Stress and depression in informal family caregivers of patients with Alzheimer’s disease

The impact of caregiving for children with chronic conditions on the HPA axis: A scoping review

Caregiving has been robustly linked to caregiver health through the dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis in the context of caregiving for an adult with a chronic illness. However, little research examines the physiological impact of caregiving for a child with a chronic illness despite high burden and unique stressors. In this review, we explore the links of caregiving for a child with a congenital, chromosomal, or genetic disorder to the regulation or dysregulation of the HPA axis. A search was conducted in PubMed, Embase, and the Web of Science and 15 studies met inclusion criteria. Overall, there were inconsistent links of caregiving to HPA axis functioning, perhaps due to the heterogeneity across disease contexts, study designs, and biomarker measurement. Future research should standardize measurement and study designs, increase participant diversity, and examine moderators of the links of caregiving to the HPA axis.

Mindfulness and Care Experience in Family Caregivers of Persons Living with Dementia

Background

Greater mindfulness, the practice of awareness and living in the moment without judgement, has been linked to positive caregiving outcomes in dementia caregivers and its impact attributed to greater decentering and emotion regulation abilities. Whether the impact of these mindfulness-based processes varies across caregiver subgroups is unclear.

Objective

Analyze cross-sectional associations between mindfulness and caregiver psychosocial outcomes, considering different caregiver and patient characteristics.

Methods

A total of 128 family caregivers of persons living with Alzheimer's disease and related disorders were assessed on several mindfulness measures (i.e., global; decentering, positive emotion regulation, negative emotion regulation) and provided self-reported appraisals of caregiving experience; care preparedness; confidence, burden, and depression/anxiety. Bivariate relationships between mindfulness and caregiver outcomes were assessed with Pearson's correlations and stratified by caregiver (women versus men; spouse versus adult child) and patient (mild cognitive impairment (MCI) versus Dementia; AD versus dementia with Lewy bodies; low versus high symptom severity) characteristics.

Results

Greater mindfulness was associated with positive outcomes and inversely associated with negative outcomes. Stratification identified specific patterns of associations across caregiver groups. Significant correlations were found between all mindfulness measures and caregiving outcomes in male and MCI caregivers while the individual mindfulness component of positive emotion regulation was significantly correlated to outcomes in most caregiver groups.

Conclusion

Our findings support a link between caregiver mindfulness and improved caregiving outcomes and suggest directions of inquiry into whether the effectiveness of dementia caregiver-support interventions may be improved by targeting specific mindfulness processes or offering a more inclusive all-scope approach depending on individual caregiver or patient characteristics.

Biomarkers and Risk Assessment of Alzheimer's Disease in Low- and Middle-Income Countries

Dementia is a chronic syndrome which is common among the elderly and is associated with significant morbidity and mortality for patients and their caregivers. Alzheimer's disease (AD), the most common form of clinical dementia, is biologically characterized by the deposition of amyloid-β plaques and neurofibrillary tangles in the brain. The onset of AD begins decades before manifestation of symptoms and clinical diagnosis, underlining the need to shift from clinical diagnosis of AD to a more objective diagnosis using biomarkers. Having performed a literature search of original articles and reviews on PubMed and Google Scholar, we present this review detailing the existing biomarkers and risk assessment tools for AD. The prevalence of dementia in low- and middle-income countries (LMICs) is predicted to increase over the next couple of years. Thus, we aimed to identify potential biomarkers that may be appropriate for use in LMICs, considering the following factors: sensitivity, specificity, invasiveness, and affordability of the biomarkers. We also explored risk assessment tools and the potential use of artificial intelligence/machine learning solutions for diagnosing, assessing risks, and monitoring the progression of AD in low-resource settings. Routine use of AD biomarkers has yet to gain sufficient ground in clinical settings. Therefore, clinical diagnosis of AD will remain the mainstay in LMICs for the foreseeable future. Efforts should be made towards the development of low-cost, easily administered risk assessment tools to identify individuals who are at risk of AD in the population. We recommend that stakeholders invest in education, research and development targeted towards effective risk assessment and management.

A Systematic Review of Mindfulness-Based Interventions for Patients with Mild Cognitive Impairment or Dementia and Caregivers

The aim of this article was to systematically review the quality and efficacy of the current evidence for mindfulness-based interventions (MBIs) in patients with mild cognitive impairment (MCI), patients with dementia (PwD), and their caregivers. We identified 20 randomized controlled trials (RCTs) (11 for patients, 9 for caregivers) published in the last 15 years. Evidence suggested that MBIs are highly acceptable and credible treatments for patients with MCI, PwD and caregivers. Specifically, for PwD, the results indicated that the magnitude of post-treatment effects of MBIs are in the medium to large range for psychosocial outcomes, and in the small to medium range for cognitive functioning; however, treatment effects on dementia biomarkers were mixed, ranging from small to large, depending on the outcome measure. Findings also evidenced salutary effects of MBIs for caregivers of PwD, with post-treatment effects ranging from medium to large for caregiver stress and burden and large effects for quality of life, and mixed outcomes for cognitive functioning, with effects in the small to large range. However, confidence in these findings is relatively limited due to methodological limitations, especially in terms of poor consistency in intervention strategies, outcome measures, and other key criteria across studies. To better assess the value of MBIs for these populations and optimize treatment outcomes, we recommend further research with improved study methodology (e.g., multi-method assessment, universal criterion and outcome measures, use of active control groups, larger sample sizes, long-term follow-up) to replicate current findings and enhance our understanding of underlying treatment mechanisms of MBIs.

Attitudes, beliefs, and changing trends of cannabidiol (CBD) oil use among caregivers of individuals with Alzheimer's disease

OBJECTIVES

With the increasing popularity of CBD-based products, especially CBD oil, it is increasingly important to understand what motivates caregivers of individuals with Alzheimer's disease (AD) to use CBD oil as part of treatment. The purpose of this study was to identify the attitudes and beliefs of caregivers of individuals with AD toward CBD oil in Poland, to identify factors that might be associated with the decision to use CBD oil among caregivers, and to explore whether such a decision was discussed with a healthcare professional.

METHOD

A cross-sectional online survey was conducted in Poland. Participation in the study was entirely voluntary and completely anonymous. Caregivers (n = 73) were asked about their practices and attitudes regarding CBD oil.

RESULTS

The most common source of knowledge about CBD oil was an online support group for caregivers. The vast majority of caregivers found CBD to be effective in managing behavioral symptoms of AD and believed that healthcare professionals should offer CBD oil as a part of treatment. However, only 63 % (n = 46) reported consulting with their physician about using CBD oil. The study also demonstrated that some caregivers thought that CBD oil use was illegal in Poland and that their care-recipient may develop a dependence and withdrawal symptoms if they stopped using it.

CONCLUSIONS

The results of the study highlight the positive and negative perceptions among caregivers of people with AD. The study also emphasizes the importance of enhancing communication between caregivers and healthcare professionals to discuss the use of CBD oil in the treatment of individuals with AD.

Developing a new behavioral framework for dementia care partner resilience (CP-R): A mixed research synthesis

BACKGROUND AND OBJECTIVES

Caring for a person living with dementia requires resilience, the capacity to recover and grow from challenging situations. Despite the increasing interest in assessing and promoting resilience for dementia care partners, behaviors that indicate this attribute are not well known. The goal of this study is to synthesize the literature to identify resilience-related behaviors and develop a new framework for future validation and intervention research.

RESEARCH DESIGN AND METHODS

We searched English-language peer-reviewed articles (January 1991 - June 2019) reporting qualitative or quantitative descriptions of resilience-related behaviors among dementia care partners. Thematic analysis was used to categorize behaviors into domains, identify the relationships among them, and generate a thematic map.

RESULTS

Sixteen articles were identified according to predefined inclusion criteria. Four domains emerged: (1) problem-response behaviors (problem-solving, problem-distancing); (2) self-growth behaviors (self-care activities, spiritual-related activities, and developing and maintaining meaningful social relationships); (3) help-related behaviors (help-seeking and help-receiving), and (4) learning-related behaviors (learning from others and reflection). Definitions of each domain, identification of corresponding behaviors, and formulation of Care Partner Resilience (CP-R) behavioral framework were informed by this mixed research synthesis and other relevant literature.

DISCUSSION AND IMPLICATIONS

The CP-R framework emerged as a result of a new focus on identifying and cultivating strengths instead of evaluating strain and burden. It serves as a useful foundation for understanding the impact of specific behaviors on dementia care partner resilience. Once validated, this framework will inform the development of future measures, research, interventions, and policies for dementia care partners.

Burden, quality of life, anxiety, and depressive symptoms among caregivers of hemodialysis patients: The role of social support

OBJECTIVE

The purpose of this study was to determine how burden and quality of life predict anxiety and depressive symptoms among caregivers of hemodialysis patients. Social support was included in the model as a proposed moderator in the above relationships.

METHODS

This cross-sectional study involved 340 caregivers of chronic kidney patients undergoing hemodialysis. The setting was in Terengganu, Malaysia. The caregivers completed the measures of caregiving burden, quality of life, social support, and symptoms of anxiety and depression.

RESULTS

About 28.8% and 52.4% of caregivers showed clinically moderate levels of anxiety and depressive symptoms, respectively. Furthermore, 35.9% and 3.8% of them showed clinically high levels of anxiety and depressive symptoms, respectively. Analyses showed that general quality of life was a significant predictor of both anxiety and depressive symptoms. Burden and psychological domains of quality of life significantly predicted anxiety. In addition, a lack of social support was a determinant of depressive symptoms. Evidence suggested that social support moderated the burden-anxiety relationship. Specifically, caregivers with low levels of social support showed more elevated levels of anxiety symptoms when their burden was higher.

CONCLUSION

There is an urgent need for early detection to initiate prompt treatment in this population. The study provides some important insights into offering comprehensive intervention to help caregivers cope more effectively through the provision of sufficient social support to buffer the effects of caregiving burden and improve mental health.

Caregiver expressed emotion as mediator of the relationship between neuropsychiatric symptoms of dementia patients and caregiver mental health in Hong Kong

Objectives: Quality of life among Hong Kong's family dementia caregivers is a current heightened public health concern. This was one of the first East Asian studies to examine the role of family expressed emotion (EE) in the negative caregiver outcomes associated with dementia caregiving. EE comprises overinvolved and critical communications in families of people with mental illness. In this research, caregiver EE was evaluated as a mediator of the relationship between behavioral and psychological problems associated with dementia (BPSD) and negative caregiver outcomes.Method: Participants were 89 Hong Kong family caregivers (79% female, 84% married, 43% >50 years of age) of people with diagnosed dementia, recruited from elder day care centers. Caregivers completed the Neuropsychiatric Inventory (NPI), Cohen Mansfield Agitation Inventory (CMAI), Level of Expressed Emotion scale (LEE), Zarit Burden Interview, and Center for Epidemiological Studies Depression Scale (CES-D).Results: Agitation, delusions, hallucinations, aggression and irritability were BPSD most associated with caregiver burden and depression. EE significantly mediated the BPSD-negative caregiver outcome relationship. Among EE subscales, intrusiveness was significantly more common and less associated with negative caregiver outcomes. Caregiving hours, low family support, and religious nonaffiliation were associated with EE and poorer caregiver outcomes.Conclusions: The negative impact of BPSD on dementia caregivers in Hong Kong is influenced by EE. Higher scores on EE intrusiveness may be partly accounted for by filial piety, a strong sense of family responsibility characterized by high attentiveness to elderly family members. As EE is a potentially modifiable factor, interventions are considered.

Burden in Tunisian Family Caregivers of Older Patients with Schizophrenia Spectrum and Bipolar Disorders; Associations with Depression, Anxiety, Stress, and Quality of Life

BACKGROUND

There are very little data on the burden among caregivers of older adults with severe mental diseases. We aimed to assess the perceived burden among caregivers of family members with schizophrenia spectrum and bipolar disorders.

METHOD

A cross-sectional study was carried out with 52 older patients with schizophrenia spectrum and bipolar disorders and their family caregivers. Caregivers were assessed with the medical outcome survey short form (SF-36), the Zarit Burden Interview (ZBI) and the Depression Anxiety and Stress scales (DASS-21).

RESULTS

Caregivers' mental quality of life was impaired with an average mental score of 59.05. For a threshold value of 17, the level of perceived burden was considered as high for 42.3% of caregivers. After controlling for demographic variables (age and gender) and patients' health-related variables (level of dependency, comorbidities, age onset of illness, number of hospitalizations and duration of clinical remission), caregivers' levels of depression, stress, and SF-36 physical component significantly contributed to their perceived burden.

CONCLUSIONS

Certain modifiable risk factors play an inescapable role in increasing the level of burden among caregivers of older patients with serious mental illnesses.

CLINICAL IMPLICATIONS

Improving the quality of life and psychological well-being of family caregivers should be considered an integral part of treatment for serious mental illness in older adult patients.

Quality of life of family carers of persons with young-onset dementia: A Nordic two-year observational multicenter study

OBJECTIVES

To identify factors associated with QOL in carers of persons with young-onset Alzheimer's (AD) and frontotemporal dementia (FTD) and explore development in QOL over a two-year period.

METHODS

Eighty-eight family carers of community-dwelling people with young-onset AD (n = 50) and FTD (n = 38) recruited from Nordic memory clinics. Carer QOL was assessed using the Quality of Life-Alzheimer's Disease questionnaire. Carer burden was assessed by the Relatives' Stress scale and depressive symptoms by the Montgomery-Åsberg Depression Rating Scale. Factors associated with QOL in YOD and development in QOL over time were explored with growth mixture model trajectories and mixed model analyses.

RESULTS

We identified two carer groups of persons with YOD following trajectories with better (n = 53) versus poorer (n = 30) QOL. Carers who reported more burden at baseline had greater odds of belonging to the poorer QOL group (OR 1.1 (1.0-1.2), p = 0.004). Analyses of the development in QOL showed a significant decline in QOL-AD scores among the AD-carers from baseline to two-year follow-up (p = 0.044), while the score remained stable among the FTD-carers. The FTD-carer group had significantly higher mean QOL-AD scores at one- and two-year follow-up (p = 0.022 and 0.045, respectively). However, the difference between the two groups regarding time trend was non-significant. Poorer QOL was associated with increased carer burden (p = 0.01), more depressive symptoms (p = 0.024), and being male carer (p = 0.038).

CONCLUSION

Higher care burden, more depressive symptoms, and being a male carer was associated with poorer QOL in family carers for persons with YOD. Carers of persons with AD may experience greater challenges in preserving QOL compared to carers of persons with FTD.

Conditions of caring for the elderly and family caregiver stress in Chiang Mai, Thailand

Purpose

The family caregivers play an important role in the good quality of life for the elderly, but most of them can easily have an emotional and psychological effect on caregiving. The purpose of this paper is to explore the correlation between conditions of caring for the elderly in the family and caregiver stress in a community setting, Chiang Mai Province, Thailand.

Design/methodology/approach

A cross-sectional exploratory descriptive research was conducted in Ban Klang Subdistrict, San Pa Tong District, Chiang Mai Province. Simple random sampling was used to collect data by using a structured interview via a questionnaire with 103 elderly caregivers. The χ2 test was used to explain the conditions related to stress as being a caregiver.

Findings

Most of the caregivers were female and still in good health, but at the same time, underwent little stress. However, they did not receive any training beforehand for taking care of the elderly but mainly done by experience, relationship and gratitude. The conditions correlated with stress as being a caregiver were health status of caregivers, confidence of care, the relationship between caregiver and elderly person, and economic burden of care.

Originality/value

A necessary resource such as body of knowledge in elderly caregiving, long-term care system at the community level and social support from family and intimate persons will encourage confidence in taking care of the elderly in the family and also relieve caregivers’ stress.

Assessment of Caregiver Inventory for Rett Syndrome

Rett syndrome (RTT) requires total caregiver attention and leads to potential difficulties throughout life. The Caregiver Burden Inventory, designed for Alzheimer disease, was modified to a RTT Caregiver Inventory Assessment (RTT CIA). Reliability and face, construct, and concurrent validity were assessed in caregivers of individuals with RTT. Chi square or Fisher's exact test for categorical variables and t tests or Wilcoxon two-sample tests for continuous variables were utilized. Survey completed by 198 caregivers; 70 caregivers completed follow-up assessment. Exploratory factor analysis revealed good agreement for physical burden, emotional burden, and social burden. Internal reliability was high (Cronbach's alpha 0.898). RTT CIA represents a reliable and valid measure, providing a needed metric of caregiver burden in this disorder.

Implementación del programa de intervención psicológica en resiliencia para cuidadores informales de pacientes con demencia tipo Alzheimer PIRCA

Los programas de intervención psicológica de enfoque cognitivo conductual para cuidadores informales de pacientes con Alzheimer han sido hasta el momento los más utilizados por la efectividad de sus resultados. El objetivo de este estudio es la implementación del programa PIRCA (Programa de Intervención en Resiliencia para Cuidadores Informales de pacientes con Alzheimer) para observar los cambios presentados en los sujetos después de haber participado en el programa. Participaron 10 cuidadores informales, que no recibían remuneración, sin capacitación y convivían con el paciente. Se diseñó un estudio experimental transversal descriptivo comparativo, tipo pre-test/post-test. Los resultados indicaron que los puntajes de las variables con mayor variabilidad fueron depresión estado, eutimia estado, sobrecarga, y estrategias de afrontamiento como búsqueda de apoyo social y religión. Con lo que se concluye que intervenir la resiliencia responde a una necesidad básica de los cuidadores ya que está presente en las características de personalidad del cuidador

Virtually supportive: a feasibility pilot study of an online support group for dementia caregivers in a 3D virtual environment

INTRODUCTION

Caregiver support groups effectively reduce stress from caring for someone with dementia. These same demands can prevent participation in a group. The present feasibility study investigated a virtual online caregiver support group to bring the support group into the home. While online groups have been shown to be helpful, submissions to a message board (vs. live conversation) can feel impersonal.

METHOD

By using avatars, participants interacted via real-time chat in a virtual environment in an 8-week support group.

RESULT

Data indicated lower levels of perceived stress, depression and loneliness across participants. Importantly, satisfaction reports also indicate that caregivers overcame the barriers to participation, and had a strong sense of the group's presence.

DISCUSSION

This study provides the framework for an accessible and low cost online support group for a dementia caregiver. The study demonstrates the feasibility of interactive group in a virtual environment for engaging members in meaningful interaction.

Yogic meditation reverses NF-κB and IRF-related transcriptome dynamics in leukocytes of family dementia caregivers in a randomized controlled trial

BACKGROUND

Although yoga and meditation have been used for stress reduction with reported improvement in inflammation, little is known about the biological mechanisms mediating such effects. The present study examined if a yogic meditation might alter the activity of inflammatory and antiviral transcription control pathways that shape immune cell gene expression.

METHODS

Forty-five family dementia caregivers were randomized to either Kirtan Kriya Meditation (KKM) or Relaxing Music (RM) listening for 12 min daily for 8 weeks and 39 caregivers completed the study. Genome-wide transcriptional profiles were collected from peripheral blood leukocytes sampled at baseline and 8-week follow-up. Promoter-based bioinformatics analyses tested the hypothesis that observed transcriptional alterations were structured by reduced activity of the pro-inflammatory nuclear factor (NF)-κB family of transcription factors and increased activity of Interferon Response Factors (IRFs; i.e., reversal of patterns previously linked to stress).

RESULTS

In response to KKM treatment, 68 genes were found to be differentially expressed (19 up-regulated, 49 down-regulated) after adjusting for potentially confounded differences in sex, illness burden, and BMI. Up-regulated genes included immunoglobulin-related transcripts. Down-regulated transcripts included pro-inflammatory cytokines and activation-related immediate-early genes. Transcript origin analyses identified plasmacytoid dendritic cells and B lymphocytes as the primary cellular context of these transcriptional alterations (both p<.001). Promoter-based bioinformatic analysis implicated reduced NF-κB signaling and increased activity of IRF1 in structuring those effects (both p<.05).

CONCLUSION

A brief daily yogic meditation intervention may reverse the pattern of increased NF-κB-related transcription of pro-inflammatory cytokines and decreased IRF1-related transcription of innate antiviral response genes previously observed in healthy individuals confronting a significant life stressor.

Cyr N, Khalsa D, Lin J, Blackburn E, Epel E, Irwin MR. A pilot study of yogic meditation for family dementia caregivers with depressive symptoms: effects on mental health, cognition, and telomerase activity

BACKGROUND

This study examined the effects of brief daily yogic meditation on mental health, cognitive functioning, and immune cell telomerase activity in family dementia caregivers with mild depressive symptoms.

METHODS

Thirty-nine family dementia caregivers (mean age 60.3 years old (SD = 10.2)) were randomized to practicing Kirtan Kriya or listening to relaxation music for 12 min per day for 8 weeks. The severity of depressive symptoms, mental and cognitive functioning were assessed at baseline and follow-up. Telomerase activity in peripheral blood mononuclear cells (PMBC) was examined in peripheral PBMC pre-intervention and post-intervention.

RESULTS

The meditation group showed significantly lower levels of depressive symptoms and greater improvement in mental health and cognitive functioning compared with the relaxation group. In the meditation group, 65.2% showed 50% improvement on the Hamilton Depression Rating scale and 52% of the participants showed 50% improvement on the Mental Health Composite Summary score of the Short Form-36 scale compared with 31.2% and 19%, respectively, in the relaxation group (p < 0.05). The meditation group showed 43% improvement in telomerase activity compared with 3.7% in the relaxation group (p = 0.05).

CONCLUSION

This pilot study found that brief daily meditation practices by family dementia caregivers can lead to improved mental and cognitive functioning and lower levels of depressive symptoms. This improvement is accompanied by an increase in telomerase activity suggesting improvement in stress-induced cellular aging. These results need to be confirmed in a larger sample.

Caregiver burden after stroke: towards a structural model

BACKGROUND AND PURPOSE

Stroke may impose a severe burden on both the patients and their caregivers. Although there is substantial literature relating to the adverse impact of stroke on patients, considerably less is known about its impact on their caregivers. The aim of this study was to analyse predictive factors of the overall burden in caregivers of stroke victims and to verify the structural model of burden, built on the basis of theoretical and empirical assumptions.

MATERIAL AND METHODS

One hundred and fifty pairs of patients and their caregivers were evaluated. The Caregiver Burden Scale (CB), Hospital Anxiety and Depression Scale (HADS), Sense of Coherence Scale (SOC), Social Support Scale, Geriatric Depression Scale, Barthel Index and Scandinavian Stroke Scale were all used to evaluate caregiver burden and the characteristics of patients and caregivers.

RESULTS

The caregivers experienced a moderate burden (mean CB = 2.08) and emotional distress (mean total HADS = 14.1). Path analysis showed that higher burden was associated with a lower SOC score, higher emotional distress, and lower patient's functional status. Higher emotional distress, in turn, was associated with lower SOC and lower patient's functional status. These results show that the burden and the degree of emotional disturbance are two distinct negative consequences of caregiving.

CONCLUSIONS

The negative consequences of caregiving depend mainly on the caregiver's intra-psychic factors and the patient's disability. Professional interventions should be targeted at enhancing caregivers' ability to cope with stress, improving their caregiving skills and reducing the physical dependence of patients.

Improving depression and enhancing resilience in family dementia caregivers: a pilot randomized placebo-controlled trial of escitalopram

BACKGROUND

This study examined the potential of an antidepressant drug, escitalopram, to improve depression, resilience to stress, and quality of life in family dementia caregivers in a randomized placebo-controlled double-blinded trial.

METHODS

Forty family caregivers (43-91 years of age, 25 children and 15 spouses; 26 women) who were taking care of their relatives with Alzheimer disease were randomized to receive either escitalopram 10 mg/day or placebo for 12 weeks. Severity of depression, resilience, burden, distress, quality of life, and severity of care-recipient's cognitive and behavioral disturbances were assessed at baseline and over the course of the study. The Hamilton Depression Rating Scale scores at baseline ranged between 10 and 28. The groups were stratified by the diagnosis of major and minor depression.

RESULTS

Most outcomes favored escitalopram over placebo. The severity of depression improved, and the remission rate was greater with the drug compared with placebo. Measures of anxiety, resilience, burden, and distress improved on escitalopram compared with placebo.

DISCUSSION

Among caregivers, this small randomized controlled trial found that escitalopram use resulted in improvement in depression, resilience, burden and distress, and quality of life. Our results need to be confirmed in a larger sample.

Resilience and aging

This article summarizes the literature on resilience to stress and aging. Key concepts and definitions of resilience are identified, and psychosocial and biological factors contributing to resilience that are universal across ages, as well as those that are unique to aging, are reviewed. Current and potentially useful intervention approaches to promote resilience and wellbeing are also reviewed. Views on future directions in resilience research and interventions targeting resilience are offered.
