Filter by:In developed countries, the acceleration of the general population ageing has been widely described for decades, involving changes in public health policies. Among the health issues arising from this demographic change, the maintenance of cognitive function will be a major challenge in the next years, both in societal and economic terms. In this regard, some pharmacological and behavioural (e.g. physical activity, social involvement, intellectually demanding activities) preventive approaches have been evaluated to improve cognitive function with ageing. Among them, dietary interventions showed a potential interest to prevent cognitive decline during ageing. In this sense, there is a growing interest to find ecological solutions and to meet major societal challenge the use of microalgae as molecule of interest sources is a recent promising approach. Marine environments harbour a huge biological diversity of microalgae that represents a large source of almost untapped bioactive compounds. This biodiversity comprises 200,000 to 2 million species with about 35,000 which are described and 15,000 maintained in culture collections. Microalgae are able to produce bioactive molecules, such as pigments, fatty acids, peptides and sterols. Some of these compounds are unique and specifically found in the marine environment and they could be increasingly used as natural bioactive products for targeted applications. Fucoxanthin is one of the major carotenoid found in microalgae well known for its neuroprotective effect but to our knowledge no human studies were realized. Thus the objective is to evaluate, in healthy older adults, the effect of a 24-week period of daily supplementation of high and low BrainPhyt, doses on cognitive function parameters (Spatial Working Memory scores, Attention and vigilance, episodic memory, executive function), stress, mood, sleep quality and biomarkers.
The primary objective of this study is to investigate the effects of strawberries on cognitive responses, motor control function, and vascular and cardiometabolic risk markers in healthy older adults.
Usability evaluation of BrightGo cognitive telerehabilitation system. An experimental system was developed to enhance standard of care (medication effect) for Early Alzheimer's Disease populations. This computerized system will be undergo a usability evaluation by healthy and by elderly participants who are in the early phase of Alzheimer's Disease. Sessions will and with participants filling subjective evaluation questionnaires as well as the USE standardized form. Results will be used to address any uncovered issues before a follow on Pilot RCT Feasibility study. Participants will receive $25 after each evaluation session.
Background: There is on one hand sufficient evidence showing strong association between resilience and self-rated successful aging. On the other hand, strength training could contribute the cultivation of resilience among older adults. Therefore, the current study aims to examine the effectiveness of resistance training on resilience among Chinese older adults in Hong Kong. Methods: This study will apply a three-group, double blinded (outcome assessors and data analysts), randomized controlled trial (RCT) to examine the effectiveness of the interventions on resilience, functional fitness, and health related quality of life immediately after a 16-week intervention, as well as the residual effects 12 weeks after completion of the interventions. Discussion: It is expected that resistance training is promising or even superior to aerobic training in the improvement of resilience. Given the limited evidence on the literature, it is urgently needed to explore the effects of resistance training on the improvement of resilience in older adults. Findings of the current study can contribute to the development of effective resistant training programs for the promotion of resilience among older adults.
30 healthy older participants were enrolled in the study and were randomly classified into two groups. In the experimental group (n = 15) participants received 10-week Tai Chi Chuan practice intervention, in the control group (n=15) participants were asked do not change their living habits in 10 weeks. All participants had no practice Tai Chi Chuan before.
The research is designed to answer effectiveness of community-based multimodal intervention programs on physical, mental, cognitive, social, and environmental in active and aging individuals.
The overarching goal of this pilot clinical trial is to use a novel virtual reality (VR)-based intervention that simultaneously engages physical and cognitive activity aimed at improving brain and cognitive outcomes in older adults. Physical activity is a promising lifestyle intervention for mitigating cognitive decline or delaying onset of dementia. However, to fully leverage beneficial brain effects of physical activity, training the brain to learn and engage in a cognitively stimulating environment may be the key to enhanced brain and cognitive outcomes.
Loss of independence, cognitive decline, and difficulties in everyday function are areas of great concern for older adults and their families. From a public health perspective, successful efforts that enable older adults to age within their homes, as compared to nursing homes, will save an estimated $80 billion dollars per year. Cognitive training is one intervention that maintains cognition, everyday function, and health. Although clearly an important and effective intervention, the mediators, or mechanisms, underlying this program are unknown. Our overall objective is to assess the cognitive and psychosocial factors within daily life that account for the transfer of one form of cognitive training to everyday function. This exploratory double-blind trial will randomize older adults to 20 hours of cognitive training or cognitively stimulating activities. The investigators will assess cognitive and psychosocial factors before, during, and after training within daily life. The investigators will then compare such factors and assess how they impact the transfer of cognitive training to everyday functioning. The investigators will also include an eligible sub group of the EFIT participants who will have functional MRI brain scans and sleep evaluation using the Sleep Profiler, a clinically approved device, at pre and post brain training. The investigators will also monitor daily activity in this sub group using FitBIt watches. Our central hypothesis is that improvements in daily processing speed and attention, key components of higher order cognitive functions, will have the strongest relationship with everyday function changes. This exploratory study is the first of its kind and will be used to provide important data relevant to a future larger randomized controlled trial examining mediators of cognitive training in a representative sample of adults. Additionally, all data collection, with the exception of MRI, can be completed remotely within the participant's home. This information will assist in the future development of more effective home- and community-based interventions that maintain everyday function.
Older people show deficits in dynamic weight-shifting, as the investigators found that more time is needed to perform weight-shifts and the movements became less fluent and accurate in older versus younger adults. Deficits with weight-shifting in the mediolateral (left-right) direction have been linked to balance and falls in ageing. Balance control can be improved with training. Virtual reality (VR) based training programs for improving balance are gaining ground, as it can provide both fun and challenging balance tasks, enhancing motivation. The investigators demonstrated earlier that older adults show an overloaded neural activation pattern compared to young adults when performing the same VR-based mediolateral weight-shifting task (wasp game). What is yet unclear, is whether improved balance capacity can be gained with training and whether such an intervention impacts the underlying neural mechanisms. Using a combination of behavioral assessments and functional Near-Infrared Spectrocopy (fNIRS), the primary aim of this study is to investigate the effects of a VR-based weight-shift training and its underlying neural imprint in older adults. Furthermore, as a previous study done by the investigators also showed that adding an extra cognitive task in a so-called dual-task (DT) negatively affects weight-shifting performance, a secondary aim will be to test whether weight-shift training will enhance performance during such DT conditions. The results of this study may contribute to the future design of technology-based rehabilitation programs.
