Research shows that mental demands at work affect later-life cognitive functioning and dementia risk, but systematic assessment of protective mental work demands (PMWDs) is still missing. The goal of this research was to develop a questionnaire to assess PMWDs.

The instrument was developed in accordance with internationally recognized scientific standards comprising conceptualization, pretesting, and validation via confirmatory factor analysis (CFA), principal component analysis (PCA), and multiple regression analyses.

We included 346 participants, 72.3% female, with an average age of 56.3 years.

Item pool, sociodemographic questions, and cognitive tests: Trail-Making Test A/B, Word List Recall, Verbal Fluency Test, Benton Visual Retention Test, Reading Minds in the Eyes Test.

CFAs of eight existing PMWD-concepts revealed weaker fit indices than PCA of the item pool that resulted in five concepts. We computed multivariate regression analyses with all 13 PMWD-concepts as predictors of cognitive functioning. After removing PMWD-concepts that predicted less than two cognitive test scores and excluding others due to overlapping items, the final questionnaire contained four PMWD-concepts: Mental Workload (three items, Cronbach’s α = .58), Verbal Demands (four, Cronbach’s α = .74), Information Load (six, Cronbach’s α = .83), and Extended Job Control (six, Cronbach’s α = .83).

The PMWD-Questionnaire intends to assess protective mental demands at the workplace. Information processing demands and job control make up the primary components emphasizing their relevance regarding cognitive health in old age. Long-term follow-up studies will need to validate construct validity with respect to dementia risk.

To examine whether the educational level moderates the relationship between baseline depressive symptoms and cognitive functioning at 5- and 10-year follow-ups in older adults, considering the association between cognitive functioning and difficulty with activities of daily living (ADL).

Using a prospective design, a path analysis was performed.

In-home, face-to-face interviews and self-administered questionnaires, within the National Social Life, Health, and Aging Project.

In total, 1,461 participants (mean age = 66.62) were followed up from Wave 1 (baseline) to Wave 2 (at 5 years) and Wave 3 (at 10 years).

Depressive symptoms were assessed at baseline. Cognitive functioning and difficulty with ADL were assessed at baseline and at 5 and 10 years.

Educational level moderates the relationship between depressive symptoms and cognitive functioning at 5 years (β = 0.07, SE = 0.03, p = 0.04, Cohen’s f2 = 0.02), being depressive symptoms related to poor cognitive functioning only at low educational levels. Cognitive functioning predicts difficulty with ADL at 5 and 10 years (β = −0.08, SE = 0.03, p = 0.008, Cohen’s f2 = 0.01; β = −0.09, SE = 0.03, p = 0.006, Cohen’s f2 = 0.02). The proposed model yielded excellent fit (CFI = 1.00, RMSEA = 0.0001, 90% CI 0.0001–0.03, SRMR = 0.004, and χ2(8) = 7.16, p = 0.52).

Cognitive reserve may act as a protective factor against the effect of depressive symptoms on cognition in older adults, which, in turn, is relevant to their functional independence.

Previous work using a US sample has shown that an index of social deprivation (SoDep Index) is associated with cognitive functioning and decline in older adults. This study aimed to replicate these findings using a European sample (Survey of Health, Ageing and Retirement in Europe, SHARE).

We analyzed data of 51,630 respondents aged 50 years and older (M: 63.5 years, standard deviation [SD]: 9.1) with at least two cognitive assessments (follow-up M: 6.06 years, SD: 3.86). Cognitive scores were transformed to Z-scores. Multiple growth curve modeling was used to model cognitive status and decline as predicted by the SoDep Index. In a sensitivity analysis, we constructed a new SoDep Index (SoDep Indexnew) including further social deprivation domains.

Adjusting for covariates, a unit increase in SoDep Index was associated with a cognitive score of 0.037 SDs smaller (p < .001) and a decline 0.003 SDs per year faster (p < .001). Of the covariates, depressive symptoms, chronic disease burden, male gender, and widowhood were also associated with poorer cognition. Being divorced was associated with better cognition. Sensitivity analysis confirmed findings. Compared to the SoDep Index, the SoDep Indexnew showed a more pronounced association with both cognition and cognitive decline.

We were able to replicate results showing an association between SoDep Index and cognitive function and decline. The sensitivity analysis further emphasizes the relevance of financial security. This strengthens the implication that preventing social deprivation can contribute to reducing the dementia burden by raising cognitive functioning in the older population. The findings are relevant to policy-makers and health care practitioners.

Residents of long term care facilities (LTCFs) and their professional caregivers have been hit hard by the coronavirus. During the COVID-19 outbreak, many countries imposed national visitor-bans for LTCFs. In the Netherlands, the ban was in place from 20 March 2020 onwards and ended (partly) on 15 June 2020. The usual meaningful and pleasant day structure that is created through organized (group) activities, was heavily impacted by the visitor ban. It remains unclear which particular types of activities were stopped, whether ‘alternative’ activities were introduced that may acquire a structural character in the future, and how this affected care workers.

We conducted online questionnaire research among LTCF residents, family members and care professionals at two time points; six weeks after the visitor-ban was implemented (T1) and one week after the ban was (partly) lifted (T2). The three groups received questionnaires on the consequences of the COVID-19 outbreak and the restrictive measures in place. Respondents were recruited independently for each measurement. This study only uses care professionals’ data. The influence of the up- and downscaling of activities on care professionals’ burden and ability to provide care was investigated using multivariate multiple linear regression.

811 professionals completed the questionnaire during T1 and 324 care workers during T2. A decrease in regular group activities during the visitor-ban was reported. Especially exercise activities, creative activities and music activities were undertaken less frequently. Also domestic activities, such as eating together and watching television, took place less frequently as compared to before the visitor-ban.

Activities that could be easily done on the unit, with sufficient social distance, were undertaken more frequently, such as music activities, conversations and playing games in the living room. The impact of the up- and downscaling of activities on care professional burden, and the perceived ability to provide adequate care, will be presented.

Activities are an important means for residents of long term care facilities for obtaining pleasure and giving a meaningful structure to the day. Future lessons can be learned from the adjustments that had to be made in the range of activities offered during the visitor-ban.

To evaluate the association between neuropsychiatric symptoms and apolipoprotein E (APOE) ϵ4 allele among older people in Central African Republic (CAR) and the Republic of Congo (ROC).

Multicenter population-based study following a two-phase design.

From 2011 to 2012, rural and urban areas of CAR and ROC.

People aged 65 and over.

Following screening using the Community Screening Interview for Dementia, participants with low cognitive scores (CSI-D ≤ 24.5) underwent clinical assessment. Dementia diagnosis followed the DSM-IV criteria and Peterson’s criteria were considered for Mild Cognitive Impairment (MCI). Neuropsychiatric symptoms were evaluated through the brief version of the Neuropsychiatric Inventory (NPI-Q). Blood samples were taken from all consenting participants before APOE genotyping was performed by polymerase chain reaction (PCR). Logistic regression models were used to evaluate the association between the APOE ϵ4 allele and neuropsychiatric symptoms.

Overall, 322 participants had complete information on both neuropsychiatric symptoms and APOE status. Median age was 75.0 years and 81.1% were female. Neuropsychiatric symptoms were reported by 192 participants (59.8%) and at least 1 APOE ϵ4 allele was present in 135 (41.9%). APOE ϵ4 allele was not significantly associated with neuropsychiatric symptoms but showed a trend toward a protective effect in some models.

This study is the first one investigating the association between APOE ϵ4 and neuropsychiatric symptoms among older people in sub-Saharan Africa (SSA). Preliminary findings indicate that the APOE ϵ4 allele was not associated with neuropsychiatric symptoms. Further research seems, however, needed to investigate the protective trend found in this study.

Prior neuropsychiatric disturbances are risk factors for stroke. There is a knowledge gap on the predictors of prestroke psychopathology, as well as their association with stroke outcomes in survivors living in low- and middle-income countries (LMICs). We estimated prevalence, predictors, and association of prestroke neuropsychiatric symptoms with poststroke depression (PSD), disability, and mortality.

Prospective observation.

Nigeria.

Adult ischemic and hemorrhagic stroke survivors.

Prestroke psychopathology were ascertained using the Neuropsychiatric Inventory Questionnaire (NPI-Q). Outcomes were assessed using validated tools, including the Centre for Epidemiologic Studies – Depression Scale (CES-D 10) and modified Rankin scale (mRS). Independent associations were investigated using regression models with Bonferroni corrections, and presented as standardized mean differences (SMD) and odds ratios (OR) within 95% confidence intervals (CI).

Among 150 participants, prestroke neuropsychiatric symptoms were found in 78 (52%). In multivariate logistic regression analyses, prestroke sleep disturbance was associated with systemic hypertension (OR = 5.39, 95% CI = 1.70–17.08). Prestroke neuropsychiatric symptoms independently predicted worse motor disability scores (SMD = 0.92, 95% CI = 0.21–1.62) and greater odds of poststroke mortality (OR = 2.7, 95% CI = 1.1–7.0) at 3 months. However, prestroke depression was not significantly associated with PSD.

Prestroke sleep disturbances was associated with systemic hypertension, a key index of high cardiovascular risk profile and stroke. The findings should energize before-the-stroke identification and prioritization of limited treatment resources in LMICs to persons with sleep symptoms who have multiple, additional, risks of stroke.

To confirm the factor validity of the Compassionate Engagement and Action Scales (CEAS), as set out in the original development study, when used with a sample of family carers of older adults.

A series of confirmatory factor analyses were undertaken to test the previously proposed factor solutions of each scale.

As part of a larger cross-sectional survey, the scales were completed online or via hard copy between July and December 2019.

An international sample of 171 family carers of adults aged 65 years or older.

The CEAS are three measures that individually assess Compassion for Self, Compassion to Others, and Compassion from Others. All scales measure two aspects, “engagement” and “actions” (two-factor solution), and Compassion for Self also measures two further dimensions within engagement: “sensitivity to suffering” and “engagement with suffering” (three-factor solution).

Results were largely consistent with the two-factor solutions proposed for the three orientations of compassion, with acceptable fit and good internal reliability. There was some support for the three-factor solution of Compassion for Self; however, despite model fit comparable to the two-factor solution, internal reliability of the delineated “engagement” dimensions was low, and there was a weak factor loading for item 5 that measured distress tolerance.

Use of the CEAS with family carers of older adults is promising. Further research is recommended with larger samples and to explore distress tolerance as a competency within conceptualization and measurement of compassion.

To review the currently available data on the use of ketamine in the treatment of depression among older adults from randomized controlled studies.

Randomized controlled trials.

Variable.

60 years and older with depression.

Ketamine.

Change in Montgomery–Asberg Depression Rating Scale (MADRS) scores.

Two studies met the inclusion criteria. The first study showed a significant reduction in depression symptoms with use of repeated subcutaneous ketamine administration among older adults with depression. The second study failed to achieve significance on its primary outcome measure but did show a decrease in MADRS scores with intranasal ketamine along with a higher response and remission rates in esketamine group compared with the placebo group. The adverse effects from ketamine generally lasted only a few hours and abated spontaneously. No cognitive adverse effects were noted in either trial from the use of ketamine.

The current evidence for use of ketamine among older adults with depression indicates some benefits with one positive and one negative trial. Although one of the trials did not achieve significance on the primary outcome measure, it still showed benefit of ketamine in reducing depressive symptoms. Ketamine was well tolerated in both studies with adverse effects being mild and transient.

Post-diagnostic psychosocial interventions could play an important role in supporting people with mild dementia remain independent. The Promoting Independence in Dementia (PRIDE) intervention was developed to address this.

The mixed methods non-randomized, pre-post feasibility study occurred across England. Facilitators were recruited from the voluntary sector and memory services. Participants and their supporters took part in the three-session intervention. Outcome measures were collected at baseline and follow-up. To evaluate acceptability, focus groups and interviews were conducted with a subsample of participants and facilitators.

Contextual challenges to delivery including national research governance changes, affected recruitment of study sites. Thirty-four dyads consented, with 14 facilitators providing the intervention. Dyads took part in at least two sessions (79%), and 73% in all three. Outcome measures were completed by 79% without difficulty, with minimal missing data. No significant changes were found on pre and post assessments. Post hoc analysis found moderate effect size improvements for self-management (SMAS instrument) in people with dementia (d = 0.41) and quality of life (EQ5D measure) in carers (d = 0.40). Qualitative data indicated that dyads found PRIDE acceptable, as did intervention facilitators.

The three-session intervention was well accepted by participant-dyads and intervention facilitators. A randomized controlled trial of PRIDE would need to carefully consider recruitment potential across geographically varied settings and site stratification according to knowledge of contextual factors, such as the diversity of post-diagnostic services across the country. Letting sites themselves be responsible for identifying suitable intervention facilitators was successful. The self-report measures showed potential to be included in the main trial.

Nursing home (NH) residents with dementia is exposed to high rates of psychotropic prescriptions. Our objectives were to: (1) pool the prevalence estimates of psychotropic polypharmacy from the existing literature and (2) examine potentially influential factors that are related to a higher or lower prevalence.

Meta-analysis of data collected from randomized trials, quasi-experimental, prospective or retrospective cohort, and cross-sectional studies. English-language searches of PubMed and PsycINFO were completed by November 2020. Included studies reported prevalence estimates of psychotropic polypharmacy (i.e. defined as either two-or-more or three-or-more medications concurrently) in NH residents with dementia.

NH residents with dementia.

Random-effects models were used to pool the prevalence of psychotropic polypharmacy in NH residents with dementia across studies. Estimates were provided for both two-or-more and three-or-more concurrent medications. Heterogeneity and publication bias were measured. Meta-regression examined the influence of the percentage of the sample who were male, mean age of the sample, geographic region (continent), sample size, and study year on the prevalence of psychotropic polypharmacy.

Twenty-five unique articles were included comprising medications data from 92,370 NH residents with dementia in 12 countries. One-in-three (33%, [95% CI: 28%, 39%]) NH residents with dementia received two-or-more psychotropic medications concurrently. One-in-eight (13%, [95% CI: 10%, 17%]) received three-or-more psychotropic medications concurrently. Estimates were highly variable across both definitions of psychotropic polypharmacy (p < 0.001). Among study-level demographics, geographic region, sample size, or study year, only male sex was associated with greater use of two-or-more psychotropic medications (Unadjusted OR = 1.02, p = 0.006; Adjusted OR = 1.04, p = 0.07).

Psychotropic polypharmacy is common among NH residents with dementia. Identifying the causes of utilization and the effects on resident health and well-being should be prioritized by federal entities seeking to improve NH quality.

Evidence linking subjective concerns about cognition with poorer objective cognitive performance is limited by reliance on unidimensional measures of self-perceptions of aging (SPA). We used the awareness of age-related change (AARC) construct to assess self-perception of both positive and negative age-related changes (AARC gains and losses). We tested whether AARC has greater utility in linking self-perceptions to objective cognition compared to well-established measures of self-perceptions of cognition and aging. We examined the associations of AARC with objective cognition, several psychological variables, and engagement in cognitive training.

Cross-sectional observational study.

The sample comprised 6056 cognitively healthy participants (mean [SD] age = 66.0 [7.0] years); divided into subgroups representing middle, early old, and advanced old age.

We used an online cognitive battery and measures of global AARC, AARC specific to the cognitive domain, subjective cognitive change, attitudes toward own aging (ATOA), subjective age (SA), depression, anxiety, self-rated health (SRH).

Scores on the AARC measures showed stronger associations with objective cognition compared to other measures of self-perceptions of cognition and aging. Higher AARC gains were associated with poorer cognition in middle and early old age. Higher AARC losses and poorer cognition were associated across all subgroups. Higher AARC losses were associated with greater depression and anxiety, more negative SPA, poorer SRH, but not with engagement in cognitive training.

Assessing both positive and negative self-perceptions of cognition and aging is important when linking self-perceptions to cognitive functioning. Objective cognition is one of the many variables – alongside psychological variables – related to perceived cognitive losses.

Over 400,000 people live in care home settings in the UK. One way of understanding and improving the quality of care provided is by measuring and understanding the quality of life (QoL) of those living in care homes. This review aimed to identify and examine the psychometric properties including feasibility of use of dementia-specific QoL measures developed or validated for use in care settings.

Systematic review.

Instruments were identified using four electronic databases (PubMed, PsycINFO, Web of Science, and CINAHL) and lateral search techniques. Searches were conducted in January 2017. Studies which reported on the development and/or validation of dementia specific QoL instruments for use in care settings written in English were eligible for inclusion. The methodological quality of the studies was assessed using the COSMIN checklist. Feasibility was assessed using a checklist developed specifically for the review.

Six hundred and sixteen articles were identified in the initial search. After de-duplication, screening and further lateral searches were performed, 25 studies reporting on 9 dementia-specific QoL instruments for use in care home settings were included in the review. Limited evidence was available on the psychometric properties of many instruments identified. Higher-quality instruments were not easily accessible or had low feasibility of use.

Few high-quality instruments of QoL validated for use in care home settings are readily or freely available. This review highlights the need to develop a well-validated measure of QoL for use within care homes that is also feasible and accessible.

Cumulative evidence suggests that health-related risk factors during midlife and old-age are associated with cognitive impairment. However, studies are needed to clarify the association between early-life risk factors and impaired cognitive functioning to increment existing knowledge.

To examine the association between childhood infectious diseases and late-life cognitive functioning in a nationally representative sample of older adults.

Eligible respondents were 2994 community-dwelling individuals aged 65–85.

Cognitive functioning was assessed using the Mini-Mental State Examination (MMSE). Childhood infectious diseases (i.e. chicken pox, measles, and mumps) were self-reported. The study covariates were age, sex, highest educational level achieved, smoking status, body mass index, and depression. The primary statistical analysis examined the association between the number of childhood infectious diseases and total MMSE scores, accounting for all study covariates. Regression models of progressive complexity were examined for parsimony. The robustness of the primary results was tested in 17 sensitivity analyses.

The most parsimonious model was a linear adjusted model (Bayesian Information Criterion = 12646.09). Late-life cognitive functioning significantly improved as the number of childhood infectious diseases increased (β = 0.18; 95% CI = 0.11, 0.26; p < 0.001). This effect was not significantly attenuated in all sensitivity analyses.

The current study results are consistent with prior ecological findings indicating that some childhood infectious diseases are associated with better cognitive functioning in old-age. This points to an early-life modifiable risk factor associated with older-life cognitive functioning. Our results may reflect selective mortality and/or beneficial effects via hormetic processes.

Loneliness and physical activity are important targets for research into the impact of COVID-19 because they have established links with mental health, could be exacerbated by social distancing policies, and are potentially modifiable. In this study, we aimed to identify whether loneliness and physical activity were associated with worse mental health during a period of mandatory social distancing in the UK.

Population-based observational cohort study.

Mental health data collected online during COVID-19 from an existing sample of adults aged 50 and over taking part in a longitudinal study of aging. All had comparable annual data collected between 2015 and 2019.

Three-thousand two-hundred and eighty-one participants aged 50 and over.

Trajectories of depression (measured by PHQ-9) and anxiety (measured by GAD-7) between 2015 and 2020 were analyzed with respect to loneliness, physical activity levels, and a number of socioeconomic and demographic characteristics using zero-inflated negative binomial regression.

In 2020, PHQ-9 score for loneliness, adjusted for covariates, was 3.23 (95% CI: 3.01–3.44), an increase of around 1 point on all previous years in this group and 2 points higher than people not rated lonely, whose score did not change in 2020 (1.22, 95% CI: 1.12–1.32). PHQ-9 was 2.60 (95% CI: 2.43–2.78) in people with decreased physical activity, an increase of .5 on previous years. In contrast, PHQ-9 in 2020 for people whose physical activity had not decreased was 1.66, 95% CI: 1.56−1.75, similar to previous years. A similar relationship was observed for GAD-7 though the absolute burden of symptoms lower.

After accounting for pre-COVID-19 trends, we show that experiencing loneliness and decreased physical activity are risk factors for worsening mental health during the pandemic. Our findings highlight the need to examine policies which target these potentially modifiable risk factors.

People working in long-term care homes (LTCH) face ethical dilemmas about how to minimize the risk of spread of COVID-19, while also minimizing psychological hardship and other harms of infection control measures on residents. The Dementia Isolation Toolkit (www.dementiaisolationtoolkit.com; DIT) was developed to address the gap in ethical guidance for LTCH on how to safely and effectively isolate people with dementia while supporting the personhood and well-being of residents. In this presentation, we will present the DIT and report on the results of a survey of LTCH staff in Ontario, Canada on their experiences isolating residents in LTCH and the use of the DIT in supporting person-centred isolation care.

A link to an online survey was distributed to LTCH staff through provincial organizations and agencies as well as through social media and the DIT website. Inclusion criteria were LTCH staff working on-site at a LTCH since March 1, 2020, who had direct or indirect experience with the isolation/quarantine of LTCH residents. Results were summarized descriptively.

A broad sample of LTCH staff (n=207) participated in the survey, most of whom had experienced an outbreak in their LTCH. Dementia (96%) was the most important barrier to implementation of infection control measures in LTCH, followed by staff distress about the effects of isolation on residents (61%). Important facilitators for isolation included delivery of 1:1 activities in the resident’s room (81%) and designating essential caregivers to provide support (67%), while inadequate staffing levels were reported as a barrier (55%). 65% of respondents indicated some familiarity with the DIT, and of those who had used the toolkit, 62% found it helpful in supporting isolation care, particularly in developing care plans and making and communicating decisions. Of those who had used the DIT, 48% found it fairly or very helpful at reducing their level of distress.

Isolation as an infection control and prevention (ICP) measure in LTCH environments can be harmful to residents and create moral distress in staff. ICP guidance and support of LTCH needs to address how to minimize these harms by providing dementia-specific guidance such as in the DIT.

Before drawing conclusions on the contribution of an effective intervention to daily practice and initiating dissemination, its quality and implementation in daily practice should be optimal. The aim of this process evaluation was to study these aspects alongside a randomized controlled trial investigating the effects of a multidisciplinary biannual medication review in long-term care organizations (NTR3569).

Process evaluation with multiple measurements.

Thirteen units for people with dementia in six long-term care organizations in the Netherlands.

Physicians, pharmacists, and nursing staff of participating units.

The PROPER intervention is a structured and biannually repeated multidisciplinary medication review supported by organizational preparation and education, evaluation, and guidance.

Web-based questionnaires, interviews, attendance lists of education sessions, medication reviews and evaluation meetings, minutes, evaluation, and registration forms.

Participation rates in education sessions (95%), medication reviews (95%), and evaluation meetings (82%) were high. The intervention’s relevance and feasibility and applied implementation strategies were highly rated. However, the education sessions and conversations during medication reviews were too pharmacologically oriented for several nursing staff members. Identified barriers to implementation were required time, investment, planning issues, and high staff turnover; facilitators were the positive attitude of professionals toward the intervention, the support of higher management, and the appointment of a local implementation coordinator.

Implementation was successful. The commitment of both higher management and professionals was an important factor. This may partly have been due to the subject being topical; Dutch long-term-care organizations are pressed to lower inappropriate psychotropic drug use.
