Significant gaps remain in our knowledge of cognitive aging in Hispanic adults, the largest and fastest-growing minority group in the United States (U.S.). Episodic autobiographical memory (EAM), which has well documented age-related differences, has not been directly examined in older U.S. Hispanic adults – a population that is commonly bilingual. This study aimed to examine the effects of Spanish-English bilingualism and aging on EAM among Hispanic adults.
Methods:
In the present study 100 young and middle-aged/older Hispanic adults (50 English–Spanish bilingual Hispanic participants and 50 monolingual English-speaking Hispanic participants) narrated EAMs in a structured interview. We assessed these narratives for episodic and non-episodic details using an established scoring protocol.
Results:
We replicated the commonly observed age-related decrease in episodic detail generation among Hispanic participants, with non-episodic detail not significantly differing between young and older Hispanic participants. Among young Hispanic participants, bilingualism was associated with higher episodic, but not non-episodic, detail generation. This bilingualism advantage for episodic detail, however, was not evident among older Hispanic participants.
Conclusions:
These results underscore the complex interplay between bilingualism and age in autobiographical memory for events among Hispanic adults. Our study highlights the importance of including diverse racial/ethnic and linguistic samples in cognitive aging research to better understand how bilingualism and cultural factors influence memory across the lifespan.
Few studies examine the relationship between physical activity, multiple physical fitness domains (cardiorespiratory fitness, strength, speed), and cognition. Our objective was to investigate the association between physical activity and executive function in middle-aged and older adults and examine whether modifiable physical fitness components explain the relationship between physical activity and cognition.
Method:
Self-reported moderate-to-vigorous physical activity and objective measures of cardiorespiratory fitness (2-minute walk test), strength (grip strength), speed (4-meter walk test), and executive function were collected from 623 adults within the Human Connectome Project–Aging (ages 36 – 100 years; mean = 59.2 years; 57.8% female). Relative importance metrics, multiple regression, and conditional process analysis were used to examine relationships of age, physical activity, and physical fitness with executive function.
Results:
Greater physical fitness was related to better executive function performance (β = 0.28, p < .001). Physical activity was not associated with executive function (β = −0.04, p = .16). There was an indirect relationship between physical activity and executive function through physical fitness (ab = 0.02, 95% CI: 0.004 – 0.04). This association was explained primarily by the indirect association of cardiorespiratory fitness with physical activity and executive function. The indirect association of cardiorespiratory fitness with physical activity and executive function was significant in older study participants (mean (59 years) and + 1 SD (74 years)), but not younger (−1 SD (44 years)), although between-group comparisons were not significant.
Conclusions:
These data highlight potential differential associations with cognition when considering physical activity and physical fitness, and the importance of considering multiple domains of physical fitness in relation to physical activity and cognitive performance.
Ensuring seed viability over decades is a central challenge in ex situ conservation of plant genetic resources. Standard germination tests, while effective, are destructive and fail to detect early molecular damage that precedes viability loss. RNA integrity has emerged as a promising biomarker due to the inherent vulnerability of mRNA to oxidative degradation in the dry state. In this study, we identified and validated seed-stored mRNAs in common bean (Phaseolus vulgaris), a major crop species extensively represented in global germplasm collections, and investigated transcript degradation patterns in seeds conserved for up to 30 years. Using a comparative genomics approach, we identified 107 P. vulgaris orthologs of long-lived rice mRNAs, many encoding proteins involved in RNA stabilization, oxidoreductase activity, and primary metabolism. Thirty transcripts were validated by RT-qPCR, and the integrity of nine was assessed using paired primers targeting 5′ and 3′ regions. Degradation followed a consistent 5′→3′ pattern, particularly in longer transcripts, and correlated strongly with germination power. Predictive performance varied across transcripts: PSMA4, SMP1, and TRA2 consistently showed strong correlations with viability, whereas others were less informative. The ΔΔCq metric improved resolution by detecting degradation asymmetry. Samples included a genetically diverse panel of conserved, regenerated, and artificially aged accessions, enhancing applicability to real-world genebank conditions. Artificial aging intensified degradation signatures and mirrored patterns observed in naturally aged seeds. Altogether, our results indicate transcript integrity as a molecular biomarker for seed viability, supporting the development of robust molecular tools to inform decision-making and regeneration planning in long-term germplasm conservation.
Engaging residents of long-term care homes (LTCHs) in their home’s environment, programs, and operations is required in some jurisdictions and could improve resident quality of life and other outcomes. This scoping review summarized existing research on resident engagement in LTCH organizational design and governance, including associated enablers, barriers, approaches, and outcomes. The database search yielded 5,580 records (after deduplication), and 62 articles covering 59 studies were included. These studies predominantly described Residents’ Councils (n = 38; 64%) and enablers or barriers pertaining to resident and home perspectives, as well as implementation and sustainability infrastructure. Few studies described approaches to considerations of resident diversity (n = 8; 14%) or the presence of dementia and/or cognitive impairment (n = 12; 20%). Ten studies reported quantitative data evaluating resident engagement, and only four with resident-reported outcomes. Robust, evidence-informed frameworks that are co-designed with residents, staff, and others in the LTCH sector are needed to engage residents in their LTCHs.
In this chapter, we review empirical and conceptual work pertaining to organic changes in the brain and shifting goals as contributors to age-related changes in affective processing. We argue for the need to integrate these two previously isolated lines of research by delineating their crucial interplay toward a comprehensive understanding of affective neuroscience in aging. We present examples of aging trajectories, impacted by organic brain and motivational change, to identify key processes of interest for future research and potent intervention targets to promote successful aging. We conclude with open basic and applied research questions embedded within our integrated conceptual framework to guide future research on affective neuroscience in aging.
Schizophrenia spectrum disorders confer an increased and earlier dementia diagnosis risk, but the relative timing and course of cognitive decline compared to individuals with affective disorders is unclear.
Methods
This retrospective study used de-identified electronic patient records to compare cognitive trajectories from the first recorded MMSE, representing the earliest cognitive concerns in relation to a possible dementia syndrome, and subsequent dementia risk between patients with a schizophrenia spectrum and primary affective disorder diagnosis. Patients had at least two MMSE scores recorded at least 6 months apart. We examined annual MMSE change from the first recorded MMSE, dementia risk, dementia subtypes, and rates of dementia assessment and treatment.
Results
Compared to affective disorders (n = 2,264; 71.1 years), schizophrenia spectrum disorders (n = 1,217; 65.0 years) showed earlier initial MMSE scores (by 6.1 years, 95% CI = 5.2–7.0), earlier dementia diagnoses (by 2.3 years, 95% CI = 0.9–3.7) but lower dementia risk (adjusted HR = 0.81; 95% CI = 0.69–0.95). Cognitive decline rates and dementia subtype diagnoses did not differ between affective and schizophrenia spectrum disorders, but it took longer for schizophrenia spectrum disorder patients to receive a dementia diagnosis (5.6 vs. 4.4 years). Anti-dementia medication was less likely to be prescribed in patients with schizophrenia versus depression.
Conclusions
Cognitive concerns in older individuals with schizophrenia spectrum disorders arise from around 63 years and are associated with earlier dementia risk versus older individuals with affective disorders. Findings emphasize the importance of targeted dementia prevention and treatment strategies in these individuals and the need to reduce the existing inequity of access to dementia services.
Approximately 25% of older adult residents who experience an acute change in health status are transferred from Long-Term Care (LTC) to Emergency Departments (ED). We explored the use of an intervention (i.e., LTC to ED) care and referral pathway, INTERACT® Change in Condition cards, and STOP AND WATCH tool, in informing decision making regarding resident transfers. We conducted 22 semi-structured interviews with Health care Providers (HCPs) involved in the LTC to ED care pathway in Western Canada. Thematic analysis of the qualitative interviews was used to evaluate the use of the pathway and tools. We identified six themes influencing decision making around resident transfers including interprofessional practice and conflict, ambiguous and clear medical cases, ageism, health care providers’ goals, family involvement in resident care, and intervention tools. The intervention may be useful in streamlining, documenting, and increasing transparency in complicated LTC resident care and transfer decisions.
This chapter delves into the multifaceted dimensions of aging and senescence, given the rapidly aging global population. While aging research traditionally centered on frailty and illness, contemporary discourse emphasizes the concept of “aging well” and preserving one’s youthful vigor. Anthropological studies adopt a comparative lens, recognizing the contextual variations in what constitutes “successful aging.” This chapter underscores the role of local cultural understandings in shaping individual experiences of aging and decline. Care emerges as a central theme, intricately woven within political, economic, and social power dynamics. Sakti’s research, with a focus on contexts of involuntary migration and mobility, sheds light on the challenges faced by older individuals navigating displacement and loss in a post-conflict setting. The Timor-Leste case reveals how older individuals reconstruct their lives amidst upheaval, intertwining notions of care, interdependence, and ancestral connections. This exploration challenges conventional notions of aging well, emphasizing the interconnectedness of individual and collective well-being within broader social and cultural contexts.
La gestion socioterritoriale du vieillissement constitue un enjeu fondamental au Nouveau-Brunswick. Comme cette province ne possède pas de stratégie territoriale du vieillissement, il revient aux municipalités d’aménager leur territoire afin de favoriser le vieillissement sur place. L’objectif de cet article consiste à évaluer la perception des élus municipaux, des intervenants communautaires et des aînés en ce qui a trait à la gestion socioterritoriale du vieillissement dans quatre villes du Nouveau-Brunswick. L’approche utilisée est celle des représentations sociales des acteurs à partir d’entrevues semi-dirigées. Sur le plan théorique, notre analyse s’appuie sur le modèle de gérontologie environnementale. Bien que les résultats de nos entretiens révèlent une satisfaction généralisée des répondants concernant l’implication des élus à la gestion socioterritoriale du vieillissement, des disparités persistent notamment au chapitre de l’accessibilité par rapport à certains édifices et au manque d’infrastructures dédiées spécifiquement aux aînés. Pour pallier ces difficultés, le déploiement d’une stratégie territoriale du vieillissement multiniveau constitue une piste de solutions à envisager.
The COVID-19 pandemic highlighted significant vulnerabilities in long-term care (LTC) homes, severely impacting residents and care partners. This study investigates how care partners of older adults living in Ontario LTC homes perceived residents’ experiences during the COVID-19 pandemic, and how those perceptions shaped their own caregiving experiences. Using critical ethnography, we identified four key themes: (a) masks and miscommunication, (b) loneliness and loss, (c) from interaction to isolation, and (d) loss of the advocacy role. Supportive actions included transparent masks, increased allied health professionals, and enriching daily programs. These findings emphasize the need for policies that balance infection control with the emotional and social needs of LTC residents, addressing power imbalances, ageism, and systemic inequities.
Although residents of The Villages often say, "You name it, they have a club for it, and if they don’t, you can start one," moving to the city frequently necessitates quitting or reducing involvement in existing activities. Additionally, aging presents various challenges to participation, such as declining health and lack of companionship. Based on the ecological model of leisure constraints, this chapter explores how residents navigate these conditions, why some choose not to negotiate them, and how the vast array of activities in The Villages both supports and hinders successful negotiation.
The opening chapter sets the stage for the book. It starts with a recount of the author’s first day at The Villages and her motivation to explore the aging experience in this "city for seniors." The second part details the study that forms the book’s foundation, including the research questions, methods, and participant descriptions. The third part outlines the book’s structure, providing a brief overview of each chapter.
After outlining the history of The Villages from its origins as a trailer park in the late 1960s to its present status, this chapter examines the factors behind its success. This discussion covers the unique master planning of the community, the extensive variety of leisure activities available to residents, and the population’s relative homogeneity. By distinguishing between the place and its residents, the chapter also reviews previous research on The Villages and identifies the gaps in the existing knowledge that this book aims to fill.
The final chapter compares The Villages to other retirement communities, aging in place, and aging in community. Drawing on the study’s findings and the perceptions of interviewed individuals, it highlights how The Villages’ unique characteristics – including its size, innovation culture, bubble communication, opportunities for meaningful involvement, social networks, and communal coping – generally enhance residents’ well-being. The chapter also summarizes The Villages’ weaknesses and presents key takeaways about the societal meanings of its success.
With 115 recreation centers, 3,000 clubs, numerous activities, and media content that encourages residents to “Try something new!” The Villages actively promotes innovation in later life. Drawing on innovation theory, this chapter examines the continuity and change in residents’ leisure activities upon moving to The Villages and over time. It describes what can be termed an "innovation culture" while also noting that innovation tends to decline with age and pointing to a greater tendency towards self-preservation rather than self-reinvention innovation.
For The Villagers, "fun" is a serious matter. This chapter highlights the remarkable volunteering patterns among residents and analyzes them through the lens of the serious leisure perspective. It differentiates between volunteering in leisure and volunteering as leisure, describes the populations served by the volunteers, and examines whether the residents’ involvement in volunteering is truly optimal.
The Villages provides its residents with a wide array of formal and informal media, most of which are digital. This chapter examines the content and usage of these media, delving into the attitudes of the residents towards them. Despite frequent criticism from residents about the media’s heavy emphasis on local "happy news," this chapter suggests that such a focus fosters a sense of a "bubble," which contributes positively to their well-being.
Living in a city for older adults inevitably involves facing and coping with the frequent deaths of neighbors, friends, and acquaintances, serving as a constant reminder of one’s mortality. Through the stories of three individuals, this chapter offers a glimpse into the experiences of dying, caregiving for the dying, and grieving in The Villages. It also contrasts the pervasive presence of death with the relative invisibility of the "fourth age."
Departing from the distinctions among retirement communities, "aging in place," and the newer concept of "aging in community," this chapter presents a definition and typology of retirement communities along with a brief history of these communities in the US. It then offers a literature review on key topics: (a) transitioning into a retirement community, (b) adjusting to and aging within a retirement community, and (c) the well-being of residents in these communities.
This chapter addresses the challenge of socially "starting from scratch" when moving into a community of approximately 150,000 older adults. It suggests that most residents integrate into overlapping place-, leisure-, and faith-based communities, and experience varying levels of psychological sense of community (PSOC). The chapter also explores the few instances where no PSOC was reported and examines the multiple tensions between different groups based on age, type of residency, and political orientation.
