Change in leisure and social activities and risk of dementia in elderly cohort

Neuropsychological Effects of the Lockdown Due to the COVID-19 Pandemic on Patients with Alzheimer's Disease and Their Caregivers: The "ACQUA" (Alzheimer-COVID QUArantine Questionnaire) Study

BACKGROUND

The lockdown due to the COVID-19 pandemic, imposed in many countries in 2021, led to social isolation and the interruption of many activities that were useful in stimulating cognition. The impact of these changes has been particularly severe in older subjects with cognitive impairment.

METHODS

The present study aimed to investigate the effects of lockdown on Alzheimer's disease patients (in cognition, behavior, and autonomy) and on their caregivers (in emotions, burden, and quality of life). We created a questionnaire and performed an extensive semi-structured telephone interview with each caregiver. The main outcomes were (1) changes in cognitive and behavioral symptoms and autonomy levels in the patients and (2) effects on caregivers' emotions, burden, and quality of life.

RESULTS

The lockdown severely impaired patients' cognition and independence and worsened behavioral and psychological symptoms of dementia. These effects contributed to increasing caregivers' burden and stress levels, with a significant perceived deterioration in quality of life among caregivers with higher education levels (p = 0.047).

CONCLUSIONS

This study might contribute to our understanding of the impact of lockdown on Alzheimer's disease patients and their caregivers, to guide future public health interventions aimed at preventing and/or reducing the consequences of similar extraordinary events in frail subjects.

Counseling in menopausal women: How to address the benefits and risks of menopause hormone therapy. A FIGO position paper

Menopause marks the end of menstrual cyclicity and, depending on individual vulnerability, has several consequences related to gonadal steroid deprivation, especially if it is premature. Menopause may be more burdensome for some women than for others. Individual factors, such as personal history, socioeconomic status, ethnicity, and current health conditions, affect symptomatology and, thereby, the menopausal experience. In addition, some menopausal symptoms, such as severe hot flashes, sleep disorders, and depression, are markers of future health risks. Counseling is a fundamental part of health care in the peri- and postmenopause periods. It must include an assessment of the patient's symptoms, needs, desires, and risk profile to address the benefits and risks of menopausal hormone therapy (MHT) on an individual basis and promote a healthy lifestyle. Indeed, healthcare practitioners can and must protect the health and lives of mid-life women by increasing awareness of menopausal symptoms and ensuring healthcare options, especially MHT. The type and duration of MHT should be tailored based on the patient's history, menopausal age, physical characteristics, and current health status so that the benefits always outweigh the risks. This FIGO position paper focuses on the benefits and risks of MHT on health domains, target organs, and systems, and on systemic and vaginal MHT regimens, to provide indications that can be used in the clinical practice for menopausal counseling. Moreover, it offers insights into what FIGO considers the mainstay for the healthcare management of women in peri- and postmenopause, worldwide.

The perspectives of older adults with mild cognitive impairment and their caregivers on the use of socially assistive robots in healthcare: exploring factors that influence attitude in a pre-implementation stage

BACKGROUND

Due to increasing age and an increasing prevalence rate of neurocognitive disorders such as Mild Cognitive Impairment (MCI) and dementia, independent living may become challenging. The use of socially assistive robots (SARs) is one solution that can enable older adults with cognitive impairment to remain independent. However, at present, there is a lack of knowledge about the attitudes of older adults with MCI and their caregivers towards SARs.

METHODS

This study relies on a constructivist grounded theory approach. Semi-structured interviews were conducted to gain a deeper insight into attitudes of two different stakeholder groups; older adults with MCI and their (in)formal caregivers.

RESULTS

Forty individual semi-structured interviews were conducted with older adults with MCI (N = 30) and (in)formal caregivers (N = 10). Data revealed different perspectives on SARs in healthcare for the involved stakeholders. Two main topics could be derived: (1) perspectives on robot assistance, discussing different viewpoints on the potential value of robots as helpers, and (2) perspectives on implementation, revealing different factors that could affect implementation. Both topics may explain a positive, impartial or negative attitude towards SARs.

CONCLUSIONS

This study identified different factors that should be taken into account when implementing a SAR in the home environment of older adults. Despite the fact that the benefits of SARs are often recognized, many older participants currently seem not ready yet to commit to the use of a SAR.IMPLICATIONS FOR REHABILITATIONThis study explores the attitudes towards a SAR, developed to stimulate and support older adults with Mild Cognitive Impairment (MCI) on a physical, cognitive and social level.The results give a deeper insight into different factors contributing to a (non-) successful implementation of SARs in the home environment of older adults with MCI.

Sociodemographic Factors Predict Incident Mild Cognitive Impairment: A Brief Review and Empirical Study

OBJECTIVES

Mild cognitive impairment (MCI) is a transitional stage between normal cognitive aging and dementia that increases the risk of progressive cognitive decline. Early prediction of MCI could be beneficial for identifying vulnerable individuals in the community and planning primary and secondary prevention to reduce the incidence of MCI.

DESIGN

A narrative review and cohort study.

SETTING AND PARTICIPANTS

We review the MCI prediction based on the assessment of sociodemographic factors. We included participants from 3 surveys: 8915 from wave 2011/2012 of the China Health and Retirement Longitudinal Study (CHARLS), 9765 from the 2011 Chinese Longitudinal Healthy Longevity Survey (CLHLS), and 1823 from the 2014 Rugao Longevity and Ageing Study (RuLAS).

METHODS

We searched in PubMed, Embase, and Web of Science Core Collection between January 1, 2019, and December 30, 2022. To construct the composite risk score, a multivariate Cox proportional hazards regression model was used. The performance of the score was assessed using receiver operating characteristic (ROC) curves. Furthermore, the composite risk score was validated in 2 longitudinal cohorts, CLHLS and RuLAS.

RESULTS

We concluded on 20 articles from 892 available. The results suggested that the previous models suffered from several defects, including overreliance on cross-sectional data, low predictive utility, inconvenient measurement, and inapplicability to developing countries. Our empirical work suggested that the area under the curve for a 5-year MCI prediction was 0.861 in CHARLS, 0.797 in CLHLS, and 0.823 in RuLAS. We designed a publicly available online tool for this composite risk score.

CONCLUSIONS AND IMPLICATIONS

Attention to these sociodemographic factors related to the incidence of MCI can be beneficially incorporated into the current work, which will set the stage for better early prediction of MCI before its incidence and for reducing the burden of the disease.

Topical Review of Hobbies and Cognitive Health

BACKGROUND

Establishing preventive measures to improve cognitive health of the growing older adult population is a public health priority. Though, the links between low-cost non-pharmacologist interventions that target activities like hobbies and cognitive health remain unclear.

OBJECTIVE

We conducted a topical review of extant literature to characterize prior findings in context and identify potential research opportunities.

METHODS

Search criteria was conducted with search terms "Hobbies and Dementia", "Hobbies and Cognitive Health," "Leisure Activities and Dementia," and "Leisure Activities and Cognitive Health". From the initial 383 articles, 25 articles were selected for review by using broad inclusion and exclusion criteria.

RESULTS

Of the 25 articles included in this review, 19 were longitudinal cohort, 1 was a retrospective cohort, 2 were case-control, and 3 were cross-sectional. These studies classified hobbies as leisure activities that were cognitive/intellectual, cultural, religious, social, gardening, traveling, or physical. These studies were conducted in the United States (9), United Kingdom (3), Sweden (3), France (5), Finland (1), Korea (1), Japan (2), and China (1). The associations of different types of hobbies with dementia from these studies were not consistent. Inconsistencies could be due to limitations of study design, lack of standardized methods, sample diversity, and differences in factors like social/cultural environment across the study populations.

CONCLUSION

This review examined existing evidence for the association between engagement in different types of hobbies and dementia and identified key knowledge gaps and promising approaches for future research.

Cognitive impairment in daily life (CID): A double-faced instrument to detect changes and impairments in activities of daily living for people with suspected cognitive impairment

BACKGROUND

Assessment of cognitive function and its consequences for activities of daily living is an important part of a dementia evaluation. To describe patients' functional impairment accurately, a feasible instrument is needed. The Cognitive Impairment in Daily Life (CID) is an instrument developed with that purpose.

AIM

To describe and compare self- and proxy-reported difficulties in everyday life in patients undergoing a dementia investigation, measured by CID. A secondary aim was to compare the results between those who were diagnosed with dementia versus those without dementia.

METHOD

Self- and proxy-reported data using CID in 77 cases in dementia investigations. Of those, 32 were diagnosed with dementia and were compared to those without dementia (n = 45). Descriptive statistics.

RESULTS

When comparing self-reported and proxy-reported activity problems, most activities differed significantly. Proxies reported more difficulties than patients did. When comparing no dementia and dementia groups, significant differences were shown regarding initiative, planning and performance but not for memory and attention estimated by the patient themselves. Proxies differed significantly from patients in all tasks.

CONCLUSION

Overall, proxies reported that patients had more difficulties than patients reported themselves. The CID seems to be usable in dementia investigations and the results highlight the importance of involving both patients and relatives.

The role of cognitive and social leisure activities in dementia risk: assessing longitudinal associations of modifiable and non-modifiable risk factors

AIMS

With the projected surge in global dementia cases and no curative treatment available, research is increasingly focusing on lifestyle factors as preventive measures. Social and cognitive leisure activities are promising targets, but it is unclear which types of activities are more beneficial. This study investigated the individual and joint contribution of cognitive and social leisure activities to dementia risk and whether they modify the risks associated with other potentially modifiable and non-modifiable risk factors.

METHODS

We used data from the English Longitudinal Study of Ageing (ELSA) from 7917 participants, followed up from 2008/2009 (Wave 4) until 2018/2019 (Wave 9) for incident dementia. Self-reported baseline cognitive activities (e.g. 'reading the newspaper'), the number of social memberships (e.g. being a member of a social club) and social participation (e.g. 'going to the cinema') were clustered into high and low based on a median split. Subsequently, their individual and joint contribution to dementia risk, as well as their interaction with other dementia risk factors, were assessed with Cox regression models, adjusting for age, sex, level of education, wealth and a composite score of 11 lifestyle-related dementia risk factors.

RESULTS

After a median follow-up period of 9.8 years, the dementia incidence rate was 54.5 cases per 10.000 person-years (95% CI 49.0-60.8). Adjusting for demographic and other lifestyle-related risk factors, higher engagement in cognitive activities (HR = 0.58; 95% CI 0.40-0.84), a greater number of social memberships (HR = 0.65; 95% CI 0.51-0.84) and more social participation (HR = 0.71; 95% CI 0.54-0.95) were associated with lower dementia risk. In a joint model, only engagement in cognitive activities (HR = 0.60; 95% CI 0.40-0.91) and social memberships (HR = 0.75; 95% CI 0.56-0.99) independently explained dementia risk. We did not find any interaction with other modifiable and non-modifiable risk factors.

CONCLUSIONS

Engagement in cognitive and social leisure activities may be beneficial for overall dementia risk, independent of each other and other risk factors. Both types of activities may be potential targets for dementia prevention measures and health advice initiatives.

Types of social networks and starting leisure activities in later life: A longitudinal Japan Gerontological Evaluation Study (JAGES)

Considering beneficial effects of leisure activities in later life on well-being and health, we investigated which type of social network among older adults is associated with starting their participation in leisure activities. We used data from a longitudinal Japan Gerontological Evaluation Study (JAGES) conducted in Japan every three years from 2010 to 2016. We extracted types of social networks of older adults who did not participate in leisure activities in 2013 and responded to items related to social networks (n = 3436) relying on latent class analysis to examine changes in leisure activity participation over a three-year period within each latent class while controlling for participants' activity in 2010. As a result, we identified five latent classes of social networks: the Neighborhood network, the Restricted network, which is characterized by limited social contacts, the Colleagues network, the Same-Interest network, and the Diverse network, from the most to the least prevalent. We found that members of the Neighborhood (Cohen's d = 0.161) and Same-Interest networks (d = 0.660) were significantly more likely to, and members of the Diverse (d = 0.124) and Colleague networks (d = 0.060) were not significantly more likely to start leisure activities than those in the Restricted network. Furthermore, we found that lower age, better mental health, and higher education level were positively associated with starting participation in leisure activities in some latent classes. Horticulture or gardening was most likely to be chosen across all latent classes. Supporting the formation of social networks facilitating leisure activities, and recommending activities that were likely to be selected could be one solution for getting and keeping older adults active.

Prospective pragmatic quasi-experimental study to assess the impact and effectiveness of an innovative large-scale public health intervention to foster healthy ageing in place: the SoBeezy program protocol

INTRODUCTION

With the accelerating pace of ageing, healthy ageing has become a major challenge for all societies worldwide. Based on that Healthy Ageing concept proposed by the WHO, the SoBeezy intervention has been designed through an older person-centred and integrated approach. The programme creates the environments that maximise functional ability to enable people to be and do what they value and to stay at home in best possible conditions.

METHODS AND ANALYSIS

Five levers are targeted: tackling loneliness, restoring feeling of usefulness, finding solutions to face material daily life difficulties, promoting social participation and combating digital divide. Concretely, the SoBeezy programme relies on: (1) a digital intelligent platform available on smartphone, tablet and computer, but also on a voice assistant specifically developed for people with digital divide; (2) a large solidarity network which potentially relies on everyone's engagement through a participatory intergenerational approach, where the older persons themselves are not only service receivers but also potential contributors; (3) an engagement of local partners and stakeholders (citizens, associations, artisans and professionals). Organised as a hub, the system connects all the resources of a territory and provides to the older person the best solution to meet his demand. Through a mixed, qualitative and quantitative (before/after analyses and compared to controls) approach, the research programme will assess the impact and effectiveness on healthy ageing, the technical usage, the mechanisms of the intervention and conditions of transferability and scalability.

Natural History of Social Participation in the Very Old: Findings from the Newcastle 85+ Study

Objective: To describe the natural history of social participation in people aged 85 years and over. Methods: Prospective cohort study; Newcastle 85+ study. Data were collected at baseline (n = 850) and at 18-, 36- and 60-month follow-ups (n = 344). Participation in 19 social activities (e.g. playing bingo, doing volunteer work and watching television) was measured at each time point. Results: The mean number of activities reported at baseline was 8.7 (SD 2.6). The number of activities was higher in those with higher educational attainment and intact walking ability (both p < .001). Social participation decreased significantly over time (p < .001) and at a similar rate in both sexes and for those with/without limited walking ability but at a higher rate in those with higher than lower educational attainment (p = .019). Discussion: Social participation seems to decrease significantly between ages 85 and 90 years; ways of encouraging social participation in this age group are needed.

Emotional support (giving or receiving) and risk of incident dementia: The Ohsaki Cohort 2006 Study

Previous studies have suggested that emotional support may promote cognition; however, the effects of giving or receiving emotional support on incident dementia remain unclear. Therefore, we sought to investigate the relationship between emotional support (giving or receiving) and incident dementia. In December 2006, we conducted a prospective cohort study of 31,694 Japanese individuals aged ≥65 years who lived in Ohsaki City, Miyagi Prefecture, Japan. A self-reported questionnaire including items on emotional support and lifestyle factors was distributed. After excluding those who did not provide consent or responses to all items, 13,636 eligible responses were analyzed for this study. According to responses of "yes" or "no" for emotional support, we made two categories for both giving (gave or did not give) and receiving (received or did not receive) emotional support. Furthermore, we combined giving and receiving emotional support into four categories ("giving = no & receiving = no", "giving = no & receiving = yes", "giving = yes & receiving = no", "giving = yes & receiving = yes"). Data on incident dementia were retrieved from the Long-term Care Insurance Database in which participants were followed up for 5.7 years. Using multivariate Cox proportional hazards models, we found that compared with participants who did not give emotional support to others, those who did give had a lower risk of dementia (multivariate-adjusted hazard ratio [HR]: 0.61 (95% confidence interval [CI]: 0.52, 0.71)). However, a nonsignificant relationship was observed for receiving emotional support. Additionally, compared to "giving = no & receiving = no" for emotional support, "giving = no & receiving = yes" showed a higher risk of dementia (multivariate-adjusted HR: 1.51 [95% CI: 1.07, 2.14]).

Improvement in cognitive performance and mood in healthy older adults: a multimodal approach

The aim of this research was to evaluate if being involved in a programme that integrates physical, mental, and social activities could help to reduce the impacts of cerebral ageing on cognitive functions. Fifty healthy adults over 65 years of age and without cognitive impairment were randomly assigned to either an experimental or a control group; subjects were equally divided by age, sex, schooling, physical health, mood, and social integration. For 6 months, the experimental group had biweekly meetings, participating in a multimodal approach based on a combination of simultaneous physical, mental, and social activities. At pre-test and post-test, both experimental and control subjects underwent a neuropsychological assessment, including tests to measure attention, verbal and spatial memory, language, constructional praxis, executive functions, processing speed, and intelligence. Furthermore, a visual analogue scale was used to examine well-being and mood states. Compared to the pre-test levels and the control subjects, the performance of subjects in the experimental group significantly improved in several neuropsychological tests, including attention, processing speed, memory, and executive functions, as well as mood state. Even in older subjects without cognitive impairments, a multimodal approach based on simultaneous physical, mental, and social activity can be a useful strategy that has beneficial effects on mood and cognition. The results suggest that an active lifestyle may protect against cognitive decline in ageing.

Leisure Activity, Brain β-amyloid, and Episodic Memory in Adults with Down Syndrome

The present study provided an investigation of associations between leisure activity and early Alzheimer's disease neuropathology (i.e., brain β-amyloid) and episodic memory in a sample of 65 adults with Down syndrome (aged 30-53 years), at baseline and follow-up, approximately three years apart. Findings indicated that leisure activity at baseline was not associated with brain β-amyloid at baseline or change in brain β-amyloid from baseline to follow-up. Greater cognitively stimulating leisure activity at baseline was associated with better episodic memory at baseline, and greater social leisure activity at baseline was associated with less decline in episodic memory from baseline to follow-up. High (as opposed to low) levels of social and overall leisure activity at baseline moderated the association between increase in brain β-amyloid and decline in episodic memory, from baseline to follow-up. Findings suggest that cognitively stimulating and social leisure activity could protect against the effect of Alzheimer's disease neuropathology on episodic memory in adults with Down syndrome.

Is cognitive decline in the elderly associated with contextual income? Results of a population-based study in southern Brazil

The aim of this study was to estimate the association between contextual income and cognitive decline in the elderly in Florianópolis, a medium-sized city in southern Brazil. A nested cross-sectional study was performed in a cohort of elderly ≥ 60 years (n = 1,197), interviewed in the second wave (2013/2014) of the EpiFloripa cohort. Cognitive decline was assessed with the Mini Mental State Examination (MMSE) and contextual income was measured as the mean monthly income of the heads of households. Individual adjustment variables were sex, age, skin color, per capita household income, years of schooling, and time living in the neighborhood. The data were analyzed using multilevel logistic regression. The odds of cognitive decline were twice as high (OR = 1.99; 95%CI: 1.03; 3.87) in elderly living in census tracts with the lowest income quintile compared to those in the highest quintile, independently of individual characteristics. In conclusion, the socioeconomic environment is related to cognitive decline and should be considered in public policies with a focus on health of the elderly.

Successful ageing for people with an intellectual disability

PURPOSE OF REVIEW

Successful ageing has not yet been defined in people with an intellectual disability. The purpose of this review is to discuss and define successful ageing in the context of intellectual disability and to propose strategies to improve health and wellbeing for this population.

RECENT FINDINGS

People with an intellectual disability experience higher rates of diabetes, hypertension, obesity and cardiovascular disease, and higher rates of mental disorders than people without an intellectual disability. People with an intellectual disability engage in more passive leisure activities because many active leisure activities require the participation of or assistance by others. Health promotion programmes tailored to people with an intellectual disability consisting of exercise and health education can result in more positive attitudes toward exercise and improvements in psychosocial outcomes.

SUMMARY

With modifications for people with an intellectual disability, the concept of successful ageing can be used as a template for development of strategies to improve health and wellbeing for people with an intellectual disability as they age. Targeted programmes focused on health promotion and prevention of age-related morbidities is required. There is a need for policies addressing positive ageing, including social participation and maximizing community participation. Appropriate and ongoing education for people with an intellectual disability and their carers on healthy living in areas of physical, social, and cognitive activity, nutrition and avoidance of risk factors is essential.

Association of Long-Term Dietary Fat Intake, Exercise, and Weight with Later Cognitive Function in the Finnish Diabetes Prevention Study

OBJECTIVES

To investigate associations of long-term nutrient intake, physical activity and obesity with later cognitive function among the participants in the Finnish Diabetes Prevention Study, in which a lifestyle intervention was successful in diabetes prevention.

DESIGN

An active lifestyle intervention phase during middle age (mean duration 4 years) and extended follow-up (additional 9 years) with annual lifestyle measurements, followed by an ancillary cognition assessment.

SETTING

5 research centers in Finland.

PARTICIPANTS

Of the 522 middle-aged, overweight participants with impaired glucose tolerance recruited to the study, 364 (70%) participated in the cognition assessment (mean age 68 years).

MEASUREMENTS

A cognitive assessment was executed with the CERAD test battery and the Trail Making Test A on average 13 years after baseline. Lifestyle measurements included annual clinical measurements, food records, and exercise questionnaires during both the intervention and follow-up phase.

RESULTS

Lower intake of total fat (p=0.021) and saturated fatty acids (p=0.010), and frequent physical activity (p=0.040) during the whole study period were associated with better cognitive performance. Higher BMI (p=0.012) and waist circumference (p=0.012) were also associated with worse performance, but weight reduction prior to the cognition assessment predicted worse performance as well (decrease vs. increase, p=0.008 for BMI and p=0.002 for waist).

CONCLUSIONS

Long-term dietary fat intake, BMI, and waist circumference have an inverse association with cognitive function in later life among people with IGT. However, decreases in BMI and waist prior to cognitive assessment are associated with worse cognitive performance, which could be explained by reverse causality.

Social activity, cognitive decline and dementia risk: a 20-year prospective cohort study

BACKGROUND

Identifying modifiable lifestyle correlates of cognitive decline and risk of dementia is complex, particularly as few population-based longitudinal studies jointly model these interlinked processes. Recent methodological developments allow us to examine statistically defined sub-populations with separate cognitive trajectories and dementia risks.

METHODS

Engagement in social, physical, or intellectual pursuits, social network size, self-perception of feeling well understood, and degree of satisfaction with social relationships were assessed in 2854 participants from the Paquid cohort (mean baseline age 77 years) and related to incident dementia and cognitive change over 20-years of follow-up. Multivariate repeated cognitive information was exploited by defining the global cognitive functioning as the latent common factor underlying the tests. In addition, three latent homogeneous sub-populations of cognitive change and dementia were identified and contrasted according to social environment variables.

RESULTS

In the whole population, we found associations between increased engagement in social, physical, or intellectual pursuits and increased cognitive ability (but not decline) and decreased risk of incident dementia, and between feeling understood and slower cognitive decline. There was evidence for three sub-populations of cognitive aging: fast, medium, and no cognitive decline. The social-environment measures at baseline did not help explain the heterogeneity of cognitive decline and incident dementia diagnosis between these sub-populations.

CONCLUSIONS

We observed a complex series of relationships between social-environment variables and cognitive decline and dementia. In the whole population, factors such as increased engagement in social, physical, or intellectual pursuits were related to a decreased risk of dementia. However, in a sub-population analysis, the social-environment variables were not linked to the heterogeneous patterns of cognitive decline and dementia risk that defined the sub-groups.
