To estimate the impact of comorbid diabetes on caregiver stress in Alzheimer's disease (AD) patients from the Impact of Cholinergic Treatment Use (ICTUS) study.

Using the Data from the ICTUS study, diabetes mellitus (DM) was recorded at baseline and caregiver burden was assessed twice per year using the Zarit Burden Interview (ZBI) scale. The three-factorial model of ZBI (the effect on the social and personal life of caregivers, the psychological burden and the feelings of guilt) was adopted. Linear mixed models were used to examine the relation between DM and the scores of ZBI.

The present analyses were conducted on 1,264 AD subjects. A total of 156 patients (12.3%) had DM with taking antidiabetic medication and/or self-report of a history. At baseline, the caregivers of patients with or without DM had similar ZBI global scores and similar scores of three different factors of ZBI. Unadjusted and adjusted models both indicated that ZBI global score increased over a 24-month follow-up without significant effect of DM. Similarly, unadjusted model showed that DM was not determining any significant difference in the score of any factor. However, adjusted model indicated that in diabetic patients, the scores of the social and personal life of caregivers and the psychological burden increased more slowly than those in non-diabetic patients (p = 0.04 and 0.01, respectively).

DM may affect the caregivers’ daily social and personal life and psychological burden in AD patients. It is necessary for further research.

Delirium is the most frequent complication among the hospitalized elderly with hip fracture. Although, delirium is associated with longer hospital stay, higher mortality rates, worse functional outcomes, and higher institutionalization rates yet health service planners have hugely ignored its existence. This review aims to identify the effectiveness of multicomponent interventions to prevent delirium in hospitalized elderly patients with hip fracture.

This review includes experimental, non-experimental, and observational studies. Electronic searches were conducted in MEDLINE, CINAHL, PsycINFO, Cochrane Central Register of Controlled Trials, Embase, and Web of science.

After inclusion and exclusion criteria were applied, nine full text articles were included in the review. The studies reported the following effect on delirium: We pooled data regarding incidence of delirium from the three RCTs. The effect was in favor of the intervention group (odds ratio 0.64, 95% CI 0.46–0.87). All three RCTs reported that duration of delirium was shorter in the intervention group than in the usual care group (mean 2.9 vs. 3.1 days, median 3 vs. 4 days, median 5.0 vs. 10.2 days). Four other studies reported on the duration of delirium with Milisen and colleagues reported shorter duration of delirium within the intervention group. Four studies reported on severity of delirium with two research groups reporting significant results.

Early engagement of multidisciplinary staff who addresses the risk factors of delirium as soon as the patient presents to the acute care environment is the key element of a successful delirium prevention program. Once delirium had developed, the multicomponent interventions did not appear to make a difference to the duration or severity of delirium.

Affective and emotional symptoms such as depression, anxiety, euphoria, and irritability are common neuropsychiatric symptoms (NPS) in pre-dementia and cognitively normal older adults. They comprise a domain of Mild Behavioral Impairment (MBI), which describes their emergence in later life as an at-risk state for cognitive decline and dementia, and as a potential manifestation of prodromal dementia. This selective scoping review explores the epidemiology and neurobiological links between affective and emotional symptoms, and incident cognitive decline, focusing on recent literature in this expanding field of research.

Existing literature in prodromal and dementia states was reviewed, focusing on epidemiology, and neurobiology. Search terms included: “mild cognitive impairment,” “dementia,” “prodromal dementia,” “preclinical dementia,” “Alzheimer's,” “depression,” “dysphoria,” “mania,” “euphoria,” “bipolar disorder,” and “irritability.”

Affective and emotional dysregulation are common in preclinical and prodromal dementia syndromes, often being harbingers of neurodegenerative change and progressive cognitive decline. Nosological constraints in distinguishing between pre-existing psychiatric symptomatology and later life acquired NPS limit historical data utility, but emerging research emphasizes the importance of addressing time frames between symptom onset and cognitive decline, and age of symptom onset.

Affective symptoms are of prognostic utility, but interventions to prevent dementia syndromes are limited. Trials need to assess interventions targeting known dementia pathology, toward novel pathology, as well as using psychiatric medications. Research focusing explicitly on later life onset symptomatology will improve our understanding of the neurobiology of NPS and neurodegeneration, enrich the study sample, and inform observational and clinical trial design for prevention and treatment strategies.

We analyzed the impact of opioid initiation on the prevalence of antipsychotic and benzodiazepine and related drug (BZDR) use among community-dwelling persons with Alzheimer's disease (AD).

We utilized the register-based Medication use and Alzheimer's disease (MEDALZ) cohort for this study. We included all community-dwelling persons diagnosed with AD during 2010–2011 in Finland initiating opioid use (n = 3,327) and a matched cohort of persons not initiating opioids (n = 3,325). Interrupted time series analyses were conducted to compare the prevalence of antipsychotic and BZDR use in 30-day periods within six months before opioid initiation to 30-day periods six months later.

Before opioid initiation, prevalence of antipsychotic use among opioid initiators was 13.3%, 18.3% at opioid initiation, and 17.3% six months later. Prevalences of BZDR use were 27.1% six months prior, 28.9% at opioid initiation, and 26.9% six months later. After opioid initiation, antipsychotic and BZDR use declined by 0.3 percentage points (pps, 95% confidence interval 0.1–0.5) and 0.4 pps (0.2–0.7) per month, respectively, until the end of the follow-up. Compared to persons not initiating opioid use, opioid initiation immediately resulted in an increase in prevalence of 1.9 pps (0.9–2.8) for antipsychotics and of 1.6 pps (0.9–2.2) for BZDR use. However, in total there was a comparative decrease of 0.5 pps (0.3–0.8) per month for antipsychotics and of 0.4 pps (0.2–0.6) for BZDR use until the end of the follow-up.

Our results suggest that opioid initiation may reduce antipsychotic and BZDR use among persons with AD.

To study longitudinal changes in the quality of life (QoL) in persons with and without dementia, and explore the factors associated with baseline QoL and changes of QoL over the follow-up period.

Prospective longitudinal study.

Data were collected from 17 municipalities in Norway in the period from January 2009 to August 2012. A total of 412 persons were included, 254 (61.7 %) persons without dementia and 158 (38.3 %) with dementia at baseline.

Persons 70 years of age or older, receiving municipal care services. Main outcome measures include the following: self-rated and proxy-rated QoL over a period of 18 months, cognitive status, functional status, neuropsychiatric symptoms, and demographics.

Longitudinal changes in QoL were small, despite changes in clinical variables. Proxy ratings of patients QoL were lower than the patients’ own ratings. Belonging to a group with low QoL trajectory was associated with symptoms of depression, reduced physical and instrumental functioning, and more severe dementia.

Patients and proxies evaluated the patients’ QoL differently and QoL did not necessarily correspond with deterioration in clinical parameters. To prevent impaired QoL, we need to address identified factors and keep an approach open to the individual perceptions of QoL.

Prescribed Disengagement® is the description of the post-diagnostic advice given to people after a diagnosis of dementia, which explicitly or implicitly suggests that the person should be slowing down or pulling back from activities. This results in isolation, loss of hope, self-esteem and self-identity, and threatens social health. This study aims to review whether Prescribed Disengagement® can be identified in the literature on subjective experiences of people living with early dementia.

A systematic search was performed. Inclusion criteria were original empirical qualitative studies published in English that addressed the subjective experiences of living with a diagnosis of objectively defined early dementia. Thematic synthesis was undertaken.

Thirty-five papers involving 373 participants were included. Following a diagnosis, people with dementia struggled with self-identity, independence, control and status, activities, stigma, and how to view the future. Reactions in these areas ranged from active and positive to negative and passive. Many studies reported participants’ dissatisfaction with the way the diagnosis was communicated. There was insufficient information provided about dementia and limited treatments and support offered. The diagnosis process and post-diagnostic support may have contributed to disempowerment of the person with dementia, made it more difficult to accept the diagnosis, and exacerbated negative views and self-stigma around dementia.

These results do not support the idea of Prescribed Disengagement®. However disengagement may have been implied during the diagnosis process and post-diagnostic support. Research is needed on how to improve the communication of dementia diagnosis and support people to live well post-diagnosis.

Person-centered care (PCC) is regarded as good quality care for persons with dementia. This study aimed to explore and understand the association between PCC and organizational, staff and unit characteristics in nursing homes (NHs).

Staff from 175 NH units in Norway (n = 1,161) completed a survey, including measures of PCC and questions about staff characteristics and work-related psychosocial factors. In addition, data about organizational and structural factors and assessment of the physical environment in the units were obtained. The distribution of these factors in regular units (RUs) and special care units (SCUs) is described, and the differences between the two types of units are analyzed. Furthermore, multilevel linear regression analyses explored the extent to which variables were associated with PCC.

Higher levels of PCC were associated with a greater job satisfaction, three years or more of health-related education, a lower level of quantitative demands and role conflict, a higher level of perception of mastery, empowering leadership, innovative climate and perception of group work, in addition to the type of unit and the physical environment in the NH unit designed for people with dementia. SCU and staff job satisfaction explained most of the variation in PCC.

This study shows an association between PCC and organizational, staff and unit characteristics in NH. These findings indicate that providing PCC in NH care is closely linked to how the staff experiences their job situation in addition to both organizational and structural factors and the physical environment. Attention needs to be given to such factors when planning NH care.

The early and effective detection of neurocognitive disorders poses a key diagnostic challenge. We examined performance on common cognitive bedside tests according to differing delirium syndromal status and clinical (motor) subtypes in hospitalized elderly medical inpatients.

A battery of nine bedside cognitive tests was performed on elderly medical inpatients with DSM-IV delirium, subsyndromal delirium (SSD), and no delirium (ND). Patients with delirium were compared according to clinical (motor) subtypes.

A total of 198 patients (mean age 79.14 ± 8.26) were assessed with full syndromal delirium (FSD: n = 110), SSD (n = 45), and ND (n = 43). Delirium status was not associated with differences in terms of gender distribution, age, or overall medication use. Dementia burden increased with greater delirium status. Overall, the ability to meaningfully engage with the tests varied from 59% for the Vigilance B test to 85% for Spatial Span Forward test and was lowest in patients with FSD, where engagement ranged from 32% for the Vigilance B test to 77% for the Spatial Span Forwards test. The ND group was distinguished from SSD group for the Months of the year backwards, Vigilance B, global VSP, Clock Drawing test, and Interlocking Pentagons test. The SSD group was distinguished from the FSD group by Vigilance A, Spatial Span Forward, and Spatial Span Backwards. Regarding differences among motor subtypes in terms of percentage engagement and performance, the No subtype group had higher ratings across all tests. Delirious patients with no subtype had significantly lower scores on the DRS-R98 than for the other three subtype categories.

Simple bedside tests of attention, vigilance, and visuospatial ability are useful in distinguishing neurocognitive disorders, including SSD from other presentations.

Dementia caregiving is often stressful and depression in family caregivers is not uncommon. As caregiver depression can have significant effects, there is a need for preventive efforts which are consistent with the extensive literature. We sought to consolidate the wide range of evidence (using a multi-method approach) into a simple framework that can guide the prevention of caregiver depression.

Using multiple logistic regression, we derived the predictors of caregiver depression from an empirical dataset containing key information and depression scores (based on the Center-for-Epidemiological-Studies-Depression-Scale) of 394 family caregivers. We then chose an underpinning theory as the foundation of the framework, and conducted an umbrella systematic review to find possible links between the derived predictors and the theory. Last, we compared the iterated framework with known interventions for caregiver depression in recent literature to assess whether the framework could map meaningfully with the known interventions.

Significant predictors of caregiver depression included primary caregiver (odds ratio, OR = 1.53), severe dementia (OR = 1.40), and behavioral problems (OR = 3.23), lower education (OR = 1.77), and spousal caregivers (OR = 1.98). The integrated framework derived focuses on four strategic areas: physical-care demands of persons with dementia (PWD), behavioral problems of PWD, caregiving competency, and loss and grief of caregivers. This framework is supported by known interventions for caregiver depression in recent literature.

By consolidating a broad range of evidence, we iterated a framework to aid the understanding and prevention of caregiver depression in dementia. The framework offers an approach to prevention which is simple, systematic, and reflective of the extensive literature.

Evidence suggests that semantic interference may be a sensitive indicator of early dementia. We examined the utility of the Semantic Interference Test (SIT), a cognitive stress memory paradigm which taps proactive and retroactive semantic interference, for predicting progression from mild cognitive impairment (MCI) to dementia in both a clinical and a population-based sample.

Participants with MCI in the clinical (n = 184) and population-based (n = 435) samples were followed for up to four years. We employed receiver operating characteristic (ROC) methods to establish optimal thresholds for four different SIT indices. Threshold performance was compared in the two samples using logistic and Cox proportional hazard regression models.

Within four years, 42 (22.8%) MCI individuals in the clinical sample and 45 (10.3%) individuals in the population-based sample progressed to dementia. Overall classification accuracy of SIT thresholds ranged from 61.4% to 84.8%. Different subtests of the SIT had slightly different performance characteristics in the two samples. However, regression models showed that thresholds established in the clinical sample performed similarly in the population sample before and after adjusting for demographics and other baseline neuropsychological test scores.

Despite differences in demographic composition and progression rates, baseline SIT scores predicted progression from MCI to dementia similarly in both samples. Thresholds that best predicted progression were slightly below thresholds established for distinguishing between amnestic MCI and cognitively normal subjects in clinical practice. This confirms the utility of the SIT in both clinical and population-based samples and establishes thresholds most predictive of progression of individuals with MCI.

The aim of the present study was to investigate the psychometric characteristics of the Perceived Stress Scale (PSS) in a sample of dementia patients and their spousal caregivers.

We investigated the reliability and validity of the 14-item PSS in a sample of 80 couples, each including one spouse who had been diagnosed with mild to moderate dementia (mean age 75.55, SD = 5.85, 38.7% female) and one spousal caregiver (mean age 73.06, SD = 6.75, 61.3% female). We also examined the factor structure and sensitivity of the scale with regard to gender differences.

Exploratory factor analysis of the PSS revealed a two-factor solution for the scale; the first factor reflected general stress while the second factor consisted of items reflecting the perceived ability to cope with stressors. A confirmatory factor analysis verified that the data were a better fit for the two-factor model than a one-factor model. The two factors of the PSS showed good reliability for patients as well as for caregivers ranging between α = 0.73 and α = 0.82. Perceived stress was significantly positively correlated with depressive symptomatology in both caregivers and patients. Mean PSS scores did not significantly differ between male and female patients nor did they differ between male and female caregivers.

The present data indicate that the PSS provides a reliable and valid measure of perceived stress in dementia patients and their caregivers.

Sedative–hypnotic medication use has been related to severe adverse events and risks. This study investigated the prevalence of and characteristics associated with the use of sedatives and hypnotics among community-dwelling elderly persons aged 65 years and over in Taiwan.

A representative sample of community-dwelling adults was recruited. Clinical and sociodemographic data were collected for assessing physical, mental, and cognitive functioning and disorders. Sedatives and hypnotics use was determined via both self-reporting and prescription records. Logistic regression modeling was used to evaluate associations between sedative–hypnotic use and demographic and health status.

Among the 3,978 participants aged 65 years and over, the rate of sedative–hypnotic use was 19.7% (n = 785). 4.5% (n = 35) of users reported sedative–hypnotic use without a doctor's prescription. Several sociodemographic characteristics were positively associated with sedative and hypnotic use, including older age, female gender, higher education level, married status, unemployment, and current alcohol consumption. Comorbid chronic and cardiovascular diseases, mental illness, depression, pain, and sleep problems also increased the likelihood of sedative–hypnotic use.

This study is one of the largest pioneer studies to date to survey sedatives–hypnotics use among community-dwelling elderly. One in five community-dwelling older adults reported sedative–hypnotic drugs use in Taiwan, and about 5% of sedative and/or hypnotics usage was without a doctor's prescription. Findings could be helpful for drug-use safety interventions to identify target geriatric patients who are in general at higher risk of downstream harm associated with sedative–hypnotic use in geriatric patients.

Suicide rates increase with age in the population aged over 65 years. The aims of this study were to (i) report the characteristics of older people who died by suicide; and (ii) investigate whether these characteristics differ in three age bands: 65–74 years, 75–84 years, and 85+ years.

Using information from national coroner records, relevant socio-demographic and clinical factors in all suicides (age ≥ 65 years; n = 225) from July 2007 to December 2012 in New Zealand were analyzed and compared in the three age bands.

We found the older the person, the more likely they are to be widowed but the less likely to have a past psychiatric admission or recent contact with psychiatric services in the month prior to suicide. However, most of the older people (61.7% of 65–74 years, 65.6% of 75–84 years, and 77.3% of 85+ years) had contact with their general practitioner within one month of suicide. Women were less likely to use violent methods than men in all three age bands but with increasing age, men were less likely to use violent methods.

Suicide characteristics in older people differ by age. The oldest people who die by suicide are not necessarily under psychiatric services and may benefit from a primary care-based approach in which there is screening for depression and suicide risk.

The use of the pharmacopsychometric triangle to enhance patient-reported well-being as the ultimate goal of treatment has most intensively been studied in patients with a major depressive episode.

The review is structured on the pharmacopsychometric triangle in which the desired clinical effect of an antidepressive medication is balanced against the undesired side effects induced by this medication in terms of restored well-being. As a biological treatment, the antidepressive medication is compared clinically with both electroconvulsive therapy and psychological treatment.

In the process of this review, evidence from a dose–response study in patients suffering from a major depressive episode with an adequate duration and symptom severity has demonstrated that the dose–response relationship emerged when using the patient-reported well-being outcome rather than the symptomatic reduction as outcome.

The pharmacopsychometric triangle is in patients with major depressive episodes providing important information within positive psychiatry.

The unprecedented increase in the number of older adults moving into aged care facilities has created a challenge for quality person-centered care service provision. This study examined the impact of written life-stories on knowledge and attitudes of care staff about the residents when compared to usual file notes.

A randomized controlled study was carried out with 40 staff working in an aged care residential facility. Staff were randomly assigned to a control condition, in which they read file notes (n = 21) or to an experimental condition, in which they read life stories (n = 19) about residents who they knew, and completed the Knowledge of Resident Scale (KRS) before and after their assigned reading.

A main effect for time was found for eight of the ten questions on the KRS, suggesting that irrespective of whether a participant read life stories or file notes, there was a significantly positive impact on knowledge and attitudes toward residents. However, significantly greater improvement was shown for one item on the KRS in the experimental condition when compared to the control condition, indicating that historical knowledge of residents was greater when staff read life stories than when they read file notes, F (1,38) = 6.50, p = 0.02.

These results provide preliminary evidence that knowledge and attitudes of care staff can increase about the residents for whom they care following reading file notes and life stories. The increase is similar, except in the area of historical information, where it is greater for the group who read life stories.

New onset of mood and behavioral changes in middle-aged patients are frequently the first manifestations of an unrecognized neurocognitive disorder. Impairment of social cognition, the cognitive ability to process social information coming from others, such as emotions, to attribute mental states to others, and to respond appropriately to them, is often at the origin of behavioral manifestations in neurodegenerative disorders.

This paper reviews the current literature on social cognition impairment in neurocognitive disorders, particularly in prodromal stages of behavioral-variant frontotemporal dementia (bvFTD), Alzheimer's disease (AD), idiopathic Parkinson's disease (IPD), and Lewy body dementia (LBD). The concepts of social cognition will be reviewed, including its impairment and neural basis, its clinical assessment, and the different therapeutic interventions available clinically.

Socially inappropriate behaviors, such as loss of empathy, inappropriateness of affect, and disinhibition are frequently reported in prodromal bvFTD and in prodromal AD. Lack of self-control, reduced perception of social cues, such as recognition of facial emotions and sarcastic speech, and impaired Theory of Mind all contribute to the neuropsychiatric symptoms and are secondary to neurodegeneration in specific brain regions. In contrasts to bvFTD and AD, deficits in social cognition in IPD occur later in the course of the disease and are often multifactorial in origin.

Through various manifestations, social inappropriateness is frequently the first clinical sign of a neurodegenerative process, especially in AD and bvFTD, years before noticeable impairment on classical neuropsychological assessment and brain atrophy on imaging.

The objectives of the study were to examine the trajectory of spirituality among older adults, to investigate the roles of gender and religion on the developmental trajectory of spirituality, and to explore whether the linear growth of spirituality accelerated or decelerated at time points at which the participants reported high scores of social support and flexibility.

A five-year longitudinal study.

The research used data from a longitudinal study, which follows a non-institutionalized older adults cohort of residents from France. The data used in this paper were collected at three time points (T1: 2007; T2: 2009; T3: 2012).

A total of 567 participants were included in the analysis (59.44% female; Mage = 75.90, SD = 5.12).

Multilevel growth curve analysis was used measuring spirituality, satisfaction with social support, and flexibility.

The results indicated the following: (1) stability of spirituality over time, (2) older women reported higher levels of spirituality than older men, and those who had a religion reported higher scores of spirituality than their counterparts who had no religion (these effects were strong and clinically meaningful), (3) older adults who reported higher levels of social support and flexibility also reported higher levels of spirituality, and (4) the slope of spirituality seemed to accelerate at time points at which participants also had higher levels of social support and flexibility (these effects were rather small but of theoretical interest).

The results of the present study help to improve the understanding of the potential benefit of encouraging the spiritual aspects of life.

The care of community-dwelling people with dementia often occurs in the context of pre-existing family relationships. The presence of dementia can result in changes to the quality of those relationships. The purpose of this systematic review is to identify factors that enhance or challenge the quality of spousal or offspring relationships in the context of dementia.

Both qualitative and quantitative studies were included in a systematic review of the literature. Thematic analysis of results was conducted that examined factors related to the relationship quality of community dwelling people with dementia and their spousal or offspring carer. Meta-analysis was not possible due to the heterogeneity of the included studies.

Four themes were extracted from seven qualitative studies: connection to the carer role; identity of the people with dementia; current efforts to maintain relationship connection; and the dyads response to dementia. Each of these four themes incorporated positive and negative facets that impacted on relationship quality. An analysis of nine quantitative and one mixed methods studies identified four domains: influence of dementia characteristics; connection within the dyad; relationship response to stress and carer burden; and carer demographic factors.

The findings of this review highlight relationship factors that are important for supporting relationship quality for the people with dementia and the carer individually, as well as for the dyad together. These findings extend an existing framework of relationship quality in dementia. Implications for interventions to enhance relationship quality in the dementia context are discussed.
