Abstract Loneliness and social isolation as antecedents of cognitive decline have received substantial attention in recent research. This symposium addresses this year’s conference theme of aging in the “new normal”. The COVID-19 pandemic has highlighted the negative impacts of loneliness and social isolation on older adults’ health and wellbeing. This symposium includes studies that shed light on the relationships between loneliness, social isolation and cognitive health using a multidisciplinary approach, and provide recommendations and future directions for advancing this research area. The first presentation examines cardiovascular biomarkers as potential mechanisms that mediate the longitudinal relationship between loneliness and cognitive decline with the HRS dataset. The second presentation examines several social isolation indicators and their effects on cognitive decline in a Canadian longitudinal study. Using the US ADRC longitudinal study of aging, the third study shows the effect of loneliness on cognitive health in older adults pre- and post-onset of the COVID-19 pandemic. The symposium concludes with a literature review of the different measures employed to operationalize the constructs of loneliness, isolation, which resulted in heterogeneous study findings on their influences on the risk of developing dementia. This review calls for consistent measures to produce comparable evidence on the health consequences of loneliness and isolation. In all, this symposium reports and reviews the latest evidence on the association between social isolation, loneliness and cognitive health amidst the ongoing COVID-19 pandemic. It also echoes the conference theme of transforming disruption to opportunities in aging health service and research.

Abstract Background Social isolation and loneliness have each been associated with cognitive decline, but most previous research is limited to Western populations. This study examined the relationships of social isolation and loneliness on cognitive function among Chinese older adults. Methods This study used two waves of data (2011 and 2015) from the China Health and Retirement Longitudinal Study and analyses were restricted to those respondents aged 50 and older. Social isolation, loneliness, and cognitive function were measured at baseline. Follow-up measures on cognitive function were obtained for 7761 participants (mean age = 60.97, s.d. = 7.31; male, 50.8%). Lagged dependent variable models adjusted for confounding factors were used to evaluate the association between baseline isolation, loneliness, and cognitive function at follow-up. Results Loneliness was significantly associated with the cognitive decline at follow-up (episodic memory: β = −0.03, p < 0.01; mental status: β = −0.03, p < 0.01) in the partially adjusted models. These associations became insignificant after additional confounding variables (chronic diseases, health behaviors, disabilities, and depressive symptoms) were taken into account (all p > 0.05). By contrast, social isolation was significantly associated with decreases in all cognitive function measures at follow-up (episodic memory: β = −0.05, p < 0.001; mental status: β = −0.03, p < 0.01) even after controlling for loneliness and all confounding variables. Conclusions Social isolation is associated with cognitive decline in Chinese older adults, and the relationships are independent of loneliness. These findings expand our knowledge about the links between social relationships and the cognitive function in non-Western populations.

Abstract Social isolation and frailty are global public health issues that may lead to poor health outcomes. We tested the two following hypotheses: 1) changes in social isolation and frailty are associated with adverse health outcomes over two years, 2) the associations between social isolation and health vary across different levels of frailty. We estimated a series of latent growth models to test our hypotheses using data from the FRéLE longitudinal study among 1643 Canadian community-dwelling older adults aged 65 years and over. Missing data were handled by pattern mixture models with the assumption of missing not at random. We measured social isolation through social participation, social networks, and social support from different social ties. We assessed frailty using Fried’s criteria. Our results revealed that higher frailty at baseline was associated with a higher rate of comorbidity, depression, and cognitive decline over two years. Less social participation at baseline was associated with comorbidity, depression, and changes in cognitive decline. Less social support from friends, children, partner, and family at baseline was associated with comorbidity, cognitive decline, and changes in depression. Fewer contacts with grandchildren were related to cognitive decline over time. The associations of receiving less support from partner with depression and participating less in social activities with comorbidity, depression, and cognitive decline were higher among frail or prefrail than robust older adults over time. This longitudinal study suggests that intimate connectedness and social participation may ameliorate health status in frail older populations, highlighting the importance of age-friendly city policies.

Negative Impacts

The COVID-19 pandemic is associated with several short- and long-term negative impacts on the well-being of older adults. Physical distancing recommendations to reduce transmission of the SARS-CoV2-19 virus increase the risk of social isolation and loneliness, which are associated with negative outcomes including anxiety, depression, cognitive decline, and mortality. Taken together, social isolation and additional psychological impacts of the pandemic (e.g., worry, grief) underscore the importance of intervention efforts to older adults. This narrative review draws upon a wide range of evidence to provide a comprehensive overview of appropriate remotely-delivered interventions for older adults that target loneliness and psychological symptoms. These include interventions delivered by a range of individuals (i.e., community members to mental health professionals), and interventions that vary by implementation (e.g., self-guided therapy, remotely-delivered interventions via telephone or video call). Recommendations to overcome barriers to implementation and delivery are provided, with consideration given to the different living situations.

Abstract Rural-urban disparities in cognitive health outcomes, such as greater prevalence of cognitive decline among rural-dwelling older adults, have been linked to inequity in access to care. However, few studies have demonstrated whether longitudinal increased access to care may mitigate such disparities. This paper presents data from ongoing systematically collected behavioral health data on new and returning patients at an interdisciplinary geriatrics clinic at the University of Alabama Medical Center. The aim of this study was to determine baseline predictors of cognitive change across three annual visits (n = 42, mean age of 75.63 years (SD = 9.15)). Adjusting for baseline cognitive status, baseline subjective health literacy, and baseline depression and anxiety, results from a univariate ANCOVA showed that age at first visit (B = -.024, 95% CI [-.041, -.008], t(35) = -2.990, p = .005) and rural-urban status (B = .555, 95% CI [.123, .988], t(35) = 2.608, p = .013) predicted cognitive change at timepoint three (T3). Specifically, individuals from rural areas were less likely to experience cognitive decline and scored .555 points better than individuals from urban areas on cognitive screeners at T3 compared with baseline cognitive status. These results suggest that increased access to and utilization of care may ameliorate traditional disparate rates of cognitive decline between rural- and urban-dwelling older adults. Moreover, behavioral health screenings in primary geriatrics clinic care may help identify patient cognitive needs and facilitate integrated care through combined medical, pharmacological, and behavioral interventions to promote positive cognitive health outcomes.
