Age, gender, kinship and caregiver burden in amyotrophic lateral sclerosis

Is caregiver burden of patients with amyotrophic lateral sclerosis related to caregivers' mindfulness, quality of life, and patients' functional level

BACKGROUND AND OBJECTIVE

The aim of this study was to evaluate the caregiver burden, mindfulness, and quality of life (QoL) of caregivers of ALS patients and the patient's functional level.

METHODS

This study was conducted with 57 ALS patients and their primary caregivers. The data were collected using the Zarit Burden Interview, Mindful Attention Awareness Scale (MAAS), the Short Form-36 (SF-36), and the ALS Functional Rating Scale (ALS-FRS).

RESULTS

The mean age of the caregivers was 49.7 ± 12 years; 66 % were female, and 73.7 % were spouses of the patients. Around 65 % of caregivers experienced a moderate to severe caregiver burden. A low and negative correlation was found between the caregiver burden and mindfulness of caregivers of ALS patients. As the mindfulness levels of the caregivers increased, the caregiver burden decreased, and the physical role difficulty score, one of the sub-dimensions of the QoL, increased. Also, caregivers' QoL decreased as caregiver burden increased (except physical function QoL, p < 0.05). Moreover, there was a positive correlation between the caregiver burden and ALSFRS-R scores (bulbar, motor, respiratory, and total) of the caregivers of ALS patients (p < 0.05).

DISCUSSION

Improved technology for managing ALS disease has increased patient life expectancy. However, caregivers may experience a high burden as the patient's functional level declines. Increasing caregiver mindfulness can help reduce the burden and improve their QoL.

Relationship between Burden, Quality of Life and Difficulties of Informal Primary Caregivers in the Context of the COVID-19 Pandemic: Analysis of the Contributions of Public Policies

The study aimed to characterize and understand the difficulties experienced by informal caregivers from a bio-psychosocial and environmental perspective, taking into account the socio-demographic and health characteristics of the informal caregiver and the person cared for, quality of life, perceived burden, social support, and the impact of the COVID-19 pandemic on the informal caregiver and the person cared for. The participants were 371 informal primary caregivers, 80.9% female, aged between 25 and 85 years, mean 53.17 (SD = 11.45) years. Only 16.4% of the informal caregivers benefited from monitoring and training for informal caregiver skills; 34.8% received information on the rights of the person being cared for; 7.8% received advice or guidance on the rights and duties of the informal caregiver; 11.9% of the caregivers benefited from psychological support; and 5.7% participated in self-help groups. A convenience sample was used, and data were collected via an online questionnaire. The main findings show that the major difficulties experienced by caregivers are related to social constraints, the demands of caring, and the reactions of the person cared for. The results reveal that the burden of the main informal caregivers is explained by the level of education, quality of life, level of dependence of the person cared for, level of difficulties, and social support. The COVID-19 pandemic impacted caregiving by increasing the perceived difficulty of accessing support services, such as consultations, services, and support; causing distress feelings in the caregiver, such as, anxiety and worry; increasing the needs and symptoms of the person cared for; and increasing the degree of isolation, for both, the informal caregiver and the person cared for.

Care burden and related factors among informal caregivers of patients with amyotrophic lateral sclerosis

Objective: Amyotrophic lateral sclerosis (ALS) affects the life of the family caregiver as well as the patient. This study aimed to determine the care burden and related factors among family caregivers of Turkish ALS patients. Methods: This descriptive study was conducted with 108 ALS patients and their informal caregivers through face-to-face interviews at home. The data were collected using the ALS Functional Rating Scale, Zarit Burden Interview, European Quality of Life-Five Dimensions Questionnaire, Multidimensional Scale of Perceived Social Support, and the Hospital Anxiety and Depression Scale. Results: The mean age of the caregivers was 48.1 ± 13.4 years; the vast majority were female, and they were either spouses or children of the patients. While 49.1% reported moderate or severe burden, the quality of life was moderate (mean 70.4 ± 22.8). The caregiver burden was related to sex and the functional state of the patient, as well as caregiver factors such as the relation to the patient, sex, health status, time spent for care, and living in the same house with a limited environment. Walking ability, percutaneous endoscopic gastrostomy, tracheostomy, and communication problems were not associated with the burden. Furthermore, burden was associated with the caregiver's quality of life, social support, anxiety, and depression. Conclusions: The present study draws attention to the fact that the care burden in family caregivers of ALS patients is high and their quality of life is impaired. Our findings reveal that not only ALS patients but also caregivers need to be supported with an organized and planned system.

Support Needs and Interventions for Family Caregivers of Patients with Amyotrophic Lateral Sclerosis (ALS): A Narrative Review with Report of Telemedicine Experiences at the Time of COVID-19 Pandemic

Family caregivers of people with amyotrophic lateral sclerosis (ALS), a severely disabling neurodegenerative disease due to the degeneration of both upper and lower motor neurons, have a very demanding role in managing their relatives, thereby often experiencing heavy care burden. Previous literature has widely highlighted that this situation reduces caregivers’ quality of life and increases their psychological distress and risk of health problems, but there are relatively few studies that focus on psychological interventions for these situations. Family support is more—not less—important during crisis. However, during the COVID-19 pandemic, maintaining public safety has required restricting the physical presence of families for hospitalized patients. Caregivers of ALS patients felt increased sense of loneliness and experienced greater difficulties in the access to both hospital and home assistance. In response, health systems rapidly adapted family-centric procedures and tools to circumvent restrictions on physical presence. In this regard, internet-based and telehealth solutions have been adopted to facilitate the routine, predictable, and structured communication, crucial to family-centered care. This narrative review aims at addressing more current matters on support needs and interventions for improving wellbeing of caregivers of ALS patients. In particular, we aimed at highlighting several gaps related to the complex needs of caregivers of ALS patients, to the interventions carried out in order to respond to these needs, and to the changes that COVID-19 pandemic caused from 2020 to nowadays in clinical managing of ALS patients. Finally, we report ongoing experiences of psychological support for family caregivers of ALS patients through telehealth solutions, which have been reinforced in case of needing of physical distancing during the COVID-19 pandemic.

Caregiver burden and associated factors among primary caregivers of patients with ALS in home care: a cross-sectional survey study

OBJECTIVES

This study aims to understand the caregiver burden experienced by the primary caregivers of patients with amyotrophic lateral sclerosis (ALS), and to explore the factors influencing caregiver burden.

DESIGN

A cross-sectional survey design was used.

SETTING

This study was conducted with ALS inpatients and follow-up outpatients at the neurology department of a tertiary general hospital in Taiyuan, Shanxi, China and their caregivers.

PARTICIPANTS

Patients with ALS and their caregivers (N=120 pairs) participated in a face-to-face interview.

PRIMARY AND SECONDARY OUTCOME MEASURES

Primary outcome measures included the Zarit Burden Interview scores and personal/role burden scores. There were no secondary outcomes.

RESULTS

Multiple linear and logistic regression analyses were performed to examine the factors influencing burden in ALS patient's caregivers. Multiple linear regression showed that caregivers with higher Anxiety Index (AI) experienced greater personal (β=0.089, p<0.001), role (β=0.065, p<0.001) and overall (β=0.200, p<0.001) burden. Logistic regression analysis showed that AI (p=0.025; OR 1.351, 95% CI 1.038 to 1.759) and disease knowledge level (p=0.033; OR 0.305, 95% CI 0.107 to 0.593) are the influencing factors of ALS load classification.

CONCLUSIONS

Higher AI scores were associated with greater caregiver burden. Caregiver burden of caregivers who had no knowledge of the patient's disease was 0.305 times that of those who had good knowledge. The level of disease knowledge and AI score can serve as key predictors of caregiver burden in ALS.

Informal Caregiving in Amyotrophic Lateral Sclerosis (ALS): A High Caregiver Burden and Drastic Consequences on Caregivers' Lives

Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease that causes progressive autonomy loss and need for care. This does not only affect patients themselves, but also the patients’ informal caregivers (CGs) in their health, personal and professional lives. The big efforts of this multi-center study were not only to evaluate the caregivers’ burden and to identify its predictors, but it also should provide a specific understanding of the needs of ALS patients’ CGs and fill the gap of knowledge on their personal and work lives. Using standardized questionnaires, primary data from patients and their main informal CGs (n = 249) were collected. Patients’ functional status and disease severity were evaluated using the Barthel Index, the revised Amyotrophic Lateral Sclerosis Functional Rating Scale (ALSFRS-R) and the King’s Stages for ALS. The caregivers’ burden was recorded by the Zarit Burden Interview (ZBI). Comorbid anxiety and depression of caregivers were assessed by the Hospital Anxiety and Depression Scale. Additionally, the EuroQol Five Dimension Five Level Scale evaluated their health-related quality of life. The caregivers’ burden was high (mean ZBI = 26/88, 0 = no burden, ≥24 = highly burdened) and correlated with patients’ functional status (r_p = −0.555, p < 0.001, n = 242). It was influenced by the CGs’ own mental health issues due to caregiving (+11.36, 95% CI [6.84; 15.87], p < 0.001), patients’ wheelchair dependency (+9.30, 95% CI [5.94; 12.66], p < 0.001) and was interrelated with the CGs’ depression (r_p = 0.627, p < 0.001, n = 234), anxiety (r_p = 0.550, p < 0.001, n = 234), and poorer physical condition (r_p = −0.362, p < 0.001, n = 237). Moreover, female CGs showed symptoms of anxiety more often, which also correlated with the patients’ impairment in daily routine (r_s = −0.280, p < 0.001, n = 169). As increasing disease severity, along with decreasing autonomy, was the main predictor of caregiver burden and showed to create relevant (negative) implications on CGs’ lives, patient care and supportive therapies should address this issue. Moreover, in order to preserve the mental and physical health of the CGs, new concepts of care have to focus on both, on not only patients but also their CGs and gender-associated specific issues. As caregiving in ALS also significantly influences the socioeconomic status by restrictions in CGs’ work lives and income, and the main reported needs being lack of psychological support and a high bureaucracy, the situation of CGs needs more attention. Apart from their own multi-disciplinary medical and psychological care, more support in care and patient management issues is required.

Family Caregiver Suffering in Caring for Patients with Amyotrophic Lateral Sclerosis in Korea

The purpose of this study was to describe the meaning of the suffering experience of Korean ALS family caregivers. This is a descriptive phenomenological study that included ten participants using convenience sampling with maximum variation in a tertiary hospital in Seoul, South Korea. Colaizzi's data analysis method was used to inductively determine themes and formulate meanings. The three main themes derived from analysis were: "frustration with seeing a patient suffering", "burnout at the cost of a life of dedication", and "desperate need for help". Caregivers experience high levels of suffering, which can come in various forms depending on the circumstances of the particular patient and family. Especially, distress from seeing a loved one suffering was another aspect of suffering in Korean ALS caregivers, reflecting strong family ties. At the same time, patients are in desperate need of help and support from their families. Thus, it is essential to provide care to lessen the causes of distress and meet the needs of not only patients, but also caregivers through family-centered care to improve overall quality of life for all involved.

One Year Trajectory of Caregiver Burden in Parkinson's Disease and Analysis of Gender-Specific Aspects

Parkinson's disease (PD) is a slowly progressive neurodegenerative movement disorder that leads to impairments in activities of daily living. In addition to reducing patients' quality of life, this disease also affects caregivers' well-being. Until recently, caregiver burden was mainly assessed by generic questionnaires, which do not take the characteristics of the chronic disease into consideration. In the case of PD, this issue has been addressed by the introduction of the "Parkinson's disease caregiver burden" questionnaire (PDCB). Data on longitudinal trajectories of caregiver burden are still missing in the literature. In this study, we assessed the one-year trajectory of caregiver burden by the PDCB as a disease-specific questionnaire. Further, gender-specific aspects of caregiver burden were analyzed by applying a caregiver task questionnaire. PDCB total score (n = 84 patients and caregivers) did not significantly change from baseline (30.4) to one year at follow-up (31.5). No significant difference was detected between female and male caregivers in global burden and-specific caregiver tasks. Our data showed only a mild increase of caregiver burden in the timeframe of one year. Gender-specific differences do not seem to impact-specific caregiver tasks in the presented study population.

State of household need for caregivers and determinants of psychological burden among caregivers of older people in Thailand: An analysis from national surveys on older persons

OBJECTIVES

To explore the levels and trends of household need for caregivers of older people and to explore the impact of potential determinants of psychological burden among caregivers of older people in Thailand.

METHODS

The secondary data analysis was performed using the Survey of Older Persons in Thailand 2007, 2011, and 2014 datasets which conducted by the National Statistical Office of Thailand. The household need for caregivers of older persons refers to having at least one older person in the household who needs a caregiver for assistance with activities of daily living. Caregiver mental health, which is confined to the available 2011 data, is defined as a state of psychological burden. Ordinal logistic regression models were used to explore the impact of potential determinants of psychological caregiver burden.

RESULTS

The household need for caregivers in Thailand tends to be increasing, from 5.0% in 2007 to 6.6% in 2014. The levels of the household need for caregivers were significantly higher in urban areas, Bangkok, and high socioeconomic households. In terms of psychological caregiver burden, the Thai Mental Health Indicators in 2011 produced, on average, a fair level of mental health, but one-fourth of caregivers had poor mental health. Duration of care for older people, household wealth, and functional dependency significantly predict total caregiver burden. Household characteristics are vital in predicting psychological caregiver burden, and the adjusted effect of the fifth quintile of household wealth was high (odds ratio = 2.34; 95% confidence interval = 1.47-3.73).

CONCLUSION

The increasing need for caregiving in households with an older person can lead to a higher caregiver burden, particularly among those caregivers who care for dependent older people in poor households. Longer duration of caregiving is a factor that mitigates this burden.

Psychological distress in partners of patients with amyotrophic lateral sclerosis and progressive muscular atrophy: what's the role of care demands and perceived control?

Caregivers of Amyotrophic Lateral Sclerosis (ALS) and Progressive Muscular Atrophy (PMA) patients often experience psychological distress. Yet, it is unclear which factors explain the variance in psychological distress. This study seeks to evaluate how care demands and perceived control over caregiving influence psychological distress using moderation and mediation analysis. Data were collected as part of a RCT and 148 partners of patients with ALS or PMA were included. Psychological distress was assessed using the Hospital Anxiety and Depression Scale. Care demands were operationalized as physical functioning (Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised) and behavioural changes of the patient (Amyotrophic Lateral Sclerosis-Frontotemporal Dementia-Questionnaire). Perceived control over caregiving was assessed using items adapted from the Job Content Questionnaire. Results showed that more behavioural changes and lower perceived control over caregiving were associated with higher levels of psychological distress in caregivers. Patients' physical functioning was not significantly related to caregivers' psychological distress. No moderation or mediation effects were found of perceived control over caregiving on the relationship between demand and psychological distress. Monitoring, psychoeducation and caregiver support with regard to behavioural changes in patients, seem to be important for the wellbeing of caregivers. Caregivers' perceived control might be a target for future interventions.

Burden on Caregivers of Adults with Multiple Chronic Conditions: Intersectionality of Age, Gender, Education level, Employment Status, and Impact on Social Life

Intersectionality analysis is the study of overlapping or intersecting social identities. Intersecting social identities may have an impact on the perception of burden by family caregivers of older persons with multiple chronic conditions (MCC). The purpose of this study was to explore the interaction of social factors on the burden of caring for older adults with MCC. A total of 194 caregivers of older adults with MCC were recruited from Alberta and Ontario. Survey data were collected at two time points, six months apart. Additive and multiplicative models were analysed using a generalised linear model to determine the level of caregiver burden. Medium-high social interference (impact on social life) was associated with higher burden when adjusted for age, gender, education, and employment status. The overall results of the five-way interaction suggest that males in general had lower burden scores than females. Irrespective of their education and employment status, females had generally higher burden scores. These results add to the current body of literature, suggesting areas for further research to fill knowledge gaps, and promoting ideas for evidence-guided public health interventions that focus on caregivers.

The Impact of Cognitive and Behavioral Symptoms on ALS Patients and Their Caregivers

Previously thought to be a pure motor disease, amyotrophic lateral sclerosis (ALS) is now established as multisystem neurodegenerative disorder that lies on a continuum with frontotemporal dementia (FTD). Cognitive and behavioral symptoms primarily extend to executive function, personality, social conduct, and emotion processing. The assessment and management of cognitive and behavioral symptoms is complicated as they must be differentiated from psychological responses to a terminal diagnosis and progressive physical impairment. This is made more difficult by the limited number of studies investigating how these symptoms specifically affect patients and caregivers well-being. The current review focuses on the impact of cognitive and behavioral symptoms on patient and caregiver well-being and their implications for future research and interventions in ALS. This is an important area of research that could form the basis for more tailored, and potentially more successful, non-pharmacological interventions to improve psychological well-being among patients with ALS and their caregivers.

[Factors Influencing Psychosocial Well-Being in Family Caregivers of People with Amyotrophic Lateral Sclerosis]

PURPOSE

The purpose of this study was to identify factors influencing psychosocial well-being in family caregivers of patients with amyotrophic lateral sclerosis (ALS).

METHODS

A descriptive correlational design was used. The transactional model of stress and coping was used to investigate the psychosocial well-being of 137 family caregivers of patients with ALS. Data were collected through self-reported questionnaires from January to November 2016. Data were analyzed using an independent t-test, one-way ANOVA, Pearson's correlation, and hierarchical multiple regression analysis with the SPSS WIN 21.0 program.

RESULTS

The regression model had an adjusted R² of .49, which indicated that meaning-focused coping, social support, ALS patient-family caregiver relationship (especially a spousal relationship), and tracheostomy were significant predictors of caregivers' psychosocial well-being.

CONCLUSION

Meaning-focused coping and social support significantly influenced caregivers' psychosocial well-being. Therefore, interventions to improve caregivers' psychosocial well-being must focus on increasing meaning-focused coping and social support resources.

Family Members of Cancer Patients in Korea Are at an Increased Risk of Medically Diagnosed Depression

Objectives

Family members are often cancer patients’ primary source of social and emotional support and make a major contribution to how well patients manage their illness. We compared the prevalence of depression in the family members of cancer patients and the general population.

Methods

This study used the data from the fourth, fifth, and sixth rounds of the Korea National Health and Nutrition Examination Survey. The variable of interest was the presence of a cohabitating cancer patient in the family and the dependent variable was the presence of diagnosed depression.

Results

The odds of having medically diagnosed depression in those with a cohabitating cancer patient in the family were significantly higher than among those who did not have cancer patients in their families (odds ratio [OR], 1.56; 95% confidence interval [CI], 1.12 to 2.17; p=0.009). The OR for females was 1.59, and this increase was statistically significant (95% CI, 1.09 to 2.31; p=0.02).

Conclusions

We need to invest more effort into diagnosing and managing depression in the family members of cancer patients. This will have an impact both on their quality of life and on the well-being of patients, as supporters and caregivers play an instrumental role in helping patients manage their illness.

Caregiver experience, health-related quality of life and life satisfaction among informal caregivers to patients with amyotrophic lateral sclerosis: A cross-sectional study

AIMS AND OBJECTIVES

This study set out to describe caregiver experience, health-related quality of life and life satisfaction among informal caregivers to patients with amyotrophic lateral sclerosis and to explore factors associated with caregivers' health-related quality of life and life satisfaction.

BACKGROUND

Knowledge about factors related to caregivers' health-related quality of life and life satisfaction is important for identification of those at risk for ill health and for development of support and care.

DESIGN

A cross-sectional study.

METHODS

Forty-nine informal caregivers and 49 patients were included. Standardised and study-specific questionnaires were used for data collection on caregiver experience (Caregiver Reaction Assessment), health-related quality of life (EuroQol Visual Analogue Scale, SF-36), life satisfaction (Life Satisfaction Checklist) and caregiver- and patient-related factors. Associations were explored by regression analyses.

RESULTS

Both positive and negative caregiver experience were reported, and health-related quality of life and life satisfaction were below national reference values. Positive experience was associated with better and negative with worse mental health-related quality of life. Factors related to informal caregivers (sex, age, living conditions) and patients (anxiety and/or depression) were related to caregivers' health-related quality and life satisfaction.

CONCLUSION

The results indicate the need to consider the individual caregiver's experience when planning services, care and support. It is important to adopt person-centred care, not only for patients but also for their informal caregivers, as factors related to both parties were associated with the informal caregivers' health-related quality of life and life satisfaction.

RELEVANCE TO CLINICAL PRACTICE

Our study suggests that promoting positive experience and providing services and support to reduce negative aspects of caregiving might be important strategies for healthcare personnel to improve informal caregivers' health.

Mutual support groups for family caregivers of people with amyotrophic lateral sclerosis in Italy: A pilot study

Family caregivers of people with amyotrophic lateral sclerosis (ALS) live stressful lives in which they spend most of their time caring for their loved ones and managing difficult situations, thereby reducing the time spent in taking care of themselves. This situation may last several years. Previous literature has widely highlighted that this situation reduces caregivers' quality of life and increases their psychological distress and risk of health problems, but there is a lack of studies that focus on psychological interventions for these situations. This qualitative study examined a pilot experience of two mutual support groups for family caregivers of people with ALS. The aim was to identify caregivers' needs, the prominent aspects of their experience, and to understand whether and how this intervention strategy might help them. Six partners (four men and two women) and six adult children (five women and one man) participated in the groups, which were conducted in northern Italy. After the support groups finished, participants underwent semi-structured interviews. The authors conducted a content analysis of the transcripts of the interviews and the 20 group sessions. The thematic areas identified were "caregiving," "being the son/daughter of a person with ALS," "being the partner of a person with ALS," "group experience" and "group evaluation." The caregiving experience was profoundly different depending on whether the caregiver was a son/daughter or a partner of a patient with ALS. Moreover, comparison with peers and mutual support helped participants to better cope with ALS and its consequences, to improve their care for their relatives and to overcome typical caregiver isolation. These results suggest the usefulness of involving communities in caregiver support in order to create new networks and activate personal and social resources for well-being.

A comparative study to identify factors of caregiver burden between baby boomers and post baby boomers: a secondary analysis of a US online caregiver survey

Background

Baby boomers’ position in the caregiving context is shifting from caregiver to care recipient as the population ages. While the unique characteristics of baby boomer caregivers are well established in caregiving literature, there is limited information about the next caregiving group after the baby boomers. In this study, the sociodemographic and caregiving-related characteristics of the two generations are compared and specific factors contributing to caregiver burden between baby boomer and post baby boomer caregivers are identified.

Methods

This cross-sectional and correlational study used secondary analysis of data from the National Alliance for Caregiving and the American Association of Retired Persons. A structured online survey was conducted in 2014 with randomly selected samples (n = 1069) in the United States focusing on sociodemographics, caregiving-related characteristics, and burden of care. Descriptive statistics, multivariate linear regression analyses, and Steiger’s Z-test were used to identify group differences in multivariate factors related to caregiver burden in two generational groups.

Results

Baby boomers and post baby boomers experienced caregiver burden to a similar degree. Caregiving-related factors are more likely to increase burden of care than sociodemographics in both groups. Caregiving without choice and spending longer hours on caregiving tasks were common factors that increased the burden in both generational groups (all p values < 0.01). However, post baby boomer caregivers reported additional challenges, such as unemployment during caregiving, the dual responsibility of both adult and child care, and a family relationship with the care recipient.

Conclusions

Due to the aging population of baby boomers, post baby boomers encounter different challenges related to caregiving burden, which is often considered an additional workload in their life course. Current policy and program tailored to baby boomers should be re-designed to meet the different needs of emerging caregivers. Specific vulnerable subgroups should have priority to receive the benefits of specific policies, such as those without choice and younger, working caregivers.

Caregiver burden in amyotrophic lateral sclerosis: A systematic review

BACKGROUND

Informal caregivers of patients with amyotrophic lateral sclerosis experience increased levels of caregiver burden as the disease progresses. Insight in the factors related to caregiver burden is needed in order to develop supportive interventions.

AIM

To evaluate the evidence on patient and caregiver factors associated with caregiver burden in amyotrophic lateral sclerosis informal caregivers.

DESIGN

A systematic review.

DATA SOURCES

Four electronic databases were searched up to 2017. Studies that investigated quantitative relations between patient or caregiver factors and caregiver burden were included. The overall quality of evidence for factors was assessed using the Grading of Recommendations Assessment, Development and Evaluation approach.

RESULTS

A total of 25 articles were included. High quality of evidence was found for the relation between caregiver burden and the factor "behavioral impairments." Moderate quality of evidence was found for the relations between caregiver burden and the factors "feelings of depression" of the caregiver and "physical functioning" of the patient. The remaining rated caregiver factors-"feelings of anxiety," "distress," "social support," "family functioning," and "age"-and patient factors-"bulbar function," "motor function," "respiratory function," "disease duration," "disinhibition," "executive functioning," "cognitive functioning," "feelings of depression," and "age"-showed low to very low quality of evidence for their association with caregiver burden.

CONCLUSION

Higher caregiver burden is associated with greater behavioral and physical impairment of the patient and with more depressive feelings of the caregiver. This knowledge enables the identification of caregivers at risk for caregiver burden and guides the development of interventions to diminish caregiver burden.

Neurodegenerative and psychiatric diseases among families with amyotrophic lateral sclerosis

OBJECTIVE

To estimate risks of neurodegenerative and psychiatric diseases among patients with amyotrophic lateral sclerosis (ALS) and their families.

METHODS

We conducted a register-based nested case-control study during 1990-2013 in Sweden to assess whether patients with ALS had higher risks of other neurodegenerative and psychiatric diseases before diagnosis. We included 3,648 patients with ALS and 36,480 age-, sex-, and county of birth-matched population controls. We further conducted a follow-up study of the cases and controls to assess the risks of other neurodegenerative and psychiatric diseases after ALS diagnosis. To assess the potential contribution of familial factors, we conducted similar studies for the relatives of patients with ALS and their controls.

RESULTS

Individuals with previous neurodegenerative or psychiatric diseases had a 49% increased risk of ALS (odds ratio 1.49, 95% confidence interval 1.35-1.66) compared to individuals without these diseases. After diagnosis, patients with ALS had increased risks of other neurodegenerative or psychiatric diseases (hazard ratio 2.90, 95% confidence interval 2.46-3.43) compared to individuals without ALS. The strongest associations were noted for frontotemporal dementia, Parkinson disease, other dementia, Alzheimer disease, neurotic disorders, depression, stress-related disorders, and drug abuse/dependence. First-degree relatives of patients with ALS had higher risk of neurodegenerative diseases, whereas only children of patients with ALS had higher risk of psychiatric disorders, compared to relatives of the controls.

CONCLUSIONS

Familial aggregation of ALS and other neurodegenerative diseases implies a shared etiopathogenesis among all neurodegenerative diseases. The increased risk of psychiatric disorders among patients with ALS and their children might be attributable to nonmotor symptoms of ALS and severe stress response toward the diagnosis.

A study of burden of care and its correlates among family members supporting relatives and loved ones with traumatic spinal cord injuries

Objective:

To understand and describe in a sample of caregivers of persons with spinal cord injury, their burden of care, resilience and life satisfaction and to explore the relationship between these variables.

Design:

Cross-sectional design.

Setting:

One Spinal Cord Injury Acute Inpatient Unit from a general hospital.

Subjects:

Seventy-five relatives of persons with spinal cord injuries (84% women) with a mean age of 48.55 ( SD = 12.55) years.

Interventions:

None.

Measures:

Demographics (neurological loss and severity according to the American Spinal Injury Association criteria), the Zarit Burden Interview, the Resilience Scale and the Life Satisfaction Checklist.

Results:

All caregivers experienced feelings of different intensities of burden (52% mild-to-moderate, 43% moderate-to-severe and 5% severe), and none of them expressed little or no burden at the assessment moment. Caregivers’ main worries were “dependence” and “the future of the injured.” Resilience was medium-to-high (mean = 141.93, SD = 23.44) for the whole sample with just a minority of them revealing low (15%) or very low resilience (7%). The highest scores were obtained in relation to “caregivers’ independence” and “meaning of their lives.” Life satisfaction scores were medium-to-high (mean = 36.6, SD = 6). These scores were not related to demographics or the severity of the injury. Zarit Burden Interview scores were negatively correlated to Resilience Scale ( r = −.370, P = .001) and Life Satisfaction Checklist scores ( r = −.412, P < .001).

Conclusion:

More resilient and satisfied caregivers experienced lower burden. Burden is moderate-to-high and mainly related to uncertainty about the future, caregivers’ insecurity with caregiving and dependence of the injured.
