Stress in the caregivers of Alzheimer's patients: an experimental investigation in Italy

HIGEA: An Intelligent Conversational Agent to Detect Caregiver Burden

Mental health disorders increasingly affect people worldwide. As a consequence, more families and relatives find themselves acting as caregivers. Most often, these are untrained people who experience loneliness, abandonment, and often develop signs of depression (i.e., caregiver burden syndrome). In this work, we present HIGEA, a digital system based on a conversational agent to help to detect caregiver burden. The conversational agent naturally embeds psychological test questions into informal conversations, which aim at increasing the adherence of use and avoiding user bias. A proof-of-concept is developed based on the popular Zarit Test, which is widely used to assess caregiver burden. Preliminary results show the system is useful and effective.

The Burden of Caring for Dependent Older People and the Resultant Risk of Depression in Family Primary Caregivers in Italy

Long-Term Care (LTC) for older people in need of care is a critical issue affecting the quality of life of family caregivers (as well as older people), encompassing both negative and positive caregiving experiences. Providing support to family caregivers is essential because they play a crucial role in sharing the societal burden of LTC for the growing frail older population. By presenting the results of a survey carried out in 2019–2020 in Central Italy, this study aims to describe the characteristics and estimate by a multivariate logistic model the correlates of depressive symptoms in 369 primary caregivers of dependent older people. Caregivers are mostly women who provide a high amount of care in terms of weekly hours as a result of insufficient assistance from public or private care services. More than half of the sample show depressive symptoms, indicating a fairly serious situation. Perceived burden is a strong predictor of depression. The findings offer suggestions and policy implications. The fragmentation of the care context should be addressed by allocating sufficient funding to expand the supply of public in-kind services and integrate cash-for-care schemes, thus alleviating the burden and mitigating the negative consequences of care on physical and mental health.

Pythagorean Self Awareness Intervention in Caregivers of Patients with Motor Disabilities

Caregiving for disabled people is a strenuous task often provided by family members, with adverse repercussions on the caregivers’ health. The aim of this study was to evaluate, for the first time, the effects of a novel cognitive-based stress management technique, the Pythagorean Self-Awareness Intervention (PSAI) on the stress levels and other cognitive and psychological characteristics of non-paid caregivers of patients with motor disability. In this quasi-experimental study, 59 caregivers of first-degree relatives with motor disabilities due to chronic neurological diseases, inpatients at a Rehabilitation Center, in Athens, Greece, were assigned to an intervention (PSAI, n=28) and a control group (received unstructured consultation, n=31). Psychological, cognitive, and sleep-related measurements (Zarit Burden Interview tool, Pittsburgh Sleep Quality Index, Self-Efficacy Scale, Depression, Anxiety and Stress Scale, Symbol Digit Modalities Test, California Verbal Learning Test-II, Brief Visuospatial Memory Test-Revised) were held at baseline and after 8 weeks (at completion of PSAI) in both groups. PSAI was found to decrease caregivers’ stress, depressive symptoms and anxiety and improve their sleep quality, visual memory, self-efficacy, and cognitive speed processing. Future randomized controlled studies are needed to investigate the effects of this novel intervention in larger samples of caregivers.

Health, social care and technological interventions to improve functional ability of older adults living at home: An evidence and gap map

Background

By 2030, the global population of people older than 60 years is expected to be higher than the number of children under 10 years, resulting in major health and social care system implications worldwide. Without a supportive environment, whether social or built, diminished functional ability may arise in older people. Functional ability comprises an individual's intrinsic capacity and people's interaction with their environment enabling them to be and do what they value.

Objectives

This evidence and gap map aims to identify primary studies and systematic reviews of health and social support services as well as assistive devices designed to support functional ability among older adults living at home or in other places of residence.

Search Methods

We systematically searched from inception to August 2018 in: MEDLINE, EMBASE, Cochrane Database of Systematic Reviews, CENTRAL, CINAHL, PsycINFO, AgeLine, Campbell Library, ASSIA, Social Science Citation Index and Social Policy & Practice. We conducted a focused search for grey literature and protocols of studies (e.g., ProQuest Theses and Dissertation Global, conference abstract databases, Help Age, PROSPERO, Cochrane and Campbell libraries and ClinicalTrials.gov).

Selection Criteria

Screening and data extraction were performed independently in duplicate according to our intervention and outcome framework. We included completed and on-going systematic reviews and randomized controlled trials of effectiveness on health and social support services provided at home, assistive products and technology for personal indoor and outdoor mobility and transportation as well as design, construction and building products and technology of buildings for private use such as wheelchairs, and ramps.

Data Collection and Analysis

We coded interventions and outcomes, and the number of studies that assessed health inequities across equity factors. We mapped outcomes based on the International Classification of Function, Disability and Health (ICF) adapted categories: intrinsic capacities (body function and structures) and functional abilities (activities). We assessed methodological quality of systematic reviews using the AMSTAR II checklist.

Main Results

After de-duplication, 10,783 records were screened. The map includes 548 studies (120 systematic reviews and 428 randomized controlled trials). Interventions and outcomes were classified using domains from the International Classification of Function, Disability and Health (ICF) framework. Most systematic reviews (n = 71, 59%) were rated low or critically low for methodological quality.The most common interventions were home-based rehabilitation for older adults (n = 276) and home-based health services for disease prevention (n = 233), mostly delivered by visiting healthcare professionals (n = 474). There was a relative paucity of studies on personal mobility, building adaptations, family support, personal support and befriending or friendly visits. The most measured intrinsic capacity domains were mental function (n = 269) and neuromusculoskeletal function (n = 164). The most measured outcomes for functional ability were basic needs (n = 277) and mobility (n = 160). There were few studies which evaluated outcome domains of social participation, financial security, ability to maintain relationships and communication.There was a lack of studies in low- and middle-income countries (LMICs) and a gap in the assessment of health equity issues.

Authors' Conclusions

There is substantial evidence for interventions to promote functional ability in older adults at home including mostly home-based rehabilitation for older adults and home-based health services for disease prevention. Remotely delivered home-based services are of greater importance to policy-makers and practitioners in the context of the COVID-19 pandemic. This map of studies published prior to the pandemic provides an initial resource to identify relevant home-based services which may be of interest for policy-makers and practitioners, such as home-based rehabilitation and social support, although these interventions would likely require further adaptation for online delivery during the COVID-19 pandemic. There is a need to strengthen assessment of social support and mobility interventions and outcomes related to making decisions, building relationships, financial security, and communication in future studies. More studies are needed to assess LMIC contexts and health equity issues.

A validation of the Croatian version of Zarit Burden Interview and clinical predictors of caregiver burden in informal caregivers of patients with dementia: a cross-sectional study

AIM

To validate the Croatian version of the Zarit Burden Interview (ZBI) and to investigate the predictors of perceived burden.

METHODS

This cross-sectional study involved 131 dyads of one informal caregiver family member and one patient with dementia visiting primary care practices (Health Care Center Zagreb-West; 10/2017-9/2018). Patient-related data were collected with the Mini-Mental-State-Examination, Barthel-index, and Neuropsychiatric-Inventory-Questionnaire (NPI-Q); caregiver-related data with the ZBI, and general information on caregivers and patients with a structured questionnaire. Principal-axis-factoring with varimax-rotation was used for factor analysis.

RESULTS

The caregivers' mean age was 62.1±13 years. They were mostly women (67.9%) and patients' children (51.1%). Four dimensions of ZBI corresponding to personal strain, frustration, embarrassment, and guilt were assessed and explained 56% variance of burden. Internal consistency of ZBI (α=0.87) and its dimensions (α1=0.88, α2=0.83, α3=0.72, α4=0.75) was good. Stronger cognitive and functional impairment of patients was associated only with personal strain, whereas more pronounced neuropsychiatric symptoms and the need for daily care were associated with more dimensions. Longer caregiver education suppressed embarrassment and promoted guilt. Guilt was higher in younger caregivers, caregivers of female patients, patients' children, and non-retired caregivers. In multivariate analysis significant predictors of higher overall burden were male sex of the patient, higher NPI-Q, the need for daily-care services, shorter duration of caregiving, non-spouse relationship, higher number of hours caring per-week, and anxious-depressive symptoms in a caregiver.

CONCLUSION

The Croatian version of ZBI is reliable and valid. Our data confirm that ZBI is a multidimensional construct. Caregivers may benefit from individually tailored interventions.

Optimism as a key to improving mental health in family caregivers of people living with Alzheimer's disease

Objective: The aim of the present work was to study the serial multiple mediating role of optimism, perceived social support and subjective burden in the relationship between objective burden and psychological distress in caregivers of people with Alzheimer´s Disease (AD).Method: One hundred and forty family caregivers of people living with AD were recruited from randomly selected Alzheimer Association Centres. They answered the General Health Questionnaire (GHQ), the Life Orientation Test-Revised (LOT-R), the Functional Social Support Questionnaire (DUKE.UNC), the Zarit Burden Interview (ZBI) and questions relating to gender, age and the amount of time spent on daily caregiving.Results: Results indicated that objective burden and subjective burden were both high in these caregivers. Optimism mediated on psychological distress through social support and through subjective burden with a full mediation role. When comparisons between indirect effects were performed, optimism was the mediator with the greatest effect between objective burden and psychological distress.Conclusion: This study highlights the indirect role of optimism and the advantages that interventions in optimism training in the early stages of the person with AD could produce. Thus, alleviating subjective burden and increasing perceived social support, which would lead to an improvement in the mental health of family caregivers of people with AD.

Informal carers' experience and outcomes of assistive technology use in dementia care in the community: a systematic review protocol

BACKGROUND

Dementia is one of the greatest health and care priorities globally. Caring for persons with dementia is a challenge and often leads to negative psychological, physiological and financial consequences for informal carers (family members or friends). Many informal carers experience moderate to severe levels of burden. Advances in technology have the potential to assist persons with dementia and their carers, through assistive technology (AT) devices such as electronic medication dispensers, robotic devices and motion detectors. However, little is known about informal carers' experience and the impact of these technologies on them. This review aims to investigate the outcomes and experience of carers of persons with dementia, who live at home and use AT.

METHOD

MEDLINE, Embase, CINAHL, AMED, ALOIS, PsycINFO, Trial registries and OpenGrey databases will be searched for studies of any design that have investigated carer experience and/or outcomes of AT use for persons with dementia living at home. Manual searches from reference lists of relevant papers will also be undertaken. Outcomes of interest are carers' self-reported outcomes (which include perceived burden, quality of life and wellbeing) and carer experiences (such as usefulness, benefits and disadvantages of AT and impact on caregiver/care receiver relationship). Two independent reviewers will screen identified papers with pre-defined eligibility criteria and extract data using a bespoke extraction form. Discrepancies will be resolved in discussion with a third reviewer. A synthesis of eligible studies and summary will be provided.

DISCUSSION

A systematic review of quantitative, qualitative and mixed methods evidence of informal carers' experience of AT use in dementia in the community will be carried out. It is anticipated that this will highlight (1) investigations on impact of AT use on carers, (2) outcome measures and experience questionnaires that have been used and (3) the types of studies carried out so far on this topic. The results from the review will be presented in a summary matrix of common types (e.g. mobile phones, alarms) and uses (e.g. communication, safety, personal care) of AT in dementia care and also identify AT that is not usually available through government or health system funding.

Utilization of Formal and Informal Care by Community-Living People with Dementia: A Comparative Study between Sweden and Italy

Background: Dementia is a public health priority with a dramatic social and economic impact on people with dementia (PwD), their caregivers and societies. The aim of this study was to contribute to the knowledge on how utilization of formal and informal care varies between Sweden and Italy. Methods: Data were retrieved from two trials: TECH@HOME (Sweden) and UP-TECH (Italy). The sample consisted of 89 Swedish and 317 Italian dyads (PwD and caregivers). Using bivariate analysis, we compared demographic characteristics and informal resource utilization. Multiple linear regression was performed to analyze factors associated with time spent on care by the informal caregivers. Results: Swedish participants utilized more frequently health care and social services. Informal caregivers in Italy spent more time in caregiving than the Swedish ones (6.3 and 3.7 h per day, respectively). Factors associated with an increased time were country of origin, PwD level of dependency, living situation, use of formal care services and occupation. Conclusions: Care and service utilization significantly varies between Sweden and Italy. The level of formal care support received by the caregivers has a significant impact on time spent on informal care. Knowledge on the factors triggering formal care resources utilization by PwD and their caregivers might further support care services planning and delivery across different countries.

Variance in caregiver burden predicted by patient behaviors versus neuropsychological profile

Informal caregivers provide the majority of care to persons with dementia; efforts to support caregivers' well-being are increasingly important in the context of limited formal healthcare supports. Informal caregiving is commonly associated with caregiver burden and burden may depend upon patient characteristics including neuropsychological profile, dementia severity, and dementia etiology. This study investigated predictors of caregiver burden in a sample of 213 Memory Clinic patients diagnosed with dementia and whose caregivers provided collateral information. Caregiver burden was similar irrespective of dementia etiology. Beyond the expected predictive value of dementia severity on caregiver burden, patient behavioral symptoms, functional dependence, and caregiver psychological distress were predictive of caregiver burden. In contrast, care-recipient neuropsychological performance did not predict burden. These findings suggest that beyond severity of dementia, specific behavioral disturbances predict caregiver burden which may have implications for programming and intervention aimed at supporting and sustaining caregivers in their role.

Understanding the educational and support needs of informal care-givers of people with dementia attending an outpatient geriatric assessment clinic

Informal (unpaid) care-givers of older people with dementia experience stress and isolation, causing physical and psychiatric morbidity. Comprehensive geriatric assessment clinics represent an important geriatrician-led model of dementia care. Our qualitative study examined the educational and support needs of care-givers of people diagnosed with dementia at a geriatric assessment clinic, resources used to address those needs and challenges experienced in doing so. We conducted structured thematic analysis of interviews with 18 informal care-givers. Participants’ narratives reflected four themes. First, care-givers sought information from varied sources, including the Alzheimer Society, the internet and clinic staff. Responsive behaviours, the expected progression of dementia and system navigation were topics of particular interest. Second, care-givers obtained assistance from public, for-profit and voluntary sources. Third, care-givers received little assistance. Two-thirds received fewer than four hours of help weekly from all sources combined, and none more than 15. Several received no assistance whatsoever. Publicly funded support workers’ tasks, and their timing, were often unhelpful. Finally, while numerous care-givers felt physical and emotional strain, and worried about how poor health impaired their care-giving, many hesitated to seek help. The needs of this unique population of informal care-givers can be met by improved home-care service flexibility, and access to trustworthy information about the expected progression of dementia and skills for managing behavioural and psychological symptoms.

The male familial caregiver experience of caring for persons with Alzheimer's disease from low socio-economic status: A South African perspective

The aim of this study was to explore the experiences of male familial caregivers of persons with Alzheimer’s disease from low socio-economic status using the ecological systems theory perspective. The data were obtained from 11 semi-structured interviews that were conducted with the familial caregivers of persons with Alzheimer’s disease. Data were analyzed using thematic analysis, where four main themes emerged, namely, relationship difficulties, understanding Alzheimer’s disease, support networks, and finding meaning and satisfaction in the caregiving role. Behavioral problems, erosion of the relationship with the significant other, familial conflict, experience of diagnosis, lack of information, lack of free time, and financial concerns were identified challenges facing caregivers. Provision of information, support groups, social support, community-based support, and finding meaning and satisfaction in the caregiving role were reported as resources that assist in caregiver coping. Men seem to be capable of providing effective care and are able to successfully manage in their caregiving role. Culture seems to play a significant role in help-seeking behavior and the approach to caregiving. The findings provide the basis for the specific needs of male caregivers that should be focused on in order to provide culturally appropriate services to enhance caregiver coping amongst male caregivers in similar settings.

Caregiver burden in Alzheimer's disease: Moderation effects of social support and mediation effects of positive aspects of caregiving

OBJECTIVES

Although there are many studies on the relationship between patient-related factors and negative caregiver outcomes, the specifics of this relationship are poorly understood. We aimed to examine whether caregiver social support moderated the relationship between patient factors and negative outcomes for caregivers of community-dwelling older adults with Alzheimer's disease (AD), and whether positive aspects of caregiving mediated this relationship.

METHODS

We conducted a cross-sectional study of patients diagnosed with AD from 2 hospitals and 3 communities in Taiyuan, China, and their caregivers. Latent moderated structural equations and the bias-corrected percentile bootstrap method were used to estimate the parameters of moderating and mediating effects, respectively.

RESULTS

Social support significantly moderated the effects of AD patient cognitive function (P < 0.001) and depression (P = 0.001) on caregiver burden. Positive aspects of caregiving completely mediated the association between patient depression and caregiver burden (P = 0.006), caregiver anxiety (P = 0.007), and caregiver depression (P = 0.034).

CONCLUSIONS

The findings identify social support as a moderator and positive aspects of caregiving as a mediator of the relationship between patient-related factors and negative caregiver outcomes. The results suggest that health care providers must offer more effective social support for caregivers. In addition, prompt identification of patient and caregiver emotional states could help to improve quality of life.

The Effects of the Perception of Being Recognized by Patients With Alzheimer Disease on a Caregiver's Burden and Psychophysical Health

Caring for a patient with Alzheimer disease (AD) represents a real challenge that can have considerable long-term psychological and physical consequences. The aim of this study was to evaluate the impact of the perception of being recognized on both the psychophysical health and the level of burden reported in caregivers of patients with AD. The secondary aim was to evaluate the association between the use of a home care assistance service and the burden and psychophysical health in caregivers. The Caregiver Burden Inventory (CBI), the 36-item Short-Form Health Survey (SF-36), and a visual analog scale (VAS) to evaluate the level of perception of being recognized were administered to 31 caregivers of patients with AD. Data were also collected from patients with AD using the Mini-Mental State Examination (MMSE). The level of perception of being recognized was significantly and negatively correlated with total burden ( r = -0.36; P = .045) and objective burden ( r = -0.53; P = .002). It was also significantly and positively correlated with the MMSE score ( r = 41; P = .02). Regression models showed that only the perception of being recognized, and not MMSE, significantly predicted lower caregiver objective burden scores. Furthermore, the use of a home care assistance service significantly predicted higher caregiver physical functioning. The perception of being recognized by an AD relative significantly predicted the caregiver's objective burden associated with a shortage of time. The use of a home care assistance service also resulted in a promotion in the caregiver's social functioning. Further studies are needed to confirm these results.

Caregiver burden in Alzheimer-type dementia and psychosis: A comparative study from India

BACKGROUND

Caregiver burden in dementia is an important area of research. Providing care for a relative can be a potent source of chronic stress and can have deleterious consequences for both the physical and emotional health of caregivers. This study aims to evaluate the burden of care in caregivers of patients with Alzheimer-type dementia and compare it with elderly psychosis; and to also study the factors that influence burden of care in Alzheimer's dementia.

METHODS

Thirty-two caregiver-patient dyads of Alzheimer-type dementia were compared with thirty-two caregiver-patient dyads of psychosis. Cognitive assessment, abilities to perform activities of daily living and severity of dementia was assessed in the patients. Zarit Burden Interview was used to study the caregiver burden in both groups.

RESULTS

The mean burden score in dementia caregivers was high at 47.7, whereas the mean burden score for elderly psychosis caregivers was lesser at 33.6, and this difference in mean burden scores was found to be statistically significant. Spouses had the highest mean burden scores of 53.48. Caregiver burden in dementia was positively correlated with cognitive impairment and inability to carry out ADLs. Presence of psychological distress in caregivers was also an indicator for greater caregiver burden in dementia.

CONCLUSION

The study revealed that dementia carries a greater caregiver burden when compared with elderly patients with psychosis. Innovative interventions are needed to remove burden from caregiving, making it a meaningful practice integral to the Indian society.

Caregiver Burden in Different Stages of Alzheimer's Disease

With an increasing number of patients being diagnosed with Alzheimer's disease (AD) daily, it has become one of the major problems in public health. The increase in the number of dementia patients in low- and middle-income countries is expected to be much more than that in developed countries. As a result, the economic burden of dementia, both worldwide and in Turkey, is growing. Moreover, AD leads to emotional burdens and psychological distress in family member(s) and caregiver(s) alongside the patient. Each stage of AD imposes different responsibilities on caregivers, increasing their burden. The suffering and emotional burdens of caregivers from these responsibilities lead to a decreased quality of life and disturbed body physiology. Incapacity, despair, weariness, and loneliness are the hidden emotions of this iceberg. This review aims to gather the results of studies on caregiver burden in different stages of AD, attract attention to those results that may have been ignored in Turkey, and shed light on the solutions required to overcome the problems in caregiving of AD patients.

Living with mild to moderate Alzheimer patients increases the caregiver's burden at 6 months

The objective of our study was to demonstrate that living with a person affected by mild to moderate Alzheimer's disease can lead to an increased perception of the caregiver's burden using the Caregiver Burden Inventory (CBI). The sample consisted of 153 dyads, caregiver-patient. At baseline, a greater perception of the caregiver's burden was observed in the live-in caregivers. A further increase in the total burden of the live-in caregivers was noticed at the 6-month follow-up. More specifically, with the inclusion of correction factors such as the caregiver's age and the CBI subscales at baseline, the social and emotional burden becomes statistically significant (P < .001). The present paper confirms our hypothesis that live-in caregivers perceive a greater burden than nonlive-in, and this difference increases further after 6 months. The difference in involvement between live-in and nonlive-in caregivers could be the foundation to tailor more specific interventions.

Measuring the Caregiver Burden of Caring for Community-Residing People with Alzheimer's Disease

Objectives

To assess the direct and indirect effects of patient or caregiver factors on caregiver burden of caring for community-residing people with mild Alzheimer’s disease (AD).

Methods

We conducted a cross-sectional study of patients diagnosed with AD from two hospitals and three communities in Taiyuan, China and their caregivers. For this survey, 200 patients with mild AD and their caregivers were selected. Caregivers were asked to provide sociodemographic information including age, gender, relationship with the patient, level of education, and number of contact hours per week with the patient. Caregiver burden was assessed using the Caregivers Burden Inventory. The caregivers also completed other measures including the Positive Aspects of Caregiving, the Family Adaptation, Partnership, Growth, Affection, and Resolve, and the Social Support Rating Scale. The patients with AD completed the Montreal Cognitive Assessment; their caregivers completed the Activities of Daily Living Scale and a questionnaire about the patients’ Behavioral and Psychological symptoms of Dementia. The main outcome in this study was caregiver burden. The care receivers’ level of cognitive function, physical function, and behavioral problems were treated as original stress; the primary appraisal variable was measured as the number of hours of caregiving in the previous week reported by the caregiver. Mediator variables included perceived social support, family function, and caregiving experience. Path analysis was used to build the interrelationship among caregiver burden and patient or caregiver factors.

Results

A lower level of cognitive function in patients (r = −0.28, p<0.001) and longer hours of caregiving (r = 0.17, p = 0.019) were related to increased caregiver burden. Greater social support (r = −0.23, p<0.001), family function (r = −0.17, p = 0.015) and caregiving experience (r = −0.16, p = 0.012) were related to decreased caregiver burden. Social support (r = 0.16, p = 0.040) and family function (r = 0.25, p = 0.002) were directly related to patients’ level of cognitive functioning, but were mediator factors between level of cognitive function in patients and caregiver burden. Similarly, social support was a mediator factor between patients' daily function (r = −0.23, p = 0.004) and caregiver burden; while caregiving experience mediated the link between behavioral and psychological symptoms in patients (r = 0.36, p<0.001) and caregiver burden.

Conclusion

Level of cognitive function and hours of caregiving were directly related to caregiver's burden. Social support, family function and caregiving experience could mediate the relationship between patient factors and caregiver burden. Focusing on patient factors and promoting caregiver care will be helpful in lowering the perceived burden of caregiving.

Depressive symptoms in caregivers of patients with dementia: demographic variables and burden

OBJECTIVE

Individuals suffering from dementia are affected by a progressive and significant global deterioration and, consequently, might require longer assistance in the advanced stage of the illness. The illness is a great burden on the person who takes care of a patient, namely, the caregiver. This study aims to analyze the presence and relationship of specific sociodemographic variables, subjective burden, and depressive symptoms among caregivers of patients with dementia.

METHODS

The participants of this study were caregivers at a health care unit for the elderly in southern Italy. An evaluation of the burden of patients with dementia on caregivers was carried out using the Caregiver Burden Inventory (CBI) and depressive symptoms using the Self-Rating Depression Scale (SDS).

RESULTS

A total of 150 caregivers completed the study. In all, 83 (55%) caregivers showed a total CBI score ≥36, of whom 70% showed pathological depression scores in SDS. According to SDS, 28 (19%) caregivers showed a total CBI score from 24 to 36, of whom 32% were depressed. Depression was present in 5% of the caregivers whose CBI score was <24. Hence, an association between burden and depression was evident (χ(2)=47.446, P<0.001). A multiple linear regression analysis showed that depression (adjusted R(2)=0.622, F=50.123, P<0.001) was associated with higher physical (β=0.666, P=0.001) and developmental (β=0.712, P<0.001) burdens, lower socioeconomic status (β=-4.282; P=0.002), higher level of urbanicity (β=3.070; P=0.012), and advanced age (β=2.132; P=0.08).

CONCLUSION

Our study confirms the presence of depressive symptoms in a large number of caregivers with high burden. Nevertheless, this study demonstrates that depressive symptoms are mainly associated with sociodemographic variables and, to a lesser degree, physical and developmental burdens.

Which variable is the strongest adjusted predictor of quality of life in caregivers of patients with dementia?

BACKGROUND

The central role of family in caregiving for patients with dementia is now widely acknowledged. However, in playing this role, caregivers may neglect their health and quality of life (QOL). The purposes of present study were to measure caregivers' QOL and to determine its adjusted predictors via multiple regression models.

METHODS

We used sequential sampling to recruit 153 patients and their caregivers from the Iran Alzheimer Association in our cross-sectional study. A single-item question with a Likert scale was applied to measure QOL. A multiple linear regression model was used to determine the adjusted predictors of QOL.

RESULTS

Of the responding caregivers, 22.8% reported their QOL as poor or very poor. Caregiver burden, the main caregiver's age, the Global Deterioration Scale, and the number of caregivers were introduced as adjusted predictors of QOL.

CONCLUSIONS

Caregiver burden was proposed as the strongest adjusted predictor for caregivers' poor QOL. Therefore, it seems that interventions to reduce caregiver burden can be effective in enhancing caregivers' QOL.

Sources of parental burden in a UK sample of first-generation North Indian Punjabi Sikhs and their white British counterparts

OBJECTIVE

The correlates of parental burden in schizophrenia may differ between ethnic groups, but few studies have examined this in a UK setting. Our aim was to identify the correlates of burden in a UK sample of first-generation North Indian Punjabi Sikh parents and their white British counterparts.

METHOD

Test the association of burden with a series of clinical, social and service use variables and control for potential confounding factors in a model predicting drivers of burden in a combined sample of the above.

RESULTS

The strongest correlates of burden were patient symptoms and parental distress. Differences in correlates of burden between the groups emerged when individual components of service use and parental social network were tested. The group comparisons also revealed differences in expressed emotion (EE) and social networks.

CONCLUSION

The similarities in sources of burden between the groups could be explained by a commonality of sociocultural and economic experience, resulting from the successful acculturation and affluence of this British Sikh group. The differences between the groups may be related to enduring cultural factors such as kin support, since larger family groups were associated with low burden in the British Sikh group. The nature of EE in this British Sikh group may explain why it was not associated with burden in this sample.

Predictors of comprehensive stimulation program efficacy in patients with cognitive impairment. Clinical practice recommendations

BACKGROUND

The aim of the present study was to identify which factors may predict the best response to a comprehensive stimulation program in patients with dementia and mild cognitive impairment (MCI) as well as in their caregivers.

METHODS

A six-month longitudinal study has been performed on 145 patients (55 with MCI and 90 with dementia), participating to a cognitive motor rehabilitation program, and their 131 caregivers, attending informational/psychoeducational interventions. Mini mental state examination, Alzheimer's Disease Assessment Scale-Cognition, and Clinician's Interview-Based Impression of Change-plus were used as primary outcome measures.

RESULTS

Sixty-eight (46.9%) of the 145 subjects were classified as clinical responders. At baseline, responders had a significant less insight impairment, larger functional ability as well as less delusions, euphoria, and aberrant motor behaviors than the non-responder. After 6 months along with an improvement in cognition, responders showed decrease in behavioral disturbances and severity of the disturbances. During the 6 months of analysis, stability has been observed in caregiver's burden distress. After 6 months, the caregivers of MCI responders have their burden reduced.

CONCLUSIONS

The high level of insight, the preserved functional abilities as well as the lack of severe delusions, euphoria, and aberrant motor behaviors are significant predictors of responsiveness to stimulation program.

The use of formal and informal care in early onset dementia: results from the NeedYD study

OBJECTIVE

Early onset dementia (EOD) poses specific challenges and issues for both the patient and (in)formal care. This study explores the use of (in)formal care prior to institutionalization, and its association with patient and caregiver characteristics.

DESIGN/SETTING

Participants were part of a community-based prospective longitudinal study of 215 patients and their informal caregivers.

PARTICIPANTS

Baseline data of a subsample of 215 patient-caregiver dyads were analyzed.

MEASUREMENTS

Analyses of covariance were performed to determine correlates of (in)formal care use assessed with the Resource Utilization in Dementia (RUD)-Lite questionnaire.

RESULTS

Informal care had a 3:1 ratio with formal care. Supervision/surveillance constituted the largest part of informal care. In more than half of cases, patients had only one informal caregiver. The amount of informal care was associated with disease severity, showing more informal care hours in advanced disease stages. Fewer informal care hours were related to more caregiver working hours, especially in younger patients. The amount of formal care was related to disease severity, behavioral problems, and initiative for activities of daily living.

CONCLUSION

In EOD, it appears that family members provide most of the care. However, other social roles still have to be fulfilled. Especially in spousal caregivers of younger patients in advanced disease stages, there is a double burden of work and care responsibilities. This finding also indicates that even within the EOD group there might be important age-related differences. The relatively higher amount of formal care use during advanced disease stages suggests a postponement in the use of formal care.

Frequência e repercussão da sobrecarga de cuidadoras familiares de idosos com demência

OBJETIVOS: Investigar a prevalência e os fatores associados a sobrecarga, transtornos mentais comuns e autopercepção da memória das cuidadoras familiares de idosos com demência. MÉTODOS: Estudo transversal e analítico, com amostra de conveniência de 58 cuidadoras familiares que participaram dos grupos de apoio à família da pessoa com demência. Instrumentos utilizados: questionário sociodemográfico, de hábitos de vida, morbidade referida, uso de medicamentos e de serviços de saúde, Escala Zarit Burden Interview, Self Report Questionnaire 20 (SRQ -20), Prospective and Retrospective Memory Questionnaire (PRMQ-10) e Escala Funcional de Pfeffer. RESULTADOS: Predominaram as seguintes características: 42 eram filhas (72,4%), adultas (63,8%), com idade inferior a 60 anos (63,8%) e grau de instrução superior completo (46,6%). Dentre os problemas de saúde autorreferidos, os mais prevalentes foram dores nas costas (63,8%), problemas articulares (60,3%), colesterol alto (51,7%) e hipertensão arterial (44,8%). Os medicamentos mais utilizados foram os anti-hipertensivos (38,9%) e antidepressivos (31,5%). Os dados evidenciaram que o grau de sobrecarga foi de leve a moderado (51,7%). No modelo final, observou-se associação da sobrecarga com ocupação (p=0,014), prática de esporte (p=0,010), ter religião (p=0,032) e tempo na função de cuidadora (p=0,046). Com relação aos transtornos mentais menores, as associações relevantes foram prática de esporte (p=0,028), dores nas costas (p=0,026) e tempo de cuidado diário (p=0,037). As queixas de memória foram associadas estatisticamente ao uso de antidepressivo (p=0,034). CONCLUSÕES: Apesar das informações e orientações sobre a atividade de cuidar nos grupos de apoio, as cuidadoras ainda apresentaram sobrecarga, reforçando a necessidade de um trabalho preventivo, de orientação e tratamento.

Prevalence and comorbidity of prolonged grief disorder in a sample of caregivers of patients in a vegetative state

Previous studies have shown that Prolonged Grief Disorder (PGD), Post-traumatic Stress Disorder (PTSD) and major depression are autonomous nosological entities. The present study aims at further analyzing the relationship among them in a sample of caregivers of patients in Vegetative State (VS) or Minimally Conscious State (MCS). We also investigated factors predicting the development of PGD. We sampled 40 Caregivers of patients in VS or MCS consecutively admitted to long-term care units. Caregivers were administered the PG-12, the Depression Questionnaire, the SCID I and the Davidson Trauma Scale. Six participants (15%) fulfilled the criteria for PGD, 25% (N = 10) for depression and 25% (N = 10) for PTSD. Although significant correlations emerged among symptom domains of the three disorders, no relevant association was found between a diagnosis of PGD, depression and PTSD. The severity of PTSD symptoms was found to be predictive of PGD. Clinical implications are discussed.

Effect of second-generation antipsychotics on caregiver burden in Alzheimer's disease

BACKGROUND

Alzheimer's disease (AD) imposes a severe burden upon patients and their caregivers. Severity of psychiatric symptoms and behavioral disturbances is an important determinant of caregivers' experience of burden. These symptoms may be improved with atypical antipsychotic treatment.

OBJECTIVE

Data from the Clinical Antipsychotic Trials of Intervention Effectiveness-Alzheimer's Disease (CATIE-AD) trial were used to evaluate the effect of atypical antipsychotics versus placebo on the experiences of caregivers of outpatients with AD.

METHOD

We compared the effect of atypical antipsychotic drugs (olanzapine, risperidone, or quetiapine-considered together as a group) versus placebo on the experiences of caregivers of AD outpatients (diagnosed according to DSM-IV-TR). We also evaluated whether improvement in patients' psychiatric and behavioral symptoms mediated the relationship between drug treatment and caregiver burden. The CATIE-AD trial, conducted from April 2001 through November 2004, included outpatients (mean age = 77.9 years [SD = 7.5 years]) in usual care settings and assessed treatment effectiveness over a 9-month period at 42 US sites. In a set of secondary analyses, data from CATIE-AD participants who had at least 1 postbaseline outcome assessment and data from their caregivers were examined in an intention-to-treat (ITT) analysis (N = 361). A phase 1-only analysis was conducted including only observations while patients were receiving the initially randomized drug (N = 153). The Burden Interview, the Beck Depression Inventory, and the Neuropsychiatric Inventory (NPI) Caregiver Distress Scale were used to evaluate caregiver burden.

RESULTS

In both ITT and phase 1-only analyses, caregivers of patients treated with second-generation antipsychotics scored significantly lower than caregivers of patients receiving placebo on both the Burden Interview (P = .0090) and the NPI Caregiver Distress Scale (P = .0209). These differences appeared to have been mediated by lower levels of agitation, hostility, and psychotic distortions.

CONCLUSION

In AD patients with symptoms of psychosis, agitation, or aggressive behavior, medications can have a small but significant impact on caregiver burden.

Compassion fatigue: an application of the concept to informal caregivers of family members with dementia

Introduction. Compassion fatigue is a concept used with increasing frequency in the nursing literature. The objective of this paper is to identify common themes across the literature and to apply these themes, and an existing model of compassion fatigue, to informal caregivers for family members with dementia. Findings. Caregivers for family members with dementia may be at risk for developing compassion fatigue. The model of compassion fatigue provides an informative framework for understanding compassion fatigue in the informal caregiver population. Limitations of the model when applied to this population were identified as traumatic memories and the emotional relationship between parent and child, suggesting areas for future research. Conclusions. Research is needed to better understand the impact of compassion fatigue on informal caregivers through qualitative interviews, to identify informal caregivers at risk for compassion fatigue, and to provide an empirical basis for developing nursing interventions for caregivers experiencing compassion fatigue.

Six-month walking program changes cognitive and ADL performance in patients with Alzheimer

Motor inactivity is typical in the later stages of Alzheimer's disease although there is evidence that physical exercise can reduce depression and enhance performance of daily activities. The aim of this study was to determine whether a walking program could reduce the functional and cognitive decline of elderly nursing home residents in the later stages of Alzheimer's disease. A total of 21 patients (84 ± 5 years) were randomly assigned to a walking program (WG) or to a control group (CG). A 6-minute walking test (6WT), the Barthel index of activities of daily living (ADLs), and Mini-Mental State Examination (MMSE) tests were performed before and after 24 weeks of the program. The WG showed significant improvement in the 6WT (20%) and ADLs (23%), while the CG decreased in MMSE (-47%), the WG had a slower decline (-13%). This study indicates that it is possible to stabilize the progressive cognitive dysfunctions in nursing home residents with Alzheimer's disease through a specific walking program.

Dementia in the family: Two Norwegian case studies

With increasing longevity the numbers of people suffering from dementia are rising. This development creates problems and dilemmas for public health care agencies as well as close relatives who are expected to provide care. This article is based on two Norwegian case studies of spouses and adult children who give care to elderly people – both males and females – with dementia. Nine families were included in these studies, and a total of 27 persons were interviewed (husbands, wives, sons and daughters). Central topics discussed in this article are the initial phases of the illness, the heavy demands of home care, and dilemmas associated with multiple caregiving roles. The analyses demonstrate the many challenges encountered by people with family members who suffer from dementia.

Experiences and perceptions of culturally and linguistically diverse family carers of people with dementia

Dementia incidence rates are rapidly increasing among culturally and linguistically diverse (CALD) Australians, and there is very little local research to inform practice. In response, a qualitative study employing focus group methods was undertaken with carers from 4 CALD communities-Arabic-speaking, Chinese-speaking, Italian-speaking and, Spanish-speaking. The study examined the experiences and perceptions of these family carers with regard to their caregiving for a person living with dementia (PLWD). Analysis revealed that while considerable similarities exist across the experiences and perceptions of carers from all 4 CALD communities, there were nevertheless some important distinctions across the different groups. These study findings have significant implications for those working with CALD communities.

Recruiting and retaining family caregivers to a randomized controlled trial on mindfulness-based stress reduction

Caregivers for a family member with dementia experience chronic long-term stress that may benefit from new complementary therapies such as mindfulness-based stress reduction. Little is known however, about the challenges of recruiting and retaining family caregivers to research on mind-body based complementary therapies. Our pilot study is the first of its kind to successfully recruit caregivers for a family member with dementia to a randomized controlled pilot study of mindfulness-based stress reduction. The study used an array of recruitment strategies and techniques that were tailored to fit the unique features of our recruitment sources and employed retention strategies that placed high value on establishing early and ongoing communication with potential participants. Innovative recruitment methods including conducting outreach to health plan members and generating press coverage were combined with standard methods of community outreach and paid advertising. We were successful in exceeding our recruitment goal and retained 92% of the study participants at post-intervention (2 months) and 90% at 6 months. Recruitment and retention for family caregiver interventions employing mind-body based complementary therapies can be successful despite many challenges. Barriers include cultural perceptions about the use and benefit of complementary therapies, cultural differences with how the role of family caregiver is perceived, the use of group-based designs requiring significant time commitment by participants, and travel and respite care needs for busy family caregivers.

Quality of life and depression in carers of patients with early onset dementia

OBJECTIVE

To investigate the quality of life (QoL) and depression and its correlates in carers living with early onset dementia (EOD) patients.

METHOD

The subjects were 49 carers, either married to or cohabiting with EOD patients, 38 with Alzheimer's disease and 11 with other types of dementia. The Quality of Life - Alzheimer Disease scale (QoL-AD) and Geriatric Depression Scale-15 items (GDS-15) were used.

RESULTS

The mean QoL score for the carers was 37.9 (SD 5.5) and the mean GDS-15 score 5.1 (SD 2.9). Linear regression analyses with QoL and GDS-15 score as dependent variables were performed. Increased age of the carer (B = 0.32) and greater insight of the patients (B = -0.186) were significantly associated with a better QoL for the carer. Being married (B = 2.10), having children together with the patient (B = 1.61) and being the carer of a patient with cardiovascular disease (B = 2.28) were associated significantly with a higher GDS-15 score, whereas being the carer of a patient who received domiciliary nursing care (B = -2.29) was significantly associated with a lower GDS-15 score.

CONCLUSION

The QoL for carers of EOD patients corresponds positively with the increased age of carers and with patients' insight into their condition. Increased depressive symptomatology in carers was associated with being married, having offspring and caring for a patient with dementia and a co-morbid cardiovascular disease. A reduction in depression was seen in carers when the patients received domiciliary nursing care.

Strategies for the relief of burden in advanced dementia care-giving

AIM

This paper is a report of a study conducted to uncover the strategies that women caregivers of relatives with advanced dementia use to rest from care-giving.

BACKGROUND

Respite consists of activities and situations that briefly take caregivers away from their care-giving responsibilities. Qualitative studies are focusing on respite as an outcome and are deepening our knowledge about the experience of caregivers' rest. The strategies that caregivers use to relieve the burden, however, are not fully known.

METHOD

A qualitative approach was used influenced by the work of Charmaz's constructivist grounded theory. Twenty-three female primary caregivers of relatives with advanced dementia participated in semi-structured interviews between November 2006 and March 2009 in Spain. Data collection was guided by the emergent analysis and ceased when no more relevant variations in the categories were found.

FINDINGS

Taking leave from the life of care-giving is the general strategy that caregivers use to rest from their caregivers selves. The key issue is to be able to connect with a different world from that of care-giving. Three strategies that participants use to leave the life of care-giving follow: (1) Connecting with one's own life, (2) building moments of life in common with the sick relative and (3) keeping in touch with care-giving.

CONCLUSION

To have respite from care-giving implies distancing oneself from the care-giving identity and reveals the caregiver's need for alternative selves to have true breaks from caring. Nurses are in a unique situation to foster respite as an inner experience.

Assessing sleep architecture in dementia caregivers at home using an ambulatory polysomnographic system

Findings from previous research assessing sleep quality in caregivers are inconsistent due to differences in sleep assessment methods. This study evaluated sleep in dementia caregivers using a comprehensive sleep assessment utilizing an ambulatory polysomnography (PSG) device. A total of 20 caregivers and 20 noncaregivers rated their perceived sleep quality, stress, and depressive symptoms; provided samples of cortisol and inflammatory biomarkers; and completed an objective sleep assessment using a portable PSG device. Caregivers reported greater perceived stress than noncaregivers. Next, the groups had different sleep architecture: caregivers spent less proportion of their sleep in restorative sleep stages compared to noncaregivers. Further, levels of C-reactive protein and awakening salivary cortisol were greater in caregivers than in noncaregivers, and these measures were related to sleep quality. Our findings indicate that sleep disruption is a significant concomitant of caregiving and may affect caregiver's health. Sleep quality of caregivers might be a useful target for a clinical intervention.

Integration of the pleasant events and activity restriction models: development and validation of a "PEAR" model of negative outcomes in Alzheimer's caregivers

This study examined an activity restriction/pleasurable activities mismatch model for psychosocial and health-related outcomes. A total of 108 spousal caregivers of patients with Alzheimer's Disease (AD) were assessed for their experience of social and recreational activities over the past month as well as their perception of how restricted they were for engaging in social and recreational activities. Participants were divided into three groups based on their reported activities and activity restriction: HPLR=High Pleasant Events+Low Activity Restriction (i.e., reference group; N=28); HPHR/LPLR=Either High Pleasant Events+High Activity Restriction or Low Pleasant Events+Low Activity Restriction (N=43); LPHR=Low Pleasant Events+High Activity Restriction (N=37). We hypothesized that participants reporting low pleasant events combined with high activity restriction (LPHR) would demonstrate greater disturbance relative to other two groups in multiple outcome domains, including: (a) greater mood disturbance, (b) greater use of negative coping factors, (c) reduced use of positive coping strategies, (d) reduced report of psychological resource factors (e.g., personal mastery, self-efficacy), and (e) increased report of subjective health difficulties (e.g., sleep disturbance). Results generally supported our hypotheses, suggesting that assessment of both constructs is important for best predicting quality of well-being in AD caregivers, and potentially for establishing maximal effect in behavior therapy for caregivers.

Caregiver distress associated with behavioral and psychological symptoms in mild Alzheimer's disease

The aim of this study was to analyze the relationship between Caregiver Distress and Behavioral and Psychological Symptoms in Dementias (BPSD) in mild Alzheimer’s disease.

Balneotherapy, prevention of cognitive decline and care the Alzheimer patient and his family: outcome of a multidisciplinary workgroup

According to the latest forecasts of the INSEE - Institut National de la Statistique et des Etudes Economiques (National Statistics and Economic Studies Institute), ageing of the French population will increase between 2005 and 2050: whereas 20.8% of the population living in continental France reached the age of 60 years or more in 2005, this proportion would be of 30.6% in 2035 and 31.9% in 2050. In 2050, 22.3 million persons will have reached the age of 60 years or more compared to 12.6 million in 2005, increasing by 80% in a 45-year period. In line with the actual age pyramid, ageing is unavoidable, as those who will reach 60 years of age in 2050 are already born (in 1989 or before). This expansion will be most important between 2006 and 2035, when the numerous "baby-boom" generations born between 1946 and 1975, will reach these ages. In future years, lifespan improvement will only emphasize this increase. Even if life expectancy stabilizes at the 2005 level, the number of seniors reaching 60 years or more would still increase to 50% between 2005 and 2050. This issue is identical in all countries of the European Union. Ageing is a major risk factor for dementia that will considerably worsen in the next years, if no curative therapies are found. Today, 25 million persons in the world suffer from Alzheimer's disease (AD). In France, it is estimated that 860,000 persons are affected and that 225,000 news cases are annually diagnosed. After 75 years of age, more than 20% of women and 13% of men are concerned. Forecasts for the coming years are frightening. Considering ageing of the population, the number of Alzheimer's disease cases should raise to 1.3 million in 2020 (20 patients for 1000 inhabitants) ant 2.1 million in 2040 (30 patients for 1000 inhabitants).

The caregiver's burden of Alzheimer patients: differences between live-in and non-live-in

The objective of our study was to describe the burden of a sample of 208 live-in/non-live-in caregivers of patients with Alzheimer's disease (AD). We analyzed the statistical correlation between Caregiver Burden Inventory (CBI) and the live-in/non-live-in caregiver status, and between the ''objective burden,'' the cognitive deterioration, functional ability, and psychic and behavioral disorders. Using analysis of variance (ANOVA), the live-in groups of caregivers were compared to each subscale and to the total CBI. Living with a patient causes a bigger burden associated to the ''developmental and physical burden,'' which is affected more by the functional impairment than by the cognitive-behavioral aspect. Understanding the aspects of this burden in the initial-intermediate phase of the disease and being able to monitor it over time could contribute to improving the interventions already in place, which affect burden, stress, and quality of life of caregivers and their sick family members.

Disclosure of the diagnosis of Alzheimer's disease: caregivers' opinions in a Brazilian sample

BACKGROUND

Disclosure of the diagnosis of Alzheimer's disease (AD) remains a contentious issue, and has been little studied in developing countries.

OBJECTIVE

To investigate the influence of socio-demographic factors and the experience of being a caregiver on opinion about disclosing AD diagnosis to the patient in a Brazilian sample.

METHOD

Caregivers of 50 AD patients together with 50 control participants that did not have the experience of being a caregiver of AD patient were interviewed using a structured questionnaire.

RESULTS

Most of the participants (73.0%) endorsed disclosure of the diagnosis, while caregivers were less prone to disclose (58.0%) than controls (88.0%; p=0.0007). Logistic regression confirmed that only the experience of being a caregiver was associated with a lesser tendency for disclosure endorsement.

CONCLUSION

The majority of participants was in favor of disclosing the diagnosis, but caregivers were less willing to disclose the diagnosis to the AD patient.

Diagnostic disclosure in Alzheimer's Disease: A review

Although growing, the literature on research into attitudes of general and specialized physicians towards disclosing the diagnosis of dementia and Alzheimer's disease (AD), or the current practice on AD disclosure, remains limited. Moreover, information is also scarce on what caregivers, or indeed patients themselves, wish to know with regard to their diagnosis. The goal of the present article was to present a review of the current available literature on the topic of truth telling in dementia, especially in AD. The studies discussed in this review were mainly conducted in Europe, particularly in the United Kingdom, as well as the United States. Disclosure of AD diagnosis is not a common practice among physicians. In the clinical context, the discussion on diagnosis disclosure can be valuable for improving the care of AD patients and their families.

The COACH prompting system to assist older adults with dementia through handwashing: an efficacy study

Background

Many older adults with dementia require constant assistance from a caregiver when completing activities of daily living (ADL). This study examines the efficacy of a computerized device intended to assist people with dementia through ADL, while reducing caregiver burden. The device, called COACH, uses artificial intelligence to autonomously guide an older adult with dementia through the ADL using audio and/or audio-video prompts.

Methods

Six older adults with moderate-to-severe dementia participated in this study. Handwashing was chosen as the target ADL. A single subject research design was used with two alternating baseline (COACH not used) and intervention (COACH used) phases. The data were analyzed to investigate the impact of COACH on the participants' independence and caregiver burden as well as COACH's overall performance for the activity of handwashing.

Results

Participants with moderate-level dementia were able to complete an average of 11% more handwashing steps independently and required 60% fewer interactions with a human caregiver when COACH was in use. Four of the participants achieved complete or very close to complete independence. Interestingly, participants' MMSE scores did not appear to robustly coincide with handwashing performance and/or responsiveness to COACH; other idiosyncrasies of each individual seem to play a stronger role. While the majority (78%) of COACH's actions were considered clinically correct, areas for improvement were identified.

Conclusion

The COACH system shows promise as a tool to help support older adults with moderate-levels of dementia and their caregivers. These findings reinforce the need for flexibility and dynamic personalization in devices designed to assist older adults with dementia. After addressing identified improvements, the authors plan to run clinical trials with a sample of community-dwelling older adults and caregivers.

An educational intervention to support caregivers of elders with dementia

The majority of home-dwelling elders with dementia are cared for by family members or friends. Interventions to support community-based caregivers are needed. A community-based seminar series was provided to 300 self-referred family caregivers with dementia. Participants were surveyed for caregiver burden and overload and perceived competence before and 6 months after the seminars. In all, 88 (29%) of participants completed a 6-month survey. Self-perceived caregiver competence improved (3.9 +/- 1.6 to 5.0 +/- 0.32, P < .006); a trend toward improvement in caregiver overload, and there was no change in caregiver burden. Caregivers with baseline parameters indicative of higher burden, overload, or lower competence showed improved scores at 6 months. The educational program was effective in improving competence and may have slowed the expected increase in burden associated with caring for those with a progressive dementia. Caregivers with higher burden may be targeted for this type of intervention, as they seemed to benefit the most.

Quality of life for caregivers of people with Alzheimer's disease

AIM

This paper is a report of a study to describe the meaning of quality of life for caregivers of patients with Alzheimer's disease and to identify factors that affect their quality of life.

BACKGROUND

The burden for informal caregivers and change in their quality of life can lead to patients being placed in nursing homes. Factors found to worsen caregivers' quality of life include strained finances, poor family functioning, difficult patient behaviour, financial burdens and the amount of time caregivers spend caring for family members with Alzheimer's disease.

METHOD

A hermeneutic phenomenological design was used to study 32 informal caregivers of patients with Alzheimer's disease. Data were collected using interviews between November 2004 and June 2005.

FINDINGS

Caregivers associated good quality of life with serenity, tranquility, psychological well-being, freedom, general well-being, good health and good financial status. Factors that caregivers said improved their quality of life were good health of the patient, independence from the patient, and more help in caregiving. Factors that worsened their quality of life were worries about the future and progression of the patient's illness and stress.

CONCLUSION

Our findings may help healthcare professionals have a deeper understanding of the meaning caregivers give to quality of life and thereby aid in the design of strategies to maintain or improve quality of life. Intervention research is needed for caregivers in countries where this has not yet been performed. Researchers should also investigate whether different types of caregivers (spouse, adult child and friend) have different needs or problems.
