Risk and protective factors of a wish to die and suicidal ideation in community-dwelling, older, Flemish adults: results of the Belgian ageing studies

OBJECTIVES

This study aims to increase the understanding of suicidality in older adults by investigating the prevalence, characteristics, risk and protective factors of suicidal phenomena in community-dwelling older adults (60+) in Flanders, specifically of a current wish to die (WTD) and lifetime suicidal ideation and behaviour (LSIB).

METHOD

Cross-sectional data from the Belgian Ageing Studies (BAS) is used (N = 3050). The BAS aims to monitor the needs and quality of life of community-dwelling older adults through a standardised survey. Statistical methods used are bivariate analyses and binary logistic regression.

RESULTS

Prevalence rates of 4.8% for WTD and 8.2% for LSIB are found. LSIB is the biggest predictor of a current WTD, followed by requiring support on three domains, elder abuse, depression and subjective cognitive complaints, and elder abuse were significant risk factors for both WTD and LSIB. Limited effects of protective factors were found.

CONCLUSION

Previous research regarding risk factors to be confirmed in this study, and new insights on the effect of elder abuse, subjective indicators of cognitive complaints and requiring support are added. Further research into protective factors and underlying mechanisms is required.

Impact of COVID-19 on Physical Activity, Fatigue, and Frailty in Community-Dwelling Older Adults: A Cross-Sectional Study

This study aimed to describe the level of physical activity and its relation to fatigue and frailty during the COVID-19 pandemic in community-dwelling older adults aged 80 years and over. Three hundred and ninety-one older adults (aged 86.5 ± 3.00) completed a survey including physical activity, the Mobility Tiredness scale, and the FRAIL scale. Linear regression analysis was conducted to assess whether the variables age, sex, and physical activity (independent factors) were significantly related to fatigue and frailty. Respectively, 30.5% and 24.7% of the participants reported a decrease in walking and in energy-intensive activities; 25.4% reported increased sedentary behavior. A lower level of physical activity was associated with higher levels of fatigue and increased frailty risk (p < .05), independently from psychological symptoms. These results are important because participants with lower levels of physical activity and more sedentary behavior are more likely to feel fatigued and have higher risk to be frail.

The Vulnerability of Older Informal Caregivers with Care Needs: Significance of Multidimensional Frailty

OBJECTIVES

To improve our understanding of older informal caregivers' (ICs) health, this paper aimed to compare multidimensional frailty and sociodemographic and economic characteristics between (subgroups of) older ICs and non-caregivers.

METHODS

Using data originating from the Belgian Ageing studies (n = 6054), intergroup differences between older ICs and non-caregivers and between care-dependent and -independent older ICs/non-caregivers were conducted. In addition binary logistic regressions were carried out to determine which variables were related to caregiver status and need of assistance.

RESULTS

Among all respondents, 14.3% were ICs reporting care needs themselves. Informal and non-caregivers with care needs, relative to those without, more often only (partially) completed primary education, were significantly older, more likely to be female and widowed, found it more difficult to make ends meet, and reported higher levels of frailty in each domain. Moreover, environmental and psychological frailty were associated with an increase in the likelihood of reporting need of assistance among older non-caregivers and ICs, respectively.

CONCLUSIONS

This study revealed a particular vulnerable subpopulation of older ICs with care needs.

CLINICAL IMPLICATIONS

It is essential for clinicians to be observant for unrecognized frailty and care needs in older ICs and to develop targeted intervention and prevention strategies.

Transitions in robust and prefrail octogenarians after 1 year: the influence of activities of daily living, social participation, and psychological resilience on the frailty state

BACKGROUND

Knowledge opportunities lie ahead as everyday activities, social participation, and psychological resilience might be important predictors for frailty state transitioning in the oldest old. Therefore, this article aims to examine whether changes in basic-, instrumental-, advanced- activities of daily living (b-, i-, a-ADLs), social participation, and psychological resilience predict both a transition from robustness to prefrailty or frailty and vice versa among community-dwelling octogenarians over a follow-up period of one year.

METHODS

To evaluate worsened and improved frailty transitions after one year in 322 octogenarians (Mage = 83.04 ± 2.78), the variables sex, ADLs (b-ADL-DI, i-ADL-DI, a-ADL-DI as baseline and as difference after 6 months values), the CD-RISC (Connor-Davidson Resilience Scale, as baseline and as difference after 6 months), the social participation variables (total participation score, being a member, total number of memberships, level of social participation, being a board member, volunteering, and formal participation as baseline and as difference after 6 months values), were included in a logistic regression analysis.

RESULTS

Limitations in a-ADLs at baseline (OR: 1.048, 95% confidence interval, 1.010-1.090) and an increment of limitations in a-ADLs after 6 months (OR: 1.044, 95% confidence interval, 1.007-1.085) were predictors to shift from robust to a worsened frailty state after one year follow-up. Additionally, being a woman (OR: 3.682, 95% confidence interval, 1.379-10.139) and social participation, specifically becoming a board member in 6 months (OR: 4.343, 95% confidence interval, 1.082-16.347), were protectors of robustness and thus related to an improved frailty transition after one year.

CONCLUSIONS

Encouraging healthy lifestyle behaviors to help the maintenance of ADLs, possibly leading to more social participation, could be promising in the prevention of frailty.

Hearing aid use and gender differences in the auditory-cognitive cascade in the oldest old

OBJECTIVES

This study analyzed cognitive differences between hearing-aid (HA) and non-HA users. We hypothesized that HA-use attenuates the auditory-cognitive cascade, thereby, the latter is more conspicuous in non-HA users. Since hearing impairment (HI) shows male predominance, we hypothesized gender differences within the auditory-cognitive relationship.

METHODS

Non-frail community-dwellers ≥ 80 years were assessed for HI (pure tone audiogram-PTA; speech reception threshold-SRT) and global and domain-specific cognitive impairments (Mini-Mental State Examination-MMSE; Montreal Cognitive Assessment-MOCA; Reaction Time Test-RT1-4). Pearson and partial correlations (correcting for age and PTA) assessed auditory-cognitive associations within gender and HA subgroups. Fisher's z test compared correlations between HA and non-HA users.

RESULTS

126 participants (age range 80-91 years) were included. HA-use prevalence was 21%. HA-users were older with worse HI (mean PTA 49.5dBHL). HA-users exhibited no significant auditory (PTA, SRT) and cognitive (MMSE, MOCA, RT1- RT4) correlations. Male non-HA users, displayed a significant association between HI and global cognition, processing speed, selective and alternating attention. Significant differences were noted between MMSE and PTA and SRT (z-score 2.28, 3.33, p = 0.02, <0.01, respectively) between HA and non-HA users.

CONCLUSION

Male non-HA users displayed an association between HI and global and domain-specific (processing speed; selective and alternating attention) cognitive decline. Associations between global cognition and HI were significantly different between HA and non-HA users. This may be partially attributable to underlying subgroups sample sizes and statistical power disparity. If larger scale longitudinal or interventional studies confirm these findings, timely HI assessment and management may be the cornerstone for delaying cognitive decline.

The impact of covid-19 lockdown on the Quality of life, meaningful activities, and frailty in community-dwelling octogenarians: A study in Belgium

OBJECTIVES

To investigate the impact of COVID-19 lockdown on quality of life (QoL), meaningful daily activities, and (pre)frailty in community-dwelling octogenarians.

METHODS

Cross-sectional design with bivariate and multiple linear regression modeling using a stepwise approach examining the level of QoL during the COVID-19 lockdown in a group of 215 community-dwelling octogenarians (M_age = 86.49 ± 3.02). A comprehensive set of biopsychosocial variables (FRAIL scale, general health, engagement in meaningful activities survey, questions on loneliness, and feelings) were used as explaining variables.

RESULTS

Particularly, a decrease in daily activities, social activities, and an increase in free times activities were observed, but the decrease in QoL could be explained by the meaningfulness in activities, together with experiencing emptiness in life, taking ≥ 4 medications a day and feeling down or depressed.

CONCLUSIONS

We tried to understand which components contribute to and might affect a person's QoL caused by restrictions imposed by the governance and its influence on the lives of the community-dwelling octogenarians. As such, this output could be a baseline for the development of minimally impacting countermeasures during future lockdowns.

CLINICAL IMPLICATIONS

Studying lifestyle changes and thus also variables related to QoL during a pandemic, may support policymakers and practitioners to develop relevant interventions.

Giving voice to informal caregivers of community-dwelling older adults: A systematic review of empowerment interventions

Taking care for older adults can place informal caregivers at risk for developing health problems. Therefore, interventions aiming to empower informal caregivers have been developed. Empowerment refers to a health promotion process including strategies to improve informal caregivers' self-care behaviours, stress-management and caregiving skills. In literature, empowerment-oriented interventions often target subsamples of informal caregivers defined through the care receiver's condition. These interventions, however, do not adequately capture the complexity of care needs and might even exclude informal caregivers taking care for older people without a specific diagnosis or with a subthreshold condition. Therefore, the aim of this systematic review is to provide an overview of the content and effectiveness of empowerment-oriented interventions directed at informal caregivers of community-dwelling older adults. Following the PRISMA guidelines, a systematic review was performed by searching the following databases: PubMed, PsycINFO, EMBASE and Web of Science. From a total of 6798 unique publications, 13 intervention studies, of which seven randomised controlled trials, were eligible for inclusion. According to the Mixed Methods Appraisal Tool, eight studies scored poor. The intervention studies under review represented different domains of empowerment, with cultivation of positive feelings being the most prevalent one. Social participation and physical health received little attention in interventions. Although no adverse intervention effects were observed, the studies reported mixed results with 57 positive and 47 neutral effects. The limited number and poor quality of studies emphasise the need for future research investigating the effectiveness of empowerment-oriented interventions targeting informal caregivers of older adults.

Influencing factors on instrumental activities of daily living functioning in people with mild cognitive disorder - a secondary investigation of cross-sectional data

BACKGROUND

Finding a strategy to reduce the impact of cognitive decline on everyday functioning in persons suffering from cognitive impairment is a public health priority. Instrumental activities of daily living (IADL) are key to everyday functioning. Hence, it is essential to understand the influencing factors on IADL to develop specific interventions to improve everyday functioning in persons with mild cognitive disorder. Therefore, this study aimed to 1) explore different influencing factors on IADL functioning considering all domains of the International Classification of Functioning, disability, and health and 2) rank these factors.

METHODS

We performed a secondary analysis of a cohort including participants with amnestic mild cognitive impairment (a-MCI) or mild Alzheimer's Dementia (mild AD). The IADL functioning model was used as a starting point to estimate the effects of cognitive and physical function factors and personal and environmental factors on IADL functioning using multiple linear regression analysis, including subgroup analysis in persons with a-MCI. We used standardized coefficient estimates to relate the size of the predictor effects in the final model.

RESULTS

We included 105 participants (64 a-MCI, 41 mild AD); the mean age was 81.9 years (SD 4.9), with 70% females. Based on a multi-step approach and model fit, the final model included IADL functioning as the response variable and memory, attention, executive function, vision and hearing, mobility, balance, education, and social support as predictors. The final model explained 75% of the variability. The significant predictors in the model were mobility, balance, attention, and education, and were the predictors with the most considerable effects based on standardized coefficient estimates. The subgroup analysis, including only a-MCI participants, revealed a similar pattern.

CONCLUSION

Our results confirm that IADL functioning in people with mild cognitive disorder is influenced by cognitive and physical function and personal factors. The study provides further insight into understanding IADL functioning impairments in persons with mild impaired cognition and may be used to develop specific non-pharmacological interventions.

Determinants of technology adoption and continued use among cognitively impaired older adults: a qualitative study

Background

Technology offers opportunities to support older adults with mild cognitive impairments to remain independent and socially connected, but is often not used. Although determinants of technology use among older adults in general are well studied, much less is known about how these factors impact technology use behaviour in cognitively impaired older adults. This study aimed to bridge this gap in research by examining the factors underlying technology use in community-dwelling older adults with mild cognitive impairments.

Methods

We applied a generic qualitative design and used 16 semi-structured interviews to collect data from Belgian (Flemish) community-dwelling older adults diagnosed with Mild Cognitive Impairment or dementia and informal caregivers. To get data from different perspectives, a focus group with professional caregivers was added. We used thematic analysis with an inductive approach to identify and select themes from the data.

Results

We identified two themes: introduction of technology and determinants of technology adoption and continued use. Successful technology adoption in cognitively impaired older adults is need-driven and subject to individual, technological and contextual characteristics. Specific for older adults with cognitive impairments are the importance of disease awareness and cognitive ability for adoption and continued use, respectively. Although social support can be a valuable alternative to technology, it is an important facilitator of continued technology use in these older adults. Similarly, integration of technologies in daily routines can buffer discontinuation of technologies.

Conclusions

Future research is encouraged to validate our findings in a postpandemic era and to further develop a novel theoretical framework for technology acceptance among older adults with cognitive impairments. Moreover, identification of crucial determinants as well as strategies to remove use barriers are also important future research tasks. Clinical practice should focus on improving disease awareness to facilitate technology adoption and policies should invest in training and support of professional caregivers and in reimbursement strategies to facilitate implementation of technology in practice.

Internet use and cognitive frailty in older adults: a large-scale multidimensional approach

Although research on sociodemographic correlates of internet use in older adults without and with pronounced cognitive impairment is already quite extensive, much less is known about the relationship between cognitive frailty (CF) and this behaviour. As CF is associated to multidimensional frailty aspects, this study explored the relationship between internet use and CF, operationalised as Subjective Cognitive Impairment, in older adults by means of a comprehensive explanatory model including sociodemographic factors and multiple frailty measures. The dataset included a sample of community-dwelling 60 + older adults that were included in the Belgian Ageing Studies (BAS) and that completed survey questions on (i) internet use frequency and (ii) internet activities. Multidimensional frailty was measured with the CFAI-Plus. The analysis comprised a structural equation modelling (SEM) procedure. Internet use was frequent; however, it became less frequent with higher CF. Moreover, the latter used less tablets as compared to the no-low CF group. Navigating the web, sharing email and online banking were the most frequently reported activities. Tele-communicating with Skype, online shopping and using e-government services were the least frequent. Age, female gender, lower income and living with a partner were also negatively associated with internet use. To conclude, CF, along with other frailty and sociodemographic factors, was negatively related to internet use in older adults. Future research should focus, amongst others, on the dynamic processes underlying internet use in the population of older adults affected by CF.

Perceptions of and needs for e-Health solutions for elderly people with cognitive impairment, their caregivers and health care providers: A qualitative exploration

BACKGROUND

The prevalence of mild cognitive impairment (MCI) and mild neurocognitive disorder (mNCD) are steadily increasing in Canada. Information and communication technologies (ICTs) in health represent an innovation to promote home care and autonomy for people with various degrees of cognitive impairment. The objective of this study is to develop a web-based multicriteria decision support tool adapted to older adults with MCI or mNCD, their informal caregivers, and health care providers (HCPs) to support the development and implementation of ICTs adapted to the needs and preferences of people with cognitive impairments and their caregivers.

METHODS

We used a participatory research strategy to develop of a decision support tool for the use of ICTs focused on the needs of patients, their caregivers, and HCPs. Data collection consisted of semi-structured interviews with elderly people with MCI (N = 10) and caregivers of people with mNCD (N= 7) to explore their current knowledge and perceptions of various ICTs as well as their needs and preferences for such interventions and a focus group with HCPs to understand their perceptions of the needs of seniors with MCI and caregivers of people with mNCD.

RESULTS

ICTs are seen as a beneficial solution to promote home care and autonomy for people with cognitive disorders. ICTs provide a sense of security and peace of mind, especially for caregivers of people with mNCD. However, the complexity and high cost of ICTs as well as the lack of support appear to be major limits to their use. HCP recognize the value of e-Health but claim to lack reliable information and were therefore highly unsure to recommend its use.

CONCLUSIONS

People suffering from cognitive disorders and their caregivers are generally open to technological developments and favour the use of ICTs. For health professionals, continuous training on ICTs would make them more comfortable to recommend them to patients and their families. Although the use of ICTs is promising for maintaining elderly people with cognitive disorders at home, our study shows that it will be necessary to find ways to make them accessible to promote their use.

Technology implementation in care practices for community-dwelling older adults with mild cognitive decline: Perspectives of professional caregivers in Quebec and Brussels

OBJECTIVE

As worldwide population aging is accelerating, innovative technologies are being developed to support independent living among community-dwelling older adults with mild cognitive decline. However, the successful implementation of these interventions is often challenging. Until now, literature on implementation issues related to the specific context of older adults with mild cognitive decline is lacking and the few studies available do not focus specifically on the perspective of professional caregivers. Yet the perspective of these caregivers is important as they can be considered a key facilitator for technology implementation among this population. Therefore, this study was the first to examine technology implementation among community-dwelling older adults with mild cognitive decline from the broader perspective of professional caregivers.

METHODS

In this qualitative study, two focus groups consisting of a heterogeneous pool of professional caregivers were conducted: one in Quebec (Canada, n = 6) and one in Brussels (Belgium, n = 8). Braun and Clarke' method for thematic analysis, guided by a qualitative descriptive approach was applied to inductively identify themes from the data.

RESULTS

We identified factors influencing technology implementation in older adults with mild cognitive decline on three levels: an individual level (e.g., characteristics of older adults with mild cognitive decline and professional caregivers' attitude), an organizational level (e.g., lack of training among professional caregivers) and a level referring to the broader context (e.g., ethical considerations).

CONCLUSIONS

This study contributes to the research gap in knowledge on the needs of professional caregivers to facilitate technology implementation among the population of older adults with cognitive decline. Future directions for research, practice, and policy are given, more specifically to improve knowledge among caregivers and on the development of decision support to retrieve safe and effective technologies that suit patient-centered care.

The Usefulness of Evaluating Performance of Activities in Daily Living in the Diagnosis of Mild Cognitive Disorders

The Assessment of Activities of Daily Living (ADL) is paramount to ensure the accurate early diagnosis of neurocognitive disorders. Unfortunately, the most common ADL tools are limited in their use in a diagnostic process. Hence, we set out to validate a tool to evaluate basic (b-), instrumental (i-), and advanced (a-) ADL called the Brussels Integrated Activities of Daily Living Inventory (BIA). At the geriatric day hospital of the University Hospital Brussels (Belgium) older persons (65+) labelled as Cognitively Healthy Persons (CHP) (n = 47), having a Mild Cognitive Impairment (MCI) (n = 39), and having Alzheimer's disease (AD) (n = 44) underwent a diagnostic procedure for neurocognitive disorders. Additionally, the BIA was carried out. An exploration using both (cumulative) logistic regressions and conditional inference trees aimed to select the most informative scales to discriminate between the HCP, persons with MCI and AD. The distinction between CHP and MCI and between MCI and AD was moderately successful with the i-ADLs, in addition to age. Therefore, it is advisable to conduct a multidomain assessment in which the i-ADL could serve as non-invasive and non-time-consuming screening, while the BIA might be useful for diagnostics and disease management.

Does psychological resilience mediate the relation between daily functioning and prefrailty status?

OBJECTIVES

Understanding of prefrailty's relationship with limitations in activities of daily living (ADLs) moderated by psychological resilience is needed, as resilience might support ADLs' maintenance and thus protect against frailty. Therefore, this study aims to analyze the influence of psychological resilience (using the Connor-Davidson Resilience Scale; CD-RISC) on the relation between ADLs and frailty status of older individuals (i.e. prefrail versus robust).

DESIGN

Cross-sectional design.

SETTING

UZ Brussels, Belgium.

PARTICIPANTS

Robust (Fried 0/4;n = 214; Age = 82.3 ± 2.1yrs) and prefrail (Fried 1-2/4; n = 191; Age = 83.8 ±3.2yrs) community-dwelling older individuals were included.

MEASUREMENTS

Frailty scores were obtained from weight loss, exhaustion, gait speed, and grip strength. A total Disability Index (DI) expressed dependency for basic (b-), instrumental (i-), and advanced (a-)ADLs. Mediation was investigated by estimating direct and indirect effects of all levels of ADLs and CD-RISC total score on prefrailty/robustness using a stepwise multiple regression approach.

RESULTS

Prefrailty/robustness significantly correlated with a-ADL-DI (point-biserial correlation (rpb) = 0.098; p<0.05). Adjusted for age and gender, the a-ADL-DI (p<0.05) had a significant protective direct effect against prefrailty. No effects were found with the CD-RISC total score.

CONCLUSIONS

Less limitation in a-ADLs is a directly correlated factor of prefrailty and might represent a higher likelihood of robustness.

The Effectiveness of e-Health Solutions for Aging With Cognitive Impairment: A Systematic Review

Background and Objectives

e-Health solutions are an innovative approach to support aging with cognitive impairment. Because technology is developing at a fast pace, the aim of this review was to present an overview of the research regarding the effectiveness of these solutions. Moreover, the availability of these solutions was examined.

Research Design and Methods

Systematic searches were conducted in 7 databases. Full texts of potentially relevant references were assessed by 2 reviewers, and discrepancies were solved through discussion. Data on study characteristics, technology type, application domain, availability, outcomes, and effects were extracted. A categorization exercise and narrative synthesis were conducted.

Results

In total, 72 studies describing 70 e-Health solutions were identified. The majority of solutions comprised cognitive training for older adults, followed by educational and supportive web platforms for caregivers. Outcomes included mainly measures of cognition, psychosocial functioning, caregiving processes, caregiver–care receiver relationship, and activities of daily living. Positive effects of cognitive training technologies were observed on cognitive functioning of older adults, as well as those of supportive web platforms on behavioral and psychological symptoms of dementia and caregiver self-efficacy. The effects of these solutions on depression in both target groups were inconclusive. The methodological quality of the studies was moderate to good. However, some important limitations were observed.

Discussion and Implications

The review identified cognitive training solutions and supportive web platforms as the most effective on a limited number of outcomes. Although other solutions seem promising, further research has to overcome methodological issues. Furthermore, solutions for leisure and reminiscence and outcomes specifically related to independent living deserve more attention.

A Comprehensive Overview of Activities of Daily Living in Existing Frailty Instruments: A Systematic Literature Search

BACKGROUND AND OBJECTIVES

The relationship between frailty and disability in activities of daily living (ADLs) can be seen in different ways, with disability being-to varying degrees-a characteristic, negative outcome, or predictor of frailty. This conflation of definitions is partly a result of the different frailty tools used in research. Aiming to provide a comprehensive overview, this systematic literature search analyzed (i) if, (ii) to what extent, and (iii) how ADLs are evaluated by frailty instruments.

RESEARCH DESIGN AND METHODS

A search was performed in PubMed, Web of Knowledge, and PsycINFO to identify all frailty instruments, followed by categorization of the ADL items into basic (b-), instrumental (i-), and advanced (a-) ADLs.

RESULTS

In total, 192 articles described 217 frailty instruments, from which 52.1% contained ADL items: 45.2% b-ADLs, 35.0% i-ADLs, and 10.1% a-ADLs. The most commonly included ADL items were bathing (b-ADLs); using transportation (i-ADLs); and semiprofessional work engagement in organized social life or leisure activities (a-ADLs). These instruments all had a multidomain origin (χ 2 = 122.4, p < .001).

DISCUSSION AND IMPLICATIONS

Because 52.1% of all instruments included ADL items, the concepts of frailty and disability appear to be highly entangled. This might lead to circular reasoning, serious concerns regarding contamination, and invalid research results.

Prefrailty: The Relationship Between Daily Activities and Social Participation in Older Persons

OBJECTIVES

To analyze prefrailty's relationship with limitations in activities of daily living (ADLs) and restrictions in social participation.

METHOD

Robust (Fried 0/4; n = 214; M_age = 82.3 years [SD ±2.1]) and prefrail (Fried 1-2/4; n = 191; M_age = 83.8 years [SD ±3.2]) community-dwelling older individuals were included. Frailty scores were obtained from weight loss, exhaustion, gait speed, and grip strength. A total disability index (DI) expressed dependency for basic (b-), instrumental (i-), and advanced (a-)ADLs. Total participation score, being a member, total number of memberships, being a board member, level of participation, membership over time, volunteering, and formal participation represented social participation.

RESULTS

Logistic regression retained age (OR = 1.224; 95% CI = [1.122, 1.335]), sex (OR = 3.818; 95% CI = [2.437, 5.982]), and a-ADL-DI (OR = 1.230; 95% CI = [1.018, 1.486]) as variables significantly related to prefrailty (68.3%; χ² = 68.25; df = 3; p < .001).

DISCUSSION

Subtle limitations in a-ADLs, higher age, and being a man were associated with prefrailty, revealing the possible role of personal and culturally related a-ADLs as red flags for (pre)frailty.

Prevalence of mild cognitive problems in Flemish Nursing homes

Background

Mild cognitive decline in Nursing Home (NH) residents without dementia is often noted very late since cognitive demands are relatively low in this setting. Therefore, subtle cognitive changes could remain undetected. This study aimed to evaluate the prevalence of mild cognitive problems in NHs.

Methods

First, a file study was performed to exclude residents with a diagnosis of dementia or known cognitive problems (Mini Mental State Examination-MMSE &lt; 24) in 16 NHs. Second, remaining residents were screened for cognition with the Montreal Cognitive Assessment (MoCA). Also, an evaluation of functionality (ADL-Questionnaire), mood (Geriatric Depression Scale), neuropsychiatric symptoms (Neuropsychiatric Inventory Questionnaire) and subjective memory complaints (Informant Questionnaire on Cognitive Decline) was performed.

Results

On a total of 1339 residents, 229 persons (17.1%) had no diagnosis of dementia and an MMSE &gt;23. Based on MoCA-cut-offs 2.7% (n = 36), 11.4% (n = 152) and 3.1% (n = 41) could be labelled as cognitively normal (&gt;25), mild cognitive impairment (&gt;16 and &lt;26) and mild dementia (&lt;17) respectively. This resulted in a prevalence of undetected mild cognitive problems of 14.5% (n = 193) in the total NH population. Significant differences between the 3 groups were found for functionality, mood, neuropsychiatric symptoms and subjective memory complaints (all p &lt; 0.05).

Conclusions

Considering their advanced age NH residents are vulnerable to develop dementia. This study showed that an important part of them has unnoticed mild cognitive problems. NHs should be aware of this risk group in order to provide adequate prevention and support.

e-Health interventions for healthy aging: a systematic review

BACKGROUND

Healthy aging (HA) is a contemporary challenge for population health worldwide. Electronic health (e-Health) interventions have the potential to support empowerment and education of adults aged 50 and over.

OBJECTIVES

To summarize evidence on the effectiveness of e-Health interventions on HA and explore how specific e-Health interventions and their characteristics effectively impact HA.

METHODS

A systematic review was conducted based on the Cochrane Collaboration methods including any experimental study design published in French, Dutch, Spanish, and English from 2000 to 2018.

RESULTS

Fourteen studies comparing various e-Health interventions to multiple components controls were included. The target population, type of interventions, and outcomes measured were very heterogeneous across studies; thus, a meta-analysis was not possible. However, effect estimates indicate that e-Health interventions could improve physical activity. Positive effects were also found for other healthy behaviors (e.g., healthy eating), psychological outcomes (e.g., memory), and clinical parameters (e.g., blood pressure). Given the low certainty of the evidence related to most outcomes, these results should be interpreted cautiously.

CONCLUSIONS

This systematic review found limited evidence supporting the effectiveness of e-Health interventions, although the majority of studies show positive effects of these interventions for improving physical activity in older adults. Thus, better quality evidence is needed regarding the effects of e-Health on the physiological, psychological, and social dimensions of HA.

SYSTEMATIC REVIEW REGISTRATION

The review protocol was registered in PROSPERO (registration number: CRD42016033163).

The relationship between quality of life in a nursing home and personal, organizational, activity-related factors and social satisfaction: a cross-sectional study with multiple linear regression analyses

Objectives: This study aimed to investigate quality of life in nursing home residents and the relationship with personal, organizational, activity-related factors and social satisfaction.Methods: In a cross-sectional survey study in 73 nursing homes in Flanders, Belgium, 171 cognitively healthy residents were randomly recruited (mean age 85.40 years [±5.88]; 27% men, 73% women). Quality of life, as the dependent/response variable, was measured using anamnestic comparative self-assessment (range -5 to +5). Multiple linear regression (forward stepwise selection) was used (1) to investigate which factors were significantly related to nursing home residents' quality of life and (2) to model the relationship between the variables by fitting a linear equation to the observed data.Results: Nursing home residents reported a quality of life score of 2.12 (±2.16). Mood, self-perceived health status, social satisfaction and educational level were withheld as significant predictors of the anamnestic comparative self-assessment score (p < 0.001), explaining 38.1% of the variance in quality of life.Conclusions: Results suggest that a higher quality of life in nursing homes can be pursued by strategies to prevent depression and to improve nursing home residents' subjective perception of health (e.g. offering good care) and social network. It is recommended that nursing homes prepare for future generations, who will be more educated.

The relationship between basic, instrumental, and advanced activities of daily living and executive functioning in geriatric patients with neurocognitive disorders

OBJECTIVE

Although many studies explored the relationship between executive functions (EF) and activities of daily living (ADLs) in cognitive disorders, previous studies used measurements without well-defined levels of ADLs. This study explored the relationship between EF and the threefold classification of everyday functioning (basic or b-, instrumental or i-, and advanced or a-ADLs) and examined how EF account for the variance in this triad of everyday functioning.

METHODS

A sample of 44 cognitively healthy persons, 41 persons with mild cognitive impairment, and 35 persons with Alzheimer disease were assessed with comprehensive measures of EF and the b-, i-, and a-ADL tools.

RESULTS

Correlations demonstrated that subjects with higher executive dysfunctions have more limitations in b-, i-, and a-ADLs. The highest significant correlations with measures of EF were seen in i- and a-ADLs (ranging from r = -0.193 to r = -0.559, P < 0.05). However, correlations with a-ADLs were not stronger than with i-ADLs. The multivariate analyses revealed Trail Making Test A (TMT-A) as a significant contributor of everyday functioning in b-ADLs, as well as i- and a-ADLs, and Clock Drawing Test (CDT) and Animal Fluency Test (AFT) seemed to contribute significantly to variance in i- and a-ADLs.

CONCLUSIONS

EF are less related to b-ADLs than i- and a-ADLs and contribute to the same amount of variance to limitations in both i- and a-ADLs. This study recommends using the TMT-A, CDT, and AFT as screening tools to indicate the need for profound evaluation of ADLs in older persons with neurocognitive disorders.

Application of participation in clinical practice: Key issues

BACKGROUND

Rehabilitation services are increasingly targeting involvement in daily life. In the International Classification of Functioning, Disability and Health this is referred to as "participation". How-ever, questions have arisen regarding the conceptualization of participation, and consensus is lacking.

METHODS

The first phase of this study is a critical review of the literature to detect recurring conceptual problems in the application of participation and how researchers deal with these. The second phase is a systematic review to identify how participation measures are operationalized.

RESULTS

The critical review found possible solutions to 4 recurring key limitations: (i) how to deal with ambiguity and vagueness regarding the term "participation"; (ii) how to differentiate between activity and participation; (iii) what is the current empirical knowledge about the subjective aspects of participation; (iv) what are the different ways to measure participation. The systematic review found 18 instruments operationalizing participation in different ways: (i) unidimensional: frequency of performing activities; (ii) unidimensional: limitations in experiencing participation when performing activities; (iii) multidimensional: multiple subjective dimensions when performing activities; and (iv) multidimensional: objective and subjective dimensions.

DISCUSSION AND CONCLUSION

Notwithstanding an increasing body of knowledge, some issues remain unclear and how participation is measured is subject to debate. This results in difficulties in the use of participation in clinical practice. However, insight into the current body of knowledge and awareness of shortcomings might help clinicians who aim to apply participation in practice.

Increasing use of cognitive measures in the operational definition of frailty-A systematic review

Ageing is associated both with frailty and cognitive decline. The quest for a unifying approach has led to a new concept: cognitive frailty. This systematic review explores the contribution of cognitive assessment in frailty operationalization. PubMed, Web of Knowledge and PsycINFO were searched until December 2016 using the keywords aged; frail elderly; aged, 80 and over; frailty; diagnosis; risk assessment and classification, yielding 2863 hits. Seventy-nine articles were included, describing 94 frailty instruments. Two instruments were not sufficiently specified and excluded. 46% of the identified frailty instruments included cognition. Of these, 85% were published after 2010, with a significant difference for publication date (X² = 8.45, p < .05), indicating increasing awareness of the contribution of cognitive deficits to functional decline. This review identified 7 methods of cognitive assessment: dementia as co-morbidity; objective cognitive-screening instruments; self-reported; specific signs and symptoms; delirium/clouding of consciousness; non-specific cognitive terms and mixed assessments. Although cognitive assessment has been increasingly integrated in recently published frailty instruments, this has been heterogeneously operationalized. Once the domains most strongly linked to functional decline will have been identified and operationalized, this will be the groundwork for the identification of reversible components, and for the development of preventive interventional strategies.

A retrospective study of a multicomponent rehabilitation programme for community-dwelling persons with dementia and their caregivers

Introduction

This study determined whether the multicomponent rehabilitation programme of a memory clinic had positive outcomes on ameliorating everyday functioning, quality of life, mood and behavioural disturbances of persons with dementia and reducing distress and burden of caregivers.

Method

A retrospective pre-test–post-test study without control group was conducted on the first cohort of persons with dementia ( n = 30) and their caregivers ( n = 30), who participated in a programme lasting for a maximum of 1 year with 25 1-hour counselling sessions. The assessment contained an evaluation of everyday functioning in basic, instrumental and advanced activities of daily living, cognition, mood, emotional and behavioural disturbances, quality of life and caregiver burden.

Results

Eight participants dropped out prematurely. For persons with dementia ( n = 22), participating in the programme did not improve everyday functioning and cognition but ameliorated quality of life significantly ( Z = –2.7, p = 0.006, 95% CI (.003–.005)) and stabilized mood, emotional and behavioural disturbances for 60% or more of them. For caregivers ( n = 22), the mild to moderate burden of care remained stable or got better for 63.6% of the caregivers.

Conclusion

This programme appears to be promising and valuable, and might reduce institutionalization rates. Future explorations are recommended to research how participants evolve and to investigate which participants responded in a positive way.

Experiences and Effects of Structurally Involving Residents in the Nursing Home by Means of Participatory Action Research: A Mixed Method Study

OBJECTIVES

This study aimed to examine the effects of introducing participatory action research (PAR) within the nursing home (NH) on residents' quality of life (QoL) and NH experience and participation, and to explore their experiences with PAR.

DESIGN

A mixed methods design was chosen, including a clustered randomized controlled trial (RCT) and qualitative interviews.

SETTING

For the RCT, 3 NHs were randomly allocated to 3 conditions: an intervention (weekly PAR activity), an active control (weekly reminiscence-activity), or passive control (care as usual). The qualitative study took place in the intervention NH.

PARTICIPANTS

Within the RCT, about 30 residents were recruited for assessments per NH, including 9 PAR participants and 10 reminiscence participants. Qualitative interviews were held with all PAR participants (residents and internal moderator).

INTERVENTION

PAR is a method to structurally involve residents in the NH operation. Weekly PAR sessions were held with 9 residents and 2 moderators. Here, residents critically analyzed and discussed the NH operation, identified possible problems, suggested improvements, which were further implemented by the NH and monitored by the PAR group.

MEASUREMENTS

Residents' NH experience (NH Active Aging Survey), QoL (Anamnestic Comparison Self-Assessment), and experienced participation (Impact on Participation and Autonomy) were measured in the RCT at pre-test, post-test (6 months), and follow-up (12 months). The qualitative study took into account interviews with the PAR stakeholders after 6 months.

RESULTS

The RCT showed residents' QoL improving more between pre-test and follow-up in the intervention and active control NH compared with the passive control NH. No other effects were observed. The qualitative data revealed a positive PAR experience. Participants enjoyed the activity and indicated various positive influences. Still, there was room for improvement, including communication toward other residents and between staff.

CONCLUSIONS

Notwithstanding the modest quantitative effects, PAR led to positive experiences and can have a future in the NH when solving some limitations.

Linking Frailty Instruments to the International Classification of Functioning, Disability, and Health: A Systematic Review

To date, the major dilemma concerning frailty is the lack of a standardized language regarding its operationalization. Considering the demographic challenge that the world is facing, standardization of frailty identification is indeed the first step in tackling the burdensome consequences of frailty. To demonstrate this diversity in frailty assessment, the available frailty instruments have been linked to the International Classification of Functioning, Disability, and Health (ICF): a standardized and hierarchically coded language developed by World Health Organization regarding health conditions and their positive (functioning) and negative (disability) consequences. A systematic review on frailty instruments was carried out in PubMed, Web of Knowledge, and PsycINFO. The items of the identified frailty instruments were then linked to the ICF codes. 79 original or adapted frailty instruments were identified and categorized into single (n = 25) and multidomain (n = 54) groups. Only 5 frailty instruments (indexes) were linked to all 5 ICF components. Whereas the ICF components Body Functions and Activities and Participation were frequently linked to the frailty instruments, Body Structures, Environmental and Personal factors were sparingly represented mainly in the multidomain frailty instruments. This review highlights the heterogeneity in frailty operationalization. Environmental and personal factors should be given more thought in future frailty assessments. Being unambiguous, structured, and neutral, the ICF language allows comparing observations made with different frailty instruments. In conclusion, this systematic overview and ICF translation can be a cornerstone for future standardization of frailty assessment.

Motivators and barriers for physical activity in older adults with osteoporosis

BACKGROUND AND PURPOSE

Although physical activity (PA) is an important tool to counter osteoporosis, too few older patients with osteoporosis (OPWO) engage in PA. Little is known about specific motivators for and barriers to PA in OPWO, hindering the development of targeted PA promotion campaigns for these persons. Therefore, the main objective of this study was to identify motivators for and barriers to PA specifically in OPWO.

METHODS

This qualitative study identified specific motivators for and barriers to PA in OPWO through 2 different methods: focus groups with professionals and in-depth interviews with OPWO.

RESULTS

The OPWO tended to give a broad interpretation of what they considered as PA (practicing sports, physical work, and performing household activities), whereas the professionals seemed to mainly focus on (therapeutic) exercise as PA. Fifteen different motivators and 18 barriers have been identified. Among others, health improvement, social contact, habit, feeling good, and receiving medical advice from a medical doctor were motivators. Pain, fear of falling, bad weather, lack of interest, and caring for an ill partner were barriers to PA. For some older respondents, osteoporosis acted as a trigger for PA, and for others it was a barrier.

CONCLUSIONS

This study emphasizes the importance for health care professionals to give personalized PA advice regarding the nature and frequency of PA that is safe and beneficial for osteoporosis. It stands to reason that the information about PA needs to be clear and consistent. Furthermore, it is quintessential to mention that it can take some time to adapt to physical exercise and to experience the beneficial effects, because pain sensations during the first PA sessions can be perceived as barriers to OPWO. Misconceptions or barriers to PA should be countered by assessing motivators for and barriers to PA by the health care professional together with the older client so that barriers can be eliminated and motivators can be strengthened. Physical activity education should involve not only the OPWO but also their relatives, friends, and important peers. Different social aspects of PA and the encouragements from peers are stimulating for older adults to initiate and to continue PA. The results of our study can constitute a starting point for further research to identify the motivators for and barriers to PA with the highest impact on PA behavior in OPWO, thus enabling evidence-based PA promotion campaigns for this patient group.

Active ageing within the nursing home: a study in Flanders, Belgium

Nursing homes should support residents' quality of life (QoL). It remains vague, however, how these facilities can create a QoL enhancing environment. Active ageing (AA) is a useful framework in this context, since it provides a multidimensional set of determinants that enhance QoL. This study examined the current status of AA in nursing homes in Flanders, Belgium. A sample of 383 randomly recruited residents was surveyed on the subjective importance and experienced reality of the AA determinants as well as on QoL. Based on descriptive analyses, residents appeared to have a positive QoL and a moderately positive appraisal of the extent to which nursing homes provide a multidimensional environment to enhance their QoL. Multivariate analyses showed that residents' nursing home active ageing (NHAA) experience was positively related to their QoL and explained 20 % of its variance. Specifically, psychological factors and participation related positively to QoL. Demographic variables showed no relationships with QoL, while educational level related negatively to the NHAA experience. Currently, in Flanders, nursing homes are on their way to working according to the AA vision, but further efforts are still needed.

Age-related differences in muscle recruitment and reaction-time performance

Previously, we showed that prolonged reaction-time (RT) in older persons is related to increased antagonist muscle co-activation, occurring already before movement onset. Here, we studied whether a difference in temporal agonist and antagonist muscle activation exists between young and older persons during an RT-test. We studied Mm. Biceps (antagonist muscle) & Triceps (agonist muscle) Brachii activation time by sEMG in 60 young (26 ± 3 years) and 64 older (80 ± 6 years) community-dwelling subjects during a simple point-to-point RT-test (moving a finger using standardized elbow-extension from one pushbutton to another following a visual stimulus). RT was divided in pre-movement-time (PMT, time for stimulus processing) and movement-time (MT, time for motor response completion). Muscle activation time 1) following stimulus onset (PMAT) and 2) before movement onset (MAT) was calculated. PMAT for both muscles was significantly longer for the older subjects compared to the young (258 ± 53 ms versus 224 ± 37 ms, p=0.042 for Biceps and 280 ± 70 ms versus 218 ± 43 ms for Triceps, p<0.01). Longer agonist muscle PMAT was significantly related to worse PMT and RT in young (respectively r=0.76 & r=0.68, p<0.001) and elderly (respectively r=0.42 & r=0.40, p=0.001). In the older subjects we also found that the antagonist muscle activated significantly earlier than the agonist muscle (-22 ± 55 ms, p=0.003). We conclude that in older persons, besides the previously reported increased antagonist muscle co-activation, the muscle firing sequence is also profoundly altered. This is characterized by a delayed muscle activation following stimulus onset, and a significantly earlier recruitment of the antagonist muscle before movement onset.

Diversity, dispersion and inconsistency of reaction time measures: effects of age and task complexity

BACKGROUND AND AIMS

Performance variability of reaction time is regarded as an important parameter for cognitive functioning with aging. We investigated three types of variability, diversity (or variability between persons), dispersion (variability across trials within one task) and inconsistency (variability across testing occasions), while distinguishing between decision time and movement time and evaluating performance across comparable complexity levels.

METHODS

A single stratified reaction time test based on tasks with increasing complexity was used to evaluate inter- and intra-performance variability of 27 older (age 75+/-5 years) and 27 younger (age 29+/-7 years) participants, subdividing reaction time into decision and movement components.

RESULTS

There were consistent age and complexity differences for all variability types in our sample. When controlling for processing speed, which was slower in the older group, variability across age groups and task complexity tended to diminish and a more complex picture emerged. The elderly group showed a higher diversity of all reaction time measures, except for movement time, and a higher dispersion of decision time. Task complexity significantly affected the diversity of movement and overall reaction times and the dispersion of all reaction time measures, except for movement time.

CONCLUSIONS

These results highlight the importance of variability in cognitive functioning; it may be an important phenomenon for study and a useful indicator for cognitive deterioration. The reaction time test we propose is easy to use and can be applied in clinical practice.

The advanced activities of daily living: a tool allowing the evaluation of subtle functional decline in mild cognitive impairment

OBJECTIVES

Assessment of advanced activities of daily living (a-ADL) can be of interest in establishing the diagnosis of Alzheimer's disease (AD) in an earlier stage, since these activities demand high cognitive functioning and are more responsive to subtle changes. In this study we tested a new a-ADL tool, developed according to the International Classification of Functioning, Disability and Health (ICF). The a-ADL tool is based on the total number of activities performed (TNA) by a person and takes each subject as his own reference. It distinguishes a total disability index (a-ADL-DI), a cognitive disability index (a-ADL-CDI), and a physical disability index (a-ADL-PDI), with lower score representing more independency. We explored whether these indices allow distinction between cognitively healthy persons, patients with Mild Cognitive Impairment (MCI) and patients with mild AD.

METHODS

Participants were on average 80 years old (SD 4.6; 66-90), were community dwelling, and were diagnosed as (1) cognitively healthy subjects (n=26); (2) patients with MCI (n = 17), or (3) mild AD (n = 25), based upon extensive clinical evaluation and a set of global, cognitive, mood and functional assessments. The a-ADL-tool was not part of the clinical evaluation.

RESULTS

The a-ADL-CDI was significantly different between the three groups (p<.01). The a-ADL-DI was significantly different between MCI and AD (p<.001). The tool had good psychometrical properties (inter-rater reliability; agreement between patient and proxy; correlations with cognitive tests). Although the sample size was relatively small, ROC curves were computed for the a-ADL-DI and a-ADL-CDI with satisfactory and promising results.

CONCLUSION

The a-ADL-CDI and a-ADL-DI might offer a useful contribution to the identification and follow up of patients with mild cognitive disorders in an older population.

Interventions to enhance the Quality of Life of older people in residential long-term care: a systematic review

PURPOSE

In residential long-term care (LTC), a growing interest exists in the older residents' Quality of Life (QoL). The Active Ageing-concept (AA) extended this focus, since AA has the aim to enhance QoL by optimising the opportunities for health, participation and security. In LTCs, AA can be outlined by 9 determinants. This systematic review aimed at identifying interventions to improve the QoL of LTC-residents. These interventions were organised according to the AA-determinants.

METHODS

PubMed, Web of Science, Psychinfo and Sociological Abstracts were screened systematically. Articles were excluded when they only concerned a specific group of LTC-residents.

RESULTS

Thirty five relevant articles, encompassing 3910 subjects were found. These concerned interventions concentrating on one or more of the 9 AA-determinants. The largest proportion of interventions regarded the physical activity level or the psychological factors of the residents. Overall, no systematic effects on QoL could be found and a low methodological quality was generally present.

CONCLUSION

Currently, studies aimed at enhancing the QoL of older LTC-resident are limited and often directed to physical and psychological interventions. The lack of a systematic effect on QoL is possibly related to the fact that these interventions were often not multidimensional, whereas QoL is a multidimensional concept.

The Active Ageing-concept translated to the residential long-term care

PURPOSE

Active Ageing (AA), as described by the WHO (Active Ageing: a policy framework. World Health Organisation, Geneva 5), is an important concept in gerontology. Since the AA-concept has not been examined in the context of residential long-term care facilities, our study addresses this gap by describing the determinants of AA within this setting.

METHODS

A qualitative study with semi-structured focus groups, followed by a thematic analysis, was conducted. Through purposive sampling, four focus groups of either residents of long-term care facilities (n = 8), children of residents (n = 8), community-dwelling older people (n = 8) and gerontologists (n = 6) were formed.

RESULTS

The thematic analysis yielded nine determinants of AA. Seven correspond to those identified by the WHO: Culture, Behaviour, Psychological Factors, Physical Environment, Social Environment, Economic Characteristics and Health and Social Care. Two new determinants were identified: Meaningful Leisure and Participation. The determinant Participation is seen as crucial to AA in residential care.

CONCLUSION

This study points to a more extensive set of determinants of AA than those identified by the WHO (Active Ageing: a policy framework. World Health Organisation, Geneva 5). Staff of long-term care facilities can make use of these determinants to promote AA in their residents.

The use of acetyl cholinesterase inhibitors and memantine in nursing home residents

AIM

Although a high proportion of elderly nursing home residents suffer from Alzheimer's disease (AD), data from the literature indicate that they are only rarely treated with Acetyl Cholinesterase Inhibitors (ChEls) or memantine. The aim of this study was to describe the use of ChEls or memantine by elderly residents in nursing homes, suffering from AD and to document who might qualify for pharmacological treatment according to the Belgian reimbursement rules.

METHOD

Descriptive data was collected from 11 nursing homes through a standardized questionnaire consisting of a general section for nurses and a specific medical section for general practitioners (GP). All residents (N = 1032) from these institutions were eligible for inclusion in the study; 718 (69.6%) questionnaires were completed by the nurses of which 533 (51.6%) were also completed by the GP's.

RESULTS

AD was diagnosed in 29.4% (n = 211) of the residents of whom 56.4% (n = 119) did not receive an anti-AD treatment, although nearly all of these patients fulfilled the Belgian requirements for reimbursement of ChEls or memantine. The mental status of the residents was often incompletely documented, but it can be estimated that at least an additional 30.1% (n = 216) of all screened residents might possibly qualify for reimbursement of ChEls or memantine.

CONCLUSIONS

Less than half of the AD patients in nursing homes receive ChEls or memantine and approximately one third of the residents could possibly qualify for reimbursement. Many residents with cognitive deficits remain undetected and undiagnosed and consequently do not receive appropriate treatment.

Conversion of the Mini-Mental State Examination to the International Classification of Functioning, Disability and Health terminology and scoring system

BACKGROUND

In older patients, evaluation of the cognitive status is crucial. The Mini-Mental State Examination (MMSE) is widely used for screening of cognition, providing fairly high sensitivity, specificity and reproducibility. Recently, a consensus emerged on the necessity of an international and transparent language, as provided by the WHO's International Classification of Functioning, Disability and Health (ICF). Most assessment tools however are not in accordance with the ICF.

OBJECTIVE

To reformulate the MMSE according to the ICF, both for the individual items and for the scoring system.

METHOD

MMSE data (scores varying from 3 to 30/30) of (1) 217 cognitively healthy elderly, (2) 60 persons with mild cognitive impairment, (3) 60 patients with mild Alzheimer's disease (AD), and (4) 60 patients with moderate/severe AD were obtained from studies at a university hospital setting. Subjects were aged 65 years or more and recruited either through advertisement (group 1), from the geriatric day hospital (groups 2 and 3), or the geriatric ward (group 4). The allocation to the groups was done after multidisciplinary evaluation. The conversion of the MMSE to ICF-MMSE was done by content comparison and by subsequent translation of the scoring system using automatic algorithms.

RESULTS

All MMSE items were converted to the corresponding ICF categories. Three ICF domains were addressed: global and specific mental functions, general tasks and demands, divided over 6 ICF categories (orientation time/place, sustaining attention, memory functions, mental functions of language, undertaking a simple task). Scores on individual items were transformed according to their relative weight on the original MMSE scale, and a total ICF-MMSE score from 0 (no problem) to 100 (complete problem) was generated. Translation was satisfying, as illustrated by a good correlation between MMSE and ICF-MMSE. The diagnostic groups were distributed over the ICF-MMSE scores as expected. For each ICF domain, ICF-MMSE subscores were higher with increasing severity in cognitive decline. There was a higher dispersion, in accordance with the more detailed scoring possibilities of the ICF-MMSE.

CONCLUSIONS

It is possible to adapt the MMSE to the ICF concept. This adaptation enhances interdisciplinary communication since it provides more clarity in assessment, with better visibility of the areas covered by the instrument.

Motivators and barriers for physical activity in the oldest old: a systematic review

Worldwide, people engage insufficiently in physical activity, particularly subjects aged 80 years and over. For optimal life-style campaigns, knowledge of motivators and barriers for physical activity is mandatory. Given their specific needs, it is conceivable that these would be different for the oldest old compared to younger subjects. Pubmed, Web of Science and Psychinfo were systematically screened for articles reporting motivators and barriers for physical activity. Papers were excluded if data regarding elderly aged >79 years were absent. Forty-four relevant articles were included, involving a total of 28,583 subjects. Sixty one motivators and 59 barriers for physical activity in the elderly were identified, including those who are relevant for persons aged 80 years and over. Based on the results of our literature review, we recommend that when promoting physical activity in the oldest old, special attention is paid to the health benefits of physical activity, to the subject's fears, individual preferences and social support, and to constraints related to the physical environment. However, no studies were found exclusively describing people aged 80 years and over, and future research is necessary to differentiate the barriers or motivators that are specific for the oldest old from those of younger elderly.

Age-related differences in pre-movement antagonist muscle co-activation and reaction-time performance

Multiple causes contribute to the prolonged reaction-times (RT) observed in elderly persons. The involvement of antagonist muscle co-activation remains unclear. Here the Mm. Biceps and Triceps Brachii activation in 64 apparently healthy elderly (80 ± 6 years) and 60 young (26 ± 3 years) subjects were studied during a simple RT-test (moving a finger using standardized elbow-extension from one pushbutton to another following a visual stimulus). RT was divided in pre-movement-time (PMT, time for stimulus processing) and movement-time (MT, time for motor response completion). RT-performance was significantly worse in elderly compared to young; the slowing was more pronounced for MT than PMT (respectively 101 ± 10 ms and 41 ± 6 ms slower, p<0.01). Elderly subjects showed significantly higher (p<0.01) antagonist muscle co-activation during the PMT-phase, which was significantly related to worse MT and RT (p<0.01). During the MT-phase, antagonist muscle co-activation was similar for both groups. It can be concluded that increased antagonist muscle co-activation in elderly persons occurs in an early phase, already before the start of the movement. These findings provide further understanding of the underlying mechanisms of age-related slowing of human motor performance.

Reaction times and performance variability in normal aging, mild cognitive impairment, and Alzheimer's disease

This study evaluated whether reaction times (RT) and performance variability are potential markers for the early detection of Alzheimer's disease (AD). Cognitively healthy elderly (n = 218), persons with amnestic MCI (a-MCI) (n = 29) and patients with AD (n = 50) were examined with RT tasks with increasing complexity, subdividing RT into a decision and a movement component. Persons with cognitive deterioration demonstrated more intra-individual variability and more slowing than cognitively healthy elderly. The slowing in AD affects both the cognitive and the motor component, while performance variability mainly affects the cognitive component of the RT. Although in a-MCI not all differences reached statistical significance, primarily the cognitive component of the RT is affected in a-MCI. Intra-individual variability and RT of the complex tasks are the best predictors for a-MCI and AD status, respectively. We conclude that performance variability can be regarded as a useful preclinical marker for AD.

The influence of galantamine on reaction time, attention processes, and performance variability in elderly Alzheimer patients

OBJECTIVE

To examine the effect of galantamine in elderly patients with mild to moderate Alzheimer disease (AD) on reaction time (RT), selective (SA) and alternating attention (AA), errors, and on interindividual and intraindividual variability.

METHODS

Forty-one outpatients with AD were included in an open-label prospective trial and evaluated at baseline and after 8 and 22 weeks of treatment using a RT test that allows differentiation between the decision and movement time components of the total RT. The various tasks of the RT test allowed calculation of SA and AA. Standard AD evaluation tests were performed at baseline and after 22 weeks.

RESULTS

After 8 and 22 weeks of treatment, an improvement of decision time and RT at all complexity levels was noted. For movement time, improvements were less pronounced and not present at both follow-up moments or at all complexity levels. Selective attention, but not AA, improved significantly after 22 weeks. A decrease in the number of errors was noted. At several complexity levels, both at 8 and 22 weeks, the interindividual and intraindividual variability decreased. Changes in Mini Mental State Evaluation score were correlated with those in SA.

CONCLUSIONS

Our study provides arguments that galantamine treatment improves various parameters of the RT, attention, and interindividual and intraindividual variability in elderly AD patients. Because the study is not a controlled trial, further investigation is needed.

Handgrip performance in relation to self-perceived fatigue, physical functioning and circulating IL-6 in elderly persons without inflammation

Background

Low grip strength is recognized as one of the characteristics of frailty, as are systemic inflammation and the sensation of fatigue. Contrary to maximal grip strength, the physical resistance of the muscles to fatigue is not often included in the clinical evaluation of elderly patients. The aim of this study was to investigate if the grip strength and the resistance of the handgrip muscles to fatigue are related to self-perceived fatigue, physical functioning and circulating IL-6 in independently living elderly persons.

Methods

Forty elderly subjects (15 female and 25 male, mean age 75 ± 5 years) were assessed for maximal grip strength, as well as for fatigue resistance and grip work (respectively time and work delivered until grip strength drops to 50% of its maximum during sustained contraction), self perceived fatigue (VAS-Fatigue, Mob-Tiredness scale and the energy & fatigue items of the WHOQOL-100), self rated physical functioning (domain of physical functioning on the MOS short-form) and circulating IL-6. Relationships between handgrip performance and the other outcome measures were assessed.

Results

In the male participants, fatigue resistance was negatively related to actual sensation of fatigue (VAS-F, p < .05) and positively to circulating IL-6 (p < .05). When corrected for body weight, the relations of fatigue resistance with self-perceived fatigue became stronger and also apparent in the female. Grip strength and grip work were significantly related with several items of self-perceived fatigue and with physical functioning. These relations became more visible by means of higher correlation coefficients when grip strength and grip work were corrected for body weight.

Conclusion

Well functioning elderly subjects presenting less handmuscle fatigue resistance and weaker grip strength are more fatigued, experience more tiredness during daily activities and are more bothered by fatigue sensations. Body weight seems to play an important role in the relation of muscle performance to fatigue perception. Elderly patients complaining from fatigue should be physically assessed, both evaluating maximal grip strength and fatigue resistance, allowing the calculation of grip work, which integrates both parameters. Grip work might best reflect the functional capacity resulting from the development of a certain strength level in relation to the time it can be maintained.

Attentional processes discriminate between patients with mild Alzheimer's disease and cognitively healthy elderly

BACKGROUND

It is generally accepted that Alzheimer's disease (AD) is mainly characterized by memory disorders. Although recent studies also point to an important role of attention deficits early in the disease, this notion has not yet emerged in clinical practice. Our aim was to assess whether attention, quantified by reaction times, can discriminate between patients with mild AD and controls and therefore contribute to clinical diagnosis.

METHODS

In a cross-sectional study, 33 patients with mild AD were matched with cognitively healthy elderly controls for age, gender, educational level and depressive mood. Selective attention (SA), alternating attention (AA) and error-rates were measured by a modified reaction time test.

RESULTS

Significant differences between both groups were found for all measures. Logistic regression showed that SA (corrected for individual processing speed) and error-rates could correctly classify subjects with an overall hit ratio of 81%. When attention measures were not corrected for individual processing speed, the overall hit ratio improved to 97%.

CONCLUSION

SA and AA deteriorate in patients with mild AD and these measures can be used to discriminate between patients and matched controls, independently of depressive mood.
