COVID-19, loneliness, social isolation and risk of dementia in older people: a systematic review and meta-analysis of the relevant literature

Social isolation and loneliness in non-communicable chronic diseases: Impact of COVID-19 pandemic, population aging and technological progress

AIMS

Social isolation and loneliness have increasingly emerged as closely linked to onset and progression of non-communicable chronic diseases (NCDs). The aim of this review is to highlight the importance of addressing social isolation in the prevention and management of NCDs such as obesity, type 2 diabetes, and cardiovascular diseases in order to hinder their development and improve their outcomes.

DATA SYNTHESIS

Social isolation and loneliness affect a significant portion of the older adult population, due to decrease in social interactions, chronic illnesses and sensory impairments. However, many other vulnerable populations may experience social isolation because of psychiatric or disabling health conditions, substances abuse, low socioeconomic status, unemployment and belonging to ethnic or marginalized minorities. The unprecedented COVID-19-related social distancing can be taken as a proof-of-concept of the detrimental role of poor interactions in NCDs prevention and management not only at individual level but also in a public health perspective. Indeed, social isolation has been linked to unhealthy lifestyle choices, disrupted sleep quality, low utilization of healthcare, preventive services and adherence to treatments. Underlying mechanisms like inflammation and stress responses may also play a role in the association between social isolation and worse NCDs outcomes.

CONCLUSIONS

Social isolation negatively impacts on the development, progression and management of NCDs. Effective interventions for social isolation should address both societal factors and healthcare-related needs. To counteract the detrimental effects of social distancing during COVID-19 pandemic, the use of telemedicine was implemented. However, telemedicine is not always available, and legislative and age-related barriers persist.

Social Frailty and Social Isolation in the Context of Dementia: A Simultaneous Concept Analysis

OBJECTIVES

Early management of risk factors related to social health such as social frailty and social isolation could modify the progression of dementia and reduce its impact on people with dementia. However, due to overlapping definitions and interchangeable use of measurement tools, the precise distinction between these two concepts is unclear. This simultaneous concept analysis aimed to examine the definitions and interrelationships between the concepts of social frailty and social isolation within the context of dementia.

METHODS

The simultaneous concept analysis method developed by Haase et al. was employed. A literature search was conducted across six databases (Ovid Medline, CINAHL, PsycINFO, Scopus, Embase and Cochrane Library) to retrieve original research, review and theoretical papers, published in English. Data from the literature was synthesised and analysed thematically following Braun and Clarke's six steps.

RESULTS

The attributes of concepts of social frailty and social isolation overlap, including being alone and having limited or less social activities, engagements or interactions. The specific attributes of social frailty are financial difficulties and less talk while social isolation is distinctly marked by a lack of social networks or social relationships. Socio-economic welfare is a specific antecedent of social frailty, while decreased access to social resources and lower social well-being are distinctive consequences of social isolation. Cognitive decline and dementia are distinctive antecedents of social isolation; however, they also exist as shared consequences of both social frailty and social isolation.

CONCLUSIONS

This simultaneous concept analysis clarified the similarities and differences between social frailty and social isolation in the context of dementia. A clearer understanding of the interrelationships between social frailty and social isolation and distinct and overlapping characteristics of them will support strategies to comprehensively address social health issues experienced by people with dementia.

The association of pre-COVID-19 social isolation and functional social support with loneliness during COVID-19: a longitudinal analysis of the Canadian Longitudinal Study on Aging

OBJECTIVES

We evaluated the association between two measures of social connection prior to COVID-19-social isolation and functional social support-and loneliness during the pandemic.

METHOD

The study was a retrospective longitudinal analysis of 20,129 middle-aged and older adults enrolled in the Canadian Longitudinal Study on Aging (CLSA). We drew upon two waves of CLSA data spanning three years and the supplemental COVID-19 Questionnaire Study of eight months to conduct our analysis.

RESULTS

Social isolation prior to COVID-19 was associated with loneliness during COVID-19 only among persons who were lonely before the pandemic (adjusted odds ratio [aOR]: 1.17; 95% confidence interval [CI]: 1.02, 1.35). Higher functional social support prior to COVID-19 was inversely associated with loneliness during the pandemic, when adjusting for pre-COVID-19 loneliness (aOR: 0.37; 95%CI: 0.34, 0.41) and when assessing incident loneliness during the pandemic (adjusted relative risk: 0.59; 95% CI: 0.55, 0.63).

CONCLUSION

Policies are needed to identify people who are both socially isolated and lonely, and provide them with functional social support, to prevent worsening loneliness during public health crises.

"Loneliness is a sad disease": oldest old adults' empirical definition of loneliness and social isolation from a mixed-method study in Northern Italy

BACKGROUND

Loneliness and social isolation can occur at any stage of life, but some predictors may be more common among older adults. Due to growing population ageing, loneliness and social isolation are relevant social issues. Many studies apply the main definitions of loneliness and social isolation offered by the literature without considering how individual representations, socio-cultural context and the culture of care may influence their perception. This study wishes to fill in these literature gaps by analysing empirical definitions of loneliness and social isolation arising from a mixed-gender randomized sample of Italian oldest old people.

METHODS

Between January and March 2019, 132 older people, most aged 80+, living in a northern Italian town, were asked to answer a questionnaire and a semi-structured interview. According to a mixed-method analysis the definitions of loneliness and social isolation were analysed by respondents' gender, living arrangement (e.g., living alone or with partners or other people), and years of education to find possible associations to the meanings attributed to the two concepts.

RESULTS

The sample was gender-balanced and mid-low educated; more than one fourth of respondents lived alone. The results underline how the empirical definitions of loneliness and social isolation are closer to each other than the academic ones. The two concepts are often perceived by participants as distinct, but they are strongly interconnected so that they can be used interchangeably by older Italian people. The two main themes identified by the analysis are loneliness as "death" and social isolation as "guilt". In the respondents' opinion, the main loneliness driver is the loss of loved, close persons, while social isolation is driven by disability. Age, educational level, and living arrangements did not influence the meanings attributed to social isolation. On the contrary, living arrangement (P = 0.002) and educational level (p = 0.023) seem to influence the empirical definitions of loneliness.

CONCLUSION

The knowledge of the meanings that oldest old give to the two concepts may inspire advanced intervention aimed at buffering the psychological and social consequences of loneliness and social isolation in the older population.

Characteristics of Coping with Loneliness and the Influence of Living Arrangements Among Older Adults: Findings from a Comparative Qualitative Study

Loneliness among older adults is a well-known public health issue that became significantly apparent in the post-Covid-19 era. Our qualitative study examined and compared the perspectives of thirty-one older adults toward the factors that intensified or reduced loneliness. Five themes emerged from the analysis: emotional vs. social loneliness; the impact of health conditions on loneliness; the effect of socioeconomic status on loneliness; the role of family links; and the role of social networks . Findings show that effectively reducing loneliness requires a better understanding of how social networks differ based on sociodemographic elements and dominant cultural values. .

Loneliness Gets Under the Skin: A Scoping Review Exploring the Link Between Loneliness and Biological Measures of Inflammation

BACKGROUND

Research suggests that systemic inflammation may link loneliness to adverse health outcomes, yet there is a gap in comprehensively reviewing recent evidence on the relationship between loneliness and biological measures of inflammation in adults. This scoping review synthesizes current research to address the question: Is there a definitive link between loneliness and biological markers of inflammation in adults?

METHODS

Following the methods outlined by Arksey and O'Malley, we developed a protocol, defined our research question, and systematically searched PubMed, CINAHL, Embase, and Scopus for English-language studies conducted from 2018 to 2023 exploring the relationship between loneliness and biomarkers of inflammation in adults.

RESULTS

Twelve studies meeting the inclusion criteria displayed heterogeneity in terms of sample characteristics, loneliness scales, and inflammatory biomarkers. The UCLA Loneliness Scale, in various forms, emerged as the predominant tool for measuring loneliness, while C-reactive protein and interleukin-6 were the most frequently evaluated inflammatory biomarkers. Notably, all 12 studies reported an association between loneliness and at least 1 biological marker of inflammation.

CONCLUSION

Research consistently associates loneliness with poor health outcomes in aging adults, but the underlying mechanisms remain unclear. This scoping review suggests that inflammation may serve as a pathway linking loneliness to adverse health outcomes. However, the variability across studies highlights the need for standardized measurement methods and a consideration of both the duration and extent of loneliness. Enhancing our understanding of how loneliness affects systemic inflammation may help clarify why loneliness is associated with negative health outcomes.

Racial Differences in the Association Between Loneliness and Cognitive Impairment Among Older Black and White Men

BACKGROUND

Loneliness is a biopsychosocial stressor linked to poor health outcomes including dementia. Few studies have focused on this association among men and even fewer have examined racial disparities in loneliness and cognitive functioning among this group. The purpose of this study was to examine racial differences in the association between loneliness and cognitive functioning among men in the 2016 wave of the Health and Retirement Study.

METHODS

This cross-sectional study included Black and White men who completed the core questionnaire and the Leave Behind Questionnaire (n = 2 227). Any cognitive impairment was the primary outcome and was measured by a dichotomous variable derived from a modified version of the Telephone Interview for Cognitive Status. Loneliness was the primary independent variable and was derived from the 3-item University of California, Los Angeles (UCLA) Loneliness Scale. Modified Poisson regression models with robust standard errors were estimated to generate prevalence ratios (PRs) and corresponding 95% confidence intervals (CIs).

RESULTS

Black men comprised 18.4% of the study sample; however, the proportion of this group with scores indicating cognitive impairment (35.9%) doubled the corresponding percentage of white men (17.6%). Findings from race-stratified modified Poisson regression models indicated that loneliness was associated with a higher prevalence of any cognitive impairment for White men (PR = 1.24, CI: 1.05-1.47), but not for Black men (PR = 0.92, CI: 0.73-1.16).

CONCLUSIONS

Our results underscore the complexity of race when investigating the association between loneliness and cognitive impairment among older men. Additional studies are needed to further examine how loneliness may have racially distinct implications for cognitive outcomes among the population.

A Meta-analysis of Loneliness and Risk of Dementia using Longitudinal Data from >600,000 Individuals

Loneliness is one critical risk factor for cognitive health. Combining data from ongoing aging studies and the published literature, we provided the largest meta-analysis on the association between loneliness and dementia (k = 21 samples, N = 608,561) and cognitive impairment (k = 16, N = 103,387). Loneliness increased risk for all-cause dementia (HR = 1.306, 95% CI [1.197,1.426]), Alzheimer's disease (HR = 1.393, 95% CI [1.290,1.504]; k = 5), vascular dementia (HR = 1.735, 95% CI [1.483,2.029]; k = 3), and cognitive impairment (HR = 1.150, 95% CI [1.113,1.189]). The associations persisted when models controlled for depression, social isolation, and/or other modifiable risk factors for dementia. The large heterogeneity across studies was partly due to differences in loneliness measures and ascertainment of cognitive status. Results underscored the importance to further examine type/sources of loneliness and cognitive symptoms to develop effective interventions that reduce the risk of dementia.

Racial and ethnic disparities in social isolation and 11-year dementia risk among older adults in the United States

AIMS

Social isolation has been implicated in the development of cognitive impairment, but research on this association remains limited among racial-ethnic minoritized populations. Our study examined the interplay between social isolation, race-ethnicity and dementia.

METHODS

We analyzed 11 years (2011-2021) of National Health and Aging Trends Study (NHATS) data, a prospective nationally representative cohort of U.S. Medicare beneficiaries aged 65 years and older. Dementia status was determined using a validated NHATS algorithm. We constructed a longitudinal score using a validated social isolation variable for our sample of 6,155 community-dwelling respondents. Cox regression determined how the interaction between social isolation and race-ethnicity was associated with incident dementia risk.

RESULTS

Average longitudinal frequency of social isolation was higher among older Black (27.6%), Hispanic (26.6%) and Asian (21.0%) respondents than non-Hispanic White (19.1%) adults during the 11-year period (t = -7.35, p < .001). While a higher frequency of social isolation was significantly associated with an increased (approximately 47%) dementia risk after adjusting for sociodemographic covariates (adjusted hazard ratio [aHR] = 1.47, 95% CI [1.15, 1.88], p < .01), this association was not significant after adjusting for health covariates (aHR = 1.21, 95% CI [0.96, 1.54], p = .11). Race-ethnicity was not a significant moderator in the association between social isolation and dementia.

CONCLUSIONS

Older adults from racial-ethnic minoritized populations experienced a higher longitudinal frequency of social isolation. However, race-ethnicity did not moderate the positive association observed between social isolation and dementia. Future research is needed to investigate the underlying mechanisms contributing to racial-ethnic disparities in social isolation and to develop targeted interventions to mitigate the associated dementia risk.

Loneliness, cerebrovascular and Alzheimer's disease pathology, and cognition

INTRODUCTION

Loneliness has a rising public health impact, but research involving neuropathology and representative cohorts has been limited.

METHODS

Inverse odds of selection weights were generalized from the autopsy sample of Rush Alzheimer's Disease Center cohorts (N = 680; 89 ± 9 years old; 25% dementia) to the US-representative Health and Retirement Study (N = 8469; 76 ± 7 years old; 5% dementia) to extend external validity. Regressions tested cross-sectional associations between loneliness and (1) Alzheimer's disease (AD) and cerebrovascular pathology; (2) five cognitive domains; and (3) relationships between pathology and cognition, adjusting for depression.

RESULTS

In weighted models, greater loneliness was associated with microinfarcts, lower episodic and working memory in the absence of AD pathology, lower working memory in the absence of infarcts, a stronger association of infarcts with lower episodic memory, and a stronger association of microinfarcts with lower working and semantic memory.

DISCUSSION

Loneliness may relate to AD through multiple pathways involving cerebrovascular pathology and cognitive reserve.

HIGHLIGHTS

Loneliness was associated with worse cognition in five domains. Loneliness was associated with the presence of microinfarcts. Loneliness moderated cognition-neuropathology associations. Transportability methods can provide insight into selection bias.

Cognition and Activity of Daily Living Function in people with Parkinson's disease

The ability to perform activities of daily living (ADL) function is a multifaceted construct that reflects functionality in different daily life situations. The loss of ADL function due to cognitive impairment is the core feature for the diagnosis of Parkinson's disease dementia (PDD). In contrast to Alzheimer's disease, ADL impairment in PD can be compromised by various factors, including motor and non-motor aspects. This narrative review summarizes the current state of knowledge on the association of cognition and ADL function in people with PD and introduces the concept of "cognitive ADL" impairment for those problems in everyday life that are associated with cognitive deterioration as their primary cause. Assessment of cognitive ADL impairment is challenging because self-ratings, informant-ratings, and performance-based assessments seldomly differentiate between "cognitive" and "motor" aspects of ADL. ADL function in PD is related to multiple cognitive domains, with attention, executive function, and memory being particularly relevant. Cognitive ADL impairment is characterized by behavioral anomalies such as trial-and-error behavior or task step omissions, and is associated with lower engagement in everyday behaviors, as suggested by physical activity levels and prolonged sedentary behavior. First evidence shows that physical and multi-domain interventions may improve ADL function, in general, but the evidence is confounded by motor aspects. Large multicenter randomized controlled trials with cognitive ADL function as primary outcome are needed to investigate which pharmacological and non-pharmacological interventions can effectively prevent or delay deterioration of cognitive ADL function, and ultimately the progression and conversion to PDD.

Exploring the social and cultural aspects of Chinese family caregivers' experience as they support loved ones with dementia transitioning into nursing homes: a qualitative study protocol

INTRODUCTION

Asian American caregivers supporting loved ones with dementia experience greater burden and more stress than other racial/ethnic groups, warranting the need for more culturally and linguistically appropriate formal support, such as in nursing homes. Transitioning loved ones into nursing homes with dementia care units is a complex process that can be impacted by a multitude of factors. Employing several established frameworks, including the socioecological model, this qualitative study will focus on the largest Asian American subgroup (people of Chinese descent) and explore the experience of family caregivers as they support the transition of their loved ones with dementia into nursing homes in the USA. Our focus will be on the nuanced influences of the Chinese language and culture and COVID-19-related social isolation and racial discrimination.

METHODS AND ANALYSIS

Recruitment will take place starting in January 2024. Current or former Chinese caregivers for Chinese loved ones with dementia, able to communicate in Mandarin Chinese or English, and currently residing in the USA will be eligible. Key informants with intimate understanding and experience with this population will also be included. Data will be collected through 2024 using semistructured, in-depth interviews with each participant. Depending on participants' preferences, interviews will be conducted in either Mandarin Chinese or English and either in person, via Zoom or by phone. Interviews will be transcribed verbatim. Iterative thematic analysis will be employed. A coding structure will be developed based on interview questions and themes and patterns that are revealed through data immersion. Transcripts, prepared in their original language, will be dual-coded by bilingual researchers using NVivo 14. Consensus summaries of themes will be prepared. Relevant direct quotes for each thematic area will be identified (those in Chinese will be translated into English) and cited in reports and manuscripts.

ETHICS AND DISSEMINATION

The study is approved by the UMass Chan Medical School Institutional Review Board (ID: STUDY00001376). Findings will be published in peer-review journals following the consolidated criteria for reporting qualitative research.

Needs of social isolation, loneliness, and intergenerational interventions in the United States: a scoping review

Social isolation and loneliness are major health concerns for older adults in the United States. This scoping review examines the effectiveness of intergenerational interventions aimed at reducing social isolation and loneliness among older adults in the United States, specifically through programs that engage university students from healthcare-related fields in one-on-one settings with older adults, as reports of lacking geriatric training of healthcare students causes older adult neglect to persist in the healthcare workforce. The importance of addressing these issues is underscored by significant health risks and substantial economic burdens, with social isolation and loneliness potentially increasing mortality and costing Medicare an estimated $6.7 billion annually. Covering literature from 2010 to 2022, this review critically assesses the role of such interventions in fostering social connections and improving both physical and mental health outcomes. Despite the positive preliminary results indicating significant reductions in loneliness and enhancements in social networks among participants, the review highlights considerable gaps in current research, particularly in structured intervention curricula, demographic reporting and detailed intervention descriptions. This underscores the need for more rigorous and standardized research methodologies to better understand the effectiveness and potential of intergenerational programs as interventions against the detrimental effects of social isolation and loneliness among older adults.

A translational neuroscience perspective on loneliness: Narrative review focusing on social interaction, illness and oxytocin

This review addresses key findings on loneliness from the social, neurobiological and clinical fields. From a translational perspective, results from studies in humans and animals are included, with a focus on social interaction, mental and physical illness and the role of oxytocin in loneliness. In terms of social interactions, lonely individuals tend to exhibit a range of abnormal behaviors based on dysfunctional social cognitions that make it difficult for them to form meaningful relationships. Neurobiologically, a link has been established between loneliness and the hypothalamic peptide hormone oxytocin. Since social interactions and especially social touch regulate oxytocin signaling, lonely individuals may have an oxytocin imbalance, which in turn affects their health and well-being. Clinically, loneliness is a predictor of physical and mental illness and leads to increased morbidity and mortality. There is evidence that psychopathology is both a cause and a consequence of loneliness. The final section of this review summarizes the findings from social, neurobiological and clinical perspectives to present a new model of the complex construct of loneliness.

Fostering belonging and social connectedness in nursing: Evidence-based strategies: A discussion paper for nurse students, faculty, leaders, and clinical nurses

BACKGROUND

The phenomenon of loneliness among healthcare providers, particularly nurses, has garnered increasing attention due to its detrimental effects on individual well-being and professional retention. The isolation experienced by nurses has been linked to heightened turnover rates and intentions to leave the profession, posing significant challenges to healthcare systems globally. Recognizing loneliness as an epidemic in 2023, the U.S. Surgeon General highlighted the urgency of addressing this issue within the healthcare workforce.

PURPOSE

This paper explores evidence-based strategies to mitigate loneliness and promote social connectedness among nurses, drawing insights from various stakeholders. It aims to offer actionable recommendations to enhance the nursing experience and retain professionals in the field.

DISCUSSION

Strategies include peer support programs, mentorship initiatives, wellness activities, and fostering open communication. Leveraging technology for virtual connections is also highlighted, especially in remote work scenarios.

CONCLUSION

A holistic approach is vital, combining individual, interpersonal, and systemic interventions to combat nurse loneliness. Prioritizing social connectedness fosters a supportive work environment, benefiting both nurses and patient care quality.

Risk factors associated with loneliness among mexican-origin adults in southern Arizona

This study examines factors associated with symptoms of loneliness among a sample (n = 213) of mostly Mexican-origin adults at risk of chronic diseases in Southern Arizona's Pima, Yuma, and Santa Cruz counties. It uses baseline data from a community-based participatory research partnership and multinominal logistic regression models. Controlling for chronic diseases and sociodemographic characteristics, perceived social support and hope exhibit negative main effects on loneliness when comparing individuals who experienced loneliness for 5-7 days in the preceding week with those who did not encounter such feelings during the same period (adjusted odds ratio, AOR = 0.49 and 0.47; 95% confidence interval, CI = 0.34-0.73 and 0.29-0.75, respectively). However, when considered together, perceived social support and hope display a positive and statistically significant combined effect on loneliness (AOR = 1.03; 95% CI = 1.01-1.06). Holding all covariates constant, individuals reporting loneliness for 5-7 days exhibit a relative risk ratio of 1.24 (95% CI = 1.06-1.46) for a one-unit increase in physical problem severity compared to those who do not experience loneliness. Moreover, being 65 years old or older (AOR = 0.16, 95% CI = 0.03-0.84), and having been born in Mexico and lived in the US for less than 30 years (AOR = 0.12, 95% CI = 0.02-0.74) are associated with negative main effects on loneliness when comparing individuals who experienced loneliness 1-2, and 5-7 days in the preceding week with those who did not feel loneliness during the same timeframe, respectively. Recognizing the crucial role of loneliness in shaping health outcomes for Mexican-origin adults, our findings underscore the significance of fostering supportive environments that not only enhance well-being but also cultivate robust community bonds within the US-Mexico border region.

Hearing loss and psychosocial outcomes: Influences of social emotional aspects and personality

The aim of this study was to examine the effects of social isolation, loneliness, anxiety, depression, higher stress, and memory complaints interacting with personality traits as a function of hearing loss. Personality traits have previously been shown to correlate with anxiety and depression, as well as hearing loss, suggesting an effect of personality on the relationship between social emotional outcomes and hearing loss. A cross-sectional survey including validated screening measures was anonymously administered. Measures included personality (Big Five Index-2 Extra-Short Form), stress (Perceived Stress Scale), anxiety and depression (Patient Health Questionnaire for Depression and Anxiety), loneliness (Three-Item Loneliness Scale), social engagement (Lubben Social Network Scale-6), and self-perceived memory complaints (Subjective Cognitive Function). Eight hundred and ninety-one responses were obtained from adults between the ages of 18 and 90 years old (M = 50 years old). Hearing loss was positively correlated with subjective memory complaints only when not accounting for demographic variables, personality traits, psychosocial outcomes, and social emotional outcomes. There were additive effects of hearing loss and negative emotionality on increases in memory complaints in those who self-identified as maybe having hearing loss. Higher degrees of hearing loss also increased loneliness, with greater hearing loss negating the positive correlation between extraversion and social engagement. Overall, our results suggest that hearing loss significantly interacts with personality traits and other social emotional measures. Our results suggest that the impact of hearing loss on memory complaints, social isolation, and loneliness may differ across patients with hearing loss in comparison with those who think they maybe have hearing loss. Information from this study may provide insights for hearing healthcare and mental healthcare professionals to better serve persons with hearing loss who may require additional support or interventions.

Selected for Solitude: A Case Report of Loneliness

The U.S. Surgeon General, Vivek Murthy, recently declared loneliness a public health epidemic. For therapists, that is not likely to be a surprise: Loneliness is so common in people who seek therapy that it might be seen as the bread and butter of our work. Despite that, there has not been much serious examination of intrapsychic factors that may contribute to this painful condition. Public discourse has focused instead on cultural and societal causes of loneliness, and on practical steps that might be taken to decrease it. But practical advice is not always sufficient for people with longstanding loneliness. Longstanding loneliness may be fueled by intrapsychic dynamics and become embedded in character. In some cases, patients may relish companionship yet steadfastly avoid it in an attempt to master early childhood experiences of being emotionally neglected and deprived of love. They were starved of love as children and now choose to starve themselves in an unconscious attempt to master early deprivation by identifying with the aggressor. For patients like this, chronic loneliness may signal a certain kind of attachment disorder, for it is the visible sign of early attachment to a distant or rejecting parental figure. Loneliness of that kind can be a stubborn problem and one that poses a considerable therapeutic challenge.

"Connect Local": protocol for the evaluation of a codesigned whole of community approach to promote social connection in older adults

Background

There is wide acknowledgement in the literature that social connection is protective against loneliness and depression. More robust research, however, is needed to evaluate interventions that promote social connection. This protocol paper outlines the evaluation of a community-wide social connection program, Connect Local, in metropolitan Melbourne, Australia to support people 65 years and older to increase access to local community services/activities; and to ascertain impact on social connection, loneliness, depressive symptoms, physical and mental wellbeing, and use of health services.

Methods

A Type 1 Hybrid design, including program effectiveness, cost-effectiveness, and implementation evaluation of the Connect Local program, will be undertaken. Eighty-eight participants aged ≥65 years with one or more chronic health condition, who are also either experiencing or at risk of loneliness, social isolation and depressive symptoms will be invited to participate in the evaluation. Outcomes, measured at baseline, 3, 6 and 12 months, include loneliness, social isolation, depressive symptoms, social anxiety, goal attainment, wellbeing, quality of life and health care utilisation. A gender and age matched comparator group of 88 individuals will be recruited from outside the intervention local government area. Impact of the intervention on community service providers in the target region will be evaluated using mixed methods, where triangulation will be used to combine the qualitative and quantitative data using a deductive-simultaneous design. Changes in wellbeing and quality of life of community volunteers will also be measured. All groups will be interviewed to ascertain their experience and perceptions of the program. The economic evaluation will use a Social Return on Investment (SROI) approach, to include outcomes at the individual, community, and system levels. Implementation outcomes will consider Reach, Adoption, Feasibility, Acceptability, Appropriateness, Fidelity, and Sustainability of the intervention.

Discussion

This study will provide a better understanding of the impacts of a community-wide social connection approach in older adults, the community and broader system.

The Impact of Pandemic-Related Restrictions on Dementia Risk Factors in Older Adults

Adults aged 65+ are at highest risk for severe COVID-19 outcomes, and prior to the distribution of vaccines in the U.S., were strongly advised to quarantine at home to reduce risk of infection. This study examines how COVID-19 restrictions impacted various dementia risk factors and social determinants of health among older adults. Data came from the Systematic Multi-Domain Alzheimer's Risk Reduction Trial, a randomized controlled trial of a multi-domain intervention in higher-risk older adults (aged 70-89). A questionnaire was administered to participants (n = 156; 90.7% response rate) between May 2020 and March 2021. The data show a significant decline in social activity, physical activity, and mood among respondents. Compared to living with others, living alone was associated with worsened physical activity, diet, and subjective memory/thinking, adjusted for sex and age. These results suggest that the COVID-19 pandemic exacerbated several risk factors for dementia in older adults, particularly in those living alone.

Integrating Lifestyle Factor Science into Neuropsychological Practice: A National Academy of Neuropsychology Education Paper

OBJECTIVE

The primary aim of this paper is to review evidence and clinical implications related to lifestyle activities associated with promoting brain and cognitive health. Our review targets four key lifestyle factors: physical activity and exercise, social engagement, cognitively stimulating activity, and consuming Mediterranean-style diets.

METHOD

We conducted a critical review of the lifestyle factor literature in the four domains listed earlier. We contextualize this literature review by translating findings, when possible, into evidence-based recommendations to consider when providing neuropsychological services.

RESULTS

There is significant current evidence supporting the role of physical activity and exercise, social engagement, cognitively stimulating activity, and consuming Mediterranean-style diets on positive brain and cognitive health outcomes. While some null findings are present in all four areas reviewed, the weight of the evidence supports the notion that engaging in these activities may promote brain and cognitive functioning.

CONCLUSIONS

Clinical neuropsychologists can have confidence in recommending engagement in physical activity, social activity, and cognitively stimulating activity, and adhering to a Mediterranean-style diet to promote brain and cognitive health. We discuss limitations in existing lifestyle factor research and future directions to enhance the existing evidence base, including additional research with historically underrepresented groups and individuals with neurological conditions.

Factors associated with older adults' cognitive decline 6 months after gamma-variant SARS-CoV-2 infection

Background

Cognitive deficits are commonly reported after COVID-19 recovery, but little is known in the older population. This study aims to investigate possible cognitive damage in older adults 6 months after contracting COVID-19, as well as individual risk factors.

Methods

This cross-sectional study involved 70 participants aged 60-78 with COVID-19 6 months prior and 153 healthy controls. Montreal Cognitive Assessment-Basic (MoCA-B) screened for cognitive impairment; Geriatric Depression Scale and Geriatric Anxiety Inventory screened for depression and anxiety. Data were collected on demographics and self-reports of comorbid conditions.

Results

The mean age of participants was 66.97 ± 4.64 years. A higher proportion of individuals in the COVID group complained about cognitive deficits (χ2 = 3.574; p = 0.029) and presented with deficient MoCA-B scores (χ2 = 6.098, p = 0.014) compared to controls. After controlling for multiple variables, all the following factors resulted in greater odds of a deficient MoCA-B: COVID-19 6-months prior (OR, 2.44; p = 0.018), age (OR, 1.15; p < 0.001), lower income (OR, 0.36; p = 0.070), and overweight (OR, 2.83; p = 0.013). Further analysis pointed to individual characteristics in COVID-19-affected patients that could explain the severity of the cognitive decline: age (p = 0.015), lower income (p < 0.001), anxiety (p = 0.049), ageusia (p = 0.054), overweight (p < 0.001), and absence of cognitively stimulating activities (p = 0.062).

Conclusion

Our study highlights a profile of cognitive risk aggravation over aging after COVID-19 infection, which is likely mitigated by wealth but worsened in the presence of overweight. Ageusia at the time of acute COVID-19, anxiety, being overweight, and absence of routine intellectual activities are risk factors for more prominent cognitive decline among those infected by COVID-19.

Capturing postpandemic changes in research participants

The impact of the COVID-19 pandemic on physical and mental health hardly need be reiterated. Yet, there are likely other indirect aftereffects of COVID-19 infection in addition to the direct effects. This article aims to initiate a conversation regarding difficult-to-capture outcomes of the pandemic that are relevant to researchers who test human participants. These considerations encourage collection of additional measures when assessing pre- versus postpandemic patterns of behavior.

COVID-19 infection associated with poorer mental health in a representative population sample

OBJECTIVE

There is limited evidence of the direct effects of COVID-19 infection on mental health, and whether these are influenced by vaccination or physical health symptoms. We aimed to investigate the relationships of COVID-19 infection, current symptom presentation, and vaccination status with mental health symptoms in adults.

STUDY DESIGN AND SETTING

A cross-sectional sample of the Australian adult population that was representative by age, gender, and location was recruited through market research panels (N = 1407, 51.3% female, mean age 47.9 years). Hierarchical regression analyses were used to examine the associations of COVID-19 infection history and current COVID-19 symptoms with symptoms of depression (Patient Health Questionnaire-9), generalized anxiety (Generalized Anxiety Disorder-7) and social anxiety (Mini-Social Phobia Inventory).

RESULTS

COVID-19 infection was associated with significantly higher depression and anxiety symptoms, but only in those who were not fully vaccinated. Current experience of COVID-related symptoms was associated with significantly higher depression and anxiety symptoms, and attenuated the direct effect of infection on mental health outcomes to non-significance.

CONCLUSION

COVID-19 infection may be associated with increased mental health symptoms. However, the effects of infection on mental health were primarily evident in those who were not fully vaccinated and were explained by greater physical health problems associated with COVID-19 infection. The findings reinforce the efficacy of vaccination for reducing physical and mental health symptoms following infection.

Social Activity and Cognitive Decline in Older Residents of Long-Term Care Facilities: A Cohort Study

Background

Cognitive decline is a major reason for dependence and resource use in long-term care.

Objective

We explored whether social activities may prevent cognitive decline of older residents of long-term care facilities.

Methods

In a routine care cohort, 3,603 residents of long-term care facilities were assessed on average 4.4 times using the interRAI-Long-Term-Care-Facilities instrument which includes frequency of participation in social activities of long standing interest over the last 30 days and the Cognitive Performance Scale. Linear mixed models repeated measures analyses were performed corrected for age, sex, physical activity, Activities of Daily Living, mood, and health indicators.

Results

Social activity was associated with cognitive preservation over time. This association was stronger in those with no or mild cognitive impairment at baseline, relative to those with moderate to severe impairment. Participation in specific social activities such as conversing and helping others showed a similar positive association. The relation between social activity and cognitive impairment appeared to be bi-directional.

Conclusions

The protective effects of social activity offer a window of opportunity to preserve cognitive functioning in long-term care residents.

The association between loneliness or social isolation and food and eating behaviours: A scoping review

Loneliness or social isolation and food/eating behaviours have important health consequences and there are rationales for why they could interact. Loneliness and dietary behaviours are recognised as health determinants and targets for interventions at individual, group and population levels. However, there are currently no research reviews investigating associations between these areas. This scoping review synthesized evidence investigating loneliness or social isolation and food/eating behaviours in people aged over 16 years in high-income countries. A systematic search of five databases from 2000 was conducted using predetermined search terms. Dissertation database and backwards citation searches were also conducted. Full text screening of 254 articles/theses resulted in inclusion of three qualitative and 26 quantitative studies, with eight conducted in COVID-19 lockdowns. Almost all studies reported a relationship between loneliness/social isolation and eating behaviours usually considered harmful such as low fruit and vegetable intake and lower diet quality. Qualitative research also supports the detrimental influence of loneliness or social isolation on eating. Study quality was considered, and interpretation and comparison of results was complicated by use of varying methods. Better awareness and understanding of the relationship between these complex aspects of health is needed to inform the development of interventions and practice of nutrition and mental health practitioners, policymakers, researchers and end-users.

Multicenter observational survey on psychosocial and behavioral impacts of COVID-19 in people living with HIV in Northern Vietnam

Socially marginalized groups, including people living with HIV/AIDS (PLHIV), could be disproportionately affected by Coronavirus disease 2019 (COVID-19). Following an initial single-center survey conducted in 2020, we conducted a second survey of 11 antiretroviral therapy (ART) sites in Northern Vietnam between June 2021 and January 2022. We tested anti-SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) nucleocapsid IgG antibodies and assessed prevention against COVID-19 and impacts of COVID-19 on access to ART, economic security, risky health behaviors, and mental health using self-reported questionnaires. In total, 7808 PLHIV on ART participated in the second survey. The overall prevalence of SARS-CoV-2 antibody was as low as 1.2%. There was no clear upward trend in COVID-19 infection among PLHIV compared with the rate of infection among the general population. HIV treatment was generally maintained and no increase in risky health behaviors was observed. The economic impacts were significant, with high unemployment rate, poorer economic security, and binge drinking strongly associated with depression. However, the prevalence of depression decreased by 11.2% compared with pre-COVID-19 levels. Social support, including for patients to continue HIV treatment and effective employment/financial assistance, may help to alleviate the negative socioeconomic impacts of COVID-19 and improve mental health among PLHIV.

Cognitive decline in older adults in the UK during and after the COVID-19 pandemic: a longitudinal analysis of PROTECT study data

BACKGROUND

Although the long-term health effects of COVID-19 are increasingly recognised, the societal restrictions during the COVID-19 pandemic hold the potential for considerable detriment to cognitive and mental health, particularly because major dementia risk factors-such as those related to exercise and dietary habits-were affected during this period. We used longitudinal data from the PROTECT study to evaluate the effect of the pandemic on cognition in older adults in the UK.

METHODS

For this longitudinal analysis, we used computerised neuropsychology data from individuals aged 50 years and older participating in the PROTECT study in the UK. Data were collected from the same participants before the COVID-19 pandemic (March 1, 2019-Feb 29, 2020) and during its first (March 1, 2020-Feb 28, 2021) and second (March 1, 2021-Feb 28, 2022) years. We compared cognition across the three time periods using a linear mixed-effects model. Subgroup analyses were conducted in people with mild cognitive impairment and in people who reported a history of COVID-19, and an exploratory regression analysis identified factors associated with changes in cognitive trajectory.

FINDINGS

Pre-pandemic data were included for 3142 participants, of whom 1696 (54·0%) were women and 1446 (46·0%) were men, with a mean age of 67·5 years (SD 9·6, range 50-96). Significant worsening of executive function and working memory was observed in the first year of the pandemic across the whole cohort (effect size 0·15 [95% CI 0·12-0·17] for executive function and 0·51 [0·49-0·53] for working memory), in people with mild cognitive impairment (0·13 [0·07-0·20] and 0·40 [0·36-0·47]), and in people with a history of COVID-19 (0·24 [0·16-0·31] and 0·46 [0·39-0·53]). Worsening of working memory was sustained across the whole cohort in the second year of the pandemic (0·47; 0·44-0·49). Regression analysis indicated that cognitive decline was significantly associated with reduced exercise (p=0·0049; executive function) and increased alcohol use (p=0·049; working memory) across the whole cohort, as well as depression (p=0·011; working memory) in those with a history of COVID-19 and loneliness (p=0·0038; working memory) in those with mild cognitive impairment. In the second year of the pandemic, reduced exercise continued to affect executive function across the whole cohort, and associations were sustained between worsening working memory and increased alcohol use (p=0·0040), loneliness (p=0·042), and depression (p=0·014) in those with mild cognitive impairment, and reduced exercise (p=0·0029), loneliness (p=0·031) and depression (p=0·036) in those with a history of COVID-19.

INTERPRETATION

The COVID-19 pandemic resulted in a significant worsening of cognition in older adults, associated with changes in known dementia risk factors. The sustained decline in cognition highlights the need for public health interventions to mitigate the risk of dementia-particularly in people with mild cognitive impairment, in whom conversion to dementia within 5 years is a substantial risk. Long-term intervention for people with a history of COVID-19 should be considered to support cognitive health.

Assessment of COVID-19 lockdown effect on early Alzheimer Disease progression

INTRODUCTION

Recently, many aspects of daily life have changed due to the COVID-19 pandemic. Patients with Alzheimer Disease (AD) could be more vulnerable to those daily life changes as experts expected. Mainly, the lockdown involved reduced social contact and cognitive stimulation. So, it could affect the AD expression, increasing the patients' disabilities development.

OBJECTIVE

The aim of this study is to evaluate the effect of COVID-19 lockdown on cognitive impairment progression in early AD patients.

METHODOLOGY

The participants were patients with mild cognitive impairment due to AD (MCI-AD) from the Neurology Unit (La Fe Hospital), who were neuropsychologically evaluated (cognitive impairment, daily activity tests) twice over 2 years. They were classified into a case group (n = 21), evaluated before and after lockdown condition, and a control group (n = 20), evaluated entirely before the lockdown condition.

RESULTS

All the participants showed increasing cognitive impairment and functional deterioration over the 2-year period of evaluation (p < 0.05). However, a faster worsening was not observed as a consequence of the COVID-19 pandemic and the lockdown condition. In fact, the statistical significance observed between the two study groups for daily life activities showed that the worsening was even lesser in the group evaluated under the lockdown condition.

CONCLUSION

Medium-term effects of COVID-19 lockdown could not involve an acceleration of the cognitive decline in MCI-AD patients in a 2-year evaluation period. In addition, the least worsening observed for daily living activities in the case group was probably due to the change in routines. Therefore, the common assumption of cognitive worsening of AD progression due to the lockdown in comparison with normal disease progression was not demonstrated in this study, at least for MCI-AD cases. However, more longitudinal studies are required to evaluate long-term effects in these patients.

Social interaction trajectories and all-cause mortality in older adults: the Otassha study

Introduction

This longitudinal study aimed to identify aging trajectory patterns of social interaction by sex and determine the association between these patterns and all-cause mortality.

Methods

Participants were 4,065 community-dwelling older adults (1849 men) in Japan, aged 65-89 years, who responded twice or more to a mail survey conducted between 2012 and 2020. Social interaction was examined through the frequency of face-to-face and non-face-to-face contact with non-resident family and friends. The aging trajectories of the social interaction scores were identified using group-based trajectory modeling.

Results

Two groups were identified among both men and women. Among men with high-frequency interaction, a rapid decrease in the frequency of social interaction was observed after 80 years of age. Conversely, among women, the frequency tended to remain the same, even after 80 years of age. The social interaction score among those aged 65 years in the low-frequency group was approximately 4 points for men and 6 points for women. Among men, no decrease was observed; however, it tended to decline after 85 years of age among women. Among men, the factors associated with the low-frequency group were instrumental activities of daily living score, perceived financial status, and social participation, while among women, they were self-rated health and social participation. The adjusted hazard ratio in the low-frequency group for all-cause mortality was 1.72 (95% confidence interval, 1.27-1.72) for men and 1.45 (95% confidence interval, 0.98-2.14) for women.

Discussion

In the low-frequency group, men had a higher risk of all-cause mortality than women. Daily social interaction from mid-age is important to reduce the risk of social isolation and all-cause mortality in later life.

The Impact of Loneliness and Social Isolation on Cognitive Aging: A Narrative Review

Social concepts such as loneliness and social isolation are fairly new factors that have been recently gaining attention as to their involvement in changes in cognitive function and association with dementia. The primary aim of this narrative review was to describe the current understanding of how loneliness and social isolation influence cognitive aging and how they are linked to dementia. Studies have shown that there is an association between loneliness, social isolation, and reduced cognitive function, in older adults, across multiple cognitive domains, as well as a heightened risk of dementia. Numerous changes to underlying neural biomechanisms including cortisol secretion and brain volume alterations (e.g., white/grey matter, hippocampus) may contribute to these relationships. However, due to poor quality research, mixed and inconclusive findings, and issues accurately defining and measuring loneliness and social isolation, more consistent high-quality interventions are needed to determine whether studies addressing loneliness and social isolation can impact longer term risk of dementia. This is especially important given the long-term impact of the COVID-19 pandemic on social isolation in older people is yet to be fully understood.

Predictors of loneliness onset and maintenance in European older adults during the COVID-19 pandemic

Objectives

Loneliness is a major public health concern. Duration of loneliness is associated with severity of health outcomes, and further research is needed to direct interventions and social policy. This study aimed to identify predictors of the onset vs. the maintenance of loneliness in older adults before and during the pandemic using longitudinal data from the Survey of Health, Age, and Retirement in Europe (SHARE).

Methods

Groupings of persistent, situational, and no loneliness were based on self-reports from an ordinary pre-pandemic SHARE wave and a peri-pandemic telephone interview. Predictors were identified and compared in three hierarchical binary regression analyses, with independent variables added in blocks of geographic region, demographics, pre-pandemic social network, pre-pandemic health, pandemic-related individual, and country level variables.

Results

Self-reported loneliness levels for the persistent, situational, and no loneliness groups were stable and distinct through 7 years preceding the pre-pandemic baseline measure. Shared predictors were chronic diseases, female sex, depression, and no cohabitant partner. Persistent loneliness was uniquely predicted by low network satisfaction (OR: 2.04), functional limitations (OR: 1.40), and a longer country-level isolation period for older adults (OR: 1.24).

Conclusion

Interventions may target persons with depression, functional limitations, chronic health issues, and no cohabitant partner. The added burden of the length of isolation on those who are already lonely should be taken into account when employing social policies that target older adults. Further research should distinguish between situational and persistent loneliness, and seek to identify predictors of chronic loneliness onset.

Happy Alone? Motivational Profiles of Solitude and Well-Being Among Senior Living Residents

Research on solitude in older adulthood is scarce, and findings are mixed on whether time alone at this age is risky or beneficial. A mixed-method study was conducted to examine patterns of motivations for solitude among senior living residents (N = 397, Mage = 83) and associations with well-being. Cluster analyses identified four motivational profiles: Low, Positive, Negative, and Dual. Overall, those with Low and Positive motivations for solitude displayed greater levels of well-being on both hedonic (e.g., life satisfaction) and eudaimonic (e.g., personal growth) measures; in particular, the Positive profile showed significantly higher levels of psychological richness. Themes drawn from responses to open-ended survey questions asking about the benefits and challenges of both socializing and being alone are discussed in light of the four motivational profiles, and implications for aging services are discussed.

Is there a correlation between sensory impairments and social isolation in middle-aged and older Chinese population? Cross-sectional and longitudinal evidence from a nationally representative survey

Purpose

The aim of this study is to investigate the cross-sectional and longitudinal associations between sensory impairments (SIs) including single vision impairment (SVI), single hearing impairment (SHI), and dual sensory impairments (DSI) with social isolation in the middle-aged and older Chinese population.

Methods

Data were obtained from the China Health and Retirement Longitudinal Survey (CHARLS). In total, 11,674 Chinese older adults aged over 45 were included at baseline 2011, and 6,859 participants who accomplished all four interviews from 2011 to 2018 were adapted for longitudinal analyses. Sensory status and social isolation measurements including social disconnectedness and self-perceived loneliness were collected. Assessment of social disconnectedness included the number of types of social activities in which they participated and the frequency of such participation. Loneliness referred to the subjective perception of loneliness. Other covariates included socio-demographic characteristics, medical conditions, and lifestyle-related factors. The impacts of baseline sensory status on social disconnectedness and loneliness were assessed using univariate and multivariate generalized linear models. A generalized linear model with generalized estimation equations (GEE) was used to assess the association between time-varying sensory statuses with social disconnectedness or loneliness over 8 years after being adjusted with multi-confounding factors.

Results

Participants with SIs had significantly higher levels of social disconnectedness and self-perceived loneliness, compared to those who were free of SI. All kinds of SIs were significantly associated with loneliness according to both cross-sectional and longitudinal data. The correlations between DSI and social disconnectedness or loneliness at baseline and over 8 years were also noticed. SHI was found to be significantly associated with both frequency and types of social activities according to cross-sectional data and with the frequency of social activity participation in longitudinal analysis. SVI was only associated with the types of social activities at baseline (all p-values &lt; 0.05).

Conclusion

Sensory impairments, especially dual sensory impairments, have explicitly detrimental effects on social isolation among the older Chinese population. Over time, single hearing impairment specifically jeopardizes their frequency rather than types of social activities participation.

Joys or Sorrows of Parenting During the COVID-19 Lockdown: A Scoping Review

Objectives: The aim of this scoping review was to map out the existing evidence of the impact of the COVID-19 lockdown on parents of children and adolescents. We sought to: 1) identify parenting domains that were particularly affected by lockdown measures, 2) describe the challenges and opportunities of lockdown measures in these domains, and 3) define protective and exacerbating factors modulating the effect of lockdown measures on parents. Methods: We identified five main domains investigated in the context of parenting during the early COVID-19 lockdown derived from 84 studies: health and wellbeing, parental role, couple functioning, family and social relationships, and paid and unpaid work. For each domain, we listed challenges and opportunities, as well as discriminant factors. Results: The lockdown impacted all five different but interconnected domains, introduced new roles in parents' lives, and particularly affected women and vulnerable populations. Conclusion: This scoping review highlights the importance of approaching public health policymaking from a social justice perspective. Such an approach argues for social and public health policies to promote health accounting for its social, economic, political, and commercial determinants.

Nurses' perception towards care robots and their work experience with socially assistive technology during COVID-19: A qualitative study

This study aimed to explore nurses' perceptions towards care robots and their work experiences in caring for older adults who use socially assistive technology. This qualitative descriptive study included 18 nurses who cared for older adults with dementia or living alone at home. Interviews via Zoom were conducted, and the collected data were analyzed using inductive content analysis. The three themes were identified: (1) perceived benefits, (2) perceived challenges, and (3) improvements needed to enhance the quality of care. The participants perceived that the care robot and socially assistive technology were useful in caring for older adults during COVID-19. However, they noted that the limited capabilities of the technology and an increased workload negatively impacted the quality of care for older adults. The findings of this study indicated that socially assistive technology and care robots have potential benefits in assisting older adults with dementia or living alone.

Individual differences among older adults with mild and moderate dementia in social and emotional loneliness and their associations with cognitive and psychological functioning

Background

Loneliness is a major health issue among older adults. The aim of this study was to assess the relationship between loneliness, in its social and emotional facets, and the cognitive (language), and behavioral/psychological functioning as well as quality of life (QoL) in people with mild and moderate dementia, i.e., considering dementia severity as an individual characteristic.

Methods

This cross-sectional study involved 58 people with mild dementia and 55 people with moderate dementia. Participants completed the Social and Emotional Loneliness scale, along with measures assessing their language skills, the frequency and severity of their behavioral and psychological symptoms, and their QoL.

Results

Socio-demographic characteristics and depression, but not loneliness or its social and emotional facets, contributed to explain participants’ behavioral and psychological symptoms, regardless of dementia severity. Loneliness explained, though to a small extent (8% of variance), language skills in people with moderate dementia, with social loneliness only accounting for language skills (18% of variance) in this group. Loneliness also modestly accounted for dysphoria symptoms in both the mildly and moderately impaired (6% and 5% of variance, respectively) individuals with social loneliness predicting dysphoric mood in the former group only (7% of variance). Loneliness also explained, to a larger extent, QoL in both the mildly impaired and moderately impaired individuals (27% and 20% of variance, respectively), its social facet predicting QoL in the mildly impaired (30% of variance), and its emotional facet in the moderately impaired (21% of variance) group.

Conclusion

These findings suggest that loneliness and its facets have a clear impact on perceived QoL, and influence the language skills and dysphoria symptoms of people with dementia, to a degree that depends on dementia severity. The assessment of loneliness and its facets in people with dementia considering dementia severity, and the promotion of social inclusion to reduce it should be considered by professionals.

Who is essential in care? Reflections from the pandemic's backstage

Since the beginning of the pandemic spread of the Coronavirus, societies have been reminded that the impact of Covid-19 and public health measures of infection containment reflect known gradients of inequality. Measures focusing only the (acknowledged) frontstage of the pandemic and neglecting its (unacknowledged) backstage—understood as those framework conditions indispensable for societies to thrive—have worsened the impact of social determinants of health on the most vulnerable, as shown by the deleterious effects of prolonged social isolation of residents of nursing homes. To reflect this phenomenon ethically, a framework is proposed which is inspired by the feminist philosopher Margret Little. At its core stands the assumption that caring for people and moral ends allows us to identify what is morally salient. This epistemological stance allows a critical look at the alleged dilemmas invoked to enforce brute, long-lasting policies of closing nursing homes in many places—especially in the light of their dubious effectiveness in preventing viral spread and the severe physical and psychological consequences for those affected. If moral salience is only fully perceived through the closeness of the caring relationship, the human suffering resulting from these policies reveals the utter inadequacy of the dilemma rhetoric used to justify them. This insight is illustrated by the personal experience of the author: He describes his role as an essential care partner of his mother living in a nursing home and forced into the role of a “visitor” who witnessed a constant deterioration of care. Based on an epistemological understanding of caring for making reliable moral judgments, potentially exclusionary effects of distinguishing essential from non-essential groups in care will be addressed together with the need to overcome strict boundaries between front- and backstage. Such efforts will strengthen the moral community of persons needing care, professional care givers and essential care partners.

The Impact of Social Isolation Due to COVID-19 on Symptom Progression in People With Dementia: Findings of the SOLITUDE Study

BACKGROUND

People with dementia (PWD) are vulnerable to abrupt changes to daily routines. The lockdown enforced on the 23rd of March 2020 in the UK to contain the expansion of the COVID-19 pandemic limited opportunities for PWD to access healthcare services and socialise. The SOLITUDE study explored the potential long-term effects of lockdown on PWD's symptoms and carers' burden.

METHODS

Forty-five carers and 36 PWD completed a telephone-based assessment at recruitment (T0) and after 3 (T1) and 6 months (T2). PWD completed measures validated for telephonic evaluations of cognition and depression. Carers completed questionnaires on their burden and on PWD's health and answered a customised interview on symptom changes observed in the initial months of lockdown. Longitudinal changes were investigated for all outcome variables with repeated-measures models. Additional post hoc multiple regression analyses were carried out to investigate whether several objective factors (i.e., demographics and time under social restrictions) and carer-reported symptom changes observed following lockdown before T0 were associated with all outcomes at T0.

RESULTS

No significant changes were observed in any outcomes over the 6 months of observations. However, post hoc analyses showed that the length of social isolation before T0 was negatively correlated with episodic and semantic memory performance at T0. Carers reporting worsening of neuropsychiatric symptoms and faster disease progression in PWD also reported higher burden. Moreover, carer-reported worsening of cognitive symptoms was associated with poorer semantic memory at T0.

CONCLUSION

PWD's symptoms and carers' burden remained stable over 6 months of observation. However, the amount of time spent under social restrictions before T0 appears to have had a significant detrimental impact on cognitive performance of patients. In fact, carer-reported cognitive decline during social isolation was consistent with the finding of poorer semantic memory, a domain sensitive to progression in Alzheimer's disease. Therefore, the initial stricter period of social isolation had greater detrimental impact on patients and their carers, followed then by a plateau. Future interventions may be designed to maintain an optimal level of social and cognitive engagement for PWD in challenging times, to prevent abrupt worsening of symptoms and associated detrimental consequences on patients' carers.
