Background: Alzheimer's disease is the most common type of dementia and is responsible for up to 80% of dementia diagnoses and is the sixth leading cause of death in the United States. An estimated 38,000 American Indian/Alaska Native (AI/AN) people aged ≥65 years were living with Alzheimer's disease and related dementias (ADRD) in 2020, a number expected to double by 2030 and quadruple by 2050. Administrative healthcare data from the Indian Health Service (IHS) were used to estimate ADRD among AI/AN populations. Methods: Administrative IHS healthcare data from federal fiscal years 2016 to 2020 from the IHS National Data Warehouse were used to calculate the count and rate per 100,000 AI/AN adults aged ≥45 years with at least one ADRD diagnosis code on their medical record. Results: This study identified 12,877 AI/AN adults aged ≥45 years with an ADRD diagnosis code, with an overall rate of 514 per 100,000. Of those, 1856 people were aged 45–64. Females were 1.2 times (95% confidence interval: 1.1–1.2) more likely than males to have a medical visit with an ADRD diagnosis code. Conclusions: Many AI/AN people with ADRD rely on IHS, tribal, and urban Indian health programs. The high burden of ADRD in AI/AN populations aged 45–64 utilizing IHS health services highlights the need for implementation of ADRD risk reduction strategies and assessment and diagnosis of ADRD in younger AI/AN populations. This study provides a baseline to assess future progress for efforts addressing ADRD in AI/AN communities. [ABSTRACT FROM AUTHOR]

BACKGROUND: Evidence linking gaseous air pollution to late-life brain health is mixed. OBJECTIVE: We explored associations between exposure to gaseous pollutants and brain magnetic resonance imaging (MRI) markers among Atherosclerosis Risk in Communities (ARIC) Study participants, with attention to the influence of exposure estimation method and confounding by site. METHODS: We considered data from 1,665 eligible ARIC participants recruited from four US sites in the period 1987–1989 with valid brain MRI data from Visit 5 (2011–2013). We estimated 10-y (2001–2010) mean carbon monoxide (CO), nitrogen dioxide (NO2), nitrogen oxides (NOx), and 8- and 24-h ozone (O3) concentrations at participant addresses, using multiple exposure estimation methods. We estimated site-specific associations between pollutant exposures and brain MRI outcomes (total and regional volumes; presence of microhemorrhages, infarcts, lacunes, and severe white matter hyperintensities), using adjusted linear and logistic regression models. We compared meta-analytically combined site-specific associations to analyses that did not account for site. RESULTS: Within-site exposure distributions varied across exposure estimation methods. Meta-analytic associations were generally not statistically significant regardless of exposure, outcome, or exposure estimation method; point estimates often suggested associations between higher NO2 and NOx and smaller temporal lobe, deep gray, hippocampal, frontal lobe, and Alzheimer disease signature region of interest volumes and between higher CO and smaller temporal and frontal lobe volumes. Analyses that did not account for study site more often yielded significant associations and sometimes different direction of associations. DISCUSSION: Patterns of local variation in estimated air pollution concentrations differ by estimation method. Although we did not find strong evidence supporting impact of gaseous pollutants on brain changes detectable by MRI, point estimates suggested associations between higher exposure to CO, NOx, and NO2 and smaller regional brain volumes. Analyses of air pollution and dementia-related outcomes that do not adjust for location likely underestimate uncertainty and may be susceptible to confounding bias. [ABSTRACT FROM AUTHOR]

The aim of this study is to enhance comprehension of the different types and features of dementia, including their symptoms, diagnosis and medical treatment, and to propose various evidence-based exercise interventions and their clinical applications tailored to each specific type of dementia. The theoretical review includes the analysis of publications in the scientific databases PubMed/Medline, Ebsco, Scielo, and Google. A total of 177 articles were found, of which 84 were studied in depth. With the prevalence of all forms of dementia projected to increase from 57.4 million in 2019 to 152.8 million in 2050, personalized treatment strategies are needed. This review discusses various forms of dementia, including their pathologies, diagnostic criteria, and prevalence rates. The importance of accurate diagnosis and tailored care is emphasized, as well as the effectiveness of physical exercise in improving cognitive function in dementia patients. For Alzheimer's, a combination of drug therapies and exercises is recommended to enhance cerebral blood flow and neurotransmitter activity. To improve cognitive and motor functions in Lewy body dementia, a combination of pharmacological and physical therapies is recommended. For managing frontotemporal dementia, a mix of medication and exercises aimed at emotion regulation, including aerobic exercises, and a unified protocol, is suggested. For mild cognitive impairment, aerobic and functional exercises are important in delaying cognitive decline and enhancing cognitive performance. In conclusion, individualized care and treatment plans tailored to the specific characteristics of each disease type can improve the quality of life for individuals with this condition and effectively manage this growing global health issue.

Cultural narratives shape how we think about the world, including how we decide when the end of life begins. Hospice care has become an integral part of the end‐of‐life care in the United States, but as it has grown, its policies and practices have also imposed cultural narratives, like those associated with the "six‐month rule" that the majority of the end of life takes place in the final six months of life. This idea is embedded in policies for a range of care practices and reimbursement processes, even though six months is not always a meaningful marker. In the case of people living with advanced dementia, six months is both too early in the trajectory to facilitate conversations and too late in the trajectory to ensure decision‐making capacity. This essay encourages scholars and policy‐makers to consider how cultural narratives may limit what they think is possible in care for people living with dementia. [ABSTRACT FROM AUTHOR]

Introduction: Action 3 of the UN Decade of Healthy Ageing plan is to deliver integrated care to improve older adults' lives. Integrated care is vital in meeting the complex needs of people with dementia but little is known about how this is or could be delivered in low and middle income countries (LMIC). This paper provides insights into previously unknown care system structures and on the potential and reality of delivering integrated care in Central America for people with dementia. Methods: A social network analysis (SNA) methodology was adopted to engage with providers of services for older adults and families with dementia in Guatemala, El Salvador, Honduras, Costa Rica and Panama. Sixty-eight (68) semi-structured interviews were completed, 57 with organisations and 11 with families. Results: Across the five countries there was evidence of fragmentation and low integration within the dementia care systems. A variety of services and types of providers are present in all five countries, and high levels of diversified connections exist among organisations of differing disciplines. However, unawareness among network members about other members that they could potentially form active links with is a barrier on the path to integration. Conclusion: This innovative and robust study demonstrates SNA can be applied to evaluate LMIC care systems. Findings provide baselines of system structures and insights into where resources are needed to fortify integration strategies. Results suggest that Central American countries have the building blocks in place to develop integrated care systems to meet the needs of people with dementia, but the links across service providers are opportunistic rather than context based coordinated integration policies.

Objectives In view of the growing number of older incarcerated persons in the United States, cognitive impairment represents one of the most challenging and costly health care issues facing the U.S. correctional system. This study examined the prevalence and correlates of this growing public health issue in the nation's largest prison system. Methods In this study of a random sample of 143 older (≥55 years) adults incarcerated in the Texas prison system, we assessed—using the Montreal Cognitive Assessment (MoCA)—the percentage of inmates who met the MoCA thresholds for mild cognitive impairment (MCI; <23) and dementia (<18). Due to sample size limitations, our multivariable analysis assessed the binary outcome, MoCA <23. Results Overall, 35.0% of our random sample of incarcerated older adults in Texas met the threshold for MCI and 9.1% met the threshold for dementia. After adjusting for covariates, study participants who were Black (odds ratio [OR] = 4.12, 95% confidence interval [CI] = 1.57–10.82), Hispanic (OR = 4.34, 95% CI = 1.46–12.93), and those with a diagnosis of major depressive disorder (8.56, 95% CI = 1.21–60.72) all had higher prevalence of a positive screen for MCI or dementia. Dementia was underdiagnosed in our study sample of incarcerated adults, with 15.4% of MoCA-diagnosed dementia patients having a dementia diagnosis documented in their medical records. Discussion Future studies of cognitive impairment in prisons and jails can inform health care planning and resource allocation, such as expansion of access to palliative care, advance care planning, and targeted cognitive screening in older age groups.

Objectives Several U.S. health surveillance surveys contain items related to self- and proxy reports of dementia and subjective memory complaints (SMC). Despite their similar content, these items differ in terminology, item specificity, and time frame. The goal of this study was to analyze whether item features might influence endorsement rates for dementia and SMC. Methods We calculated design-appropriate estimates for the endorsement of dementia and SMC across U.S.-based national surveys and employed pairwise comparisons to evaluate endorsement rates across surveys. We also examined item characteristics to explore possible effects on endorsement rates. Results Endorsement rates were wide-ranging for dementia (ranging from 2.7% to 9.9%) and SMC (5.6% to 46.6%). Pairwise comparisons revealed statistically significant differences on most dementia-related items (76%), and all SMC comparisons (100%). Items varied substantially in the terminology used to assess dementia and SMC (e.g. "dementia" vs "Alzheimer's disease") and used different time frames (e.g. "past month" vs "5 years"). Discussion National survey data on reported dementia and SMC can have important research, training, and policy implications, yet endorsement rates vary widely across surveys. That variability could emerge from subtle but influential item characteristics, and our findings highlight the need for item harmonization, in even their most basic characteristics. Standardizing items across national surveillance surveys facilitates comparison across surveys so that we can better understand the true burden of these conditions to inform public health initiatives.

Background: The quality of care of the 6.5 million Americans living with dementia has been suboptimal, leading to worse outcomes and higher costs. Few health systems have formal systems in place to guide the care of these patients. To help improve the care of persons living with dementia, we developed and preliminarily evaluated the effectiveness of electronic health record (EHR)-generated recommendations for patients with dementia. Methods: This quality improvement study was conducted from October 2020 through June 2022 at a single academic healthcare system and included patients identified as having dementia on their problem list and their physicians. Ten (seven outpatient and three inpatient) algorithms based on clinical logic and evidence were embedded in an EHR system to generate specific recommendations based on combinations of utilization, diagnosis, and medications. The number of each type of recommendation generated, and orders for each type of recommendation were recorded, as well as physician's perceptions of this approach. Results: Three thousand six hundred and nine recommendations on 763 patients were triggered by the algorithms in the outpatient setting, and 185 referrals were placed. The most common recommendations were for ongoing care through the UCLA Alzheimer's and Dementia Care program, Palliative Care, the Extensivist Clinic, Urogynecology, and Clinical Pharmacy. The most commonly acted upon by providers were recommendations for referral to Pharmacists and the UCLA Alzheimer's and Dementia Care program. The most common reason for not responding to specific recommendations was that these were not perceived as relevant to the patient. Compared to general medicine physicians, geriatricians felt more comfortable managing dementia care without a referral to a service (23% (95% CI 15%–34%) versus 3% (95% CI 0%–17%), p = 0.012) and less commonly felt the recommendation was appropriate (1% (95% CI 0%–7%) versus 13% (95% CI 4%–30%), p = 0.02). Conclusions: EHR-generated algorithms can help guide patients with dementia to appropriate clinical services. [ABSTRACT FROM AUTHOR]

Describe health concerns of Black Americans as they age and what influences their participation in aging and clinical research. Fifty participants attended focus groups and completed questionnaires to identify barriers to research participation and attitudes toward dementia screening. Bivariate correlations explored associations between barriers to research participation and attitudes toward dementia screening. Cancer, hereditary conditions, vascular conditions, memory disorders, and psychological disorders were the greatest health concerns. Time demands, mistrust, lack of knowledge about potential research, and stigma were identified as barriers for research participation. Incentives, better understanding of how proposed research will benefit the community, lifestyle modification studies, active presence of principal researchers/clinicians, and community investment were identified as factors to improve participation. Questionnaires revealed mistrust and religious beliefs to be among the primary barriers. Attitudes toward dementia screening reflected perceived stigma, suffering, and subsequent loss of independence. Higher barriers to participation were associated with perceived stigma and loss of independence related to dementia screening. Successfully recruiting Black Americans for aging and clinical research remains a challenge. This study identifies barriers to participation and offers suggestions for planning and recruitment.

Introduction: People with dementia have high rates of hospitalization, and a share of these hospitalizations might be avoidable with appropriate ambulatory care, also known as potentially preventable hospitalization (PAH). This study investigates the associations between continuity of care and healthcare outcomes in the following year, including all-cause hospitalization, PAHs, and healthcare costs in patients with dementia.Methods: This is a longitudinal retrospective cohort study of 69,658 patients with dementia obtained from the Taiwan National Health Insurance Research Database. The Continuity of Care Index (COCI) was calculated to measure the continuity of dementia-related visits across physicians. The PAHs were classified into five types as defined by the Medicare Ambulatory Care Indicators for the Elderly (MACIEs). Logistic regression models were used to examine the effect of COCI on all-cause hospitalizations and PAHs, while generalized linear models were used to analyze the effect of COCI on outpatient, hospitalization, and total healthcare costs.Results: The high COCI group was significantly associated with a lower likelihood of all-cause hospitalization than the low COCI group (OR = 0.848, 95%CI: 0.821-0.875). The COCI had no significant effect on PAHs but was associated with lower outpatient costs (exp(β) = 0.960, 95%CI: 0.941 ~ 0.979), hospitalization costs (exp(β) = 0.663, 95%CI: 0.614 ~ 0.717), total healthcare costs (exp(β) = 0.962, 95%CI: 0.945-0.980).Conclusion: Improving continuity of care for dementia-related outpatient visits is recommended to reduce hospitalization and healthcare costs, although there was no statistically significant effect of continuity of care found on PAHs.

Background: Cancer-related cognitive impairment (CRCI), a frequent effect of cancer and its treatments, shares common cognitive symptoms with dementia syndromes. Cross-sectional studies demonstrate an inverse relationship between cancer and dementia. However, the longitudinal relationship between dementia decline and cancer has not been investigated.Objective: To evaluate the association between cancer and longitudinal progression of dementia.Methods: We extracted electronic health record data from July 2003 to February 2020 from a single academic medical center. We identified dementia and cancer history prior to dementia using ICD-9/10 codes. We measured cognitive decline with the Alabama Brief Cognitive Screener (ABCs). We used adjusted linear mixed models to estimate baseline cognition and rate of progression by cancer history, including differences by race.Results: The study included 3,809 participants with dementia, of which 672 (17.6%) had cancer history. Those with cancer history had higher baseline cognition (β: 1.07, 95% CI: 0.45, 1.69), but similar rate of decline. Non-Hispanic Blacks had lower cognitive scores at baseline and throughout follow-up regardless of cancer status compared to non-Hispanic Whites and other races/ethnicities with and without cancer history.Conclusion: In this longitudinal retrospective study, participants with cancer history demonstrate better cognition at dementia diagnosis and no difference in cognitive decline than those without cancer history. Smoking and comorbidities attenuate this association and results indicate non-Hispanic Blacks have worse cognitive outcomes in dementia regardless of cancer history than other race/ethnicity groups. Further exploration of the role of smoking, comorbidities, and race/ethnicity on cancer and dementia-related cognitive decline is needed. [ABSTRACT FROM AUTHOR]

Background: Studies have demonstrated women to have a higher prevalence of dementia compared to men. However, sex differences in dementia incidence are controversial with conflicting reports showing women with higher, lower, or similar incidence. Source of difference may be due to clinical setting and lack of consideration of competing risk of death. We examined dementia incidence in a sample of the national Veteran population to determine differences by sex.Methods: We examined data from the Veterans Health Administration (VHA), the largest integrated health care system in the United States. We studied 947 797 Veterans aged ≥55 years (mean age: 69.9 ± 8.4, 3% female) evaluated in the VHA from October 1, 1999 to September 30, 2019. We estimated age-adjusted incidence rates of dementia (International Classification of Diseases, 9th and 10th Edition codes) by sex, and used Fine-Gray proportional hazards models with age as time scale to examine time to diagnosis, accounting for competing risk of death.Results: During the follow-up (mean 8.4 years), 11.3% (n = 106 977, 11.4% men and 8.0% women) of Veterans developed dementia. Age-adjusted incidence was 12.6/1 000 person-years for men and 12.7/1 000 person-years for women. Compared to male Veterans, risk dementia was slightly higher among females (hazard ratio = 1.15; 95% confidence interval: 1.10-1.20), and on average, female Veterans developed dementia 0.2 years earlier than male Veterans. After additional adjustment for race, education, medical, and psychiatric conditions, results were similar.Conclusions: Among older Veterans in a national cohort, women had a slightly increased risk for developing dementia compared to men after accounting for competing risk of death.

Background: The evidence base for understanding hospice use among persons with dementia is almost exclusively based on individuals with a primary terminal diagnosis of dementia. Little is known about whether comorbid dementia influences hospice use patterns. Objective: To estimate the prevalence of comorbid dementia among hospice enrollees and its association with hospice use patterns. Design: Pooled cross-sectional analysis of the nationally representative Health and Retirement Study (HRS) linked to Medicare claims. Subjects: Fee-for-service Medicare beneficiaries in the United States who enrolled with hospice and died between 2004 and 2016. Measurements: Dementia was assessed using a validated survey-based algorithm. Hospice use patterns were enrollment less than or equal to three days, enrollment greater than six months, hospice disenrollment, and hospice disenrollment after six months. Results: Of 3123 decedents, 465 (14.9%) had a primary hospice diagnosis of dementia and 943 (30.2%) had comorbid dementia and died of another illness. In fully adjusted models, comorbid dementia was associated with increased odds of hospice enrollment greater than six months (adjusted odds ratio [AOR] = 1.52, 95% confidence interval [CI]: 1.11–2.09) and hospice disenrollment following six months of hospice (AOR = 2.55, 95% CI: 1.43–4.553). Having a primary diagnosis of dementia was associated with increased odds of hospice enrollment greater than six months (AOR = 2.62, 95% CI: 1.86–3.68), hospice disenrollment (AOR = 1.82, 95% CI: 1.32–2.51), and hospice disenrollment following six months of hospice (AOR = 4.31, 95% CI: 2.37–7.82). Conclusion: Approximately 45% of the hospice population has primary or comorbid dementia and are at increased risk for long hospice enrollment periods and hospice disenrollment. Consideration of the high prevalence of comorbid dementia should be inherent in hospice staff training, quality metrics, and Medicare Hospice Benefit policies. [ABSTRACT FROM AUTHOR]

Background: Screening for dementia in relevant healthcare settings may help in identifying low cognitive functioning for comprehensive cognitive assessments and subsequent dementia treatment after diagnosis. Aims: This study sought to estimate the prevalence of no reported dementia-related diagnosis in a nationally-representative sample of older Americans with a cognitive impairment consistent with dementia (CICD) by healthcare utilization. Methods: The unweighted analytical sample included 1514 Americans aged ≥ 65 years that were identified as having a CICD without history of stroke, cancers, neurological conditions, or brain damage who participated in at least one-wave of the 2010–2016 waves of the Health and Retirement Study. An adapted Telephone Interview of Cognitive Status assessed cognitive functioning. Those with scores ≤ 6 had a CICD. Dementia-related diagnosis was self-reported. Respondents indicated if they visited a physician, received home healthcare, or experienced an overnight nursing home stay in the previous two years. Results: The prevalence of no reported dementia-related diagnosis in persons with a CICD who visited a physician was 89.9% (95% confidence interval (CI): 85.4%-93.1%). Likewise, the prevalence of no reported diagnosis in those with a CICD who received home healthcare was 84.3% (CI: 75.1–90.5%). For persons with a CICD that had an overnight nursing home stay, the prevalence of no reported dementia-related diagnosis was 83.0% (CI: 69.1–91.4%). Discussion: Although the prevalence of no reported dementia-related diagnosis in individuals with a CICD differed across healthcare settings, the prevalence was generally high nonetheless. Conclusions: We recommend increased awareness and efforts be given to dementia screenings in various clinical settings. [ABSTRACT FROM AUTHOR]

Background: Understanding the dynamics of epidemiologic trends in Alzheimer's disease (AD) and related dementias (ADRD) and their epidemiologic causes is vital to providing important insights into reducing the burden associated with these conditions.Objective: To model the time trends in age-adjusted AD/ADRD prevalence and incidence-based mortality (IBM), and identify the main causes of the changes in these measures over time in terms of interpretable epidemiologic quantities.Methods: Trend decomposition was applied to a 5%sample of Medicare beneficiaries between 1991 and 2017.Results: Prevalence of AD was increasing between 1992 and 2011 and declining thereafter, while IBM increased over the study period with a significant slowdown in its rate of growth from 2011 onwards. For ADRD, prevalence and IBM increased through 2014 prior to taking a downwards turn. The primary determinant responsible for declines in prevalence and IBM was the deceleration in the increase and eventual decrease in incidence rates though changes in relative survival began to affect the overall trends in prevalence/IBM in a noticeable manner after 2008. Other components showed only minor effects.Conclusion: The prevalence and IBM of ADRD is expected to continue to decrease. The directions of these trends for AD are not clear because AD incidence, the main contributing component, is decreasing but at a decreasing rate suggesting a possible reversal. Furthermore, emerging treatments may contribute through their effects on survival. Improving ascertainment of AD played an important role in trends of AD/ADRD over the 1991-2009/10 period but this effect has exhausted itself by 2017. [ABSTRACT FROM AUTHOR]

Background/Objectives: No data exist regarding the validity of International Classification of Disease (ICD)‐10 dementia diagnoses against a clinician‐adjudicated reference standard within Medicare claims data. We examined the accuracy of claims‐based diagnoses with respect to expert clinician adjudication using a novel database with individual‐level linkages between electronic health record (EHR) and claims. Design: In this retrospective observational study, two neurologists and two psychiatrists performed a standardized review of patients' medical records from January 2016 to December 2018 and adjudicated dementia status. We measured the accuracy of three claims‐based definitions of dementia against the reference standard. Setting: Mass‐General‐Brigham Healthcare (MGB), Massachusetts, USA. Participants: From an eligible population of 40,690 fee‐for‐service (FFS) Medicare beneficiaries, aged 65 years and older, within the MGB Accountable Care Organization (ACO), we generated a random sample of 1002 patients, stratified by the pretest likelihood of dementia using administrative surrogates. Intervention: None. Measurements: We evaluated the accuracy (area under receiver operating curve [AUROC]) and calibration (calibration‐in‐the‐large [CITL] and calibration slope) of three ICD‐10 claims‐based definitions of dementia against clinician‐adjudicated standards. We applied inverse probability weighting to reconstruct the eligible population and reported the mean and 95% confidence interval (95% CI) for all performance characteristics, using 10‐fold cross‐validation (CV). Results: Beneficiaries had an average age of 75.3 years and were predominately female (59%) and non‐Hispanic whites (93%). The adjudicated prevalence of dementia in the eligible population was 7%. The best‐performing definition demonstrated excellent accuracy (CV‐AUC 0.94; 95% CI 0.92–0.96) and was well‐calibrated to the reference standard of clinician‐adjudicated dementia (CV‐CITL <0.001, CV‐slope 0.97). Conclusion: This study is the first to validate ICD‐10 diagnostic codes against a robust and replicable approach to dementia ascertainment, using a real‐world clinical reference standard. The best performing definition includes diagnostic codes with strong face validity and outperforms an updated version of a previously validated ICD‐9 definition of dementia. [ABSTRACT FROM AUTHOR]

Background: Adult vaccinations may reduce risk for dementia. However, it has not been established whether tetanus, diphtheria, pertussis (Tdap) vaccination is associated with incident dementia.Methods: Hypotheses were tested in a Veterans Health Affairs (VHA) cohort and replicated in a MarketScan medical claims cohort. Patients were at least 65 years of age and free of dementia for 2 years prior to index date. Patients either had or did not have a Tdap vaccination by the start of either of the 2 index periods (2011 or 2012). Follow-up continued through 2018. Controls had no Tdap vaccination for the duration of follow-up. Confounding was controlled using entropy balancing. Competing risk (VHA) and Cox proportional hazard (MarketScan) models estimated the association between Tdap vaccination and incident dementia in all patients and age subgroups (65-69, 70-74, and ≥75 years).Results: VHA patients were, on average, 75.6 (SD ± 7.5) years of age, 4% female, and 91.2% were White. MarketScan patients were 69.8 (SD ± 5.6) years of age, on average and 65.4% were female. After controlling for confounding, patients with, compared to without, Tdap vaccination had a significantly lower risk for dementia in both cohorts (VHA: hazard ratio [HR] = 0.58; 95% confidence interval [CI]:0.54-0.63 and MarketScan: HR = 0.58; 95% CI:0.48-0.70).Conclusions: Tdap vaccination was associated with a 42% lower dementia risk in 2 cohorts with different clinical and sociodemographic characteristics. Several vaccine types are linked to decreased dementia risk, suggesting that these associations are due to nonspecific effects on inflammation rather than vaccine-induced pathogen-specific protective effects.

Background: Older adults with bipolar disorder (BD) have increased dementia risk, but signs of dementia are difficult to detect in the context of pre-existing deficits inherent to BD.Objective: To identify the emergence of indicators of early dementia in BD.Methods: One hundred and fifty-nine non-demented adults with BD from the National Alzheimer's Coordinating Center (NACC) data repository underwent annual neuropsychological assessment up to 14 years (54.0 months average follow-up). Cognitive performance was examined longitudinally with linear mixed-effects models, and yearly differences between incident dementia cases and controls were examined in the six years prior to diagnosis.Results: Forty participants (25.2%) developed dementia over the follow-up period ('incident dementia cases'). Alzheimer's disease was the most common presumed etiology, though this was likely a result of sampling biases within NACC. Incident dementia cases showed declining trajectories in memory, language, and speeded attention two years prior to dementia onset.Conclusion: In a sample of BD patients enriched for Alzheimer's type dementia, prodromal dementia in BD can be detected up to two years before onset using the same cognitive tests used in psychiatrically-healthy older adults (i.e., measures of verbal recall and fluency). Cognition in the natural course of BD is generally stable, and impairment or marked decline on measures of verbal episodic memory or semantic retrieval may indicate an early neurodegenerative process.

Background: Dementia screening is an important step for appropriate dementia-related referrals to diagnosis and treat possible dementia.Objective: We sought to estimate the prevalence of no reported dementia-related diagnosis in a nationally representative sample of older Americans with a cognitive impairment consistent with dementia (CICD).Methods: The weighted analytical sample included 6,036,224 Americans aged at least 65 years old that were identified as having a CICD without history of stroke, cancers, neurological conditions, or brain damage who participated in at least one-wave of the 2010-2016 Health and Retirement Study. The adapted Telephone Interview of Cognitive Status assessed cognitive functioning. Those with scores≤6 were considered as having a CICD. Healthcare provider dementia-related diagnosis was self-reported. Age, sex, educational achievement, and race and ethnicity were also self-reported.Results: The overall estimated prevalence of no reported dementia-related diagnosis for older Americans with a CICD was 91.4%(95%confidence interval (CI): 87.7%-94.1%). Persons with a CICD who identified as non-Hispanic black had a high prevalence of no reported dementia-related diagnosis (93.3%; CI: 89.8%-95.6%). The estimated prevalence of no reported dementia-related diagnosis was greater in males with a CICD (99.7%; CI: 99.6%-99.8%) than females (90.2%; CI: 85.6%-93.4%). Moreover, the estimated prevalence of no reported dementia-related diagnosis for non-high school graduates with a CICD was 93.5%(CI: 89.3%-96.1%), but 90.9%(CI: 84.7%-94.7%) for those with at least a high school education.Conclusion: Dementia screening should be encouraged during routine geriatric health assessments. Continued research that evaluates the utility of self-reported dementia-related measures is also warranted. [ABSTRACT FROM AUTHOR]

Primary care is at the forefront of healthcare delivery. It is the site of disease prevention and health management and serves as the bridge between communities and the health care system As ethnographers of primary care, in this article we discuss what is gained by situating anthropological inquiry within primary care. We articulate how anthropologists can contribute to a better understanding of the issues that emerge in primary care. We provide a review of anthropological work in primary care and offer empirical data from two ethnographic case studies based in the United States, one focused on social risk screening in primary care and the other examining the diagnosis and care of people with dementia in primary care. Through these cases, we demonstrate how research of and within primary care can open important avenues for the study of the multidimensionality of primary care. This multidimensionality is apparent in the ways the medical field addresses the social and structural experiences of patients, scope of practice and disciplinary boundaries, and the intersection of ordinary and extraordinary medicine that emerge in the care of patients in primary care. • Demonstrates what is gained by situating anthropological inquiry within primary care. • Articulates how anthropologists contribute to understanding issues that emerge in primary care. • Provides empirical data from two ethnographic case studies based in primary care settings in the United States. • Primary care work in dementia and social risk address patients' social and structural experiences. • Discusses scope of practice and disciplinary boundaries that emerge in the care of patients in primary care.

Objectives This study provides the first comparison of trends in dementia prevalence in the U.S. population using 3 different dementia ascertainments/data sources: neuropsychological assessment, cognitive tests, and diagnosis codes from Medicare claims. Methods We used data from the nationally representative Health and Retirement Study and Aging, Demographics, and Memory Study, and a 20% random sample of Medicare beneficiaries. We compared dementia prevalence across the 3 sources by race, gender, and age. We estimated trends in dementia prevalence from 2006 to 2013 based on cognitive tests and diagnosis codes utilizing logistic regression. Results Dementia prevalence among older adults aged 70 and older in 2004 was 16.6% (neuropsychological assessment), 15.8% (cognitive tests), and 12.2% (diagnosis codes). The difference between dementia prevalence based on cognitive tests and diagnosis codes diminished in 2012 (12.4% and 12.9%, respectively), driven by decreasing rates of cognitive test-based and increasing diagnosis codes-based dementia prevalence. This difference in dementia prevalence between the 2 sources by sex and for age groups 75–79 and 90 and older vanished over time. However, there remained substantial differences across measures in dementia prevalence among blacks and Hispanics (10.9 and 9.8 percentage points, respectively) in 2012. Discussion Our results imply that ascertainment of dementia through diagnosis may be improving over time, but gaps across measures among racial/ethnic minorities highlight the need for improved measurement of dementia prevalence in these populations.

Background: The changing technological environment is reflected in regular updates made to the everyday technology (ET) use questionnaire (ETUQ). Newly added ETs may not present comparable challenges across countries and diagnoses. Aims: To identify whether country context, or dementia diagnosis, impact ETs' challenge level. Material and methods: 315 older adults from three countries were included; Sweden (n = 73), United States (n = 114), England (n = 128), and had a confirmed diagnosis of mild dementia (n = 99) or no known cognitive impairment (n = 216). Differential Items Functioning (DIF) analysis was performed on 88 ETs included in the ETUQ by country and diagnosis. The impact of DIF was evaluated in a Differential Test Functioning (DTF) analysis. Results: Nine items (10.2%) in the ETUQ showed statistically significant DIF between countries; five of which were public space ETs and none of which were information and communication technologies (ICTs). Three ICT items, and no others, showed significant DIF by diagnosis. The items' DIF was shown to have no impact upon person measures of ability to use ET in the DTF. Conclusions and significance: The utility of the ETUQ in occupational therapy practice and research internationally is highlighted through the stability of the challenge hierarchy and lack of impact on person measures.

Background: Few studies have examined patient characteristics and treatment patterns among patients with dementia and agitation in the United States (US).Objective: To examine real-world treatment patterns and characteristics of patients with agitation related to dementia who were treated with antipsychotics in US residential care and community-based settings.Methods: This retrospective chart review collected US physician-level data from patients 55 to 90 years old initiated on an antipsychotic medication for the treatment of agitation related to dementia from January 2018 to May 2018. Clinical characteristics and treatment patterns were assessed overall and stratified by residential care and community-based settings.Results: A total of 313 participating physicians, 59.5% of whom were primary care physicians, abstracted 801 patient charts (residential care: n = 312; community-based: n = 489). Of patients with agitation who were initiated on an antipsychotic, most patients (74.5%) were initiated within 3 months of the onset of their studied agitation episode, and 62.8% experienced multiple agitation episodes before initiation. While non-pharmacological therapies are recommended first-line approach for agitation in dementia, use of non-pharmacological therapy before initiation of antipsychotics was reported for only 37.8% of patients in residential care and 21.3% in community-based settings.Conclusion: Most patients were initiated on an antipsychotic treatment after multiple episodes of agitation and largely without initial non-pharmacological therapy, suggesting that current treatment guideline recommendations for first-line non-pharmacological intervention may not be adequately followed in clinical practice. Understanding the clinical burden and treatment patterns among dementia patients with agitation is imperative for effective disease management. [ABSTRACT FROM AUTHOR]

OBJECTIVES: Early recognition of dementia would allow patients and their families to receive care earlier in the disease process, potentially improving care management and patient outcomes, yet nearly half of patients with dementia are undiagnosed. Our aim was to develop and validate an electronic health record (EHR)‐based tool to help detect patients with unrecognized dementia (EHR Risk of Alzheimer's and Dementia Assessment Rule [eRADAR]). DESIGN: Retrospective cohort study. SETTING: Kaiser Permanente Washington (KPWA), an integrated healthcare delivery system. PARTICIPANTS: A total of 16 665 visits among 4330 participants in the Adult Changes in Thought (ACT) study, who undergo a comprehensive process to detect and diagnose dementia every 2 years and have linked KPWA EHR data, divided into development (70%) and validation (30%) samples. MEASUREMENTS: EHR predictors included demographics, medical diagnoses, vital signs, healthcare utilization, and medications within the previous 2 years. Unrecognized dementia was defined as detection in ACT before documentation in the KPWA EHR (ie, lack of dementia or memory loss diagnosis codes or dementia medication fills). RESULTS: Overall, 1015 ACT visits resulted in a diagnosis of incident dementia, of which 498 (49%) were unrecognized in the KPWA EHR. The final 31‐predictor model included markers of dementia‐related symptoms (eg, psychosis diagnoses, antidepressant fills), healthcare utilization pattern (eg, emergency department visits), and dementia risk factors (eg, cerebrovascular disease, diabetes). Discrimination was good in the development (C statistic =.78; 95% confidence interval [CI] =.76‐.81) and validation (C statistic =.81; 95% CI =.78‐.84) samples, and calibration was good based on plots of predicted vs observed risk. If patients with scores in the top 5% were flagged for additional evaluation, we estimate that 1 in 6 would have dementia. CONCLUSION: The eRADAR tool uses existing EHR data to detect patients with good accuracy who may have unrecognized dementia. J Am Geriatr Soc 68:103–111, 2019 [ABSTRACT FROM AUTHOR]

Cognitive impairment and dementia continue to threaten the aging population. Although no one is immune, certain groups, namely black older persons, are more likely to have a diagnosis of certain dementias. Because researchers have not found a purely biological reason for this disparity, they have turned to a biopsychosocial model. Specifically, black persons in the United States are more likely to live with social conditions that affect their stress levels which in turn affect physiological regulation leading to conditions that result in higher levels of cognitive impairment or dementia. Here we discuss some of these social conditions such as discrimination, education, and socioeconomic status, and how physiological dysregulation, namely allostatic load that can lead to cognitive impairment and dementia in black persons especially.

We examined how methods used for identifying dementia in administrative claims affected dementia incidence across racial/ethnic populations using a 100% sample of Medicare beneficiaries (n = 23,793,452). We found levels differed by method from 3.1% annual incidence to 3.6% in 2014. Dementia incidence declined from 2007 to 2014, but choice of method differentially impacted levels and trends by race/ethnicity. Methods using codes for dementia diagnosis and drugs to treat symptoms identified proportionally more Hispanics and Asians with dementia than other race/ethnicities, while codes for dementia diagnosis, drugs, and symptoms identified proportionally more whites and American Indians/Alaska Natives with dementia than other race/ethnicities.

In nursing homes (NHs), residents are at risk for malnutrition and weight loss. The purpose of this secondary data analysis was to examine the impact of resident cognitive status and level of feeding assistance provided by NH staff on resident's daily nutritional intake and body weight. As part of a large, multisite clinical trial (N = 786), residents with and without dementia were examined according to level of feeding assistance required during mealtimes (independent, set-up only, needs help eating) over a 21-day period. Outcomes analyzed were percent of meal intake by meal type (breakfast, lunch, dinner) and overall daily intake (meals + snacks/supplements). Residents with dementia who required meal set-up assistance had significantly lower meal intake for all three meals. Residents without dementia requiring meal set-up assistance experienced significantly lower intake for breakfast and dinner, but not lunch. When snacks and supplements were offered between meals, residents with dementia consumed approximately 163 additional calories/day, and residents without dementia consumed approximately 156 additional calories/day. This study adds new evidence that residents at greatest risk for low intake are those who are only provided set-up assistance for meals and/or have cognitive impairment. [ABSTRACT FROM AUTHOR]

Objective: To determine the prevalence of retinal microvascular signs and associations between retinal signs and cognitive status. Design: Cross‐sectional analysis of visit 5 (2011‐2013) of the Atherosclerosis Risk in Communities (ARIC) cohort. Data analysis took place November 30, 2017, to May 1, 2018. Setting: Biracial population‐based cohort from four US communities. Participants: A total of 2624 participants with a mean age of 76 years (SD = 5 years) (19% African American) with data on cognitive status and complete retinal examination. Measurements: Retinal signs measured with fundus photography. Cognitive status: normal cognition, mild cognitive impairment (MCI)/dementia with a primary diagnosis of Alzheimer disease (AD) without cerebrovascular disease (CVD), and MCI/dementia with a primary or secondary diagnosis of CVD (irrespective of AD). Results: Overall, 6% of the cohort had mild retinopathy and 2% had moderate/severe retinopathy. Of the cohort, 7% had microaneurysms, 6% had retinal hemorrhages, and 8% had arteriovenous (AV) nicking. There was a low prevalence of soft exudates (1%) and focal narrowing (1%). In weighted fully adjusted models, individuals with retinal hemorrhages had a two‐fold higher odds of all‐cause MCI/dementia (95% confidence interval [CI] = 1.3‐3.0; P =.001) and a 2.5‐fold higher odds (95% CI = 1.6‐3.9; P <.001) of MCI/dementia with CVD compared to individuals with no retinal hemorrhages. Individuals with AV nicking had a 1.6‐fold higher odds of MCI/dementia with CVD (95% CI = 1.0‐2.4) compared to individuals with no AV nicking (P <.05). There were no associations between retinal signs and MCI/dementia without CVD. Conclusion: Our findings are confirmatory of recent research, and suggest that retinal microvascular signs may reflect microvascular pathology in the brain, potentially contributing to dementia and earlier MCI. The low prevalence of retinal signs and modest associations with cognitive status, however, limit the current clinical utility of these findings. Further work is needed to determine whether more sophisticated imaging may detect more subtle retinal signs with higher sensitivity to identify individuals at risk of dementia.

Objective: To present normative performance data on the Modified Mini-Mental State (3MS) examination for healthy community-dwelling older individuals according to gender, age, education level, and ethno-racial group. Method: More than 19,000 generally healthy older men and women without a diagnosis of dementia were recruited from the general population in Australia and the U.S. for the ASPirin in Reducing Events in the Elderly (ASPREE) study. The 3MS exam was administered as part of the baseline screening and individuals scoring above 77 were eligible to participate. Results: The sample comprised 16,360 Australian whites, 1080 U.S. whites, 895 African-Americans and 316 Hispanic/Latinos. The median age of participants was 74 years (range 65–98), with an average of 12 years of education and 56% were female. Increasing age and fewer years of completed education were associated with lower scores on the 3MS. Women scored higher than men in most age and education categories. Differences across ethno-racial groups were found. With factor analysis, four factors were identified which accounted for 35% of the between-person variance in 3MS scores for white Australians. Conclusions: This large cohort of older individuals provides some of the most comprehensive 3MS normative data to be generated for whites (Australian and U.S.), Hispanic/Latinos and African-Americans, by age, gender, and educational attainment. These findings will serve as important reference standards for monitoring cognitive function in generally healthy older individuals, becoming increasingly important as this fraction of the population increases.

Background: Technology has multiple potential applications to dementia from diagnosis and assessment to care delivery and supporting ageing in place. Objectives: To summarise key areas of technology development in dementia and identify future directions and implications. Method: Members of the US Alzheimer's Association Technology Professional Interest Area involved in delivering the annual pre-conference summarised existing knowledge on current and future technology developments in dementia. Results: The main domains of technology development are as follows: (i) diagnosis, assessment and monitoring, (ii) maintenance of functioning, (iii) leisure and activity, (iv) caregiving and management. Conclusions: The pace of technology development requires urgent policy, funding and practice change, away from a narrow medical approach, to a holistic model that facilitates future risk reduction and prevention strategies, enables earlier detection and supports implementation at scale for a meaningful and fulfilling life with dementia.

Objectives: To examine how misidentification of dementia affects estimation of Medicare costs in a largely minority cohort of participants for whom accurate in‐person diagnoses are available. Design: Prospective cohort study. Setting: Washington Heights‐Inwood Columbia Aging Project, a multiethnic, population‐based, prospective study of cognitive aging of Medicare beneficiaries aged 65 and older. Participants: Individuals clinically diagnosed with dementia (n=495) and individuals clinically diagnosed without dementia (n=1,701). Measurements: Medicare claims‐identified dementia was defined according to the presence of any International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis codes for Alzheimer's disease and related dementias in all available claims during the study period. Participant characteristics associated with claims misidentification of dementia were estimated using logistic regression. Effects of dementia misidentification on Medicare expenditures were estimated using generalized linear models. Results: Medicare claims correctly identified 250 of the 495 (51%) dementia cases and 1,565 of the 1,701 (92%) nondementia cases. Sensitivity of claims‐identified dementia was 0.51, and specificity was 0.92. Average annual Medicare expenditures were $14,721 for a beneficiary with a clinical diagnosis of dementia, and $18,208 for a beneficiary with claim‐identified dementia, suggesting an overestimation of $3,487 per person per year when Medicare claims were used to identify dementia. Total annual expenditures for all beneficiaries with claims‐identified dementia were $258,707 lower than that for all those who were clinically diagnosed, suggesting an overall underestimation of total Medicare expenditures if Medicare claims were used to identify dementia. Different types of misidentification have different effects on dementia‐related cost estimates. Average annual expenditures per person were highest for false positives. Conclusion: Misidentification of dementia in Medicare claims is common. Using claims to identify dementia may result in significantly biased estimates of the cost of dementia.

Objectives: To investigate the natural history, cause of death, and end‐of‐life experiences of individuals diagnosed with dementia with Lewy bodies (DLB). Design: Twenty‐question online survey administered through the Lewy Body Dementia Association. Setting: United States. Participants: Caregivers, family, and friends of individuals who died in the past 5 years with a diagnosis of DLB (survey respondents: n = 658, 89% female, median age 50–69). Measurements: The survey included 3 questions about the respondent's background and 17 about the end‐of‐life experiences of the person with DLB. Topics included time from symptom onset and diagnosis to death, cause of death, advance directive completion, end‐of‐life education, hospice use, and location of death. Results were analyzed descriptively. Results: Most individuals with DLB died within 5 years of diagnosis (median 3–4 years). Respondents indicated that physicians rarely discussed what to expect at the end of life (40% total, but only 22% to a helpful degree) and that the caregiver usually initiated such conversations. Death was usually expected, but fewer than half of respondents felt prepared for what to expect. Seventy‐eight percent used hospice, usually at home or in skilled care, with wide variations in duration. Failure to thrive was the most common cause of death (65%), followed by pneumonia and swallowing difficulties (23%), other medical conditions (19%), and complications from falling (10%) (multiple causes allowed). Conclusion: Study results highlight a critical need for better prognostic counseling and education for persons and families living with DLB. The results of the current study can inform such counseling, but additional studies are needed to further explore expected prognosis of individuals diagnosed clinically with DLB and optimal use of palliative care services.

The article discusses the utility of brief cognitive testing in detecting clinical Alzheimer-type dementia (ATD) in adults with suspected cognitive impairment and distinguishing it from mild cognitive impairment (MCI) or normal cognition. Topics mentioned include accuracy of brief cognitive tests in distinguishing clinical ATD from MCI, sensitivity and specificity of clock drawing tests, and assessment for cognitive impairment in individuals concerned about their memory.

Background: Many older adults living with dementia have not been formally diagnosed. Even when clinicians document the diagnosis, patients and families may be unaware of the diagnosis. Knowledge of how individual characteristics affect detection and awareness of dementia is limited.Objective: To identify characteristics associated with dementia diagnosis and awareness of diagnosis.Design: Cross-sectional observational study.Participants: Five hundred eighty-five adults aged ≥ 65 in the National Health and Aging Trends Study who met assessment-based study criteria for probable dementia in 2011 and had 3 years of continuous, fee-for-service Medicare claims prior to 2011.Main Measures: Using multivariable logistic regression, we compared participants with undiagnosed versus diagnosed dementia (based on Medicare claims) on demographic, social/behavioral, functional, medical, and healthcare utilization characteristics. Among those diagnosed, we compared characteristics of participants unaware versus aware of the diagnosis (based on self or proxy report).Key Results: Among older adults with probable dementia, 58.7% were either undiagnosed (39.5%) or unaware of the diagnosis (19.2%). In adjusted analyses, individuals who were Hispanic (OR 2.48, 95% CI 1.19, 5.14), had less than high school education (OR 0.54 for at least high school education, 95% CI 0.32, 0.91), attended medical visits alone (OR 1.98, 95% CI 1.11, 3.51), or had fewer functional impairments (OR 0.79 for each impairment, 95% CI 0.69, 0.90) were more likely to be undiagnosed. Similarly, among those diagnosed, having less education (OR 0.42), attending medical visits alone (OR 1.97), and fewer functional impairments (OR 0.72) were associated with unawareness of diagnosis (all ps < 0.05).Conclusions: The majority of older adults with dementia are either undiagnosed or unaware of the diagnosis, suggesting shortcomings in detection and communication of dementia. Individuals who may benefit from targeted screening include racial/ethnic minorities and persons who have lower educational attainment, any functional impairment, or attend medical visits alone.

Background Patients with dementia form an increasing proportion of those entering hospice care. Little is known about the types of hospices serving patients with dementia and the patterns of hospice use, including timing of hospice disenrollment between patients with and without dementia. Objectives To characterize the hospices that serve patients with dementia, to compare patterns of hospice disenrollment for patients with dementia and without dementia, and to evaluate patient-level and hospice-level characteristics associated with hospice disenrollment. Methods We used data from a longitudinal cohort study (2008–2011) of Medicare beneficiaries (n = 149,814) newly enrolled in a national random sample of hospices (n = 577) from the National Hospice Survey and followed until death (84% response rate). Results A total of 7328 patients (4.9%) had a primary diagnosis of dementia. Hospices caring for patients with dementia were more likely to be for-profit, larger sized, provide care for more than 5 years, and serve a large (>30%) percentage of nursing home patients. Patients with dementia were less likely to disenroll from hospice in conjunction with an acute hospitalization or emergency department visit and more likely to disenroll from hospice after long enrollment periods (more than 165 days) as compared with patients without dementia. No significant difference was found between patients with and without dementia for disenrollment after shorter enrollment periods (less than 165 days). In the multivariable analyses, patients were more likely to be disenrolled after 165 days if they were served by smaller hospices and hospices that served a small percentage of nursing home patients. Conclusion Patients with dementia are significantly more likely to be disenrolled from hospice following a long enrollment period compared with patients without dementia. As the number of individuals with dementia choosing hospice care continues to grow, it is critical to address potential barriers to the provision of quality palliative care for this population near the end of life.

Objective: This study examines public perspectives toward sexual behavior within a heterosexually married couple in which one individual has dementia and resides in a long-term care facility. Method: Respondents included 318 adults in the Southern United States. Paired sample t tests were used to understand how the diagnosis of dementia statistically influenced participants' responses, and a logistic regression model was used to understand how a vignette character's sex and respondent characteristics influenced attitudes. Results: Fifty-eight percent of respondents believed that a sexual relationship should be permitted for an adult with dementia, and t tests revealed that dementia had a statistical effect on participants' responses. Sex of the vignette character was not a predictor of attitudes. Participant's qualitative rationales are offered for additional insight. Discussion: Respondents who felt that a couple should not engage in a sexual relationship commonly cited consent-related issues as their primary concern. Implications for policy development are discussed. [ABSTRACT FROM AUTHOR]

Because of the age of persons diagnosed with younger-onset Alzheimer's disease or other dementias (YOD), an important and as yet relatively little explored area of YOD, particularly in the United States, is the impact on young children of having a parent with YOD. After reviewing the small but growing research in this area, we report on findings from 12 in-depth interviews with children and well-parents in families with a parent with YOD on the experience and needs of children having a parent with this diagnosis. Children report disruption in many aspects of their lives: their developmental trajectory, emotional and psychological development, familial and broader social relationships, and financial stability. Despite these significant disruptions, and a dearth of information, resources, and services tailored to their individual and familial needs, these children demonstrate remarkable resilience and self-awareness. We discuss implications for interventions with these families. [ABSTRACT FROM AUTHOR]

Background: Clinical features of dementia (cognition, function, and behavioral/psychological symptoms [BPSD]) may differentially affect Medicare expenditures/health care utilization.Methods: We linked cross-sectional data from the Aging, Demographics, and Memory Study to Medicare data to evaluate the association between dementia clinical features among those with dementia and Medicare expenditures/health care utilization (n = 234). Cognition was evaluated using the Mini-Mental State Examination (MMSE). Function was evaluated as the number of functional limitations (0-10). BPSD was evaluated as the number of symptoms (0-12). Expenditures were estimated with a generalized linear model (log-link and gamma distribution). Number of hospitalizations, institutional outpatient visits, and physician visits were estimated with a negative binomial regression. Medicare covered skilled nursing days were estimated with a zero-inflated negative binomial model.Results: Cognition and BPSD were not associated with expenditures. Among individuals with less than seven functional limitations, one additional limitation was associated with $123 (95% confidence interval: $19-$227) additional monthly Medicare spending. Better cognition and poorer function were associated with more hospitalizations among those with an MMSE less than three and less than six functional limitations, respectively. BPSD had no effect on hospitalizations. Poorer function and fewer BPSD were associated with more skilled nursing among individuals with one to seven functional limitations and more than four symptoms, respectively. Cognition had no effect on skilled nursing care. No clinical feature was associated with institutional outpatient care. Of individuals with an MMSE less than 15, poorer cognition was associated with fewer physician visits. Among those with more than six functional limitations, poorer function was associated with fewer physician visits.Conclusions: Poorer function, not cognition or BPSD, was associated with higher Medicare expenditures.

The objective of this study is to validate two abridged versions of the mini-mental state examination (MMSE): one intended for use in face-to-face interviews, and the other developed for telephonic interviews, using data from Sweden and the US to validate the abridged scales against dementia diagnoses as well as to compare their performance to that of the full MMSE scale. The abridged versions were based on eight domains from the original MMSE scale. The domains included in the MMSE-SF were registration, orientation, delayed recall, attention, and visual spatial ability. In the MMSE-SF-C, the visual spatial ability item was excluded, and instead, one additional orientation item was added. There were 794 participants from the Swedish HARMONY study [mean age 81.8 (4.8); the proportion of cognitively impaired was 51 %] and 576 participants from the US ADAMS study [mean age 83.2 (5.7); the proportion of cognitively impaired was 65 %] where it was possible to compare abridged MMSE scales to dementia diagnoses and to the full MMSE scale. We estimated the sensitivity and specificity levels of the abridged tests, using clinical diagnoses as reference. Analyses with both the HARMONY and the ADAMS data indicated comparable levels of sensitivity and specificity in detecting cognitive impairment for the two abridged scales relative to the full MMSE. Receiver operating characteristic curves indicated that the two abridged scales corresponded well to those of the full MMSE. The two abridged tests have adequate validity and correspond well with the full MMSE. The abridged versions could therefore be alternatives to consider in larger population studies where interview length is restricted, and the respondent burden is high. [ABSTRACT FROM AUTHOR]

Purpose of Study: Dementia affects more than 5 million Americans, and is a leading cause of death. Family members of nursing home (NH) residents with advanced dementia report difficulty making decisions about care toward the end of life. As part of a randomized trial testing an intervention to improve decision making, this qualitative study aimed to understand how family decision makers experienced goal-based decision making in advance of the death of their relative. Design and Methods: This qualitative study was conducted as part of the goals of care clinical trial. Study participants ( n = 16) were family decision makers in North Carolina whose relative with advanced dementia died after participating in the goals of care intervention. Semi-structured interviews were analyzed using a qualitative description approach. Results: Family members' experience of decision making and death differed based on the presence or absence of trusting relationships with NH staff. Family members who reported trust described a positive end-of-life experience and less need for prescribed goals of care discussions. In the absence of trust, family members reported that goals of care discussions were ignored by staff or created confusion. Implications: Among family members of persons who recently died from dementia in NHs, expressions of trust in staff were strongly related to perceptions of decision making about goals of care. Although goals of care discussions may potentially promote communication to earn trust, the presence of pre-existing trust ultimately influenced the decision making and end-of-life experiences of residents and families.

Objectives There is limited research in cognition and its relationship to mortality after hip fracture among men compared to women. Therefore, the goals of this study were to: (1) compare men and women who fractured their hip on cognition after hospital discharge, and (2) examine the impact of cognition on the differential risk of 6-month mortality between men and women post fracture. Design Prospective cohort study. Setting Eight hospitals in Baltimore, Maryland. Participants Frequency matched 168 male and 171 female hip fracture patients, ages 65 or older, living in the community before fracture. Measurements Cognition assed by Modified Mini-Mental State Examination (3 MS, and derived MMSE score), Hooper Visual Organization test ( HVOT), and Trail-making test (Trails A & B) within 22 days of hospital admission, and 6-month mortality. Results Men had more impaired cognitive scores on 3 MS, MMSE, HVOT, and Trails A ( P < .05) at baseline. These statistically significant differences between men and women remained on MMSE and HVOT after controlling for pre-fracture dementia, in-hospital delirium, age, education, race, and comorbidity. Men had higher 6-month mortality rates ( HR = 4.4, P < .001). Cognitive measures were also significantly associated with mortality, including 3 MS, HVOT, and Trails B. Among the cognitive measures, higher 3 MS was most protective for mortality ( HR = 0.98, P < .001), both unadjusted and adjusted for other cognitive scales, comorbidity, delirium, and pre-existing dementia. The highest mortality was among men with 3 MS<78, with 26.3% dying within 6 months. The effects of cognition on mortality did not differ by sex. Conclusion Men display greater levels of cognitive impairment within the first 22 days of hip fracture than women, and cognitive limitations increase the risk of mortality in both men and women.

Objectives To examine factors associated with isolation precaution use in nursing home ( NH) residents with multidrug-resistant organism ( MDRO) infection. Design Retrospective, cross-sectional analysis. Setting Nursing homes with Centers for Medicare and Medicaid Services' certification from October 2010 to December 2013. Participants Elderly, long-stay NH residents with positive MDRO infection assessments. Measurements Data were obtained from the Minimum Data Set ( MDS) 3.0, Certification and Survey Provider Enhanced Reporting, and Area Health Resource File. Multivariable regression with facility fixed effects was conducted. Results The sample included 191,816 assessments of residents with MDRO infection, of which isolation use was recorded in 12.8%. Of the NHs reporting MDRO infection in the past year, 31% used isolation at least once among residents with MDRO infection. Resident characteristics positively associated with isolation use included locomotion (23.6%, P < .001) and eating (17.9%, P < .001) support. Isolation use was 14.3% lower in those with MDRO history ( P < .001). Residents in NHs that had received an infection control-related citation in the past year had a greater probability of isolation use (3.4%, P = .02); those in NHs that had received a quality-of-care citation had lower probability of isolation use (−3.3%, P = .03). Conclusion This is the first study to examine the new MDS 3.0 isolation and MDRO items. Isolation was infrequently used, and the proportion of isolated MDRO infections varied between facilities. Inspection citations were related to isolation use in the following year. Further research is needed to determine whether and when isolation should be used to best decrease risk of MDRO transmission and improve quality of care. [ABSTRACT FROM AUTHOR]

Purpose: Approximately 27 million adults are living with undiagnosed dementia worldwide. The purpose of this study was to learn about the experiences of adult children of elderly parents who were ultimately diagnosed with dementia. Data sources: A descriptive qualitative design was used for identifying if there were prodromal signs or symptoms that preceded the more commonly known warning signs of dementia. Twelve, 60-min interviews were conducted over the telephone. Conclusions: The overarching theme was: "Why didn't I know?" Subthemes were "We ignored it because we didn't want it to be," "We thought it was grief," and "They wouldn't diagnose dementia." Normal aging changes often mask the identification of mild cognitive impairment (MCI) and dementia. Healthcare providers should screen patients for dementia when cognitive concerns or changes become apparent. Implications for practice: The General Practitioner Assessment of Cognition and the Mini-Cog can be used for screening cognitive changes. Since depression may be misinterpreted as dementia, screening for depression should also be included if there is a potential for overlap. This is important in those patients who are experiencing grief, as many signs and symptoms of early grief are the same as early dementia. [ABSTRACT FROM AUTHOR]

Objectives To describe the effect of dementia on hospital outcomes of individuals requiring invasive mechanical ventilation ( IMV). Design Retrospective cohort study. Setting 2011 Nationwide Inpatient Sample. Participants Hospitalized individuals with and without dementia undergoing IMV. Measurements The adjusted predicted probability of undergoing IMV was examined in individuals with and without dementia. Then the dataset was limited to individuals who received IMV, and a multivariable logistic regression model was created in which dementia was the primary predictor and mortality was the outcome. Results Of the 13,816,586 hospitalizations of older adults in the United States in 2011, 2,204,506 (16%) with a dementia diagnosis code were identified. Individuals with dementia had statistically significantly lower predicted probability of undergoing IMV (5.7%, 95% confidence interval ( CI) = 5.6-5.8% than those without (6.5%, 95% CI = 6.4-6.6%). When the dataset was limited to individuals undergoing IMV, those with dementia were older (mean age 80 vs 76, P < .001) and had a higher combined Gagne comorbidity score (4.4 vs 4.1, P < .001) than those without. In a multivariable model, dementia was associated with greater likelihood of survival to hospital discharge (odds ratio ( OR) = 0.79, P < .001). Individuals with dementia also had shorter mean length of stay (12.5 ± 0.2 vs 13.1 ± 0.2, P = .01) and lower cost per hospitalization for survivors ($37,213 vs $44,557, P < .001). Conclusion Older critically ill adults with dementia undergoing IMV had better in-hospital outcomes than those without dementia. Because a lower adjusted percentage of individuals with dementia underwent IMV, it is likely that patient selection drove outcome differences. These findings suggest that individuals, families, and clinicians are carefully considering prognosis, quality of life, and appropriate use of intensive care unit resources when deciding whether to use IMV in individuals with dementia.

Objectives To examine the prevalence of dementia in the absence of a reported dementia diagnosis and whether potentially unsafe activities and living conditions vary as a function of dementia diagnosis status in a nationally representative sample of older adults. Design Observational cohort study. Setting Community. Participants Medicare beneficiaries aged 65 and older enrolled in the National Health and Aging Trends Study (N = 7,609). Measurements Participants were classified into four groups based on self-report of dementia diagnosis, proxy screening interview, and cognitive testing: probable dementia with reported dementia diagnosis (n = 457), probable dementia without reported dementia diagnosis (n = 581), possible dementia (n = 996), or no dementia (n = 5,575). Potentially unsafe activities (driving, preparing hot meals, managing finances or medications, attending doctor visits alone) and living conditions (falls, living alone, and unmet needs) were examined according to dementia status subgroups in stratified analyses and multivariate models, adjusting for sociodemographic factors, medical comorbidities, and physical capacity. Results The prevalence of driving (22.9%), preparing hot meals (31.0%), managing finances (21.9%), managing medications (36.6%), and attending doctor visits alone (20.6%) was lowest in persons with probable dementia; however, but in persons with probable dementia, the covariate-adjusted rates of driving, preparing hot meals, managing finances, managing medications, and attending doctor visits alone were significantly higher in those without reported dementia diagnosis than in those with reported diagnosis (all odds ratios ≥2.00, all P < .01). Conclusion Older adults with probable dementia who are not aware of a dementia diagnosis are more likely to report engaging in potentially unsafe behaviors. Understanding the prevalence of potentially unsafe activities and living conditions can help clinicians focus safety screening and counseling in older adults with diagnosed or suspected dementia.

As the population of the United States ages, the rates of dementia are also likely to increase. Clinicians will, therefore, likely be asked to evaluate and treat an escalating number of patients experiencing a decline in multiple domains of cognitive function, which is the hallmark of neurocognitive disorders. It is also probable that clinicians will be confronted with management dilemmas related to the myriad of psychological and behavioral problems that often occur as a consequence of the neurocognitive impairment. In fact, these behavioral and psychological issues might be the initial symptoms that lead the patient to present to the clinician. Dementia has multiple potential etiologies, and a careful diagnostic assessment is imperative to best characterize the specific type of dementia impacting the patient. This is important, as knowing the type of dementia helps the clinician choose the most effective treatment. Potential treatments should be interdisciplinary in scope, patient/family-centered, and may include both nonpharmacologic and pharmacologic treatments. [ABSTRACT FROM AUTHOR]
