Cognitive, functional and behavioral factors associated with the burden of caring for geriatric patients with cognitive impairment or depression: evidence from a South American sample

Self-Assessment Instruments for Supporting Family Caregivers: An Integrative Review

Family caregivers take on a variety of tasks when caring for relatives in need of care. Depending on the situation and the intensity of care, they may experience multidimensional burdens, such as physical, psychological, social, or financial stress. The aim of the present study was to identify and appraise self-assessment instruments (SAIs) that capture the dimensions of family caregivers' burdens and that support family caregivers in easily identifying their caregiving role, activities, burden, and needs. We performed an integrative review with a broad-based strategy. A literature search was conducted on PubMed, Google Scholar, Google, and mobile app stores in March 2020. After screening the records based on the eligibility criteria, we appraised the tools we found for their usefulness for family care and nursing practice. From a total of 2654 hits, 45 suitable SAIs from 274 records were identified and analyzed in this way. Finally, nine SAIs were identified and analyzed in detail based on further criteria such as their psychometric properties, advantages, and disadvantages. They are presented in multi-page vignettes with additional information for healthcare professionals. These SAIs have proven useful in assessing the dimensions of caregiver burden and can be recommended for application in family care and nursing practice.

A Systematic Review and Meta-Analysis of Dyadic Psychological Interventions for BPSD, Quality of Life and/or Caregiver Burden in Dementia or MCI

Objectives: This systematic review and meta-analysis assesses the effectiveness of psychological interventions that involve people with dementia or mild cognitive impairment (MCI) and their informal caregivers, and target improvements in the management of the behavioral and psychological symptoms of dementia (BPSD); quality of life; and/or burden reduction for people with either dementia or MCI and their informal caregivers.Methods: Studies were identified through database searches (Cochrane Library, CENTRAL, CINAHL, EMBASE, MEDLINE and PsychINFO) and clinical trials registers (ClinicalTrials.gov and http://apps.who.int/trialsearch/). Data were pooled for meta-analysis.Results: Database and reference list searches identified 1,878 references, of which fourteen studies were included. Positive effects were found on the anxiety symptoms of people with dementia on the RAID scale; on the quality of life of people with dementia on the self-rated QoL-AD scale; and on informal caregiver burden on the Zarit Burden Interview.Conclusions: Psychological interventions involving whole dyads have some promise for both people with dementia and informal caregivers, but are still far from uniformly effective across BPSD, quality of life, and caregiver burden. Further research directions are discussed.Clinical Implications: The results suggest that clinicians should routinely involve both halves of the dyad when delivering psychological interventions targeting anxiety or quality of life for people with dementia, or burden for informal caregivers.

Development of a Thai tool for assessing behavioral and psychological symptoms of dementia: A confirmatory factor analysis

INTRODUCTION

The early recognition and management of the behavioral and psychological symptoms of dementia (BPSD) are important to inform treatment decisions. Current BPSD screening tools are time-consuming and require advanced skills, limiting their application in routine clinical practice. An easier and quicker tool for use by nonphysician healthcare personnel is needed.

METHODS

A 14-item, Thai-language, BPSD scoring system for dementia (BPSD-T) was developed, based on clinical surveys and modifications after a pilot study. The Neuropsychiatric Inventory (NPI), BPSD-T, Thai Mental State Examination (TMSE), Clinical Dementia Rating Scale (CDR), and Barthel Index were performed. BPSD-T and NPI scores were compared, and test validity and reliability were analyzed.

RESULTS

A total of 168 people with dementia (mean age, 80.7 ± 6.7 years) and their primary caregivers were recruited. A total of 105 (62.5%) subjects were diagnosed with Alzheimer's disease (AD), and 31 (18.5%) with AD with small-vessel disease. The Global CDR was 0.5-1 for 73.8% of subjects, and 2-3 for 26.2%. The BPSD-T content validity index was 0.80-0.98, with high inter-rater and test-retest reliability. Confirmatory factor analysis showed the goodness of fit of 5 clusters of BPSD-T included a psychomotor syndrome (aggression, irritability, delusions, insomnia), an affective syndrome (apathy, repeating, anxiety, depression), a psychosis syndrome (misidentification, hallucinations), a behavior syndrome (hoarding, rummaging, wandering), and a euphoria syndrome (euphoria). Convergent validity showed a high correlation of the frequency score (r = 0.66) and caregiver distress score (r = 0.76) with the NPI. The BPSD-T score was significantly higher with more severe dementia. The average completion time for the BPSD-T (230.9 ± 65.5 s) was significantly less than that for NPI (506 ± 196.9 s; p < .001).

CONCLUSIONS

BPSD-T is a quick, reliable, and valid test to evaluate BPSD from the common dementia subtypes and severity, with a good correlation with the NPI. Its application in routine clinical practice will enable earlier recognition, targeted intervention, improved quality of care, and reduced caregiver burden.

Behavioural intervention to reduce disruptive behaviours in adult day care centres users: A randomizsed clinical trial (PROCENDIAS study)

AIM

This study assesses the effect of an intervention to reduce the disruptive behaviours (DB) presented by care recipient users of adult day care centres (ADCC), thereby reducing caregiver overload. While ADCC offer beneficial respite for family caregivers, the DB that many care recipients show promote resistance to attending these centres, which can be a great burden on their family caregivers.

DESIGN

Randomized controlled clinical trial.

METHODS

The study was carried out with 130 family caregivers of people attending seven ADCC in the municipality of Salamanca (Spain), randomly distributed into intervention and control groups. The intervention was applied across eight sessions, one per week, in groups of 8-10 people where caregivers were trained in the Antecedent-Behavior-Consequence (ABC) model of functional behaviour analysis. The primary outcome was the reduction of DB measured with the Revised Memory and Behavior Problems Checklist (RMBPC).

RESULTS

An average reduction in the RMBPC of 4.34 points was obtained in the intervention group after applying the intervention (p < 0.01 (U de Mann-Whitney); Cohen d = 1.00); furthermore, differences were found in the Center for Epidemiologic Studies Depression Scale (CES-D) (U = -2.67; p = 0.008; Cohen d = 0.50) and in the Short Zarit Burden Interview (Short ZBI) (t = -4.10; p < 0.01; Cohen d = 0.98).

CONCLUSION

The results obtained suggest that the implementation of this intervention could reduce both the frequency of DB occurrence and the reaction of the caregiver to their appearance. Improvement was also noted in the results regarding overload and emotional state of the family caregiver.

IMPACT

To our knowledge, this is the first randomized clinical trial to show that an intervention based on the ABC model could reduce the frequency and reaction of DB of care recipients in ADCC increasing their quality of life, and improving the mental health and overload of their family caregivers.

Problem-solving therapy reduces subjective burden levels in caregivers of family members with mild cognitive impairment or early-stage dementia: Secondary analysis of a randomized clinical trial

OBJECTIVES

Interventions addressing burden have limited impact among long-term family caregivers. We examined whether problem-solving therapy (PST) would reduce burden levels of caregivers of individuals diagnosed with mild cognitive impairment (MCI) or early-stage dementia (AD).

METHODS

Caregivers (N = 73) randomly received PST or nutritional training (NT). Burden measures were assessed over 1-year post-intervention.

RESULTS

Relative to NT, caregivers receiving PST endorsed improved perceived burden levels over time, regardless of the type of caregiver. Distress over the care recipient's dementia-related behaviors remained low over time among MCI caregivers receiving PST, while these burden levels among MCI caregivers receiving NT rose over time. AD caregivers receiving PST endorsed reductions in these burden levels over time, while AD caregivers in the NT group endorsed higher burden levels over time.

CONCLUSION

PST, taught early in the caregiving trajectory, improves subjective burden levels among caregivers of family members with relatively mild cognitive deficits.

Exposure to ambient fine particles and neuropsychiatric symptoms in cognitive disorder: A repeated measure analysis from the CREDOS (Clinical Research Center for Dementia of South Korea) study

There is a growing concern that air pollution, especially those particles <2.5 μm (PM_2.5), could increase the risk of cognitive impairment and mental disorders. However, the relationship between ambient PM_2.5 and neuropsychiatric symptoms in people with cognitive impairment is still undetermined. This longitudinal study included 645 pairs of cognitively impaired subjects, who had not changed residence within Seoul, and their caregivers from the Clinical Research Center for Dementia of South Korea study cohort between September 2005 and June 2010 (1763 days). Neuropsychiatric symptoms were measured by the Korean version of the Neuropsychiatry Inventory, and caregiver burden was examined by the Neuropsychiatry Inventory Caregiver Distress Scale at the first and second visits at the outpatient clinic. District-specific PM_2.5 concentrations were constructed over 1 month to 1 year prior to each visit. A log-linear regression using generalized estimating equations to account for repeated measures was used to assess the relationship between PM_2.5 exposure and neuropsychiatric symptoms or caregiver burden. Aggravated neuropsychiatric symptoms were associated with exposure to high PM_2.5 levels (adjusted percent change: 16.7% [95% confidence interval (CI), 5.0-29.7] per 8.3 μg/m³ increase in 1-month moving averages). Increased caregiver burden was associated with high PM_2.5 exposures only in caregivers for patients with Alzheimer's disease (adjusted percent change: 29.0% [95% CI, 8.1-53.9] per 8.3 μg/m³ increase in 1-month moving averages). The present results indicate that PM_2.5 exposure is associated with aggravated neuropsychiatric symptoms and increased caregiver burden in subjects with cognitive impairment. The findings in this study suggest that the role of air pollution deserves great consideration in the aging population with cognitive impairment.

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.

Anxiety and depression symptoms among caregivers of care-recipients with subjective cognitive decline and cognitive impairment

Background

Caregivers of care-recipients with mild cognitive impairment (MCI) or dementia experience high caregiver burden; however, the psychiatric burden of caregivers of care-recipients with subjective cognitive decline (SCD) has not been investigated. We aimed to explore the prevalence of and risk factors for anxiety and depression symptoms among the caregivers of care-recipients with SCD and cognitive impairment.

Methods

The Hospital Anxiety and Depression Scale (HADS) was used to examine the anxiety and depression symptoms among the caregivers of 343 care-recipients (84 with SCD, 120 with MCI and 139 with dementia) treated at the Memory Clinic of Huashan Hospital in Shanghai, China from May 2012 to October 2014. A logistic regression was used to explore the factors associated with caregiver’s anxiety and depression symptoms.

Results

In total, 26.5 % of caregivers had anxiety symptoms, and 22.4 % had depression symptoms. Totals of 17.9, 30.0 and 28.8 % of caregivers of care-recipients with SCD, MCI or dementia, respectively, had anxiety symptoms (P = 0.1140), whereas 22.6, 24.2 and 20.9 %, respectively, had depression symptoms (P = 0.8165). The risk factors for caregiver’s anxiety symptoms were increased caregiver age as well as having care-recipients who were male, had higher Cohen Mansfield Agitation Inventory (CMAI) scores, and higher Geriatric Depression Scale (GDS) scores. The risk factors for caregiver’s depression symptoms were increased caregiver age as well as caring for care-recipients with MCI or SCD, those with lower Toronto Empathy Questionnaire (TEQ) scores, and those with higher GDS scores.

Conclusions

Caregivers of care-recipients with SCD showed the same level of depression symptoms as those of care-recipients with MCI. Caregiver’s depression and anxiety symptoms were associated with their care-recipients’ psychiatric and behavioral syndromes.

Caregiving in Dementia and its Impact on Psychological Functioning and Health-Related Quality of Life: Findings from a Colombian Sample

Existing published studies about health-related quality of life (HRQOL) in caregivers of dementia patients living in Latin American countries are very limited. However, cultural aspects, personal values, and social structure may affect the way caregivers experience their role in different societies. The current study investigated the relationship between HRQOL and psychological factors using a cross-sectional design. The sample consisted of 102 informal caregivers of patients with dementia from Bogotá, Colombia, South America. Measures included the Patient Health Questionnaire (PHQ-9) for depression, the Satisfaction with Life Scale (SWLS), the Zarit Burden Interview, and the Short Health Questionnaire (SF36) for HRQOL. Canonical correlations revealed that there was a significant relationship between caregivers' mental health and HRQOL, such that caregivers with better satisfaction with life and less symptoms of depression had more vitality and better general health. There is a strong relationship between mental health and health-related quality of life in Colombian caregivers of dementia patients living in their country of origin. Specific aspects of mental health, including satisfaction with life and depression, need to be addressed in order to improve caregivers' quality of life. Given that mental health care resources may be scarce in Latin American countries, culturally appropriate interventions should focus on preventing/treating depression and promote life satisfaction, as a way to improve their quality of life.

Measuring the impact of informal elderly caregiving: a systematic review of tools

PURPOSE

To classify and identify the main characteristics of the tools used in practice to assess the impact of elderly caregiving on the informal carers' life.

METHODS

A systematic review of literature was performed searching in Embase, MEDLINE, PsycINFO, CINAHL, IBECS, LILACS, SiiS, SSCI and Cochrane Library from 2009 to 2013 in English, Spanish, Portuguese and French, and in reference lists of included papers.

RESULTS

The review included 79 studies, among them several in languages other than English. Their inclusion increased the variety of identified tools to measure this impact (n = 93) and allowed a wider analysis of their geographical use. While confirming their overlapping nature, instruments were classified according to the degree of integration of dimensions they evaluated and their specificity to the caregiving process: caregiver burden (n = 20), quality of life and well-being (n = 11), management and coping (n = 21), emotional and mental health (n = 29), psychosocial impact (n = 10), physical health and healthy habits (n = 2), and other measures. A high use in practice of tools not validated yet and not caregiver-specific was identified.

CONCLUSIONS

The great variety and characteristics of instruments identified in this review confirm the complexity and multidimensionality of the effects of elderly caregiving on the informal carer's life and explain the difficulties to assess these effects in practice. According to the classification provided, caregiver burden and emotional and mental health are the most evaluated dimensions. However, further work is required to develop integrated and caregiving focused procedures that can appraise this complexity across different countries and cultures.

Caregiver burden characterization in patients with Alzheimer's disease or vascular dementia

OBJECTIVE

To characterize the differences of caregiver burden in patients with Alzheimer's disease (AD) and vascular dementia (VaD) in order to improve the care counselling and management plan.

METHODS

We included 506 patients consecutively attending the Alzheimer's Evaluation Unit of a Geriatric Unit, evaluated with Mini Mental State Examination (MMSE), Clinical Dementia Rating (CDR), Hamilton Rating Scale for Depression, and Neuropsychiatric Inventory. To all caregivers were administered the Caregiver Burden Inventory (CBI), a 24-item multidimensional questionnaire in which 5 subscales explore 5 dimensions of caregiver burden: (1) CBI-Objective; (2) CBI-Developmental; (3) CBI-Physical; (4) CBI-Social; and (5) CBI-Emotional.

RESULTS

The present study included, respectively, 253 AD patients and 253 VaD patients. AD patients at baseline showed a significantly higher instruction level (p < .0001), higher grade of cognitive impairment (MMSE, p < .0001), and increased severity stage of dementia (CDR, p < .0001) than VaD patients. AD caregivers, mainly females (p = 0.010), devoted significantly more length of time care (in months, p = 0.010) and time of daily care (in hours, p = 0.011) and showed a significantly higher burden level in CBI-Objective (p = 0.047), CBI-Physical (p < .0001), CBI-Social (p = 0.003), CBI-Emotional (p < .0001), and CBI-total score (p < .0001), than VaD caregivers. In both caregiver groups, a higher presence of spouses and sons (p < .0001) compared to other relatives was observed. AD caregiver burden showed a significant association with sex of caregivers and length of time care in months.

CONCLUSIONS

AD caregivers showed a higher burden level than VaD caregivers, and this appeared to be associated with sex and length of time care.

Patient-Reported Outcomes in Latin America: Implementation in Research and Role in Emerging HTA Systems

BACKGROUND

Patient-reported outcomes (PROs) are increasingly used to demonstrate the value of interventions and support health technology assessment (HTA).

OBJECTIVE

The objective of this work was to analyze trends regarding PROs in Latin America (LatAm), highlight challenges in the application of PROs in this region, and suggest solutions.

METHODS

A team of researchers with expertise in PROs conducted a nonsystematic PubMed literature search pertaining to the use of PROs in LatAm. The experts also drew on their experience working with PROs to assess the application of PROs in LatAm.

RESULTS

The literature search yielded more than 4000 publications, with an increasing publication rate in recent years. PROs are being used in LatAm in various study types: instrument validation, phase III international clinical trials, health service research. A large Inter-American Development Bank study demonstrates the growing importance of PROs in the region. The growth in local value sets for the EuroQol five-dimensional questionnaire in LatAm reflects the regional emergence of HTA systems. Operational challenges relate to ensuring the use of good-quality questionnaires that, at a minimum, have undergone appropriate cultural adaptation and ideally have established psychometric properties.

CONCLUSIONS

PROs are increasingly important in LatAm. Future efforts should aim to strengthen the operational and research infrastructure around PROs in the region. Innovation should be encouraged, including studying alternative methods of eliciting health utilities for economic evaluation. A wider scope around PRO uses for decision making by HTA bodies is an international trend with potential positive prospects in LatAm.

The effect of coping on the burden in family carers of persons with dementia

OBJECTIVES

This study explores the association between coping, measured by the extent of locus of control, and the burden of care on family carers of persons with dementia (PWD).

METHOD

Two hundred thirty PWD living at home and their family carers were recruited from 20 Norwegian municipalities. The carers' burden was assessed by the Relatives' Stress Scale (RSS) and coping by the Locus of Control Behaviour Scale. The PWD were assessed by the Neuropsychiatric Inventory (NPI-Q), the Physical Self-Maintenance Scale (PSMS), the Instrumental Activities of Daily Living (IADL) scale, and the Mini Mental Status Examination (MMSE).

RESULTS

Locus of control (LoC) was found to be the most important factor associated with the burden on carers of PWD, even when we had controlled for the PWD variables, such as the NPI-Q score. The LoC and the carer's use of hours per day to assist the PWD were the only two variables the carers found that affected the extent of the burden. The NPI-Q was the most important variable in the PWD that affected the burden on the carers.

CONCLUSION

Carers who believe that what happens to them is the consequence of their own actions are likely to be less burdened than carers not expecting to have control. This finding gives a possibility to identify carers with a high risk of burden.

Behavioral symptoms related to cognitive impairment

Neuropsychiatric symptoms (NPS) are core features of Alzheimer's disease and related dementias. On one hand, behavioral symptoms in patients with mild cognitive impairment (MCI) can indicate an increased risk of progressing to dementia. On the other hand, mild behavioral impairment (MBI) in patients who usually have normal cognition indicates an increased risk of developing dementia. Whatever the cause, all dementias carry a high rate of NPI. These symptoms can be observed at any stage of the disease, may fluctuate over its course, are a leading cause of stress and overload for caregivers, and increase rates of hospitalization and early institutionalization for patients with dementia. The clinician should be able to promptly recognize NPI through the use of instruments capable of measuring their frequency and severity to support diagnosis, and to help monitor the treatment of behavioral symptoms. The aims of this review are to describe and update the construct 'MBI' and to revise the reported NPS related to prodromal stages of dementia (MCI and MBI) and dementia stages of Alzheimer's disease and frontotemporal lobar degeneration.

Sense of coherence, burden, and affective symptoms in family carers of people with dementia

BACKGROUND

Caring for a relative with dementia has been associated with high levels of psychological morbidity in carers. Sense of coherence is an important resource of successful coping with caregiving. The purpose of the present study was to examine the relationship between stress associated with caregiving, sense of coherence, and self-reported depression and anxiety in family carers of people with dementia. We hypothesized that carers reporting high levels of anxiety and depression will report low levels of coherence, and that the relationship between caregiver stress and affective symptoms will be mediated by sense of coherence.

METHODS

A total of 170 carers of people with dementia took part in the present study. Family carers completed the Sense of Coherence Scale, the Relative Stress Scale, and the Hospital Anxiety and Depression Scale. A series of multiple linear regressions were conducted to examine the relationship between stress related to caregiving, caregiver anxiety and depression, and whether sense of coherence mediated this relationship.

RESULTS

Self-reported anxiety and depression were associated with low levels of sense of coherence. Sense of coherence mediated the relationship between burden and self-reported depressive effect and anxiety symptoms.

CONCLUSIONS

Carers reporting high levels of anxiety and depression are more likely to report low levels of sense of coherence. The relationship between stress related to caregiving and depressive symptoms is mediated by carers' self-reported sense of coherence. Future psychotherapeutic intervention studies in family carers of people with dementia may incorporate strategies that specifically target sense of coherence.

Comparison of the burdens of family caregivers and foreign paid caregivers of the individuals with dementia

BACKGROUND

The caregiver burden on foreign paid caregivers (FPCs) is currently not well understood. This study identified predictors and differences in caregiver burden between FPCs and family caregivers who provided care for patients with dementia.

METHODS

We recruited 489 patients with dementia (diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders, 4th edition) and used the Neuropsychiatric Inventory (NPI) and Clinical Dementia Rating (CDR) Scale to assess their neuropsychiatric behavioral problems and severity of dementia. All caregivers [FPCs (n = 42) and family caregivers with (n = 42) and without (n = 447) FPCs] completed three questionnaires: the Zarit Burden Interview (ZBI), the Center for Epidemiological Studies-Depression Scale (CES-D), and caregivers' knowledge of dementia (KD). To understand caregiver burden, we analyzed the correlations between ZBI and other variables and investigated the differences between family caregivers and FPCs.

RESULTS

NPI and CDR scores were higher among patients assisted by FPCs than among those whose families did not employ FPCs. Burdens were greater among family caregivers assisted by FPCs than among FPCs and family caregivers who were not assisted by FPCs. Family caregivers had greater knowledge of dementia than did FPCs. For family caregivers, CES-D scores (Spearman's r = 0.650; p < 0.01) and patients' NPI scores (Spearman's r = 0.471; p < 0.01) were correlated with caregiver burden. For FPCs, only CES-D scores (Spearman's r = 0.511; p < 0.01) were correlated with caregiver burden. A linear regression model showed that CES-D scores contributed most to caregiver burden in all groups [β = 0.560 (family caregivers without FPCs), 0.546 (family caregivers with FPCs), and 0.583 (FPCs); p < 0.005].

CONCLUSION

Both family caregivers and FPCs need emotional support. Adequate treatment to reduce the neuropsychiatric symptoms of patients with dementia might reduce the burden on family caregivers.

Strain and its correlates among carers of people with dementia in low-income and middle-income countries. A 10/66 Dementia Research Group population-based survey

OBJECTIVES

In a multi-site population-based study in several middle-income countries, we aimed to investigate relative contributions of care arrangements and characteristics of carers and care recipients to strain among carers of people with dementia. Based on previous research, hypotheses focused on carer sex, care inputs, behavioural and psychological symptoms (BPSD) and socioeconomic status, together with potential buffering effects of informal support and employing paid carers.

METHODS

In population-based catchment area surveys in 11 sites in Latin America, India and China, we analysed data collected from people with dementia and care needs, and their carers. Carer strain was assessed with the Zarit Burden Interview.

RESULTS

With 673 care recipient/carer dyads interviewed (99% of those eligible), mean Zarit Burden Interview scores ranged between 17.1 and 27.9 by site. Women carers reported more strain than men. The most substantial correlates of carer strain were primary stressors BPSD, dementia severity, needs for care and time spent caring. Socioeconomic status was not associated with carer strain. Those cutting back on work experienced higher strain. There was tentative evidence for a protective effect of having additional informal or paid support.

CONCLUSIONS

Our findings underline the global impact of caring for a person with dementia and support the need for scaling up carer support, education and training. That giving up work to care was prevalent and associated with substantial increased strain emphasizes the economic impact of caring on the household. Carer benefits, disability benefits for people with dementia and respite care should all be considered.

Factors influencing caregivers' burden among family caregivers and institutionalization of in-home elderly people cared for by family caregivers

OBJECTIVES

The purpose of this study was to determine the factors related to changes in the burden of caregivers who look after the elderly at home, as well as factors related to the institutionalization of the elderly who require care. The types of care services associated with reducing caregivers' burden and continuing in-home care were also studied.

METHODS

The study subjects were adults aged ≥65 years who used the services of in-home care management centres located in Osaka Prefecture, Japan, and their caregivers. This 2-year longitudinal study began in October 2007, with a total of three surveys undertaken once a year. The survey methods included self-administered questionnaires and the review of clinical records.

RESULTS

Dementia and its accompanying behavioural disturbances were found to be significantly related to the increased burden of caregivers and the institutionalization of those requiring care. A significantly higher proportion of caregivers with an increasing burden or those who maintained a high level of burden used day care services compared to those in the other groups.

CONCLUSION

Preventive intervention against dementia and its accompanying behavioural disturbances should be considered in the day care service to reduce caregivers' burden and to decrease institutionalization.

Cognitive reframing for carers of people with dementia

BACKGROUND

The balance of evidence about whether psychosocial interventions for caregivers of people with dementia could reduce carers' psychological morbidity and delay their relatives' institutionalisation is now widely regarded as moderately positive (Brodaty 2003; Spijker 2008). Multi-component, tailor-made psychosocial interventions are considered to be particularly promising (Brodaty 2003; Spijker 2008). These interventions involve multiple mechanisms of action. In this review we focused solely on the effectiveness of one element within psychosocial interventions, cognitive reframing. Cognitive reframing is a component of cognitive behavioral therapy (CBT). In dementia care, cognitive reframing interventions focus on family carers' maladaptive, self-defeating or distressing cognitions about their relatives' behaviors and about their own performance in the caring role.

OBJECTIVES

The objective of this review was to evaluate the effectiveness of cognitive reframing interventions for family carers of people with dementia on their psychological morbidity and stress.

SEARCH METHODS

The trials were identified by searching (5 April 2009) the Cochrane Dementia and Cognitive Improvement Group Specialized Register, which contains records from major healthcare databases: The Cochrane Library, MEDLINE, EMBASE, PsycINFO, CINAHL and LILACS, ongoing trial databases and grey literature sources. For more detailed information on what the Group's specialized register contains and to view the search strategies see the Cochrane Dementia and Cognitive Improvement Group methods used in reviews.The Cochrane Library, MEDLINE, EMBASE, PsycINFO, CINAHL, LILACS and a number of trial registers and grey literature sources were also searched separately on 5 April 2009.

SELECTION CRITERIA

Randomised controlled trials of cognitive reframing interventions for family carers of people with dementia.

DATA COLLECTION AND ANALYSIS

Three assessors (MVD, ID, JmC) independently judged whether the intervention being studied was documented in a trial; two assessors assessed trial quality.

MAIN RESULTS

Pooled data indicated a beneficial effect of cognitive reframing interventions on carers' psychological morbidity, specifically anxiety (standardised mean difference (SMD) -0.21; 95% confidence interval (CI) -0.39 to -0.04), depression (SMD -0.66; 95% CI -1.27 to -0.05), and subjective stress (SMD -0.23; 95% CI -0.43 to -0.04). No effects were found for carers' coping, appraisal of the burden, reactions to their relatives' behaviors, or institutionalization of the person with dementia.

AUTHORS' CONCLUSIONS

Cognitive reframing for family carers of people with dementia seems to reduce psychological morbidity and subjective stress but without altering appraisals of coping or burden. The results suggest that it may be an effective component of individualised, multi-component interventions for carers. Identifying studies with relevant interventions was a challenge for this review. The impact of cognitive reframing might be higher when used alongside other interventions because this offers better opportunities to tailor cognitive reframing to actual everyday carer problems.

Clinical manifestations of geriatric depression in a memory clinic: toward a proposed subtyping of geriatric depression

BACKGROUND

As the older population increases so does the number of older psychiatric patients. Elderly psychiatric patients manifest certain specific and unique characteristics. Different subtypes of depressive syndromes exist in late-life depression, and many of these are associated with cognitive impairment.

MATERIALS AND METHODS

A total of 109 depressive patients and 30 normal subjects matched by age and educational level were evaluated using a neuropsychiatric interview and an extensive neuropsychological battery. Depressive patients were classified into four different groups by SCAN 2.1 (schedules for clinical assessment in Neuropsychiatry): major depression disorder (n: 34), dysthymia disorder (n: 29), subsyndromal depression (n: 28), and depression due to mild dementia of Alzheimer's type (n: 18).

RESULTS

We found significant associations (p<.05) between depressive status and demographic or clinical factors that include marital status (OR: 3.4, CI: 1.2-9.6), level of daily activity (OR: 5.3, CI: 2-14), heart disease (OR: 12.5, CI: 1.6-96.3), and high blood cholesterol levels (p:.032). Neuropsychological differences were observed among the four depressive groups and also between depressive patients and controls. Significant differences were observed in daily life activities and caregivers' burden between depressive patients and normal subjects.

CONCLUSION

Geriatric depression is associated with heart disease, high cholesterol blood levels, marital status, and daily inactivity. Different subtypes of geriatric depression have particular clinical features, such as cognitive profiles, daily life activities, and caregivers' burden, that can help to differentiate among them.

LIMITATIONS

The cohort referred to a memory clinic with memory complaints is a biased sample, and the results cannot be generalized to other non-memory symptomatic cohorts.

Insurance status and demographic and clinical factors associated with pharmacologic treatment of depression: associations in a cohort in Buenos Aires

OBJECTIVE

There is a paucity of evidence about insurance status and the likelihood of receiving medical services in Latin America. The objective of this analysis was to examine the association between insurance status and pharmacologic treatment for depression.

METHODS

Patients referred to a memory clinic of a public hospital in Buenos Aires, Argentina, and identified with any of four types of depression (subsyndromal, dysthymia, major, and due to dementia) were included. Age, years of education, insurance status, Beck Depression Inventory score, and number of comorbidities were considered. Associations between these factors and not receiving pharmacologic treatment for depression were examined with logistic regression. Use of prescription neuroleptics, hypnotics, and anticholinesterase inhibitors was also explored.

RESULTS

Out of 100 patients, 92 with insurance status data were used. Sixty-one patients (66%) had formal insurance and 31 patients (34%) lacked insurance. Twenty-seven (44%) insured patients and 23 (74%) uninsured patients did not receive antidepressants (P = 0.001). Controlling for other factors, uninsured patients had 7.12 higher odds of not receiving treatment compared to insured patients (95% confidence interval 1.88-28.86). Older patients and those with more comorbidities had higher odds of not receiving treatment. More educated patients, those with higher Beck Depression Inventory score, and those without subsyndromal depression had lower odds of not receiving treatment. None of those associations were statistically significant.

CONCLUSIONS

These results suggest a potential negative effect of the lack of formal insurance regarding pharmacologic treatment for depression. These findings should be confirmed with larger samples, and for other diseases.
