Objectives: Investigate whether the coexistence of pain and depressive symptoms is a risk factor for cognitive decline in individuals aged 50 or older.

Method: Longitudinal trajectory study involving 4,718 participants from the English Longitudinal Study of Ageing (ELSA). Joint pain was self-reported, and intensity was classified as mild, moderate/intense. Depressive symptoms were investigated using the Centre for Epidemiologic Studies Depression Scale (CES-D-8 ≥ 4). The sample was divided into six groups: no pain and no depression (NP/NDe), mild pain and no depression (MP/NDe), moderate/intense pain and no depression (M-IP/NDe), no pain and depression (NP/De), mild pain and depression (MP/De), and moderate/intense pain and depression (M-IP/De). The outcome of interest was performance in memory, executive function, and global cognition. Generalised linear mixed models were used to analyse performance in the cognitive domains and global cognition score as a function of pain and depressive symptoms during 12 years of follow-up.

Results: Over time, individuals with M-IP/De had a greater memory decline (-0.038 SD/year, 95%CI: -0.068 to -0.007) and the global cognition score (-0.033 SD/year, 95%CI: -0.063 to -0.002) than those with NP/NDe.

Conclusion: The coexistence of moderate/intense pain and depressive symptoms is a risk factor for the decline of global cognition and memory.

Objectives: Care-related beliefs are considered risk factors for decreased mental health in family caregivers of people with dementia. However, their exact role in the caregiver stress process remains unclear. Hence, we tested a cognitive vulnerability-stress model of depression and anxiety in family caregivers of people with dementia.

Method: A cross-sectional study was conducted using baseline data from a caregiver intervention trial (N = 322). Within Bayesian moderated mediation analysis, we examined mediation of effects of objective demands (severity of dementia, challenging behavior, caregiving intensity, caregiving duration) on depression and anxiety via subjective caregiver burden and moderation by care-related beliefs in four domains (dysfunctional caregiving standards, dysfunctional attitudes towards dementia, functional self-care-related beliefs, functional acceptance-related beliefs).

Results: The relation between objective demands and subjective burden was amplified by dysfunctional caregiving standards and dysfunctional attitudes towards dementia and mitigated by functional self-care-related beliefs. Further, functional acceptance-related beliefs attenuated the effect of subjective caregiver burden on depression.

Conclusion: The study provides preliminary evidence for a cognitive vulnerability-stress model of depression and anxiety in family caregivers of people with dementia. The results indicate that the four-domain model of care-related beliefs is a valuable framework for future research and may serve as a heuristic model for cognitive-behavioral therapy in this population.

Objectives: This study investigates factors associated with the person with dementia and the caregiver to identify those associated with an increased risk of transition to a care home.

Method: IDEAL data were collected at baseline and at 12- and 24-month follow-up for 1545 people with dementia and 1305 caregivers. Modified Poisson regressions with an offset for 'person years at risk' were used. Person with dementia factors explored were personal characteristics, cognition, health, self- and informant-rated functional ability, and neuropsychiatric symptoms. Caregiver factors explored were personal characteristics, stress, health, and quality of the dyadic relationship.

Results: A 5% people moved into care. Risk of moving into a care home was higher among people with dementia who were ≥80 years, among people with Parkinson's disease dementia or dementia with Lewy bodies, and among those without a spousal caregiver. Poorer cognition and more self-rated or informant-rated functional difficulties increased the risk of moving into care.

Conclusion: Factors related to increased dementia severity and greater disability are the primary influences that place people with dementia at greater risk of moving into a care home. Strategies that help to maintain everyday functional ability for people with dementia could help delay people with dementia moving into care.

Objective: This study aimed to map the existing scientific research about solitude in older adults, focusing on its conceptualizations, associated factors, and impacts.

Method: A scoping review was conducted, searching Scopus, Web of Science, PubMed, and Academic Search Complete databases for publications from 1985 until December 2023.

Results: Twenty-four studies were included. The main findings suggest a wide-ranging conceptualisation of solitude, with most studies (n = 16) adopting neutral definitions such as "being alone, without communicating with others"; and a subset of studies adopting definitions that alluded to "positive solitude" (as the choice of being with oneself, underscoring potential benefits). Individual characteristics were identified as key associated factors of solitude. Both positive impacts and negative impacts were reported.

Conclusion: The variability in conceptualisation and impacts likely stems from methodological and theoretical differences in approaching solitude. This underscores the need for additional research to establish a widely accepted conceptual framework. Such consensus could enhance the understanding of the conditions contributing to positive and negative impacts associated with solitude and inform targeted interventions.

Objectives: COVID-19 lockdowns were introduced to control the pandemic, however, they resulted in a global disruption of daily life and of individual and global health. Reduced accessibility of health services, unavailability of food and drugs, and mental health challenges had a huge impact on older people and on people living with disabling conditions such as Parkinson's disease (PD). We assessed whether and to what extent the more disabled and vulnerable people with Parkinson's (PwP) were affected by lockdowns.

Method: We analysed responses collected through a web-based survey of PwP according to their self-sufficiency [self-sufficient (SS); nearly self-sufficient (nSS); non-self-sufficient, cared for by family (NSS/F); non-self-sufficient, needs professional care (NSS/PC)].

Results: Fears due to COVID-19 and difficulties with food supply were highest in NSS/F PwP. Difficulties with the supply of Parkinson's medication or other drugs were apparently not an issue, while problems accessing primary care physicians and neurologists were similar across all patient groups. On the contrary, difficulties with daily and motor activities were higher in NSS/F and NSS/PC PwP. PwP symptoms worsened in all groups, with NSS/F and NSS/PC participants experiencing the worst deterioration. Notably, the deterioration of PwP symptoms was specifically related to changes in daily and motor activities, with participants who reported less engagement in daily and motor activities experiencing the worst deterioration.

Conclusion: Findings strongly support the need for decision-makers and healthcare providers to carefully re-evaluate the risk-benefit ratio of limiting healthcare accessibility for PwP, since evidence shows that lockdown measures primarily impact the groups who are most fragile and vulnerable.

Objectives: Frontotemporal Degeneration (FTD) is a common cause of early onset dementia with symptoms often presenting before 65 years of age and adding tremendous burden on caregivers. FTD caregiving research describes patient behavioral symptoms such as apathy and disinhibition as primary sources of poor caregiver psychological health; however, little attention has been paid to other common patient behaviors, such as loss of empathy. To better understand the relationship between empathy loss and FTD caregiver outcomes, this integrative review aimed to address the question: How does the loss of empathy in a person living with FTD (PLwFTD) impact the caregiver?

Method: Quantitative and qualitative articles were found in PubMed, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Scopus and were assessed for quality using the Crowe Critical Appraisal Tool (CCAT). Through constant comparative analysis, articles were assessed to abstract common themes in the literature.

Results: From 333 citations, 8 qualitative and 8 quantitative studies published between 2010 and 2022 were included. Three main themes were uncovered: 1) caregiver emotional reactions to the PLwFTD; 2) caregiver psychological distress; 3) changes in the relationship.

Conclusion: This review emphasizes the detrimental impact of empathy loss on FTD caregivers. Understanding these underexplored consequences is critical in understanding the well-being of caregivers and promoting ways to support caregivers.

Objectives: Dignity of patients with early-stage dementia (PwESD) is a core value of person-centered care. To evaluate the effectiveness of the intervention programs targeted at this population, a reliable tool that would measure dignity in PwESD is needed. Based on a qualitative analysis of how PwESD perceive and experience dignity, this study aims to determine the adequacy of the Czech version of the Patient Dignity Inventory (PDI-CZ) for this patient population.

Method: The sample from two outpatient clinics in Czechia included home-dwelling individuals aged 60 years or older with mild dementia. In the first interview (T1), there were 21 respondents; 10 of whom participated in the second interview (T2) that was conducted after 12 months. The qualitative material was analyzed using a deductive approach based on the PDI-CZ domains.

Results: Thematic analysis shows that the PwESD thematized all domains of the PDI-CZ in their interviews and their views of dignity were stable over time. Some experiences were not considered in the PDI-CZ (such as lowered support of the society, lowered ability to advocate for oneself, or feeling of not suitable living conditions).

Conclusion: When developing a revised version of the tool, items that reflect missing views of dignity should be included.

Objectives: We performed a systematic review and meta-analysis to examine the prevalence and antecedents/consequences of chronic loneliness and social isolation (i.e. enduring or persistent experience that extends over a certain period of time) among older adults. Moreover, we conducted a meta-regression to explore sources of heterogeneity.

Method: A search was conducted in four electronic databases. We included observational studies that reported prevalence and, where available, antecedents/consequences of chronic loneliness or chronic social isolation amongst older adults. Key characteristics of the studies were extracted.

Results: Across 17 studies included in the meta-analysis, the estimated prevalence of chronic loneliness was 20.8% (95% CI: 16.1-25.5%), including 21.7% among women (95% CI: 16.1-27.4%) and 16.3% among men (95% CI: 10.6-21.9%). One study reported chronic social isolation (13.4%) and found that chronic social isolation predicted higher depression scores. Meta-regressions indicated that loneliness was less prevalent when assessed with single-item measures. Regarding antecedents/consequences, spousal loss can contribute to chronic loneliness which in turn may contribute to adverse health-related outcomes.

Conclusion: About one in five older adults experiences chronic loneliness reflecting the need to address chronic loneliness. More longitudinal research is needed on chronic loneliness and social isolation, particularly from low and middle-income countries.

Objectives: To gain insight into the longitudinal, reciprocal associations between depressive symptoms and sexual satisfaction as well as the potential moderating roles of gender and perceived importance of sexuality.

Method: We analyzed longitudinal data from 2113 participants of the Longitudinal Ageing Study Amsterdam (LASA) with an initial age range of 54-93 years, using Generalized Estimating Equations (GEE).

Results: There were no significant associations between baseline depressive symptoms and change in sexual satisfaction, nor between baseline sexual satisfaction and change in depressive symptoms. Gender and perceived importance of sexuality were moderators: in men higher depression scores were associated with a decrease in sexual satisfaction, whereas in women higher depression scores were associated with an increase in sexual satisfaction. In participants for whom sexual life was important, higher depression scores were associated with a decrease in sexual satisfaction. In participants for whom sexual life was not important, higher depression scores were associated with an increase in sexual satisfaction.

Conclusion: The associations between baseline depressive symptoms and change in sexual satisfaction as well as between baseline sexual satisfaction and change in depressive symptoms varied according to gender and importance ascribed to sexuality. Potential explanations might lie in the different roles sexual activity plays in sexual satisfaction in men and women.

Objectives: To evaluate and rank the effectiveness of specific non-pharmacological treatments (NPTs) in improving the global cognitive function in individuals with Alzheimer's disease (AD) and to examine the dose-response relationship.

Method: We conducted a systematic search in PubMed, MEDLINE, Embase, PsycINFO, CENTRAL, WOS, and CNKI from their inception to 15 February 2023. Standardized mean differences (SMD) and 95% confidence intervals (CI) were calculated for outcomes using random effects models.

Results: We included 68 studies involving 5053 participants in this meta-analysis. The treatments with the highest cumulative probabilities for improving global cognitive function were transcranial direct current stimulation (tDCS), followed by physical exercise (PE), and repetitive transcranial magnetic stimulation (rTMS). Additionally, cognitive stimulation (CS), cognitive training CT), multidisciplinary program (MD), and reminiscence treatment (RT) also significantly improve the global cognitive function of people with AD. A non-linear dose-response association was observed for tDCS, PE, rTMS, CS, and CT with global cognitive improvement. Notably, no minimal threshold was identified for the beneficial effects of PE on cognition. The estimated minimal doses for clinically relevant changes in cognition were 33 min per week for tDCS, 330 MET-min per week for PE, and 8000 pulses per week for rTMS.

Conclusion: tDCS, PE, and rTMS are the better effective NPTs for enhancing global cognitive function in individuals with AD. Properly dosing these treatments can yield significant clinical benefits. Our findings support the clinical utility of low-dose exercise in improving cognition in people with AD.
