Objectives: This study investigates the mediating roles of autonomic function and mental health in the association between sleep and cognitive decline in adults aged 50 and above.

Method: A total of 2,697 participants with observations on sleep and mediators at baseline and repeated measures of cognitive function (MMSE) were included. Clusters of individuals with similar cognitive trajectories (high-stable, mid-stable and low-declining) were identified. Multinomial logistic regressions were used to estimate the likelihood of membership to each trajectory group based on sleep duration and disturbance. Finally, mediation analysis tested potential mediating effects of autonomic function and mental health underpinning the sleep-cognition relationship.

Results: Short (p = .028), long (p =.019), and disturbed sleep (p =.008) increased the likelihood of a low-declining cognitive trajectory. Mental health measures fully attenuated relationships between cognitive decline and short or disturbed sleep but not long sleep. No autonomic function mediation was observed.

Conclusion: Older adults with short or disturbed sleep are at risk of cognitive decline due to poor mental health. Individuals with long sleep are also at risk, however, the acting pathways remain to be identified. These outcomes have clinical implications, potentially identifying intervention strategies targeting mental health and sleep as prophylactic measures against dementia.

Objectives: Prior studies reporting the effects of loneliness on mild impairment cognitive (MCI) have generated inconsistent results. This meta-analysis aimed to investigate the longitudinal association between loneliness and risk of MCI among community-dwelling middle-aged and older adults.

Method: Five electronic databases were searched from inception to 9 May 2023. Eligible studies examined the longitudinal association between loneliness and cognitive outcomes, including incident MCI, cognitive impairment, and cognitive decline. Odds ratios (OR) and 95% confidence intervals (CIs) were calculated using random-effects or fixed-effects meta-analysis. Sensitivity analysis and subgroup analysis were conducted. Publication bias was examined using Egger's and Begg tests.

Results: Eight studies were included. Among the 45,032 participants, 10,570 were diagnosed with MCI/cognitive decline. Loneliness was positively associated with an increased risk of MCI (overall OR = 1.14; 95% CI = 1.05, 1.23), with moderate heterogeneity (I² = 44.2%). Sensitivity analysis have minimal influence on the aforementioned pooled effect. Subgroup analyses indicated stronger associations in studies which employed incident MCI as cognitive outcome (OR = 2.55, 95%CI = 1.31, 1.83), were conducted in non-Asia countries (OR = 1.52, 95%CI = 0.95, 1.20), and reported no depression adjustment (OR = 1.51, 95%CI = 1.04, 1.25). The association between loneliness and MCI was stronger among males compare to females. The Egger test and Begg test showed no evidence of significant publication bias (p = .493; p = .474).

Conclusion: The findings indicated that loneliness was associated with an increased risk of MCI. Future longitudinal studies should evaluate potential cases of MCI through comprehensive clinical assessments by practitioners to draw robust findings on the association of loneliness with MCI.

Objectives: This study examined the mediating role of care partner burden on the relationship between patient clinical factors (i.e. cognition, physical function, and behavioral and psychological symptoms of dementia [BPSD]) and care partner mental health (i.e. anxiety and depression) among dementia care partners at hospital discharge.

Method: The sample consisted of 431 patient and care partner dyads enrolled in the Family centered Function-focused Care (Fam-FFC) study; ClinicalTrials.gov identifier NCT03046121. Mediation analyses were conducted to test the role of care partner burden on the associations between patient clinical factors, and care partner anxiety and depression.

Results: Mediation models demonstrated that care partner burden partially mediated the relationship between patient physical function and care partner anxiety and depression, as well as patient BPSD and care partner anxiety and depression.

Conclusion: Findings highlight the need for clinicians and service providers to implement comprehensive strategies that address both patient clinical factors (i.e. physical function and BPSD) and care partner burden, to optimize care partner mental health outcomes during post-hospital transition.

Objectives: Nearly 75% of persons living with dementia (PLWD) in the US live at home and are cared for by informal family members who have limited access to supportive and accessible services, indicating an increased need for these types of services (Alzheimer's Association, 2023). The Alzheimer's Association call centers offer free telephone care consultations, but it currently remains unclear which types of brief telephone support benefit caregivers. This study compares outcomes of participants who received traditional care consultation calls via the Alzheimer's Association National Helpline with care consultation calls from Helpline staff trained in Solution-Focused Brief Strategies (SFBS), a client-centered evidence- and resource-based approach.

Method: Sequential callers were randomly assigned to the "traditional" or "SFBS" care consultation groups and were assessed at the time of call (baseline) and post-call (T1). The outcomes of interest were general self-efficacy (GSE), self-efficacy in managing emotions (PROMIS), caregiver mastery, therapeutic alliance, and goal setting.

Results: Of over 500 callers, callers receiving the SFBS scored higher on therapeutic alliance and goal-setting metrics, such as greater sense of collaboration on goals (effect size = 0.280, p = 0.0005, significant with Bonferroni correction), mutual agreement with care consultant on goals (effect size = 0.418, p < 0.0001, significant with Bonferroni correction), and believing the way the problem was resolved was correct (effect size = 0.286, p = 0.0007, significant with Bonferroni correction) than those receiving the traditional care consultation. Both groups reported improvements in the PROMIS measure, but there were no differences between groups. There were no significant differences in GSE or caregiver mastery scores between groups.

Conclusion: This study provides evidence for the effectiveness of the integration of SFBS in dementia care consultation calls as part of telephone-based supportive services for dementia caregivers.

Objectives: Depression is one of the main causes of disability worldwide and makes a major contribution to the global disease burden, especially in developing countries. It is also one of the most prevalent psychiatric disorders in the older people and a significant risk factor for both disability and death. Despite the fact that little research has been done on it among those who live in sub-Saharan Africa, especially Ethiopia, the aim of this study was to fill the above-mentioned gap among older people.

Method: A community-based cross-sectional study was conducted from April to June 2023. A total of 607 older people were included using the multistage sampling technique. An interview-administered questionnaire was used to assess depression using the Geriatric Depression Scale item 15 with a cut-off ≥5. For statistical analysis, the binary logistic regression model was employed.

Results: The mean age of the study participants was 72.45 (SD ±9.08) years. The prevalence of depression was found to be 45%. Age 80 years and above, 70-79 years, widowed, retired, known chronic disease, and poor social support were associated factors with depression.

Conclusion: Compared to other studies conducted in different regions of Ethiopia, the prevalence of depression in this study was found to be high, at 45%. The results of this study may be taken as providing health professionals, health policymakers, and other pertinent stakeholders' early warning signs and guidance on how to take efficient control measures and conduct periodic monitoring among older people.

Objectives: To examine how change in benzodiazepine (BZD) use is linked to changes in depressive symptoms intensity, worry intensity, and sleep quality over 16 months.

Method: Data come from a larger randomised controlled trial (RCT) named the 'Programme d'Aide du Succès au SEvrage (PASSE-60+)' study (NCT02281175). Seventy-three participants age 60 years and older took part in a 4-month discontinuation programme and were assessed four times over 16 months. Change in BZD use was defined as the difference in reported mg/day between two assessments. Control variables were RCT discontinuation group; BZD use at T1; and either depressive symptoms, worry intensity, or sleep quality at T1. Hierarchical multiple regressions were used to analyse data.

Results: In the short term, right after the discontinuation programme, sleep quality worsened with lower BZD use. This link was no longer significant at the 3- and 12-month follow-up. In the long term, depressive symptoms lowered with lower BZD use. No change was found in worry intensity in relation to BZD use at all measurement times.

Conclusion: Discontinuation may improve depressive symptoms. Our study also questions the long-term effectiveness of BZD use, since long-term discontinuation was not linked with change in worry intensity and sleep quality.

Objectives: There is a need to improve the provision and reach of community services for people living with dementia, a goal in which community-based support groups can play a key role. The Get Real with Meeting Centres project aimed to explore factors involved in the success and sustainability of Meeting Centres (MCs) a form of community-based support proliferating in the UK. This is the first of two linked articles outlining learning from this realist evaluation of MCs, which focusses on findings around reach and membership.

Method: Semi-structured interviews and focus group discussions were conducted with 77 participants across three case study MC sites in England and Wales, including people living with dementia, informal carers, staff, volunteers, trustees, and supporting professionals/practitioners. Data were themed, then analysed using both soft systems methodology and realist logic of analysis.

Results: Fifty-two 'context-mechanism-outcome' statements were generated, explaining how background circumstances might trigger responses/processes to produce wanted or unwanted outcomes regarding four key areas for MC sustainability: Referrals and the dementia care pathway; Reaching people and membership; Carer engagement and benefit; and Venue and location.

Conclusion: Strong links with formal services and a well-functioning dementia care pathway are essential to sustaining community-based group support such as MCs; group support is also well-placed to assist work to improve pathway issues. Clarity of offer (including benefit to carers), and a wide range of activities, are key to appeal and reach; transport to, and use of, venue are challenges, as are pressures to support people with more advanced dementia.

Objectives: Loneliness is associated with maladaptive cognitions, yet little is known about the association between loneliness and intrusive thinking during older adulthood. Links between loneliness and intrusive thoughts may be particularly strong among individuals with mild cognitive impairment (MCI), who may have greater difficulty regulating emotion and intrusive thoughts. In contrast, having close relationships (e.g. being married) may serve as a protective factor as marital status is associated with better overall well-being.

Method: Participants were 316 older adults (recruited from the Bronx, NY, as part of a larger study) without dementia at study intake (40% Black; 13% Hispanic, M_age = 77.45 years, 67% women) who completed ecological momentary assessments five times daily for 14 consecutive days (13,957 EMAs total). Multilevel modeling was used to examine the association between momentary loneliness and intrusive thoughts and whether MCI and marital status interacted to moderate this association.

Results: There was a significant three-way interaction (β = -0.17, p < 0.05), such that lagged momentary loneliness was positively associated with intrusive thoughts (3-4 h later) for those with MCI who were not married.

Conclusion: Findings suggest that among older adults with MCI, being married may be a protective factor and being unmarried may be a risk factor for experiencing loneliness and subsequent intrusive thoughts.

Objectives: Loneliness has been associated with psychotic-like experiences (PLEs) in the general population, but the mechanisms underlying this association are poorly understood. Theoretical models, corroborated by empirical findings, signify the key role of biased cognition in both loneliness and psychosis. This study tested whether two cognitive biases - Selective Attention to Threat (ATB) and External Attribution Bias (EAB) - account for the association between loneliness and PLEs.

Method: A convenience sample (n = 357) of middle-aged and older adults (aged 40+) was recruited online from the UK population. The parallel mediation model with two the aforementioned cognitive biases as mediators was tested.

Results: A mediation effect between loneliness and PLEs via ATB (ab₁ = 0.441, 95% CI = [0.264, 0.646]) and EAB (ab₂ = 0.354, 95% CI [0.124, 0.627] was established. This model remained significant after controlling for the current symptoms of anxiety and depression.

Conclusion: Greater loneliness was associated with a higher rate of PLEs in the sample of middle-aged and older adults. This association was fully explained by ATB and EAB, independent of the current symptoms of anxiety and depression.

Objectives: This study explores the preferences and willingness-to-pay (WTP) of carers for Meeting Centres (MCs) attributes in assisting individuals with mild to moderate dementia.

Method: Preferences from 108 carers, gathered through UK-wide MC networks, were collected using a Discrete Choice Experiment survey. The survey incorporated attributes derived from evidence synthesis and lay consultation. A regression model estimated preference weights and marginal WTP for a change in attributes one a time within the MC support 'package.'

Results: Carers preferred MCs offering a balanced mix of practical activities and emotional support, along with flexibility without booking requirements and low costs. Social opportunities and the frequency of the meeting were not prioritised. Respondents expressed a WTP of £43 to stay with 'My MC,' the preferred option, compared to transitioning to an alternative in-person MC, all else being equal. Various factors, including attendance modality, the relationship with the supported person, age, and gender, influenced carers' choices.

Conclusion: These findings offer valuable insights into carers' preferences, priorities, and WTP within MC support for those with mild to moderate dementia. Understanding these factors can guide the implementation and sustainability of MCs, ensuring alignment with carers' needs and preferences and, ultimately, enhancing support for individuals with dementia.
