Recent research has documented associations between subjective health ratings and objective indicators of disease and death. Less is known about relations between subjective health ratings and level of cognitive performance in older adults. In this study, we explored whether subjective health ratings are related to episodic memory performance, both concurrently and across a three-year longitudinal interval. Persons aged 75–84 years, and participating in the Swedish Kungsholmen Project ( n = 105) or the Canadian Victoria Longitudinal Study ( n = 71), were examined. Results showed that in both samples, while the cross-sectional relationship was non-significant, longitudinal change in perceptions of subjective health were related to change in episodic memory performance. Next, the two samples were combined in additional analyses. Here, results further revealed that the associations between longitudinal change in subjective health and memory performance generalized across samples independently of demographic, changing physical health status, and subjective memory decline differences. Thus, the present findings suggest that subjective health may be added to the growing number of individual-difference variables that are predictive of episodic memory change in very old age.

ABSTRACT Objectives: The relationship between wisdom and fluid intelligence (Gf) is poorly understood, particularly in older adults. We empirically tested the magnitude of the correlation between wisdom and Gf to help determine the extent of overlap between these two constructs. Design: Cross-sectional study with preregistered hypotheses and well-powered analytic plan (https://osf.io/h3pjx). Setting: Memory and Aging Center at the University of California San Francisco, located in the USA. Participants: 141 healthy older adults (mean age = 76 years; 56% female). Measurements: Wisdom was quantified using a well-validated self-report-based scale (San Diego Wisdom Scale or SD-WISE). Gf was assessed via composite measures of processing speed (Gf-PS) and executive functioning (Gf-EF). The relationships of SD-WISE scores to Gf-PS and Gf-EF were tested in bivariate correlational analyses and multiple regression models adjusted for demographics (age, sex, and education). Exploratory analyses evaluated the relationships between SD-WISE and age, episodic memory performance, and dorsolateral and ventromedial prefrontal cortical volumes on magnetic resonance imaging. Results: Wisdom showed a small, positive association with Gf-EF (r = 0.181 [95% CI 0.016, 0.336], p = .031), which was reduced to nonsignificance upon controlling for demographics, and no association with Gf-PS (r = 0.019 [95% CI −0.179, 0.216], p = .854). Wisdom demonstrated a small, negative correlation with age (r = −0.197 [95% CI −0.351, −0.033], p = .019), but was not significantly related to episodic memory or prefrontal volumes. Conclusions: Our findings indicate that most of the variance in wisdom (>95%) is unaccounted for by Gf. The independence of wisdom from cognitive functions that reliably show age-associated declines suggests that it may hold unique potential to bolster decision-making, interpersonal functioning, and other everyday activities in older adults.

The Relationship

Abstract Cognitive health is a rising public health concern in the U.S. Currently, approximately 5.7 million older adults suffer from Alzheimer’s disease (AD), and by the year 2050 this number is expected to increase to 14 million. Subjective memory complaints (SMC) are shown to be an early indicator of cognitive decline, and accordingly included as a clinical criterion for diagnoses of MCI, an indicator of pre-dementia states, and a research criterion for AD diagnoses. Among older adults, depressive symptoms hinder the accuracy of memory self-ratings. However, there has yet to be consensus regarding the nature of how depressive symptoms may condition the relationship between SMC and cognitive performance. The aims of the present study are to both investigate whether SMC is related to episodic memory and to determine whether depressive symptoms act as a moderator for the relationship between SMC and episodic memory among older adults. This research used nationally representative sample of 8,123 older adults aged 65 and older who completed the Leave Behind Questionnaire in the 2012 and 2014 waves of the Health and Retirement Study. Linear regression was performed and results showed that there was a significant main effect of SMC on episodic memory performance, in that older adults with increased SMC have worse episodic memory. There was also a significant moderating effect of depressive symptoms, in that depressive symptoms cause older adults to underestimate their memory abilities. In order to use SMC as a tool for early detection efforts it is critical to understand these complex relationships.

Numeric Information

This chapter reviews the episodic memory difficulties typically encountered by older adults. It presents data that demonstrates that mnemonic interventions can improve episodic memory in the elderly, though such improvements often do not transfer broadly and do not result in improvements in the area of subjective memory assessment. It then presents three approaches to improving episodic memory for numeric information, each based upon a different approach. These approaches demonstrate: (a) that a mnemonic targeted at numeric information can improve number recall; (b) that self-generated strategies can improve recall at nearly the same level as a targeted mnemonic; and (c) that episodic memory can be converted into procedural memory, though this approach did not demonstrate improved episodic memory performance. Future directions for memory remediation are discussed, based upon research findings to date.

Component Processes

To bridge the gap between naturalistic and laboratory assessments of episodic memory, we designed time- and content-matched real-world and virtualized versions of the same tour event. In younger and older adults, we investigated objective and subjective aspects of recollection for event features using a verbal true/false test common to both event conditions. Using a data-driven multivariate analysis blind to the age groups and event conditions, we found that discrimination of altered details explained most of the variance in objective memory performance. There was an advantage for real-world over laboratory encoding on this dimension for both age groups. Similarly, real-world encoding elicited higher scores on a dimension defined by subjective re-experiencing. However, real-world (but not laboratory) encoding decoupled objective and subjective memory in older adults, who reported similar rates of subjective recollection as younger adults despite having objectively poorer discrimination accuracy. This interaction suggests that episodic memory for real-world versus laboratory events recruit distinct component processes.

The Impact

Evidence concerning the impact of fear of memory decline on health-related outcomes is limited. To determine the relationship between fear-avoidance of memory decline, quality of life and subjective memory in older adults using a novel scale to measure fear of memory decline. Sixty-seven older adults (59-81 years) completed a 23-item self-report questionnaire designed to capture experiential, cognitive and behavioral components of fear of memory decline, known as the fear and avoidance of memory decline (FAM) scale. Memory performance was assessed using the Wechsler Memory Scale (WMS-IV) and the Memory Failures Scale (MFS). General anxiety was assessed using the Depression, Anxiety and Stress Scales (DASS) and the Geriatric Anxiety Inventory (GAI). Quality of life was assessed using the Older Person’s Quality of Life scale (OPQOL-35). The FAM scale demonstrated good reliability and validity. Three latent factors were observed including: (1) fear-avoidance, (2) problematic beliefs and (3) resilience. After adjusting for age, education, memory performance and general anxiety, higher fear-avoidance predicted lower quality of life (p=.021) and increased memory failures (p=.022). Increased fear of memory decline predicts lower quality of life and subjective memory failures in healthy older adults. Based on these findings, we propose a preliminary fear-avoidance model that explains the development and maintenance of dementia-related functional disability in terms of psychological processes.

Abstract Social engagement may confer cognitive benefits in older adulthood, but studies have typically been restricted to largely non-Hispanic White (NHW) samples. Levels of social engagement vary across race such that NHW report larger social networks, more frequent participation in social activities, and greater social support than non-Hispanic Blacks (NHB). Associations between social engagement and cognition may also vary by race, but research is sparse. The current cross-sectional study examined associations between different aspects of social engagement and episodic memory performance, as well as interactions between social engagement and race among NHB and NHW participants in the Michigan Cognitive Aging Project (N = 247; 48.4% NHB; age = 64.19 ± 2.92). Social engagement (network size, activities, support) was self-reported. Episodic memory was a z-score composite of immediate, delayed, and recognition trials of a list-learning task. Separate hierarchical linear regression models quantified interactions between race and each of the three social engagement variables on episodic memory, controlling for sociodemographics, depressive symptoms, and health conditions. Results showed a main effect of more frequent social activity on better episodic memory, as well as an interaction between race and social support indicating a significant positive association in NHB but not NHW. These preliminary findings suggest that participating in social activities may be equally beneficial for episodic memory across NHB and NHW older adults and that social support may be particularly beneficial for NHB. Future research is needed to determine the potential applications of these results in reducing cognitive inequalities through the development of culturally-relevant interventions.

Abstract During the Covid-Crisis, stereotypes of older adults as helpless and vulnerable were spread, and intergenerational conflict was stirred more or less openly. We thus focused on perceived ageism during the crisis and its effects on well-being and health of older adults. Since views on aging are multifaceted and can be both, risk and resource for individual development, we assessed people’s self-perceptions of aging (SPA) as social loss, continued growth and physical decline and subjective age (SA). We hypothesized that people with SPA of social loss and physical decline would be more susceptible to negative effects of perceived ageism, whereas those with SPA of continued growth and younger SA would be less affected. NT1 = 611 community-dwelling adults aged 60 – 98 (Mage = 69.92 years) were recruited in June 2020 online and via phone in Luxembourg. In September 2020, participants will be contacted again for a follow-up. Analyses with cross-sectional data show that participants who felt more discriminated reported lower life satisfaction after the onset of the crisis (r = -.35) and worse subjective health (r = -.14). SPA of social loss and higher SA increased the negative effect of ageism on well-being (beta = -.57) and subjective health (beta = -.53), respectively. Our results point to mid- and long-term consequences of age discriminatory and stereotype-based crisis communication for the well-being of older adults and the importance of individual SPA in critical situations.

Stress Memory

Abstract Objective: Stress is a risk factor for numerous negative health outcomes, including cognitive impairment in late-life. The negative association between stress and cognition may be mediated by depressive symptoms, which separate studies have identified as both a consequence of perceived stress and a risk factor for cognitive decline. Pathways linking perceived stress, depressive symptoms, and cognition may be moderated by sociodemographics and psychosocial resources. The goal of this cross-sectional study was to identify modifying factors and enhance understanding of the mechanisms underlying the stress–cognition association in a racially and ethnically diverse sample of older adults. Method: A linear regression estimated the association between perceived stress and episodic memory in 578 older adults (Mage = 74.58) in the Washington Heights-Inwood Columbia Aging Project. Subsequent models tested whether depressive symptoms mediated the stress–memory relationship and whether sociodemographics (gender, race, and ethnicity) or perceived control moderated these pathways. Results: Independent of sociodemographics and chronic diseases, greater perceived stress was associated with worse episodic memory. This relationship was mediated by more depressive symptoms. Higher perceived control buffered the association between stress and depressive symptoms. There was no significant moderation by gender, race, or ethnicity. Conclusion: Depressive symptoms may play a role in the negative association between perceived stress and cognition among older adults; however, longitudinal analyses and studies using experimental designs are needed. Perceived control is a modifiable psychological resource that may offset the negative impact of stress.
