Care burden and depression in caregivers caring for patients with intractable neurological diseases at home in Japan

Neurological update: the palliative care landscape for atypical parkinsonian syndromes

Atypical parkinsonian syndromes are neurodegenerative conditions, characterised by rapid disease progression and shorter life expectancy compared to idiopathic Parkinson's disease. These conditions inflict substantial physical and psychosocial burden on patients and their families; hence, there is a clear rationale for a palliative care approach from diagnosis. An interdisciplinary care model has been shown to improve symptom burden, quality of life and engagement with advance care planning, in a heterogeneous group of neurodegenerative conditions. In this update, we summarise how the landscape for treating these patients has changed and the questions that still need to be resolved.

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.

Outpatient neuropalliative care

Palliative care is an approach to patient care that focuses on enhancing quality of life through relief of physical, emotional, and spiritual sources of distress and patient-tailored discussions about goals of care. The palliative care approach can be delivered by any provider, and can occur alongside disease-modifying therapies. For patients with a serious neurologic illness or a neurodegenerative disease, neuropalliative care is a growing field focused on providing high-quality palliative care to neurology patients. There are three models of neuropalliative care delivery in the outpatient setting: a consultative model with a palliative care specialist, an integrated model with an embedded palliative care provider, and a primary palliative care model with the patient's neurology provider. The main components of an outpatient palliative care visit include symptom assessment and treatment, communication about serious illness, advance care planning, and assessment of caregiver needs. For patients with advanced illness, palliative care can help facilitate timely referral to hospice. Through a palliative care approach, outpatient care for patients with serious neurologic disease or neurodegenerative disease can focus on the issues most important to the patient, promote improved illness understanding and planning, and can improve the overall quality of care.

Care partner support

Palliative care focuses on improving the quality of life of people living with serious illness and their family carers. However despite policy, clinical, and research evidence underpinning the importance of a family approach to care, as well as justification for early palliative care integration, systemic inadequacies have impeded the quality of family support. This chapter provides an overview of common concepts in caregiving, a framework through which carer well-being can be understood, and an overview of disease specific considerations for care partners. There are several main needs that are relevant to care partners across disease settings include (1) information and guidance to prepare them for the role; (2) how to alleviate discomfort for the person with illness; (3) enhancing skills for the physical tasks of the role; (4) strategies for managing the psychological, and financial implications of the care partner role; and (5) assistance in advance care planning and on preparing for the care recipient's death. Care partner coping is a result of complex interactions between stressors and mediators as they navigate chronic illness, but palliative providers with an understanding of these factors are well-positioned to address carer risk factors and provide appropriate support.

Investigating the burden of disease dimensions (time-dependent, developmental, physical, social and emotional) among family caregivers with COVID-19 patients in Iran

Background

The caregivers of patients with covid-19 face constant responsibilities such as providing personal, health, and social care to family, which can be physically, and emotionally exhausting resulting in a considerable stress burden. Therefore, given the importance of the subject, this study aimed to investigate the burden of disease dimensions (time-dependent, developmental, physical, social and emotional) among family caregivers with covid-19 patients in Iran.

Methods

This cross-sectional study was conducted one year after the onset of the Covid-19 outbreak in Iran. Family caregivers of Covid-19 patients discharged from the hospitals in Kerman city, Iran, were chosen by simple randomization (n = 1500). Data were collected utilizing a demographic characteristics inventory created by the researcher as well as the Novak and Guest Caregiver Burden Inventory. Descriptive statistics such as mean and standard deviations, frequency, and percentages and analytical statistics such as Kolmogorov–Smirnov, T-test, ANOVA, and Multivariate Linear Regression were used for data analysis using the 20, SPSS Inc., Chicago, IL Software at the level of P < 0.05.

Results

The results demonstrated that the mean score of family caregiver burden was 2.61±0.6 and the severity of this burden was in a moderate range. The finding showed a statistical difference was seen between the family caregiver burden mean score of participants in terms of gender, duration of treatment, age and employed status. The multivariable linear regression model showed demographic variables of caregivers included (female, married, employed, elderly, low income and poor education) had a beneficial influence on family caregiver burden.

Conclusion

The findings of this study can increase the awareness of health managers, about the level of burden of disease among family caregivers from the covid-19 patients and can help to provide economic, social and psychological support programs for improvement and reducing the burden of disease of caregivers during the covid-19 outbreaks.

COVID-19 pandemic and the international classification of functioning in multiple system atrophy: a cross-sectional, nationwide survey in Japan

The present study aimed to determine the magnitude of and risk factors for the effects of the COVID-19 pandemic on the international classification of functioning, disability and health (ICF) in patients with multiple system atrophy (PwMSA). The study was part of a cross-sectional, nationwide, multipurpose mail survey for Japanese PwMSA from October to December, 2020. The primary outcome was the impact of the early COVID-19 pandemic on ICF functioning, consisting of body function, activity, and participation. Age, sex, disease type, disease duration, and dwelling place were asked as participants’ characteristics, and the multiple system impairment questionnaire (MSIQ), patient health questionnaire-2, modified rankin scale, barthel index, life-space assessment (LSA), and EuroQoL were examined. Multivariate logistic regression analyses were performed to identify independent risk factors for a worse function score due to the COVID-19 pandemic for each ICF functioning domain. A total of 155 patients (mean age 65.6 [SD 8.1] years; 43.9% women; mean disease duration 8.0 [SD 6.2] years; 65% MSA with cerebellar ataxia, 13% MSA with parkinsonism, 9% MSA with predominant autonomic features) were analyzed. Of the ICF functioning domains, the respondents reported that the early COVID-19 pandemic affected body function in 17.4%, activity in 17.6%, and participation in 46.0%. The adjusted multivariate model identified MSIQ and LSA as the two variables that independently contributed to all domains. The COVID-19 pandemic affected ICF functioning of PwMSA in Japan, and the severity of disease-related impairments and a large daily living space were common risk factors. These results help support the focus on patient characteristics for medical and social welfare support.

Caregiver Burden in Late-Stage Parkinsonism and Its Associations

BACKGROUND

Patients in the late stages of parkinsonism are highly dependent on others in their self-care and activities of daily living. However, few studies have assessed the physical, psychological and social consequences of caring for a person with late-stage parkinsonism.

PATIENTS AND METHODS

Five hundred and six patients and their caregivers from the Care of Late Stage Parkinsonism (CLaSP) study were included. Patients' motor and non-motor symptoms were assessed using the UPDRS and Non-motor symptom scale (NMSS), Neuropsychiatric inventory (NPI-12), and caregivers' health status using the EQ-5D-3 L. Caregiver burden was assessed by the Zarit Burden Interview (ZBI).

RESULTS

The majority of caregivers were the spouse or life partner (71.2%), and were living with the patient at home (67%). Approximately half of caregivers reported anxiety/depression and pain/discomfort (45% and 59% respectively). The factors most strongly associated with caregiver burden were patients' neuropsychiatric features on the total NPI score (r = 0.38, p < 0.0001), total NMSS score (r = 0.28, p < 0.0001), caring for male patients and patients living at home. Being the spouse, the hours per day assisting and supervising the patient as well as caregivers' EQ-5D mood and pain scores were also associated with higher ZBI scores (all p < 0.001).

CONCLUSION

The care of patients with late stage parkinsonism is associated with significant caregiver burden, particularly when patients manifest many neuropsychiatric and non-motor features and when caring for a male patient at home.

The Full Mediating Role of Loneliness on the Relationship Between Social Support and Depression Among Rural Family Caregivers of Persons With Severe Mental Illness

Objective: Depression is a common and overwhelming psychiatric disorder among family caregivers of persons with severe mental illness (SMI). The interrelationships among social support, loneliness, and depression, especially among this relatively vulnerable group, are poorly understood. The aim of the present study was to test the hypothesis that the social support contributes to the alleviation of depression, through its effect on reducing loneliness.

Methods: A survey of 256 rural family caregivers of persons with SMI was conducted between December 2017 and May 2018 in Chengdu City, Sichuan Province, China. Social support, loneliness and depression were measured. A series of multiple linear regression models and bootstrapping procedure were performed to examine the mediating effects of loneliness on the association between social support as well as its components and depression.

Results: The proportion of family caregivers of persons with SMI who reported significant depressive symptoms was 53.5%. Loneliness fully mediated the negative association between social support and depression. As to three components of social support, subjective support and objective support only had indirect associations with depression mediated by loneliness, while support utilization had both direct and indirect relationships with depression.

Conclusion: The current study highlighted that social support and its three components may acted as protective factors by decreasing the feelings of loneliness, which created a beneficial effect on depression among family caregivers of persons with SMI.

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.

Rehabilitation medicine in palliative care of chronic neurological conditions

Background

People living with long-term neurological conditions (LTNC) often require palliative care. Rehabilitation medicine specialists often coordinate the long-term care of these patients.

Objective

The aim of the present review was to undertake systematic literature searches to identify the evidence on palliative care for people with LTNC to guide rehabilitation medicine specialists caring for these patients in the UK.

Methods

We searched for evidence for (1) discussion of end of life, (2) planning for end-of-life care, (3) brief specialist palliative care interventions, (4) support for family and carers, (5) training of rehabilitation medicine specialists in palliative care, and (6) commissioning of services. The databases searched were MEDLINE, EMBASE, CINAHL, PsycINFO, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, Database of Abstracts of Reviews of Effects, NHS Economic Evaluation Database and Health Technology Assessment Database. Evidence was assimilated using a simplified version of the Grading of Recommendations Assessment, Development and Evaluation method.

Results

We identified 2961 records through database searching for neurological conditions and 1261 additional records through database searches for specific symptoms. We removed duplicate records and conference presentations. We screened 3234 titles and identified 330 potentially relevant abstracts. After reading the abstracts we selected 34 studies for inclusion in the evidence synthesis.

Conclusions

From the evidence reviewed we would like to recommend that we move forward by establishing a closer working relationship with specialists in palliative care and rehabilitation medicine and explore the implications for cross-specialty training.

Determinants of caregiver burden of persons with disabilities in a rural district in Egypt

BACKGROUND

Family caregivers are critical partners in the plan of care of people with disabilities. The study aims to demonstrate the factor structure and internal consistency of the Caregiver Burden Inventory (CBI) among the studied caregivers of disabled persons and to determine the effects of patients' and caregivers' characteristics on the burden and its dimensions.

METHODS

A cross-sectional study among 260 family caregivers of disabled patients was carried out in a randomly chosen rural area, Minia, Egypt, 2019. Exploratory factor analysis (EFA) was conducted to determine the factorial validity of the CBI. Multiple linear regression was used to identify the significant factors affecting the burden.

RESULTS

Factor analysis resulted in a five-factor solution using 20 items (four for each dimension) accounting for 72.7% of the total variance. The CBI and its dimensions showed high internal consistency (Cronbach's alpha value > 0.70). Education of caregiver, family income, mental impairments, and mixed disabilities were significant predictors of total CBI burden.

CONCLUSIONS

CBI is an effective multidimensional measure of the caregiver burden of disabled subjects. Caregivers experienced a distinct level of burden that is determined by caregiver and care recipient characteristics. Therefore, support and individualized counseling services should be optimized.

Belastungen in der Betreuung von Parkinson-Patientinnen und - Patienten

Patientinnen und Patienten (Pat.) mit Parkinson-Krankheit bedürfen mit zunehmender Krankheitsdauer und Schweregrad persönlicher Betreuung, die meist von weiblichen Angehörigen gewährleistet wird. Die Belastungen für pflegende Angehörige resultieren einerseits aus den motorischen Beeinträchtigungen der Pat., andererseits von neurokognitiven und neuropsychiatrischen Symptomen sowie Verhaltensstörungen, Störungen des autonomen Nervensystems, der Miktion, des Schlafes und der Selbstständigkeit. Gesundheitliche Probleme der Betreuungsperson, u. a. Depression und Angst, emotionale Probleme mit dem Pflegling, Beeinträchtigung des Schlafs, sowie Einschränkungen in persönlichen Anliegen, Beruf, Familie, Freizeitgestaltung, sozialen Aktivitäten, finanzielle Einbußen und mangelhafte soziale Unterstützung stellen weitere Belastungsfaktoren dar. Personen mit dem Risiko einer erheblichen Betreuungsbelastung sind frühzeitig zu identifizieren, um ihnen Informationen über die Krankheit und Unterstützungsmöglichkeiten sowie entsprechende personelle, psychologische und finanzielle Unterstützung zukommen zu lassen.

Health Professionals' Experience of Barriers in Empowering People with Spinal Cord Injury: a Qualitative Inquiry

Introduction: Empowering an individual with spinal cord injury as far as possible is an experience with various social and cultural aspects. This study investigated health professionals' experiences of barriers in empowering individuals with spinal cord injuries.

Methods: This was a qualitative inquiry with a conventional content analysis approach. A number of 11 healthcare professionals who were members of Iran Spinal Cord Injuries Research National Network or had been working in a related research center for at least three years participated in the study. A purposive sampling method was applied until reaching data saturation. The data were collected by semi-structured interviews. The collected data were managed with MAXQDA software version 13.

Results: Three main themes as barriers in empowering people with spinal cord injury emerged: 1) Lack of patient-and-family-centered education, 2) Failure in providing sufficient healthcare services and 3) Inappropriate setting for using rehabilitation services.

Conclusion: These finding can help policymakers to provide better social facilities and more support services for people with spinal cord injuries and their families. Further research is needed to investigate barriers to empowerment from the perspective of individuals with SCI and their families.

Caregiver Burden in Primary Congenital Glaucoma

PURPOSE

To evaluate the demographic, clinical, and socioeconomic factors associated with variation in the quality of life (QOL) in caregivers of children with primary congenital glaucoma (PCG) in south India.

DESIGN

Cross-sectional survey.

METHODS

Caregivers of children younger than 18 with diagnosed PCG were prospectively enrolled at Aravind Eye Hospital in Madurai and Coimbatore, India. Participants completed 2 questionnaires, the PHQ-9 (9-item Patient Health Questionnaire) and the CarCGQoL (Caregivers Congenital Glaucoma QOL Questionnaire). Clinical, demographic, and socioeconomic data were obtained for each child-caregiver dyad. Rasch-calibrated scores were calculated for patient-reported outcome measures. Spearman correlation and linear regression were used to analyze data to determine associations with caregiver QOL.

RESULTS

There were 70 caregivers (mean age 32.1, 77.1% female) of 70 children with PCG (mean age 7.7, 37.1% female) included in the study. In univariate and multivariable analyses, child's age (β = -0.04; 95% confidence interval, -0.08 to -0.01) and duration of disease (β = - 0.03; 95% confidence interval, -0.07 to -0.01) were the only factors associated with CarCGQoL. Survey items related to anger, self-confidence, irritability, appetite, and interest in leisure activities had the lowest scores. There was a negative correlation between CarCGQoL and PHQ-9 scores (r = -0.66, P < .01), indicating that worse caregiver QOL was significantly correlated with more depressive symptoms.

CONCLUSION

This study identified traits associated with QOL decline, as well as the QOL issues most likely to affect caregivers of children with PCG in south India. Findings from this study may be important for designing interventions to improve caregivers' QOL, thereby maximizing their ability to care for children with PCG.

Analysis of caregiver burden in palliative care: An integrated review

The inclusion of caregivers in a holistic care approach represents a basic principle in palliative care. However, many palliative care professionals have a lack of understanding of difficulties or unmet needs among caregivers. To enhance the quality of life of caregivers and the quality of care for patients, healthcare professionals should be better informed about the constructs of caregiver burden. The aim of this study is to synthesize the concept of caregiver burden in palliative care, providing implications for the caregivers and their support systems. This concept analysis study adopts the integrative review approach and the basic text analysis method (ie, word frequency). The PubMed, CINAHL, Embase, and PsycINFO databases are explored for eligible studies. From this literature search, 66 articles from 1998 to 2018 are located. After data collection is completed, the two authors independently evaluate the quality of studies published before 1 September 2018. The caregiver burden is then redefined with its attributes, antecedents, consequences, empirical referents, and facilitators. It is recommended that the multidimensional concept of caregiver burden in palliative care be measured by considering caregiver characteristics and the caregiving context.

The unmet needs of family members of patients with progressive neurological disease in the Czech Republic

BACKGROUND

Caring for patients with a progressive neurological disease (PND) causes stress that may impact on the state of health as well as the quality of life of the caring family.

OBJECTIVE

The aim of the study was to explore the unmet needs of the family members of patients with PND in advanced stages.

METHODS

Grounded theory (constructivist approach) was used to conceptualize the patterns of unmet care needs. Data collection methodology involved focus groups (n = 4) and interviews, in which a total of 52 people participated (patients, family members, and professionals).

RESULTS

Based on the data analysis, three domains (family situation, role of the caregiver, and professional help) were identified, which illustrate the unmet needs. In particular, lack of information about the disease and available support available resulted in a deterioration mutual understanding between the patient, family, and the medical staff; also increased stress for the caregiver, and lowered quality of life for the caring family.

CONCLUSION

Family members expect health workers to provide them with support, which includes informing them about the possible help available from the health and social welfare systems.

The Comprehensive Management of Cerebellar Ataxia in Adults

PURPOSE OF REVIEW

In this review, we present the multidisciplinary approach to the management of the many neurological, medical, social, and emotional issues facing patients with cerebellar ataxia.

RECENT FINDINGS

Our holistic approach to treatment, developed over the past 25 years in the Massachusetts General Hospital Ataxia Unit, is centered on the compassionate care of the patient and their family, empowering them through engagement, and including the families as partners in the healing process. We present the management of ataxia in adults, beginning with establishing an accurate diagnosis, followed by treatment of the multiple symptoms seen in cerebellar disorders, with a view to maximizing quality of life and effectively living with the consequences of ataxia. We discuss the importance of a multidisciplinary approach to the management of ataxia, including medical and non-medical management and the evidence base that supports these interventions. We address the pharmacological treatment of ataxia, tremor, and other associated movement disorders; ophthalmological symptoms; bowel, bladder, and sexual symptoms; orthostatic hypotension; psychiatric and cognitive symptoms; neuromodulation, including deep brain stimulation; rehabilitation including physical therapy, occupational therapy and speech and language pathology and, as necessary, involving urology, psychiatry, and pain medicine. We discuss the role of palliative care in late-stage disease. The management of adults with ataxia is complex and a team-based approach is essential.

Neuropalliative Care: A Practical Guide for the Neurologist

Neuropalliative care is a new and growing field within neurology that focuses on improving the quality of life of patients with serious neurologic illnesses. While specialty-level palliative care training is available to interested neurologists, all neurologists can strive to provide primary palliative care for their patients. In this review, we will describe the scope of neuropalliative care, define patient populations who may benefit from palliative care, and explore the communication and symptom management skills essential to palliative care delivery.

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.

Factors to consider for motor neurone disease carer intervention research: A narrative literature review

OBJECTIVE

The experience of caregiving in the context of motor neurone disease (MND) is extremely challenging. Over the past 15 years, quantitative and qualitative studies have delineated the psychosocial aspects of this experience, exploring its impact on caregivers' quality of life, rates of depression, distress, anxiety, and burden. Our paper aimed to provide an overview of the lived experience of MND caregivers, identifying the variables that can influence MND caregiver functioning that are relevant to the development of an intervention.

METHOD

A narrative review was conducted, synthesizing the findings of literature retrieved from 2000 to early 2016.

RESULTS

A total of 37 articles were included in the review. The articles varied considerably in terms of methodology and quality. The main influential aspects reported and identified were factors pertaining to the patient, factors intrinsic to the caregiver, relationship factors, and social support factors.

SIGNIFICANCE OF RESULTS

There is evidence to support the fact that caregivers have poorer outcomes when they care for patients with a more severe clinical profile, poorer emotional health or neurobehavioral concerns, or when the caregivers themselves struggle with adaptive problem-solving and coping skills. The availability and use of social support are also likely to be important for caregiver psychosocial outcomes. Further investigation is required to clarify the influence of changes in the relationship with the patient. Significant factors affecting the caregiver experience are considered in relation to their amenability to psychosocial intervention. Recommendations are made regarding the optimal features of future psychosocial intervention research.

[Depression and caregiving burden in families of patients with amyotrophic lateral sclerosis]

PURPOSE

The purpose of this study was to describe depression, caregiving burden and the correlation of the two variables in the families of patients with amyotrophic lateral sclerosis (ALS) and to clarify factors predicting caregiving burden.

METHODS

A descriptive and cross-sectional study was conducted with 139 family members who provided care to patients with ALS. The characteristics of patients and families, Korean-Beck Depression Inventory (K-BDI), Korean version of Zarit Burden Interview (K-ZBI) and Korean-Amyotrophic Lateral Sclerosis Functional Rating Scale - Revised (K-ALSFRS-R) were used as study measures.

RESULTS

The mean score for K-BDI was 19.39 out of 63 suggesting sub-clinical depression and 38.2% of the family members exhibited depression. The mean score for K-ZBI was 66.03 out of 88. The predictors for K-ZBI were K-BDI, age of family member, length of time spent per day in caring, relationship to patient and K-ALSFRS-R.

CONCLUSION

The results of this study suggest that levels of depression and caregiving burden are high among family members caring for patients with ALS. As depression is associated with caregiving burden, screening and emotional supports should be provided to reduce the burden of care for these family. Support programs to alleviate the care burden are also needed, considering family demographics, time per day in caring giving and K-ALSFRS-R.

Influence of family dynamics on burden among family caregivers in aging Japan

BACKGROUND

Long-term care for the elderly is largely shouldered by their family, representing a serious burden in a hyper-aging society. However, although family dynamics are known to play an important role in such care, the influence of caring for the elderly on burden among caregiving family members is poorly understood.

OBJECTIVE

To examine the influence of family dynamics on burden experienced by family caregivers.

METHODS

We conducted a cross-sectional study at six primary care clinics, involving 199 caregivers of adult care receivers who need long-term care. Participants were divided into three groups based on tertile of Index of Family Dynamics for Long-term Care (IF-Long score), where higher scores imply poorer relationships between care receivers and caregiving family: best, <2; intermediate, 2 to <5; worst, ≥5. The mean differences in burden index of caregivers (BIC-11) between the three groups were estimated by linear regression model with adjustment for care receiver's activity of daily living and cognitive function.

RESULTS

Mean age of caregivers was 63.2 years (with 40.7% aged ≥ 65 years). BIC-11 scores were higher in the worst IF-Long group (adjusted mean difference: 4.4, 95% confidence interval: 1.2 to 7.5) than in the best IF-Long group. We also detected a positive trend between IF-Long score and BIC-11 score (P-value for trend <0.01).

CONCLUSION

Our findings indicate that family dynamics strongly influences burden experienced by caregiving family members, regardless of the care receiver's degree of cognitive impairment. These results underscore the importance of evaluating relationships between care receivers and their caregivers when discussing a care regimen for care receivers.

Depression and burden among the caregivers of visually impaired patients: a systematic review

Caregiving has evolved as an important issue not only for those receiving care, but for those providing it as well. While caregiving allows those with disabilities to better adapt, it has been shown to take a toll on the caregiver on various levels, such as invoking depression and burden. The purpose of this study was to perform a systematic review of the literature pertaining to depression and burden among caregivers of patients with visual impairment. A comprehensive literature search using multiple databases was conducted to include all articles on burden of care or depression among the caregivers of the visually impaired. Nine studies were included in this review. There was demonstrable association of depression and burden with the caregivers of the visually impaired. Communication theory, emotional contagion, and care burden were cited as factors associated with depression in these studies. A number of other elements were also identified to play a role in depression and burden, such as providing greater hours of supervision to the patient, multiple chronic conditions in the patient or caregiver, patient not completing vision rehabilitation, and female gender of the caregiver. By identifying those at risk for decreased quality of life outcomes, health care providers may be able to alter the management of the visually impaired, such as advocating the use of vision rehabilitation clinics in order to minimize the caregiver burden and depression.

An exploration of caregiver burden for children with nodding syndrome (lucluc) in Northern Uganda

BACKGROUND

Caregivers of patients with chronic illnesses are often uncompensated for work that is physically demanding, time consuming and emotionally and economically draining. This is particularly true for caregivers of children with nodding syndrome, an emergent neurological disorder of unknown etiology in resource poor settings in Africa. We aimed to explore perceptions of caregivers regarding challenges that a typical caregiver faces when caring for a child with nodding syndrome.

METHODS

We used a qualitative exploratory study design with focus group discussions and in-depth interviews to collect data. We analyzed data using the qualitative analysis software package of NVivo and thematic query building.

RESULTS

Emergent themes centered on burden of care with emotional agony as the most prominent. Subthemes reflecting the burden of care giving included child and caregiver safety concerns, burnout, social isolation and rejection, and homicidal ideation. Caregivers also complained of physical and financial constraints associated with the care of children with nodding syndrome.

CONCLUSIONS

The findings point to a high burden of care for caregivers of children with nodding syndrome and suggests the need to incorporate community-based psychosocial and mental health care services for the caregivers of affected children into the national health system response.

Burden and Depression in Caregivers of Blind Patients in New York State

PURPOSE

To describe the degree of burden of care and the proportion at risk of depression among individuals caring for legally blind patients.

METHODS

We performed a cross-sectional study of 486 individuals providing care to their family members who were legally blind. Best-corrected visual acuity of the better-seeing eye in patients determined group placement: Group 1, 20/200-10/200; group 2, 10/200 to light perception (LP); group 3, no light perception (NLP); group VF, visual field loss to <20 central degrees. Burden was evaluated using the Burden Index of Caregivers (BIC-11) and the prevalence at risk of depression was determined by the Center for Epidemiologic Studies Depression (CES-D) scale.

RESULTS

Total mean BIC-11 scores ranged from 8.78 ± 4.82 (group 1) to 12.03 ± 5.22 (group 3; p = 0.04). Daily hours spent on close supervision, intensity of caregiving and presence of multiple chronic illnesses in caregivers were the significant covariates affecting BIC-11 scores (p < 0.05). The prevalence of caregivers at risk of depression increased with vision loss from 6.9% (group 1) to 17.9% (group 3; p < 0.05). Female caregivers had an odds ratio (OR) of 2.89 for depression (95% confidence interval, CI, 1.07-3.97; p = 0.04). Caregivers with ≥2 comorbidities had OR 4.24 (95% CI 2.41-6.11) for risk of depression (p < 0.01).

CONCLUSION

Burden of care was highest among caregivers who provided greater hours of supervision. Patients with more limitations in their activities of daily living had caregivers who reported higher burden. Female caregivers and caregivers with multiple chronic illnesses were at higher risk of depression.

Burden and Depression among Caregivers of Visually Impaired Patients in a Canadian Population

Purpose/Background. This study reports the degree of burden and the proportion at risk for depression among individuals who provide care to visually impaired patients. Study Design. This is clinic-based, cross-sectional survey in a tertiary care hospital. Methods. Caregivers were considered unpaid family members for patients whose sole impairment was visual. Patients were stratified by vision in their better seeing eye into two groups: Group 1 had visual acuity between 6/18 and 6/60 and Group 2 were those who had 6/60 or worse. Burden was evaluated by the Burden Index of Caregivers and the prevalence of being at risk for depression was determined by the Center for Epidemiologic Studies Depression scale. Results. 236 caregivers of 236 patients were included. Total mean BIC scores were higher in Group 2. Female caregivers, caregivers providing greater hours of care, and caregivers of patients who have not completed vision rehabilitation programs are at higher risk for depression.

A consensus review on the development of palliative care for patients with chronic and progressive neurological disease

BACKGROUND AND PURPOSE

The European Association of Palliative Care Taskforce, in collaboration with the Scientific Panel on Palliative Care in Neurology of the European Federation of Neurological Societies (now the European Academy of Neurology), aimed to undertake a review of the literature to establish an evidence-based consensus for palliative and end of life care for patients with progressive neurological disease, and their families.

METHODS

A search of the literature yielded 942 articles on this area. These were reviewed by two investigators to determine the main areas and the subsections. A draft list of papers supporting the evidence for each area was circulated to the other authors in an iterative process leading to the agreed recommendations.

RESULTS

Overall there is limited evidence to support the recommendations but there is increasing evidence that palliative care and a multidisciplinary approach to care do lead to improved symptoms (Level B) and quality of life of patients and their families (Level C). The main areas in which consensus was found and recommendations could be made are in the early integration of palliative care (Level C), involvement of the wider multidisciplinary team (Level B), communication with patients and families including advance care planning (Level C), symptom management (Level B), end of life care (Level C), carer support and training (Level C), and education for all professionals involved in the care of these patients and families (Good Practice Point).

CONCLUSIONS

The care of patients with progressive neurological disease and their families continues to improve and develop. There is a pressing need for increased collaboration between neurology and palliative care.

DEPRESSÃO E INSUFICIÊNCIA RENAL CRÔNICA: UMA ANÁLISE PSICOSSOCIOLÓGICA

Este estudo objetivou apreender as representações sociais (RS) elaboradas por pacientes nefrológicos em tratamento da hemodiálise e por seus familiares acerca da depressão e da insuficiência renal crônica (IRC). A amostra foi não probabilística, com 52 participantes, dos quais 26 eram pacientes, submetidos a um questionário sociodemográfico, à Escala Hospitalar de Ansiedade e Depressão, (subescala de depressão) e a uma entrevista semiestruturada. Os dados foram coletados em três hospitais e processados pelo SPSS 19.0 e pelo Alceste, sendo analisados por meio da estatística descritiva e análise lexical. Verificou-se que a RS da depressão foi ancorada nos elementos psico/cognitivo, físico/orgânico e psicossocial, objetivada principalmente na tristeza e no isolamento. A IRC foi representada com base nas adversidades psicossociais vivenciadas pelos grupos de pertença investigados. Observou-se que esta doença foi ancorada no suporte familiar e espiritual, nas restrições hídricas e alimentares, sendo associada ao desconhecimento da hemodiálise.

Depression and anxiety in amyotrophic lateral sclerosis: correlations between the distress of patients and caregivers

INTRODUCTION

Depression and anxiety are common in amyotrophic lateral sclerosis (ALS) patients and caregivers.

METHODS

In this study we investigated 93 ALS patients and their 93 caregivers. Depression and anxiety were quantified by the Hamilton Depression Rating Scale and Hamilton Anxiety Rating Scale, respectively.

RESULTS

Very strong correlations between depression and anxiety were found among patients and their caregivers. The severity of depression and anxiety of patients correlated moderately with that of their caregivers. No correlations were found between the severity of depression and anxiety and ALS Functional Rating Scale-Revised (ALSFRS-R) score or for disease duration among patients and caregivers. However, severity of depression and anxiety in caregivers correlated with their age.

CONCLUSIONS

Depression and anxiety in ALS patients and their caregivers were associated closely with each other but not with physical disability or disease duration in our Chinese population.

Effect of yoga therapy on anxiety and depressive symptoms and quality-of-life among caregivers of in-patients with neurological disorders at a tertiary care center in India: A randomized controlled trial

CONTEXT

The concerns of caregivers of patients with neurological disorders have been a felt need for a long time, with many of them experiencing significant psychiatric morbidity.

AIMS

This study aimed to find the effect of yoga in reducing anxiety and depression, as well as improving quality-of-life in caregivers of patients with neurological disorders.

SETTINGS AND DESIGN

The study was conducted using a randomized controlled design, with yoga intervention and waitlisted controls.

METHODOLOGY

SIXTY CONSENTING CAREGIVERS OF INPATIENTS IN NEUROLOGY WARDS WERE RANDOMIZED INTO TWO GROUPS: Yoga and control. Demographic variables except years of education and length of caretaking were comparable in the two groups, as also baseline scores of anxiety, depression and quality-of-life. A specific yoga module comprising yogāsanas, prāṇāyāma, and chanting was taught to the participants in the yoga group by the researcher. At follow-up 43 patients (yoga n=20 and control group n=23) were available. Two-way repeated measures analysis of variance was used to test the change from pre-test to post-test scores within and between groups. Analysis of covariance was performed to compare the post-test scores between the groups adjusting for education and length of caretaking.

RESULTS

Following one month intervention of yoga therapy, there was a significant (P<0.001) decrease in anxiety and depression scores, as well as improved quality-of-life among the participants in the yoga group as compared with the control group.

CONCLUSION

This study highlights the usefulness of a yoga intervention for caregivers of inpatients with neurological problems. The small sample size and lack of blinding were some of the limitations of this study.

A 10-year literature review of family caregiving for motor neurone disease: moving from caregiver burden studies to palliative care interventions

BACKGROUND

There is growing awareness that different terminal diseases translate into different family caregiver experiences, and the palliative and supportive care needs of these families are both similar and unique. Family members caring for people with motor neurone disease may experience exceptional strain due to the usually rapid and progressive nature of this terminal illness.

AIM

The purpose of this review is to synthesize contemporary research and provide a comprehensive summary of findings relevant to motor neurone disease family caregivers, as well as highlight some of the suggested interventions to alleviate burden and improve quality of life for this group.

DESIGN

We conducted a comprehensive review of empirical research on family caregiving for people with motor neurone disease in peer-reviewed journals published in English, January 2000-April 2011. Fifty-nine studies met the inclusion criteria.

RESULTS

This comprehensive literature review was consistent with previous research documenting the substantial burden and distress experienced by motor neurone disease family caregivers and revealed important points in the trajectory of care that have the potential for negative effects. The diagnosis experience, assisted ventilation, cognitive changes and end-of-life decision making create challenges within a short time. This review has also implicated the need for improvements in access to palliative care services and highlighted the absence of interventions to improve care.

CONCLUSIONS

Caregiver burden and quality-of-life studies on motor neurone disease family caregivers have so far dominated the research landscape .The focus needs to be on developing interventions that provide direct practical and psychosocial supports for motor neurone disease family caregivers.

Comparison of caregiver strain in Parkinson's disease between Yamagata, Japan, and Maryland, The United States

BACKGROUND

Japan and the United States (US) have different cultures of caregiving including differences in family structure and social programs that may influence caregiver strain. Differences in caregiver strain between regions in Japan and in the US have not been investigated in patient-spouse dyads in PD.

OBJECTIVES

To compare caregiver strain in spouses of PD patients between Yamagata, Japan and Maryland, US. Correlations between caregiver strain and patient/spousal variables are also examined.

METHODS

In Yamagata and Maryland, spouses of patients with PD completed questionnaires assessing caregiver strain. Patients and spouses completed scales assessing mental health, and medical co-morbidity. PD severity and disability were assessed with the Unified Parkinson's Disease Rating Scale and the Schwab and England Activities of Daily Living Scale. Results in the two regions were compared with Chi-square and Student's t-tests. Relationships between caregiver strain and patient/spousal variables were analyzed with univariate correlations and multivariate regression.

RESULTS

178 Spouse-patient pairs were assessed. The level of caregiver strain in PD did not differ between Yamagata, Japan and Maryland, US despite differences in demographics and social support programs in the two regions. Yamagata spouses reported physical, time and financial constraints, while Maryland spouses reported more emotional distress. In both regions, spousal depression was a significant contributor to caregiver strain.

CONCLUSION

Different approaches to reduce caregiver strain will likely be necessary in Yamagata and Maryland since the contributing factors to caregiver strain are influenced by differences in culture and social supports in each country.

Caregiver burden in amyotrophic lateral sclerosis is more dependent on patients' behavioral changes than physical disability: a comparative study

Background

Behavioral changes in patients with amyotrophic lateral sclerosis (ALS) mirror those found in frontotemporal dementia (FTD). Considering the high rate of neuropsychiatric symptoms found in ALS patients, this paper examines whether caregiver burden is associated with behavioral changes over and above the physical disability of patients with ALS, and if the presence of caregivers’ depression, anxiety and stress also impacts on caregiver burden.

Methods

140 caregivers of patients with ALS participated in a postal survey investigating patients’ neuropsychiatric symptoms (Cambridge Behaviour Inventory Revised CBI-R), motor function (Amyotrophic Lateral Sclerosis Functional Rating Scale Revised - ALSFRS-R), caregiver burden (Zarit Burden Interview), and caregiver mood (Depression, Anxiety and Stress Scale- DASS21). Seventy four percent of them were caregivers of patients with limb onset and 25.7% were caregivers of patients with bulbar onset.

Results

Moderate to severe behavioral changes were reported in 10-40% of patients with ALS. The levels of depression, anxiety and stress in the caregivers reached 20%. Burden was high in 48% of the caregivers. The strongest predictor of high caregiver burden was ALS patients’ abnormal behavior rather than physical disability, with an odds ratio of 1.4, followed by caregivers’ stress.

Conclusions

Our study has identified that behavioral changes (e.g. disinhibition, impulsivity) and caregiver stress have greater impact on caregiver burden than level and pattern of physical disability.

Social support associated with quality of life in home care patients with intractable neurological disease in Japan

The aim of the present study was to investigate what kinds of social supports contribute to the higher quality of life (QOL) of home care patients with intractable neurological disease. We investigated the World Health Organization Quality of Life-BREF (WHOQOL-BREF) and social supports to 74 patients with intractable neurological disease in a city of the Aichi prefecture, Japan. Association between WHOQOL and social supports was examined using multiple logistic regression analyses adjusting activities of daily living (ADL). High WHOQOL scores were associated with “attending patient gatherings held by the public health center,” “having someone who will listen empathically to anxieties or troubles,” and ADL. Physical health was associated with ADL, while psychological well-being was related to “having a hobby,” “having someone who will listen,” and “having a hospital for admission in emergencies.” Patients not having someone who will listen were more likely to participate in the gatherings. The present findings suggest that having someone who will provide emotional support is important for home care patients with neurological diseases. Patient gatherings held by the public health center were expected to provide patients with emotional support.

Burden and depression in the caregivers of blind patients in India

PURPOSE

Several studies have examined the rates of depression in caregivers of patients with debilitating neurologic diseases. This study describes the degree of burden and the prevalence of depression among individuals caring for legally blind patients. To the best of our knowledge, no prior studies in the ophthalmic literature have reported this relationship.

DESIGN

Clinic-based, cross-sectional study.

PARTICIPANTS

We included 522 individuals in Rampur, India, providing care to their close family relatives who were legally blind. Visual acuities varied from 20/200 in the best eye, to no light perception (NLP) in each eye.

METHODS

Several surveys were completed by the caregivers of patients whose sole impairment was visual, allowing us to quantitatively and selectively assess burden and depression among caregivers of blind patients.

MAIN OUTCOME MEASURES

The Burden Index of Caregivers (BIC) was used to measure care burden and the Center for Epidemiologic Studies Depression scale was applied to determine depression.

RESULTS

Caregivers of patients with NLP experience higher burden than caregivers of patients with lesser degrees of blindness. Daily hours spent on close supervision and the intensity of care-giving were the definitive factors linked to high BIC scores (P<0.01). The prevalence of caregiver depression increased with degree of visual impairment from 16% in the 20/200 group to 48% in the NLP cohort (P<0.01). Independently related variables for depression in caregivers were daily hours required for close supervision of the patient, intensity of care-giving, low household income, and the caregiver being the parent of a blind adult child (P<0.01).

CONCLUSIONS

Severity of blindness in patients directly correlated with burden in caregivers. More severe forms of blindness meant patients require more help with their activities of daily living and additional hours of close supervision per day, both of which increase care burden. The same 2 factors also increase risk of caregiver depression along with low household income and the caregiver being the parent of a blind adult child. Awareness of the extent of burden and depression among caregivers of blind individuals is required by vision health personnel to identify at risk caregivers and implement effective interventions and support strategies.

Quality of life and emotional burden of primary caregivers: a case-control study of multiple sclerosis patients in Greece

PURPOSE

Our aim was to assess the perceived emotional burden and quality of life (QOL) in a sample of Greek primary caregivers of patients with multiple sclerosis (MS).

METHODS

Twenty-two male and 13 female primary caregivers (mean age 47.3 ± 12.4 years), and an equal number of patients with MS, completed the Greek validated version of the hospital anxiety and depression scale (HADS) and the Greek validated version of EuroQOL (EQ-5D). Thirty-five age-, gender-, and education-matched healthy controls were used for comparison.

RESULTS

Caregivers experienced higher degree of anxiety than depression. The mean score of the HADS-A subscale was 9.5 ± 4 (range 3-15), and the mean score of the HADS-D subscale was 7.1 ± 3.1 (range 2-14). The mean scores of caregivers on both HADS-A and HADS-D were significantly higher than the controls' (P < 0.0001). Twenty-two caregivers were diagnosed with manifesting anxiety, whereas 12 of them also presented depression. Highly educated caregivers were more prone to manifest increased levels of anxiety and depression. The increased psychological distress was further supported by the responses in the anxiety/depression dimension on the EQ-5D: 27 reported a moderate level of anxiety/depression and three indicated an extreme degree. The caregivers reported a mean EQ-VAS value of 61.9 ± 13.8 (range 40-100), with 10 caregivers rating their health status a score of 50 or lower; the controls scored significantly higher (90.3 ± 7.1; P < 0.0001).

CONCLUSION

The sample of caregivers we studied was psychologically burdened to a significant degree, a fact that obviously deteriorates their QOL. Appropriate psychopharmacological interventions are warranted to reduce caregivers' burden.

Health-related quality of life among community-dwelling patients with intractable neurological diseases and their caregivers in Japan

AIMS

The aims of this study were: (i) to clarify the general quality of life (QOL) of patients with intractable neurological disease; (ii) to clarify the general QOL of the caregivers of these patients; and (iii) to explore the association of QOL in patient-caregiver pairs.

METHODS

A cross-sectional survey was conducted between November 2003 and May 2004 among community-dwelling patients diagnosed with Parkinson's disease (PD), spinocerebellar degeneration (SCD), multiple system atrophy (MSA), and amyotrophic lateral sclerosis (ALS) and their caregivers using a mailed, self-administered questionnaire. To measure QOL, we used the Medical Outcome Study 36-Item Short Form (SF-36) for patients and the short form of the health-related QOL scale SF-36 (SF-8) for caregivers.

RESULTS

A total of 418 questionnaires were analyzed. For the patients, all of the general QOL domains of the SF-36 were significantly lower than the national standard value for all of the diagnoses. Physical function, role physical, and role emotional domains were also low. For caregivers, all of the QOL summary scores of the SF-8 for all diagnoses were significantly lower than the national standard value. Although there were several significant correlations of QOL between patients and caregivers, overall the correlations were low.

CONCLUSIONS

Support for patients with neurological diseases and their caregivers is needed in order to maintain physical and mental QOL.

Causes and place of death in Italian patients with amyotrophic lateral sclerosis

OBJECTIVES

To determine the causes and place of death in a cohort of Italian patients with amyotrophic lateral sclerosis (ALS). A better understanding of the likely causes of death in ALS might improve the palliative care at the end-of-life, whereas knowing the place of death will help to verify the need for highly specialized care services, e.g. hospice and nursing home.

PATIENTS AND METHODS

Between 2000 and 2008, 182 ALS patients (onset: spinal, 127; bulbar, 55; M/F: 1.6) were followed in a single ALS Tertiary Centre in Palermo, Sicily, Italy until death. Medical data for each individual patient were recorded in a large database throughout the disease course. Information concerning causes and place of death were obtained by consultation with relatives or the family physician.

RESULTS

Respiratory failure (terminal respiratory insufficiency, pneumonia) was the most frequent cause of death (81.3%), which included six cases (3.3%) who requested a terminal sedation. Sudden death and death during sleep accounted for by 6.0% and 6.6% of all deaths, respectively. Heart-related causes of death were relatively infrequent in our cohort, accounting for by 7.1% of all deaths (i.e. sudden death: 6.0% and myocardial infarct: 1.1%). Patients (85.2%) died at home.

CONCLUSIONS

The leading cause of death in ALS remains the respiratory failure, followed by the sudden death and death during sleep. Most patients in our cohort died at home, a choice that might be only partially driven by cultural factors. These findings might have a great impact on the development of the advanced and end-of-life palliative care and in the planning of specialized care services, as hospice and nursing home.

Occurrence risk and structure of depression in Parkinson disease with and without dementia: results from the GEPAD Study

BACKGROUND

This study examined the age- and gender-specific risk of depression in demented and non-demented participants, its symptom structure, and associated clinical factors in a nationwide random sample of n = 1449 outpatients with Parkinson disease (PD).

METHODS

Depression ratings were based on a cross-sectional clinical assessment including the clinical Montgomery-Asberg Depression Rating Scale (MADRS > or = 14). Parkinson disease severity was rated according to Hoehn and Yahr (HY) and the Unified Parkinson's Disease Rating Scale. Diagnosis of dementia was based on Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition; DSM-IV) criteria.

RESULTS

25.2% (CI: 22.8-27.5) of all patients met study criteria for depression. Additionally, 8.4% of patients did not exceed the MADRS cut-off but were currently being treated with antidepressants, possibly suggesting a corrected (upper limit) total prevalence of 33.6%. Females were more likely depressive than males (29.3% vs 22.4%). In both genders, depression risk was elevated 2- to 4-fold depending on HY stage. Overall, highest rates in non-demented patients were found in females at stages IV to V (53.7%, CI: 37.7-69.6). Demented patients were more likely to meet depression criteria than non-demented (up to 76.2%, 95% CI: 60.5-87.9). Depression symptom profiles for demented PD patients (as compared to non-demented) revealed no structural differences but consistently higher symptom scores. Neither age at onset of PD nor duration of disease were significantly linked with depression.

CONCLUSIONS

Depression rates are already substantially elevated at early PD stages, emphasizing the need for a thorough examination of mood disorders in all patients with PD. Depression is associated with PD severity and dementia but not with age, age at onset of PD, or disease duration. The differential associations with dementia and the statistical independence of dementia and depression also suggest that depression could not be regarded as a mere demoralisation syndrome.
