Caregiver strain in Parkinson's disease: National Parkinson Foundation Quality Initiative Study

Unveiling the invisible: a qualitative interview study on the impact of young onset Parkinson's disease on (ex-partners)

INTRODUCTION

Living with young onset Parkinson's disease (YOPD) not only affects the persons with YOPD, but also their families. Although caregiver burden has been researched in Parkinson's disease in general, little is known about the specific impact of having an (ex-)partner with YOPD. This exploratory study aimed to explore the impact of having an (ex-)partner with YOPD on daily life.

MATERIALS AND METHODS

We used a qualitative approach including semi-structured interviews with 16 (ex-)partners of people with YOPD. Interviews were audio-taped and transcribed verbatim. Qualitative thematic analysis was used to analyze the interview data.

RESULTS

Qualitative analysis revealed nine themes to describe the impact of having an (ex-)partner with YOPD: (1) Psychosocial impact, (2) Impact on taking care of children, (3) Impact on working life, (4) Impact on intimacy and (sexual) relationships, (5) Impact on daily life, (6) Acceptance and other coping strategies, (7) Thoughts about the future, (8) Autonomy and (9) Caregiver support.

DISCUSSION

This study provides important findings that will inform future interventions that aim to reduce or even prevent caregiver burden, as well as to inform healthcare professionals to recognize the needs of caregivers of people with YOPD.

U.S. Tax Credits to Promote Practical Proactive Preventative Care for Parkinson's Disease

Persons with Parkinson's disease (PD) and society at large can profit from a strategic investment into a forward leaning, practical, preventative, and proactive multidisciplinary care policy. The American healthcare system is not easily bent to accommodate this type of care, and thus a tax benefit is an attractive option. An individual federal income tax benefit of $6200 each year for every person residing in the US with a diagnosis of PD, could among other offerings provide monthly access to a licensed clinical social worker and access to mental health services. The implementation of more coordinated care has the potential reduce the burden of depression, anxiety, and demoralization. Personal training would also be covered and directed by physical and occupational therapists. The combination of home-based and telemedicine services would have the added benefit of improving access. The tax benefit would also provide access to a dietician. This type of care strategy could be designed to proactively identify early signs of aspiration and urinary tract infections to 'head off' significant morbidity. A $6200/year individual tax benefit for those diagnosed with PD will thus translate into more fall prevention, more care in the home setting, less hospitalizations, less depression, less anxiety, less demoralization, better diets, and less persons placed in nursing facilities. Additionally, this tax benefit will provide the potential for billions of dollars in savings to the healthcare system. A tax benefit for PD is a practical preventative and proactive strategy which can serve to advantage both this generation and the next.

Learning to PERSEVERE: A pilot study of peer mentor support and caregiver education in Lewy body dementia

BACKGROUND

Lewy Body Disease (LBD) is the second most common neurodegenerative disorder. Despite high family caregiver strain and adverse patient and caregiver outcomes, few interventions exist for LBD family caregivers. Based on a successful peer mentoring pilot study in advanced Parkinson's Disease, we revised the curriculum of this peer-led educational intervention incorporating LBD caregiver input.

OBJECTIVE

We assessed feasibility of a peer mentor-led educational intervention and its impact on LBD family caregivers' knowledge, dementia attitudes, and mastery.

METHODS

Using community-based participatory research, we refined a 16-week peer mentoring intervention and recruited caregivers online through national foundations. Experienced LBD caregiver mentors were trained and matched with newer caregiver mentees with whom they spoke weekly for 16 weeks, supported by the intervention curriculum. We measured intervention fidelity biweekly, program satisfaction, and change in LBD knowledge, dementia attitudes, and caregiving mastery before and after the 16-week intervention.

RESULTS

Thirty mentor-mentee pairs completed a median of 15 calls (range: 8-19; 424 total calls; median 45 min each). As satisfaction indicators, participants rated 95.3% of calls as useful, and at week 16, all participants indicated they would recommend the intervention to other caregivers. Mentees' knowledge and dementia attitudes improved by 13% (p < 0.05) and 7% (p < 0.001), respectively. Training improved mentors' LBD knowledge by 32% (p < 0.0001) and dementia attitudes by 2.5% (p < 0.001). Neither mentor nor mentee mastery changed significantly (p = 0.36, respectively).

CONCLUSIONS

This LBD caregiver-designed and -led intervention was feasible, well-received, and effective in improving knowledge and dementia attitudes in both seasoned and newer caregivers.

Association of caregiver strain with the trajectory of quality of life in Parkinson's disease

We aimed to identify caregiver characteristics associated with the trajectory of quality of life (QoL) in Parkinson's disease (PD). We fit a growth mixture model to longitudinal data from the Parkinson Foundation Parkinson's Outcomes Project (POP) to identify the heterogeneity of QOL trajectories in PD. We then used multinomial logistic regression to model baseline factors that predicted class membership. Baseline growth models were fit to QOL scores measured over 4 disease duration time points. A random intercept and slope model was determined to best fit the data. Next, growth mixture models (1, 2, 3, 4, and 5-class) were fit with covariates (Hoehn & Yahr, sex, and depression) and a three-class model was found to provide the best fit. Class 1 (problematic class (10.0%)) represented individuals with poor QOL at baseline and minor improvement over time. Class 2 (moderate class (32.6%)) represented individuals with moderate QOL at baseline with slight worsening over time. Class 3 (favorable class (56.9%)) represented individuals with good QOL at baseline and slight worsening over time. Multinomial regression revealed that lower caregiver strain, better mobility, and better verbal fluency at baseline predicted membership in the favorable compared to the moderate class. Worse mobility and younger age predicted membership in the problematic compared to the moderate class. While previous studies have reported on the association between mobility and cognition, the novel finding of an association between caregiver strain and PD QOL trajectory suggests caregiver strain is important to measure and address in future research and practice.

Psychometric investigation of the affiliate stigma scale in Mexican Parkinson's disease caregivers: Development of a short form

BACKGROUND

Parkinson's disease (PD) caregivers, particularly in Latin America, may experience high levels of affiliate stigma due to their association with a person having a disability. The most common measure used of this construct in the literature, the Affiliate Stigma Scale, was validated using non-standard and questionable methods.

OBJECTIVE

The purpose of this study was to investigate the factor structure and psychometric properties of the Spanish version of the Affiliate Stigma Scale with PD caregivers in Mexico using more widely accepted psychometric approaches including confirmatory and exploratory factor analyses (CFAs, EFAs).

METHODS

A sample of 148 PD caregivers from Mexico completed this measure, as well as indices of caregiver burden and anxiety.

RESULTS

Initial CFAs revealed that the data did not fit either the originally proposed one-factor or three-factor structures. An EFA was then conducted which was unable to discern any factor structure. Upon instituting a stepwise removal alpha-if-item-deleted process, a 5-item Affiliate Stigma Scale Spanish Short Form was retained with an adequate Cronbach's alpha, good convergent validity, and a Short Form CFA generally indicating adequate fit.

CONCLUSIONS

The new Spanish Affiliate Stigma Scale Short Form holds promise for more appropriately measuring affiliate stigma likely in general but particularly in Spanish and among PD caregivers. The Short Form can assist not only in assessing levels of caregiver affiliate stigma, but in creating novel interventions to help support caregivers and decrease stigma.

IN-HOME-PDCaregivers: The effects of a combined home visit and peer mentoring intervention for caregivers of homebound individuals with advanced Parkinson's disease

INTRODUCTION

Family caregivers of people with advanced Parkinson's Disease (PD) are at high risk of caregiver strain, which independently predicts adverse patient outcomes. We tested the effects of one year of interdisciplinary, telehealth-enhanced home visits (IN-HOME-PD) with 16 weeks of peer mentoring on caregiver strain compared with usual care.

METHODS

We enrolled homebound people with advanced PD (PWPD) and their primary caregiver as IN-HOME-PD dyads. We trained experienced PD family caregivers as peer mentors. Dyads received four structured home visits focused on advanced symptom management, home safety, medications, and psychosocial needs. Starting at approximately four months, caregivers spoke weekly with a peer mentor for 16 weeks. We compared one-year change in caregiver strain (MCSI, range 0-72) with historical controls, analyzed intervention acceptability, and measured change in anxiety, depression, and self-efficacy.

RESULTS

Longitudinally, IN-HOME-PD caregiver strain was unchanged (n = 51, 23.34 (SD 9.43) vs. 24.32 (9.72), p = 0.51) while that of controls worsened slightly (n = 154, 16.45 (10.33) vs. 17.97 (10.88), p = 0.01). Retention in peer mentoring was 88.2%. Both mentors and mentees rated 100% of mentoring calls useful, with mean satisfaction of 91/100 and 90/100, respectively. There were no clinically significant improvements in anxiety, depression, or self-efficacy.

CONCLUSIONS

Interdisciplinary telehealth-enhanced home visits combined with peer mentoring mitigated the worsening strain observed in caregivers of less advanced individuals. Mentoring was met with high satisfaction. Future caregiver-led peer mentoring interventions are warranted given the growing, unmet needs of PD family caregivers.

The impact of caregiving on quality of life in Parkinson's disease: A systematic review

OBJECTIVE

Parkinson's disease (PD) is a progressive neurodegenerative disease that can reduce quality of life (QOL). Previous research has explored patient specific factors that influence QOL; but understanding external factors that may also affect patient QOL, such as caregiver characteristics, can provide additional intervention targets that may improve QOL for both the person with PD and their caregiver.

METHODS

We conducted a systematic review of existing literature on caregiver factors that are related to QOL for the person with PD. We developed a tailored search strategy in six databases and performed a screening procedure according to PRISMA guidelines. We synthesized findings from articles that met inclusion criteria using a narrative approach and identified themes categorizing caregiver factors associated with PD QOL.

RESULTS

We found 32 full-text articles that fulfilled the inclusion criteria and passed the quality appraisal. Seven themes were identified, including: (1) burden, (2) strain, (3) QOL and satisfaction, (4) demographic factors, (5) psychological factors, (6) relationship factors, and (7) caregiver input.

CONCLUSIONS

Our review presents critical insights into the role of the caregiver in the QOL of a person with PD. Findings reveal several targets for intervention to improve QOL in this population.

Predictors of the change in burden, strain, mood, and quality of life among caregivers of Parkinson's disease patients

BACKGROUND AND OBJECTIVE

Caregiver burden in Parkinson's disease (PD) has been studied in many cross-sectional studies but poorly in longitudinal ones. The aim of the present study was to analyze the change in burden, strain, mood, and quality of life (QoL) after a 2-year follow-up in a cohort of caregivers of patients with PD and also to identify predictors of these changes.

PATIENTS AND METHODS

PD patients and their caregivers who were recruited from January/2016 to November/2017 from 35 centers of Spain from the COPPADIS cohort were included in the study. They were evaluated again at 2-year follow-up. Caregivers completed the Zarit Caregiver Burden Inventory (ZCBI), Caregiver Strain Index (CSI), Beck Depression Inventory-II (BDI-II), and EUROHIS-QOL 8-item index (EUROHIS-QOL8) at baseline (V0) and at 2-year follow-up (V2). General linear model repeated measure and lineal regression models were applied.

RESULTS

Significant changes, indicating an impairment, were detected on the total score of the ZCBI (p < 0.0001), CSI (p < 0.0001), BDI-II (p = 0.024), and EUROHIS-QOL8 (p = 0.002) in 192 PD caregivers (58.82 ± 11.71 years old; 69.3% were females). Mood impairment (BDI-II; β = 0.652; p < 0.0001) in patients from V0 to V2 was the strongest factor associated with caregiver's mood impairment after the 2-year follow-up. Caregiver's mood impairment was the strongest factor associated with an increase from V0 to V2 on the total score of the ZCBI (β = 0.416; p < 0.0001), CSI (β = 0.277; p = 0.001), and EUROHIS-QOL (β = 0.397; p = 0.002).

CONCLUSION

Burden, strain, mood, and QoL were impaired in caregivers of PD patients after a 2-year follow-up. Mood changes in both the patient and the caregiver are key aspects related to caregiver burden increase.

Peer Mentoring Program for Informal Caregivers of Homebound Individuals With Advanced Parkinson Disease (Share the Care): Protocol for a Single-Center, Crossover Pilot Study

BACKGROUND

Homebound individuals with advanced Parkinson disease (PD) require intensive caregiving, the majority of which is provided by informal, family caregivers. PD caregiver strain is an independent risk factor for institutionalization. There are currently no effective interventions to support advanced PD caregivers. Studies in other neurologic disorders, however, have demonstrated the potential for peer mentoring interventions to improve caregiver outcomes. In the context of an ongoing trial of interdisciplinary home visits, we designed and piloted a nested trial of caregiver peer mentoring for informal caregivers of individuals with advanced PD.

OBJECTIVE

The aim of this study was to test the feasibility of peer mentoring for caregivers of homebound individuals with advanced PD and to evaluate its effects on anxiety, depression, and caregiver strain.

METHODS

This was a single-center, 16-week pilot study of caregiver peer mentoring nested within a year-long controlled trial of interdisciplinary home visits. We recruited 34 experienced former or current family caregivers who completed structured mentor training. Caregivers enrolled in the larger interdisciplinary home visit trial consented to receive 16 weeks of weekly, one-to-one peer mentoring calls with a trained peer mentor. Weekly calls were guided by a curriculum on advanced PD management and caregiver support. Fidelity to and satisfaction with the intervention were gathered via biweekly study diaries. Anxiety, depression, and caregiver strain were measured pre- and postmentoring intervention at home visits 2 and 3.

RESULTS

Enrollment and peer-mentor training began in 2018, and 65 caregivers enrolled in the overarching trial. The majority of mentors and mentees were White, female spouses or partners of individuals with PD; mentors had a mean of 8.7 (SD 6.4) years of caregiving experience, and 33 mentors were matched with at least 1 mentee.

CONCLUSIONS

This is the first study of caregiver peer mentoring in PD and may establish an adaptable and sustainable model for disease-specific caregiver interventions in PD and other neurodegenerative diseases.

Understanding Caregiver Strain in Parkinsonism-A Mixed Methods Approach

BACKGROUND

Parkinsonism, including Parkinson's disease (PD) are progressive neurological conditions. As these condition progress, individuals will need more support with their care needs to maintain independent community-living. Care needs are mainly met by unpaid, informal caregivers, usually close family members or friends. Caregiver strain is thought to lead to the need for care home placement when the caregiver can no longer cope.

OBJECTIVE

To understand predictors of caregiver strain and its influence on care home placement for people with moderate to advanced Parkinsonism.

METHODS

This is a convergent mixed methods study. Quantitative data, following an adapted stress-appraisal model, were collected on caregiver profile, tasks performed and causes of caregiver strain. Semi-structured, in-depth interviews were conducted with caregivers of people with PD (PwP) who went into a care home during the study period, to develop a deeper understanding of the caregiver role and the factors influencing caregiver strain.

RESULTS

Quantitative data were collected from 115 patient caregiver dyads. Interviews were conducted with 10 caregivers. A model to predict caregiver strain was developed and predictors of caregiver strain were identified, such as functional disability and poor caregiver sleep.

CONCLUSION

Our findings further demonstrate the complexity of carer strain. Particular dimensions are identified that need to be addressed within clinical practice to reduce carer strain and support people with Parkinsonism to remain within their own home for as long as possible.

Caregiver "objective attitude" toward patients with neurodegenerative disease: Consequences for caregiver strain and relationship closeness

Many caregivers of patients with neurodegenerative disease experience physical and psychological strain, which is associated with negative health outcomes. Caregiver strain may be partly attributable to negative emotional responses (e.g.of resentment) to the behavioral, cognitive, and physical changes associated with patients' disease. The philosopher Peter Strawson observed that in dealing with people who have neurological impairments, we often choose to suspend such emotional responses, adopting what he labeled the "objective attitude," though this may come at the expense of our relationships with them. In this study, we assessed the mediating effect of caregivers' adoption of the objective attitude on caregiver strain and relationship closeness in the setting of disease progression. Caregivers of patients with neurodegenerative disorders (n = 215) completed the Clinical Dementia Rating, Relationship-Closeness scale, Caregiver Strain Index, and a novel questionnaire assessing the adoption of the objective attitude. A structural equation model assessing associations among these variables demonstrated good fit (χ² (88)=164.621, p < 0.001; CFI = 0.929, RMSEA = 0.064.) and showed that adoption of the objective attitude mediated the association between disease progression and relationship closeness (total β= -0.233, 95% CI: -0.351, -0.113; indirect β= -0.483, 95% CI: -0.602, -0.364; direct β = 0.250, 95% CI: 0.117, 0.384), but did not mediate the association between disease progression and caregiver strain (total β = 0.323, 95% CI: 0.234, 0.412; indirect β = 0.089, 95% CI: -0.027, 0.206; direct β = 0.153, 95% CI: -0.043, 0.349). For future work, we propose longitudinal measurements of these constructs to test the directionality of associations and consideration of how models for caregiver support can draw upon interdisciplinary insights.

Parkinson's Symptoms and Caregiver Affiliate Stigma: A Multinational Study

BACKGROUND AND OBJECTIVE

Research has documented the stigma that individuals with degenerative neurological diseases experience, but caregivers also experience stigma by association (i.e., affiliate stigma). In order to shed light on the stigma of caregivers of people with degenerative neurological diseases, the current study aimed to explore cross-cultural differences in the prevalence of Parkinson's disease (PD) caregiver affiliate stigma, as well as the relationship between PD symptoms and caregiver affiliate stigma. Applications for Alzheimer's disease are discussed.

METHODS

Survey data were collected in PD clinics at public, academic medical centers. Informal caregivers of an individual with PD from the US (n = 105) and from Mexico (n = 148) participated in the study. Caregivers completed a questionnaire that included the MDS Unified PD Rating Scale to describe the symptoms of the individual with PD, as well as the Affiliate Stigma Scale and demographic information.

RESULTS

A series of multiple regressions was run to examine whether PD symptoms were associated with affiliate stigma and if these differed by country. These regressions suggested that different patterns of PD symptoms predicted affiliate stigma in each country. Stigma was higher in the US compared to Mexico, and the relationship between bowel/bladder symptoms and affiliate stigma was significantly stronger in the US.

CONCLUSION

Symptoms of individuals with neurodegenerative diseases are related to affiliate stigma experienced by caregivers, and these relationships may differ cross-culturally. Negative public attitudes concerning bowl and bladder issues and the physical symptoms that accompany PD remain a source of stigma for caregivers and families, particularly in the US. Interventions for caregivers of individuals with neurodegenerative diseases should include strategies for coping with stigma concerning bladder and bowel problems, as well as other physical and mental health issues.

Longitudinal, Interdisciplinary Home Visits vs. Usual Care for Homebound People with Advanced Parkinson's Disease (IN-HOME-PD): Study protocol for a controlled trial

Background

The current understanding of advanced Parkinson disease (PD) and its treatment is largely based on data from outpatient visits. The most advanced and disabled individuals with PD are disconnected from both care and research. A previous pilot study among older, multimorbid patients with advanced PD demonstrated the feasibility of interdisciplinary home visits to reach the target population, improve care quality, and potentially avoid institutionalization.

Objective

The aim of this study protocol is to investigate whether interdisciplinary home visits can prevent a decline in quality of life of patients with PD and prevent worsening of caregiver strain. The protocol also explores whether program costs are offset by savings in health care utilization and institutionalization compared with usual care.

Methods

In this single-center, controlled trial, 65 patient-caregiver dyads affected by advanced PD (Hoehn and Yahr stages 3-5 and homebound) are recruited to receive quarterly interdisciplinary home visits over 1 year. The 1-year intervention is delivered by a nurse and a research coordinator, who travel to the home, and it is supported by a movement disorder specialist and social worker (both present by video). Each dyad is compared with age-, sex-, and Hoehn and Yahr stage–matched control dyads drawn from US participants in the longitudinal Parkinson’s Outcome Project registry. The primary outcome measure is the change in patient quality of life between baseline and 1 year. Secondary outcome measures include changes in Hoehn and Yahr stage, caregiver strain, self-reported fall frequency, emergency room visits, hospital admissions, and time to institutionalization or death. Intervention costs and changes in health care utilization will be analyzed in a budget impact analysis to explore the potential for model adaptation and dissemination.

Results

The protocol was funded in September 2017 and approved by the Rush Institutional Review Board in October 2017. Recruitment began in May 2018 and closed in November 2019 with 65 patient-caregiver dyads enrolled. All study visits have been completed, and analysis is underway.

Conclusions

To our knowledge, this is the first controlled trial to investigate the effects of interdisciplinary home visits among homebound individuals with advanced PD and their caregivers. This study also establishes a unique cohort of patients from whom we can study the natural course of advanced PD, its treatments, and unmet needs.

Contribution of neuropsychiatric symptoms in Parkinson's disease to different domains of caregiver burden

Introduction

Caregiver burden is high among caregivers of PD patients (CPD). Neuropsychiatric symptoms are leading contributors to CPD burden, but whether different symptoms differentially impact domains of caregiver burden is not known. Our objective was to examine which neuropsychiatric symptoms and demographic factors contribute to different domains of caregiver burden in PD.

Methods

This was a cross-sectional online survey study. Participants were recruited from the Fox Insight (FI) study and were eligible if they identified themselves as a CPD. The primary outcome was the Caregiver Burden Inventory (CBI) total score and its 5 sub-domain scores. The Neuropsychiatric Inventory Questionnaire (NPI-Q) assessed caregiver-reported neuropsychiatric symptoms in the care recipient. Multivariable linear regression models were used to characterize the associations between NPI-Q symptom severity scores and CBI scores. Covariates were caregiver age, sex, education, and caregiving duration.

Results

The sample consisted of 450 CPD, mean age 65.87 (SD 10.39) years, 74% females. After adjusting for covariates, CBI total score was predicted by NPI-Q total score (β = 1.96, p < 0.001); model adjusted R² = 39.2%. Anxiety severity had the largest effect size [standardized β (sβ) = 0.224] on the time-dependency domain, which was also associated with female sex (sβ = − 0.133) and age (sβ = 0.088). Severity of disinhibition (sβ = 0.218), agitation (sβ = 0.199), and female sex (sβ = 0.104) were associated with greater emotional burden.

Conclusion

Our findings indicate that demographic characteristics and specific neuropsychiatric symptoms contribute differentially to domains of caregiver burden. Tailored interventions to support CPD are needed.

Key Activities of Caregivers for Individuals With Parkinson Disease: A Secondary Analysis

BACKGROUND

Individuals with Parkinson disease (PD) require support from family caregivers because of decreased functional levels in a later stage. Much of the research with PD caregivers has been limited by relatively homogenous samples of primarily White and largely spousal caregivers.

METHODS

This secondary analysis aimed to describe a national sample of caregivers of individuals with PD in the Caregiving in the U.S. 2015 data set and their activities, including activities of daily living (ADLs), instrumental ADLs (IADLs), and key activities they performed for individuals with PD.

RESULTS

Fifty-four caregivers (32 women) were included. The mean (SD) age was 57.7 (16.9) years, and the sample included 57% White, 9% Black, 15% Asian, and 17% Hispanic caregivers. Relationships to care recipient were 32% spouses, 20% mothers, and 11% fathers, with the remaining being a variety of relationships. The number of ADLs and IADLs performed by the caregiver was 2.85 (SD, 2.18) and 4.72 (SD, 2.08), respectively. The most frequent ADLs were getting in and out of beds and chairs, getting dressed, getting to and from the toilet, and bathing/showering. The most frequent IADLs were transportation, shopping, managing finances, giving medicine, preparing meals, and housework.

CONCLUSION

This study shows the number of ADLs and IADLs performed by a diverse group of PD caregivers and indicates the need to acknowledge the extensive work performed by caregivers.

Better quality of life and less caregiver strain in young-onset Parkinson's disease: a multicentre retrospective cohort study

BACKGROUND

Parkinson's disease (PD) is typically considered as a disease of the elderly. However, there is a sizeable subgroup of patients where PD starts at a younger age, known as young-onset PD (YOPD). We evaluated the differences in quality of life and caregiver strain between YOPD and later onset PD (LOPD) patients in a large cohort.

METHODS

In collaboration with the Parkinson Foundation Quality Improvement Initiative (PF-QII), we conducted a retrospective three-year analysis on 962 PD patients of the QII database (starting date May 2016). Of these, 272 patients had YOPD, and 690 had LOPD. The Parkinson's Disease Questionnaire-39 (PDQ-39) total score served as primary outcome measure. Furthermore, we analysed group differences in modified caregiver strain index (MCSI) total score, three cognition functions, and number of falls. A regression analysis adjusting for covariates was used to assess the association of age at onset with PDQ-39 and MCSI.

RESULTS

PDQ scores were better in YOPD patients, MCSI scores on social constraint were lower in YOPD patients, but scores on financial constraint were higher in this group. After adjusting for covariates, YOPD patients had better quality of life and less caregiver strain at all follow-up moments, but not at baseline. Decline over time for all outcomes was lower in the YOPD group compared to the LOPD group. Cognitive functioning and number of falls progressed slower in the YOPD group compared to the LOPD group.

CONCLUSION

Compared to LOPD patients, YOPD patients had a better quality of life, less caregiver strain, fewer falls and better cognitive functioning after their first follow-up visit, and also a slower decline over time.

Palliative Care for Parkinson's Spectrum Disorders: an Emerging Approach

Parkinson's spectrum disorders (PSD) are neurodegenerative parkinsonian conditions that carry a tremendous symptom burden. Palliative care is an interdisciplinary medical specialty that focuses on improving quality of life for patients and caregivers affected by serious life-limiting illnesses, at any stage of disease. Research and clinical programs into this emerging therapeutic approach remain limited. This review focuses on the role of palliative care in the treatment of patients with PSD. Gaps in knowledge and recommendations for future research are discussed.

Caregiver burden worsens in the second year after subthalamic nucleus deep brain stimulation for Parkinson's disease

BACKGROUND

Caregiver burden (CB) in Parkinson's disease (PD) does not improve in the short term after bilateral subthalamic nucleus (STN) deep brain stimulation (DBS), despite motor improvement. This may be due to increased caregiver demands after surgery or the possibility that DBS unresponsive non-motor factors, such as executive dysfunction, contribute to CB.

OBJECTIVE

To evaluate the trajectory of CB in year 2 following bilateral STN DBS surgery for PD, and to test whether post-operative CB changes correlate with changes in executive function in a subgroup with available neuropsychological testing.

METHODS

This retrospective analysis included 35 patients with PD whose caregivers completed the Caregiver Burden Inventory (CBI) at baseline and between 9 and 24 months after bilateral STN DBS. 14 of these patients had neuropsychological testing both at baseline and within 6 months of their follow up CBI assessment.

RESULTS

CBI scores showed worsened CB from baseline to follow-up (16.4-21.5, p = 0.006). There was no correlation between change in executive function and change in CBI in the smaller subsample.

CONCLUSION

CB worsens in the 2 years after bilateral STN DBS despite improvement in motor symptoms and is not associated with change in executive dysfunction in the setting of advancing PD. These findings have implications on pre-operative counselling for patients and caregivers considering DBS for PD.

The relationship between Parkinson's disease symptoms and caregiver quality of life

OBJECTIVE

Caregivers for individuals with Parkinson's disease (PD) can experience high burden, which underlies the importance of examining the needs of caregivers to be able to support them in the caregiving role. The current study aims to assess the relationships among PD symptoms and four measures of caregiver quality of life (QOL; i.e., personal and social activities, anxiety and depression, self-care, and strain).

METHOD

Data from 181 caregiver/care recipient dyads (N = 362) were collected at a multidisciplinary PD clinic in a public, academic medical center in the southeastern United States at the time of the care recipient's first neuropsychological evaluation.

RESULTS

All PD symptoms were positively correlated with each other, as were all forms of caregiver QOL, and all PD symptoms were associated with each measure of caregiver QOL. A series of regressions suggested that demographics and PD symptoms predicted all four types of caregiver QOL, explaining 33% of the variance in caregiver personal and social activities, 24% in anxiety and depression, 28% in self-care, and 36% in strain. Female caregivers and those who provided care to male care recipients generally had worse QOL. Greater PD-related symptoms including difficulties with mobility, decreased emotional well-being, and greater nonmotor functioning impairment were unique predictors of reduced caregiver QOL.

CONCLUSIONS

PD symptoms are robustly related to caregiver QOL, with mobility and nonmotor symptoms as the primary drivers of this relationship. Interventions for PD caregivers should include strategies for managing mobility and nonmotor symptoms, as well as their QOL effects on caregivers.

Establishing Predictive Criterion Validity of the Parkinson's Disease Caregiver Strain Risk Screen-10

BACKGROUND AND PURPOSE

Studies reveal that caring for persons with Parkinson's disease affects informal caregivers psychologically and physically, yielding negative impacts on caregiving abilities. The purpose was to establish predictive criterion validity of the Caregiver Strain Risk Screen-10 (CSRS-10), a tool designed to monitor risk for strain in informal caregivers of persons with Parkinson's disease.

METHODS

Caregivers (N = 137) of persons with Parkinson's disease completed surveys that included CSRS-10 and Pennebaker Inventory of Limbic Languidness, to measure strain risk and frequency of physical health symptoms, respectively.

RESULTS

Hierarchical regression indicated that higher CSRS-10 scores were predictive of greater frequency of physical health symptoms in caregivers.

CONCLUSIONS

The study established predictive criterion validity of CSRS-10, further demonstrating it as an effective evidence-based tool for assessing risk for strain in this informal caregiver population.

Everyday Occupations and Other Factors in Relation to Mental Well-Being among Persons with Advanced Parkinson's Disease

This cross-sectional study investigated performed activities and the level of satisfaction with everyday occupations among people (n = 67) with advanced Parkinson's disease (PD), and how these factors and experiences of social relationships were related to mental well-being. Managing one's hygiene and physical exercises were activities that the majority still performed, whereas few were engaged in work or other productive occupations. Perceived health problems and satisfaction with everyday occupations were important factors for mental well-being since satisfaction with everyday occupations may be an important focus for occupational therapists and other health professionals when supporting mental well-being among persons with advanced PD.

Disease severity and quality of life in homebound people with advanced Parkinson disease: A pilot study

Background

As Parkinson disease (PD) progresses, symptoms increase, quality of life (QoL) declines, and individuals may become homebound, often losing access to neurologic care. We aimed to determine whether facilitating expert in-home care could improve our understanding of disease progression, treatment options, and unmet needs in this vulnerable population, and whether such a model could mitigate decline in QoL.

Methods

Patients with PD meeting Medicare homebound criteria were eligible for quarterly interdisciplinary home visits over 12 months. Each visit entailed an evaluation by a movement disorders neurologist, social worker, and nurse, including history, examination, medication reconciliation, psychosocial evaluation, pharmacologic and nonpharmacologic management, and service referrals. Disease severity, as measured by the Unified Parkinson's Disease Rating Scale (UPDRS), and QoL using the Neuro-QoL were measured at visits 1 and 4.

Results

Of 27 enrolled patients, 23 completed 4 visits, with high retention and high patient- and caregiver-reported satisfaction. The mean age at baseline was 80.9 years (SD 7.8) with a mean total UPDRS of 65.0 (SD 20.0). After one year of home visits, total UPDRS worsened by a mean of 11.8 points (p < 0.01) without a change in any of 8 QoL domains (p = 0.19-0.95).

Conclusions

Homebound individuals with advanced PD receiving interdisciplinary home visits experienced no significant decline in QoL over 1 year, despite disease progression. Our findings highlight the disease severity and impaired QoL of the advanced, homebound PD population, and the potential for novel approaches to foster continuity of care.

Our findings highlight the disease severity and impaired QoL of the advanced, homebound PD population, and the potential for novel approaches to foster continuity of care.

Telephone interventions, delivered by healthcare professionals, for providing education and psychosocial support for informal caregivers of adults with diagnosed illnesses

BACKGROUND

Maintaining care for ill persons in the community is heavily dependent on support from unpaid caregivers. Many caregivers, however, find themselves in a caring role for which they are ill prepared and may require professional support. The telephone is an easily accessible method of providing support irrespective of geographical location.

OBJECTIVES

The objective of this review was to evaluate the effectiveness of telephone support interventions, delivered by healthcare professionals, when compared to usual care or non-telephone-based support interventions for providing education and psychosocial support for informal caregivers of people with acute and chronic diagnosed illnesses, and to evaluate the cost-effectiveness of telephone interventions in this population.

SEARCH METHODS

We searched the following databases from inception to 16 November 2018: the Cochrane Central Register of Controlled Trials (CENTRAL); MEDLINE; Embase; PsycINFO; ProQuest Dissertations and Theses A&I; and CINAHL Complete. We also searched 11 caregiver-specific websites, three conference links, and two clinical trial registries.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) (including cluster-RCTs) and quasi-RCTs. We excluded cross-over trials because of the high risk of carry-over effects from one intervention to another.

DATA COLLECTION AND ANALYSIS

Two authors independently screened citations against the review's inclusion criteria, extracted data, and assessed the included studies using the Cochrane 'Risk of bias' tool. The review's prespecified primary (quality of life and burden) and secondary outcomes (skill acquisition, psychological health, knowledge, health status and well-being, family functioning, satisfaction, and economic outcomes), where reported, were assessed at the end of intervention delivery and at short-term (≤ 3 months), medium-term (> 3 to ≤ 6 months) and longer-term time points (> 6 to 12 months) following the intervention. Where possible, meta-analyses were conducted, otherwise results were reported narratively.

MAIN RESULTS

We included 21 randomised studies involving 1,690 caregivers; 19 studies compared telephone support interventions and usual care, of which 18 contributed data to the analyses. Two studies compared telephone and non-telephone professional support interventions. Caregiver ages ranged from 19 years to 87 years across studies. The majority of participants were female (> 70.53%), with two trials including females only. Most caregivers were family members, educated beyond secondary or high school level or had the equivalent in years of education. All caregivers were based in the community. Overall risk of bias was high for most studies.The results demonstrated that there is probably little or no difference between telephone support interventions and usual care for the primary outcome of quality of life at the end of intervention (SMD -0.02, 95% CI -0.24 to 0.19, 4 studies, 364 caregivers) (moderate-certainty evidence) or burden at the end of intervention (SMD -0.11, 95% CI -0.30 to 0.07, 9 studies, 788 caregivers) (low-certainty evidence). For one study where quality of life at the end of intervention was reported narratively, the findings indicated that a telephone support intervention may result in slightly higher quality of life, compared with usual care. Two further studies on caregiver burden were reported narratively; one reported that telephone support interventions may decrease burden, the other reported no change in the intervention group, compared with usual care.We are uncertain about the effects of telephone support interventions on caregiver depression at the end of intervention (SMD -0.37, 95% CI -0.70 to -0.05, 9 studies, 792 caregivers) due to very low-certainty evidence for this outcome. Depression was reported narratively for three studies. One reported that the intervention may reduce caregiver depression at the end of intervention, but this effect was not sustained at short-term follow-up. The other two studies reported there may be little or no difference between telephone support and usual care for depression at the end of intervention. Six studies measured satisfaction with the intervention but did not report comparative data. All six reported high satisfaction scores with the intervention. No adverse events, including suicide or suicide ideation, were measured or reported by any of the included studies.Our analysis indicated that caregiver anxiety may be slightly reduced (MD -6.0, 95% CI -11.68 to -0.32, 1 study, 61 caregivers) and preparedness to care slightly improved (SMD 0.37, 95% CI 0.09 to 0.64, 2 studies, 208 caregivers) at the end of intervention, following telephone-only support interventions compared to usual care. Findings indicated there may be little or no difference between telephone support interventions and usual care for all of the following outcomes at the end of intervention: problem-solving, social activity, caregiver competence, coping, stress, knowledge, physical health, self-efficacy, family functioning, and satisfaction with supports (practical or social). There may also be little or no effect of telephone support interventions for quality of life and burden at short-term follow-up or for burden and depression at medium-term follow-up.Litttle or no difference was found between groups for any of the reported outcomes in studies comparing telephone and non-telephone professional support interventions. We are uncertain as to the effects of telephone support interventions compared to non-telephone support interventions for caregiver burden and depression at the end of intervention. No study reported on quality of life or satisfaction with the intervention and no adverse events were reported or noted in the two studies reporting on this comparison.

AUTHORS' CONCLUSIONS

Although our review indicated slight benefit may exist for telephone support interventions on some outcomes (e.g. anxiety and preparedness to care at the end of intervention), for most outcomes, including the primary outcomes, telephone-only interventions may have little or no effect on caregiver outcomes compared to usual care. The findings of the review were mainly based on studies with overall high risk of bias, and few participants. Further high-quality trials, with larger sample sizes are required.

Adaptação dos Familiares Cuidadores de Idosos com Doença de Parkinson: Processo de Transição

Resumo Descreveu-se e interpretou-se a repercussão da transição para o exercício do papel de cuidador em familiares de idosos com doença de Parkinson, à luz da teoria das Transições. O método exploratório de abordagem qualitativa foi empregado com 20 familiares cuidadores de idosos com doença de Parkinson. Emergiram como temas: tendo consciência e reconhecimento da doença de Parkinson na família; envolvendo-se com o processo de cuidar; tornando-se um familiar cuidador; percebendo as mudanças e diferenças significativas no estilo de vida; acontecimentos e pontos críticos envolvidos na adaptação ao papel. Constatou-se que a transição de familiares para o papel de cuidador inicia-se com a conscientização dos primeiros sintomas e do diagnóstico, envolvendo mudanças e caracterizando-se pelas ações de cuidar.

Assessment of Caregiver Burden in Huntington's Disease

Huntington's disease (HD) is a rare neurodegenerative disease associated with disability and loss of patient independence. The caregivers of HD patients are at high risk for burnout. We aimed to identify variables that impact caregiver burden, as measured by the Modified Caregiver Strain Index (MCSI) and the Huntington's disease Quality of Life Battery for Carers Short Form (HD-SF). Total functional capacity and being sole caregiver were significantly associated with higher caregiver burden via MCSI. There was not good correlation between MCSI and HDQoLC-SF. This study highlights the need for more research to effectively identify at-risk caregivers for early intervention.

Predictors of Caregiver Distress in the Community Setting Using the Home Care Version of the Resident Assessment Instrument

PURPOSE OF STUDY

The purpose of this study was to identify factors predictive of new onset and improved caregiver distress among informal caregivers providing assistance for clients receiving home care.

PRIMARY PRACTICE SETTINGS

Home care.

METHODOLOGY AND SAMPLE

The sample included 323,409 clients receiving home care from a Community Care Access Centre between March 2002 and March 2015 for whom data were available from two subsequent Resident Assessment Instrument-Home Care (RAI-HC) assessments. Separate multivariate logistic regression models were created for onset of and improvement in caregiver distress.

RESULTS

Variables that increase the odds in onset of caregiver distress included primary caregiver is not satisfied with support received from family and friends; client lives with primary caregiver; 65 years and older; has Alzheimer and other related dementia; has condition or disease that makes cognition, activities of daily living, mood, or behavior patterns unstable; took sedatives in the last 7 days; Method for Assigning Priority Levels (MAPLe) score 4 or more; demonstrates persistent anger; has difficulty using the telephone; is married; requires 20 hr or more of informal help weekly; and Clinical Risk Scale score 4 or more. Variables that increased the odds of improved caregiver distress include client now lives with other persons (as compared with 90 days ago); demonstrates good prospects for recovery; treatment changes in last 30 days; surgical wound; female; one or more hospital visits in last 90 days; greater number of months between RAI-HC assessments; and two or more hours of physical activities in the last 3 days. Variables that decreased the odds of improved caregiver distress (i.e., persistent distress) include MAPLe score 4 or more; persistent anger; difficulty using telephone; Alzheimer, related dementia; requires interpreter; and lives with primary caregiver.

IMPLICATIONS FOR CASE MANAGEMENT PRACTICE

Informal caregivers provide essential support for home care clients. Factors predictive of new onset and improved caregiver distress can be used by case managers for comprehensive care planning that addresses the collective needs of the client-caregiver dyad.

Understanding, Impact, and Communication of "Off" Periods in Parkinson's Disease: A Scoping Review

BACKGROUND

Off periods are a common and disabling symptom of Parkinson's disease. We reviewed published research on understanding, impact, and communication regarding off periods to identify issues warranting further research.

METHODS

We performed a scoping review, searching MEDLINE, EMBASE, Cochrane Library, CINAHL, and PsycINFO from 2006 to January 2018 for studies examining the impact of, understanding of, or communication about off periods.

RESULTS

Twenty-six papers met eligibility criteria. Twenty-three studies evaluated the impact or experience of off periods in patients, three evaluated the impact upon carepartners, two papers addressed understanding of off periods, one study evaluated communication about off periods, and three studies evaluated a facilitator of communication about off periods. The findings indicate that (1) off periods are among the most troublesome symptoms to patients and that their impact on activities is broad; (2) the understanding of off periods by patients, carepartners, and nurses may be suboptimal; and (3) questionnaires hold promise as a mechanism for facilitating communication given the findings that they may enhance the detection of off periods and are rated as useful by physicians. No studies evaluated interventions to promote knowledge about off periods, and no studies identified barriers of communication about off periods.

CONCLUSIONS

There is a paucity of knowledge regarding the lived experiences of off periods, particularly for carepartners. Additionally, little knowledge exists in the literature regarding understanding of and communication about off periods between patients or carepartners and treating physicians. Further research is required to explore these issues to ultimately improve the treatment of off periods.

Cognitive impairment in Parkinson's disease: a report from a multidisciplinary symposium on unmet needs and future directions to maintain cognitive health

People with Parkinson's disease (PD) and their care partners frequently report cognitive decline as one of their greatest concerns. Mild cognitive impairment affects approximately 20-50% of people with PD, and longitudinal studies reveal dementia in up to 80% of PD. Through the Parkinson's Disease Foundation Community Choice Research Award Program, the PD community identified maintaining cognitive function as one of their major unmet needs. In response, a working group of experts across multiple disciplines was organized to evaluate the unmet needs, current challenges, and future opportunities related to cognitive impairment in PD. Specific conference goals included defining the current state in the field and gaps regarding cognitive issues in PD from patient, care partner, and healthcare professional viewpoints; discussing non-pharmacological interventions to help maintain cognitive function; forming recommendations for what people with PD can do at all disease stages to maintain cognitive health; and proposing ideas for how healthcare professionals can approach cognitive changes in PD. This paper summarizes the discussions of the conference, first by addressing what is currently known about cognitive dysfunction in PD and discussing several non-pharmacological interventions that are often suggested to people with PD. Second, based on the conference discussions, we provide considerations for people with PD for maintaining cognitive health and for healthcare professionals and care partners when working with people with PD experiencing cognitive impairment. Furthermore, we highlight key issues and knowledge gaps that need to be addressed in order to advance research in cognition in PD and improve clinical care.

Interdisciplinary Home Visits for Individuals with Advanced Parkinson's Disease and Related Disorders

Parkinson's disease (PD) is a complex, multisymptom, neurodegenerative disease affecting primarily older adults. With progression, many individuals become homebound and removed from coordinated, expert care, resulting in excess morbidity, mortality, and healthcare expenditures in acute care settings and institutions. Home visit care models have achieved the triple aim of improving individual and population health while reducing costs in many frail, community-dwelling geriatric cohorts. This study details a novel, interdisciplinary home visit program specifically designed for individuals with PD and related disorders and their family caregivers built upon best practice principles in the care of multimorbid older adults. At each quarterly home visit, a movement disorders-trained neurologist, social worker, and nurse work in parallel with the individual and caregiver to complete a history, physical, detailed medication reconciliation, psychosocial needs assessment, and home safety assessment. A comprehensive, person-centered plan is agreed upon, referrals to community resources are made, standardized documentation is shared, and follow-up communication is instituted. In the first 2 years, 272 visits were conducted with 85 individuals who represent one of the oldest, most disabled PD populations reported. Satisfaction with and retention in the program were high. This study represents the first translation of the success of interdisciplinary and home-based geriatric care models to a population with a specific neurological disease. Preliminary evidence supports the need for such programs in vulnerable populations. Future studies will prospectively assess person-centered outcomes, the effect of using telemedicine on sustainability, and cost effectiveness.

Sex disparities in access to caregiving in Parkinson disease

OBJECTIVE

To compare access to caregiving between men and women with Parkinson disease (PD).

METHODS

This was a cross-sectional and longitudinal study among participants with PD enrolled in the National Parkinson Foundation Parkinson's Outcomes Project from 2009 to 2014 at 21 international sites. The primary outcome measures were presence of a caregiver at the baseline visit, caregiver burden as measured by the Multidimensional Caregiver Strain Index (MCSI) at baseline, and time to first paid caregiver.

RESULTS

A total of 7,209 participants (63% men, 37% women) with PD were evaluated. Men had a mean age of 66.0 (SD 9.8) years, and women had a mean age of 66.9 (SD 9.7) years. More men than women had a caregiver (88.4% vs 79.4%, p < 0.0001). Caregivers of men reported greater strain than those of women (MCSI score 19.9 vs 16.4, p < 0.0001). These differences persisted after controlling for age, disease stage, number of comorbidities, cognitive and mobility measures, and health-related quality of life. In addition, the odds of caregiver accompaniment at baseline visit were lower for women compared to men (odds ratio 0.76, 95% confidence interval [CI] 0.67-0.86), and women had a faster rate to using a paid caregiver than men (hazard ratio 1.76, 95% CI 1.35-2.28) after controlling for potential confounders.

CONCLUSIONS

Informal caregiving resources are lower for women than men with PD, despite the finding that their caregivers report less strain than those of men. In addition, women are more likely to use formal, paid caregivers. Strategies to improve access to caregiving, particularly for women, are needed.

The self-management balancing act of spousal care partners in the case of Parkinson's disease

BACKGROUND

Living with and caring for someone with chronic illness can lead to limitations in activity and social participation for the care partner. Past research emphasizes the importance of care partners taking care of themselves physically and emotionally so they can stay healthy to support the care recipient. There is little information regarding how the care partner takes care of their own social lives. The purpose of this study was to explore the concept of social self-management from the perspective of spousal care partners of people with Parkinson's disease.

METHOD

Twenty spousal care partners of people with Parkinson's disease were interviewed three times. A grounded theory approach informed data analysis.

RESULTS

Findings that emerged from the data focused on balance in activities, support, and emotions and were summarized into three main themes: (1) Activities: Caregiving and beyond; (2) Strategies to support self and spouse; and (3) Emotional impact: Burden and compassion.

CONCLUSION

This research shows that care partners want to retain social participation and provides support for the importance of addressing the socio-emotional needs of care partners of people with a chronic disease. Interventions that guide care partners to take care of their spectrum of needs may lead to healthier, positive relationships. Implications for rehabilitation The focus of rehabilitation is often on the person diagnosed with the chronic condition. Living with and caring for someone with a chronic illness, such as Parkinson's disease, can lead to limitations in activity and social participation for the care partner. Including care partners in the rehabilitation process is key to helping maintain their health and well-being. Learning caregiving and self-management strategies may help care partners support their loved ones while staying socially engaged.

Caregiver Experiences Across Three Neurodegenerative Diseases: Alzheimer’s, Parkinson’s, and Parkinson’s With Dementia

Objective: This article asks whether distinct caregiver experiences of Alzheimer’s disease (AD), Parkinson’s disease (PD), and Parkinson’s disease with dementia (PDD) spouses are accounted for by disease diagnosis or by a unique combination of symptoms, demands, support, and quality of life (QOL) cross disease groups. Method: One hundred five live-in spouse caregivers (71.4 ± 7 years) were surveyed for persons with AD (39%), PD (41%), and PDD (20%). A hierarchical cluster analysis organized caregivers across disease diagnosis into clusters with similar symptom presentation, care demands, support, and QoL. Results: Four clusters cut across disease diagnosis. “Succeeding” cared for mild symptoms and had emotional support. “Coping” managed moderate stressors and utilized formal supports. “Getting by with support” and “Struggling” had the greatest stressors; available emotional support influenced whether burden/depression was moderate or severe. The results remain the same when diagnostic category is added to the cluster analysis. Discussion: This study supports going beyond disease diagnosis when examining caregiver experiences.

A Comprehensive Approach to Care in Parkinson's Disease Adds Quality to the Current Gold Standard

BACKGROUND

Providing high-quality care for patients with Parkinson's disease (PD) involves addressing both motor and nonmotor features. We describe the implementation and evaluation of a 2-day, interdisciplinary Comprehensive Care Clinic (CCC) for patients with PD.

METHODS

Patients who attended the CCC between January 2010 and July 2013 were matched by sex and age with patients who were evaluated in specialist care during the same time frame. Provider documentation of the American Academy of Neurology (AAN) quality measures for PD and Unified Parkinson's Disease Rating Scale (UPDRS) motor scores were compared between specialist and CCC visits at baseline and at 12 months.

RESULTS

Ninety-five patients participated in the CCC (60% men; 75% white; mean age, 68 years; age range, 38-97 years). Of these, 29 patients were matched to specialist care patients based on the availability of 12-month follow-up data. Both groups were similar with respect to race, marital status, years with PD, and baseline UPDRS motor scores. On average, patients who received CCC care met 10 of 10 AAN quality measures, whereas those who received specialist care met only 5 of 10 quality measures (P < 0.001) over 12 months. At 12-months, there were no significant differences in UPDRS motor scores between the groups (P = 0.5).

CONCLUSIONS

According to the AAN quality measures, the CCC provided higher quality care than the gold standard of specialty care. A randomized controlled trial of the CCC model is warranted to determine its impact on patient-centered outcomes and to assess whether the standard model of care should be altered.

Caregiver Burden in Parkinson Disease: A Critical Review of Recent Literature

Burden is a negative psychological state induced in caregivers by the demands of providing care to a person with an illness or a disability. Managing caregiver burden in Parkinson disease (PD) is significant because informal caregivers make a substantial contribution to the well-being of persons with PD, incurring financial, social, and personal losses. Failure to recognize and manage caregiver burden may lead to burnout and premature institutionalization of the person with PD. We conducted a comprehensive literature review to identify and summarize factors that may amplify burden, including motor and nonmotor symptoms of PD, caregiver psychiatric symptoms, and caregiver coping style. We review instruments designed to sample the construct of burden among caregivers and evaluate interventions that may reduce burden, either by directly targeting caregivers or by treating PD symptoms associated with burden. We aim to provide a concise synopsis of these issues for the clinician or researcher working with this population in order to facilitate recognition of caregiver burden, provide accurate assessment, administer appropriate interventions, and stimulate further research in this area.

Clinical Management of Drug-Induced Dyskinesia in Parkinson’s Disease: Why Current Approaches May Need to Be Changed to Optimise Quality of Life

Parkinson’s disease is a complex, progressive neurodegenerative disorder associated with both motor and non-motor symptoms. Current treatment strategies mainly target the alleviation of motor symptoms through dopaminergic replacement therapy. Many patients with Parkinson’s disease will eventually experience motor complications associated with their anti-parkinsonian medication. One of those complications is drug-induced dyskinesia. This paper firstly reviews current approaches to the management of drug-induced dyskinesia, from modifications to the titration of medication, to more invasive approaches like deep brain stimulation. Following this we describe a recent proposal suggesting that the treatment of dyskinesia should be based on the impact on daily activities of patients rather than on the mere presence of the condition. Next, we discuss how this approach could improve the quality of life of patients and their caregivers and finally, we suggest possible ways of implementing this approach in practice.

Strategies to maintain quality of life among people with Parkinson's disease: what works?

Among chronic neurodegenerative disorders, Parkinson's disease (PD) is one of the most difficult and challenging to tackle as several motor and nonmotor features influence the patients' quality of life (QoL) and daily activities. Assessing patients QoL with valid instruments and gathering knowledge about the determinants that affect QoL in individuals with PD are the basis of an efficient caring strategy. In addition to the known motor symptoms, nonmotor disorders must also be comprehensively tracked and targeted for treatment to enhance QoL. A holistic strategy to maintain QoL in people with PD should consist of a multidisciplinary, personalized and patient-centered approach with timely administration of palliative care and efficient involvement of caregivers and family members.

COPPADIS-2015 (COhort of Patients with PArkinson's DIsease in Spain, 2015), a global--clinical evaluations, serum biomarkers, genetic studies and neuroimaging--prospective, multicenter, non-interventional, long-term study on Parkinson's disease progression

Background

Parkinson’s disease (PD) is a progressive neurodegenerative disorder causing motor and non-motor symptoms that can affect independence, social adjustment and the quality of life (QoL) of both patients and caregivers. Studies designed to find diagnostic and/or progression biomarkers of PD are needed. We describe here the study protocol of COPPADIS-2015 (COhort of Patients with PArkinson’s DIsease in Spain, 2015), an integral PD project based on four aspects/concepts: 1) PD as a global disease (motor and non-motor symptoms); 2) QoL and caregiver issues; 3) Biomarkers; 4) Disease progression.

Methods/design

Observational, descriptive, non-interventional, 5-year follow-up, national (Spain), multicenter (45 centers from 15 autonomous communities), evaluation study. Specific goals: (1) detailed study (clinical evaluations, serum biomarkers, genetic studies and neuroimaging) of a population of PD patients from different areas of Spain, (2) comparison with a control group and (3) follow-up for 5 years. COPPADIS-2015 has been specifically designed to assess 17 proposed objectives. Study population: approximately 800 non-dementia PD patients, 600 principal caregivers and 400 control subjects. Study evaluations: (1) baseline includes motor assessment (e.g., Unified Parkinson’s Disease Rating Scale part III), non-motor symptoms (e.g., Non-Motor Symptoms Scale), cognition (e.g., Parkinson’s Disease Cognitive Rating Scale), mood and neuropsychiatric symptoms (e.g., Neuropsychiatric Inventory), disability, QoL (e.g., 39-item Parkinson’s disease Quality of Life Questionnaire Summary-Index) and caregiver status (e.g., Zarit Caregiver Burden Inventory); (2) follow-up includes annual (patients) or biannual (caregivers and controls) evaluations. Serum biomarkers (S-100b protein, TNF-α, IL-1, IL-2, IL-6, vitamin B12, methylmalonic acid, homocysteine, uric acid, C-reactive protein, ferritin, iron) and brain MRI (volumetry, tractography and MTAi [Medial Temporal Atrophy Index]), at baseline and at the end of follow-up, and genetic studies (DNA and RNA) at baseline will be performed in a subgroup of subjects (300 PD patients and 100 control subjects). Study periods: (1) recruitment period, from November, 2015 to February, 2017 (basal assessment); (2) follow-up period, 5 years; (3) closing date of clinical follow-up, May, 2022. Funding: Public/Private.

Discussion

COPPADIS-2015 is a challenging initiative. This project will provide important information on the natural history of PD and the value of various biomarkers.

Reaching Those Most in Need - A Call to Action for Advanced Parkinson's Disease

Much of the clinical and research attention for Parkinson's Disease (PD) has focused on mild to moderate stages. As the disease advances, it can become difficult for patients to attend clinical visits. These patients are often lost to follow-up, and consequently, vanish from the pool of potential research subjects who could inform our management of this understudied population. We aim to increase awareness about this population and potential interventions to improve continuity of care and foster research in advanced PD.

Associations and implications of low health literacy in Parkinson's Disease

BACKGROUND

Low health literacy (HL) indicates a limited ability to understand and use basic information to make appropriate healthcare decisions. While low HL is associated with higher morbidity, mortality, and healthcare costs in multiple chronic conditions, little is known about HL and its associations in Parkinson's disease (PD).

METHODS

Cross-sectional study of non-demented adults with PD participating in the National Parkinson Foundation Parkinson's Outcomes Project at the University of Pennsylvania. Subjects were administered two brief HL assessments-the Rapid Estimate of Adult Literacy in Medicine-Short Form (REALM-SF), a word-recognition test, and the Newest Vital Sign (NVS), a test of literacy, numeracy and understanding of health information-as well as demographic and clinical questionnaires. Adverse outcomes included falls in the 3 months preceding the study visit, and hospital admissions, emergency room visits, infections, or injuries in the preceding year. Caregiver burden was measured using the Multidimensional Caregiver Strain Index.

RESULTS

168 subjects completed both HL screens (mean 65.8 years, 65.5% male, 65.2% Hoehn & Yahr Stage 2). Using the REALM-SF, 97.6% of subjects had adequate HL. Using the NVS, however, 29.8% had low HL, which was associated with older age, lower education, male gender, greater disease severity, and poorer cognition. Low HL was associated with hospital admission and increased caregiver burden.

CONCLUSIONS

Low HL is common and associated with greater caregiver burden and a higher likelihood of hospitalization in patients with PD. Since HL is associated with both disease severity and adverse outcomes, it may be an important, modifiable contributor to morbidity.

Factors contributing to caregivers' stress and burden in Parkinson's disease

BACKGROUND AND OBJECTIVE

To analyze the main determinants of burden and stress in caregivers of Spanish Parkinson's disease (PD) patients.

METHODS

One-hundred and twenty-one non-demented patients with PD (57.9% males; 70.9 ± 8.2 years old) were included in this cross-sectional, monocenter, evaluation study. Caregivers (n = 121; 71.9% females; 60.2 ± 15 years old) were assessed using the Zarit Caregiver Burden Inventory (ZCBI) and Caregiver Strain Index (CSI). Multiple linear regression methods were used to evaluate factors contributing to caregivers' stress and burden: (i) PD motor dysfunction (ON-state Hoehn & Yahr/Unified Parkinson's Disease Rating Scale [UPDRS] part III and motor complications [UPDRS part IV]); (ii) Mood (Beck Depression Inventory [BDI]); (iii) Non-motor symptoms (Non-Motor Symptoms Scale [NMSS]); (iv) Disability (Schwab & England Activities of Daily Living Scale [ADLS]); and (v) Socio-demographic and other disease-related variables.

RESULTS

Zarit Caregiver Burden Inventory and CSI mean scores were 16 ± 13.9 and 2.1 ± 2.3, respectively. High correlation was found between ZCBI and CSI (r = 0.819; P < 0.0001). Moderate to severe burden (ZCBI > 40) was present in 9.1% of caregivers; 5.8% had high levels of stress (CSI ≥ 7). Moderate to strong correlations were observed between patient-related variables (Hoehn&Yahr, UPDRS-III, UPDRS-IV, BDI, NMSS, and ADLS) and ZCBI and CSI (P < 0.0001). Linear regression methods showed that ADLS had the strongest influence on ZCBI and CSI, followed by BDI on ZCBI.

CONCLUSIONS

Disability (ADLS) and mood (BDI) of patients with PD are the main factors contributing to burden and stress in caregivers.
