RESUMO
OBJECTIVE: To identify barriers and facilitators to the use of formal dementia services among underserved and minority groups (UMG) in the United States and Germany. METHOD: Semi-structured qualitative interviews with caregivers (N = 18) of persons with dementia in the United States and Germany. Data were analyzed using thematic analysis. RESULTS: Caregivers described their experiences in three stages of seeking, initiating, and utilizing care, and different factors served to hinder or enable the use of care services in each stage. The most important factors included limited knowledge about dementia, challenges interacting with healthcare systems, and how closely formal services met the expectations and needs of caregivers, particularly with regard to accommodating cultural or ethnic/racial identity. Caregivers preferred interacting with service care providers who shared a similar identity to receive information or services. CONCLUSION: Barriers and facilitators to using dementia care services vary by stage of engaging services and may be shared across different healthcare contexts. Targeting specific barriers and strengthening facilitators could help reduce disparities in dementia care among UMG.

OBJECTIVE: Higher levels of loneliness in older adulthood predict cognitive decline, but research on mediating mechanisms is sparse. We examine multisystemic physiological risk, functional ability, self-rated health, depressive symptoms, and social participation as mediating processes for the association between loneliness and general cognitive ability over a 10-year follow-up in an older adult sample. METHODS: Three waves of data from 3,005 individuals (mean intake age: 69.30 (SD: 7.85) years; femaleâ¯=â¯51.61%) recruited during Wave 1 of the National Social Life, Health, and Aging Project were used to test whether hypothesized mediators collected at the 5-year follow-up explained effects of baseline loneliness on 10-year general cognitive ability. RESULTS: The relationship between baseline loneliness and 10-year general cognitive ability was not mediated by multisystemic physiological risk. Functional ability (bâ¯=â¯-0.24, SEâ¯=â¯0.05, p <0.001), self-rated health (b = -0.08, SEâ¯=â¯0.02, p <0.001), depressive symptoms (b= -0.20, SEâ¯=â¯0.05, p <0.001), and social participation (bâ¯=â¯-0.03, SEâ¯=â¯0.01, pâ¯=â¯0.016) significantly mediated effects. Indirect effects remained significant after adjusting for demographic covariates and 5-year general cognitive ability, except social participation. DISCUSSION: Loneliness may influence cognitive ability indirectly, signaling waning physical and psychiatric health more proximally correlated with cognitive ability. These mechanisms may serve as targets of intervention for cognitive maintenance in lonely older adults.

Latent variable models can create a latent dementia index (LDI) using cognitive and functional ability to approximate dementia likelihood. The LDI approach has been applied across diverse cohorts. It is unclear whether sex affects its measurement properties. We use Wave A (2001-2003) of the Aging, Demographics, and Memory Study (n = 856). Multiple group confirmatory factor analysis (CFA) was used to test measurement invariance (MI) using informant-reported functional ability and cognitive performance tasks, which we group into verbal, nonverbal, and memory. Partial scalar invariance was found, allowing for testing sex differences in LDI means (MDiff = 0.38). The LDI correlated with consensus panel dementia diagnosis, Mini-Mental State Examination (MMSE), and dementia risk factors (low education, advanced age, and apolipoprotein ε4 [APOE-ε4] status) for men and women. The LDI validly captures dementia likelihood to permit estimation of sex differences. LDI sex differences indicate higher dementia likelihood in women, potentially due to social, environmental, and biological factors.
RESUMO
BACKGROUND: Family caregivers of people living with dementia benefit from supportive service use to address care needs associated with caregiving. Yet, research consistently demonstrates low rates of service use. Existing research has focused on barriers and facilitators to service use, with few studies examining the influence of caregivers' environmental context which often patterns social advantage and health services accessibility. OBJECTIVE: To describe the perspectives of caregivers residing in socially disadvantaged areas have in regards to utilizing supportive services. METHODS: Ten informal caregivers residing in socially disadvantaged areas participated in in-depth interviews that were analyzed using thematic analysis. RESULTS: Across all interviews, caregivers spontaneously described common precedents of service use (crisis or accumulation of unmet needs) and a distinct sequence of stages (seeking, initiating, and utilizing) surrounding service engagement. Major themes characterizing caregivers' experiences throughout service engagement highlight the varied influence of personal, familial, health, and social system-related factors. Findings demonstrate that caregivers may have different service needs as dementia progresses and that gerontological social work practice can facilitate service use. CONCLUSION: While preliminary, these findings provide important insights into new domains that can be further examined in future research and intervention efforts to improve supportive service use in socially disadvantaged and underserved communities.

Although several studies have shown small longitudinal associations between baseline loneliness and subsequent dementia risk, studies rarely test whether change in loneliness predicts dementia risk. Furthermore, as both increase with advancing age, genetic and environmental selection processes may confound the putative causal association between loneliness and dementia risk. We used a sample of 2,476 individual twins from three longitudinal twin studies of aging in the Swedish Twin Registry to test the hypothesis that greater positive change in loneliness predicts greater dementia risk. We then used a sample of 1,632 pairs of twins to evaluate the hypothesis that effects of change in loneliness on dementia risk would remain after adjusting for effects of genetic and environmental variance. Phenotypic model results suggest that mild levels of baseline loneliness predict greater dementia risk. Contrary to our hypothesis, change in loneliness did not correlate with dementia risk, regardless of whether genetic and environmental selection confounds were taken into account. Worsening loneliness with age may not confer greater dementia risk.
RESUMO
As the spread of COVID-19 has led to global efforts to social distance, concerns about the negative psychological effects of social isolation and loneliness have grown. The purpose of this commentary is to draw attention to 2 populations across the life span at risk for the psychological sequelae of social isolation and loneliness: young adults and old-old adults. We present data from three population-based longitudinal studies from two nations (United States and Sweden) to support this view. We then provide recommendations for the prevention of loneliness during social distancing as well as after social distancing measures are eased through implementation of programs that match young adults with older adults to foster intergenerational connection and group-based psychotherapy.

BACKGROUND: As the proportion of older people with migration background (PwM) increases, the proportion of older PwM with dementia might also increase. Dementia is underdiagnosed in this group and a large proportion of PwM with dementia and family caregivers are not properly supported. Healthcare utilization is lower among older migrant populations. Thus, a better understanding of how PwM and family caregivers perceive their situation and how they experience healthcare services is needed to improve utilization of the healthcare system. OBJECTIVE: Analyze how family caregivers of PwM with dementia experience their situation, why healthcare services are utilized less often, and what can be done to reverse this. METHODS: Eight semi-structured interviews were conducted with people with Turkish migration background caring for PwM with dementia. Qualitative content analysis was used for data analysis. RESULTS: Daily care was performed by one family member with the support of others. Healthcare services were used by most participants. Participants identified a need for better access to relevant information and incorporation of Turkish culture into healthcare services. CONCLUSION: PwM face similar challenges in taking care of persons with dementia as those without migration background. There is a willingness to use services, and services embracing Turkish culture would help to reduce hesitance and make affected people feel more comfortable, thereby increasing utilization and satisfaction. A limitation of this study is that participants were already connected to health services, which may not reflect the help-seeking behavior of those in the Turkish community who are not involved in healthcare.

INTRODUCTION: Residence in a disadvantaged neighborhood associates with adverse health exposures and outcomes, and may increase risk for cognitive impairment and dementia. Utilization of a publicly available, geocoded disadvantage metric could facilitate efficient integration of social determinants of health into models of cognitive aging. METHODS: Using the validated Area Deprivation Index and two cognitive aging cohorts, we quantified Census block-level poverty, education, housing, and employment characteristics for the neighborhoods of 2119 older adults. We assessed relationships between neighborhood disadvantage and cognitive performance in domains sensitive to age-related change. RESULTS: Participants in the most disadvantaged neighborhoods (n = 156) were younger, more often female, and less often college-educated or white than those in less disadvantaged neighborhoods (n = 1963). Disadvantaged neighborhood residence associated with poorer performance on tests of executive function, verbal learning, and memory. DISCUSSION: This geospatial metric of neighborhood disadvantage may be valuable for exploring socially rooted risk mechanisms, and prioritizing high-risk communities for research recruitment and intervention.
RESUMO
Importance: Identifying risk factors for brain atrophy during the aging process can help direct new preventive approaches for dementia and cognitive decline. The association of neighborhood socioeconomic disadvantage with brain volume in this context is not well known. Objective: To test whether neighborhood-level socioeconomic disadvantage is associated with decreased brain volume in a cognitively unimpaired population enriched for Alzheimer disease risk. Design, Setting, and Participants: This study, conducted from January 6, 2010, to January 17, 2019, at an academic research neuroimaging center, used cross-sectional data on 951 participants from 2 large, ongoing cohort studies of Alzheimer disease (Wisconsin Registry for Alzheimer's Prevention and Wisconsin Alzheimer's Disease Research Center clinical cohort). Participants were cognitively unimpaired based on National Institute on Aging-Alzheimer's Association workgroup diagnostic criteria for mild cognitive impairment and Alzheimer disease, confirmed through a consensus diagnosis panel. The cohort was enriched for Alzheimer disease risk based on family history of dementia. Statistical analysis was performed from April 3 to September 27, 2019. Main Outcomes and Measures: The Area Deprivation Index, a geospatially determined index of neighborhood-level disadvantage, and cardiovascular disease risk indices were calculated for each participant. Linear regression models were fitted to test associations between relative neighborhood-level disadvantage (highest 20% based on state of residence) and hippocampal and total brain tissue volume, as assessed by magnetic resonance imaging. Results: In the primary analysis of 951 participants (637 women [67.0%]; mean [SD] age, 63.9 [8.1] years), living in the 20% most disadvantaged neighborhoods was associated with 4.1% lower hippocampal volume (ß = -317.44; 95% CI, -543.32 to -91.56; P = .006) and 2.0% lower total brain tissue volume (ß = -20â¯959.67; 95% CI, -37â¯611.92 to -4307.43; P = .01), after controlling for intracranial volume, individual-level educational attainment, age, and sex. Robust propensity score-matched analyses determined that this association was not due to racial/ethnic or demographic characteristics. Cardiovascular risk score, examined in a subsample of 893 participants, mediated this association for total brain tissue but not for hippocampal volume. Conclusions and Relevance: For cognitively unimpaired individuals, living in the most disadvantaged neighborhoods was associated with significantly lower cerebral volumes, after controlling for maximal premorbid (total intracranial) volume. This finding suggests an association of community socioeconomic context, distinct from individual-level socioeconomic status, with brain volume during aging. Cardiovascular risk mediated this association for total brain tissue volume but not for hippocampal volume, suggesting that neighborhood-level disadvantage may be associated with these 2 outcomes via distinct biological pathways.
