This study investigated attitudes towards dementia among Chinese immigrants aged 50 years and over living in Australia and compares these attitudes with those of individuals living in mainland China. It aimed to better understand what older Chinese adults think about dementia and to inform the development of tailored dementia-related services for this group of people.

A qualitative design involving individual interviews was employed in this study.

Forty-six participants were recruited: 21 in Melbourne and 25 in Beijing. All interviewees were born in mainland China, were community-dwelling, and did not have a dementia diagnosis.

The tripartite model of attitudes was used to guide the semi-structured interview design and report the results. Thematic qualitative analysis was employed.

In both groups, most participants held negative feelings, stigmatized views and negative stereotypes of dementia. However, most participants expressed a willingness to help individuals living with dementia. Regarding dementia care, nearly all participants preferred home care but thought formal care would become the mainstream form of care in the future. Fewer Melbourne participants expressed concerns regarding developing dementia, were interested in dementia, or perceived a need for dementia-related educational activities. Melbourne participants also reported more avoidant responses to dementia or individuals living with dementia.

This study carefully compares attitudes towards dementia between older Chinese immigrants in Melbourne and older Chinese adults in Beijing. Similarities and differences were observed between these two groups. Dementia-related service providers should consider the sociocultural changes and migration-related barriers experienced by Chinese immigrants.

Prospective studies suggest that memory deficits are detectable decades before clinical symptoms of dementia emerge. However, individual differences in long-term memory trajectories prior to diagnosis need to be further elucidated. The aim of the current study was to investigate long-term dementia and mortality risk for individuals with different memory trajectory profiles in a well-characterized population-based sample.

1062 adults (aged 45–80 years) who were non-demented at baseline were followed over 23–28 years. Dementia and mortality risk were studied for three previously classified episodic memory trajectory groups: maintained high performance (Maintainers; 26%), average decline (Averages; 64%), and accelerated decline (Decliners; 12%), using multistate modeling to characterize individuals’ transitions from an initial non-demented state, possibly to a state of dementia and/or death.

The memory groups showed considerable intergroup variability in memory profiles, starting 10–15 years prior to dementia diagnosis, and prior to death. A strong relationship between memory trajectory group and dementia risk was found. Specifically, Decliners had more than a fourfold risk of developing dementia compared to Averages. In contrast, Maintainers had a 2.6 times decreased dementia risk compared to Averages, and in addition showed no detectable memory decline prior to dementia diagnosis. A similar pattern of association was found for the memory groups and mortality risk, although only among non-demented.

There was a strong relationship between accelerated memory decline and dementia, further supporting the prognostic value of memory decline. The intergroup differences, however, suggest that mechanisms involved in successful memory aging may delay symptom onset.

(1) To delineate whether cognitive flexibility and inhibitory ability are neurocognitive markers of passive suicidal ideation (PSI), an early stage of suicide risk in depression and (2) to determine whether PSI is associated with volumetric differences in regions of the prefrontal cortex (PFC) in middle-aged and older adults with depression.

Cross-sectional study.

University medical school.

Forty community-dwelling middle-aged and older adults with depression from a larger study of depression and anxiety (NIMH R01 MH091342-05 PI: O’Hara).

Psychiatric measures were assessed for the presence of a DSM-5 depressive disorder and PSI. A neurocognitive battery assessed cognitive flexibility, inhibitory ability, as well as other neurocognitive domains.

The PSI group (n = 18) performed significantly worse on cognitive flexibility and inhibitory ability, but not on other neurocognitive tasks, compared to the group without PSI (n = 22). The group with PSI had larger left mid-frontal gyri (MFG) than the no-PSI group. There was no association between cognitive flexibility/inhibitory ability and left MFG volume.

Findings implicate a neurocognitive signature of PSI: poorer cognitive flexibility and poor inhibitory ability not better accounted for by other domains of cognitive dysfunction and not associated with volumetric differences in the left MFG. This suggests that there are two specific but independent risk factors of PSI in middle- and older-aged adults.

To explore and compare the experiences of care home visits during the pandemic in the UK and the Netherlands.

Qualitative semi-structured interview studies

Family carers of relatives residing in care homes in the UK and the Netherlands were interviewed remotely.

Family carers were asked about their experiences of care home visits during the pandemic, and specifically in the Netherlands after care homes had reopened. Transcripts were analyzed in each country separately in the native language using thematic analysis, before discussing findings at multiple analysis meetings.

Across 125 interviews, we developed four themes: (1) different types of contact during lockdown; (2) deterioration of resident health and well-being; (3) emotional distress of both visitors and residents; and (4) compliance to guidelines and regulations. Visiting in both the UK and the Netherlands was beneficial, if possible in the UK, yet was characterized by alternative forms of face-to-face visits which was emotionally distressing for many family carers and residents. In the Netherlands, government guidance did enable early care home visitation, while the UK was lacking any guidance leading to care homes implementing restrictions differently.

Early and clear guidance, as well as communication, is required in future pandemics, and in this ongoing pandemic, to enable care home visits between residents and loved ones. It is important to take learnings from this global pandemic to reimagine long-term care, highlighting the value of socializing for care home residents.

Indigenous Australians experience higher levels of psychological distress compared to the general population. Physical activity is a culturally acceptable approach, associated with reduction of depressive symptoms. The protective properties of physical activity for depressive symptoms are yet to be evaluated in older Indigenous Australians.

A two-phase study design comprised of a qualitative thematic analysis following a quantitative regression and moderation analysis.

Firstly, a total of 336 Indigenous Australians aged 60 years and over from five NSW areas participated in assessments on mental health, physical activity participation, and childhood trauma. Secondly, a focus group of seven Indigenous Australians was conducted to evaluate barriers and facilitators to physical activity.

Regression and moderation analyses examined links between depression, childhood trauma, and physical activity. Thematic analysis was conducted exploring facilitators and barriers to physical activity following the focus group.

Childhood trauma severity and intensity of physical activity predicted depressive symptoms. Physical activity did not affect the strength of the relationship between childhood trauma and depression. Family support and low impact activities facilitated commitment to physical activity. In contrast, poor mental health, trauma, and illness acted as barriers.

Physical activity is an appropriate approach for reducing depressive symptoms and integral in maintaining health and quality of life. While situational factors, health problems and trauma impact physical activity, accessing low-impact group activities with social support was identified to help navigate these barriers.

Geriatric depression (GD) is associated with significant medical comorbidity, cognitive impairment, brain atrophy, premature mortality, and suboptimal treatment response. While apathy and anxiety are common comorbidities, resilience is a protective factor. Understanding the relationships between brain morphometry, depression, and resilience in GD could inform clinical treatment. Only few studies have addressed gray matter volume (GMV) associations with mood and resilience.

Forty-nine adults aged >60 years (38 women) with major depressive disorder undergoing concurrent antidepressant treatment participated in the study.

Anatomical T1-weighted scans, apathy, anxiety, and resilience data were collected. Freesurfer 6.0 was used to preprocess T1-weighted images and qdec to perform voxel-wise whole-brain analyses. Partial Spearman correlations controlling for age and sex tested the associations between clinical scores, and general linear models identified clusters of associations between GMV and clinical scores, with age and sex as covariates. Cluster correction and Monte-Carlo simulations were applied (corrected alpha = 0.05).

Greater depression severity was associated with greater anxiety (r = 0.53, p = 0.0001), lower resilience (r = −0.33, p = 0.03), and greater apathy (r = 0.39, p = 0.01). Greater GMV in widespread, partially overlapping clusters across the brain was associated with reduced anxiety and apathy, as well as increased resilience.

Our results suggest that greater GMV in extended brain regions is a potential marker for resilience in GD, while GMV in more focal and overlapping regions may be markers for depression and anxiety. Interventions focused on improving symptoms in GD may seek to examine their effects on these brain regions.

Ageism is defined as stereotypes, prejudice, and discrimination towards people because of their age. Although ageism can be directed towards people of any age group, most research has focused on ageism towards older people. Ageism towards older people is known to have a significant impact on their health and wellbeing and to even result in higher healthcare costs. The present study evaluated the use of virtual embodiment (VE) to reduce self- and other-directed ageism.

We randomized 80 individuals between the ages of 18 and 35 years to one of two conditions: VE as an older or a younger avatar.

No differences were found on explicit measures of ageism. Once multiple comparisons were accounted for, a nonsignificant reduction in implicit age bias following exposure to the older avatar (Cohen’s d = .75, p = .02) also was found.

Past research has established the effectiveness of VE in relation to implicit measures. However, once both explicit and implicit measures are included and multiple comparisons are accounted for, neither explicit nor implicit measures of ageism show a significant effect. Given the multidimensional nature of ageism, further research is needed to establish the effectiveness of VE once multiple measures of ageism are considered.

Studies have shown that when people grow older, the negative perceptions about age(ing) become self-directed. In this study, we examined if and how this assertion is expressed in the self-presentation of older adults.

To explore this issue, we undertook an online survey with 818 Israeli older adults (aged 65–90) who were asked to present themselves in writing, using an open question and to choose the age terms that they preferred, relying on a multiple-choice question. Responses were analyzed qualitatively and quantitatively using “word cloud” and linguistic inquiry.

The analysis indicated three ways of coping with the issue of age in one’s self-presentation: Absence of old age – older people who blur their processes of aging; Camouflaged aging – older people who emphasize their age by using a line of self-ageism; Multiplicity of old age terms – the existing gap between what is being used by people and the ideal related to the use of existing age terms. The findings highlight the role of subjective age in one’s self-presentations.

The results point to the ambivalence that older people feel in relation to their age(ing) and especially reflect the paradox of subjective age. That is, on the one hand studies have stressed the positive aspects of this practice, whereas on the other hand, subjective age possibly reflects a response to internalized negative stereotypes and prejudice about old age(ing). In this sense, this study expands the knowledge in the field of self-presentation and (subjective) age in the second half of life.

To user-test a recovery-oriented, clinician-facilitated, web-based, self-management intervention accessible via mobile device: ROAD MAP. The initial programme theory underlying this research is that supporting the experiences of CHIME (connectedness, hope and optimism, identity, meaning in life and empowerment), in persons living with dementia (PLWD) will have health-promoting benefits for the PLWD.

The intervention will be delivered to 20 dyads of community-dwelling PLWDs and their carers via a five-week, online, recovery-based curriculum. Five convenience-sampled occupational therapists (OT) will be trained online in a 10-hour training programme to deliver the intervention. All data collection instruments are informed by realist evaluation (RE) methodology and enquire into initial programme theories (IPTs) used to develop the curriculum and the ROAD MAP digital tool. Data collection, between January and March 2023, will occur during both the OT training and the five-week pilot study. The OT facilitators will provide qualitative feedback on the ROAD MAP technology. Data will be collected via pre-post self-completion forms, semi-structured interviews, a focus group, and weekly guided reflective journal. PLWD’s self-reported, user experience will be live polled within the weekly one-hour long sessions of the pilot. Their digital usage analytics will be generated by the MyGuide platform on which the ROAD MAP intervention is built. These data will be manually screened for IPT relevance and used to test emerging programme theories.

All data will be collected by end of March 2023 and analysed by end of May 2023. NVivo will be used to generate refined programme theories according to RE methodology. This will provide evidence of plausible, causal context-mechanism-outcome configurations which may optimize the refined version of the ROAD MAP digital intervention, curriculum and facilitator training methods.

This study will increase knowledge of a methodology for developing useable and acceptable recovery-oriented telehealth tools for PLWD. This intervention could directly enhance the education of health care professionals and improve the equitable delivery of dementia services.

To examine the bidirectional associations between older adult spouses’ cognitive functioning and depressive symptoms over time and replicate previous findings from the United States (US) in Mexico.

Longitudinal, dyadic path analysis with the actor-partner interdependence model.

Data were from the three most recent interview waves (2012, 2015, and 2018) of the Mexican Health and Aging Study (MHAS), a longitudinal national study of adults aged 50+ years in Mexico.

Husbands and wives from 905 community-dwelling married couples (N = 1,810).

The MHAS cognitive battery measured cognitive function. Depressive symptoms were assessed using a modified nine-item Center for Epidemiologic Studies Depression Scale. Baseline covariates included age, education, number of children, limitation with any activity of daily living, limitation with any instrumental activity of daily living, and pain.

As hypothesized, there were significant within-individual associations in which one person’s own cognitive functioning and own depressive symptoms predicted their own follow-up cognitive functioning and depressive symptoms, respectively. In addition, a person’s own cognitive functioning predicted their own depressive symptoms, and a person’s own depressive symptoms predicted their own cognitive functioning over time. As hypothesized, there was a significant partner association such that one person’s depressive symptoms predicted more depressive symptoms in the partner.

Findings from this study of older Mexican couples replicates findings from studies of older couples in the US, showing that depressive symptoms in one partner predict depressive symptoms in the other partner over time; however, there was no evidence for cognition–depression partner associations over time.

This study examined the change in dementia literacy and dementia worry over a 5-year span among older Chinese Americans living in Arizona.

This study used survey data collected among a purposive sample of 703 community-dwelling Chinese Americans aged 55 years or older living in the metropolitan areas of Phoenix, Arizona, from 2013 to 2017. The average age of participants was 73.1 (SD = 8.7) and 64.2% were female. Dementia literacy was measured by dementia knowledge (knowledge about Alzheimer’s disease and related dementia) and dementia beliefs (biased attitude toward dementia). Dementia worry was measured by assessing participants’ fear toward and concerns of developing dementia.

Regression analyses found dementia knowledge decreased (p < 0.05) and dementia beliefs remained unchanged (p > 0.05) from 2013 to 2017 among participants. Dementia worry only increased among those who lived alone. Significant correlates of dementia worry included low formal education level, depressive symptoms, and family conflict.

Public health education targeting older Chinese Americans should aim to enhance dementia knowledge and to rectify their biased attitudes toward dementia. Psychosocial education or counseling should be available to older Chinese Americans who present dementia worry, particularly for those who live alone. More studies using diverse study designs, such as a longitudinal design, are needed to examine change in dementia literacy and worry among this population.

We examined whether preadmission history of depression is associated with less delirium/coma-free (DCF) days, worse 1-year depression severity and cognitive impairment.

A health proxy reported history of depression. Separate models examined the effect of preadmission history of depression on: (a) intensive care unit (ICU) course, measured as DCF days; (b) depression symptom severity at 3 and 12 months, measured by the Beck Depression Inventory-II (BDI-II); and (c) cognitive performance at 3 and 12 months, measured by the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) global score.

Patients admitted to the medical/surgical ICU services were eligible.

Of 821 subjects eligible at enrollment, 261 (33%) had preadmission history of depression. After adjusting for covariates, preadmission history of depression was not associated with less DCF days (OR 0.78, 95% CI, 0.59–1.03 p = 0.077). A prior history of depression was associated with higher BDI-II scores at 3 and 12 months (3 months OR 2.15, 95% CI, 1.42–3.24 p = <0.001; 12 months OR 1.89, 95% CI, 1.24–2.87 p = 0.003). We did not observe an association between preadmission history of depression and cognitive performance at either 3 or 12 months (3 months beta coefficient −0.04, 95% CI, −2.70–2.62 p = 0.97; 12 months 1.5, 95% CI, −1.26–4.26 p = 0.28).

Patients with a depression history prior to ICU stay exhibit a greater severity of depressive symptoms in the year after hospitalization.

To investigate the relationship between lean muscle mass and treatment response in treatment-resistant late-life depression (TR-LLD). We hypothesized that lower lean muscle mass would be associated with older age, higher physical comorbidities, higher depressive symptom severity, and poorer treatment response.

Secondary analysis of a randomized, placebo-controlled trial.

Three academic hospitals in the United States and Canada.

Adults aged 60+ years with major depressive disorder who did not remit following open treatment with venlafaxine extended-release (XR) (n = 178).

We estimated lean muscle mass using dual-energy X-ray absorptiometry (DEXA) scans prior to and following randomized treatment with aripiprazole or placebo added to venlafaxine XR. Multivariate regressions estimated influence of demographic and clinical factors on baseline lean muscle mass, and whether baseline lean muscle mass was associated with treatment response, adjusted for treatment arm.

Low lean muscle mass was present in 22 (12.4%) participants. Older age and female sex, but not depressive symptom severity, were independently associated with lower lean muscle mass at baseline. Marital status, baseline depressive symptom severity, and treatment group were associated with improvement of depressive symptoms in the randomized treatment phase. Baseline lean muscle mass was not associated with improvement, regardless of treatment group.

As expected, older age and female sex were associated with lower lean muscle mass in TR-LLD. However, contrary to prior results in LLD, lean muscle mass was not associated with depression severity or outcome. This suggests that aripiprazole augmentation may be useful for TR-LLD, even in the presence of anomalous body composition.

To investigate the nature of the relationship between cognitive function, mood state, and functionality in predicting awareness in a non-clinically depressed sample of participants with mild to moderate Alzheimer’s disease (AD) in Brazil.

People with AD (PwAD) aged 60 years or older were recruited from an outpatient unit at the Center of AD of the Federal University of Rio de Janeiro, Brazil. Measures of awareness of condition (Assessment Scale of the Psychosocial Impact of the Diagnosis of Dementia), cognitive function (Mini-Mental State Examination), mood state (Cornell Scale for Depression in Dementia), and functionality (Pfeffer Functional Activities Questionnaire) were applied to 264 people with mild to moderate AD and their caregivers. Hypotheses were tested statistically using SEM approach. Three competing models were compared.

The first model, in which the influence of mood state and cognitive function on awareness was mediated by functionality, showed a very good fit to the data and a medium effect size. The competing models, in which the mediating variables were mood state and cognitive function, respectively, only showed poor model fit.

Our model supports the notion that the relationship between different factors and awareness in AD is mediated by functionality and not by depressive mood state or cognitive level. The proposed direct and indirect effects on awareness are discussed, as well as the missing direct influence of mood state on awareness. The understanding of awareness in dementia is crucial and our model gives one possible explanation of its underlying structure in AD.

Behavioral and psychological symptoms of dementia (BPSD) are a group of noncognitive symptoms that occur commonly among individuals with dementia. These symptoms worsen the morbidity and mortality among individuals with dementia and significantly increase the cost of caring for these individuals. Transcranial magnetic stimulation (TMS) has been shown to have some benefits in the treatment of BPSD. This review provides an updated summary of the effect of TMS on BPSD.

We conducted a systematic review of PubMed, Cochrane, and Ovid databases on the use of TMS to treat BPSD.

We found 11 randomized controlled studies that evaluated the use of TMS among individuals with BPSD. Three of these studies examined the effect of TMS on apathy, two of which showed significant benefit. Seven studies showed that TMS significantly improves BPSD: six using repetitive transcranial magnetic stimulation (rTMS) and one using transcranial direct current stimulation (tDCS). Four studies, two evaluating tDCS, one evaluating rTMS, and one evaluating intermittent theta-burst stimulation (iTBS) showed a nonsignificant impact of TMS on BPSD. Adverse events were predominantly mild and transitory in all studies.

Available data from this review indicate that rTMS is beneficial for individuals with BPSD, especially among individuals with apathy, and is well tolerated. However, more data are needed to prove the efficacy of tDCS and iTBS. Additionally, more randomized controlled trials with longer treatment follow-up and standardized use of BPSD assessments are needed to determine the best dose, duration, and modality for effective treatment of BPSD.
