RESUMO

Background Chronic conditions may limit older peoples' social engagement and wellbeing. Reduced social connections can result in loneliness and social isolation. This study aimed to explore the experience of social connection in older people living with chronic conditions, and the factors influencing their social participation. Methods A purposive sample of 19 community-dwelling older Australians (mean age 75.5years) with one or more chronic conditions participated in a qualitative descriptive study. Semi-structured interviews explored participants' perceptions of their social connections and the potential impact of their chronic conditions. Views about the role of general practice in supporting older persons' wellbeing were discussed. Data were analysed inductively using thematic analysis. Results Five themes were identified: (1) the experience of loneliness, (2) managing diminishing social contacts, (3) living with chronic conditions, (4) barriers to social connection, and (5) facilitators of social connection. Participants felt that ageing with chronic conditions contributed to loss of function and independence, which limited social connections, and increased loneliness and social isolation. Barriers to social connections included issues with mobility, transport and forming new networks. Families were a primary support, with continued community engagement and general practice support crucial to staying well and socially connected. Conclusions Understanding older peoples' experiences, and the barriers and facilitators of social connections can guide clinicians' interventions. General practice is a promising intervention point because of its high use by those with chronic conditions to stay well. General practice nurses are well-placed to collaboratively address the barriers older people face in maintaining social connections.

RESUMO

BACKGROUND: Social media may be a useful method for research centers to deliver health messages, increase their visibility in the local community, and recruit study participants. Sharing examples of social media-based community outreach and educational programs, and evaluating their outcomes in this setting, is important for understanding whether these efforts have a measurable impact. OBJECTIVE: The aim of this study is to describe one center's social media activities for community education on topics related to aging, memory loss, and Alzheimer disease and related dementias, and provide metrics related to recruitment into clinical research studies. METHODS: Several social media platforms were used, including Facebook, X (formerly Twitter), and YouTube. Objective assessments quantified monthly, based on each platform's native dashboard, included the number of followers, number of posts, post reach and engagement, post impressions, and video views. The number of participants volunteering for research during this period was additionally tracked using a secure database. Educational material posted to social media most frequently included content developed by center staff, content from partner organizations, and news articles or resources featuring center researchers. Multiple educational programs were developed, including social media series, web-based talks, Twitter chats, and webinars. In more recent years, Facebook content was occasionally boosted to increase visibility in the local geographical region. RESULTS: Up to 4 years of page metrics demonstrated continuing growth in reaching social media audiences, as indicated by increases over time in the numbers of likes or followers on Facebook and X/Twitter and views of YouTube videos (growth trajectories). While Facebook reach and X/Twitter impression rates were reasonable, Facebook engagement rates were more modest. Months that included boosted Facebook posts resulted in a greater change in page followers and page likes, and higher reach and engagement rates (all P≤.002). Recruitment of participants into center-affiliated research studies increased during this time frame, particularly in response to boosted Facebook posts. CONCLUSIONS: These data demonstrate that social media activities can provide meaningful community educational opportunities focused on Alzheimer disease and related dementias and have a measurable impact on the recruitment of participants into research studies. Additionally, this study highlights the importance of tracking outreach program outcomes for evaluating return on investment.

RESUMO

PURPOSE: This study aimed to develop a normal brain ageing model based on magnetic resonance imaging and radiomics, therefore identifying radscore, an imaging indicator representing white matter heterogeneity and exploring the significance of radscore in detecting people's cognitive changes. METHODS: Three hundred sixty cognitively normal (CN) subjects from the Alzheimer's Disease Neuroimaging Initiative (ADNI) database and 105 CN subjects from the Parkinson's Progression Markers Initiative database were used to develop the model. In ADNI, 230 mild cognitive impairment (MCI) subjects were matched with 230 CN old-aged subjects to evaluate their heterogeneity difference. One hundred four MCI subjects with 48 months of follow-up were divided into low and high heterogeneity groups. Kaplan-Meier survival curve analysis was used to observe the importance of heterogeneity results for predicting MCI progression. RESULTS: The area under the receiver operating characteristic curve of the model in the training, internal test and external test sets was 0.7503, 0.7512 and 0.7514, respectively. There was a significantly positive correlation between age and radscore of CN subjects (r = 0.501; P < .001). The radscore of MCI subjects was significantly higher than that of matched CN subjects (P < .001). The median radscore ratios of MCI to CN from four age groups (66-70y, 71-75y, 76-80y and 81-85y) were 1.611, 1.760, 1.340 and 1.266, respectively. The probability to progression of low and high heterogeneity groups had a significant difference (P = .002). CONCLUSION: When radscore is significantly higher than that of normal ageing, it is necessary to alert the possibility of cognitive impairment and deterioration.

RESUMO

BACKGROUND: Prior research has identified the mediating effect of physical activity in the relationship between self-perceptions of aging and physical health. However, this impact on mental health is unknown, and the influence of environmental contexts proposed by ecological models in this regard remains largely unexplored. Therefore, this study aimed to investigate the role of physical activity in the relationship between self-perceptions of aging and depressive symptoms in older adults, and compare the impact across four levels of neighborhood walkability. METHODS: A sample of 1,055 community-dwelling older adults aged 65 or above was obtained through random-digit-dialing computer-assisted telephone interviewing. The individual's neighborhood walkability was calculated using Walk Score®, and categorized into four levels: car-dependent, somewhat walkable, very walkable, and walker's paradise. Partial least squares structural equation modelling was employed. RESULTS: We found that more positive self-perceptions of aging were associated with fewer depressive symptoms and a mediation effect of physical activity in this relationship. Among the four levels of neighborhood walkability, the mediation effect of physical activity was only statistically significant in the lowest level (car-dependent). The findings supported our hypotheses regarding the mediating effect of self-perceptions of aging on depressive symptoms via physical activity. Neighborhood walkability might potentially influence the mediating role of physical activity. CONCLUSIONS: This study emphasizes key areas on intervention programs and policy formulation to promote mental health in older adults.

RESUMO

OBJECTIVES: Evidence suggests spouses influence each other's subjective views on aging. Aligned with the Theory of Dyadic Illness Management, we investigated for the first time similarities in felt age (how old people feel relative to their chronological age) between people with dementia and their spousal caregivers, and how each partner's felt age was related to psychological correlates in the other partner. METHODS: We used baseline (2014-2016) data from 1,001 people with dementia and their spousal caregivers who participated in the British Improving the experience of Dementia and Enhancing Active Life study. We ran linear regressions to analyze the extent to which the felt age of people with dementia and their caregivers were similar, and whether relationship quality was associated with the similarity. We utilized actor-partner interdependence models to analyze whether the felt age of people with dementia and their caregivers were associated with each other's well-being, satisfaction with life, and self-efficacy. RESULTS: The felt age of people with dementia was associated with the felt age of their caregivers (ß = 0.10; p = .001). Caregivers and people with dementia reported a more similar felt age when caregivers rated the caregiving relationship more positively (ß = 0.07; p = .04). Caregivers' felt age was associated with well-being (ß = 0.07; p = .02) and satisfaction with life (ß = 0.06; p = .04), but not with self-efficacy, in people with dementia. DISCUSSION: Felt age in caregivers and people with dementia may be interwoven, and important psychological variables in people with dementia are related to caregivers' felt age. Findings offer empirical evidence on dementia caregiving dynamics and how family relationships are related to views on aging.

RESUMO

BACKGROUND: Functional capacity is recognized as a central factor for health in old age and not all studies that seek to clarify the role of social relationships in functional capacity are conclusive. The subject has only been studied in a limited way in Latin America, a region that is aging prematurely, with evidence primarily from developed countries, which have experienced a more gradual aging of their population. This longitudinal study aimed to determine how aspects of social relationships impact the functionality of older Chileans. METHODOLOGY: We conducted a cohort study of 2,265 people aged 60 years or older who lived in the community and resided in Greater Santiago, Chile. Five aspects of social relationships were considered at baseline (participation in groups, clubs, or organizations; number of people in the household; participation in recreational activities; perception of material support, help or advice, and marital status), from which a cluster analysis by conglomerate was performed and used as the exposure of interest. Functional limitation (FL) was the dependent variable, classified as a limitation in at least 1 basic activity of daily living or 1 instrumental activity or 2 advanced activities. The control variables considered were: sex, age, educational level, multimorbidity, depression and years of follow-up. Survival analyses using a Cox proportional hazard regression and multilevel logistic regressions (person level and follow-up wave level) were performed. RESULTS: The identified clusters were four: "without social participation and does not live alone"; "without a partner and without social participation"; "no perception of support and no social participation"; "with participation, partner and perception of support". Social relationship clusters predicted FL incidence and FL reporting during follow-up. Being in the clusters "without social participation and does not live alone" and "without partner and without social participation" were risk factors for incident FL and report of FL during follow-up, compared to being in the reference cluster "with participation, partner and perception of support. CONCLUSIONS: In summary, our study showed that participating in social organizations, not living alone and having a partner are protective factors for presenting and developing functional limitation in old age for community-living Chileans in an urban area.

RESUMO

Decline in spatial context memory emerges in midlife, the time when most females transition from pre- to post-menopause. Recent evidence suggests that, among post-menopausal females, advanced age is associated with functional brain alterations and lower spatial context memory. However, it is unknown whether similar effects are evident for white matter (WM) and, moreover, whether such effects contribute to sex differences at midlife. To address this, we conducted a study on 96 cognitively unimpaired middle-aged adults (30 males, 32 pre-menopausal females, 34 post-menopausal females). Spatial context memory was assessed using a face-location memory paradigm, while WM microstructure was assessed using diffusion tensor imaging. Behaviorally, advanced age was associated with lower spatial context memory in post-menopausal females but not pre-menopausal females or males. Additionally, advanced age was associated with microstructural variability in predominantly frontal WM (e.g., anterior corona radiata, genu of corpus callosum), which was related to lower spatial context memory among post-menopausal females. Our findings suggest that post-menopausal status enhances vulnerability to age effects on the brain's WM and episodic memory.

RESUMO

Age-related episodic memory decline is attributed to functional alternations in the hippocampus. Less clear is how aging affects the functional connections of the hippocampus to the rest of the brain during episodic memory processing. We examined fMRI data from the CamCAN dataset, in which a large cohort of participants watched a movie (N = 643; 18-88 years), a proxy for naturalistic episodic memory encoding. We examined connectivity profiles across the lifespan both within the hippocampus (anterior, posterior), and between the hippocampal subregions and cortical networks. Aging was associated with reductions in contralateral (left, right) but not ipsilateral (anterior, posterior) hippocampal subregion connectivity. Aging was primarily associated with increased coupling between the anterior hippocampus and regions affiliated with Control, Dorsal Attention and Default Mode networks, yet decreased coupling between the posterior hippocampus and a selection of these regions. Differences in age-related hippocampal-cortical, but not within-hippocampus circuitry selectively predicted worse memory performance. Our findings comprehensively characterize hippocampal functional topography in relation to cognition in older age, suggesting that shifts in cortico-hippocampal connectivity may be sensitive markers of age-related episodic memory decline.

RESUMO

BACKGROUND: Depression in ageing adults is a public health problem. Worldwide studies have identified social and health risk factors for depressive symptoms. However, little is known about their longitudinal determinants in Mexico. OBJECTIVES AND SETTING: To find the prevalence of depressive symptoms and their longitudinal individual and contextual risk factors in Mexican adults aged 50 and older. DESIGN: Secondary data of 6460 persons aged 50 years and older from the Mexican Health and Aging Study were analysed using a 'between-within' panel data analysis approach. RESULTS: The prevalence of depressive symptoms increased from 35% in 2003 to 38% in 2015. The significantly longitudinal factors associated with these symptoms were getting older (OR 1.02, 95% CI 1.01 to 1.03), being a woman (OR 2.39, 95% CI 2.16 to 2.64), less time spent in formal education (0 years and less than 6 years OR 1.52, 95% CI 1.32 to 1.75 and OR 1.33, 95% CI 1.19 to 1.50, respectively), lower net worth (OR 1.13, 95% CI 1.08 to 1.17), being recently unemployed (OR 1.25, 95% CI 1.10 to 1.25), increased (OR 1.17, 95% CI 1.10 to 1.25) or increasing number (OR 1.23, 95% CI 1.15 to 1.31) of chronic conditions, poor (OR 4.68, 95% CI 4.26 to 5.15) or worsened (OR 1.71, 95% CI 1.61 to 1.81) self-rated health and having impairments on instrumental activities of daily living (IADLs) (OR 2.94 95% CI 2.35 to 3.67) or a new IADL impairment (OR 1.67, 95% CI 1.48 to 1.89), as well as having impairments on ADLs (OR 1.51, 95% CI 1.23 to 1.86) or a new ADL impairment (OR 1.34, 95% CI 1.21 to 1.48). CONCLUSIONS: The prevalence of depressive symptoms in Mexican adults aged 50 and older is high. Our findings show that they are longitudinally associated with the individual's demographic, socioeconomic, health and disability characteristics. Efforts in public policy should focus on preventing chronic conditions and disability, as well as fighting inequalities to reduce the prevalence of depressive symptoms.

RESUMO

BACKGROUND: The purpose of this study was to investigate the relationship between blood-brain barrier (BBB) permeability and cognitive functioning in healthy older adults and individuals with neurodegenerative diseases. METHODS AND RESULTS: A total of 124 participants with Alzheimer disease, cerebrovascular disease, or a mix Alzheimer's and cerebrovascular diseases and 55 controlparticipants underwent magnetic resonance imaging and neuropsychological testing. BBB permeability was measured with dynamic contrast-enhanced magnetic resonance imaging and white matter injury was measured using a quantitative diffusion-tensor imaging marker of white matter injury. Structural equation modeling was used to examine the relationships between BBB permeability, vascular risk burden, white matter injury, and cognitive functioning. Vascular risk burden predicted BBB permeability (r=0.24, P<0.05) and white matter injury (r=0.38, P<0.001). BBB permeability predicted increased white matter injury (r=0.34, P<0.001) and increased white matter injury predicted lower cognitive functioning (r=-0.51, P<0.001). CONCLUSIONS: The study provides empirical support for a vascular contribution to white matter injury and cognitive impairment, directly or indirectly via BBB permeability. This highlights the importance of targeting modifiable vascular risk factors to help mitigate future cognitive decline.

RESUMO

Few studies have examined the relationship between life satisfaction, emotional regulation and perception of future time in the elderly. Thirty-one women and 28 men (age M = 70,51 ± 3,98) were questioned using the Gross and John's Emotion Regulation Questionnaire (2003), the Blais et al.'s Life Satisfaction Scale (1989) and the Castersen and Lang's Future Time Perception Scale (1996). The results show that there is no gender effect, and do not support the motivational theory of Carstensen, Isaacowitch and Charles (1999), which postulates a link between temporal perspective and the selection of the most efficient emotional regulation strategies. This research shows that it is the use of compensatory strategies that enables people to continue to be satisfied with their lives despite advancing age. Nor do these strategies influence the effect of gender or perception of future time on life satisfaction. Against a backdrop of an aging population, this study is helping to better define the features of well-being in the advancing age.

RESUMO

Prospective memory allows us to remember to perform an action in the future in response to environmental cues (event-based) or predetermined times (time-based). It is often impaired in individuals with mild cognitive impairment. These deficits are related to various cognitive functions such as episodic memory and executive functions and are particularly affected in pathological ageing. In this article, we propose a literature review of non-pharmacological interventions with the elderly with MCI and neurodegenerative diseases. This article explores different strategies for managing prospective memory, including cognitive training, mnemonic strategies, and external aids. In all cases, it is important to design personalized interventions that take account of patients' individual characteristics. Research into the long-term effectiveness of these strategies is still limited, and further studies are needed to properly assess their benefits.

RESUMO

Increased variability in cognitive scores, mood or personality traits can be indicative of underlying neurological disorders. Whether variability in cognition is due to changes in mood or personality is unknown. A total of 66 younger adults, 51 healthy older adults and 38 participants with cognitive impairment completed 21 daily sessions of attention, working memory, mood, and personality assessment. Group differences in mean performance and variability were examined using Bayesian mixed effects location scale models. Variability in attention decreased from younger to older adults and then increased again in cognitive impairment. Younger adults were more variable in agreeableness, openness and conscientiousness compared to older adults. The clinically impaired group differed from the healthy older adults in terms of variability on attention, openness, and conscientiousness. Healthy aging results in greater stability in personality traits over short intervals yet this stability is not redundant with increased stability in cognitive scores.

RESUMO

Cognitive Reserve (CR) reflects acquired knowledge, skills, and abilities throughout life, and it is known for modulating cognitive efficiency in healthy and clinical populations. CR, which was initially proposed to explain individual differences in the clinical presentation of dementia, has subsequently been extended to healthy ageing, showing its role in cognitive efficiency also during middle age. Recently, CR has been linked to affective processes in psychiatric conditions such as schizophrenia, major depressive and anxiety symptoms, and psychological distress, suggesting its potential role in emotional expression and regulation. Whether the role of CR in mental health extends to non-pathological adults, and whether this is only relevant in older age is not yet clear. The aim of this work was therefore to explore the relationship between CR and mental health in healthy adults, with a focus on middle adulthood (40-60). In a sample of 96 participants, we found a positive association between CR and mental health outcomes, such that a higher cognitive reserve index corresponded to fewer mental health reported symptoms. Specifically, a higher CR reflecting professional activities was associated with lower stress levels, especially in middle agers. Taken together, these data therefore suggest that engaging occupations may help maintain a robust mental health, especially by reducing stress symptoms during middle age. These results broaden previous findings suggesting that CR relates to affective components of mental health in middle aged and older adults.

RESUMO

Age-related changes in emotional processing are complex, with a bias toward positive information. However, the impact of aging on emotional responses in positive everyday situations remains unclear. Virtual Reality (VR) has emerged as a promising tool for investigating emotional processing, offering a unique balance between ecological validity and experimental control. Yet, limited evidence exists regarding its efficacy to elicit positive emotions in older adults. Our study aimed to explore age-related differences in positive emotional responses to immersion in both social and nonsocial virtual emotional environments. We exposed 34 younger adults and 24 older adults to natural and social 360-degree video content through a low immersive computer screen and a highly immersive Head-Mounted Display, while recording participants' physiological reactions. Participants also provided self-report of their emotions and sense of presence. The findings support VR's efficacy in eliciting positive emotions in both younger and older adults, with age-related differences in emotional responses influenced by the specific video content rather than immersion level. These findings underscore the potential of VR as a valuable tool for examining age-related differences in emotional responses and developing VR applications to enhance emotional wellbeing across diverse user populations.

RESUMO

INTRODUCTION: Delirium and multiple long-term conditions (MLTC) share numerous risk factors and have been shown individually to be associated with adverse outcomes following hospitalisation. However, the extent to which these common ageing syndromes have been studied together is unknown. This scoping review aims to summarise our knowledge to date on the interrelationship between MLTC and delirium. METHODS: Searches including terms for delirium and MLTC in adult human participants were performed in PubMed, EMBASE, Medline, Psycinfo and CINAHL. Descriptive analysis was used to summarise findings, structured according to Synthesis Without Meta-analysis reporting guidelines. RESULTS: After removing duplicates, 5256 abstracts were screened for eligibility, with 313 full-texts sought along with 17 additional full-texts from references in review articles. In total, 140 met inclusion criteria and were included in the final review. Much of the literature explored MLTC as a risk factor for delirium (n = 125). Fewer studies explored the impact of MLTC on delirium presentation (n = 5), duration (n = 3) or outcomes (n = 6) and no studies explored how MLTC impacts the treatment of delirium or whether having delirium increases risk of developing MLTC. The most frequently used measures of MLTC and delirium were the Charlson Comorbidity Index (n = 98/140) and Confusion Assessment Method (n = 81/140), respectively. CONCLUSION: Existing literature largely evaluates MLTC as a risk factor for delirium. Major knowledge gaps identified include the impact of MLTC on delirium treatment and the effect of delirium on MLTC trajectories. Current research in this field is limited by significant heterogeneity in defining both MLTC and delirium.

Few studies have focused sufficiently on the intricate link between functional health and depression among older people aged 60 and above in India. Therefore, the current study investigates the association between functional health and depression among older Indian adults through the mediating role of social disengagement and loneliness and the moderating role of living arrangements using recent data from the Longitudinal Aging Study in India (LASI: 2017-2018). Composite International Diagnostic Interview-Short Form (CIDI-SF) for depression, the Activities of Daily Living (ADL) and Instrumental Activities of Daily Living (IADL) for functional health, and the indoor/outdoor activities, visits, and religious events for social disengagement were used. The feelings of loneliness and living arrangements were measured using single-item questions and surveys/interviews of household members. Bivariate analysis, logistic regression, and a Partial Least Squares-Structural Equation Model were adopted. The results show that older persons with functional health had 1.85 times higher odds of depression; similarly, those not engaging in social activities and experiencing loneliness were more likely to feel depressed. Living with someone was negatively linked to depression. A significant moderation by living arrangements in the functional health-depression relationship was also observed. The results also indicate significant mediating roles of social disengagement and loneliness, with 22.0% and 3.08% mediation effects, respectively. Therefore, this study recommends the provision of housing and social interaction among older people.

RESUMO

Aging is an inevitable and complex biological process that is associated with a gradual decline in physiological functions and a higher disease susceptibility. Omega-3 fatty acids, particularly docosahexaenoic acid, play a crucial role in maintaining brain health and their deficiency is linked to age-related cognitive decline. Combining omega-3-rich diets with exercise may enhance cognitive function more effectively, as both share overlapping neurobiological and physiological effects. This study aimed to evaluate the effect of exercise and omega-3 fatty acid (FA) supplementation in two different doses (160 mg/kg and 320 mg/kg) on anxiety-like behavior and cognitive abilities in both adult and aged rats. Male Wistar rats (4-5- and 23-24-month-old) were randomly divided into seven groups: 3-week control supplemented with placebo without exercise, low-dose omega-3 FAs, high-dose omega-3 FAs, 7-week control supplemented with placebo without exercise, exercise-only, low-dose omega-3 FAs with exercise, and high-dose omega-3 FAs with exercise. The administered oil contained omega-3 FAs with DHA:EPA in a ratio of 1.5:1. Our results indicate that aging negatively impacts the locomotor and exploratory activity of rats. In adult rats, a low dose of omega-3 FAs reduces locomotor activity when combined with exercise while high dose of omega-3 FAs reduces anxiety-like behavior and improves recognition memory when combined with exercise. The combination of omega-3 FAs and exercise had varying impacts on behavior, suggesting a need for further research in this area to fully understand their therapeutic efficacy in the context of cognitive changes associated with aging.

RESUMO

BACKGROUND: Most people want to remain at home as they age. Ageing in place - remaining at home and connected to the community - is a national and international policy priority; however, to better understand how policy might be implemented, a more nuanced understanding is required about older adults' lived experiences of ageing in place, especially the experiences of those aged 80 and above. OBJECTIVE: To describe and explore the social processes which enable ageing in place from the perspective of community-dwelling older people (80+). METHODS: Forty-six respondents (80-100+ years) participated in the first wave of a longitudinal qualitative study set in North East England. Semi-structured interviews were conducted in participants' homes between June 2022 and January 2023. Interviews were analysed using reflexive thematic analysis. RESULTS: Participants positioned their homes as a place of freedom and as the antithesis of a 'care home'. Remaining in place was important for all participants; a key priority for them was to remain physically active to enable this. However, many participants faced significant hurdles to remaining in place. These were primarily related to health and mobility issues. Some participants were able to overcome such barriers by drawing on financial resources and available social networks. CONCLUSION: The home is central to understanding older peoples' (80+) experiences of ageing. In a socio-political context which promotes ageing in place, the social factors shaping experiences of ageing in place must be considered. This involves attending to the challenges of later life, particularly health and especially mobility and physical function. Currently, those with resources (social and economic) are better equipped to respond to such challenges, thus potentially exacerbating widening inequalities in ageing. By foregrounding the perspectives of those ageing in place alongside social factors shaping their experiences, our study has important implications for policy and health and social care. We show that a more equitable allocation of resources is vital to fulfil the ageing in place policy agenda. Furthermore, we highlight a need to recognise commitments to ageing in place displayed by people aged 80 and above, especially when remaining in place becomes difficult to achieve.
