduced with aging. This has been shown in animal studies and also that the impairment can be somewhat restored with exercise. This will be the first study to test this in humans by comparing young and older inactive adults before and after an exercise intervention, a practical and cost-effective intervention that can have tremendous public health impact by lowering risk for disease and medical-related costs.
Objective: The study aims to understand the physical function, body composition, mental state, behavior, depression, and life quality change of the elderly in a long-term care before and after the intervention. Four interventional activities are sitting strength training, games, sitting strength training with games, and health education.
Cognition encompasses memory, attention, language and other brain capacities that are necessary for good quality of life and independence. Age-related cognitive decline starts at the third decade of life and in some cases can start to impact daily functioning in the late forties. Dementia is the most devastating consequence associated with age-related cognitive decline. Recent studies indicate that improving cognition by means of intensive computerized brain training can mitigate some aspects of agerelated cognitive decline, and may even have a role in preventing or delaying dementia onset. Critically, the capacity of a given individual to improve their cognitive performance after training is fundamentally related to engagement with the exercises. Currently, little is known about how to apply intensive computerized cognitive training effectively in the health system, ensuring engagement and best progress. This project aims to tackle this challenge by developing, applying and testing personalized approaches to implement cognitive training in daily life of older adults that were recently evaluated at Memory Clinics and their care partners. The community readiness approach will be implemented using semi-structured interviews, conducted with subjects that may be interested in cognitive training, key informant, and key stakeholders. Using this information, the investigators will design an individualized training program and follow up its application in a feasibility trial. Twenty participants, recently evaluated at different Memory Clinics in Ireland, will be recruited, interviewed and invited to engage, over the ensuing 2 to 3 months, in computerized cognitive training. Subjects will be assessed after completion of the intervention for training adherence and individual gains on the computerized exercises. In order to gain insight about regional specificities of the approach the investigators will perform a parallel project using the same methodology in Brazil. This project is expected to inform the future implementation of cognitive training in public health policies for older adults.
The goal of this study is to evaluate the effect of white matter guided theta burst stimulation on episodic memory task performance in healthy older adults. The investigators aim to propagate the effect of theta burst stimulation from a superficial locus of stimulation (angular gyrus) to hippocampus and parahippocampal regions using white matter tract connection between these regions. Study activities and population group - for the study plans to recruit 20 healthy older adults who already have white matter scans acquired as part of another study performed by the Cabeza Lab at Duke University. Using tractography the exact site of stimulation on the cortical surface will be localized. An initial motor evoked potential (MEP) assessment will differentiate responders to theta burst stimulation from non responders. Responders will receive 1200 pulses of intermittent theta burst stimulation (iTBS) or sham stimulation to the angular gyrus while they perform the encoding portion of an episodic memory task. There after, they will perform retrieval piece of the task and data analysis will compare these performances.
This is a randomized controlled trial. The present study involves an acute and chronic intervention, which is a water-based exercise (one session: to acute intervention; 12-weeks of aquatic exercise program: to chronic intervention). The sample will be composed by elderly enrolled in university extension program titled "Hidroginastica na Terceira Idade" (Hydrogymnastics in aging). It will be evaluated the effects of water-based exercise on hemodynamics, self-reported sleep quality, depressive symptoms, quality of life, body composition, level of physical activity and functional capacity. The investigators hypothesized that an acute water-based exercise under different intensities promotes hemodynamics changes in elderly. In addition, the investigators hypothesized that 12-weeks of aquatic exercise may lead improvements in self-reported sleep quality, depressive symptoms, quality of life, body composition, level of physical activity and functional capacity in elderly.
The purpose of this study is to investigate the effect of cognitive rehabilitation program on the improvement of cognitive functions in normal elderly subjects.
This study will determine the short-term postprandial effects of protein source at breakfast on energy metabolism, markers of metabolic health, appetite, and food intake and young and older men.
The study objective was to determine the safety and efficacy of aerobic exercise in older HIV-infected men in a randomized trial comparing different levels of exercise intensity.
The Health Teams Advancing Patient Experience: Strengthening Quality (Health TAPESTRY) is a community-based program led by primary care teams, that creates connections between trained community volunteers, interprofessional health care teams, novel technology and community engagement through improved system navigation. The overall vision is to help people stay healthier for longer in the places where they live.
