Effects of natural reduced water on cognitive functions in older adults: A RCT study

Oxidative stress and diabetes increase the risk of cognitive decline and dementia. Natural reduced water contains active hydrogen (hydrogen radicals), eliminates reactive oxygen species, and has antidiabetic effects. However, whether natural reduced water affects human cognitive function is unknown. Therefore, we implemented a double-blind intervention experiment in which participants consumed 1 L of natural reduced water or tap water daily for 6 months. The participants were healthy older adults living in Japan. The intervention group showed significant improvements in cognitive functions of attention function (p < 0.01) and short-term memory (p < 0.05). These results indicate that the continuous intake of natural reduced water improves several cognitive functions.

The mediating role of individual evaluation, anxiety, and depression in the association between leisure activity and cognitive function among Chinese older adults.

The purpose of this research was to investigate the association between leisure activity and cognitive function in Chinese older adults, and to explore the mediating role of individual evaluation, anxiety and depression. Using cross-sectional data from the 2018 Chinese Longitudinal Healthy Longevity Survey (CLHLS), Pearson correlation analyses were employed to examine the relationships among various indicators. A multiple mediation model was constructed to investigate the mediating pathways through which leisure activities impact cognitive function in elderly individuals. Leisure activities, individual evaluation, anxiety, and depression were significantly correlated with cognitive function (p < 0.01). Leisure activities not only directly positively impacted cognitive function in elderly individuals (effect = 0.3780; 95% CI = [0.3459, 0.4101]), but also exerted indirect effects through five pathways. Individual evaluation, anxiety, depression, they plays a mediating role in the association between leisure activity and cognitive function in older adults in China. Leisure activities can positively impact cognitive function in elderly individuals by enhancing individual evaluation and subsequently reducing anxiety and depression.

The relationship between cognitive function and physical activity, functional status and social participation in older adults: a cross-sectional study

Aims: Cognitive function in older adults has been a topic of growing interest in recent years. This study aimed to investigate the relationship between cognitive function and physical activity, functional status, and social participation in older adults. Methods: A cross-sectional study was conducted involving 123 older adults aged 65 years and older who met the study’s inclusion criteria. The inclusion criteria for the study were as follows: who were aged 65 years or older, literate, volunteering to participate in the study, had no hearing or vision defects that prevented the measurement of the scales used in the study, had no chronic disease that prevented the scales used in the study. The data in the study were collected with sociodemographic form, Montreal cognitive assessment, international physical activity questionnaire, timed-up-and-go test, 10-meter walk test, and Keele assessment of participation. Results: The average age of the participants was 69.5±4.6. The study included 46.3% women and, 57.7% primary school graduates. A positive and moderate relationship was found between cognitive functions and physical activity level, functional status, and social participation in older adults. Additionally, there was a moderate positive relationship found between the level of physical activity, functional status, and social participation. In the cognitive function risk model, it was found that age, education level, and social participation significantly impact cognitive functions in older adults. Conclusion: Increasing physical activity, functionality, and especially social participation in older adults can be considered an important intervention to protect and improve the cognitive functions of older adults.

Assessing rapid spatial working memory in community-living older adults in a virtual adaptation of the rodent water maze paradigm

Aging often leads to a decline in various cognitive domains, potentially contributing to spatial navigation challenges among older individuals. While the Morris water maze is a common tool in rodents research for evaluating allocentric spatial memory function, its translation to studying aging in humans, particularly its association with hippocampal dysfunction, has predominantly focused on spatial reference memory assessments. This study expanded the adaptation of the Morris water maze for older adults to assess flexible, rapid, one-trial working memory. This adaptation involved a spatial search task guided by allocentric cues within a 3-D virtual reality (VR) environment. The sensitivity of this approach to aging was examined in 146 community-living adults from three Chinese cities, categorized into three age groups. Significant performance deficits were observed in participants over 60 years old compared to younger adults aged between 18 and 43. However, interpreting these findings was complicated by factors such as psychomotor slowness and potential variations in task engagement, except during the probe tests. Notably, the transition from the 60 s to the 70 s was not associated with a substantial deterioration of performance. A distinction only emerged when the pattern of spatial search over the entire maze was examined in the probe tests when the target location was never revealed. The VR task's sensitivity to overall cognitive function in older adults was reinforced by the correlation between Montreal Cognitive Assessment (MoCA) scores and probe test performance, demonstrating up to 17 % shared variance beyond that predicted by chronological age alone. In conclusion, while implementing a VR-based adaptation of rodent water maze paradigms in older adults was feasible, our experience highlighted specific interpretative challenges that must be addressed before such a test can effectively supplement traditional cognitive assessment tools in evaluating age-related cognitive decline.

The acute effects of coffee ingestion on postural control and physical function in older adults: A randomised crossover trial

Caffeine consumption can elicit improvements in aspects of physical function in older adults but also, negatively modify standing balance, potentially increasing fall risk. However, balance alterations and changes in physical function induced by commonly consumed caffeine vehicles such as coffee have not been investigated. Therefore, this study investigated coffee ingestion providing 3 mg·kg BW−1 caffeine on balance performance and physical function, in a group of older adults. In a randomised, crossover design, 22 older adults (Male n = 10, Age: 68 ± 6 years) completed bipedal standing balance and physical function assessments (Senior Fitness Test) under one of the following conditions: caffeinated coffee (COF), decaffeinated coffee (DEC), placebo (PLA) or a control (CON) (no fluid ingestion). Centre of pressure (COP) root mean square and power frequency were calculated to characterise postural performance and strategy, respectively. The complexity (i.e., regularity) of the COP signal was also determined by calculating sample entropy. Caffeinated coffee had limited effects on COP outcomes. Frequency of the COP in the anteroposterior direction was greater following COF compared to DEC (P = 0.047;g = 0.29) but there were no statistical differences between COF and PLA or CON (P > 0.05). Furthermore, there were no significant performance differences between any conditions in all tests of physical function (P > 0.05). This suggests that coffee has limited effects on balance performance or physical function but may influence both balance complexity and the strategy utilised to maintain upright stance. Overall, a strong cup of coffee does not significantly influence balance and measures of functional performance in healthy older adults.

NT-proBNP and Cardiac Troponin I, but Not Cardiac Troponin T, Are Associated With 7-Year Changes in Cardiac Structure and Function in Older Adults: The ARIC Study.

Higher circulating concentrations of NT-proBNP (N-terminal pro-B-type natriuretic peptide) and high-sensitivity cardiac troponin T (hs-cTnT) and I (hs-cTnI) are associated with left ventricular remodeling and with incident heart failure. The associations of these cardiac biomarkers with changes in cardiac structure and function over time are uncharacterized. Among 2006 participants in the ARIC prospective cohort study (Atherosclerosis Risk in Communities) who were free of overt cardiovascular disease and underwent echocardiography at study visits 5 (2011- 2013) and 7 (2018-2019), we assessed the associations of NT-proBNP, hs-cTnT, and hs-cTnI concentrations at visit 5 with changes in left ventricular structure and function between visits 5 and 7 (≈7-year change) using multivariable linear regression with the biomarkers modeled as restricted cubic splines. Models were adjusted for age, sex, race, body mass index, smoking, diabetes, hypertension, and renal function at visit 5; blood pressure and heart rate at both visits; and the baseline value of the echocardiographic parameter of interest. Mean±SD age was 74±4 years at visit 5; 61% were women; and 23% were Black adults. Median (25th-75th percentile) concentrations at visit 5 of NT-proBNP, hs-cTnT, and hs-cTnI were 87 ng/L (50-157 ng/L), 9 ng/L (6-12 ng/L), and 2.6 ng/L (1.9-3.9 ng/L). In adjusted models, elevated baseline concentrations of NT-proBNP and hs-cTnI were significantly associated with 7-year decline in left ventricular systolic function (ejection fraction, longitudinal and circumferential strain) and worsening diastolic indices. In contrast, elevated baseline concentrations of hs-cTnT were not significantly associated with 7-year changes in cardiac structure, systolic function, or diastolic function (all P>0.05). Higher concentrations of NT-proBNP and hs-cTnI, but not hs-cTnT, were associated with greater declines in left ventricular function over ≈7 years in late life independently of traditional cardiovascular risk factors.AQ.

Prevalence of Unwanted Loneliness and Associated Factors in People over 65 Years of Age in a Health Area of the Region of Murcia, Spain: HELPeN Project.

Background/Objectives: Population aging poses many challenges to public health, highlighting loneliness and social isolation as severe problems that affect the physical and mental health of older adults. During the COVID-19 pandemic, these became aggravated. The objective of the present study was to assess the prevalence of loneliness and its relationship with social isolation, depression, cognitive deterioration, sleep quality, and the level of physical mobility and functioning of older adults in Health Area 3 of the Region of Murcia. Methods: A descriptive, observational, and cross-sectional study was performed. The inclusion criteria were age ≥ 65, living in Health Area 3 of the Region of Murcia, and not being institutionalized. The following variables were evaluated: sociodemographic variables, loneliness (UCLA scale), social isolation (DUFSS), depression (GDS), cognitive deterioration (Pfeiffer), sleep quality (PSQI), and mobility (Barthel index). A univariate and multivariate regression model was created to examine how the dependent variable was related to the independent variables. Results: A total of 102 older adults participated in the study. Of these, 31.4% perceived unwanted loneliness and 14.7% low social support. The multivariate regression analysis showed that social isolation, geriatric depression, and cognitive deterioration were significant predictors of loneliness. Conclusions: The findings highlight the importance of developing multifaceted interventions that address not only social isolation but also other interrelated factors such as depression, cognitive deterioration, and sleep quality. The strategies should be centered on community programs and support networks. It is fundamental to perform longitudinal studies to better understand the causal relationships between these variables.

Correlation between Vegetable and Fruit Intake and Cognitive Function in Older Adults: A Cross-Sectional Study in Chongqing, China.

To explore the correlation between different types of vegetable and fruit intake and cognitive function among the older adults in Chongqing, China, and to provide a scientific basis for developing efficient lifestyle interventions for the prevention of Mild Cognitive Impairment (MCI). Approximately 728 older adults in urban and rural areas of Chongqing were surveyed using face-to-face questionnaires. Cognitive function was assessed with the Montreal Cognitive Assessment-Basic (MoCA-B) scale, and the vegetable and fruit intake groups were investigated with the Simple Food Frequency Counting Survey Scale. Binary logistic regression was used to explore the effect of the vegetable and fruit intake group on cognitive function. Subgroup analysis was used to demonstrate the robustness of the results. Of the 728 participants in the study, 36.40% were likely to have MCI, which is higher than the national average for this condition. After adjusting for confounders, compared to the Q1 group, fruit and root vegetable intake was a protective factor for MCI, showing a dose-response relationship (p < 0.05). Only lower intake (Q2) of total vegetables, medium intake (Q2, Q3) of solanaceous vegetables, and medium-high intake (Q2, Q4) of fungi and algae was protective against MCI, whereas the leafy vegetables showed no relation to MCI. Apart from this, participants who were older, female, unmarried, non-smoking, and engaged in physical labor, and who had an average monthly income of less than 3000 RMB were more likely to suffer from cognitive impairment. This suggested that the fruit-intake groups and some vegetable-intake groups showed a protective effect on cognitive function, and might behave differently depending on their different intake and demographic characteristics. A sensible, healthy diet can help prevent MCI.

Cardiorespiratory fitness, independent of APOE genotype, is associated with better neurocognitive function in older adults: An ERP study

This study assessed the association between cardiorespiratory fitness and carriage of the apolipoprotein-E ε4 (APOE ε4) alleles and cognitive function using behavioral and neuroelectric measures obtained from cognitively normal older adults. A total of 159 adults aged 50–70 years were categorized into four groups based on cardiorespiratory fitness (i.e., higher vs. lower fitness) and the APOE genotype status (i.e., APOE ε4 carrier vs. non-carrier). Neurocognitive functions were indexed using response time and accuracy measures from the Stroop task and averaged mean P3 amplitudes of event-related potentials obtained during task performance. A significant main effect of cardiorespiratory fitness (p = .01) and the Stroop congruency (p < .001), but not the APOE genotype status, with shorter response times for the higher fitness group than for the lower fitness group and for the congruent condition relative to the incongruent condition, were observed. Similar findings were also revealed, with larger averaged mean P3 amplitudes for the higher fitness group than those in the lower fitness group, and in the congruent condition than in the incongruent condition. These findings suggest that higher cardiorespiratory fitness is linked to better neurocognitive function, and the positive association is evident regardless of the APOE ε4 status and the cognitive domain assessed in cognitively normal older adults.

Comorbidities, medications, depression, and physical performance measures associated with severe cognitive impairments in community-dwelling adults

Cognitive impairment negatively impacts health, psychological, social, and economic domains. Cognitive impairment commonly affects physical functions in older adults, whereas these are deteriorated. However, the prevalence and associated factors of cognitive impairment among community-dwelling adults in Saudi Arabia have not been investigated yet. This study aimed to examine the prevalence of severe cognitive impairment and its associated factors in community-dwelling older adults in Saudi Arabia. This cross-sectional study involved adults aged ≥50 years. Demographic data and clinical data, including number of medications and body mass index (BMI), were collected. Cognitive impairment and depressive symptoms were measured using Arabic versions of the Montreal Cognitive Assessment (MoCA) and Patient Health Questionnaire-9 (PHQ-9), respectively. The participants were divided into severe cognitive impairment and mild cognitive impairment or normal cognitive function groups based on a score of &lt;20 or ≥20, respectively, using the MoCA. Physical measures included dynamic gait index (DGI) scores, timed up-and-go (TUG), 5 times sit-to-stand (5XSST), functional reach test, and 6-minute walk test. A total of 206 participants (female: n = 96) were included. The prevalence of severe cognitive impairment in the community-dwelling older adults was 12.6%. The number of chronic conditions (odds ratio [OR]: 2.31, p&lt;0.001), number of medications (OR: 1.36, p = 0.003), and depressive symptoms using PHQ-9 (OR: 1.11, p = 0.009) were significantly associated with severe cognitive impairment after adjustment for other covariates, including age, sex, and BMI. Based on the physical function measures, only the scores for DGI (OR: 0.86, p = 0.003), TUG (OR: 1.16, p = 0.035) and 5XSST (OR: 1.25, p &lt;0.001) were significantly associated with severe cognitive impairment. This study revealed a high prevalence of severe cognitive impairment among community-dwelling adults in Saudi Arabia. Its major risk factors include depressive symptoms, number of chronic conditions and medications, and physical measures, including DGI, TUG, and 5XSST.

Determinants of cerebral blood flow and arterial transit time in healthy older adults.

Cerebral blood flow (CBF) and arterial transit time (ATT), markers of brain vascular health, worsen with age. The primary aim of this cross-sectional study was to identify modifiable determinants of CBF and ATT in healthy older adults (n = 78, aged 60-81 years). Associations between cardiorespiratory fitness and CBF or ATT were of particular interest because the impact of cardiorespiratory fitness is not clear within existing literature. Secondly, this study assessed whether CBF or ATT relate to cognitive function in older adults. Multiple post-labelling delay pseudo-continuous arterial spin labelling estimated resting CBF and ATT in grey matter. Results from multiple linear regressions found higher BMI was associated with lower global CBF (β = -0.35, P = 0.008) and a longer global ATT (β = 0.30, P = 0.017), global ATT lengthened with increasing age (β = 0.43, P = 0.004), and higher cardiorespiratory fitness was associated with longer ATT in parietal (β = 0.44, P = 0.004) and occipital (β = 0.45, P = 0.003) regions. Global or regional CBF or ATT were not associated with processing speed, working memory, or attention. In conclusion, preventing excessive weight gain may help attenuate age-related declines in brain vascular health. ATT may be more sensitive to age-related decline than CBF, and therefore useful for early detection and management of cerebrovascular impairment. Finally, cardiorespiratory fitness appears to have little effect on CBF but may induce longer ATT in specific regions.

Exploring the impact of adverse childhood experiences on health and cognitive functions in older adults.

This study examines whether adverse childhood experiences (ACEs) predict long-term health issues and how ACEs, alongside stress, impact well-being and cognitive abilities in older adults. 279 adults were categorized into three age groups (30-46, 47-60, and 61-80). Participants completed an online survey assessing health problems, stress, resilience, and ACEs. Additionally, 32 older adults underwent cognitive tests. ACE scores predicted physical and psychological diseases in adults but not in older adults. However, a significant correlation between ACEs and cognitive abilities was evident in older participants. ACEs are significant indicators of long-term health issues and stress in adults but may not predict these factors in older individuals. Understanding ACEs' impact on cognitive abilities in older adults is crucial for tailored interventions and support.

Coping patterns associations with cognitive function in older adults.

Cognitive function may contribute to variability in older adults' ability to cope with chronic stress; however, limited research has evaluated this relationship. This study investigated the relationship between theoretically derived coping domains and cognitive function in 165 middle-to-older adults during the Omicron stage of COVID-19. Participants completed a clinical interview and self-report measures of health. The National Alzheimer's Coordinating Center Uniform Data Set neuropsychological battery was used to evaluate memory, language, executive function/speed, and working memory. Structural equation modeling evaluated the underlying factor structure of the Brief COPE adapted for COVID-19. The data supported the proposed second-order Approach factor comprised of Problem-Solving and Emotion Regulation (ER) strategies and a first-order Avoidance factor. Higher Avoidance was associated with greater depression symptoms, lower income and worse memory, executive function, working memory, and verbal fluency performance. Higher Problem-Solving was associated with better verbal fluency performance. ER strategies were not significantly associated with cognitive function. The use of Problem-Solving was not associated with less Avoidance. Greater use of Problem-Solving, ER, and Avoidance were all associated with higher levels of stress. Post-hoc analyses found that higher Acceptance was the only coping strategy associated with less stress. These findings demonstrate that older adults with worse cognitive function were more likely to use Avoidance during the pandemic, which could result in prolonged stress and adverse health consequences. Future research is warranted to investigate whether acceptance-based interventions reduce the avoidance and impact of stress on health in vulnerable older adults.

A 24-Week Combined Resistance and Balance Training Program Improves Physical Function in Older Adults: A Randomized Controlled Trial.

Jiang, G, Tan, X, Zou, J, and Wu, X. A 24-week combined resistance and balance training program improves physical function in older adults: a randomized controlled trial. J Strength Cond Res 39(1): e62-e69, 2025-This randomized controlled trial assessed the feasibility of older adults performing combined resistance and balance training (RBT) and compared the effects of RBT on physical function with those of resistance training (RT) alone and with no exercise training in older adults. In total, 65 community-dwelling adults aged 60-74 years were randomly assigned to an RT (n = 22), RBT (n = 22), or control (n = 21) group. The exercise intervention consisted of RT or RBT for 45 minutes, 3 times per week for 24 weeks. The control group engaged in no exercise training. The compliance rates were 93% in the RT group and 92% in the RBT group. No training-related adverse effect was observed. In the RT and RBT groups, dynamic balance (p = 0.017; p < 0.001, respectively), maximum walking speed (p = 0.014; p < 0.001), upper extremity (p = 0.013; p = 0.009) and lower extremity (p = 0.009; p < 0.001) muscle strength, and spirometry (p = 0.043; p = 0.018) were significantly improved at 24 weeks compared with the control group. Only the RBT group showed significant improvement in normal walking speed (p = 0.002). Compared with the RT group, the RBT group showed additional significant improvements in dynamic balance (p = 0.001) and lower limb muscle strength (p = 0.027). The findings of this randomized controlled trial indicated that RBT was safe and feasible for older adults. Long-term RBT had better effects than either no exercise training or RT alone on improving physical function in older adults. Compared with RT, RBT additionally benefited dynamic balance and lower limb muscle function, which are clinically important factors in preventing falls, frailty, disability, and other geriatric syndromes.

A - 85 Age-Related Differences in Cognitive Mechanisms: Exploring the Role of Processing Speed in Working Memory and Prospective Memory

Abstract Objective Research links working memory (WM) and prospective memory (PM) on cognitively demanding tasks. Older adults demonstrate more frontal lobe activation than young adults during WM and PM tasks; however, the underlying mechanisms remain unclear. The current study hypothesized processing speed (PS) as a mediator between WM and PM with age cohort as a possible moderator. Method Healthy older adults (n = 80; age 60–89, M = 72.51, SD = 7.08) and young adults (n = 63; age 18–29, M = 19.27, SD = 2.12) were administered WAIS-IV Digit Span, WAIS-IV Coding, and the Virtual Kitchen Protocol for Prospective Memory. Results A moderated mediation model revealed that WM positively influenced PM (c:B = 0.69, p &amp;lt; 0.001) with a positive indirect relationship through PS among older adults (ab:B = 0.26, 95% CI [0.13, 0.43]), but not young adults (ab:B = −0.08, 95% CI [−0.19, 0.03]). Conclusion PS appears to play a significant role in older adults’ use of WM for PM but not in young adults. This could suggest that older adults recruit additional cognitive resources – those involved in PS – as a compensatory strategy for real-world PM tasks, which would support prior research indicating that diminished functioning in older adults results from reduced ability to redirect neurocognitive networks. Alternatively, age-related declines in PS could be a root cause underlying both worse WM and worse PM in older adults, as postulated by Salthouse. Future research would benefit from further differentiating the direction of influences between WM, PS, and PM in older adults.

Influence of auditory-based cognitive training on auditory resolution, executive function, and working memory skills in individuals with mild cognitive impairment – a pilot randomized controlled study

Background Age-related central auditory processing disorder and mild cognitive impairment (MCI) can be concomitant in older adults, making it difficult to communicate, especially in challenging listening conditions. This preliminary study investigated the efficacy of auditory-based cognitive training on the auditory processing abilities and cognitive functions of older adults with MCI. Methods In this randomized controlled trial twenty-two older adults with mild cognitive impairment (MCI) were randomly assigned to either an experimental (n=11) or a control group (n=11). The experimental group received 15 cognitive training sessions through tasks involving the auditory domain. The outcome measures of this study included auditory resolution (Temporal gap detection, frequency discrimination, and modulation detection) and cognitive measures (Trail making tests and digit recall), which were administered at three-time points (before training, post-training, and follow-up). The linear mixed model computed the effects of training on the outcome measures. Results A significant improvement was observed in the modulation detection threshold between baseline and follow-up and between post-training and follow-up sessions. However, GDT and FD thresholds did not reveal any statistically significant difference. In the trail making test, Part B showed consistent significance across the time points, whereas Part A and the delayed recall task showed no significant difference. Conclusion Auditory-based cognitive training may improve auditory processing and executive function in older adults with mild cognitive impairment (MCI).

Effects of Information and Communication Technology Use on the Executive Function of Older Adults Without Dementia: A Longitudinal Fixed-effect Analysis.

Impaired executive function is common in older adults. This study examined the causal relationship between the use of information and communication technology (ICT) and executive function in older adults over time. This study performed a secondary analysis of data from four waves (2016-2019) of the National Health and Aging Trends Study (NHATS). A fixed-effect analysis was conducted to examine the effects of ICT on the executive function of older adults without dementia aged ≥65 years. This study analyzed data from 3,334 respondents. We observed significant positive effects of ICT use on executive function over time (standardized β = 0.043-0.045, 95% confidence interval [CI] = 0.001-0.043, p < 0.05). The current findings support the use of ICT as a protective approach to prevent decline in executive function in community-dwelling older adults.

Tai Chi Practice Buffers Aging Effects in Functional Brain Connectivity.

Tai Chi (TC) practice has been shown to improve both cognitive and physical function in older adults. However, the neural mechanisms underlying the benefits of TC remain unclear. Our primary aims are to explore whether distinct age-related and TC-practice-related relationships can be identified with respect to either temporal or spatial (within/between-network connectivity) differences. This cross-sectional study examined recurrent neural network dynamics, employing an adaptive, data-driven thresholding approach to source-localized resting-state EEG data in order to identify meaningful connections across time-varying graphs, using both temporal and spatial features derived from a hidden Markov model (HMM). Mann-Whitney U tests assessed between-group differences in temporal and spatial features by age and TC practice using either healthy younger adult controls (YACs, n = 15), healthy older adult controls (OACs, n = 15), or Tai Chi older adult practitioners (TCOAs, n = 15). Our results showed that aging is associated with decreased within-network and between-network functional connectivity (FC) across most brain networks. Conversely, TC practice appears to mitigate these age-related declines, showing increased FC within and between networks in older adults who practice TC compared to non-practicing older adults. These findings suggest that TC practice may abate age-related declines in neural network efficiency and stability, highlighting its potential as a non-pharmacological intervention for promoting healthy brain aging. This study furthers the triple-network model, showing that a balancing and reorientation of attention might be engaged not only through higher-order and top-down mechanisms (i.e., FPN/DAN) but also via the coupling of bottom-up, sensory-motor (i.e., SMN/VIN) networks.
