The Effect of Physical and Cognitive Impairments on Caregiving

2024 Alzheimer's disease facts and figures

This article describes the public health impact of Alzheimer's disease (AD), including prevalence and incidence, mortality and morbidity, use and costs of care and the ramifications of AD for family caregivers, the dementia workforce and society. The Special Report discusses the larger health care system for older adults with cognitive issues, focusing on the role of caregivers and non-physician health care professionals. An estimated 6.9 million Americans age 65 and older are living with Alzheimer's dementia today. This number could grow to 13.8 million by 2060, barring the development of medical breakthroughs to prevent or cure AD. Official AD death certificates recorded 119,399 deaths from AD in 2021. In 2020 and 2021, when COVID-19 entered the ranks of the top ten causes of death, Alzheimer's was the seventh-leading cause of death in the United States. Official counts for more recent years are still being compiled. Alzheimer's remains the fifth-leading cause of death among Americans age 65 and older. Between 2000 and 2021, deaths from stroke, heart disease and HIV decreased, whereas reported deaths from AD increased more than 140%. More than 11 million family members and other unpaid caregivers provided an estimated 18.4 billion hours of care to people with Alzheimer's or other dementias in 2023. These figures reflect a decline in the number of caregivers compared with a decade earlier, as well as an increase in the amount of care provided by each remaining caregiver. Unpaid dementia caregiving was valued at $346.6 billion in 2023. Its costs, however, extend to unpaid caregivers' increased risk for emotional distress and negative mental and physical health outcomes. Members of the paid health care and broader community-based workforce are involved in diagnosing, treating and caring for people with dementia. However, the United States faces growing shortages across different segments of the dementia care workforce due to a combination of factors, including the absolute increase in the number of people living with dementia. Therefore, targeted programs and care delivery models will be needed to attract, better train and effectively deploy health care and community-based workers to provide dementia care. Average per-person Medicare payments for services to beneficiaries age 65 and older with AD or other dementias are almost three times as great as payments for beneficiaries without these conditions, and Medicaid payments are more than 22 times as great. Total payments in 2024 for health care, long-term care and hospice services for people age 65 and older with dementia are estimated to be $360 billion. The Special Report investigates how caregivers of older adults with cognitive issues interact with the health care system and examines the role non-physician health care professionals play in facilitating clinical care and access to community-based services and supports. It includes surveys of caregivers and health care workers, focusing on their experiences, challenges, awareness and perceptions of dementia care navigation.

A Pressure Release Valve: South Korean Long-Term Care Policy as Supplemental to Family Elder Care

South Korea's National Long-term Care Insurance (NLTCI) has received international acclaim for its universal continuum-of-care model. Based on 25 qualitative interviews with family caregivers, this research explores the relationship between NLTCI policies and experiences of family caregiving for older people. Caregivers who share care responsibilities or are supported by other family are coping well with minor to moderate policy recommendations. Lone caregivers without support from other family are struggling and express desire for expanded services. These findings highlight a need for more consideration of the influence of family dynamics on informal caregiver burdens. Despite many strengths, NLTCI policy functions as a pressure release valve, supplementing family care for seniors - not replacing it - with minimal gender equity contributions.

Racial-Ethnic Disparities in Dual-Function Life Expectancy

BACKGROUND

This study develops a new concept, dual functionality, that integrates physical and cognitive function. We use the concept to define a measure of dual-function life expectancy (2FLE) and assess racial-ethnic inequalities in aging.

METHODS

Drawing on data from the National Health Interview Survey Linked Mortality Files and the Health and Retirement Study, we define dual functionality as having no limitations in activities of daily living and being free of dementia. We use this measure and Sullivan life tables to estimate age-50 total life expectancy and age-50 2FLE for women and men across 4 racial-ethnic and nativity groups.

RESULTS

At ages 50-54, between 79.0% (95% CI: 73.5, 84.5) and 87.6% (95% CI: 84.0, 91.2) of (non-Hispanic) Black, foreign-born Hispanic, and U.S.-born Hispanic women and men remain dual functional as compared with 90.4% (95% CI: 89.3, 91.4) and 91.4% (95% CI: 90.2, 92.5) of (non-Hispanic) White women and men, respectively. These and corresponding racial-ethnic disparities in dual functionality through ages 85 and older translate into substantial inequalities in 2FLE. For instance, the Black-White gap in age-50 2FLE is 6.9 years (95% CI: -7.5, -6.4) for women and 6.0 years (95% CI: -6.6, -5.4) for men.

CONCLUSIONS

Black, foreign-born Hispanic, and U.S.-born Hispanic older adults are estimated to live a smaller percentage of their remaining years with dual functionality than White older adults. These results reveal stark racial-ethnic inequalities in aging that have significant implications for quality of life, caregiving, and health needs.

The Effects of Increasing State Minimum Wage on Family and Paid Caregiving

Older adults may receive either or a combination of unpaid family/friend and paid caregiving. The consumption of family/friend and paid caregiving may be sensitive to minimum wage policies. We used data (n = 11,698 unique respondents) from the Health and Retirement Study and a difference-in-differences design to evaluate associations between increases in state minimum wage between 2010 and 2014 and family/friend and paid caregiving consumed by adults age 65+ years. We also examined responses to increases in minimum wage for respondents with dementia or Medicaid beneficiaries. People living in states that increased their minimum wage did not consume substantially different hours of family/friend, paid, or any family/friend or paid caregiving. We did not observe differential responses between increases in minimum wage and hours of family/friend or paid caregiving among people with dementia or Medicaid beneficiaries. Increases in state minimum wage were not associated with changes in caregiving consumed by adults age 65+.

2023 Alzheimer's disease facts and figures

This article describes the public health impact of Alzheimer's disease, including prevalence and incidence, mortality and morbidity, use and costs of care, and the overall impact on family caregivers, the dementia workforce and society. The Special Report examines the patient journey from awareness of cognitive changes to potential treatment with drugs that change the underlying biology of Alzheimer's. An estimated 6.7 million Americans age 65 and older are living with Alzheimer's dementia today. This number could grow to 13.8 million by 2060 barring the development of medical breakthroughs to prevent, slow or cure AD. Official death certificates recorded 121,499 deaths from AD in 2019, and Alzheimer's disease was officially listed as the sixth-leading cause of death in the United States. In 2020 and 2021, when COVID-19 entered the ranks of the top ten causes of death, Alzheimer's was the seventh-leading cause of death. Alzheimer's remains the fifth-leading cause of death among Americans age 65 and older. Between 2000 and 2019, deaths from stroke, heart disease and HIV decreased, whereas reported deaths from AD increased more than 145%. This trajectory of deaths from AD was likely exacerbated by the COVID-19 pandemic in 2020 and 2021. More than 11 million family members and other unpaid caregivers provided an estimated 18 billion hours of care to people with Alzheimer's or other dementias in 2022. These figures reflect a decline in the number of caregivers compared with a decade earlier, as well as an increase in the amount of care provided by each remaining caregiver. Unpaid dementia caregiving was valued at $339.5 billion in 2022. Its costs, however, extend to family caregivers' increased risk for emotional distress and negative mental and physical health outcomes - costs that have been aggravated by COVID-19. Members of the paid health care workforce are involved in diagnosing, treating and caring for people with dementia. In recent years, however, a shortage of such workers has developed in the United States. This shortage - brought about, in part, by COVID-19 - has occurred at a time when more members of the dementia care workforce are needed. Therefore, programs will be needed to attract workers and better train health care teams. Average per-person Medicare payments for services to beneficiaries age 65 and older with AD or other dementias are almost three times as great as payments for beneficiaries without these conditions, and Medicaid payments are more than 22 times as great. Total payments in 2023 for health care, long-term care and hospice services for people age 65 and older with dementia are estimated to be $345 billion. The Special Report examines whether there will be sufficient numbers of physician specialists to provide Alzheimer's care and treatment now that two drugs are available that change the underlying biology of Alzheimer's disease.

Profiles of Caregiving Arrangements of Community-dwelling People Living with Probable Dementia

People living with dementia receive care from multiple caregivers, but little is known about the structure of their caregiving arrangements. This study used the Health and Retirement Study and latent class analyses to identify subgroups of caregiving arrangements based on caregiving hours received from spouses, children, other family/friends, and paid individuals among married (n = 361) and unmarried (n = 473) community-dwelling people with probable dementia. Three classes in the married sample (class 1 "low hours with shared care," class 2 "spouse-dominant care," and class 3 "children-dominant care") were identified. In class 1, spouses, children, and paid individuals provided 53%, 22%, and 26% of the caregiving hours, respectively. Three classes in the unmarried sample (class 1 "low hours with shared care," class 2 "children-dominant care," and class 3 "paid-dominant care") were identified. In unmarried class 1, children, other family/friends, and paid individuals provided 35%, 41% and 24% of the caregiving hours, respectively.

Prevalence of Alzheimer's disease and related dementias among veterans experiencing housing insecurity

INTRODUCTION

Housing insecure veterans are aging, but the prevalence of Alzheimer's disease and related dementias (AD/ADRD) in the population is unknown.

METHODS

We calculated the prevalence of AD/ADRD diagnoses in 2018 among veterans that experienced homelessness, were at-risk for homelessness, or were stably housed. We determined acute care (emergency department, hospitalizations, psychiatric hospitalizations), and any long-term care (nursing home, and community-based) use by housing status among veterans with an AD/ADRD diagnosis.

RESULTS

The overall prevalence of AD/ADRD diagnoses for homeless, at-risk, and stably housed veterans was 3.66%, 13.48%, and 3.04%, respectively. Housing insecure veterans with AD/ADRD used more acute care, and were more likely to have a nursing home admission compared to stably housed veterans. At risk, but not homeless veterans, were more likely to use US Department of Veterans Affairs-paid home and community-based care than stably housed veterans.

DISCUSSION

The prevalence of AD/ADRD diagnoses is greater among housing insecure veterans than stably housed veterans.

2022 Alzheimer's disease facts and figures

This article describes the public health impact of Alzheimer's disease (AD), including incidence and prevalence, mortality and morbidity, use and costs of care, and the overall impact on family caregivers, the dementia workforce and society. The Special Report discusses consumers' and primary care physicians' perspectives on awareness, diagnosis and treatment of mild cognitive impairment (MCI), including MCI due to Alzheimer's disease. An estimated 6.5 million Americans age 65 and older are living with Alzheimer's dementia today. This number could grow to 13.8 million by 2060 barring the development of medical breakthroughs to prevent, slow or cure AD. Official death certificates recorded 121,499 deaths from AD in 2019, the latest year for which data are available. Alzheimer's disease was officially listed as the sixth-leading cause of death in the United States in 2019 and the seventh-leading cause of death in 2020 and 2021, when COVID-19 entered the ranks of the top ten causes of death. Alzheimer's remains the fifth-leading cause of death among Americans age 65 and older. Between 2000 and 2019, deaths from stroke, heart disease and HIV decreased, whereas reported deaths from AD increased more than 145%. More than 11 million family members and other unpaid caregivers provided an estimated 16 billion hours of care to people with Alzheimer's or other dementias in 2021. These figures reflect a decline in the number of caregivers compared with a decade earlier, as well as an increase in the amount of care provided by each remaining caregiver. Unpaid dementia caregiving was valued at $271.6 billion in 2021. Its costs, however, extend to family caregivers' increased risk for emotional distress and negative mental and physical health outcomes - costs that have been aggravated by COVID-19. Members of the dementia care workforce have also been affected by COVID-19. As essential care workers, some have opted to change jobs to protect their own health and the health of their families. However, this occurs at a time when more members of the dementia care workforce are needed. Average per-person Medicare payments for services to beneficiaries age 65 and older with AD or other dementias are almost three times as great as payments for beneficiaries without these conditions, and Medicaid payments are more than 22 times as great. Total payments in 2022 for health care, long-term care and hospice services for people age 65 and older with dementia are estimated to be $321 billion. A recent survey commissioned by the Alzheimer's Association revealed several barriers to consumers' understanding of MCI. The survey showed low awareness of MCI among Americans, a reluctance among Americans to see their doctor after noticing MCI symptoms, and persistent challenges for primary care physicians in diagnosing MCI. Survey results indicate the need to improve MCI awareness and diagnosis, especially in underserved communities, and to encourage greater participation in MCI-related clinical trials.

Prevalence and severity of cognitive dysfunction in patients referred for transcatheter aortic valve implantation (TAVI): clinical and cognitive impact at 1 year

AIM

We estimated the proportion and severity of cognitive disorders in an unselected population of patients referred for transcatheter aortic valve implantation (TAVI). Second, we describe clinical and cognitive outcomes at 1 year.

METHODS

Eligible patients were aged ≥ 70 years, with symptomatic aortic stenosis and an indication for TAVI. The Montreal Cognitive Assessment (MoCA) was used to assess cognitive dysfunction (CD), defined as no CD if score ≥ 26, mild CD if 18-25; moderate CD if 10-18, and severe CD if < 10. We assessed survival and in-hospital complications at 6 months and 1 year.

RESULTS

Between June 2019 and October 2020, 105 patients were included; 21 (20%) did not undergo TAVI, and thus, 84 were analyzed; median age 85 years, 53.6% females, median EuroScore 11.5%. Median MoCA score was 22 (19-25); CD was excluded in 18 (21%), mild in 50 (59.5%), moderate in 15 (19%) and severe in 1. Mean MoCA score at follow-up was 21.9(± 4.69) and did not differ significantly from baseline (21.79 (± 4.61), p = 0.73). There was no difference in success rate, in-hospital complications, or death across CD categories.

CONCLUSION

The clinical course of patients with mild or moderate CD is not different at 1 year after TAVI compared to those without cognitive dysfunction.

Incident Care Trajectories for Older Adults with and without Dementia

OBJECTIVE

Despite cross-sectional evidence that persons living with dementia receive disproportionate hours of care, studies of how care intensity progresses over time and differs for those living with and without dementia have been lacking.

METHODS

We used the 2011-2018 National Health and Aging Trends Study to estimate growth mixture models to identify incident care hour trajectories ("classes") among older adults (N=1,780).

RESULTS

We identified four incident care hour classes: "Low, stable," "High, increasing," "24/7 then high, stable," and "Low then resolved." The high-intensity classes had the highest proportions of care recipients with dementia and accounted for nearly half of that group. Older adults with dementia were 3-4 times as likely as other older adults to experience one of the two high-intensity trajectories. A substantial proportion of the 4 in 10 older adults with dementia who were predicted to be in the "Low, stable" class lived in residential care settings.

DISCUSSION

Information on how family caregiving is likely to evolve over time in terms of care hours may help older adults with and without dementia, the family members, friends, and paid individuals who care for them, as well as their health care providers assess and plan for future care needs.

A longitudinal evaluation of family caregivers' willingness to pay for an in-home nonpharmacologic intervention for people living with dementia: results from a randomized trial

OBJECTIVE

To determine the willingness-to-pay (WTP) of family caregivers to learn care strategies for persons living with dementia (PLwD).

DESIGN

Randomized clinical trial.

SETTING

Community-dwelling PLwD and their caregivers (dyads) in Maryland and Washington, DC.

PARTICIPANTS

250 dyads.

INTERVENTION

Tailored Activity Program (TAP) compared to attention control. TAP provides activities tailored to the PLwD and instructs caregivers in their use.

MEASUREMENT

At baseline, 3 and 6 months, caregivers were asked their WTP per session for an 8-session 3-month in-home nonpharmacologic intervention to address behavioral symptoms and functional dependence.

RESULTS

At baseline, 3 and 6 months, caregivers assigned to TAP were willing to pay $26.10/session (95%CI:$20.42, $33.00), $28.70 (95%CI:$19.73, $39.30), and $22.79 (95%CI: $16.64, $30.09), respectively; attention control caregivers were willing to pay $37.90/session (95%CI: $27.10, $52.02), $30.92 (95%CI: $23.44, $40.94), $27.44 (95%CI: $20.82, $35.34), respectively. The difference in baseline to 3 and 6 months change in WTP between TAP and the attention control was $9.58 (95%CI: -$5.00, $25.47) and $7.15 (95%CI: -$5.72, $21.81). The difference between TAP and attention control in change in the proportion of caregivers willing to pay something from baseline to 3 and 6 months was -12% (95%CI: -28%, -5%) and -7% (95%CI:-25%, -11%), respectively. The difference in change in WTP, among caregivers willing to pay something, between TAP and attention control from baseline to 3 and 6 months was $17.93 (95%CI: $0.22, $38.30) and $11.81 (95%CI: -$2.57, $28.17).

CONCLUSIONS

Family caregivers are willing to pay more for an intervention immediately following participation in a program similar to which they were asked to value.

2021 Alzheimer's disease facts and figures

This article describes the public health impact of Alzheimer's disease (AD), including incidence and prevalence, mortality and morbidity, use and costs of care, and the overall impact on caregivers and society. The Special Report discusses the challenges of providing equitable health care for people with dementia in the United States. An estimated 6.2 million Americans age 65 and older are living with Alzheimer's dementia today. This number could grow to 13.8 million by 2060 barring the development of medical breakthroughs to prevent, slow or cure AD. Official death certificates recorded 121,499 deaths from AD in 2019, the latest year for which data are available, making Alzheimer's the sixth-leading cause of death in the United States and the fifth-leading cause of death among Americans age 65 and older. Between 2000 and 2019, deaths from stroke, heart disease and HIV decreased, whereas reported deaths from AD increased more than 145%. This trajectory of deaths from AD was likely exacerbated in 2020 by the COVID-19 pandemic. More than 11 million family members and other unpaid caregivers provided an estimated 15.3 billion hours of care to people with Alzheimer's or other dementias in 2020. These figures reflect a decline in the number of caregivers compared with a decade earlier, as well as an increase in the amount of care provided by each remaining caregiver. Unpaid dementia caregiving was valued at $256.7 billion in 2020. Its costs, however, extend to family caregivers' increased risk for emotional distress and negative mental and physical health outcomes - costs that have been aggravated by COVID-19. Average per-person Medicare payments for services to beneficiaries age 65 and older with AD or other dementias are more than three times as great as payments for beneficiaries without these conditions, and Medicaid payments are more than 23 times as great. Total payments in 2021 for health care, long-term care and hospice services for people age 65 and older with dementia are estimated to be $355 billion. Despite years of efforts to make health care more equitable in the United States, racial and ethnic disparities remain - both in terms of health disparities, which involve differences in the burden of illness, and health care disparities, which involve differences in the ability to use health care services. Blacks, Hispanics, Asian Americans and Native Americans continue to have a higher burden of illness and lower access to health care compared with Whites. Such disparities, which have become more apparent during COVID-19, extend to dementia care. Surveys commissioned by the Alzheimer's Association recently shed new light on the role of discrimination in dementia care, the varying levels of trust between racial and ethnic groups in medical research, and the differences between groups in their levels of concern about and awareness of Alzheimer's disease. These findings emphasize the need to increase racial and ethnic diversity in both the dementia care workforce and in Alzheimer's clinical trials.

Assessment of Rural-Urban Differences in Health Care Use and Survival Among Medicare Beneficiaries With Alzheimer Disease and Related Dementia

IMPORTANCE

There is poor understanding as to how survival and health care use varies among older adults living with Alzheimer disease and related dementia (ADRD) in rural vs urban areas of the United States.

OBJECTIVE

To describe survival and trajectories of hospital, hospice, nursing home, and home health care use among rural and urban Medicare beneficiaries with ADRD in the 6 years after diagnosis.

DESIGN, SETTING, AND PARTICIPANTS

This retrospective cohort study linked Medicare claims data from January 1, 2009, to December 31, 2016, with nursing home and home health assessment data from all US counties. A total of 555 333 Medicare fee-for-service beneficiaries newly diagnosed with ADRD in 2010 were included. A total of 424 561 individuals (76.5%) resided in metropolitan counties, 75 001 (13.5%) in micropolitan counties, and 55 771 (10.0%) in rural counties.

EXPOSURES

Rurality of beneficiary's county of residence.

MAIN OUTCOMES AND MEASURES

Number of days survived after initial ADRD diagnosis; percent of survived days per month spent in the hospital, hospice nursing home, community with home health care services, and community without home health care services.

RESULTS

A total of 555 333 Medicare beneficiaries (mean [SD] age, 82.0 [7.5] years; 345 294 women [62.2%]; 480 286 White [86.5%]) were evaluated. Compared with metropolitan county residents, rural beneficiaries were younger (mean [SD] age, 81.6 [7.6] vs 82.1 [7.5] years), were less likely to be women (34 100 [61.1%] vs 264 688 [62.3%]), were more likely to be White (50 886 [91.2%] vs 361 205 [85.1%]) and Medicaid-eligible (14 264 [25.6%] vs 71 656 [16.9%]), and had fewer preexisting chronic conditions (mean [SD], 6.9 [2.8] vs 7.4 [2.9]). Medicare beneficiaries residing in metropolitan counties survived a mean (SD) of 1183.5 (826.0) days after diagnosis. Adjusting for individual demographic and clinical characteristics, rural and micropolitan county residents survived approximately 1.5 months less than metropolitan residents. The adjusted share of survived days spent in nursing homes was 5.7 (95% CI, 4.0-7.5) percentage points higher for rural vs metropolitan residents. The adjusted share of days in hospitals was 0.7 (95% CI, -0.9 to -0.4) percentage points lower, and the share of days in community without home health care was 4.6 (95% CI, -6.1 to -3.1) percentage points lower for rural vs metropolitan county residents. There were no statistically significant differences in home health or hospice use. Similar patterns were found for micropolitan vs metropolitan residents as for rural vs metropolitan residents, although the magnitude of the differences were smaller. Differences in time spent in community and nursing homes between rural vs metropolitan beneficiaries became more pronounced with further time from diagnosis.

CONCLUSIONS AND RELEVANCE

Study results suggest that, after diagnosis, rural Medicare beneficiaries with ADRD spend more time in nursing homes and less time in the community, receive less home health care, and have shorter survival than their urban counterparts.
