The onset of Alzheimer's disease (AD) affects couples’ relationship. We investigated the perception of change and sexual satisfaction in spouse-caregivers and their partners diagnosed with AD.

We compared 74 dyads of people with Alzheimer's disease (PwAD)/spouse-caregivers and 21 elderly dyads control. We assessed sexual satisfaction with Questionnaire on Sexual Experience and Satisfaction (QSES), cognition using a Mini-Mental State Examination (MMSE), disease severity using a Clinical Dementia Rating scale (CDR), awareness of disease with Assessment Scale of Psychosocial Impact of the Diagnosis of Dementia (ASPIDD), functionality with Pfeffer Functional Activities Questionnaire (FAQ), depressive symptoms with Cornell Scale for Depression in Dementia (CSDD), quality of life using a Quality of Life in Alzheimer's Disease Scale (QoL-AD), and burden using a Zarit Burden Interview (ZBI).

We found differences between the perception and no perception of change in sexual activity of PwAD (p < 0.001), spouse-caregivers (p < 0.01), and controls (p < 0.05). Moderate to severe sexual dissatisfaction was observed in 36.5% of PwAD, 65% of spouse-caregivers, and 31% of controls. PwAD sexual satisfaction was related to cognitive impairment (p < 0.05). Spouse-caregivers sexual satisfaction was related to gender (p < 0.05) and the presence of sexual activity (p < 0.001).

The perception of change with higher sexual dissatisfaction, were significant in PwAD and their spouse-caregivers, in comparison with couples of elderly without dementia.

Up to half of people with dementia in high income countries live in nursing homes and more than two-thirds of care home residents have dementia. Fewer than half of these residents report good quality of life and most older people are anxious about the prospect of moving into a nursing home. Robust evidence is needed as to the causes of admission to nursing homes, particularly where these risk factors are modifiable.

We conducted a systematic literature search to identify controlled comparison studies in which the primary outcome was admission to nursing home of older adults with dementia. Identified studies were assessed for validity and 26 (17 cohort and 9 case-control) were included. Qualitative and quantitative analyses were conducted, including meta-analysis of 15 studies.

Poorer cognition and behavioral and psychological symptoms of dementia (BPSD) were consistently associated with an increased risk of nursing home admission and most of our meta-analyses demonstrated impairments in activities of daily living as a significant risk. The effects of community support services were unclear, with both high and low levels of service use leading to nursing home placement. There was an association between caregiver burden and risk of institutionalization, but findings with regard to caregiver depression varied, as did physical health associations, with some studies showing an increased risk of nursing home placement following hip fracture, reduced mobility, and multiple comorbidities.

We recommend focusing on cognitive enhancement strategies, assessment and management of BPSD, and carer education and support to delay nursing home placement.

Depression in nursing facilities is widespread and has been historically under-recognized and inadequately treated. Many interventions have targeted depression among residents with dementia in these settings. Less is known about depression treatment in residents without dementia who may be more likely to return to community living. Our study aimed to systematically evaluate randomized control trials (RCTs) in nursing facilities that targeted depression within samples largely comprised of residents without dementia.

The following databases were evaluated with searches covering January 1991 to December 2015 (PubMed, PsycINFO) and March 2016 (CINAHL). We also examined national and international clinical trial registries including ClinicalTrials.gov. RCTs were included if they were published in English, evaluated depression or depressive symptoms as primary or secondary outcomes, and included a sample with a mean age of 65 years and over for which most had no or only mild cognitive impairment.

A total of 32 RCTs met our criteria including those testing psychotherapeutic interventions (n=13), psychosocial and recreation interventions (n=9), and pharmacologic or other biologic interventions (n=10). Seven psychotherapeutic, six psychosocial and recreation, and four pharmacologic or other biologic interventions demonstrated a treatment benefit.

Many studies had small samples, were of poor methodological quality, and did not select for depressed residents. There is limited evidence suggesting that cognitive behavioral therapies, reminiscence, interventions to reduce social isolation, and exercise-based interventions have some promise for decreasing depression in cognitively intact nursing home residents; little can be concluded from the pharmacologic or other biologic RCTs.

Personality may predispose family caregivers to experience caregiving differently in similar situations and influence the outcomes of caregiving. A limited body of research has examined the role of some personality traits for health-related quality of life (HRQoL) among family caregivers of persons with dementia (PWD) in relation to burden and depression.

Data from a large clinic-based national study in South Korea, the Caregivers of Alzheimer's Disease Research (CARE), were analyzed (N = 476). Path analysis was performed to explore the association between family caregivers’ personality traits and HRQoL. With depression and burden as mediating factors, direct and indirect associations between five personality traits and HRQoL of family caregivers were examined.

Results demonstrated the mediating role of caregiver burden and depression in linking two personality traits (neuroticism and extraversion) and HRQoL. Neuroticism and extraversion directly and indirectly influenced the mental HRQoL of caregivers. Neuroticism and extraversion only indirectly influenced their physical HRQoL. Neuroticism increased the caregiver's depression, whereas extraversion decreased it. Neuroticism only was mediated by burden to influence depression and mental and physical HRQoL.

Personality traits can influence caregiving outcomes and be viewed as an individual resource of the caregiver. A family caregiver's personality characteristics need to be assessed for tailoring support programs to get the optimal benefits from caregiver interventions.

Caring for someone with Alzheimer's disease (AD) is very challenging. Social support may play a crucial role in helping caregivers to adapt better to their caregiving role. The aim of this study is to explore the role of social support as a moderator variable of the relationship between depression and life satisfaction in caregivers for patients with AD in Saudi Arabia.

In this cross-sectional study, 122 caregivers for patients with AD completed questionnaires assessing informal social support, depressive symptoms, and general life satisfaction.

The demographic characteristics showed that 79% (n = 96) of caregivers were females and between the ages of 20 and 50. Higher levels of social support positively correlated with reported higher levels of life satisfaction (r = 0.483, p < 0.001). Depression was negatively correlated with social support (r = −0.418, p < 0.001) and life satisfaction scores (r = −0.553, p = < 0.001). Social support was found to be a partial mediator variable, mediating approximately 23.05% of the total effect of depression on life satisfaction (Sobel = −3.065, p = 0.002).

Informal social support can act as a mediator variable in the relationship of depression and life satisfaction in caregivers of AD patients. Improving the informal social support networks may help in coping with caregiving burden and better quality of life.

It is unclear whether health service use influences the association between psychiatric and physical co-morbidity and suicide risk in older adults.

Controls were older adults (n = 2,494) participating in a longitudinal study on the health of the elderly carried out between 2004 and 2007, in Quebec. The cases were all suicide decedents (n = 493) between 2004 and 2007, confirmed by the Quebec Coroner's office. Multivariate analyses were carried out to test the association between suicide and the presence of psychiatric and physical illnesses controlling for health service use and socio-demographic factors by gender and age group. Interaction terms were also tested between suicide and co-morbidity on outpatient service use.

The presence of physical illnesses only, was associated with a reduced risk of suicide across all sex and age groups. The presence of a mental disorder only was associated with an increased risk of suicide overall and specifically in females and those aged 70 to 84 years of age. Suicide risk was lower in those with a psychiatric and physical co-morbidity and consulting mental health services.

Increased mental health follow-up in older adults with psychiatric illnesses is needed for the detection of suicidal behavior and reducing suicide risk in males. Further research should focus on the mitigating effect of the presence of physical illnesses on stigma and health service use and the presence of social support in the elderly.

Anxiety disorders are prevalent yet under-recognized in late life. We examined the prevalence of anxiety disorders in a representative sample of community dwelling older adults in Hong Kong.

Data on 1,158 non-demented respondents aged 60–75 years were extracted from the Hong Kong Mental Morbidity survey (HKMMS). Anxiety was assessed with the revised Clinical Interview Schedule (CIS-R).

One hundred and thirty-seven respondents (11.9%, 95% CI = 10–13.7%) had common mental disorders with a CIS-R score of 12 or above. 8% (95% CI = 6.5–9.6%) had anxiety, 2.2% (95% CI = 1.3–3%) had an anxiety disorder comorbid with depressive disorder, and 1.7% (95% CI = 1–2.5%) had depression. Anxious individuals were more likely to be females (χ2 = 25.3, p < 0.001), had higher chronic physical burden (t = −9.3, p < 0.001), lower SF-12 physical functioning score (t = 9.2, p < 0.001), and poorer delayed recall (t = 2.3, p = 0.022). The risk of anxiety was higher for females (OR 2.8, 95% C.I. 1.7–4.6, p < 0.001) and those with physical illnesses (OR 1.4, 95% C.I. 1.3–1.6, p < 0.001). The risk of anxiety disorders increased in those with disorders of cardiovascular (OR 1.9, 95% C.I. 1.2–2.9, p = 0.003), musculoskeletal (OR 2.0, 95% C.I. 1.5–2.7, p < 0.001), and genitourinary system (OR 2.0, 95% C.I. 1.3–3.2, p = 0.002).

The prevalence of anxiety disorders in Hong Kong older population was 8%. Female gender and those with poor physical health were at a greater risk of developing anxiety disorders. Our findings also suggested potential risk for early sign of memory impairment in cognitively healthy individuals with anxiety disorders.

Existing literature suggests that mental health literacy is positively associated with mental health services utilization. Despite an aging population that faces significant mental health concerns in Korea, the role of mental health literacy on mental health services utilization is not known among older adults in Korea. This study aimed to (1) identify whether mental health literacy mediates the association between population characteristics and mental health services utilization and (2) identify an optimal path model for mental health services utilization among Korean older adults.

Using a cross-sectional survey with a quota sampling strategy, we collected and analyzed responses from 596 community-dwelling individuals ages 65 years and older. We used structural equation modeling (SEM) to estimate the effect of mental health literacy as a mediator.

When controlling for other relevant covariates in the optimal path model, mental health literacy mediated the relationships between three socio-demographic factors (education, general literacy, and health status) and mental health services utilization. The model fit index shows that the SEM fits very well (CFI = 0.92, NFI = 0.90, RMSEA = 0.07).

Efforts to improve mental health literacy through community-based education programs may need to particularly target Korean older adults with the relevant socio-demographic characteristics to enhance their utilization of appropriate mental health services.

This study was aimed toward discerning depressive symptom trajectories associated with different chronic conditions and toward finding modifiable factors associated with those trajectories.

Data were drawn from the 1996–2007 Taiwan Longitudinal Study on Aging. Nine chronic conditions were selected, and mood trajectories were measured with the Center of Epidemiological Studies-Depression scale.

Among the nine chronic conditions we examined, four patterns of depressive symptom trajectories were identified: (1) elevated depressive symptoms and worsened over time after diagnosed with heart disease (n = 681), arthritis (n = 850), or hypertension (n = 1,207); (2) elevated depressive symptoms without worsening over time after diagnosed with stroke (n = 160), lung diseases (n = 432), gastric conditions (n = 691), or liver diseases (n = 234); (3) no elevated depressive symptoms after diagnosis but an increase in depressive symptoms over time for participants with diabetes (n = 499); and (4) no significant patterns after diagnosed with cancer (n = 57). Cumulative psychological burden over time was significant for participants with hypertension, diabetes, heart diseases, or arthritis. However, these effects disappeared after controlling for comorbidities and physical limitations. Moreover, psychiatric condition was found to play an important role in baseline depressive symptoms among participants diagnosed with lung diseases, arthritis, or liver diseases.

Findings from this study provide information in addressing psychological burden at different times for different conditions. In addition, minimizing the incidence of comorbidities, physical limitations, or psychiatric conditions may have the prospective effect of avoiding the trend of increased depressive symptoms, especially when adults diagnosed with hypertension, diabetes, heart diseases, arthritis, lung diseases, arthritis, or liver diseases.

Anosognosia is a common feature in Alzheimer's disease (AD). The brain substrates of anosognosia are not fully understood, and less is known about the cognitive substrates of anosognosia in prodromal and early stages of AD.

Fourty-seven patients with amnestic-type mild cognitive impairment (aMCI) (n = 26) and early-stage AD (n = 21) were included, and Clinical Insight Rating Scale and Anosognosia Questionnaire for Dementia (AQ-D) were used to assess anosognosia. A detailed neuropsychological battery was administered; each patient underwent a structural magnetic resonance imaging (MRI). Correlation between anosognosia and performance in individual cognitive domains as well as correlation between anosognosia and cortical thickness values in regions of interest were assessed.

Performance of the anosognosic patients in Digit Ordering Test (DOT), Digit Span Backwards, and Clock Drawing Test (CDT) was significantly worse compared to non-anosognosic patients in the total study population and in the aMCI subgroup but not in AD group. AQ-D scores negatively correlated with Mini-Mental State Examination (MMSE), California Verbal Learning Test (CVLT), Digit Span Backwards and CDT scores in total group and MMSE, CVLT, DOT, and Digit Span Backwards scores in the aMCI group. No significant correlations were found between cortical thickness measurements and AQ-D scores in any of the patient populations.

Anosognosia was associated with episodic memory, working memory, and executive functions in the total population and aMCI group, but no association was found in early-stage AD patients. Anosognosia in the early stages of AD may be related with non-structural changes such as hypoconnectivity rather than structural changes.

There is a growing recognition of the need to make the built environment in towns and cities more enabling for people with dementia. This study reports the development of a reliable tool to assess the support provided to people with dementia by public and commercial buildings such as council offices, supermarkets, banks, and medical centers as they approach, use, and leave them.

A three-step process was carried out to develop and establish the reliability of the tool: (1) a review of principles and available tools informed the development and modification of an environmental audit tool of proven utility, (2) the draft tool was subjected to an iterative process of evaluation by a team of people with expertise in design and town planning, people with dementia and their carers, (3) inter-rater reliability and internal consistency were assessed on a sample of 60 public and commercial buildings.

The review of available tools led to the drafting of a tool that was refined through iterative, experience-based evaluation resulting in a tool that has high inter-rater reliability and internal validity. The data gathered enabled a sample of banks, libraries, shops, medical facilities, supermarkets and council offices to be compared.

The new tool aids the collection of reliable information on the strengths and weaknesses of public and commercial buildings. This information is likely to be of use in the refurbishment of these buildings to improve their support of people with dementia as they use them in their daily life.

In a previous paper, we presented results from a 12-week study of a Psychomotor DANCe Therapy INtervention (DANCIN) based on Danzón Latin Ballroom that involves motor, emotional-affective, and cognitive domains, using a multiple-baseline single-case design in three care homes. This paper reports the results of a complementary process evaluation to elicit the attitudes and beliefs of home care staff, participating residents, and family members with the aim of refining the content of DANCIN in dementia care.

An external researcher collected bespoke questionnaires from ten participating residents, 32 care home staff, and three participants’ family members who provided impromptu feedback in one of the care homes. The Behavior Change Technique Taxonomy v1 (BCTTv1) provided a methodological tool for identifying active components of the DANCIN approach warranting further exploration, development, and implementation.

Ten residents found DANCIN beneficial in terms of mood and socialization in the care home. Overall, 78% of the staff thought DANCIN led to improvements in residents’ mood; 75% agreed that there were improvements in behavior; 56% reported increased job satisfaction; 78% of staff were enthusiastic about receiving further training. Based on participants’ responses, four BCTTv1 labels–Social support (emotional), Focus on past success and verbal persuasion to boost self-efficacy, Restructuring the social environment and Habit formation–were identified to describe the intervention. Residents and staff recommended including additional musical genres and extending the session length. Discussions of implementing a supervision system to sustain DANCIN regularly regardless of management or staff turnover were suggested.

Care home residents with mild to moderate dementia wanted to continue DANCIN as part of their routine care and staff and family members were largely supportive of this approach. This study argues in favor of further dissemination of DANCIN in care homes. We provide recommendations for the future development of DANCIN based on the views of key stakeholder groups.

Several studies on the effect of physical exercise on activities of daily living (ADL) for people with dementia exist; yet, data concerning the specific context of acute psychiatric hospitals remain scant. This study measured the effect of a physical exercise program on ADL scores in patients with moderate to severe dementia hospitalized in an acute psychiatric ward.

A multicenter clinical trial was conducted in five Swiss and Belgian psychiatric hospitals. Participants were randomly allocated to either an experimental group (EG) or a control group (CG). Members of the EG received 20 physical exercise sessions (strengthening, balance, and walking) over a four-week period while members of the CG participated in social interaction sessions of equivalent duration and frequency, but without physical exercise. The effect of exercise on ADL was measured by comparing scores of the Barthel Index and the Functional Independence Measure in the EG and CG before and after the intervention, and two weeks later.

Hundred and sixty patients completed the program. Characteristics of participants of both groups were similar at the inception of the study. The mean ADL score of EG decreased slightly over time, whereas that of the CG significantly decreased compared to initial scores. Overall differences between groups were not significant; however, significant differences were found for mobility-related items.

ADL scores in elderly with moderate to severe dementia deteriorate during acute psychiatric hospitalization. An exercise program delays the loss of mobility but does not have a significant impact on overall ADL scores.

The use of assessment tools has been shown to improve the inter-rater reliability of capacity assessments. However, instrument-based capacity assessments of people with dementia face challenges. In dementia research, measuring capacity with instruments like the MacArthur Competence Assessment Tool for Treatment (MacCAT-T) mostly employ hypothetical treatment vignettes that can overwhelm the abstraction capabilities of people with dementia and are thus not always suitable for this target group. The primary aim of this study was to provide a standardized real informed consent paradigm that enables the dementia-specific properties of capacity to consent to treatment in people with dementia to be identified in a real informed consent process that is both externally valid and ethically justifiable.

The sample consisted of 53 people with mild to moderate dementia and a group of 133 people without cognitive impairment. Rather than using a hypothetical treatment vignette, we used a standardized version of the MacCAT-T to assess capacity to consent to treatment with cholinesterase inhibitors in people with dementia. Inter-rater reliability, item statistics, and psychometric properties were also investigated.

Intraclass correlations (ICCs) (0.951–0.990) indicated high inter-rater reliability of the standardized real informed consent paradigm. In the dementia group, performance on different items of the MacCAT-T varied. Most people with dementia were able to express a treatment choice, and were aware of the need to take a tablet. Further information on the course of the disorder and the benefits and risks of the treatment were less understood, as was comparative reasoning regarding treatment alternatives.

The standardized real informed consent paradigm enabled us to detect dementia-specific characteristics of patients’ capacity to consent to treatment with cholinesterase inhibitors. In order to determine suitable enhanced consent procedures for this treatment, we recommend the consideration of MacCAT-T results on an item level. People with dementia seem to understand only basic information. Our data indicate that one useful strategy to enhance capacity to consent is to reduce attention and memory demands as far as possible.

A consequence of pressure on hospitals to accommodate care needs of older patients is “boarding” or out-lying from their home ward. This may have greater adverse effects on older inpatients who are frail.

A retrospective matched cohort study was conducted in an outer metropolitan general hospital. Randomly selected patients hospitalized between July 2012 and June 2013 under the care of an Older Person Evaluation Review and Assessment (OPERA) team (n = 300) were age and sex matched with patients under the care of general physicians (n = 300). Frequency of boarding and number of bed moves were recorded for all patients. For patients who had three or more moves, adverse outcomes were compared between the two groups.

A higher proportion of OPERA patients (n = 143; 47.7%) were out-lied from medical wards compared with 94 (31.3%) General Medicine patients (p < 0.001). Three or more bed moves were recorded for 67 (22.3%) OPERA and 24 (8%) General Medicine patients (p < 0.001). Of those with multiple moves, OPERA patients were more likely to have pre-morbid cognitive impairment (p = 0.005), to be moderately to severely frail (p = 0.016) and to suffer acute delirium and falls during admission (p = 0.03), compared with General Medicine patients. OPERA patients were also more at risk of adverse outcomes such as increased dependence, discharge to residential care or death (p = 0.023).

Compared with age- and sex-matched General Medicine patients, OPERA patients were more likely to undergo multiple bed moves and out-lying, which may have contributed to negative outcomes for these patients.
