In the limited research into suicides in older adults, they have been treated as a homogenous group without distinguishing between different age groups. This study aimed to compare differences in sociodemographic variables, recent life events, and mental and physical illnesses between three age groups within older adults who died by suicide: young-old (65–74 years), middle-old (75–84 years), and oldest old (85 years and over) in Queensland, Australia, during the years 2000–2012 (N = 978).
Methods:
The Queensland Suicide Register was utilized for the analysis. Annual suicide rates were calculated. Odds ratios with 95% confidence intervals and χ2 tests for trend were calculated to examine differences between the three groups.
Results:
Suicide rates were increasing with age for males, but not for females. Hanging and firearms were the predominant methods of suicides. However, suffocation by plastic bag and drowning as suicide methods increased with age, in contrast firearms and explosives decreased with age. Overall, psychiatric problems, suicidal behavior, legal and financial stressors, and relationship problems decreased significantly with age, meanwhile physical conditions and bereavement increased with age.
Conclusion:
Suicide across older adulthood is not a homogenous phenomenon. Our findings showed significant differences in the prevalence of potential risk factors within the three different age groups considered. To prevent suicide in older adults would require targeting specific factors for each subgroup while using holistic and comprehensive approaches.
Individuals with dementia may appear before the court in different roles: as victims, as witnesses, and as those standing up for their rights. While there is growing interest in the rights of older persons with dementia, relatively little empirical data exists regarding their actual interactions in courts. Therefore, the goal of this study was to empirically map this legal terrain.
Methods:
This study used a descriptive quantitative method. A computerized search of a national legal database limited to the period 2004–2014 and a screening process for the results were used to establish a sample of 280 court rulings that directly addressed dementia. All cases were analyzed and categorized into the following four criteria groups: characteristics of the person with dementia; characteristics of the legal procedure; the legal substance of the case; and the legal outcome.
Results:
The majority of cases involved a single, very-elderly (i.e. over 80 years) woman, living in the community, with unspecified dementia. The majority of cases were heard and decided in lower level courts, addressing a broad range of primarily non-criminal legal issues. Finally, in the majority of non-criminal cases, the person with dementia was found to be legally capable, whereas in the majority of criminal cases, the person with dementia was found incapable.
Conclusions:
The legal needs and rights of persons with dementia are much broader than issues of legal capacity or social protection. Deeper knowledge and more research is needed in order to fully understand the contexts in which dementia is constructed under the law.
The Dementia Care Mapping (DCM) method is an internationally recognized complex intervention in dementia research and care for implementing person-centered care. The Leben-QD II trial aimed to evaluate the effectiveness of DCM with regard to caregivers.
Methods:
The nine participating nursing home units were allocated to three groups: (1) DCM method experienced ≥ 1 year, (2) DCM newly introduced during this trial, and (3) regular rating of residents’ quality of life (control group). Linear mixed models were fit to cluster-aggregated data after 0, 6, and 18 months, adjusting for repeated measurements and confounders. The primary outcome was the Approaches to Dementia Questionnaire (ADQ) score; the secondary outcomes were the Copenhagen Psychosocial Questionnaire (COPSOQ) and the Copenhagen Burnout Inventory (CBI).
Results:
The analysis included 201 caregivers with 290 completed questionnaires (all three data collection time points). The ADQ showed a significant time and time*intervention effect. At baseline, the estimated least-square means for the ADQ were 71.98 (group A), 72.46 (group B), and 71.15 (group C). The non-linear follow-up of group A indicated an estimated-least square means of 69.71 (T1) and 68.97 (T2); for group B, 72.80 (T1) and 72.29 (T2); and for group C, 66.43 (T1) and 70.62 (T2).
Conclusions:
The DCM method showed a tendency toward negatively affecting the primary and secondary outcomes; this finding could be explained by the substantial deviation in adherence to the intervention protocol.
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.
Methods:
In this cross-sectional study, 122 caregivers for patients with AD completed questionnaires assessing informal social support, depressive symptoms, and general life satisfaction.
Results:
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).
Conclusion:
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.
Family caregivers of people with dementia have significant unmet needs in regard to their caregiving role. Despite this, they are reluctant to utilize services to reduce their burden. The aim of this study was to examine the barriers and facilitators of service use among family caregivers of people with dementia.
Method:
Semi-structured interviews were conducted with 24 family caregivers of community-dwelling people with dementia. Of these, 12 were partner caregivers (4 men, 8 women) and 12 were offspring caregivers (2 men, 10 women). The interviews were transcribed and analyzed using thematic analysis.
Results:
Six main barriers and three facilitators were identified. These barriers and facilitators were relevant across many types of services and supports. The barriers were: the inability to find information about relevant services or support, the poor quality or mistrust of the services, the inflexibility of services, caregivers’ beliefs about their obligations to the caregiving role and resistance by the care recipient. Key facilitators were: having good communication with the care recipient, having an “expert” point of contact, and having beliefs about the caregiving role that enabled the use of services.
Conclusion:
Given the significant changes in the aged care service-system, it is important to discuss the barriers faced by family caregivers of people with dementia. This will inform the development of targeted strategies to address the lack of service use among these family caregivers.
The relation between body weight status and depressive symptoms in the elderly differs according to age and country of origin. The goal of this study was to analyze the cross-sectional and longitudinal relationship between body mass index (BMI), waist circumference (WC) and depressive symptoms in the elderly.
Methods:
A population-based cohort study of 1,702 elderly individuals (70.6+8.0 years) in Southern Brazil evaluated in 2009/10 and 2013/14 was accessed. The body weight status was assessed using measured data of BMI and WC. The Geriatric Depression Scale (GDS-15) was used to determine depressive symptoms. Logistic regression analysis adjusted for sociodemographic and behavioral variables was performed.
Results:
The prevalence of depressive symptoms in 2009/10 was 23.3% (95% CI 20.3–26.6) and the cumulative incidence in the 4-years period was 10.9% (95% CI 8.7–13.6). Elderly people with obesity class II–III and WC in the highest quartile had higher prevalence odds ratio of being depressed than individuals with normal weight or WC in the lower quartile (OR 2.34; 95% CI 1.42–3.87 and OR 1.73; 95% CI 1.13–2.65, respectively). Meanwhile, intermediary values of BMI and WC were associated with a lower prevalence. When evaluating the incidence of depressive symptoms, overweight individuals and those in the second quartile of WC had a lower risk (58% and 57%, respectively), but severely obese individuals had the same risk compared to those with normal BMI/WC.
Conclusions:
Severely obese individuals presented a similar incidence of depressive symptoms compared to those with normal BMI/WC, but higher prevalence. Intermediary values of body weight status decrease the risk of depressive symptoms.
Late-life depression is often associated with cognitive impairments and disability, which may persist even after adequate antidepressant drug treatment. Physical exercise is increasingly recognized as an effective antidepressant agent, and may exert positive effects on these features too. However, few studies examined this issue, especially by comparing different types of exercises.
Methods:
We performed secondary analyses on data from the Safety and Efficacy of Exercise for Depression in Seniors study, a trial comparing the antidepressant effectiveness of sertraline (S), sertraline plus thrice-weekly non-progressive exercise (S+NPE), and sertraline plus thrice-weekly progressive aerobic exercise (S+PAE). Exercise was conducted in small groups and monitored by heart rate meters. Patients with late-life depression without severe cognitive impairment were recruited from primary care and assessed at baseline and 24 weeks, using the Montreal Cognitive Assessment (MOCA, total and subdomain scores) and Brief Disability Questionnaire. Analyses were based on Generalized Linear Models.
Results:
In total, 121 patients (mean age 75, 71% females) were randomized to the study interventions. Compared with the S group, patients in the S+PAE group displayed greater improvements of MOCA total scores (p=0.006, effect size=0.37), visuospatial/executive functions (p=0.001, effect size=0.13), and disability (p=0.02, effect size=−0.31). Participants in the S+NPE group did not display significant differences with the control group.
Conclusions:
Adding aerobic, progressive exercise to antidepressant drug treatment may offer significant advantages over standard treatment for cognitive abilities and disability. These findings suggest that even among older patients exercise may constitute a valid therapeutic measure to improve patients’ outcomes.
Robots have the potential to both enable older adults with dementia to perform daily activities with greater independence, and provide support to caregivers. This study explored perspectives of older adults with Alzheimer's disease (AD) and their caregivers on robots that provide stepwise prompting to complete activities in the home.
Methods:
Ten dyads participated: Older adults with mild-to-moderate AD and difficulty completing activity steps, and their family caregivers. Older adults were prompted by a tele-operated robot to wash their hands in the bathroom and make a cup of tea in the kitchen. Caregivers observed interactions. Semi-structured interviews were conducted individually. Transcribed interviews were thematically analyzed.
Results:
Three themes summarized responses to robot interactions: contemplating a future with assistive robots, considering opportunities with assistive robots, and reflecting on implications for social relationships. Older adults expressed opportunities for robots to help in daily activities, were open to the idea of robotic assistance, but did not want a robot. Caregivers identified numerous opportunities and were more open to robots. Several wanted a robot, if available. Positive consequences of robots in caregiving scenarios could include decreased frustration, stress, and relationship strain, and increased social interaction via the robot. A negative consequence could be decreased interaction with caregivers.
Conclusions:
Few studies have investigated in-depth perspectives of older adults with dementia and their caregivers following direct interaction with an assistive prompting robot. To fulfill the potential of robots, continued dialogue between users and developers, and consideration of robot design and caregiving relationship factors are necessary.
Due to previously reported mixed findings, there is a need for further empirical research on the factorial structure of the commonly used Geriatric Anxiety Inventory (GAI). Therefore, the psychometric properties of the GAI and its short form version (GAI-SF) were evaluated in a psychogeriatric mixed in-and-out patient sample (n = 543).
Methods:
Unidimensionality was tested using a bifactor analysis. Rasch modeling was used to assess scale properties. Sex, cognitive functioning and depressive symptoms were tested for differential item functioning (DIF).
Results:
The bifactor analysis identified an essential unidimensional (general) factor structure but also specific local factors. The general factor comprises all the 20 items as one factor, and the results showed that the variance in the general and specific factors (subscale) scores is best explained by the single general factor. These findings were demonstrated for both versions of the GAI. Furthermore, the Rasch models identified extensive item overlap, indicating redundant items in the full version of the GAI. The GAI-SF also seems to extract much of the same information as the full form. Test scores and items have the same meaning for older adults across different demographic status.
Conclusion:
The findings support the use of a total sum score for both GAI and GAI-SF. Notably, when using the GAI-SF, no information is lost, in comparison with the full scale, thus, supporting the option of choosing the short form (version) when considered most appropriate in demanding clinical contexts.
Online tools can be used by people with dementia and their caregivers to self-identify and track troubling symptoms, such as verbal repetition. We aimed to explore verbal repetition behaviors in people with dementia.
Methods:
Participants were recruited via an online resource for people with dementia and their caregivers. Respondents were instructed to complete information about symptoms that are most important to them for tracking over time. In this cross-sectional study, we analyzed data pertaining to individuals with dementia who had at least three symptoms selected for tracking.
Results:
Of the 3,573 participants who began a user profile, 1,707 fulfilled criteria for analysis. Verbal repetition was identified as a treatment target in 807 respondents (47.3%). Verbal repetition was more frequent in individuals with mild dementia compared to those with moderate and severe dementia (57.2% vs. 36.0% and 39.9%, p < 0.01) and in those with Alzheimer's disease versus other dementias (65.2% vs. 29.7%, p < 0.001). Repetitive questioning was the most frequent type of verbal repetition (90.5% of individuals with verbal repetition). Verbal repetition was most strongly associated with difficulties operating gadgets/appliances (OR 3.65, 95%CI: 2.82–4.72), lack of interest and/or initiative (3.52: 2.84–4.36), misplacing or losing objects (3.25: 2.64–4.01), and lack of attention and/or concentration (2.62: 2.12–3.26).
Conclusions:
Verbal repetition is a common symptom in people at all stages of dementia but is most commonly targeted for monitoring and treatment effects in its mild stage. Much research is required to further elucidate the underlying mechanisms and the effect of different treatment strategies.
Globally, suicide rates increase with age, being highest in older adults. This study analyzed differences in suicides in older adults (65 years and over) compared to middle-aged adults (35–64 years) in Queensland, Australia, during the years 2000–2012.
Methods:
The Queensland Suicide Register was utilized for the analysis. Annual suicide rates were calculated by gender and age group, and odds ratios with 95% confidence intervals were examined.
Results:
In Queensland, the average annual rate of suicides for older adults was 15.27 per 100,000 persons compared to 18.77 in middle-aged adults in 2000–2012. There were no significant changes in time trends for older adults in 2002–2012. Suicide methods differed between gender and age groups. Older adults who died by suicide were more likely to be male, widowed, living alone or in a nursing home, and out of the work force. The prevalence of untreated psychiatric conditions, diagnosed psychiatric disorders, and consultations with a mental health professional three months prior to death was lower in older adults than middle-aged adults. Somatic illness, bereavement, and attention to suicide in the media were more common among older adults than middle-age adults. Older females were particularly more likely to pay attention to suicide in the media.
Conclusion:
Our findings show older adults who died by suicide were more likely to experience somatic illnesses, bereavement, and pay attention to suicide in the media compared to middle aged. Preventing suicide in older adults would therefore require holistic and comprehensive approaches.
There is paucity in the level of knowledge on the actual insurer expenses associated with patients suffering with dementia in the developing world. Less is known about direct costs by severity and how costs vary because of the presence of other comorbidities.
Methods:
Using claims data from an insurer for three years, we identified patients with AD with an algorithm that takes advantage of information on age, primary diagnosis, and services and drugs provided.
Results:
Distribution by dementia stage was as follows: mild 21%, moderate 53%, severe 17%, and undetermined 9%. Expenses paid for all causes by the insurer were at least double than estimated in the literature and were increasing annually at rates higher than 30%. Also, 92% of patients have at least another chronic condition.
Conclusions:
Worldwide costs of dementia estimates maybe underestimating the actual costs to health systems in the developing world.
It is unclear whether health service use influences the association between psychiatric and physical co-morbidity and suicide risk in older adults.
Methods:
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.
Results:
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.
Conclusions:
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.
Despite the high risk of falling for people with severe mental illness, there is limited falls research in mental health settings. Therefore, the objective of this observational cohort study was to conduct a focused post-fall review of fall episodes within aged acute inpatient mental health units at one of Australia's largest publicly funded mental health organizations.
Methods:
A post-fall reporting tool was developed to collect intrinsic and extrinsic fall risk factors among three aged acute mental health inpatient units over an 18-month period. Descriptive and inferential analyses were conducted to describe fall risk factors and predictors of fall risk.
Results:
There were a total of 115 falls, of which the tool was used for 93 (80.9%) episodes. Falls occurred most often in consumer's bedroom/bathroom and were unwitnessed. Intrinsic risk factors were most often attributed to postural drop and losing balance during walking. However, that was in contrast to consumer's who self-reported feeling dizzy as the reason of the fall.
Conclusions:
Based on the cohort, future falls could be reduced by targeting those aged above 82 years, or with a diagnosis of dementia. Recurrent falls during admission could be reduced by targeting those with psychotic illness and males with a diagnosis of dementia. A clearer dialogue among consumers and clinical staff reporting about fall episodes may support future remedial interventions and inform programs to reduce fall risk and assist the challenge of describing unwitnessed falls in aged acute inpatient mental health settings.
Interventions to support and skill paid home carers and managers could potentially improve health and well-being of older home care clients. This is the first systematic review of interventions to improve how home carers and home care agencies deliver care to older people, with regard to clients’ health and well-being and paid carers’ well-being, job satisfaction, and retention.
Methods:
We reviewed 10/731 papers found in the electronic search (to January 2016) fitting predetermined criteria, assessed quality using a checklist, and synthesized data using quantitative and qualitative techniques.
Results:
Ten papers described eight interventions. The six quantitative evaluations used diverse outcomes that precluded meta-analysis. In the only quantitative study (a cluster Randomized Controlled Trial), rated higher quality, setting meaningful goals, carer training, and supervision improved client health-related quality of life. The interventions that improved client outcomes comprised training with additional implementation, such as regular supervision and promoted care focused around clients’ needs and goals. In our qualitative synthesis of four studies, intervention elements carers valued were greater flexibility to work to a needs-based rather than a task-based model, learning more about clients, and improved communication with management and other workers.
Conclusions:
There is a dearth of evidence regarding effective strategies to improve how home care is delivered to older clients, particularly those with dementia. More research in this sector including feasibility testing of the first home care intervention trials to include health and life quality outcomes for clients with more severe dementia is now needed.
It remains unclear so far whether the role of cognitive reserve may differ between physically frail compared to less frail individuals. Therefore, the present study set out to investigate the relation of key markers of cognitive reserve to cognitive status in old age and its interplay with physical frailty in a large sample of older adults.
Methods:
We assessed Mini-Mental State Examination (MMSE) in 701 older adults. We measured grip strength as indicator of physical frailty and interviewed individuals on their education, past occupation, and cognitive leisure activity.
Results:
Greater grip strength, longer education, higher cognitive level of job, and greater engaging in cognitive leisure activity were significantly related to higher MMSE scores. Moderation analyses showed that the relations of education, cognitive level of job, and cognitive leisure activity to MMSE scores were significantly larger in individuals with lower, compared to those with greater grip strength.
Conclusions:
Cognitive status in old age may more strongly depend on cognitive reserve accumulated during the life course in physically frail (compared to less frail) older adults. These findings may be explained by cross-domain compensation effects in vulnerable individuals.
This study was conducted to estimate prevalence rates and risk factors for late-life depression in a large nationwide representative sample from Taiwan.
Methods:
A total of 5,664, randomly sampled individuals aged ≥55 years were enrolled. Clinically, relevant depressive symptoms were classified using the Center for Epidemiological Studies Depression Scale (CES-D score ≥16), and major depression was confirmed using the Primary Care Evaluation of Mental Disorders. Individuals with clinically relevant depressive symptoms, who did not meet the strict diagnostic criteria for major depression, were considered to have minor depression. Multinomial logistic regression analyses were conducted to identify risk factors for major and minor depression, including socio-demographic characteristics, medical conditions, lifestyle behaviors, social support network, and life events.
Results:
The prevalence rates of minor and major depression were 3.7% and 1.5%, respectively. Major depression was associated with personal vulnerability factors, such as poor social support, cognitive impairment, comorbid pain conditions, and sleep disturbance. However, minor depression was more likely to be related to adverse life events, including increased burden on families, changes in health status, or relationship problem. Approximately, 20.0% of individuals with major depression received antidepressant treatment.
Conclusions:
Late-life depression was less prevalent among community-dwelling older adults in Taiwan than among populations in other countries. Our findings may aid the early detection and treatment of late-life depression and provide a basis for future investigations.
There are concerns about the quality of care that people with dementia receive in the general hospital. Staff report a lack of confidence and inadequate training in dementia care.
Methods:
A train-the-trainer model was implemented across eight acute hospital trusts in London via a large academic health and science network. Impact was evaluated using mixed methods. Data were collected at (a) individual level: “Sense of Competence in Dementia Care” (SCID), (b) ward level: Person Interaction and Environment (PIE) observations, (c) organization level: use of specific tools, i.e. “This Is Me,” (d) systems level: numbers and types of staff trained per trust. Results were analyzed with descriptive statistics and paired t-test with thematic framework analysis for PIE observations.
Results:
The number of staff trained per trust ranged from 67 to 650 (total 2,020). A total of 1,688 (85%) baseline questionnaires and 456 (27%) three month follow-up questionnaires were completed. Mean SCID score was 43.2 at baseline and 50.7 at follow-up (paired t-test, p < 0.001). All sub-scales showed a small increase in competence, the largest being for “building relationships.” Organizational level data suggested increased use of carer's passport, “This Is Me” documentation, dementia information leaflets, delirium screening scales, and pathways. PIE observations demonstrated improved staff–patient interactions but little change in hospital environments.
Conclusions:
There was a significant improvement in staffs’ sense of competence in dementia care and the quality of interactions with patients. More hospitals adopted person-centered tools and pathways. Work is required to investigate if these changes improve hospital outcomes for people with dementia.
The assessment of everyday functioning in dementia is currently very global and in most cases fails to provide an in-depth overview of specific areas of deficits. Every activity comprises different sub-tasks which may be impaired to different degrees. Performance of some sub-tasks might be maintained and could thus be the foundation for remaining independent for longer. Thus, the objective of this study was to explore the benefits of breaking down everyday activities into sub-tasks.
Methods:
A total of 183 family carers of people with mild dementia completed the revised Interview for Deteriorations in Daily Living Activities in Dementia 2 (R-IDDD2) rating their relative's everyday functioning. Each of the 20 activities comprised three sub-tasks. Data were analyzed using ANOVA with Bonferroni corrections, and sub-tasks were clustered in relation to different forms of cognition.
Results:
The majority of activities showed at least one major area of impairment. Sub-tasks could be clustered based on different types of cognition. Several sub-tasks had a focus on memory (forgetting it is time to do the cleaning; forgetting previously known telephone numbers), whereby short-term, long-term, and prospective memory could be distinguished further. Other sub-tasks were clustered into attention (getting more distracted when driving) and executive function (sorting out bills).
Conclusions:
The R-IDDD2 and its analysis of sub-task performance offers a novel platform to examine impairments comprehensively. This can help both in aiding timelier diagnosis by recognizing subtle deficits, but also in care management planning, whereby family and paid carers should only care for those sub-tasks that are most impaired and thus encourage remaining independent for longer.
Subjective cognitive decline (SCD) designates a self-reported cognitive decline despite preserved cognitive abilities. This study aims to explore, in older adults with SCD, the association between intensity of self-reported cognitive complaint and psychological factors including Young's early maladaptive schemas (EMSs) (i.e. enduring cognitive structures giving rise to beliefs about oneself and the world), as well as depression and anxiety.
Methods:
Seventy-six subjects (69.22 years ± 6.1) with intact cognitive functioning were recruited through an advertisement offering free participation in an intervention on SCD. After undergoing a neuropsychological examination (including global cognition (MMSE) and episodic memory (FCSRT)) and a semi-structured interview to assess depressive symptoms (MADRS), they completed a set of online self-reported questionnaires on SCD (McNair questionnaire), Young's EMSs (YSQ-short form), depression (HADS-D), and anxiety (HADS-A and trait-STAI-Y).
Results:
The McNair score did not correlate with the neuropsychological scores. Instead, it was highly (r > 0.400; p < 0.005) correlated with trait anxiety and three EMSs belonging to the “Impaired autonomy and performance” domain: Dependence/incompetence, Failure to achieve and Vulnerability to harm or illness. Our final regression model comprising depression, anxiety, and these three EMSs as predictors (while controlling for age, gender, and objective cognition) accounted for 38.5% of the observed variance in SCD intensity.
Conclusions:
The level of cognitive complaint is significantly associated with Young's EMSs in the category of “Impaired autonomy and performance”. We assume that SCD may primarily be driven by profound long-term inner beliefs about oneself that do not specifically refer to self-perceived memory abilities.
