Abstract
Black and Latinx Americans are disproportionately at greater risk for having Alzheimer's disease and related dementias (ADRD) than White Americans. Such differences in risk for ADRD are arguably explained through health disparities, social inequities, and historical policies. Structural racism and discrimination (SRD), defined as "macro-level conditions that limit opportunities, resources, and well-being of less privileged groups," have been linked with common comorbidities of ADRD, including hypertension, obesity, diabetes, depression. Given the historical impact of SRD-including discriminatory housing policies resulting in racial residential segregation that has been shown to limit access to education, employment, and healthcare-Black and Latinx populations with ADRD are directly or indirectly negatively affected by SRD in terms of access, quality and cost for healthcare. Emerging studies have brought to light the value of structural-level hospital and public health collaboration on care coordination for improving healthcare quality and access, and thus could serve as a macro-level mechanism for addressing disparities for minoritized racial and ethnic populations with ADRD. This paper presents a conceptual framework delineating how care coordination can successfully be achieved through health information technology (HIT) systems and ultimately address SRD. To address health inequities, it is therefore critical that policy initiatives invest in HIT capacities and infrastructures to promote care coordination, identify patient needs and preferences, and promote engagement of patients with ADRD and their caregivers.

Abstract
OBJECTIVES Caregivers of individuals with Alzheimer's disease and related dementias experience significant burden and adverse outcomes. Enhancing caregiver self-efficacy has the potential to mitigate these negative impacts, yet little is known about its relationship with other aspects of caregiving. This study examined the relationship between self-efficacy and outcomes; identified factors associated with self-efficacy; examined the mediating role of self-efficacy; and analyzed whether there were racial/ethnic differences. METHODS Data from caregivers (N = 243) were collected from the Caring for the Caregiver Network study. Participants' level of self-efficacy, depression, burden, and positive aspects of caregiving was assessed using validated measures. RESULTS Two self-efficacy subscales predicted caregiver depression, burden, and positive aspects of caregiving. Being White, a spouse, or having a larger social network predicted lower self-efficacy for obtaining respite. Higher income and lower preparedness predicted lower self-efficacy for controlling upsetting thoughts and responding to disruptive behaviors. Self-efficacy for controlling upsetting thoughts mediated the relationship between preparedness and depression along with the relationship between preparedness and burden. Race/ethnicity did not improve model fit. CONCLUSION Self-efficacy plays an important role in caregiver outcomes. These findings indicate that strategies to improve caregiver self-efficacy should be an integral component of caregiver interventions.

Global and regional projections of the economic burden of Alzheimer's disease and related dementias from 2019 to 2050: A value of statistical life approach. EClinicalMedicine 2022; 51:101580. [PMID: 35898316 PMCID: PMC9310134 DOI: 10.1016/j.eclinm.2022.101580] [Citation(s) in RCA: 55] [Impact Index Per Article: 27.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/06/2022] [Revised: 07/06/2022] [Accepted: 07/07/2022] [Indexed: 10/25/2022] Open
Abstract
BACKGROUND The burden of Alzheimer's disease and related dementias (ADRDs) is expected to grow rapidly with population aging, especially in low- and middle-income countries, in the next few decades. We used a willingness-to-pay approach to project the global, regional, and national economic burden of ADRDs from 2019 to 2050 under status quo. METHODS We projected age group and country-specific disability-adjusted life years (DALYs) lost to ADRDs in future years based on historical growth in disease burden and available population projections. We used country-specific extrapolations of the value of a statistical life (VSL) year and its future projections based on historical income growth to estimate the economic burden - measured in terms of the value of lost DALYs - of ADRDs. A probabilistic uncertainty analysis was used to calculate point estimates and 95% uncertainty bounds of the economic burden. FINDINGS In 2019, the global VSL-based economic burden of ADRDs was an estimated $2.8 trillion. The burden was projected to increase to $4.7 trillion (95% uncertainty bound: $4 trillion-$5.5 trillion) in 2030, $8.5 trillion ($6.8 trillion-$10.8 trillion) in 2040, and $16.9 trillion ($11.3 trillion-$27.3 trillion) in 2050. Low- and middle-income countries (LMICs) would account for 65% of the global VSL-based economic burden in 2050, as compared with only 18% in 2019. Within LMICs, upper-middle income countries would carry the largest VSL-based economic burden by 2050 (92% of LMICs burden and 60% of global burden). INTERPRETATION ADRDs have a large and inequitable projected future VSL-based economic burden. FUNDING The Davos Alzheimer's Collaborative.

Abstract
The health, well-being, and financial security of Americans are greatly impacted by Alzheimer's disease. The forecast paints an upward trajectory with the number of Americans suffering from Alzheimer's disease and related dementia. To discuss the Alzheimer's crisis, The Senate Committee on Finance, Subcommittee on Health Care, held a hearing titled, "The Alzheimer's Crisis: Examining, Testing, and Treatment Pipelines and Fiscal Implications," on December 16, 2020. Here, we summarize and expand on the discussion of the panel and its review of recent progress, ongoing challenges associated with Alzheimer's disease, and potential initiatives that promise to speed progress in developing treatments and improving care.

Abstract
Limbic-predominant age-related TDP-43 encephalopathy neuropathologic change (LATE-NC) and Alzheimer's disease neuropathologic change (ADNC) are each associated with substantial cognitive impairment in aging populations. However, the prevalence of LATE-NC across the full range of ADNC remains uncertain. To address this knowledge gap, neuropathologic, genetic, and clinical data were compiled from 13 high-quality community- and population-based longitudinal studies. Participants were recruited from United States (8 cohorts, including one focusing on Japanese-American men), United Kingdom (2 cohorts), Brazil, Austria, and Finland. The total number of participants included was 6196, and the average age of death was 88.1 years. Not all data were available on each individual and there were differences between the cohorts in study designs and the amount of missing data. Among those with known cognitive status before death (n = 5665), 43.0% were cognitively normal, 14.9% had MCI, and 42.4% had dementia-broadly consistent with epidemiologic data in this age group. Approximately 99% of participants (n = 6125) had available CERAD neuritic amyloid plaque score data. In this subsample, 39.4% had autopsy-confirmed LATE-NC of any stage. Among brains with "frequent" neuritic amyloid plaques, 54.9% had comorbid LATE-NC, whereas in brains with no detected neuritic amyloid plaques, 27.0% had LATE-NC. Data on LATE-NC stages were available for 3803 participants, of which 25% had LATE-NC stage > 1 (associated with cognitive impairment). In the subset of individuals with Thal Aβ phase = 0 (lacking detectable Aβ plaques), the brains with LATE-NC had relatively more severe primary age-related tauopathy (PART). A total of 3267 participants had available clinical data relevant to frontotemporal dementia (FTD), and none were given the clinical diagnosis of definite FTD nor the pathological diagnosis of frontotemporal lobar degeneration with TDP-43 inclusions (FTLD-TDP). In the 10 cohorts with detailed neurocognitive assessments proximal to death, cognition tended to be worse with LATE-NC across the full spectrum of ADNC severity. This study provided a credible estimate of the current prevalence of LATE-NC in advanced age. LATE-NC was seen in almost 40% of participants and often, but not always, coexisted with Alzheimer's disease neuropathology.

Abstract
INTRODUCTION As the population ages, Alzheimer's disease and related dementias (ADRD) are becoming increasingly common in patients presenting to the emergency department (ED). This study compares the frequency of ED use among a cohort of individuals with well-defined cognitive performance (cognitively intact, mild cognitive impairment (MCI), and ADRD). METHODS We performed a retrospective cohort study of English-speaking, community-dwelling individuals evaluated at four health system-based multidisciplinary memory clinics from 2014-2016. We obtained demographic and clinical data, including neuropsychological testing results, through chart review and linkage to electronic health record data. We characterized the frequency and quantity of ED use within one year (6 months before and after) of cognitive evaluation and compared ED use between the three groups using bivariate and multivariate approaches. RESULTS Of the 779 eligible patients, 89 were diagnosed as cognitively intact, 372 as MCI, and 318 as ADRD. The proportion of subjects with any annual ED use did not increase significantly with greater cognitive impairment: cognitively intact (16.9%), MCI (26.1%), and ADRD (28.9%) (p = 0.072). Average number of ED visits increased similarly: cognitively intact (0.27, SD 0.72), MCI (0.41, SD 0.91), and ADRD (0.55, SD 1.25) (p = 0.059). Multivariate logistic regression results showed that patients with MCI (odds ratio (OR) 1.62; CI = 0.87-3.00) and ADRD (OR 1.84; CI = 0.98-3.46) did not significantly differ from cognitively intact adults in any ED use. Multivariate negative binomial regression found patients with MCI (incidence rate ratio (IRR) 1.38; CI = 0.79-2.41) and ADRD (IRR 1.76, CI = 1.00-3.10) had elevated but non-significant risk of an ED visit compared to cognitively intact individuals. CONCLUSION Though there was no significant difference in ED use in this small sample from one health system, our estimates are comparable to other published work. Results suggested a trend towards higher utilization among adults with MCI or ADRD compared to those who were cognitively intact. We must confirm our findings in other settings to better understand how to optimize systems of acute illness care for individuals with MCI and ADRD.

Abstract
OBJECTIVE To examine racial differences in the frequency of schizophrenia diagnosis codes used among nursing home (NH) residents with Alzheimer's Disease and Related Dementias (ADRD), pre and post the implementation of public reporting of antipsychotic use in NHs. METHODS The 2011-2017 Minimum Data Set and Medicare Master Beneficiary Summary File were linked. We identified long-stay NH residents (i.e., those who had quarterly or annual assessments) with ADRD aged 55 years and older (N = 7,734,348). Outcome variable was defined as the diagnosis of schizophrenia documented in the MDS assessments. Main variables of interest included individual race (black versus white), the percent of blacks in a NH and time trend. Multivariate regressions were estimated. RESULTS The frequency of schizophrenia diagnosis codes among NH residents with ADRD steadily increased over the study period, and blacks experienced a greater increase than their white counterparts. For example, the overall likelihood of having schizophrenia diagnosis increased 1.9 percentage points (95% confidence interval [CI]: 0.019, 0.020, p < 0.01) from 2011 to 2017 among whites, while blacks had an addition 1.3 percentage points increase (95% CI: 0.011, 0.015, p < 0.01). The increase in the likelihood of having schizophrenia diagnosis code was higher in NHs with higher percent of blacks: the increase from 2011 to 2017 was 2.6 percentage point (95% CI: 0.023, 0.029, p < 0.01) higher in NHs with the highest percent of blacks, compared to NHs with lowest percent of blacks. Racial differences in the growth of schizophrenia diagnosis also existed within a NH after accounting for NH factors. CONCLUSION Following the implementation of public reporting of antipsychotic use in NH, black residents experienced a greater increase in the likelihood of having schizophrenia diagnosis than white NH residents. NHs with a higher proportion of blacks had a greater increase in schizophrenia diagnosis, and blacks experienced an increased likelihood of schizophrenia diagnosis than whites within a NH. Further research is needed to determine a causal relationship between the federal policy mandating public reporting and disparities in schizophrenia diagnostic coding.

Abstract
BACKGROUND The Medicare Advantage (MA) program is rapidly growing. Limited evidence exists about the care experiences of MA beneficiaries with Alzheimer's Disease and Related Dementia (ADRD). Our objective was to compare care experiences for MA beneficiaries with and without ADRD. METHODS We examined MA beneficiaries who completed the Medicare Advantage Consumer Assessment of Healthcare Providers and Systems (CAHPS) and used inpatient, nursing home, or home health services in the past 3 years. We classified beneficiaries with ADRD using the presence of diagnosis codes in hospitals, nursing homes, and home health records. Our key measures included overall ratings of care and health plan, and indices of receiving timely care, care coordination, receiving needed care, and customer service. We compared differences between beneficiaries with and without ADRD using regression analysis adjusting for demographic, health, and plan characteristics, and stratifying by proxy response status. RESULTS Among beneficiaries sampled by CAHPS, 22.2% with ADRD completed the survey compared to 38.5% without ADRD. Among proxy responses, beneficiaries with ADRD were 4.2 (95% CI: 0.1-8.4) percentage points less likely to report a high score for receiving needed care, and 3.5 percentage points (95% CI: 0.2-6.9) less likely to report a high score for customer service. Among non-proxy responses, those with ADRD were 9.0 (95% CI: 5.5-12.5) percentage points less likely to report a high score for needed care, and 8.5 (95% CI: 5.4-11.5) percentage points less likely to report a high score for customer service. CONCLUSIONS ADRD respondents to the CAHPS were more likely to be excluded from CAHPS performance measures because they did not meet eligibility requirements and rates of non-response were higher. Among responders with or without a proxy, MA enrollees with an ADRD diagnosis reported worse care experiences in receiving needed care and in customer service than those without an ADRD diagnosis.

Abstract
BACKGROUND Even small improvements in modifiable Alzheimer's disease and related dementias (ADRD) risk factors could lead to a substantial reduction of dementia cases. AIMS To determine if self-reported functional limitation associates with ADRD symptoms 4-18 years later. METHODS We conducted a prospective longitudinal study using the Health and Retirement Study of adults aged 51-59 years in 1998 without symptoms of ADRD by 2002 and followed them to 2016. Main exposure variables were difficulty with activities of daily living, mobility, large muscle strength, gross motor and upper limb activities. The outcome was incident ADRD identified by the Lange-Weir algorithm, death, or alive without ADRD. We fit two GEE multinomial models for each measure: (1) baseline measure of function and (2) change in function over time. RESULTS In the model with baseline only and outcome, only difficulty with mobility associated with future ADRD across levels of difficulty with near dose-response effect (risk ratios (RR) difficulty with 1-5 functions respectively, compared with no difficulty: 1.82; 2.70; 1.73 2.81; 4.03). Mobility also significantly associated with ADRD when allowing for change over time among those with 3, 4 or 5 versus no mobility limitations (RR 1.76; 2.36; 2.37). DISCUSSION The results infer that an adult in midlife reporting difficulty with mobility as well as those with no mobility limitations in midlife but who later report severe limitations may be at increased risk of incident ADRD. CONCLUSIONS Self-reported measures of mobility limitation may be early indicators of ADRD and may be useful for public health planning.

Abstract
The genetic locus containing the WWOX and MAF genes was implicated as a clinical Alzheimer's disease (AD) risk locus in two recent large meta-analytic genome wide association studies (GWAS). In a prior GWAS, we identified a variant in WWOX as a suggestive risk allele for hippocampal sclerosis. We hypothesized that the WWOX/MAF locus may be preferentially associated with non-plaque- and non-tau-related neuropathological changes (NC). Data from research participants with GWAS and autopsy measures from the National Alzheimer's Coordinating Center and the Religious Orders Study and the Rush Memory and Aging Project were meta-analyzed. Notably, no variants in the locus were significantly associated with ADNC. However, several WWOX/MAF variants had significant adjusted associations with limbic-predominant age-related TDP-43 encephalopathy NC (LATE-NC), HS, and brain arteriolosclerosis. These associations remained largely unchanged after adjustment for ADNC (operationalized with standard semiquantitative staging), suggesting that these associations are independent of ADNC. Thus, WWOX genetic variants were associated pathologically with LATE-NC, not ADNC.

Abstract
BACKGROUND The ability to rate delirium severity is key to providing optimal care for persons with Alzheimer's Disease and Related Dementias (ADRD). Such ratings would allow clinicians to assess response to treatment, recovery time and prognosis, nursing burden and staffing needs, and to provide nuanced, appropriate patient-centered care. Given the lack of existing tools, we defined content domains for a new delirium severity instrument for use in individuals with mild to moderate ADRD, the DEL-S-AD. METHODS We built upon our previous study in which we created a content domain framework to inform development of a general delirium severity instrument, the DEL-S. We engaged a new expert panel to discuss issues of measurement in delirium and dementia and to determine which content domains from the prior framework were useful in characterizing delirium severity in ADRD. We also asked panelists to identify new domains. Our panel included eight interdisciplinary members with expertise in delirium and dementia. Panelists participated in two rounds of review followed by two surveys over 2 months. RESULTS Panelists endorsed the same content domains as for general delirium severity, including Cognitive, Level of Consciousness, Inattention, Psychiatric-Behavioral, Emotional Dysregulation, Psychomotor Features, and Functional; however, they excluded six of the original subdomains which they considered unhelpful in the context of ADRD: cognitive impairment; anxiety; fear/sense of unease; depression; gait/walking; and incontinence. Debated measurement challenges included assessment at one point in time versus over time, accounting for differences in clinical settings, and accurate assessment of symptoms related to delirium versus dementia. CONCLUSIONS By capturing a range of characteristics of delirium severity potentially present in patients with ADRD, a population that may already have attention, functional, and emotional changes at baseline, the DEL-S-AD provides a novel rating tool that will be useful for clinical and research purposes to improve patient care.

Abstract
BACKGROUND Data harmonization is a powerful method to equilibrate items in measures that evaluate the same underlying construct. There are multiple measures to evaluate dementia related behavioral symptoms. Pre-statistical harmonization of behavioral instruments in dementia research is the first step to develop a statistical crosswalk between measures. Studies that conduct pre-statistical harmonization of behavioral instruments rarely document their methods in a structured, reproducible manner. This is a crucial step which entails careful review, documentation and scrutiny of source data to ensure sufficient comparability between items prior to data pooling. Here, we document the pre-statistical harmonization of items measuring behavioral and psychological symptoms among people with dementia. We provide a box of recommended procedure for future studies. METHODS We identified behavioral instruments that are used in clinical practice, a national survey, and randomized trials of dementia care interventions. We rigorously reviewed question content and scoring procedures to establish sufficient comparability across items as well as item quality prior to data pooling. Additionally, we standardized coding to Stata-readable format, which allowed us to automate approaches to identify potential cross-study differences in items and low-quality items. To ensure reasonable model fit for statistical co-calibration, we estimated two-parameter logistic Item Response Theory models within each of the eight studies. RESULTS We identified 59 items from 11 behavioral instruments across the eight datasets. We found considerable cross-study heterogeneity in administration and coding procedures for items that measure the same attribute. Discrepancies existed in terms of directionality and quantification of behavioral symptoms for even seemingly comparable items. We resolved item response heterogeneity, missingness and skewness, conditional dependency prior to estimation of item response theory models for statistical co-calibration. We used several rigorous data transformation procedures to address these issues, including re-coding and truncation. CONCLUSIONS This study highlights the importance of each aspect involved in the pre-statistical harmonization process of behavioral instruments. We provide guidelines and recommendations for how future research may detect and account for similar issues in pooling behavioral and related instruments.

Abstract
BACKGROUND Previous research demonstrated an increase in the reporting of schizophrenia diagnoses among nursing home (NH) residents after the Centers for Medicare & Medicaid Services National Partnership to Improve Dementia Care. Given known health and healthcare disparities among Black NH residents, we examined how race and Alzheimer's and related dementia (ADRD) status influenced the rate of schizophrenia diagnoses among NH residents following the partnership. METHODS We used a quasi-experimental difference-in-differences design to study the quarterly prevalence of schizophrenia among US long-stay NH residents aged 65 years and older, by Black race and ADRD status. Using 2011-2015 Minimum Data Set 3.0 assessments, our analysis controlled for age, sex, measures of function and frailty (activities of daily living [ADL] and Changes in Health, End-stage disease and Symptoms and Signs scores) and behavioral expressions. RESULTS There were over 1.2 million older long-stay NH residents, annually. Schizophrenia diagnoses were highest among residents with ADRD. Among residents without ADRD, Black residents had higher rates of schizophrenia diagnoses compared to their nonblack counterparts prior to the partnership. Following the partnership, Black residents with ADRD had a significant increase of 1.7% in schizophrenia as compared to nonblack residents with ADRD who had a decrease of 1.7% (p = 0.007). CONCLUSIONS Following the partnership, Black NH residents with ADRD were more likely to have a schizophrenia diagnosis documented on their MDS assessments, and schizophrenia rates increased for Black NH residents with ADRD only. Further work is needed to examine the impact of "colorblind" policies such as the partnership and to determine if schizophrenia diagnoses are appropriately applied in NH practice, particularly for black Americans with ADRD.

Front Pharmacol 2021; 12:706762. [PMID: 34512340 PMCID: PMC8424001 DOI: 10.3389/fphar.2021.706762] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2021] [Accepted: 08/13/2021] [Indexed: 11/13/2022] Open
Abstract
Objective: The prevalence of Alzheimer's disease and related dementias (ADRD) in women is higher than men. However, the knowledge of gender disparity in ADRD treatment is limited. Therefore, this study aimed to determine the gender disparities in the receipt of anti-dementia medications among Medicare beneficiaries with ADRD in the U.S. Methods: We used data from the Medicare Current Beneficiary Survey 2016. Anti-dementia medications included cholinesterase inhibitors (ChEIs; including rivastigmine, donepezil, and galantamine) and N-methyl-D-aspartate (NMDA) receptor antagonists (including memantine). Descriptive analysis and multivariate logistic regression models were implemented to determine the possible gender disparities in the receipt of anti-dementia medications. Subgroup analyses were conducted to identify gender disparities among beneficiaries with Alzheimer's disease (AD) and those with only AD-related dementias. Results: Descriptive analyses showed there were statistically significant differences in age, marital status, and Charlson comorbidities index (CCI) between Medicare beneficiaries who received and who did not receive anti-dementia medications. After controlling for covariates, we found that female Medicare beneficiaries with ADRD were 1.7 times more likely to receive anti-dementia medications compared to their male counterparts (odds ratio [OR]: 1.71; 95% confidence interval [CI]: 1.19-2.45). Specifically, among Medicare beneficiaries with AD, females were 1.2 times more likely to receive anti-dementia medications (Odds Radio: 1.20; 95% confidence interval: 0.58-2.47), and among the Medicare beneficiaries with only AD-related dementias, females were 1.9 times more likely to receive anti-dementia medications (OR: 1.90; 95% CI: 1.23-2.95). Conclusion: Healthcare providers should be aware of gender disparities in receiving anti-dementia medications among patients with ADRD, and the need to plan programs of care to support both women and men. Future approaches to finding barriers of prescribing, receiving and, adhering to anti-dementia medications by gender should include differences in longevity, biology, cognition, social roles, and environment.

The Internet-Based Conversational Engagement Clinical Trial (I-CONECT) in Socially Isolated Adults 75+ Years Old: Randomized Controlled Trial Protocol and COVID-19 Related Study Modifications. Front Digit Health 2021; 3:714813. [PMID: 34713183 PMCID: PMC8521795 DOI: 10.3389/fdgth.2021.714813] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2021] [Accepted: 07/15/2021] [Indexed: 11/15/2022] Open
Abstract
Background: Increasing social interactions through communication technologies could offer a cost-effective prevention approach that slows cognitive decline and delays the onset of Alzheimer's disease. This paper describes the protocol of an active project named "Internet-based conversational engagement clinical trial (I-CONECT)" (ClinicalTrials.gov: NCT02871921). The COVID-19 pandemic related protocol modifications are also addressed in the current paper. Methods: I-CONECT is a multi-site, assessor-blind, randomized controlled behavioral intervention trial (RCT). We aim to randomize 320 socially isolated adults 75+ years old [160 Caucasian and 160 African American participants, 50:50 split between those with normal cognition and mild cognitive impairment (MCI)] recruited from the community to either the video chat intervention group or the control group (1:1 allocation). Those in the video chat group receive a computer and Internet service for the duration of the study, which they use to video chat with study staff for 30 min/day 4×/week for 6 months (high dose), and then 2×/week for an additional 6 months (maintenance dose). Both video chat and control groups have a brief (about 10 min) telephone check-in with study staff once per week. The primary outcome is the change in global cognitive function measured by Montreal Cognitive Assessment (MoCA) from baseline to 6 months. Secondary outcomes include changes in cognition in memory and executive function domains, emotional well-being measured by NIH Toolbox emotional battery, and daily functional abilities assessed with the Revised Observed Tasks of Daily Living (OTDL-R). Eligible participants have MRIs at baseline and 6 months. Participants contribute saliva for genetic testing (optional consent), and all video chats, weekly check-in calls and neuropsychological assessment sessions are recorded for speech and language analysis. The pandemic halted research activities and resulted in protocol modifications, including replacing in-person assessment with remote assessment, remote deployment of study equipment, and revised targeted sample size. Discussion: This trial provides user-friendly hardware for the conversational-based intervention that can be easily provided at participants' homes. The trial aspires to use age and culture-specific conversational materials and a related platform developed in this trial for enhancing cognitive reserve and improving cognitive function.

Longitudinal Comparison of Stability and Sensitivity in Quality of Life Scores Among Nursing Home Residents With and Without Diagnoses of Alzheimer's Disease and Related Dementias.

Abstract
BACKGROUND AND OBJECTIVES Prevalence of nursing home residents with Alzheimer's disease and related dementias (ADRD) has increased along with a growing consensus that person-centered ADRD care in nursing homes should maximize quality of life (QoL). However, concerns about whether residents with ADRD can make appropriate QoL judgments persist. This study assesses the stability and sensitivity of a self-reported, multidomain well-being QoL measure for nursing home residents with and without ADRD. RESEARCH DESIGN AND METHODS This study linked the 2012-2015 Minnesota Nursing Home Resident QoL and Satisfaction with Care Survey, Minimum Data Set 3.0 (nursing home assessments), and Minnesota Department of Human Services Cost Reports. The QoL survey included cohort-resident pairs who participated for 2 consecutive years (N = 12 949; 8 803 unique residents from 2012-2013, 2013-2014, and 2014-2015 cohorts). Change in QoL between 2 years was conceptualized as stable when within 1.5 SD of the sample average. We used linear probability models to estimate associations of ADRD/Cognitive Function Scale status with the stability of QoL summary and domain scores (eg, social engagement) and the absolute change in QoL summary score, controlling for resident and facility characteristics. RESULTS Most (86.82%) residents had stable QoL summary scores. Residents with moderate to severe cognitive impairment, irrespective of ADRD, were less likely to have stable summary scores than cognitively capable residents without ADRD (p < .001), but associations varied by QoL domains. Among those with stable summary QoL scores, changes in health/functional status were associated with absolute changes in summary QoL score (p < .001), suggesting sensitivity of the QoL measure. DISCUSSION AND IMPLICATIONS QoL scores were similarly stable over time for most residents with and without ADRD diagnoses and were sensitive to changes in health/functional status. This self-reported QoL measure may be appropriate for nursing home residents, regardless of ADRD diagnosis, and can efficaciously be recommended to other states.

Abstract
INTRODUCTION Understanding rural-urban variation in the diagnostic incidence and prevalence of Alzheimer's disease and related dementias (ADRD) will inform policies to improve timely diagnosis and access to supportive services for older adults in rural communities. METHODS Using 2008 to 2015 national claims data for fee-for-service Medicare beneficiaries (roughly 170 million person-years), we computed unadjusted and adjusted diagnostic incidence and prevalence estimates for ADRD in metropolitan, micropolitan, and rural counties, and examined differences in survival rates. RESULTS Risk-adjusted ADRD diagnostic incidence was higher in rural versus metropolitan counties despite lower prevalence. Among beneficiaries diagnosed with ADRD in 2008, metropolitan county residents experienced longer survival compared to residents in rural and micropolitan counties. DISCUSSION These data suggest that older adults in rural communities may be underdiagnosed with ADRD, and/or diagnosed at later stages of dementia. Further work is needed to develop strategies to reduce this disparity.

Abstract
OBJECTIVES Limited cohort studies have assessed the association between uncontrolled pain and risk for behavioral and psychological symptoms of dementia (BPSDs). We conducted a longitudinal cohort study to examine whether associations exist between uncontrolled pain and risk for 2 common BPSDs-depression and behavioral symptoms-among long-term care (LTC) residents with Alzheimer disease and related dementia (ADRD). DESIGN This retrospective cohort study analyzed quarterly data from the 5% Medicare sample linked to Minimum Data Set (MDS) 3.0 between January 1, 2011, and December 31, 2015. SETTING AND PARTICIPANTS LTC residents aged 50 years or older with ADRD who had chronic pain and at least 2 quarterly MDS 3.0 assessments. METHODS LTC residents were followed up quarterly from first observed quarterly MDS 3.0 until first outcome event or last observed quarterly MDS 3.0. Uncontrolled pain was defined as numerical rating scale >4, verbal descriptor scale of moderate or severe pain, or ≥1 pain indicators on the Checklist of Nonverbal Pain Indicators. Depression was defined as ≥10 on the Patient Health Questionnaire 9; behavioral symptoms were defined as the presence of psychotic (delusions or hallucinations) or disruptive behaviors (rejection of care, or physical, verbal, or other aggressive behaviors). Generalized linear models (GLMs) with marginal structural modeling (MSM) stabilized weights were used to examine uncontrolled pain and outcome risk. RESULTS The incidence rate of depression and behavioral symptoms during follow-up was 9.4 and 23.1 per 100 resident-years, respectively. Results from the MSM-GLMs showed that LTC residents with uncontrolled pain had a higher risk than those with controlled pain for developing depression [hazard ratio 1.67, 95% confidence interval (CI) 1.54-1.81] and behavioral symptoms (hazard ratio 1.28, 95% CI 1.19-1.37). CONCLUSIONS AND IMPLICATIONS Uncontrolled pain was associated with elevated risk for depressive and behavioral symptoms in dementia, underscoring the importance of pain assessment and control among LTC residents with ADRD.

Abstract
BACKGROUND To determine the incidence of homelessness among Veterans diagnosed with Alzheimer's disease and related dementias (ADRD). METHODS We used Veterans Affairs (VA) administrative records to identify Veterans with a new ADRD diagnosis anytime between 2010-2019. Among these Veterans, we calculated the incidence of homelessness, and estimated the association between demographics, comorbidities and hazard of homelessness. RESULTS The incidence rate of homelessness was highest for Veterans diagnosed with ADRD between 18-49 years of age (14.9 per 1,000 person-years; 95%CI: 13.6, 16.3) and lowest for Veterans diagnosed with ADRD at 90+ years (0.3 per 1,000 person-years; 95%CI: 0.2, 0.4). The adjusted hazard ratio of homelessness was higher for unmarried Veterans, and those with alcohol use disorder, substance use disorder, liver disease, depression, hypertension, lung disease, post-traumatic stress disorder and psychoses. CONCLUSIONS Younger age and being unmarried at the time of ADRD diagnosis are associated with a greater risk of experiencing homelessness.

Abstract
BACKGROUND/OBJECTIVES We sought to compare the post-acute and long-term care experience of Medicare beneficiaries with and without Alzheimer Disease and Related Dementias (ADRD), and whether differences changed from January 1, 2007 to September 30, 2015. DESIGN Retrospective cross-sectional trend study using Medicare claims linked to the Centers for Medicare & Medicaid Services' (CMS) Minimum Data Set. SETTING CMS-certified skilled nursing facilities (skilled nursing facility (SNF), n = 17,043). PARTICIPANTS Fee-for-service Medicare beneficiaries aged ≥66 years (n = 6,614,939) discharged from a hospital to a SNF who had not lived in a nursing home during the year before hospitalization. MEASUREMENTS ADRD was defined by the Chronic Condition Data Warehouse. Outcome measures included: (1) successful discharge defined as being in SNF less than 90 days, then discharged back to the community, alive without subsequent inpatient health care for 30 continuous days; (2) became long-stay resident in SNF; (3) death in SNF within 90 days; (4) hospital readmission within 30 days of entering SNF; and (5) transferred to another nursing home within 30 days of entering SNF. RESULTS Successful discharge of beneficiaries with ADRD increased from 43.4% in 2007 to 53.9% in 2015 (average annual percent change (AAPC) = 2.1 (95% CI = 2.0-2.2)); those without ADRD also increased (from 59.1% to 63.6%, AAPC = 0.9 (95% CI = 0.7-1.1)) but not as fast as those with ADRD (P < .01). The proportion of all beneficiaries who became long-stay or were readmitted to the hospital decreased (P < .05). The proportion with ADRD who became long-stay was nearly three times higher than those without throughout the study (15.0% vs 5.5% in 2007; 11.3% vs 4.3% in 2015). CONCLUSION Though disparity in ADRD in becoming long-stay residents remains, the increase in successful discharges among those with ADRD also stresses the increasing importance of community as a care setting for adults with ADRD.

Abstract
OBJECTIVE Explore within and across nursing home (NH) racial disparities in end-of-life (EOL) hospitalizations for residents with Alzheimer's disease or related dementia (ADRD), and examine whether severe cognitive impairment influences these relationships. DESIGN Observational study merging, at the individual level, C2014-2017 national-level Minimum Data Set (MDS), Medicare Beneficiary Summary Files (MBSF), and Medicare Provider Analysis and Review (MedPAR). Nursing Home Compare (NHC) was also used. SETTING Long-stay residents who died in a NH or a hospital within 8 days of discharge. PARTICIPANTS Analytical sample included 665,033 decedent residents with ADRD in 14,595 facilities. MAIN OUTCOMES AND MEASURES The outcome was hospitalization within 30 days of death. Key independent variables were race, severe cognitive impairment, and NH-level proportion of black residents. Other covariates included socio-demographics, dual eligibility, hospice enrollment, and chronic conditions. Facility-level characteristics were also included (e.g. profit status, staffing hours, etc.). We fit linear probability models with robust standard errors, fixed and random effects. RESULTS Compared to whites, black decedents had a significantly (p < 0.01) higher risk of EOL hospitalizations (7.88%). Among those with severe cognitive impairment, whites showed a lower risk of hospitalizations (6.04%). But EOL hospitalization risk among blacks with severe cognitive impairment was still significantly elevated (β = 0.0494; p < 0.01). A comparison of the base model with the fixed and random-effects models showed statistically significant hospitalization risk by decedent's race both within and across facilities. CONCLUSIONS AND RELEVANCE We found disparities between black and white residents with ADRD both within and across facilities. The within-facility disparities may be due to residents' preferences and/or NH practices that contribute to differential treatment. The across facility differences point to the overall quality of care disparities in homes with a higher prevalence of black residents. Persistence of such systemic disparities among the most vulnerable individuals is extremely troubling.

Abstract
BACKGROUND Alzheimer's Disease and Related Dementias (ADRD) clinical trials require multidisciplinary expertise in medicine, biostatistics, trial design, biomarkers, ethics, and informatics. OBJECTIVES To provide focused interactive training in ADRD clinical trials to a diverse cadre of investigators. DESIGN The Institute on Methods and Protocols for Advancement of Clinical Trials in ADRD (IMPACT-AD) is a novel multidisciplinary clinical trial training program funded by the National Institute on Aging and the Alzheimer's Association with two educational tracks. The Professionals track includes individuals who fill a broad variety of roles including clinicians, study coordinators, psychometricians, and other study professionals who wish to further their knowledge and advance their careers in ADRD trials. The Fellowship track includes current and future principal investigators and focuses on the design, conduct and analysis of ADRD clinical trials. SETTING The 2020 inaugural iteration of IMPACT-AD was held via Zoom. PARTICIPANTS Thirty-five trainees (15 Fellowship track; 20 Professionals track) were selected from 104 applications (34% acceptance rate). Most (n=25, 71%) identified as female. Fifteen (43%) were of a non-white race; six (18%) were of Hispanic ethnicity; eight (23%) indicated they were the first person in their family to attend college. MEASUREMENTS Participants completed daily evaluations as well as pre- and post-course assessments of learning. RESULTS Across topic areas, >90% of trainees evaluated their change in knowledge based on the lectures as "very much" or "somewhat increased." The mean proportion correct responses in pre- and post-course assessments increased from 55% to 75% for the Professionals track and from 54% to 78% for the Fellowship track. CONCLUSIONS IMPACT-AD successfully launched a new training opportunity amid a global pandemic that preliminarily achieved the goals of attracting a diverse cohort and providing meaningful training. The course is funded through 2025.

Abstract
There has been supporting evidence that older adults with underlying health conditions form the majority of the fatal cases in the current novel coronavirus disease (COVID-19) pandemic. While the impact of COVID-19 is affecting the general public, it is clear that these distressful experiences will be magnified in older adults, particularly people living with Alzheimer's disease and related dementia (ADRD), making them the most vulnerable group during this time. People with differing degrees of ADRD are especially susceptible to the virus, not only because of their difficulties in assessing the threat or remembering the safety measures, but also because of the likelihood to be subject to other risk factors, such as lack of proper care and psychological issues. Therefore, in this article, we will discuss the challenges related to home-based care for people with ADRD during a pandemic and propose a formulation of systematic solutions to address these challenges and to alleviate the social and economic impact resulting from the crisis.

Abstract
OBJECTIVE Previous research has found that having a spouse with Alzheimer's disease and related dementias (ADRD) is associated with higher health care expenditures, however it is unclear if this difference remains after accounting for the demographics and health status of the non-ADRD spouse. This paper aims to estimate the adjusted incremental health care expenditures of having a spouse with ADRD. DESIGN Cross-sectional study of publicly available survey data (2003-2017 Medical Expenditure Panel Survey). SETTING Representative sample of U.S. households. PARTICIPANTS Community-dwelling and married older adults (n = 28,356). MEASUREMENT Two-part models and recycled prediction techniques to estimate the incremental effects of having a spouse with ADRD on annual health care expenditures, while adjusting for demographics, socioeconomic characteristics, and health conditions. RESULTS Spouses of older adults with ADRD were older, had worse perceived mental health, and had greater difficulties with activities of daily living, compared to older adults with cognitively normal spouses. Spouses of ADRD patients had significantly higher unadjusted total health care expenditures, however their adjusted incremental expenditure was not significantly greater. After controlling for demographics and health status, ADRD spouses had significantly higher home health care expenditures, but significantly lower outpatient expenditures. CONCLUSION Results suggested that the higher health care expenditures in older adults with ADRD spouses can be attributed to the higher rate of comorbidities, rate of functional limitations, and mean age in this group. The increased use of home health and decreased use of outpatient in this population suggests the importance of tailoring preventative health care and social services to meet the needs of this group.

Abstract
Accumulating evidence suggests that certain chronic pain conditions may increase risk for incident Alzheimer's disease and related dementias (ADRD). Rigorous longitudinal research remains relatively sparse, and the relation of overall chronic pain condition burden to ADRD risk remains little studied, as has the potential mediating role of sleep and mood disorders. In this retrospective cohort study, we investigated the association of common non-cancer chronic pain conditions (NCPC) at baseline to subsequent risk for incident ADRD, and assessed the potential mediating effects of mood and sleep disorders, using baseline and 2-year follow-up data using 11 pooled cohorts (2001-2013) drawn from the U.S. Medicare Current Beneficiaries Survey (MCBS). The study sample comprised 16,934 community-dwelling adults aged ≥65 and ADRD-free at baseline. NCPC included: headache, osteoarthritis, joint pain, back or neck pain, and neuropathic pain, ascertained using claims data; incident ADRD (N = 1149) was identified using claims and survey data. NCPC at baseline remained associated with incident ADRD after adjustment for sociodemographics, lifestyle characteristics, medical history, medications, and other factors (adjusted odds ratio (AOR) for any vs. no NCPC = 1.21, 95% confidence interval (CI) = 1.04-1.40; p = 0.003); the strength and magnitude of this association rose significantly with increasing number of diagnosed NCPCs (AOR for 4+ vs. 0 conditions = 1.91, CI = 1.31-2.80, p-trend < 0.00001). Inclusion of sleep disorders and/or depression/anxiety modestly reduced these risk estimates. Sensitivity analyses yielded similar findings. NCPC was significantly and positively associated with incident ADRD; this association may be partially mediated by mood and sleep disorders. Additional prospective studies with longer-term follow-up are warranted to confirm and extend our findings.
