Subjective memory complaints and difficulty performing activities of daily living among older women in Australia

Subjective Aging and Basic Activities of Daily Living: Moderation by Health Care Access and Mediation by Health Care Resources

Subjective aging in older adults is associated with a decline in basic activities of daily living (bADL), although this is less well studied with increasing age cohorts by their healthcare resources (HCR) and healthcare access (HCA) controlling for sociodemographics. We aimed to address this gap in knowledge by analyzing the National Health and Aging Trends round 11 data set on 3303 older adults aged 70 to above 90, comprising 42% male and 58% female by age cohort (middle-old -70-79, n = 1409; older-old -80-89, n = 1432, oldest-old- 90 plus, n = 462). Results of mediation-moderation analysis show the subjective aging whole model comprising subjective cognitive decline, HCR, HCA, and sociodemographic to predict a decline in bADL with increasing age to be higher among the older-old age (80-89) compared to the middle-old age (70-79) or oldest-old (90 years +) cohorts. These findings suggest a "doughnut" effect by which the older-old age cohort of 80-89 may be coping less well with their bADL, while the oldest-old may have adapted to functional loss in their everyday living and/or comprises adults who may have passed a mortality selection despite a more significant burden of comorbidity.

Association of mobile device proficiency and subjective cognitive complaints with financial management ability among community-dwelling older adults: a population-based cross-sectional study

BACKGROUND

Mobile devices have been used by many older adults and have the potential to assist individuals with subjective cognitive complaints (SCCs) in daily living tasks. Financial management is one of the most complex daily activity for older adults, as it is easily impaired in the prodromal stage of dementia and cognitive impairment.

AIM

To investigate financial management ability among older adults from SCCs and mobile device proficiency.

METHODS

A self-administered questionnaire was sent to 529 participants who were ≥ 65 years and regularly use mobile devices. Participants were divided into four groups based on SCC prevalence and scores of the Mobile Device Proficiency Questionnaire (MDPQ-16). Financial management abilities were compared between groups using the Process Analysis of Daily Activities for Dementia subscale. Regression model and crosstabulation table were used to investigate associations in detail.

RESULTS

A significant difference in financial management ability was observed among the four groups (p < 0.001), with the dual impairment group showed significantly lower than the robust and SCC groups (p < 0.001). Educational history, sex, and MDPQ-16 score were significantly associated with participants' financial management ability (p ≤ 0.01). The proportion of participants who could use ATMs and electronic money independently was significantly lower among those with low proficiency in mobile devices (LPM), regardless of SCC (p < 0.05).

CONCLUSION

The LPM group showed an impaired ability to manage their finances, particularly in situations where they would use information devices. Therefore, healthcare professionals should assess not only the SCC but also their proficiency with mobile devices to predict their impairment in activities of daily living.

Lifestyle and behavioural changes in older adults during the Covid-19 pandemic are associated with subjective cognitive complaints

Subjective cognitive complaints (SCC) is a self-reported experience of persistently impaired cognitive functions which could be the earliest red flag of neurocognitive disorders. The COVID-19 pandemic and related restriction measures changed the lifestyle and behaviour of older adults. The aim of this study was to assess the relation of these changes and SCC status in Hungary. This cross-sectional study analysed the data of 359 elderly Hungarians who filled out the WW-FINGERS-SARS-CoV2 survey. A quarter of the respondents (n:88) reported SCC in connection with the pandemic. We compared sociodemographic features, health status, lifestyle, and social life parameters between subjects with reported SCC and without. To eliminate the potential interrelation across group differences, stepwise logistic regression was applied. Participants with SCC showed the following characteristics, compared to individuals without: (1) they were older; (2) they were more likely to be women; (3) they had a higher number of chronic disorders; (4) showed more prominent impairment in physical mobility; (5) had worse sleep quality; (6) spent less time with family; and (7) used internet more frequently during the pandemic (all p's < 0.001). Logistic regression highlighted that only two parameters were related to SCC status independently, the physical mobility (ability to walk 500 m without difficulties; OR = 1.186; p < 0.001; 95%CI = 1.101, 1.270) and changes in time spent with grandchildren (OR = 1.04; p = 0.015; 95%CI = 1.008, 1.073). Our study draws attention to the importance of physical mobility and quality time with family as key factors in the cognitive well-being of elderly people.

Association Between Neuropsychological Functions and Activities of Daily Living in People with Mild Cognitive Impairment

OBJECTIVE

The aim of this study was to explore the relationship between performance in neurocognitive variables and daily functioning (basic or b- and instrumental or i-ADL) in people with mild cognitive impairment (MCI).

METHODS

A sample of 157 participants with MCI (73.65 ± 7.58 years) completed a battery of tests for assessing ADL and cognitive functions. t-test, Pearson's correlation and multiple linear regression (backward stepwise selection) were used for data analyses.

RESULTS

Significant correlations were found between b- and i-ADL, and several neuropsychological tests (p < .01). Multivariate analysis showed that difficulties in Blessed Rating Scales (BLS) explained 33.2% of the variation in b-ADL and that this variation rises to 42.9% when BLS is associated with Frontal Assessment Battery Flexibility, Trail Making Test A (TMT-A) and BLS Personality. For i-ADL, BLS and Dementia Rating Scale Total (DRS-T) explained 47.7% of the variation and the inclusion in the model of BLS, DRS-IP (Initiation/Perseveration), TMT-A and BLS Personality explained 53.5% of this variation. Executive functions explained 24.8% of the variation in i-ADL.

CONCLUSIONS

Cognitive functions are related to i- and b-ADL in people with MCI. The general indicators and those that assess executive functions and verbal- or visual-spatial memory should be considered to predict i-ADL.

Subjective Memory Complaints Predict Decline in Memory, Instrumental Activities of Daily Living, and Social Participation in Older Adults: A Fixed-Effects Model

IMPORTANCE

Although subjective memory complaints (SMCs) have been suggested to be associated with future memory impairment, limitations in instrumental activities of daily living (IADLs), and social participation restriction, these associations are still inconclusive.

OBJECTIVE

To determine whether changes in SMCs over time predict decline in memory, IADLs, and social participation in older adults.

DESIGN

Longitudinal study.

SETTING

Community.

PARTICIPANTS

Sample 1 included 2,493 community-dwelling older adults drawn from the Health and Retirement Study (HRS) data collected between 2004 and 2018. Sample 2 included 1,644 community-dwelling older adults drawn from the HRS data collected between 2008 and 2018.

OUTCOMES AND MEASURES

Self-reported SMCs, memory function, self-reported IADL performance, and self-reported social participation.

RESULTS

The mean age of Sample 1 at baseline was 70.16 yr; 1,468 (58.88%) were female. In Sample 1, immediate and delayed memory (all ps < .001) and IADL performance (p < .01) declined over time. Increases in SMCs over time significantly predicted future immediate and delayed memory declines (p < .01 and p < .001, respectively) and future IADL performance decline (p < .001), after controlling for depressive symptoms. The mean age of Sample 2 at baseline was 71.52 yr; 928 (56.45%) were female. In Sample 2, social participation declined over time (all ps < .001). Increases in SMCs over time significantly predicted future social participation decline (p < .05), after controlling for depressive symptoms.

CONCLUSIONS AND RELEVANCE

Increases in SMCs predict future decline in memory, IADL performance, and social participation after accounting for depressive symptoms. What This Article Adds: SMCs can be used as an early indicator of future memory impairment, IADL limitations, and social participation restrictions in older adults. Furthermore, interventions that minimize SMCs may help older adults achieve successful aging.

Sex differences on anxiety and depression in older adults and their relationship with cognitive impairment

INTRODUCTION

Subjective memory complaints (SMCs) in elderly adults could express cognitive decline in the future. A consensus has been reached about how these SMC relate to mood variables, but further research is required to determine which socio-demographic, cognitive, functional and occupational factors will act as predictors in elderly adults.

OBJETIVE

To analyze, through a descriptive observational study, the relationship between anxiety/depression and sex, age and occupation, with cognitive/functional performance in 367 older adults with SMC, but without objective cognitive impairment in a primary healthcare center.

METHODS

The cognitive variables were measured by applying the Spanish version of Mini-Mental State Examination (MEC-35) and Set-test for verbal fluency. To measure functional level, the Barthel index and Lawton and Brody scales were employed. Physical occupational status and mental occupational status were measured based on three levels, low, medium and high, according to the American Occupational Therapy Association.

RESULTS

Low educational and occupational physical and mental levels were related to anxiety and depression. In addition, differences by sex were found on anxiety and depression related to different factors. In men, anxiety was related to higher cognitive level, and in women to higher functional performance in IADLs. On the contrary, depression in men was related to lower cognitive level and higher performance in ADLs.

CONCLUSIONS

It is important to maintain a sex-gender perspective on the study of anxiety and depression in elderly, taking into account social roles and the traints of the work environment, in order to avoid cognitive and functional impairment.

The association between low cognitive reserve and subjective memory complaints in functionally independent older women

BACKGROUND

Several factors have been found to defend against pathologic cognitive decline in aging (i.e., cognitive reserve [CR]); however, other factors, including subjective memory complaints (SMC) and decreased functionality are considered early indicators of underlying neurocognitive dysfunction. Despite these known associations, the relationship between the presence of CR and SMC remains equivocal. This study sought to determine the relationship between objectively measured CR and SMC in a sample of functionally independent older women.

METHODS

This cross-sectional study recruited women aged ≥60 years who attended fitness or continuing education programs at the University for Seniors in Mexico City. Participants underwent a battery of physical and cognitive evaluations, including the Cognitive Reserve Questionnaire (CRQ), and were asked probing questions used to identify the presence of SMC.

RESULTS

The 269 participants had a median age of 69 years; most were single (40.5 %), lived alone (32.7 %), retired (58.2 %), well-educated (≥12 years of education), and functionally independent (89.2 %). 62 % scored "high" on the CRQ, while 9.3 % scored "low". After adjusting for multiple covariates, an independent association between CRQ score and the probability to have SMC was found (adjusted OR = 0.87, 95% CI 0.80-0.95, p-value = 0.002).

CONCLUSIONS

This study identified a relationship between low CR and the presence of SMC, independently of the cognitive function and motoric marker of muscle strength (i.e., low gait speed and handgrip strength) in functionally independent older women over 60y. This relationship remains independent of other variables such as age, symptoms of depression and instrumented activities of daily living.

Prevalence and Factors Associated with Subjective Memory Complaint in a Semi-Rural Community in Chile

BACKGROUND

Subjective memory complaints (SMC) are commonly studied in older adults and have been identified as potentially prodromal to dementia and Alzheimer's disease. Studies among younger adults from South America are lacking.

OBJECTIVE

To estimate the prevalence of SMC and the factors associated with it among Maule Cohort (MAUCO) participants.

METHODS

We performed a cross-sectional analysis to estimate the prevalence of SMC and investigated its associated factors from MAUCO baseline data (N = 6,687). Within groups defined by age (38-59, 60-74) and global cognition (Mini-Mental State Examination: ≥26, 25-22, ≤21), multinomial logistic regression models evaluated risk factors for SMC (Yes, Sometimes, No).

RESULTS

Overall, SMC prevalence was 16.4%; 15.9% (95% CI 14.9-16.9%) among younger and 17.6% (15.8-19.4%) among older participants. Female sex, comorbidities, and bad/fair self-reported health status (SRHS) were generally associated with higher odds of SMC.

CONCLUSION

Overall prevalence of SMC was 16%. Different factors were associated with the odds of SMC depending on age and global cognitive status. Future SMC studies should include sex-specific assessments, evaluate SRHS as a moderator of SMC reporting, and the influence of the SARS-CoV-2 pandemic on SMC reporting.

Test-Retest Reliability and Random Measurement Error of the Multifactorial Memory Questionnaire in Older Adults With Subjective Memory Complaints

To examine the psychometric properties of the Multifactorial Memory Questionnaire (MMQ) in older adults with subjective memory complaints. The three MMQ subscale (Satisfaction, Ability, and Strategy) was administered twice, with a 3-month interval. The test-retest reliability was examined using intraclass correlation coefficients (ICCs). The random measurement error was examined by calculating the standard error of measurement (SEM) and minimal detectable change (MDC95). The test-retest reliabilities of the three MMQ subscales were generally acceptable. The SEM of the three MMQ subscales was higher than the acceptable criterion of 10%. Despite the influence of random measurement error, the change scores of the three MMQ subscales may represent true changes if they are larger than the MDC95 of 13.2 (Satisfaction), 18.4 (Ability), and 16.9 (Strategy). The MMQ appears to be a reliable measure for use in research settings, but may not yet be suitable for clinical use.

Social determinants of memory change: A three-year follow-up of the Canadian Longitudinal Study on Aging (CLSA)

OBJECTIVES

Changes in memory can interfere with activities of daily living and may be indicative of serious health concerns such as mild cognitive impairment or dementia. Risk factors for cognitive decline and dementia have been shown to cluster around inequalities, suggesting that minority groups may be at an increased risk for cognitive decline. We sought to clarify the relationship between social determinants and change in memory function over a 3-year follow-up period, after accounting for demographic and health variables.

METHODS

We used baseline and first follow-up data from the Canadian Longitudinal Study on Aging (CLSA). Our primary analysis consisted of a multivariable linear regression model (n = 30,475). Demographic, health, education and occupation, social support, social identity, and social positioning variables (predictors) were measured at baseline. We computed a reliable change index (outcome) using the Rey Auditory Verbal Learning Test (RAVLT).

RESULTS

Older age and some health considerations (e.g., higher body mass index, low hearing) were associated with a greater decline in memory over the three-year period. In contrast, some physical activity and better self-rated general health were associated with improvements in memory. Having a hobby and better perceived social standing were associated with greater memory improvement. Social identities who experience minority stress (sexual orientation, gender identity, and race) did not predict change in memory.

DISCUSSION

Altogether, these results contribute to a growing body of evidence that points to older members of minoritized communities exhibiting initial differences in cognitive functioning (i.e., cross-sectional differences) but not more rapid cognitive aging.

Cognitive Function Trajectories and Factors among Chinese Older Adults with Subjective Memory Decline: CHARLS Longitudinal Study Results (2011-2018)

Older adults with subjective cognitive decline are at increased risk of future pathological cognitive decline and dementia. Subjective memory decline is an early sign of cognitive decline; preventing or slowing cognitive decline in at-risk populations remains an elusive issue. This study aimed to examine the cognitive trajectories and factors in older adults with subjective memory decline. Latent growth curve models (LGCMs) were fitted to examine the cognitive function trajectories and factors among 1465 older adults (aged 60+ years) with subjective memory decline. Data were obtained from four waves from the China Health and Retirement Longitudinal Study (CHARLS, 2011-2018), which is a large nationally representative sample of the Chinese population. The results showed that older adults with better initial cognition had a slower decline rate, which may be accelerated by advanced age, low-level education, a rapid decrease in instrumental activities of daily living (IADL) ability, and rapid increase in depression levels. This study was the first to examine the trajectories of cognitive function and its factors in a high-risk population with subjective memory decline. These findings may guide prevention approaches to tackle the issues of cognitive function decline and dementia.

Subjective memory complaints and social participation among older adults: results from the health and retirement study

Objectives:This study aims to examine whether subjective memory complaints (SMC) contribute to social participation among older adults.Method:The study sample was 4,713 community-dwelling older adults aged 65 years and older from four waves (2010, 2012, 2014, 2016) of the Health and Retirement Study. Hierarchical linear modeling analysis was used to examine the association of SMC with social participation after controlling for factors influencing social participation. Demographic factors (i.e. age, gender, and perceived socioeconomic status) were entered in block 1, health-related factors (i.e. health conditions, perceived health, instrumental activities of daily living, memory-immediate and delayed, and depressive symptoms) were entered in block 2, environmental factors (i.e. perceived social support and strain from spouse, child, family, and friend) were entered in block 3, and SMC was entered in block 4.Results:The result showed that factors significantly contributing to social participation are age (standardized β = -0.08, p < 0.01), perceived socioeconomic status (β = 0.16, p < 0.001), perceived health (β = 0.15, p < 0.001), instrumental activities of daily living (β = 0.12, p < 0.001), memory-immediate and delayed (β = 0.09, p < 0.001; β = 0.08, p < 0.001, respectively), social support from spouse and friend (β = 0.04, p < 0.05; β = 0.13, p < 0.001, respectively), social strain from friend (β = 0.07, p < 0.001), and SMC (β = -0.05, p < 0.001). The demographic factors explained 9.5%, health-related factors explained 8.5%, environmental factors explained 2.4%, and SMC explained 0.1% of the variance in social participation.Conclusion: This finding suggests that SMC may contribute to social participation in older adults.Supplemental data for this article can be accessed online at https://doi.org/10.1080/13607863.2021.1961123 .

Difficulties in the Use of Everyday Technology among Older Adults with Subjective Memory Complaint and Cognitive Decline

INTRODUCTION

The ability to use everyday technology (ET) is becoming increasingly necessary for maintaining domestic and social lives. For older adults, difficulties with using ETs can begin at the mild cognitive impairment (MCI) state and may indicate increasing cognitive decline. The aim of this study was to conduct a detailed investigation into the ability to use ETs among Japanese older community-dwelling adults at 3 stages of cognitive function and the ability to carry out daily activities.

METHOD

We analyzed family members' responses to questions about older adults with cognitive decline in their families. A total of 168 older adults with subjective memory complaints (SMC) or cognitive decline and inconvenience in daily life were analyzed. A questionnaire was used to assess the characteristics, ability to use ETs, and ability to manage refrigerator contents, all of which can be early signs of dementia. Participants were divided 3 groups by the type of dementia: SMC (n = 77), MCI (n = 36), and Alzheimer's disease (AD) (n = 55) for comparison.

RESULT

The observation list of early signs of dementia (OLD) total score indicated a significant positive correlation with the number of ET errors (r = 0.37, p < 0.001) and number of difficulties with refrigerator management (r = 0.18, p = 0.031). Regarding number of ET errors, there was a significant main effect for the 3 groups, and the SMC group made significantly fewer errors than the AD group (p = 0.02). In 7 of the 11 ET categories, errors with using ETs were associated with all 3 groups, with the SMC group making fewer errors, and the AD group making more. Regarding difficulties with refrigerator management, 2 out of 9 problems were associated with the 3 groups, with the SMC group having fewer difficulties and the AD group having more.

DISCUSSION/CONCLUSION

The results indicated that the ability to use ETs and to manage refrigerator contents begins to decline at the SMC stage. Further evaluation of the ability to use ETs is needed for older adults with SMC so that adequate support in the context of the individual can be provided.

Subjective cognition in adults with common psychiatric classifications; a systematic review

The aim is to assess whether instruments developed to measure subjective cognitive complaints (SCCs) and in neurology and aging can reliably be used in ADHD and other common psychiatric classifications. MEDLINE, PsycINFO, CINAHL and EMBASE+EMBASE CLASSIC were searched for relevant work on SCCs in psychiatric classifications (ADHD, autism, mood disorders, schizophrenia) in two phases: 1 identify instruments, 2 relevant studies. 35 studies with varying study quality were included. SCCs are most commonly studied in ADHD and mood disorders, but are found in all psychiatric classifications. SCCs show inconsistent and low associations to objective cognition across disorders, but higher and consistent relations are found with behavioral outcomes. SCCs are not qualitatively different for ADHD compared to other psychiatric classifications, and should thus not be seen as analogous to well validated measures of objective cognition. However, SCCs do reflect suffering, behavioral difficulties and problems experienced by across those with psychiatric problems in daily life.

Subjective cognitive complaints and relations to objective cognitive performance among Lebanese patients with schizophrenia

BACKGROUND

Patients with schizophrenia have a particularly low level of insight into their illness compared to people with other mental health disorders. The objectives of the study were to evaluate: 1) subjective cognitive complaints in individuals with schizophrenia in comparison with health controls, 2) the relation between subjective cognitive complaint (SCC) and objective cognitive performance in the patients group, and 3) factors related to cognitive complaint, such as depression, insight, autonomy, and psychological symptoms.

METHODS

Cross-sectional study was conducted between July 2019 and March 2020 enrolled 120 patients with schizophrenia disorders, selected from the Psychiatric Hospital of the Cross (HPC) - Lebanon and 60 healthy controls. The Self-Assessment Scale of Cognitive Complaints in Schizophrenia (SASCCS) was used to measure people living with schizophrenia perception of their cognitive impairment, while the Brief Assessment of Cognition in Schizophrenia (BACS) was used to evaluate their cognitive functioning.

RESULTS

A significant difference was found between schizophrenia patients and healthy controls in all neurocognition and SASCCS tests. The hierarchical regression analysis showed that the BACS total score (Beta = -.06, p = .04), the PANSS general psychopathology (Beta = .29, p = .003), higher depression (Beta = .75, p = .003) were significantly associated with higher SCC. However, higher autonomy (Beta = - 6.35, p = .001) was significantly associated with lower SCC. A Structural equation model showed that the two most contributing variables were general psychopathology (Standardized Beta (SB): .33, p < 0.001) and autonomy (SB: -.29, p < 0.001).

CONCLUSION

A significant proportion of patients with schizophrenia could estimate their cognitive impairment. It also showed a positive correlation between depression and activity of daily living with SCC, suggesting that this aspect should be investigated alongside the clinical symptoms when a patient with schizophrenia presents with SCC.

One-Year Changes in Activities of Daily Living, Usability, Falls and Concerns about Falling, and Self-Rated Health for Different Housing Adaptation Client Profiles

The purpose of this study was to investigate one-year changes and differences in changes in activities of daily living (ADL), usability, a history of falls, concerns about falling, and self-rated health across five housing adaptation (HA) client profiles identified previously using a cluster analysis approach: older adults with low level of disability (n = 59); older adults with medium/high level of disability (n = 26); adults with low level of disability (n = 10); adults with high level of disability (n = 8); and older adults with medium level of disability including at least moderate cognitive impairment (n = 5). Comparisons between the five profiles include secondary analyses aggregating those with low level of disability and those with medium/high level of disability. Changes within the client profiles demonstrate a complex pattern of improvements and declines, depending on outcome, with no profile showing consistent improvement or decline across all outcomes. The risks of deterioration over one year were the highest among those with cognitive impairments at baseline, but no recommendation of prioritization decisions based on baseline profiles can be made. Instead, it seems that all HA clients, independently of baseline profile, are at risk of increasing disability over time and require follow-up evaluations regularly.

Longitudinal trajectories of physical functioning among Chinese older adults: the role of depressive symptoms, cognitive functioning and subjective memory

BACKGROUND AND OBJECTIVE

Maintaining physical functioning (i.e. mobility, activities of daily living [ADLs], instrumental activities of daily living [IADLs]) in older adults is essential for independent living. However, little is known about how longitudinal trajectories of physical functioning differ by varying levels of depressive symptoms, subjective memory impairment and cognitive functioning. We aimed to examine whether, and to what degree, the rate of change in physical functioning over time was associated with depressive symptoms, subjective memory and cognitive functioning.

DESIGN

A correlational longitudinal design.

METHODS

The sample included 5,519 older adults (mean age = 68.13 years) from the China Health and Retirement Longitudinal Study (three waves: 2011-15) who self-reported their depressive symptoms, subjective memory impairment and physical functioning. Cognitive functioning was assessed through interview-based tests.

RESULTS

There were significant increases in mobility impairment (β = 0.27, P < 0.001), ADLs impairment (β = 0.05, P < 0.001) and IADLs impairment (β = 0.03, P = 0.006) over time. Compared with the mean score at baseline in 2011, the mobility, ADLs and IADLs impairment increased by 13.32, 10.57 and 4.34% for every 2 years, respectively. Those with high depressive symptoms had accelerated rates of mobility (β = 0.212, P < 0.001), ADLs (β = 0.104, P < 0.001) and IADLs impairment (β = 0.076, P = 0.002). Those with poorer cognitive functioning had more rapid rates of mobility impairment. In contrast, those with differing levels of subjective memory impairment did not experience different physical functioning trajectories.

CONCLUSIONS

High depressive symptoms and poor cognitive functioning may be precursors to rapid declines in physical functioning. Proactive screening for these precursors may attenuate physical decline among Chinese older adults.

Housing and Care for Older Women in Australia

Background: Housing is essential for healthy ageing, being a source of shelter, purpose, and identity. As people age, and with diminishing physical and mental capacity, they become increasingly dependent on external supports from others and from their environment. In this paper we look at changes in housing across later life, with a focus on the relationship between housing and women's care needs.

Methods: Data from 12,432 women in the 1921–26 cohort of the Australian Longitudinal Study on Women's Health were used to examine the interaction between housing and aged care service use across later life.

Results: We found that there were no differences in access to home and community care according to housing type, but women living in an apartment and those in a retirement village/hostel were more likely to have an aged care assessment and had a faster rate of admission to institutional residential aged care than women living in a house. The odds of having an aged care assessment were also higher if women were older at baseline, required help with daily activities, reported a fall, were admitted to hospital in the last 12 months, had been diagnosed or treated for a stroke in the last 3 years, or had multiple comorbidities. On average, women received few services in the 24 months prior to admission to institutional residential aged care, indicating a potential need to improve the reach of these services.

Discussion: We find that coincident with changes in functional capacities and abilities, women make changes to their housing, sometimes moving from a house to an apartment, or to a village. For some, increasing needs in later life are associated with the need to move from the community into institutional residential aged care. However, before moving into care, many women will use community services and these may in turn delay the need to leave their homes and move to an institutional setting. We identify a need to increase the use of community services to delay the admission to institutional residential aged care.

Subjective Memory Complaints and Sensitivity of the Subjective Memory Complaint Questionnaire in Post-Stroke Dementia Patients

INTRODUCTION

Subjective memory complaints (SMCs) among stroke patients are common. To date, reports on SMCs using the Subjective Memory Complaint Questionnaire (SMCQ) are limited. We provided descriptive information on SMCs using the SMCQ alongside objective neuropsychological function assessment in stroke patients and established the sensitivity of SMCQ for post-stroke dementia.

METHODS

In total, 419 consecutive stroke patients who were admitted to a stroke unit for younger populations (age <65 years) at a rehabilitation hospital from June 1, 2014, to January 1, 2020, were reviewed. SMCs were measured using the SMCQ. Objective neuropsychological function was assessed using protocols of the Vascular Cognitive Impairment Harmonization Standards.

RESULTS

SMCs were significantly correlated with objective neuropsychological functions including memory, executive function, language, and depression. SMCs were not significantly correlated with visuospatial function. The SMCQ exhibited comparable sensitivity to that of Mini-Mental Status Examination for evaluating post-stroke dementia.

CONCLUSIONS

The SMCQ may be a valid measure of cognitive function among patients with stroke, is sensitive for post-stroke dementia, and may assume a complementary role for assessing patients with stroke.

The Nexus of Sensory Loss, Cognitive Impairment, and Functional Decline in Older Adults: A Scoping Review

BACKGROUND AND OBJECTIVES

The prevalence of cognitive impairment and sensory loss in hearing or vision increases with age. Based on the Information Processing Model, cognitive impairment coupled with sensory loss may exacerbate disability in late life. Yet this issue has not been systematically studied. The purpose of this scoping review was to examine the literature that studied the relationship between cognitive impairment, sensory loss, and activities of daily living in older adults.

RESEARCH DESIGN AND METHODS

Two reviewers independently screened 1,410 studies identified from five electronic databases (Medline, EMBASE, PsycINFO, CINHAL, and the Web of Science). The search was completed in June 2020. A study was eligible if it included measurements of cognitive function, vision or hearing, and activities of daily living. Additionally, the data analyses must address how cognitive impairment and sensory loss are related to the performance of activities of daily living.

RESULTS

The final review included 15 studies. Findings show an additive effect of cognitive impairment and sensory loss on the activities of daily living. Cognitive impairment or vision loss independently relates to the decline in activities of daily living. Hearing loss relates to the decline only when the loss is severe, or if the daily task is hearing specific.

DISCUSSION AND IMPLICATIONS

Older adults with coexisting sensory loss and cognitive impairment have the highest risk or prevalence of disability, comparing to cognitive impairment or sensory loss alone. This finding highlights the importance of developing interventions to reduce the risk of disability for older adults experiencing multiple impairments.

Functional Differences Found in the Elderly Living in the Community

Introduction: Successful aging lies in cognitive and functional maintenance, and in the optimal performance of daily tasks that keep the elderly free of disability and dependence. However, there is little evidence for functional differences for gender and age, and how cognitive and physical demands in past working lives can affect them, to design more personalized occupational therapy interventions to prevent functional and cognitive impairment. Method: This observational descriptive study evaluated 367 older adults living in a community with subjective memory complaints and scored between 24 and 35 with the Spanish version of the “Mini-Mental State Examination (MEC-35)”. Basic activities of daily living (BADL) were studied with the Barthel Index, while instrumental ADL (IADL) were examined with the Lawton–Brody scale. Functional differences for gender, age, and physico-mental occupation were examined. Results: The significant differences found for gender indicated that men did better in BADL (p = 0.026) and women better performed IADL (p < 0.001). Differences between age groups suggest that the younger group (aged 64–75) obtained better results for BADL (p = 0.001) and IADL (p < 0.001). For physico-mental occupation, statistically significant differences were found only in IADL for mental (p = 0.034) and physical occupation (p = 0.005). Conclusions: Gender, age, and the cognitive and physical demands of occupational stages, can be important predictors of cognitive and functional impairment. These results can be generalized to other health centers in the province and to other Spanish Autonomous Communities because their socio-demographic variables are similar. It would be interesting to carry out multimodal personalized interventions that consider the factors that might affect functional impairment to preserve personal autonomy.

The mediating and moderating effects of depression on the relationship between cognitive function and difficulty in activities of daily living among postmenopausal women

OBJECTIVE

Cognitive function and depression impact critically the daily functioning of menopausal women. This study aimed to explore the mediating and moderating effects of depressive symptoms on the association between cognitive function and activities of daily living (ADL) difficulty in postmenopausal women.

METHODS

A total of 2,596 postmenopausal women from the China Health and Retirement Longitudinal Study completed the Chinese version of the Mini-Mental State Examination, basic ADL (BADL) and instrumental ADL (IADL) scales, and 10-item Short-Form Center for Epidemiological Studies Depression. We constructed structural equation modeling to examine the association between cognitive function, depressive symptoms, and BADL/IADL difficulty.

RESULTS

The prevalence of BADL/IADL difficulty in postmenopausal women was 22.5% and 31.5%, respectively. After adjustments for demographic and health-related covariates, cognitive decline (contributed by four cognitive dimensions with different weights) was significantly associated with BADL/IADL difficulty (contributed by six-item daily activities with different weights). Depressive symptoms mediated and explained 28.8% and 23.2% of cognitive function associations with BADL and IADL difficulty, respectively. The Johnson-Neyman technique identified a threshold of eight and four for depressive symptoms, beyond which the protective effect of cognitive function on BADL and IADL emerged.

CONCLUSIONS

Depressive symptoms mediated and moderated the association between cognition and BADL/IADL difficulty in postmenopausal women. Compared with BADL, IADL may be more sensitive to changes in cognitive function. More strength should be put on developing comprehensive intervention techniques focusing on simultaneous intervention of multidimensional cognitive function and depression to maintain and improve the quality of life of postmenopausal women.

Association between Daily Activities and Behavioral and Psychological Symptoms of Dementia in Community-Dwelling Older Adults with Memory Complaints by Their Families

It is important and useful to consider information provided by family members about individuals with memory complaints' instrumental activities of daily living (IADL). The purpose of this study was to clarify the characteristics and relevance of individuals with memory complaints' IADL and behavioral and psychological symptoms of dementia (BPSD) assessed from the perspective of the family members using the Process Analysis of Daily Activity for Dementia and short version Dementia Behavior Disturbance scale. A self-administered questionnaire was sent to 2000 randomly selected members of Consumer's Co-operative Kagoshima, and 621 responded. Of the returned responses, there were 159 participants who answered about individuals with memory complaints. The stepwise multiple regression analysis was used to examine the association between IADL and BPSD. The result showed that many IADL of the individuals with memory complaints were associated with BPSD of apathy, nocturnal wakefulness, and unwarranted accusations, adjusted for age, gender, and the observation list for early signs of dementia. In addition, each IADL was associated with BPSD of apathy, nocturnal wakefulness, and dresses inappropriately. Modifying lifestyle early on when families recognize these changes may help maintain and improve the long-term quality of life of the individuals with memory complaints and their family.

Instrumental Activities of Daily Living: The Processes Involved in and Performance of These Activities by Japanese Community-Dwelling Older Adults with Subjective Memory Complaints

Subjective memory complaints (SMCs) may predict the onset of dementia. The purpose of this study was to clarify characteristics of performance of activities of daily living (ADL) for older adults with SMCs and to offer support options that enable them to maintain their community-based lifestyle. A self-administered questionnaire was sent to 2000 randomly selected members of CO-OP Kagoshima, and 621 responded. 270 responders answered all questions were categorized into SMC (+) group and SMC (−) group (n = 133). Participants were evaluated the Process Analysis of Daily Activity for Dementia. A 2-sample t-test or the Chi-square test were used to compare the averages of continuous variables or the proportions of categorical variables. The results showed the SMC (+) group ranked significantly lower in ability to use the telephone, shop, cook, do housekeeping, manage finances, and manage medications compared with the SMC (−) group. In addition, the SMC (+) group was significantly less independent than the SMC (−) group in many processes requiring the use of tools, operation of machines, management of goods, selection of tools, and monitoring. To enable continued independence of older adults’ experiencing SMCs, it may be important to analyze their performance of ADL and to develop plans for supporting their strengths.
