Abstract
Background Because dementia is a long-term condition, the appropriate involvement of health-care professionals is considered important. However, little is known about the factors associated with changes in family caregiver burden. Objective To clarify changes in family caregiver burden and associated factors during follow-up at a memory clinic. Methods A retrospective cohort study was conducted, enrolling 495 pairs of patients with dementia or mild cognitive impairment and their family caregivers. A total of 120 pairs completed the second evaluation. The caregiver burden was assessed using the Zarit Burden Interview (ZBI). Data at the initial visit and after an average follow-up of about 2 years were compared and analyzed. Results At initial visit, the patients' mean age, Mini-Mental State Examination (MMSE) and ZBI scores were 78.6±5.6 years, 23.3±3.5, and 22.6±16.7, respectively. At follow-up, MMSE scores decreased (21.4±4.5, p < 0.001), but ZBI scores remained similar (22.5±13.6). When the difference in ZBI scores between the two time points was defined as ΔZBI, and the related factors were analyzed by multiple regression analysis, ZBI scores at the initial visit, start of psychotropic drug, and decrease of neuropsychiatric symptoms were identified as significant factors (p < 0.001, p = 0.003, p < 0.001, respectively). A significant negative correlation was found between ZBI scores at the initial visit and ΔZBI (r = -0.588, p < 0.001). Conclusions These findings suggest the importance of assessing changes in the burden experienced by family caregivers during the disease follow-up.

Abstract
BACKGROUND Many individuals with Alzheimer's disease (AD) are dependent on nonprofessional care partners. Providing informal care can result in emotional, physical, and financial burdens; however, there is a need for a better understanding of the impact of AD on care partners to support the clinical and economic assessment of potential new treatments. OBJECTIVE We conducted a literature review to evaluate the burden experienced by care partners of individuals with AD. METHODS Electronic screening and supplementary searches identified studies published from 2011 to 2022 describing the association between AD and the quality of life (QoL) and physical health of care partners, and the economic or financial burden of AD. RESULTS Following electronic screening, 62, 25, and 39 studies were included on care partner burden, cost, and healthcare resource use in AD, respectively. Supplementary searches identified an additional 32 studies, resulting in 149 unique studies. These studies showed that care partners of individuals with AD report moderate to severe burden. Higher burden and lower QoL were observed in those caring for individuals with more severe AD. Care partners of individuals with AD experience higher burden, lower QoL, and higher levels of stress, depression, and anxiety than those without caring responsibilities. Informal care costs increased with AD severity and accounted for the greatest proportion of overall societal cost. CONCLUSIONS Care partners of individuals with AD experience emotional and economic burden, which increases with AD severity. These impacts should be quantified comprehensively in future studies and captured in economic evaluations of AD interventions.

Group Psychotherapy for Parents of Youth with Pediatric Acute-Onset Neuropsychiatric Syndrome. J Clin Psychol Med Settings 2022:10.1007/s10880-022-09926-0.

Abstract
Parents of children with diagnoses of Pediatric Acute-onset Neuropsychiatric Syndrome (PANS) and Pediatric Autoimmune Neuropsychiatric Disorder Associated with Streptococcal Infections (PANDAS) may experience significant psychological distress related to their child's severe and relapsing illness and challenges with the traumatic nature of its treatment. No manualized or studied psychological interventions specifically for parents of youth with PANS have existed prior to this study. In this pilot study, we assessed the feasibility, satisfaction, and treatment fidelity of a brief 9-session group therapy intervention for parents based on principles of trauma-focused cognitive behavior therapy (CBT). We hypothesized that, if initially elevated, symptoms of depression, anxiety, and trauma would decrease and participants' utilization of positive coping mechanisms would increase post-intervention. We adapted an existing evidence-based group intervention developed for parents of children with premature infants to target sources of stress and coping in parents of children with PANS. Ten parents participated in the study. The 9-session intervention used a combination of techniques that included cognitive restructuring, coping skills, self-care, and a trauma narrative to address psychological stress, trust, grief, and unwanted emotions. Outcome measures included parental symptoms of anxiety, depression, and posttraumatic stress disorder (PTSD), as well as rating of parental satisfaction with the intervention. The treatment was feasible and deliverable with high fidelity. The intervention was rated as useful and satisfactory by parents (overall average usefulness of 4.54 and satisfaction of 4.71 out of 5.0). Elevated symptoms of PTSD and depression decreased with large effect sizes (Cohen's d = 1.42 and Cohen's d = 1.38, respectively). Participating parents demonstrated significantly more active coping and acceptance behaviors and stances. A brief 9-session group therapy intervention based on principles of trauma-focused CBT was found to be effective in reducing symptoms of psychological distress in parents of children with PANS.

Abstract
Dementia is a progressive disease that puts substantial strain on caregivers. Many persons with dementia (PwDs) receive care from a relative. Since male and female caregivers experience different issues related to stress, it is important to meet their different needs to prevent the early nursing home placement of PwDs. This study investigated the multifactorial aspects of caregiver burden and explored gender differences in caregiver burden in a rural setting. This was a cross sectional study that administered anonymous questionnaires to family caregivers of PwDs. Caregiver burden was assessed using the Burden Scale for Family Caregivers-short version. A path model was used to determine the multivariate associations between the variables. To reflect the multifaceted aspects of caregiver burden, we used Pearlin's model with its four dimensions. A total of 113 family caregivers responded to our survey. The overall burden of caregivers was moderate. According to the path model, gender differences were predictors of caregiver burden. The behaviour of the person with dementia and cohabitation had direct effects on caregiver burden. Our results suggest that the experiences of men and women caring for a PwD are different and highlight the need for tailored support in dementia care.

Abstract
BACKGROUND Caring for a patient with end-stage kidney disease (ESKD) is highly stressful and can impact negatively on the physical and psychological well-being of caregivers. To accurately assess caregiver burden (CB), health care providers (HCPs) need to identify characteristics associated with an increase in CB. AIM The aim of this review is to explore CB in caregivers of adult patients with ESKD and to identify characteristics associated with any increase in CB. METHOD A comprehensive literature search was completed using five electronic databases. Medline, Embase, CINHAL, PsycINFO, and Scopus. The Joanna Briggs Institute checklist (JBI) was used to quality appraise full text papers included in the review. No time limit for the date of publication of studies was employed, to enable the inclusion of more extensive literature. RESULTS A total of 38 relevant studies from 18 countries were identified and included in the review. A variety of patient and caregiver factors can impact positively or negatively on CB, including socio-demographic factors of patients and caregivers, disease-related factors, situational and relational factors, environmental factors, and psychological factors. CONCLUSION This review provides awareness to HCPs of the important factors associated with CB, when assessing or targeting interventions for caregivers experiencing burden.

Abstract
Background: Caring for patients with dementia at home is often a long-term process, in which the independence of the patient declines, and more responsibility and supervision time is required from the informal caregiver. Objective: In order to minimize and reduce caregiver burden, it is important to explore its trajectory and the accompanying risk factors as dementia progresses; the objective of this systematic review. Methods: PRISMA guidelines were followed in this systematic review. Three databases, PubMed, PsycINFO, and EMbase, were systematically searched in November 2019 using specific keywords. Results: 1,506 hits emerged during the systematic search but only eleven articles actually met the inclusion criteria for this review. The trajectory of caregiver burden is highly variable and depends on multiple factors. Important risk factors included: patients’ behavioral and neuropsychiatric symptoms, and their decline in functioning in (I)ADL; the caregiver’s age, gender, and physical and mental health; and, within the dyads (patient/caregiver), cohabitation and kinship. Conclusion: There is no one-size-fits-all for predicting how caregiver burden will change over time, but specific factors (like being a spouse and increased behavioral impairment and decline in functional status in the patient) may heighten the risk. Other factors, not yet comprehensively included in the published studies, might also prove to be important risk factors. Future research in the field of reducing caregiver burden is recommended to integrate the patient, caregiver, and context characteristics in the trajectory of caregiver burden, and to assess more clearly the phase of the dementia progression and use of external resources.

Abstract
OBJECTIVE To identify, in caregivers of patients with Alzheimer's disease (AD) dementia, factors associated with subjective (personal, physical, emotional, and social) and objective (informal caregiver time and costs) caregiver burden. DESIGN Prospective longitudinal European observational study: post-hoc analysis. SETTING Clinic. PARTICIPANTS Community-dwelling patients in France and Germany aged ≥ 55 years (n = 969) with probable AD and their informal caregivers. MEASUREMENTS Mini-Mental State Examination (MMSE), Alzheimer's Disease Cooperative Study-Activities of Daily Living (ADCS-ADL), 12-item Neuropsychiatric Inventory (NPI-12), Zarit Burden Interview (ZBI), informal caregiver basic and instrumental ADL hours (Resource Utilization in Dementia instrument), and informal caregiver costs. Mixed-effect models of repeated measures (MMRM) were run, including baseline and time-dependent covariates (change from baseline [CFB] to 18 months in MMSE, ADCS-ADL, and NPI-12 scores) associated with CFB in ZBI score/informal caregiver time over 36 months (analyzed using linear regression models) and informal caregiver costs over 36 months (analyzed using generalized linear models). RESULTS Greater decline in patient function (ADCS-ADL) over 18 months was associated with increased subjective caregiver burden (ZBI), hours, and costs over 36 months. Increased behavioral problems (NPI-12) over 18 months also negatively impacted ZBI. Cognitive decline (MMSE) over 18 months did not affect change in caregiver burden. CONCLUSIONS Long-term informal caregiver burden was driven by worsening functional abilities and behavioral symptoms but not cognitive decline, over 18 months in community-dwelling patients with AD dementia. Identifying the drivers of caregiver burden could highlight areas in which interventions may benefit both caregivers and patients.

Stress-related vulnerability and usefulness of healthcare education in Parkinson's disease: The perception of a group of family caregivers, a cross-sectional study. Appl Nurs Res 2019; 51:151186.

Abstract
Parkinson's Disease is associated with a high assistive complexity, thus generating in caregivers a burden proportional to the intensity of the care provided. This study aims to evaluate whether the stress-related level of caregivers is related to their perception of the need for healthcare education. A cross-sectional study was conducted on 69 family caregivers that completed the Stress-related Vulnerability Scale (SVS scale) with a tool of proposed interventions stratified according to caregivers' need as "nothing", "somewhat", "moderately" and "extremely". A direct association between the SVS scale and the perception of the usefulness of interventions was detected, and significant differences were observed for "Caregivers tele-support group" and "Peer-led support group" interventions, thus suggesting an important role for caregivers' emotional status in considering of training courses. Caregivers are split between low vulnerability, with minimal perception of training need, and high burden state with the acute necessity of support to manage patients.

Abstract
Chronic diseases are mostly managed by family caregivers that often face the "caregiver burden". This study aimed to understand whether a multidisciplinary theoretical-practical training course could influence the burden, health literacy and needs of caregivers. Seventy-six familial caregivers were asked to complete the Caregiver Burden Inventory-CBI, Caregiver Needs Assessment-CNA, and Health Literacy Questionnaire-HLQ, before and after the course. A significant decrease in CBI and an increase of CNA were observed. However, a significantly higher rate of CBI decrease and a lower increase of CNA were detected in the neurological compared to the oncological group (p = 0.001). Moreover, the ability of the participants to look for and find health information significantly improved. The course contrasted caregivers' burden, increased their search for health information, and revealed their requiring of training and emotional and social support. Caregiver education plays a pivotal role in the management of chronic patients, enhancing the quality of life of both patients and caregivers.

Abstract
OBJECTIVES The aims of the study were to identify the clinical characteristics of three groups of caregivers: spouses, live-in adult-child or non-live-in adult-child, and their relation to the degree of perceived burden (Caregiver Burden Interview). METHODS The sample comprised 275 Alzheimer's disease primary caregivers, with a follow-up of 24 months. Cognitive, functional and behavioural characteristics were evaluated in persons with dementia, whilst sociodemographic data, use of socio-medical resources, physical and mental health and self-perceived burden were assessed in caregivers. Generalized estimating equations were used for longitudinal data analysis. RESULTS Spouse caregivers were 45.0% men, sole caregivers (>80%), used few external resources and had worse physical health. The number of female adult-child caregivers was higher (>75%). The live-in adult-child group, compared with the non-live-in adult-child group, was less likely to be married, had a lower level of education, was more commonly the sole caregiver and used fewer external resources. The greatest burden was observed in live-in adult-child caregivers, and the lowest in the non-live-in adult-child group, with no significant variation in the follow-up for both groups. Spouses had an intermediate level of perceived burden, which rose significantly during follow-up (p < 0.001). CONCLUSIONS Kinship and cohabitation with the persons with dementia were associated with different scores and evolution of the burden, with an increase in the follow-up of the spouses, and with more or less burden, depending on cohabitation, in the adult-child groups. Interventions to reduce the level of burden on caregivers should consider these differences. Copyright © 2017 John Wiley & Sons, Ltd.
