Alzheimer’s disease (AD), the most common type of dementia, is one of the most feared diseases, obstructing help-seeking, and leading to discrimination. While research interest in fear of developing AD is increasing, little is known about its characterization, triggers, and consequences, especially among different cultures. In this study, we aimed at exploring and characterizing AD fear as experienced by laypersons (LP), persons with Mild Neurocognitive Disorder (MND), and their relatives, in Israel and Germany.

A qualitative study using focus groups (FGs) and semi-structured interviews was used. Thematic content analysis was conducted to extract key themes.

Israeli and German not yet diagnosed people.

The study included a total of 130 participants (63 Israeli and 67 German participants) representing 3 groups: LP (n = 82), persons with MND (n = 28), and relatives of persons with MND (n = 20).

Two overarching themes were identified across groups and countries: fear of developing AD and fear of stigmatization. Other types of fear, such as fear of a person with AD, fear about the impact of a diagnosis of AD on family members, fear of becoming a caregiver, and fear of losing one’s self-determination because of developing AD, were specific to a group type or country. Different types of fear were awakened by different triggers, and were dealt with different coping strategies.

To examine the relative contributions of frailty and neuropathology to dementia expression in a population-based cohort study.

Cross-sectional analysis of observational data.

Population-representative clinicopathological cohort study.

Adults aged 75+ recruited from general practice registries in Cambridge, UK, in 1985.

A 39-item frailty index and 15-item neuropathological index were used to operationalize frailty and neuropathology, respectively. Dementia status was ascertained by clinical consensus at time of death. Relationships were evaluated using logistic regression models in participants with autopsy records (n = 183). Model fit was assessed using change in deviance. Population attributable fraction for frailty was evaluated in relation to dementia incidence in a representative sample of the survey participants (n = 542).

Participants with autopsy were 92.3 ± 4.6 years at time of death, and mostly women (70%). Average frailty index value at last survey before death was 0.34 ± 0.16. People with dementia (63% of the sample) were frailer, had lower MMSE scores, and a higher burden of neuropathology. Frailty and neuropathological burden were significantly and independently associated with dementia status, without interaction; frailty explained an additional 3% of the variance in the model. Assuming a causal relationship and based on population-attributable fraction analyses, preventing severe frailty (Frailty Index ≥ 0.40) could have avoided 14.2% of dementia cases in this population-based cohort.

In the very old, frailty contributes to the risk for dementia beyond its relationship with the burden of traditional dementia neuropathologies. Reducing frailty could have important implications for controlling the burden of dementia. Future research on frailty interventions should include dementia risk as a key outcome, public health interventions and policy decisions should consider frailty as a key risk factor for dementia, and biomedical research should focus on elucidating shared mechanisms of frailty and dementia development.

Sleep disturbances are common in people with dementia and increase with the severity of the disease. Sleep disturbances are complex and caused by several factors and are difficult to treat. There is a need for more robust and systematic studies dealing with sleep disturbances in older people with dementia. The aim of this study was to investigate effects from robot-assisted (Paro) group activity on sleep patterns in nursing home (NH) residents with dementia.

A cluster randomized controlled trial.

Special care units in 10 NH in Norway.

A total of 60 participants over 65 years with dementia were recruited. Thirty participants were recruited to the intervention group and 30 participants to the control group.

Participants participated in group activity with Paro for 30 minutes twice a week over 12 weeks or in control group (treatment as usual).

Sleep–wake patterns were assessed objectively by 7 days of wrist actigraphy before and after the intervention. Data were collected between March 2013 and September 2014. Data were analyzed using mixed models.

Positive effects on change in sleep were found in the intervention group as compared with the control group. The intervention group increased percentage of sleep efficiency, increased the amount of total sleep time and reduced number of nocturnal awakenings. In addition, a significant effect was found in reduced awakenings after sleep onset.

Social stimulation through engaging group activity could contribute to improved sleep in people with dementia in NH. Increased sleep efficiency and total sleep time, in addition to fewer night awakenings, affect central indicators of good sleep quality across the life span. Improved sleep quality will also affect quality of life and comorbidities in vulnerable groups. We believe group activity with Paro to be an accessible and feasible non-pharmacological treatment for those who enjoy Paro.

This study compared dementia knowledge between older Chinese adults in Melbourne, Australia, and Beijing, China, and explored factors associated with dementia knowledge between these two groups. Ultimately, this study aimed to inform the development of tailored dementia education programs for older Chinese adults.

A cross-sectional design was employed in this study.

Participants were recruited from 5 Chinese community senior groups in Melbourne and 10 community health centers in Beijing from March to May 2019.

A total of 379 older Chinese adults aged 50 and over completed the questionnaire, including 153 from Melbourne and 226 from Beijing.

Dementia knowledge was assessed using the Alzheimer’s Disease Knowledge Scale (ADKS). Demographic characteristics, dementia-related experience, and the mental health status of participants were collected. Stepwise linear regression was used to analyze the factors associated with dementia knowledge.

In general, older Chinese adults in Melbourne and Beijing reported similar levels of dementia knowledge for both the overall ADKS scale (mean ± SD: 17.2 ± 2.9 in Melbourne vs. 17.5 ± 2.9 in Beijing, p > 0.05) and the seven subdomains. Of the subdomains, the highest correct response rates were observed in the life impact of the dementia subdomain, and the lowest rates were observed in the caregiving subdomain. Stepwise linear regression analysis revealed that younger age and self-reported dementia worry were significantly associated with higher levels of dementia knowledge in the Melbourne group, whereas a positive family history of dementia was significantly associated with higher levels of dementia knowledge in the Beijing group.

Older Chinese adults living in Melbourne and Beijing share similar levels of dementia knowledge, but factors associated with their knowledge are different. These findings will inform the development of culturally and socially appropriate dementia education programs for older Chinese populations in different countries.

To develop a staff training intervention for agitation in people with severe dementia, reaching end-of-life, residing in nursing homes (NHs), test feasibility, acceptability, and whether a trial is warranted.

Feasibility study with pre- and post-intervention data collection, qualitative interviews, and focus groups.

Three NHs in South East England with dementia units, diverse in terms of size, ownership status, and location.

Residents with a dementia diagnosis or scoring ≥2 on the Noticeable Problems Checklist, rated as “severe” on Clinical Dementia Rating Scale, family carers, and staff (healthcare assistants and nurses).

Manualized training, delivered by nonclinical psychology graduates focusing on agitation in severe dementia, underpinned by a palliative care framework.

Main outcomes were feasibility of recruitment, data collection, follow-up, and intervention acceptability. We collected resident, family carer, and staff demographics. Staff provided data on resident’s agitation, pain, quality of life, and service receipt. Staff reported their sense of competence in dementia care. Family carers reported on satisfaction with end-of-life care. In qualitative interviews, we explored staff and family carers’ views on the intervention.

The target three NHs participated: 28 (49%) residents, 53 (74%) staff, and 11 (85%) family carers who were eligible to participate consented. Eight-four percent of staff attended ≥3 sessions, and we achieved 93% follow-up. We were able to complete quantitative interviews. Staff and family carers reported the intervention and delivery were acceptable and helpful.

The intervention was feasible and acceptable indicating a larger trial for effectiveness may be warranted.

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.
