NCT07327541
This study aims to evaluate the cognitive function, physical function, and pain levels of community-dwelling older adults to determine the impact of cognitive ability on physical function and pain. It also seeks to establish foundational data for strategies to prevent dementia and sarcopenia. Therefore, the purpose of this study is to measure the cognitive function (overall cognition, executive function, memory, attention, etc.), physical function (muscle mass, muscle strength, gait and balance ability), and pain of community-dwelling older adults, and to analyze the correlations between these factors.

Population ageing is associated with declines in motor and cognitive functions, which compromise autonomy and increase the risk of falls and cognitive impairment. Dual-task training programs have demonstrated additional benefits for physical and cognitive health compared with motor exercise alone. Aquatic environments provide unique advantages for older adults, facilitating movement execution and increasing adherence. However, evidence comparing aquatic dual-task training with conventional aquatic exercise remains scarce. This randomized, controlled, double-blind trial aims to compare the effects of an aquatic dual-task training program with those of a conventional aquatic exercise program on cognitive and motor functions in cognitively preserved older adults. Eighty-four participants aged 65 years or older were recruited, screened for eligibility, and randomly assigned to one of two groups: the Dual-Task Aquatic Group (n = 42) or the Conventional Aquatic Exercise Group (n = 42). The 12-week intervention consisted of two weekly sessions of 45 minutes. Cognitive (Montreal Cognitive Assessment; Mini-Mental State Examination) and motor outcomes (Timed Up and Go Test; Berg Balance Scale) were assessed pre- and post-intervention. Statistical analyses included intra- and inter-group comparisons using non-parametric tests, with a significance level of 5%. The dual-task group demonstrated significant improvements in balance, functional mobility, and cognitive performance, while the control group showed improvements only in motor outcomes. Between-group comparisons revealed superior cognitive gains in the dual-task group, with no differences in motor outcomes. Adherence exceeded 95% in both groups.
NCT07039708
A computer-based cognitive rehabilitation program based on daily tasks utilising the semantic encoding strategies called Enhancing Memory in Daily Life (E-MinD Life) has been developed for Chinese people. The aim of the E-MinD Life is to delay functional deterioration associated with possible cognitive changes in healthy older adults, older adults with memory complaints, mild cognitive impairment (MCI) and mild dementia. This project will pilot-test the E-MinD Life in Chinese healthy older adults, older adults with memory complaints, MCI and mild dementia.
NCT06838481
Normal aging leads to a decline in neuromuscular and mobility functions, including a 60% reduction in maximal voluntary force production, a 25% decrease in muscle volume and quality (sarcopenia), and reduced tendon stiffness by age 70. These changes impair walking speed, balance, and increase the metabolic cost of walking by \~20% in older adults compared to younger individuals. While walking training can reduce metabolic costs, no interventions have successfully addressed the 20% age-related difference. Resistance training, particularly eccentric (muscle-lengthening) training, shows promise for improving muscle strength and mass, but its effects on functional, cognitive abilities, and walking economy in older adults remain unexplored.
NCT04181983
Scientific Background: Despite the known health benefits of exercising during old age, older people remain highly sedentary. Official exercise guidelines aimed specifically at older people focus primarily on aerobic activity, and tend to be over generalized.There is need for personalized exercise programs, which account for the increasing variability in measures of fitness and mobility with advancing age, and offer exercises aimed at improving balance, strength, flexibility and aerobic fitness, and which can be performed at home. Advancing smartphone technology provides tools which might help address this important area of public health. Study Aims: To develop a novel digital smartphone app, which enables assessment of fitness components, and provides personalized comprehensive exercise programs which update at regular intervals according to changes in fitness levels. Methodology: A prospective interventional randomized control study involving 360 people aged ≥65 living at home/ sheltered living. Stage 1 will include selecting exercise and fitness tests, developing a smartphone app for self-assessment of these tests, and designing exercise programs to meet specific capabilities. A pilot study (n=60) will validate results from the app compared to standard laboratory tests, before finalizing the study platform, and will create a platform for matching exercise programs to levels of fitness. At Stage 2 - the main study - participants (n=300) will be randomly assigned to the intervention group (personalized updating exercise program via the app), an active control group (receiving World Health Organization (WHO) exercise guidelines), or control group (no intervention). Using the app for assessment, all participants will be tested during stage 2 at T0 (baseline), T1 (6 week) T2 (12 weeks), and during Stage 3 follow-up at T3 (18 weeks) and T4 (24 weeks). Novelty and Applicability: This innovative technology will enable older people to test their fitness level, and receive a personalized exercise program based on their current ability and preferences, which changes over time according to their progress. The program will be presented as photos and short videos, available on their smartphones, or easily transferable to computer or television (TV) screens.
NCT03430401
This study will adopt a newly developed computer-based cognitive rehabilitation program targeting the encoding stage of memory. The aims of the study are: 1. To test the feasibility of conducting a newly developed computer-based cognitive rehabilitation program for healthy older adults, people with MCI and mild dementia. 2. To test the effectiveness of the newly developed program in improving cognitive function and enabling maintenance of occupational performance in healthy older adults, people with MCI or mild dementia. Using an iPad application, study participants will learn a memory encoding strategy to support completion of their daily activities. By implementing memory encoding strategies during the mild stages of cognitive decline, the project aims to prolong independence in functional performance. It is anticipated that adoption of the same memory strategies will enable maintain performance as they may experience ongoing cognitive decline.
NCT03944603
This study plans to examine biological bases of cognitive aging. The goals of the study are to better understand how immune system markers, measured in the blood and in the spinal fluid, are related to clinical features of aging over time. The study also aims to better understand how different types of biomarkers may relate to immune health and the aging process. This research may ultimately help us better understand what puts individuals at risk for cognitive decline and for Alzheimer's disease.
NCT01888055
The aim of this study is to investigate whether the anodal transcranial direct current stimulation (tDCS) over the primary motor cortex (M1) in healthy older adults leads to an increase in cortical plasticity (change in motor evoked potentials (MEP) in mV).

Subjects are assessed using neuropsychological tests and then a mood induction task based on movie clips is applied.
NCT03197181
Motivation represents a core aspect of goal-directed behavior as it determines how much effort individuals are willing to invest to reach their goals. While research on effort-based decision-making focuses mainly on effort preferences in younger adults, loss of motivation might be a key component of the apathetic tendencies frequently seen in older adults. However, an open question refers to which brain mechanisms underlie motivational processes in older adults. The investigators have recently shown that the frontopolar cortex plays a crucial in motivating the exertion of rewarded effort in younger adults. The goal of the current study is to determine whether frontopolar cortex plays a crucial role for motivation also in older adults and may thus be a promising target for improving the motivation deficits in healthy aging. Participants perform computer-based experimental tasks measuring the propensity to exert cognitive or physical effort for monetary rewards. During task performance, participants receive anodal or sham transcranial direct current stimulation (tDCS) over their frontopolar cortex. The study tests whether tDCS over frontopolar cortex allows modulating participants' motivation to engage in rewarded effort.
