Death of a Child Prior to Midlife, Dementia Risk, and Racial Disparities

OBJECTIVES

This study considers whether experiencing the death of a child prior to midlife (by parental age 40) is associated with subsequent dementia risk, and how such losses, which are more common for black than for white parents, may add to racial disparities in dementia risk.

METHODS

We use discrete-time event history models to predict dementia incidence among 9,276 non-Hispanic white and 2,182 non-Hispanic black respondents from the Health and Retirement Study, 2000-2014.

RESULTS

Losing a child prior to midlife is associated with increased risk for later dementia, and adds to disparities in dementia risk associated with race. The death of a child is associated with a number of biosocial variables that contribute to subsequent dementia risk, helping to explain how the death of child may increase risk over time.

DISCUSSION

The death of a child prior to midlife is a traumatic life course stressor with consequences that appear to increase dementia risk for both black and white parents, and this increased risk is explained by biosocial processes likely activated by bereavement. However, black parents are further disadvantaged in that they are more likely than white parents to experience the death of a child, and such losses add to the already substantial racial disadvantage in dementia risk.

Incremental Health Care Expenditures of the Spouses of Older Adults With Alzheimer's Diseases and Related Dementias (ADRD)

OBJECTIVE

Previous research has found that having a spouse with Alzheimer's disease and related dementias (ADRD) is associated with higher health care expenditures, however it is unclear if this difference remains after accounting for the demographics and health status of the non-ADRD spouse. This paper aims to estimate the adjusted incremental health care expenditures of having a spouse with ADRD.

DESIGN

Cross-sectional study of publicly available survey data (2003-2017 Medical Expenditure Panel Survey).

SETTING

Representative sample of U.S. households.

PARTICIPANTS

Community-dwelling and married older adults (n = 28,356).

MEASUREMENT

Two-part models and recycled prediction techniques to estimate the incremental effects of having a spouse with ADRD on annual health care expenditures, while adjusting for demographics, socioeconomic characteristics, and health conditions.

RESULTS

Spouses of older adults with ADRD were older, had worse perceived mental health, and had greater difficulties with activities of daily living, compared to older adults with cognitively normal spouses. Spouses of ADRD patients had significantly higher unadjusted total health care expenditures, however their adjusted incremental expenditure was not significantly greater. After controlling for demographics and health status, ADRD spouses had significantly higher home health care expenditures, but significantly lower outpatient expenditures.

CONCLUSION

Results suggested that the higher health care expenditures in older adults with ADRD spouses can be attributed to the higher rate of comorbidities, rate of functional limitations, and mean age in this group. The increased use of home health and decreased use of outpatient in this population suggests the importance of tailoring preventative health care and social services to meet the needs of this group.

Perceptions of couplehood among community-dwelling spousal caregivers

Objective: Spousal caregiving is increasingly common, and it is a role that can alter the nature of marriage in later life. Some may find spousal caregiving to be distressing, while others may have more positive experiences. Spousal caregiving, in particular, may be difficult due to caregiver burden as well as a loss of couplehood within the relationship. The current study used grounded theory methods to better understand the experience of and changes in couplehood among spousal caregivers.Method: Thirteen spousal caregivers completed semi-structured interviews. Spousal caregivers ranged in age from 53 to 85 (mean age = 66.00, SD = 9.04).Results: Qualitative analysis revealed four major themes upon evaluation of the interviews (couplehood, positive mindset, later life roles and transitions, and looking towards the future).Conclusion: These themes exemplified the complex interplay of couplehood and caregiving as well as the range of perceptions of couplehood. Results showed that while some caregivers struggle to find meaning and happiness within their caregiver role, and others said the illness/impairment bonded them together. Caregivers who reported a low sense couplehood discussed feeling trapped in their relationship, sad, and isolated. For some caregivers, a strong sense of couplehood may have helped them reframe the experience as an opportunity to be a role model for others and a reminder that their situation could be worse. Future research should focus on pre-illness couplehood and whether the nature of the impairment (e.g., cognitive, physical) is related to caregiver's couplehood.

Care Recipient Multimorbidity and Health Impacts on Informal Caregivers: A Systematic Review

BACKGROUND AND OBJECTIVES

Caregiving outcomes have often been reported in terms of care recipients of single disease, rather than multiple health conditions. A systematic review was conducted to outline caregiving health outcomes and its association with care recipient multimorbidity for informal caregivers of older adults.

RESEARCH DESIGN AND METHODS

A search strategy was applied in six databases and grey literature. Inclusion criteria were primary observational studies on informal caregiving for care recipients aged 60 years and above, in the English language. Informal caregivers were those not formally hired and multimorbidity referred to presence of at least two health conditions. From a total of 2,101 titles, 230 abstracts were screened, and 19 articles were included. Quality assessment was conducted with application of the Newcastle-Ottawa-Scale.

RESULTS

Health-related and caregiving-related outcomes have been assessed for informal caregivers of older adults with multimorbidity. Caregiver subjective burden was most commonly evaluated and often reported to be low to moderate. In association with care recipient multimorbidity, caregiver burden, quality of life, and perceived difficulty in assisting the older adults were examined in 14 of the studies with mixed results. Studies were heterogeneous, with nonuniform definitions of informal caregivers and multimorbidity as well as measurement tools.

DISCUSSION AND IMPLICATIONS

This narrative review found that caring for older adults with multimorbidity impacts caregivers, although overall evidence is not conclusive. Despite caregiving-related outcomes being most commonly assessed among the caregivers, particularly subjective burden, findings suggest that it is worthwhile to examine other outcomes to enrich the evidence base.

Experiences of oldest-old caregivers whose partner is approaching end-of-life: A mixed-method systematic review and narrative synthesis

Population ageing has rapidly increased the number of people requiring end-of-life care across the globe. Governments have responded by promoting end-of-life in the community. Partly as a consequence, older spouses are frequently providing for their partner's end-of-life care at home, despite potentially facing their own health issues. While there is an emerging literature on young-old caregivers, less is known about spouse carers over 75 who are likely to face specific challenges associated with their advanced age and relationship status. The aim of this review, therefore, is to identify and synthesise the literature concerning the experiences of caregiver's aged 75 and over whose partner is approaching end-of-life. We conducted a mixed-method systematic review and narrative synthesis of the empirical literature published between 1985 and May 2019, identified from six databases: Medline, PsychINFO, Cumulative Index to Nursing and Allied Health Literature, Embase, Sociological Abstracts and Social Service Abstracts. Hand searching and reference checking were also conducted. Gough's Weight of Evidence and Morgan's Feminist Quality Appraisal tool used to determine the quality of papers. From the initial 7819 titles, 10 qualitative studies and 9 quantitative studies were included. We identified three themes: 1) "Embodied impact of care" whereby caring was found to negatively impact carers physical and psychological health, with adverse effects continuing into bereavement; 2) "Caregiving spouse's conceptualisation of their role" in which caregiver's navigated their self and marriage identities in relation to their partner's condition and expectations about gender and place; 3) "Learning to care" which involved learning new skills and ways of coping to remain able to provide care. We identified a recent up-surge in published papers about very old spousal caregivers, which now comprise a small, medium-quality evidence base. This review outlines a range of potential lines of inquiry for future research including further clarification of the impact of caregiving on the likelihood of mortality, the incidence of men and women providing end-of-life care amongst this age group, and the role of anticipatory grief in shaping their perceptions of their relationship and their own longevity.

Comparison of cognitive performance and aspects of the care context in elderly caregivers in Brazil: A follow-up study

Cognitive health is important for the quality of life and well-being of elderly caregivers. Cognitive impairments can negatively affect the ability to care for oneself and others.

A Scoping Review of Literature on Sex and Gender Differences Among Dementia Spousal Caregivers

BACKGROUND AND OBJECTIVES

Sex and gender differences among dementia spousal caregivers have been investigated, but never systematically reviewed or synthesized. A synthesis of findings can help facilitate specificity in practice and in health policy development. As a first step towards such a synthesis, this scoping review reports the available evidence, identifies research gaps, and suggests possible directions for future research.

RESEARCH DESIGN AND METHODS

A scoping review methodology was used to identify articles, and to chart and analyze data. Systematic searches for published, empirical studies, with an explicit goal or hypothesis related to sex or gender differences were conducted in seven databases.

RESULTS

Sixty-one studies met inclusion criteria. Most (n = 45) were quantitative, cross-sectional studies. Caregivers included in the studies were generally 61-70 years old, Caucasian, middle-class, and highly educated. The most extensively investigated differences are: depression, burden, objective physical health, and informal supports.

DISCUSSION AND IMPLICATIONS

This scoping review is the first to summarize and critique the research on sex and gender differences that are specific to dementia spousal caregivers. The review can be used by researchers to make decisions regarding future systematic reviews and primary studies. To further strengthen the evidence base, future studies may benefit from including more caregivers of ethnic minorities, using more qualitative, longitudinal, or experimental designs, and focusing on variables needed to inform caregiving models and theories. Overall, this scoping review contributes to furthering gender-sensitive practices and policies that are better tailored to the specific needs of this population.

2020 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 future challenges of meeting care demands for the growing number of people living with Alzheimer's dementia in the United States with a particular emphasis on primary care. By mid-century, the number of Americans age 65 and older with Alzheimer's dementia may grow to 13.8 million. This represents a steep increase from the estimated 5.8 million Americans age 65 and older who have Alzheimer's dementia today. Official death certificates recorded 122,019 deaths from AD in 2018, 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 2018, deaths resulting from stroke, HIV and heart disease decreased, whereas reported deaths from Alzheimer's increased 146.2%. In 2019, more than 16 million family members and other unpaid caregivers provided an estimated 18.6 billion hours of care to people with Alzheimer's or other dementias. This care is valued at nearly $244 billion, but its costs extend to family caregivers' increased risk for emotional distress and negative mental and physical health outcomes. 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 2020 for health care, long-term care and hospice services for people age 65 and older with dementia are estimated to be $305 billion. As the population of Americans living with Alzheimer's dementia increases, the burden of caring for that population also increases. These challenges are exacerbated by a shortage of dementia care specialists, which places an increasing burden on primary care physicians (PCPs) to provide care for people living with dementia. Many PCPs feel underprepared and inadequately trained to handle dementia care responsibilities effectively. This report includes recommendations for maximizing quality care in the face of the shortage of specialists and training challenges in primary care.

Neuropsychological consequences of chronic stress: the case of informal caregivers

Introduction: Caring for a family member with a long-term illness is a significant source of chronic stress that might significantly accelerate the cognitive ageing of informal caregivers. Nevertheless, the absence of a defined theoretical body of literature on the neuropsychology of this population makes it difficult to understand what the characteristic neuropsychological deficits of these caregivers are.Aims: The main aim of this study is to carry out a systematic review of studies of cognitive deficits present in informal caregivers of people with several chronic pathologies, and analyse the effects of cognitive-behavioural interventions on caregivers' cognition.Methods: The scientific literature was reviewed following the PRISMA quality criteria for reviews using the following digital databases: PubMEd, PsycINFO, and Dialnet.Results: Identification of 2046 abstracts and retrieval of 211 full texts led to the inclusion of 38 papers. The studies showed heterogeneous results, but most of the cross-sectional studies reviewed that employed neuropsychological assessments concluded that informal caregivers reported a generalized cognitive deterioration, especially memory dysfunctions (i.e. learning verbal, visuospatial, and digit information). Moreover, they also presented low selective attention and capacity for inhibition, along with slow processing speed. Longitudinal studies confirmed that caregivers whose care situation was more prolonged showed a marked deterioration in their overall cognitive state, memory, processing speed, and vocabulary richness. However, although the patient's death does not seem to reverse the neuropsychological alterations in caregivers, cognitive-behavioural interventions that employ techniques to reduce stress levels, cognitive biases, and inadequate adaptation schemas seem to improve some of the aforementioned cognitive abilities.Conclusions: Results from this synthesis and critical analysis of neuropsychological deficits in informal caregivers offer guidelines for diagnosing caregivers' cognitive status by including a test battery covering all the domains considered relevant. Finally, given the ability of cognitive behavioural interventions to improve cognition in caregivers, further studies on their long-term effects on caregivers are warranted.Chronic stress entails an acceleration of the cognitive ageingCross-sectional studies concluded that informal caregivers reported a generalized cognitive deteriorationCognitive-behavioural interventions seem to improve cognitive abilities of caregivers.

Sex and Gender Driven Modifiers of Alzheimer's: The Role for Estrogenic Control Across Age, Race, Medical, and Lifestyle Risks

Research indicates that after advanced age, the major risk factor for late-onset Alzheimer’s disease (AD) is female sex. Out of every three AD patients, two are females with postmenopausal women contributing to over 60% of all those affected. Sex- and gender-related differences in AD have been widely researched and several emerging lines of evidence point to different vulnerabilities that contribute to dementia risk. Among those being considered, it is becoming widely accepted that gonadal steroids contribute to the gender disparity in AD, as evidenced by the “estrogen hypothesis.” This posits that sex hormones, 17β-estradiol in particular, exert a neuroprotective effect by shielding females’ brains from disease development. This theory is further supported by recent findings that the onset of menopause is associated with the emergence of AD-related brain changes in women in contrast to men of the same age. In this review, we discuss genetic, medical, societal, and lifestyle risk factors known to increase AD risk differently between the genders, with a focus on the role of hormonal changes, particularly declines in 17β-estradiol during the menopause transition (MT) as key underlying mechanisms.

The effect of psychosocial support on caregivers' perceived criticism and emotional over-involvement of persons with dementia: an assessor-blinded randomized controlled trial

BACKGROUND

Many relatives of close family members suffering from dementia have taken on the caregiver role. While intervention studies have revealed promising results on caregiver burden, distress, and depression, there is a lack of knowledge about how caregivers' perceived relationship with their ill family member influences the burden of care. This study examined whether a psychosocial intervention influenced this perceived relationship from the caregivers' perspective. We also explored whether the caregivers' perception of the care receiver's attitude and behavior changed over time, and whether caregiver stress and mood differed following the intervention.

METHODS

The participating caregivers and care receivers were randomly assigned to a psychosocial intervention comprising education about dementia, counselling and group sessions, or to treatment as usual. The study investigated caregivers' experience of expressed emotion using the Felt Expressed Emotion Rating Scale (FEERS), a self-report questionnaire that captures caregivers' perception of criticism (CC) and emotional over-involvement (EOI) exhibited by the family members with dementia.

RESULTS

A total of 208 dyads were enrolled in the study. There were no significant differences between the intervention and control groups in the studied variables. Caregivers' perception of CC and EOI was low but fluctuated somewhat, whereas their mood and stress level were stable during the follow-up period.

CONCLUSIONS

According to the FEERS, the intervention did not influence caregivers' perception of CC and EOI, and there was no difference between the intervention and control groups regarding caregivers' perceived relationship. Despite the increased symptoms of dementia, caregivers' level of distress and mood remained stable, and they seemed to maintain a positive perception of the quality of their relationship with the care receiver.

Being 'alone' striving for belonging and adaption in a new reality - The experiences of spouse carers of persons with dementia

BACKGROUND AND AIM

Spouse carers of a person with dementia report feeling lonely and trapped in their role, lacking support and having no time to take care of their own health. In Sweden, the support available for family carers is not specialised to meet the needs of spouse carers of people with dementia. The aim of the study described in this paper was to explore spouse carers' experiences of caring for a partner with dementia, their everyday life as a couple and their support needs.

METHODS

Nine spouse carers of a partner with dementia living at home were recruited through a memory clinic and a dementia organisation. Semi-structured interviews were conducted with the participants, focusing on their experiences of providing care, their support needs in relation to their caring situation, their personal well-being and their marital relationship. The interviews were transcribed and underwent qualitative content analysis.

RESULTS

The analysis resulted in one overall theme Being 'alone' striving for belonging and adaption in a new reality, synthesized from four sub-themes: (1) Being in an unknown country; (2) Longing for a place for me and us; (3) Being a carer first and a person second; and (4) Being alone in a relationship.

CONCLUSIONS

The training of care professionals regarding the unique needs of spouse carers of people with dementia needs improvement, with education, in particular, focusing on their need to be considered as a person separate from being a carer and on the significance of the couple's relationship for their mutual well-being.

Stress adaptation in older adults with and without cognitive impairment: an fMRI pattern-based similarity analysis

BACKGROUND

The capacity to adapt to environmental stressors is essential for older adults' health and well-being. It is unclear how cognitive impairment may disrupt the capacity. Here we examined the relationship between self-perceptions of stress and the neurobiological response to a laboratory model of stress adaptation in amnestic mild cognitive impairment (aMCI), a group at high risk for dementia.

RESULTS

aMCI group and cognitively healthy controls did not differ in neurobiological acute stress recovery (indexed by similarity in neural patterns at baseline and after recovery from cognitive challenges). However, compared to controls, aMCI group had significantly lower scores on PSS-PW. Notably, higher PSS-PW was associated with greater acute neural recovery in controls, but not aMCI.

METHODS

We assessed self-perceptions of stress adaptation with the Perceived Stress Scale subscales, measuring perceived helplessness (i.e., negatively worded items, PSS-NW) and self-efficacy (i.e., positively worded items, PSS-PW) in response to stress. At a subsequent laboratory fMRI visit, we indexed neurobiological stress adaptation by assessing and comparing functional network connectivity at baseline and immediately following, and after recovery from, cognitive challenges.

CONCLUSIONS

Studying stress adaptation in aMCI may shed light on pathways that contribute to the onset and progress of cognitive deterioration in aging.

Spousal Caregivers Are Caregiving Alone In The Last Years Of Life

Caregiving in the last years of life is associated with increased depression and negative health outcomes for surviving spouses, many of whom are themselves in poor health. Yet it is unclear how often spouses are caregiving alone, how they differ from supported spouses, and whether lack of support affects postbereavement outcomes. We hypothesized that spouses who were solo caregivers-that is, the only caregivers (paid or unpaid) who provided assistance with a spouse's self-care or household activities-would experience more depression after bereavement than supported spouses would. Using information from the Health and Retirement Study, we found that 55 percent of the spouses of community-dwelling married people with disability were solo caregivers. Solo caregiving was even common among people who cared for spouses with dementia and those with adult children living close by. Bereavement outcomes did not differ between solo and supported caregiving spouses. Caregiving spouses are often isolated and may benefit from greater support, particularly during the final years before bereavement. While some state and federal policy proposals aim to systematically recognize and assess caregivers, further innovations in care delivery and reimbursement are needed to adequately support seriously ill older adults and their caregivers. Ultimately, the focus of serious illness care must be expanded from the patient to the family unit.

Does Caregiving Strain Increase as Patients With and Without Dementia Approach the End of Life?

CONTEXT

Family caregivers play critical and demanding roles in the care of persons with dementia through the end of life.

OBJECTIVES

The objective of this study was to determine whether caregiving strain increases for dementia caregivers as older adults approach the end of life, and secondarily, whether this association differs for nondementia caregivers.

METHODS

Participants included a nationally representative sample of community-living older adults receiving help with self-care or indoor mobility and their primary caregivers (3422 dyads). Older adults' death within 12 months of survey was assessed from linked Medicare enrollment files. Multivariable logistic regression was used to assess the association between dementia and end-of-life status and a composite measure of caregiving strain (range: 0-9, using a cut point of 5 to define "high" strain) after comprehensively adjusting for other older adult and caregiver factors.

RESULTS

The prevalence of dementia in our sample was 30.1%; 13.2% of the sample died within 12 months. The proportion of caregivers who experienced high strain ranged from a low of 13.5% among nondementia, non-end-of-life caregivers to a high of 35.0% among dementia caregivers of older adults who died within 12 months. Among dementia caregivers, the odds of high caregiving strain were nearly twice as high (aOR = 1.94, 95% CI: 1.10-3.45) for those who were assisting older adults nearing end of life. Among nondementia caregivers, providing care near the end of life was not associated with high strain.

CONCLUSION

Increased strain toward the end of life is particularly notable for dementia caregivers. Interventions are needed to address the needs of this population.

Mental health in familial caregivers of Alzheimer's disease patients: are the effects of chronic stress on cognition inevitable?

Familial caregivers of Alzheimer's disease (AD) patients experience an emotional and physical burden which characterizes a chronic stress condition. The resulting hypothalamic-pituitary-adrenal axis dysfunction favors an imbalance of neurotoxic/neuroprotective factors and causes cognitive impairments, increasing the caregivers' risk for cognitive decline and compromising their ability to provide adequate care of the patient. Therefore, the present study aimed to investigate the reversibility of the cognitive impairments of familial caregivers of AD patients during their caregiving-related chronic stress condition. Thirty-three caregivers (61.42 + 2.68 years; 27 women) and thirty-four controls (57.91 ± 2.16 years, 20 women) were evaluated for their cognitive functioning (attention, executive function, processing speed and memory) with a neuropsychological battery (Digit-span, Trail Making, Stroop and the Logical Memory tests). Subjects' cortisol/dehydroepiandrosterone (DHEA) ratios were determined by radioimmunoassay, and their brain-derived neurotrophic factor (BDNF) levels were analyzed by ELISA. An incidental contextual memory task, with or without an associative encoding instruction, was used to investigate if caregivers have a cognitive reserve prone to rehabilitation. The contextual memory impairment of caregivers was associated with prefrontal and hippocampal cognitive dysfunctions, alterations of the cortisol/DHEA ratio and lower BDNF levels. Even so, the contextual memory impairment could be improved by the associative encoding condition. This study suggests that the cognitive impairments of caregivers are not necessarily irreversible, as indicated by the results obtained for contextual memory, which could be improved despite the ongoing chronic stress and associated hormonal and neurotrophin dysfunctions. Lay summary The support of a relative with Alzheimer's Disease submits the familial caregivers to a chronic stress condition that increases their own risk of cognitive decline. This study suggests that, irrespective to their alterations on cortisol/DHEA ratio and BDNF levels, caregivers have a cognitive reserve that could probably be engaged to limit the negative effects of chronic stress on cognition.

Development and validation of a screener based on interRAI assessments to measure informal caregiver wellbeing in the community

Background

Informal caregivers are invaluable partners of the health care system. However, their caring responsibilities often affect their psychological wellbeing and ability to continue in their role. It is of paramount importance to easily identify caregivers that would benefit from immediate assistance.

Methods

In this nonexperimental cohort study, a cross-sectional analysis was conducted among 362 informal caregivers (mean age 64.1 years, SD ± 13.1) caring for persons with high care needs (mean age 78.6 years, SD ± 15.0). Caregivers were interviewed using an interRAI-based self-reported survey with 82 items covering characteristics of caregivers including key aspects of wellbeing. A factor analysis identified items in the caregiver survey dealing with subjective wellbeing that were compared against other wellbeing measures. A screener, called Caregiver Wellbeing Index (CWBI), consisting of four items with response scores ranging from 0 to 2 was created. The CWBI was validated in a follow-up study in which 1020 screeners were completed by informal caregivers of home care clients. Clinical assessments of the care recipients (n = 262) and information on long-term care home (LTCH) admission (n = 176) were linked to the screener dataset. The association between the CWBI scores and caregiver and care recipient characteristics were assessed using logistic regression models and chi-square tests. The reliability of CWBI was also measured.

Results

The CWBI scores ranging from zero to eight were split in four ‘wellbeing’ levels (excellent, good, fair, poor). In the validation study, fair/poor psychological wellbeing was strongly associated with caregiver reports of inability to continue in their role; conflict with family; or feelings of distress, anger, or depression (P < 0.0001). Caregivers caring for a care recipient that presented changes in behavior, cognition, and mood were more likely to present fair/poor wellbeing (P < 0.0001). Additionally, caregivers with high CWBI scores (poor wellbeing) were also more likely to provide care for someone who was admitted to a LTCH (OR 3.52, CI 1.32–9.34) after controlling for care recipient and caregiver characteristics. The Cronbach alpha value 0.89 indicated high reliability.

Conclusion

The CWBI is a valid screener that can easily identify caregivers that might benefit from further assessment and interventions.

Resilience in family caregiving for people with dementia: A systematic review

OBJECTIVE

The objective of this review is to critically examine, evaluate, and synthesize the literature on resilience in family caregiving for people with dementia.

METHODS

A systematic literature review was conducted according to PRISMA guidelines to identify articles which examined resilience and related concepts in family caregiving for people with dementia. The review was based on a systematic search of scholarly databases, to yield peer-reviewed articles and grey literature, published between 2006 and 2016. Two independent reviewers prescreened the search results and conducted formal assessments and quality appraisals of the retrieved articles.

RESULTS

A total of 13 863 articles were identified by the systematic search, and 52 articles were included in the review. Based on a critical narrative synthesis of the literature, the study proposes a model of resilience for family carers of people with dementia, which incorporates the context of caring, social and cultural characteristics, and psychological dimensions of caring.

CONCLUSIONS

The results indicate that there is no single approach to enhancing resilience among family carers of people with dementia. Resilience is a multifaceted response to the caregiving role, and is influenced by a multitude of interrelated factors. However, the factors and resources outlined have been addressed, with limited success in some cases, by psychosocial interventions in the field. While the work conducted to date to develop resilience-enhancing interventions has been marked with some success, the next wave of carer research could usefully examine ecological perspectives on carer outcomes, including carer resilience.

Health and frailty among older spousal caregivers: an observational cohort study in Belgium

Background

Among older couples, spouses are first in line to provide care, and they are key elements in the home support of dependent older persons. In this context, ensuring the health of these older spousal caregivers should be an important issue for all of the providers who care for older adults. The aim of this study was to longitudinally assess the health of older spousal caregivers considering frailty, nutrition, cognition, physical performance and mood disorders.

Methods

In this longitudinal, observational cohort study, participants were assessed at home in Wallonia, Belgium. At baseline, 82 community-dwelling spouses of older patients with cognitive deficits or functional impairment were assessed; 78 caregivers were assessed at follow-up (16 months). The clinical instruments used included Frailty Phenotype (Fried), the Mini Nutritional Assessment-short form (MNA-SF), Short Physical Performance Battery (SPPB), Geriatric Depression Scale (GDS-15), clock drawing test, medications, Zarit Burden Index (ZBI), and Caregiver Reaction Assessment (CRA). Biological assessments included plasma interleukin-6 (IL-6), ultrasensitive C-reactive protein (CRP), cortisol, albumin and insulin growth factor-1 (IGF-1).

Results

Among caregivers, 54% were women, and the mean age was 80 years. Among care-receivers, 83% had cognitive impairment. Caregivers were more likely to be in a pre-frail stage. In one-third of the caregivers, the frailty status worsened. Transitions were observed between each of the states, except from frail to robust. In contrast to frailty, items including nutrition, cognitive status, SPPB and mood assessments were stable over time, with approximately 70% of the caregivers not experiencing significant change at follow-up. Caregiver experiences assessed with the Zarit Burden Interview and CRA were relatively stable over 16 months.

Conclusion

Many caregivers of geriatric patients are spouses who are old themselves. A failure in the health of the caregiver may anticipate an undesired care breakdown. Caregiver health and its determinants should be explored in future longitudinal studies that cover a longer time period.

Using Mobile Technology to Provide Personalized Reminiscence for People Living With Dementia and Their Carers: Appraisal of Outcomes From a Quasi-Experimental Study

BACKGROUND

Dementia is an international research priority. Reminiscence is an intervention that prompts memories and has been widely used as a therapeutic approach for people living with dementia. We developed a novel iPad app to support home-based personalized reminiscence. It is crucial that technology-enabled reminiscence interventions are appraised.

OBJECTIVE

We sought to measure the effect of technology-enabled reminiscence on mutuality (defined as the level of "closeness" between an adult living with dementia and their carer), quality of carer and patient relationship, and subjective well-being.

METHODS

A 19-week personalized reminiscence intervention facilitated by a program of training and a bespoke iPad app was delivered to people living with dementia and their family carers at their own homes. Participants (N=60) were recruited in dyads from a cognitive rehabilitation team affiliated with a large UK health care organization. Each dyad comprised a person living with early to moderate dementia and his or her family carer. Outcome measurement data were collected at baseline, midpoint, and intervention closure.

RESULTS

Participants living with dementia attained statistically significant increases in mutuality, quality of carer and patient relationship, and subjective well-being (P<.001 for all 3) from baseline to endpoint. Carers attained nonsignificant increases in mutuality and quality of carer and patient relationship and a nonsignificant decrease in subjective well-being.

CONCLUSIONS

Our results indicate that individual-specific reminiscence supported by an iPad app may be efficient in the context of early to moderate dementia. A robust randomized controlled trial of technology-enabled personalized reminiscence is warranted.

The impact of different types of informal caregiving on cognitive functioning of older caregivers: Evidence from a longitudinal, population-based study in Germany

STUDY AIM

This study's aim was to investigate the influence of different caregiving types on cognitive functioning of caregivers aged 65 years and older longitudinally and to look at potential gender differences in this association.

METHOD

Data from the German Ageing Survey, a longitudinal population-based study assessing community-dwelling people in Germany, was used. Our sample consisted of participants 65 years and older (waves 2008, 2011 and 2014; N = 6560). Informal caregiving was assessed in terms of three caregiving types (help around the house, looking after someone, performing nursing care services). An adaption of the widely used Digit Symbol Substitution Test was used to assess cognitive function.

RESULTS

Fixed-effects regressions demonstrated a positive association of looking after someone with cognitive functioning (β = 1.90, p < .01). There was no significant association of help around the house (β = 0.96, p = .22) or performing nursing care services (β = 2.12, p = .09) with cognitive function. Stratifying for gender, we found this effect of looking after someone on cognitive functioning only in women (β = 2.82, p < .01), but not in men (β = 1.00, p = .23). The other caregiving types showed no significant association with cognitive function, neither in men (helping around the house: β = 0.20, p = .85; performing nursing care services: β = 1.16, p = .52), nor in women (helping around the house: β = 1.67, p = .13; performing nursing care services: β = 2.88, p = .09).

CONCLUSIONS

Results indicate that informal caregiving, in terms of looking after someone, can be beneficial for cognitive function, at least for female caregivers. Thus, we recommend to consider caregiving types when investigating informal caregiving and cognitive function. Furthermore, we recommend to focus support more on other outcomes, particularly for female caregivers.

The assessment experience of spousal dementia care-givers: ‘It's made me realise that I am a person also’

This article is based on a study that used a validated care-giver assessment instrument known as ‘The C.A.R.E. (Caregivers’ Aspirations, Realities, and Expectations) Tool’ to understand its usefulness in working with older adults caring for a spouse with cognitive impairment. It draws on data collected as part of a larger, quasi-experimental pre- and post-test study examining the impact of a care-giver assessment on older spousal care-givers of a partner with cognitive impairment. One hundred community-living individuals (average age of 74) participated in the study. Participants met with a third-year nursing student who administered The C.A.R.E. Tool. Within three to seven days following this, a research team member conducted a semi-structured interview by telephone. This interview provided participants with the opportunity to comment on their experience and the usefulness of The C.A.R.E. Tool. Transcriptions of the interviews were analysed using a thematic analysis. Results indicate that the assessment experience was evaluated positively by most participants. Two broad themes emerged: assessment encourages care-givers to take stock of their situation, and it provides a relationship with a caring professional. In particular, the assessment experience gave these care-givers to have the opportunity to reflect, while expressing emotions and developing awareness, and provided them with an appreciated relationship with a caring professional who helped to validate and normalise their situation. For care-givers, the results suggest that assessment may serve as a catalyst for taking action in their care-giving situation or turning to services for help. For practitioners, assessment may increase awareness of the experience of spousal care-givers, potentially leading to interventions to support them. This study found that the attitudes and knowledge of practitioners play a role in care-givers’ experience of the assessment as positive. However, the goal of assessment must be clarified, as outcomes of other tools will differ depending on the aims.

[Resilience to mental disorders in old age]

BACKGROUND

Why does the aspect of aging justify a special survey of resilience to the development of mental disorders? Patterns of chronic stress burden change with age (e. g. disappearance of workplace-related stress, but increased risk of frequent chronic diseases). Moreover, capabilities and cognitive strategies of stress coping differ between young and older adults.

MATERIAL AND METHODS

The article summarizes relevant age aspects of resilience to mental disorders and evaluates the current knowledge concerning consecutive development of prevention strategies for avoidance of affective disorders and dementia.

RESULTS AND DISCUSSION

Stress-aggravating reduced cognitive functioning (especially executive problem solving) can be observed together with, probably stress-reducing, age-specific appraisal preferences (positivity effect) in older persons. Other age-specific aspects are resilience mechanisms against cognitive decline and dementia development despite cerebrovascular and neurodegenerative brain pathology-related conditions, which are referred to as cognitive reserve. Different cognitive reserve enhancing strategies can effectively contribute to dementia prevention.

A cross-sectional study of family caregiver burden and psychological distress linked to frailty and functional dependency of a relative with advanced dementia

Psychological health of caregivers of people with dementia is a major public concern. This study sought to determine the relationship between caregiver burden, psychological distress, frailty and functional dependency of a relative with advanced dementia. Persons with dementia and their caregivers (102 dyads) participated in this Portuguese community based cross-sectional study. Data were collected using the Clinical Dementia Rating Scale, a sociodemographic questionnaire, the Zarit Burden Interview, the Brief Symptoms Inventory and the Edmonton Frail Scale. Alzheimer's disease was the most common type of dementia among the recipients of care, who showed moderate (42.2%) to severe (52.9%) dementia. Among them 35.3% exhibited moderate and 45.1% severe frailty. Family caregivers reported moderate (76.5%) to severe burden (18.6%). Psychological distress was very high among family caregivers. Results show that people with dementia exhibited moderate (35.3%) or severe frailty (45.1%) and that a severe frailty was found in people with moderate dementia. A one-way ANOVA was conducted between the Global Severity Index and some sociodemographic variables. ANOVA reached p < .01 for employment status of the caregiver, assistance and professional support, and psychiatric history; and p = 0.01 for caregiver age and years of caregiving. Although caregivers reported benefit from the supportive approach offered by the multidisciplinary home care team, high levels of distress and associated burden were found, which might decrease their capacity to care for the person with dementia and their own health and well-being.

Neurocognitive Impairment: Addressing Couple and Family Challenges

Conditions involving neurocognitive impairment pose enormous challenges to couples and families. However, research and practice tend to focus narrowly on immediate issues for individual caregivers and their dyadic relationship with the affected member. A broad family systems approach with attention to family processes over time is needed in training, practice, and research. In this paper, Rolland's Family Systems Illness model provides a guiding framework to consider the interaction of different psychosocial types of neurocognitive conditions and their evolution over time with individual, couple, and family life-course development. Discussion addresses key family and couple issues with mild-to-severe cognitive impairment and progressive dementias, including: communication, multigenerational legacies, threatened future neurocognitive disability, ambiguous loss, decisional capacity, reaching limits, placement decisions, issues for adult children and spousal caregivers, and the transformation of intimate bonds. Principles and guidelines are offered to help couples and families master complex challenges, deepen bonds, and forge positive pathways ahead.

The Impact of Dementia on Family Caregivers: What Is Research Teaching Us?

Dementia family caregiving has been the focus of research for decades. Much has been learned about the negative impact of caregiving as well as characteristics that may be protective. This paper explores themes in caregiving pertinent to clinicians and researchers working with dementia family caregivers: the psychological, subjective, and physical outcomes of caregiving, ways in which dementia alters relationships between the patient and caregiver, and strategies for improving outcomes for caregivers. Suggestions for next steps in research and clinical care are made.

Impact of the REACH II and REACH VA Dementia Caregiver Interventions on Healthcare Costs

OBJECTIVE

Examine caregiver and care recipient healthcare costs associated with caregivers' participation in Resources for Enhancing Alzheimer's Caregivers Health (REACH II or REACH VA) behavioral interventions to improve coping skills and care recipient management.

DESIGN

RCT (REACH II); propensity-score matched, retrospective cohort study (REACH VA).

SETTING

Five community sites (REACH II); 24 VA facilities (REACH VA).

PARTICIPANTS

Care recipients with Alzheimer's disease and related dementias (ADRD) and their caregivers who participated in REACH II study (analysis sample of 110 caregivers and 197 care recipients); care recipients whose caregivers participated in REACH VA and a propensity matched control group (analysis sample of 491).

MEASUREMENTS

Previously collected data plus Medicare expenditures (REACH II) and VA costs plus Medicare expenditures (REACH VA).

RESULTS

There was no increase in VA or Medicare expenditures for care recipients or their caregivers who participated in either REACH intervention. For VA care recipients, REACH was associated with significantly lower total VA costs of care (33.6%). VA caregiver cost data was not available.

CONCLUSION

In previous research, both REACH II and REACH VA have been shown to provide benefit for dementia caregivers at a cost of less than $5/day; however, concerns about additional healthcare costs may have hindered REACH's widespread adoption. Neither REACH intervention was associated with additional healthcare costs for caregivers or patients; in fact, for VA patients, there were significantly lower healthcare costs. The VA costs savings may be related to the addition of a structured format for addressing the caregiver's role in managing complex ADRD care to an existing, integrated care system. These findings suggest that behavioral interventions are a viable mechanism to support burdened dementia caregivers without additional healthcare costs.
