Characteristics of Changes in Caregiver Burden during Follow-up at a Memory Clinic: A Retrospective Cohort Study. J Alzheimers Dis Rep 2024; 8:151-162. [PMID: 38405344 PMCID: PMC10894603 DOI: 10.3233/adr-230069] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2023] [Accepted: 12/26/2023] [Indexed: 02/27/2024] Open
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.

Evaluating Elements of the Care Partner Experience in Individuals Who Care for People with Alzheimer's Disease Across the Severity Spectrum. Neurol Ther 2024; 13:53-67. [PMID: 37889399 PMCID: PMC10787717 DOI: 10.1007/s40120-023-00558-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/18/2023] [Accepted: 10/13/2023] [Indexed: 10/28/2023] Open
Abstract
INTRODUCTION Non-professional care partners play an important and often evolving role in the care of persons living with Alzheimer's disease (PLWAD). We investigated two elements of the care partner experience, namely time and strain incurred by care partners providing care to PLWAD across the severity spectrum. METHODS Data gathered from the Alzheimer's Disease Patient and Caregiver Engagement (AD PACE) What Matters Most (WMM) study series were analyzed to determine how much time care partners spent providing care to PLWAD based on where the care recipients lived. Additionally, quantitative assessments of weekly hours providing care and the strain experienced by care partners were conducted using the UsAgainstAlzheimer's A-LIST Insights Series survey, which included the Modified Caregiver Strain Index (MCSI). Finally, a targeted literature review was conducted to contextualize findings and characterize the existing literature landscape. RESULTS Care partners in the AD PACE WMM studies (n = 139) spent significantly more hours providing care for recipients who lived with someone (mean ± standard deviation [SD], 57.3 ± 44.3 h/week) than for recipients who lived alone (26.0 ± 12.0 h/week) (P = 0.0096) or lived in assisted living/nursing home (23.6 ± 14.4 h/week) (P = 0.0002). In the A-LIST Insights Series survey, care partners provided an overall mean (± SD) 58.1 ± 53.0 h of direct care each week, with caregiving hours increasing with increasing severity of AD/AD-related dementias (AD/ADRD). Additionally, care partners for recipients with mild (n = 14), moderate (n = 111), and severe AD/ADRD (n = 91) had overall mean MCSI scores of 9.0 ± 3.8 (range 2-14), 13.3 ± 4.8 (range 4-23), and 17.5 ± 5.3 (range 4-26), respectively, with higher scores suggesting greater care partner strain. CONCLUSIONS Persons living with AD require increasing levels of care along the spectrum of disease, and even individuals with early disease need care from partners. Early interventions that slow progression of AD and programs that improve family function may have beneficial impact on the experiences of care partners for recipients with mild, moderate, or severe AD.

Physical activity together for couples living with mild cognitive impairment (PAT-MCI): A feasibility study. Geriatr Nurs 2024; 55:221-228. [PMID: 38035459 DOI: 10.1016/j.gerinurse.2023.11.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2023] [Revised: 11/10/2023] [Accepted: 11/14/2023] [Indexed: 12/02/2023]
Abstract
Mild cognitive impairment is a prodromal phase of Alzheimer's disease and related dementias. Cognitive and/or neuropsychiatric symptoms that could worsen over time cause challenges for patients and romantic partners, who often assume the role of informal caregivers. Although physical activity is beneficial, older adults with mild cognitive impairment and their romantic care partners are generally physically inactive. Our 16-week study was performed to see whether physical activity together is feasible to increase physical activity among four dyads (individuals with mild cognitive impairment and their spouses). Our dyadic intervention was feasible given more than 70 % of participants self-reported adherence to physical activity based on the guidelines for adults in the United States. In exit interviews, togetherness was highlighted as one of the biggest strengths of this study. Future studies with more representative samples are needed, as well as adopting a more tailored approach that accounts for individuals' levels of physical fitness.

Association Between Self- and Proxy-Reported Depression and Quality of Life in Mild-Moderate Alzheimer's Disease. Am J Geriatr Psychiatry 2024; 32:58-67. [PMID: 37827916 PMCID: PMC10843510 DOI: 10.1016/j.jagp.2023.08.004] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Revised: 08/08/2023] [Accepted: 08/08/2023] [Indexed: 10/14/2023]
Abstract
OBJECTIVE Prior studies have reported an association between depression and quality of life (QOL) in Alzheimer's disease (AD), but the effect of self- versus proxy rating of mood and QOL has not been described. DESIGN In this secondary analysis of data from a cohort study, the authors used a linear mixed-effects model to determine if the association between depression and QOL is affected by whether both measures are assessed by the same member of the patient-caregiver dyad. SETTING Participants and caregiver informants were recruited from 10 California Alzheimer Disease Centers. PARTICIPANTS A total of 137 participants with mild-to-moderate Alzheimer's disease and their caregivers. MEASUREMENTS Self- and proxy-rated scores on both the Geriatric Depression Scale (GDS) and the Quality of Life in Alzheimer's Disease scale (QoL-AD). Multivariable linear mixed-effects models were used to estimate the association between depression and QOL. RESULTS Results of the multivariable linear mixed-effects models showed a significant association between self-rated QoL-AD and self-rated (B = -0.49, p <0.0001) but not proxy-rated GDS (B = -0.07, p = 0.19) after adjusting for confounders. Likewise, there was a significant association between proxy-rated QoL-AD and proxy-rated GDS (B = -0.48, p <0.0001) but not self-rated GDS (B = 0.05, p = 0.36). CONCLUSION Depression was associated with QOL in AD over short-term longitudinal follow-up, but the association was not statistically significant if both instruments are not administered to the same member of the patient-caregiver dyad. The choice of self- versus proxy-reported QOL should be intentionally considered in future studies as it may influence reported outcomes.

The Effects of Transcranial Direct Current Stimulation in Patients with Mild Cognitive Impairment. Neurol Int 2023; 15:1423-1442. [PMID: 38132971 PMCID: PMC10745513 DOI: 10.3390/neurolint15040092] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Revised: 11/20/2023] [Accepted: 11/21/2023] [Indexed: 12/23/2023] Open
Abstract
Transcranial direct current stimulation (tDCS) came into consideration in recent years as a promising, non-invasive form of neuromodulation for individuals suffering from mild cognitive impairment (MCI). MCI represents a transitional stage between normal cognitive aging and more severe cognitive decline, which appears in neurodegenerative diseases, such as Alzheimer's disease. Numerous studies have shown that tDCS can have several useful effects in patients with MCI. It is believed to enhance cognitive functions, including memory and attention, potentially slowing down the progression of neurodegeneration and cognitive decline. tDCS is believed to work by modulating neuronal activity and promoting synaptic plasticity in the brain regions associated with cognition. Moreover, tDCS is generally considered safe and well-tolerated, making it an attractive option for long-term therapeutic use in MCI. However, further research is needed to determine the optimal stimulation parameters and long-term effects of tDCS in this population, as well as its potential to serve as a complementary therapy alongside other interventions for MCI. In this review, we included 16 randomized clinical trials containing patients with MCI who were treated with tDCS. We aim to provide important evidence for the cognitive enhancement using tDCS in patients with MCI, summarizing the effects and conclusions found in several clinical trials, and discuss its main mechanisms.

Staff-rated ability to provide post-diagnosis support for patients with mild cognitive impairment and related factors. Psychogeriatrics 2023; 23:985-995. [PMID: 37652082 DOI: 10.1111/psyg.13019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/29/2023] [Revised: 07/28/2023] [Accepted: 08/16/2023] [Indexed: 09/02/2023]
Abstract
BACKGROUND Proactive interventions for patients with mild cognitive impairment (MCI) are required. We aimed to determine the staff-rated ability to provide post-diagnosis support for patients with MCI at a medical centre for dementia and the related factors. METHODS We conducted a web-based survey on post-diagnosis support for patients with MCI among healthcare personnel, such as mental health social workers and public health nurses (hereafter referred to as 'staff'), in consultation and support roles at medical centres for dementia nationwide. The latent characteristic value for 'staff's self-rated ability to provide post-diagnosis support to patients with MCI', which was estimated using the one-parameter logistic model of item response theory, was used as the dependent variable. Multivariate linear regression analysis was used to examine the factors associated with the dependent variable. RESULTS We conducted the study at 482 medical centres for dementia. We received responses from 162 participants, 158 of which were valid. We applied item response theory to 45 staff-rated items regarding post-diagnosis support for patients with MCI and found that item difficulty ranged from -2.56 to 1.02; 40 items had negative values and were deemed relatively easy. The staff-rated ability to provide post-diagnosis support was significantly higher for 'The role in assisting patients with MCI is clear' (P < 0.005), 'A reasonable number of personnel is available to assist immediately after MCI diagnosis' (P = 0.001), and 'Collaboration with family physician available immediately after MCI diagnosis' (P < 0.001). CONCLUSIONS The results of this study showed that staff rated their ability to provide post-diagnosis support for patients with MCI as relatively easy. The staff-rated ability to provide post-diagnosis support to patients with MCI may be enhanced by increased availability of staff immediately after MCI diagnosis, clarification of staff roles, and collaboration with family doctors.

Abstract
Mild cognitive impairment (MCI) is a major public health challenge with an increasing prevalence. Although the mechanisms underlying the development of MCI remain unclear, MCI has been reported to be associated with oxidative stress, inflammatory responses, and endothelial dysfunction, suggesting that agents that reduce these factors may be key to preventing MCI. Currently, no agents have been approved for the treatment of MCI, with the efficacy of commonly prescribed cholinesterase inhibitors remaining unclear. Relatively safe natural products that can prevent the development of MCI are of great interest. Linalyl acetate (LA), the major component of clary sage and lavender essential oils, has been shown to have a variety of pharmacological effects, including anti-hypertensive, anti-diabetic, neuroprotective, anti-inflammatory, and antioxidant properties, which may have the potential for the prevention of MCI. The present review briefly summarizes the pathogenesis of MCI related to oxidative stress, inflammatory responses, and endothelial dysfunction as well as the benefits of LA against these MCI-associated factors. The PubMed and Google Scholar databases were used to search the relevant literature. Further clinical research may lead to the development of new strategies for preventing MCI, particularly in high-risk populations with oxidative stress, inflammatory responses, and endothelial dysfunction (e.g., patients with hypertension and/or diabetes mellitus).

Threshold effects of the relationship between physical exercise and cognitive function in the short-sleep elder population. Front Aging Neurosci 2023; 15:1214748. [PMID: 37424629 PMCID: PMC10323428 DOI: 10.3389/fnagi.2023.1214748] [Citation(s) in RCA: 10] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2023] [Accepted: 06/05/2023] [Indexed: 07/11/2023] Open
Abstract
Background It has been demonstrated that elderly people's cognitive capacities can be improved with exercise, and short sleep is linked to cognitive decline. However, the impact of physical exercise on cognitive performance in seniors who do not get enough sleep is largely unknown. This makes it an intriguing subject to explore further. Methods This study consisted of elders (over 60 years old) who participated throughout the National Health and Nutrition Examination Survey's 2011-2014 cycle (NHANES). Weighted linear regression model and restricted cubic splines analysis were performed to evaluate the association between physical exercise and cognitive function. In the end, 1,615 samples were scrutinized and the total number of weighted respondents was 28,607,569. Results Results showed that in the Animal Fluency test and the Digit Symbol Substitution test, a positive association was found between physical exercise volume and scores in the fully adjusted model. A two-piecewise linear regression model was then applied to explore the threshold effect of exercise on cognitive performance. Before 960 and 800 MET-minutes/week, there were consistent positive relationship between exercise and scores of the Animal Fluency test [ß (95% CI): 0.233 (0.154, 0.312), p < 0.001] and Digit Symbol Substitution test [β (95% CI): 0.555 (0.332, 0.778), p < 0.001], respectively. However, there was a saturation effect where physical exercise volume reached the two inflection points. Conclusion According to our research, the benefit of exercise did not always expand with the exercise volume increment under the short-sleep condition, which challenged existing knowledge. The short-sleep elder group could maintain cognitive performance with no more than 800 MET-minutes/week of physical exercise. Verification of these findings requires further biological investigations.

Abstract
BACKGROUND A delay in the detection of mild cognitive impairment (MCI) in the community delays the opportunity for early intervention. Accurate tools to detect MCI in the community are lacking. The Visual Cognitive Assessment Test (VCAT) is a visual based cognitive test useful for multilingual populations without the need for translation. OBJECTIVE Here, we evaluate the usefulness of VCAT in detecting MCI in a community population in Singapore. METHODS We recruited 301 participants from the community who completed a detailed neuropsychological assessment and 170 of them completed a 3T magnetic resonance imaging (MRI) brain scan. We performed a receiver operating characteristics analysis to test the diagnostic performance of VCAT compared to Montreal Cognitive Assessment (MoCA) in distinguishing MCI from cognitively normal (CN) by measuring area under the curve (AUC). To test for the association of VCAT with structural MRI, we performed a Pearson's correlation analysis for VCAT and MRI variables. RESULTS We recruited 39 CN and 262 MCI participants from Dementia Research Centre (Singapore). Mean age of the cohort was 63.64, SD = 9.38, mean education years was 13.59, SD = 3.70 and majority were women (55.8%). VCAT was effective in detecting MCI from CN with an AUC of 0.794 (95% CI 0.723-0.865) which was slightly higher than MoCA 0.699 (95% CI 0.621-0.777). Among subjects with MCI, VCAT was associated with medial temporal lobe atrophy (ρ = -0.265, p = 0.001). CONCLUSIONS The VCAT is useful in detecting MCI in the community in Singapore and may be an effective measure of neurodegeneration.

Abstract
Caregiving can be physically challenging and emotionally draining for older caregivers. The existing research on physical and emotional strain mainly focuses on the general caregiver population. Using the Stress Process Model, this study aims to expand on existing caregiving literature by identifying correlates of physical and emotional strain among older caregivers. Hierarchical OLS regressions were performed on data selected from the 2015 Caregiving in the U.S. Survey (N = 701). Several risk factors for physical strain and emotional strain were identified: Assistance with ADLs and IADLs, the number of health problems of the care recipient, and the receipt of formal support were positively associated with physical and emotional strain. Moreover, providing care to parents/parents-in-law was associated with higher levels of emotional strain than providing care to non-relatives. The number of care recipients was positively associated with emotional strain. Older African Americans experienced lower levels of physical strain than their white counterparts. The findings uncover the individual differences among older caregivers and provide insights into how these differences uniquely influence caregiving strain. Moreover, the study identifies a risk and protective profile of caregiving strain, which can help practitioners direct services and resources to older caregivers who are particularly at risk for caregiving strain.

Abstract
BACKGROUND Little is known regarding the effects of training programs on family caregivers of older persons with mild cognitive impairment because of the significant differences in outcome variables measured in the various studies in the literature. PURPOSE This study was designed to examine the effects of an outpatient-based caregiver training program on the preparedness, health-related quality of life, and depressive symptoms of participants responsible for caring for older persons with mild cognitive impairment. METHODS A randomized clinical trial was implemented. Of the 54 family caregiver participants who provided complete and valid data, 28 and 26 were assigned to the experimental and control groups, respectively. The experimental group participated in a researcher-developed training program that provided information on mild cognitive impairment, strategies for maintaining and promoting cognitive function in persons with mild cognitive impairment, managing their own and their care recipients' healthcare, and managing their own emotional support and stress. Outcomes (caregiver preparedness, health-related quality of life, and depressive symptoms) were assessed before the start of the training program (baseline) and at 1, 3, and 6 months after completion of the program. RESULTS After controlling for baseline cognitive function of the care recipients and of caregiver preparedness, the experimental group was shown to be significantly less prepared than the control group at baseline (β = -1.41, p = .031) and better prepared than the control group at all three posttests (group differences: 1.3, 1.53, and 4.24, respectively), with the difference at the third posttest (6 months) reaching statistical significance (p = .008). No impact of the intervention on caregiver depressive symptoms or health-related quality of life was found at posttest. CONCLUSIONS The training intervention in this study was found to increase the perceived preparedness of the family caregiver participants to handle various aspects of providing care to persons with mild cognitive impairment. However, no changes were found in depressive symptoms or health-related quality of life.

Abstract
Introduction Caused by an error in cell division that produces an additional chromosome 21, Down syndrome (DS) is one of the most common developmental disorders in the world. This study aims to analyze the relationship between psychological capital, quality of life and well-being of caregivers of individuals with Down syndrome (DS). Methods The participants were 98 caregivers (mothers, M = 52.13, SD = 11.39) of individuals with Down syndrome. The instruments used were the Psychological Capital Questionnaire (measuring self-efficacy, resilience, optimism, and hope), Quality of Life Questionnaire (including social support, general satisfaction, physical/psychological health, absence of excessive workload/free time), and Psychological Wellbeing Scale, investigating the following dimensions: self-acceptance, positive relationships with others, autonomy, environmental mastery, purpose in life, and personal growth. Results The mediation analysis showed that self-efficacy, hope, and resilience are positively associated to quality of life, and optimism is positively associated to well-being. The total effects of psychological capital on well-being are positive and significant and quality of life mediates the relationship between psychological capital and well-being. Discussion These results show that psychological capital is an important inner resource for caregivers of DS individuals and must be improved through support services, so that caregivers have a higher perception of the quality of life and implicitly of well-being.

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.

Abstract
Mild cognitive impairment (MCI) is often accompanied by executive dysfunction (ED), dysexecutive behaviors (DB), and functional impairment (FI). The respective contributions of ED, DB, and FI to caregiver burden in MCI are not well understood. The present study hypothesized that while all factors would predict caregiver burden in MCI, ED and family-reported DB would account for greater variance in caregiver burden and mediate the relationship between FI and caregiver burden. In our sample (n = 94), linear regression revealed that FI and DB predicted caregiver burden, but that DB predicted caregiver burden above and beyond the contribution of FI. DB mediated the relationship between FI and caregiver burden. These results add to a body of work demonstrating that presence of DB and FI are distressing to family members, even in mild disease stages. Because DB may account for the relationship between FI and caregiver burden, early identification of family members reporting DB in the person with MCI is imperative so that supports can be made available.

Abstract
Background Intermediate care is often defined as healthcare occurring somewhere between traditional primary (community) and secondary (hospital) care settings. High quality intermediate care is important in dementia, may prevent caregiver burnout and also lead to optimal care for people with dementia. However, very little is known about the point of intermediate care for persons with dementia in Europe. Research questions What intermediate care services exist and how are they utilized in the care of people with dementia in Europe? Objective This study aims at describing the point of view of General Practitioners on intermediate care services for people with dementia across Europe. Methods Key informant survey was sent to GPs via a self-developed questionnaire with space for open ended comments. 16 European countries participated to this cross-sectional mixed method study. Given the volunteer nature of the study, no minimum sample size requirements were applied to participation. Convenience sampling technique was used to address variations due to regional variations and regulations within the same country. Descriptive analyses of all intermediate care facilities groups by countries were performed. Qualitative analyses approach was used for the optional-free text to exemplify and/or complete the reasons contained in the closed response categories. Results The questionnaire was sent to 16 European countries. 583 questionnaires were analyzed. The responding physicians were 48 (± 11) years old on average and they had been in practice for an average of 18 (+ /11) years. The types of intermediate care considered were integrated at-home services, respite and relief services, day care centers and nursing homes. Their availability was considered very inhomogeneous by the majority of respondents. The main benefits of intermediate care cited were better medical care for the patient (78%), better quality of life for the caregiver (67%), prevention of the caregiver burden (73%) and a break for the caregiver (59%). The reported difficulties were: accessing these facilities due to limited financial support (76%) and cumbersome administrative procedures (67%). Many other facets of our findings were captured in the qualitative themes that emerged. Conclusion Intermediate care in Europe is diverse and heterogeneous. Major concerns of GPs are about the cost issues and the cumbersome administrative procedures to access them.

A 'good dyadic relationship' between older couples with one having mild cognitive impairment: a Q-methodology. BMC Geriatr 2022; 22:764. [PMID: 36131229 PMCID: PMC9494827 DOI: 10.1186/s12877-022-03449-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2022] [Accepted: 09/14/2022] [Indexed: 11/17/2022] Open
Abstract
BACKGROUND Cognitive impairment gradually brings changes to the relationship between older married couples. Therefore, this study aimed to understand the individual viewpoints of couple dyads on the important attributes of a 'good dyadic relationship' in the context of mild cognitive impairment (MCI), and to explore if the congruencies and discrepancies in their perceptions related to the quality and closeness of their relationship and well-being. METHODS Q-methodology was used to reveal the perceptions of a 'good dyadic relationship' among couples with one having MCI. The participating couples were separated in two rooms and independently ranked 18 relationship attributes from least to most important on a 7-point Q-sort response grid. All participants also completed a post-sort interview and surveys to assess their psychological well-being and closeness. Q-sorts were analyzed using by-person factor analysis. RESULTS Forty people with MCI and forty spousal partners completed the Q-sort. Three viewpoints, accounting for 48% of the total variance, were identified and were labeled 'Provider,' 'Problem-solver,' and 'Partner.' Different viewpoints of a 'good dyadic relationship' primarily varied by perceived importance of commitment, dedication, tolerance, and personal space. Despite these differences, there was wide consensus that respecting each other and cherishing the current moment are two universally salient attributes of a good relationship across all viewpoints. Couples with discrepant views scored significantly higher on perceptions of the quality of the relationship and closeness with the partner. CONCLUSIONS This study advances the theoretical understanding of the dyadic relationship between couples with one having MCI, from both perspectives. MCI is a state in which couples can openly discuss their expectations. The findings provide practitioners with insights to work with couples experiencing MCI.

Psychometric Properties and Measurement Invariance of the Chinese Version of the Brief Assessment of Impaired Cognition Questionnaire in Community-Dwelling Older Adults. Front Public Health 2022; 10:908827. [PMID: 35784243 PMCID: PMC9247353 DOI: 10.3389/fpubh.2022.908827] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2022] [Accepted: 05/17/2022] [Indexed: 11/29/2022] Open
Abstract
This study aimed to verify the Chinese version of the Brief Assessment of Impaired Cognition Questionnaire (C-BASIC-Q), and provide a new tool for the future large-scale epidemiological investigation of cognitive function in China. From March to May 2021, a cross-sectional study of 2,144 Chinese community-dwelling older adults (men = 1,075, mean age = 72.01 years, SD = 6.96 years, ranging from 60–99 years) was conducted in Jinan. Exploratory and confirmatory factor analyses were performed to evaluate the factor structure of the C-BASIC-Q. Convergent validity was evaluated by correlations with the Mini-Mental State Examination (MMSE). Internal consistency and test-retest reliability were evaluated using Cronbach's alpha and retest correlations in a sub-sample (n = 129). Linear regression was used to analyze the impact of demographic factors on the MMSE and C-BASIC-Q scores. Measurement invariance was evaluated using a multi-group confirmatory factor analysis. The mean C-BASIC-Q score was 15.94 (SD = 3.43). Factor analysis suggested a three-factor structure of C-BASIC-Q (self-report, orientation, and informant report). The C-BASIC-Q score was significantly positively associated with the MMSE score, showing good convergent validity. Cronbach's alpha of the C-BASIC-Q was 0.862, and the test-retest correlation coefficient was significant (r = 0.952, p < 0.001), indicating good internal consistency and test-retest reliability. Measurement invariance analysis showed that C-BASIC-Q had configural, metric, and scalar invariance across sex, age, residence, education level and marital status. C-BASIC-Q was less affected by age, residence, education, and marital status than the MMSE. In summary, the C-BASIC-Q had good reliability, validity, and measurement invariance, and is a valid tool for evaluating cognitive functioning in Chinese community-dwelling older adults.

Patient-Related Factors Influencing Caregiver Burden in Parkinson’s Disease Patients: Comparison of Effects Before and After Deep Brain Stimulation. JOURNAL OF PARKINSON'S DISEASE 2022; 12:1285-1293. [PMID: 35275557 PMCID: PMC9484085 DOI: 10.3233/jpd-213093] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Indexed: 12/02/2022]
Abstract
Background: Caregivers of Parkinson’s disease (PD) patients provide important support during the pre- and postoperative phase of deep brain stimulation (DBS). High levels of caregiver burden have been reported after DBS. However, a comparison between preoperative and postoperative burden and associated factors has been insufficiently studied. Objective: To investigate the influence of DBS on caregiver burden, and to identify the differential impact of patient-related factors on caregiver burden before and after DBS. Methods: Consecutive patients referred for DBS eligibility screening or during one-year follow-up assessments were included. Caregiver burden was measured with the short Zarit Burden Interview (ZBI-12). Inverse Probability Weighting (IPW) was used to compare caregiver burden between preoperative and postoperative assessments. Results: We included 47 patients (24 screening, 23 follow-up) (median age 65 years, 29.4% female sex). DBS did not impact caregiver burden (screening: median ZBI-12 9.5 (IQR 3.25, 16.75); follow-up median ZBI-12 6 (IQR 4, 14); IPW-coefficient 0.57 (95% CI –2.75, 3.89)). Worse caregiver burden during DBS screening was associated with worse patient-related scores on depressive symptoms, anxiety, QoL, and impulsiveness. Worse scores on depressive symptoms, anxiety, apathy, postural-instability-gait-disorder, and QoL were associated with worse caregiver burden at one-year follow-up. Conclusion: DBS appears not associated with changes in caregiver burden. Various symptoms are valued differently between screening and follow-up assessments in terms of caregiver burden. Early recognition of caregivers “at risk” may improve guidance of patient-caregiver dyads throughout the DBS process.

Independent associations between sleep duration, gamma gap, and cognitive function among older adults: Results from the NHANES 2013-2014. Geriatr Nurs 2022; 44:1-7. [PMID: 34998076 DOI: 10.1016/j.gerinurse.2021.12.019] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2021] [Revised: 12/21/2021] [Accepted: 12/23/2021] [Indexed: 12/20/2022]
Abstract
This study examined whether gamma gap mediated the association between sleep and cognitive function. Data from NHANES 2013-2014 were used. Three tests were used to measure cognitive function. Sleep was measured by three single questions. Gamma gap was calculated by subtracting albumin from total protein. Participants were 1392 older adults (53.2% females). Approximately 12% reported being told having sleep disorder, 1/3 reported having trouble sleeping, 25.9% had short sleep, and 12.5% had long sleep. Sleep disorders and sleep quality were not associated with cognitive function. Long sleep duration was an independent risk factor of reduced cognitive function on immediate recall, delayed recall, and executive function. Elevated gamma gap was also an independent risk factor of lower cognitive function. In a representative sample of older adults in the US, gamma gap and sleep duration were independent predictors of cognitive function. This study highlights the need for sleep assessment among older adults.

Abstract
With the aging population, dementia emerges as a public health concern. In 2012, the Health and Retirement Study found that 8.8% of adults over 65 years suffered from dementia. The etiopathogenesis and treatment of dementia are not well understood. Antioxidant properties of Vitamin E and its major elements tocopherols and tocotrienols have been reported to be effective in slowing down the progression of dementia from its initial stage of Mild cognitive impairment (MCI). Therefore, the current review aims to explore the role of vitamin E on MCI. A literature search using the key words "Vitamin E, tocopherols, tocotrienols, and mild cognitive impairment" was conducted in MEDLINE (PubMed), CINAHL, and Google Scholar. The inclusion criteria were: (1) articles published in the past ten years; (2) published in English language; (3) published in peer-reviewed journals; and (4) descriptive and epidemiological or evaluation studies. Articles published prior to 2010, focused on other forms of dementia than MCI, grey literature and non-peer-reviewed articles were excluded. A total of 22 studies were included in the narrative synthesis. The results were equivocal. Eleven studies showed some level of the neuroprotective effect of Vitamin E, tocopherols and tocotrienols on the progression of MCI. The mixed results of this review suggest further exploration of the possible protective effects of Vitamin E on the development of dementia. Future studies can be conducted to decipher antioxidant properties of vitamin E and its association with slowing down the cognitive decline.

Abstract
BACKGROUND Previous studies on the relationship between cognitive impairment and adverse outcomes among geriatric inpatients are not representative of older inpatients in China because of insufficient sample sizes or single-center study designs. The purpose of our study was to examine the prevalence of cognitive impairment and the relationship between cognitive impairment and 1-year adverse health outcomes in older inpatients. METHODS This study was a large-scale multi-center cohort study conducted from October 2018 to February 2020. Six tertiary hospitals across China were selected using a two-stage cluster sampling method, and eligible older inpatients were selected for the baseline survey and follow-up. The Mini Cognitive Scale and the FRAIL scale were used to screen for cognitive impairment and frailty, respectively. The EuroQol-5 Dimension-5 Level questionnaire was used to assess health-related quality of life (HRQoL). We used a generalized estimating model to evaluate the relationship between cognitive impairment and adverse outcomes. RESULTS The study included 5008 men (58.02%) and 3623 women (41.98%), and 70.64% were aged 65-75 years, and 26.27% were aged 75-85 years. Cognitive impairment was observed in 1756 patients (20.35%). There were significant differences between participants with cognitive impairment and those with normal cognitive function for age, gender, surgery status, frailty, depression, handgrip strength and so on. After adjusting for multiple covariates, compared with patients with normal cognitive function, the odds ratio for 1-year mortality was 1.216 (95% confidence interval [CI]: 1.076-1.375) and for 1-year incidence of frailty was 1.195 (95% CI: 1.037-1.376) in patients with cognitive impairment. Similarly, the regression coefficient of 1-year HRQoL was - 0.013 (95% CI: - 0.024-- 0.002). In the stratified analysis, risk of adverse outcome within 1 year was higher in older patients with cognitive impairment aged over 75 years than those aged 65-74 years. CONCLUSIONS We revealed that cognitive impairment was highly correlated with occurrence of 1-year adverse health outcomes (death, frailty, and decreased HRQoL) in older inpatients, which provides a basis for formulating effective intervention measures.

Abstract
BACKGROUND Although caregiver burden is common among carers of people with dementia, little is known about its prevalence and predictors among caregivers of patients attending memory clinics. OBJECTIVE To examine carer and patient-specific characteristics associated with caregiver burden across the cognitive spectrum in a memory clinic population. METHODS Consecutive patients referred to a university hospital geriatric memory clinic were included. Caregiver burden was scored using the Caregiver Burden Score (CBS), (modified Zarit), with scores≥15/30 suggesting burden. BPSD were measured with the dysfunctional behaviour rating instrument (DBRI). Cognition was screened using the Montreal Cognitive Assessment (MoCA) and Quick Mild Cognitive Impairment (Qmci) screen. RESULTS In all, 351 patients were included, median age 77 (±11) years; 65.5% were female. The prevalence of caregiver burden was 33.6% overall, increasing from 10.8% in subjective cognitive decline (SCD), to 15% in mild cognitive impairment (MCI) and 43% in dementia; CBS scores were significantly higher in dementia (p < 0.001). Caregivers with burden were significantly younger (p = 0.045) and were more likely to be adult children (p = 0.007). The CBS weakly correlated with the stage of cognitive impairment (r = 0.16) but had moderate correlation with MoCA (r = -0.54) and Qmci scores (r = -0.60). After adjustment for co-variates, DBRI scores alone independently predicted burden (odds ratio 1.23;1.11-1.35, p < 0.001). CONCLUSION Caregiver burden is associated with the stage of cognitive impairment, with higher prevalence proportions in those with dementia compared with MCI and SCD. Only the severity of neuropsychiatric symptoms independently predicted caregiver burden in this population and its presence should prompt assessment for burden.

Abstract
OBJECTIVE Despite the policy relevance of carer burden, limited research focuses on family carers' experience of carer burden among different disease groups. This study aimed to examine differences in carer burden among family carers of people with and without dementia. DESIGN Secondary data analysis was conducted on a national cross-sectional dataset. Multivariable ordered logistic regression was used to analyze four levels of carer burden (low, mild, moderate, high). The main independent variable was dementia diagnosis, and controls included variables relating to the care recipient, family carer, and context of care. SETTING The original survey was funded by Irish Health Service Executive and undertaken by the National Centre for the Protection of Older People in Ireland. PARTICIPANTS The original dataset consisted of 2,311 family carers of older people in Ireland. Approximately, one-fifth of this sample had a diagnosis of dementia. MEASUREMENTS Carer burden was measured using the standardized 22-item Zarit Burden Interview. Care-recipient dependency was measured using the Activities for Daily Living Scale. Sociodemographic details and information about the context of caring were collected using self-report scales. RESULTS In our model, dementia diagnosis and dependency level were significantly associated with carer burden. Family carer and context of care variables including gender, marital status, education, residence, co-residence, and perceived support showed significant relationships with carer burden. Our results highlighted significant differences in carer burden distribution; in particular, family carers of people with dementia were less likely to report low or mild carer burden (-6.95 ppts and -3.64 ppts, respectively) and more likely to report moderate or high carer burden (8.46 ppts and 2.13 ppts, respectively). CONCLUSION Our findings suggest that family carers of people with dementia may experience additional challenges associated with caring. Therefore, family carers of people with dementia may require tailored social supports to maintain good health and well-being.

Abstract
AIMS AND OBJECTIVES This study examined the predictors of caregiver burden based on patient and caregiver characteristics in a sample of Spanish caregivers looking after adult patients with chronic disease. The effect of task type and patient-caregiver interaction is also analysed. BACKGROUND Specific predictors of caregiver burden have been widely examined in the literature. Few studies, however, jointly analyse a wide range of factors, including the effect of task type and patient-caregiver interaction. DESIGN Correlational study. METHODS One hundred and thirty five informal caregivers for 148 care recipients were recruited from primary health care centres. The caregivers responded to the short version of the Zarit Burden Interview (ZBI), the DEPendency index-6 Dimensions (DEP-6D), and reported how long they spent on caregiving on a daily basis. Sociodemographic and health characteristics were also recorded. Linear and logistic regression models were used to evaluate factors associated with ZBI scores and the likelihood of being severely burdened, respectively. This research complies with STROBE guidelines for observational studies. RESULTS Severe burden was present in 62% of the caregivers. Regression analysis shows that burden severity increases significantly with the level of dependence when the latter is measured either by DEP-6D or by time spent on basic activities. Care related to incontinence and mobility has the greatest effect on burden, which is aggravated when the patient has behavioural problems. Poor caregiver health or not being retired also contributes to burden levels. CONCLUSIONS These results establish that caregiver burden is related to characteristics of both the caregiver and the care recipient as well as to their interaction. RELEVANCE TO CLINICAL PRACTICE The findings indicate that the socio-sanitary attention focused on reducing caregiver burden must address the caregiver and patient as a dyad. Identifying the dependence level and the patient's aggressive behaviour can be a good predictor of caregiver burden.

Abstract
Background: Alzheimer’s disease (AD) is one of the costliest diseases in the United States. Objective: To describe aspects of real-world patient and caregiver burden in patients with clinician-diagnosed early AD, including mild cognitive impairment (MCI) and mild dementia (MILD) due to AD. Methods: Cross-sectional assessment of GERAS-US, a 36-month cohort study of patients seeking care for early AD. Eligible patients were categorized based on study-defined categories of MCI and MILD and by amyloid positivity [+] or negativity [–] within each severity cohort. Demographic characteristics, health-related outcomes, medical history, and caregiver burden by amyloid status are described. Results: Of 1,198 patients with clinician-diagnosed early AD, 52% were amyloid[+]. For patients in both cohorts, amyloid[–] was more likely to occur in those with: delayed time to an AD-related diagnosis, higher rates of depression, poorer Bath Assessment of Subjective Quality of Life in Dementia scores, and Hispanic/Latino ethnicity (all p < 0.05). MILD[–] patients (versus MILD[+]) were more medically complex with greater rates of depression (55.7% versus 40.4%), sleep disorders (34.3% versus 26.5%), and obstructive pulmonary disease (11.8% versus 6.6%); and higher caregiver burden (Zarit Burden Interview) (all p < 0.05). MILD[+] patients had lower function according to the Functional Activities Questionnaire (p < 0.001), yet self-assessment of cognitive complaints across multiple measures did not differ by amyloid status in either severity cohort. Conclusions: Considerable patient and caregiver burden was observed in patients seeking care for memory concerns. Different patterns emerged when both disease severity and amyloid status were evaluated underscoring the need for further diagnostic assessment and care for patients.

Abstract
By 2025, 34 million people worldwide will be living with Alzheimer's disease or another form of dementia (i.e., neurocognitive disorders). Symptoms of neurocognitive disorders have functional repercussions on daily activities. People with neurocognitive disorders often rely on a caregiver to alleviate the impact of their symptoms, but this help has consequences for the caregiver. Indeed, caregivers report subjective burden, depressive symptoms, stress, anxiety and a lower quality of life than non-caregivers. Multiple cognitive-behavioral therapy (CBT) trials have been conducted to reduce these symptoms for caregivers. No meta-analysis has been conducted to evaluate the efficacy of this type of intervention on reducing subjective burden. Articles were selected from PsycNet, MEDLINE, AgeLine and ProQuest Dissertation and Theses for the period from 2000 to 2017. Article selection, data extraction and bias analysis for individual studies were completed by two independent authors who used a consensus procedure when discrepancies occurred. A total of 20 articles were included in the systematic review. Ten studies evaluated the efficacy of CBT in reducing subjective burden, and the meta-analysis suggested a significant reduction in subjective burden following CBT. Additionally, 17 studies evaluated the efficacy in reducing depressive symptoms, and the meta-analysis revealed a significant reduction for these caregivers following CBT. CBT for caregivers of individuals with a neurocognitive disorder had no impact on stress, anxiety, or quality of life.

Abstract
Family members-mainly spouses and partners-are the primary caregivers for individuals with Alzheimer's disease and related dementias (ADRDs), chronic progressive illnesses requiring increasing levels of care. We performed a retrospective observational analysis comparing depressive symptoms of 16,650 older individuals with partners without ADRDs, and those recently (within 2 years) or less recently diagnosed (≥2 years prior), controlling for lagged sociodemographic and health characteristics. The mean number of reported depressive symptoms was 1.2 (SD = 1.8). Compared with respondents with partners with no ADRD, having a partner with any ADRD was associated with a 0.35 increase (95% confidence interval [CI] = [0.30, 0.41]), or 30% increase, in depressive symptoms. A less recent partner diagnosis was associated with a 33% increase, while a recent diagnosis was associated with a 27% increase. Clinically meaningful and longitudinally worsening depressive symptoms amplify the need to prioritize partner health and family-centered care following an ADRD diagnosis.

Abstract
This paper aims to understand the experiences of family caregivers with dependent older adults in Brazil and the consequences of caring for dependent older adults in the family caregiver's life. This is a qualitative multicenter study employing dialectical hermeneutics as a theoretical framework. In-depth interviews were conducted with 84 family caregivers in Brasília, Rio de Janeiro, Belo Horizonte, Fortaleza, Teresina, Porto Alegre, and Araranguá, and Manaus. The thematic analysis yielded three categories: motivations for taking on the caregiving role, influences on the family caregiver's life, coping, and self-care modalities. The care assumed is influenced by affective relationships with older adults and ethical and moral responsibilities. The influences are related to the lack of preparation for caregiving, financial hardship, restricted freedom, and physical and mental health problems. Coping strategies were religion, spirituality, turn-taking between family caregivers, and learning about the tasks. Women predominate in caregiving due to cultural, ethical, and moral reasons. However, family caregivers often lack guidance and require protection and a support network.

Abstract
OBJECTIVES Dementia, with its progressive cognitive and functional decline and associated neuropsychiatric symptoms, places a large burden on caregivers. While frequently studied, longitudinal findings about the overall trajectory of burden are mixed. The study sought to characterize caregiver burden over a 3-year period and identify predictors of this burden. METHODS Seven-hundred-and-eighty-one patients with dementia were recruited from nine memory clinics around Australia. Measures of caregiver burden, cognition, function, and neuropsychiatric symptoms were completed with patients and their caregivers at regular intervals over a 3-year period. Patients' level of services and medication use were also recorded. RESULTS Of the 720 patients with measures of caregiver burden at baseline, 47.4% of caregivers had clinically significant levels of burden. This proportion increased over time, with 56.8% affected at 3 years. Overall levels of burden increased for caregivers of patients without services, though did not change for caregivers of patients receiving services or residential care after controlling for other variables. Patient characteristics-including greater neuropsychiatric symptoms, lower functional ability, fewer medications, lack of driving ability-and female sex of caregivers were associated with greater burden. CONCLUSIONS High levels of caregiver burden are present in a large proportion of caregivers of people with dementia and this increases over time for those without services. Clinical characteristics of patients (including neuropsychiatric symptoms, function, overall health, driving status), level of services, and caregiver sex appear to be the best predictors of this burden. These characteristics may help identify caregivers at greater risk of burden to target for intervention.
