Although non-drug interventions are widely used in patients with Alzheimer's disease, few large scale randomized trials involving a long-term intervention and several cognitive-oriented approaches have been carried out. ETNA3 trial compares the effect of cognitive training, reminiscence therapy, and an individualized cognitive rehabilitation program in Alzheimer's disease to usual care.

This is a multicenter (40 French clinical sites) randomized, parallel-group trial, with a two-year follow-up comparing groups receiving standardized programs of cognitive training (group sessions), reminiscence therapy (group sessions), individualized cognitive rehabilitation program (individual sessions), and usual care (reference group). Six hundred fifty-three outpatients with Alzheimer's disease were recruited. The primary efficacy outcome was the rate of survival without moderately severe to severe dementia at two years. Secondary outcomes were cognitive impairment, functional disability, behavioral disturbance, apathy, quality of life, depression, caregiver's burden, and resource utilization.

No impact on the primary efficacy measure was evidenced. For the two group interventions (i.e. cognitive training and reminiscence), none of the secondary outcomes differed from usual care. The larger effect was seen with individualized cognitive rehabilitation in which significantly lower functional disability and a six-month delay in institutionalization at two years were evidenced.

These findings challenge current management practices of Alzheimer's patients. While cognitive-oriented group therapies have gained popularity, this trial does not show improvement for the patients. The individualized cognitive rehabilitation intervention provided clinically significant results. Individual interventions should be considered to delay institutionalization in Alzheimer's disease.

The ongoing increase in life expectancy resulting in people living longer after the death of a lifelong spouse along with the stresses of widowhood is likely to increase the phenomenon of repartnering in old age. The aim of this article is to learn about the attributed meanings of late-life repartnering among older repartnered widows and widowers dealing with widowhood.

The experiences of 27 couples (54 participants), in which both partners were widowed, were chosen from two larger studies on late-life repartnering: one took a dyadic perspective (interviewing both partners), and the other took an intergenerational approach (interviewing both partners and offspring). Criterion sampling in both studies used the criteria of widowers who repartnered above age 65 and widows above age 60, remarried or not, living separately, or under the same roof, and who had children and grandchildren from a lifelong marriage that had ended with the death of their spouse. All semi-structured interviews were recorded, transcribed verbatim, and analyzed based on grounded theory principles and dyadic analysis adapted to families.

Present a grounded model indicating gender differences in dealing with the death of a lifelong spouse. Men tended to experience vulnerability whereas women tended to experience resilience.

These findings make an innovative contribution by showing the reversal of gender inequality in old age, and gender differences between widows’ and widowers’ coping with widowhood, even though both repartnered. They are discussed in light of (critical) feminist gerontology including contribution to theory development and implications for practice.

The relevance of mental health for everyday life functioning and well-being is crucial. In this context, higher educational attainment, higher cognitive level of one's occupation, and more engaging in stimulating leisure activities have been found to be associated with better cognitive functioning in old age. Yet, the detailed pattern of the potential interplay of such a cognitively engaged lifestyle with personality dimensions, such as openness to experience, in their relations to cognitive functioning remains unclear.

Two thousand eight hundred and twelve older adults served as sample for the present study. Psychometric tests on verbal abilities and processing speed were administered. In addition, individuals were retrospectively interviewed on their educational attainment, occupation, and regarding 18 leisure activities that had been carried out in mid-life. Moreover, openness to experience was assessed.

We found that the effect of openness to experience on cognitive functioning was mediated by educational attainment, cognitive level of job, and engaging in different leisure activities. Data were not better described by alternative moderation models testing for interactive (i.e. dependent) effects of openness to experience and cognitively stimulating engagement.

To explain interindividual differences in cognitive functioning in old age, present data are in line with a mechanism in which individuals with high openness to experience may have been more engaged in stimulating activities in early and mid-life. Possibly by increasing their cognitive reserve throughout adulthood, this may finally enhance their cognitive performance level later in old age.

Falls are highly frequent in older adults and are associated with increased morbidity and mortality. The present study was designed to assess the role of satisfaction with one's aging process as a predictor of the risk for falling over a four-year period and to identify potential mediators of this relationship.

The Health and Retirement Study (HRS) is a US nationally representative sample of individuals over the age of 50 years and their spouse of any age. The present study was based on the 2008–2012 waves of the HRS. Analyses were restricted to 4,121 respondents over the age of 50 years, who had fall data in 2008 and 2012 and were eligible to complete the satisfaction with aging measure as part of the 2008 psychosocial questionnaire.

Overall, 38.1% of the sample reported having fallen at least once between 2006 and 2008 and 40.7% reported having fallen at least once between 2010 and 2012. Higher levels of satisfaction with aging in 2008 were found to be protective against falls assessed in 2012 (OR[95%CI] = 0.88[0.79–0.98]) even after adjustment for age, gender, education, ethnicity, medical status, functional status, cognitive functioning, walking speed, balance, vision, depressive symptoms, physical activities, and past falls. Bootstrap procedures have shown that the effect of satisfaction with aging on falls is partially accounted for through its effect on functional decline.

The findings point to the important role of satisfaction with aging as a potential protective mechanism against falls. The results call for the development of psychosocial interventions to reduce falls in older adults.

Although the incidence of cancer increases with age, elderly patients are often excluded from clinical trials. In addition, elderly patients are frequently undertreated in comparison to younger patients. One explanation for these observations is age stigma (i.e. ageism). In this context, this study has two objectives: (1) to replicate the results of previous studies that reported differential support of medical treatment depending on the patient's age in a different healthcare provider population (nurses rather than physicians); and (2) to determine whether support for expensive immunotherapy, adjuvant chemotherapy, or breast reconstruction is linked to ageism among nurses.

The participants were 76 nurses who specialized in oncology. They received four clinical vignettes: one vignette about an immunotherapy with a high societal cost (age of patient: 40 vs. 70 years), and three vignettes about adjuvant chemotherapy and breast reconstruction (age of patient: 35, 55, or 75 years – age was the only difference). A questionnaire and a fluency task were used to assess the participants’ vision of aging.

Our analyses show that support for immunotherapy, breast reconstruction, and chemotherapy is lower for older patients than for younger patients. Moreover, nurses’ vision of aging influences support for breast reconstruction: nurses with a negative view of age discriminated more between a 75-year-old patient and a 35-year-old patient (less encouragement for the older patient).

These results highlight the need for nurses and other healthcare providers to receive specific training about ageism and its consequences.

Vitamin D deficiency is common in older persons. The objectives of this study were: To examine the cross-sectional and longitudinal association between serum 25-hydroxyvitamin D (25(OH)D) and cognitive functioning in older persons; and to explore the optimal cut-off for serum 25(OH)D.

Data of the Longitudinal Aging Study Amsterdam (LASA) were used. Serum 25(OH)D was determined using a competitive protein binding assay in 1995/6 (n = 1,320). Cognitive functioning was assessed in 1995/6 and 1998/9 using the Mini-Mental State Examination (MMSE, general cognitive functioning), Raven's Colored Progressive Matrices (RCPM, ability of nonverbal and abstract reasoning), the Coding Task (CT, information processing speed), and the 15 Words Test (15WT, immediate memory and delayed recall). The data were analyzed using linear regression analyses and restricted cubic spline functions. The MMSE was normalized using ln(31-MMSE).

Mean serum 25(OH)D was 53.7 nmol/L. After adjustment for confounding, patients with serum 25(OH)D levels below 30 nmol/L had significantly lower general cognitive functioning (beta of ln(31-MMSE) = 0.122; p = 0.046) and slower information processing speed (beta = −2.177, p = 0.001) as compared with patients having serum 25(OH)D levels ≥ 75 nmol/L in the cross-sectional analyses. For both outcomes, the optimal cut-off was about 60 nmol/L. No other significant associations were observed.

A lower serum 25(OH)D was significantly associated with lower general cognitive functioning and slower information processing speed, but not with a faster rate of cognitive decline.

It is unclear how brain reserve interacts with gender and apolipoprotein E4 (APOE4) genotype, and how this influences the progression of Alzheimer's disease (AD). The association between intracranial volume (ICV) and progression to AD in subjects with mild cognitive impairment (MCI), and differences according to gender and APOE4 genotype, was investigated.

Data from subjects initially diagnosed with MCI and at least two visits were downloaded from the ADNI database. Those who progressed to AD were defined as converters. The longitudinal influence of ICV was determined by survival analysis. The time of conversion from MCI to AD was set as a fiducial point, as all converters would be at a similar disease stage then, and longitudinal trajectories of brain atrophy and cognitive decline around that point were compared using linear mixed models.

Large ICV increased the risk of conversion to AD in males (HR: 4.24, 95% confidence interval (CI): 1.17–15.40) and APOE4 non-carriers (HR: 10.00, 95% CI: 1.34–74.53), but not in females or APOE4 carriers. Cognitive decline and brain atrophy progressed at a faster rate in males with large ICV than in those with small ICV during the two years before and after the time of conversion.

Large ICV increased the risk of conversion to AD in males and APOE4 non-carriers with MCI. This may be due to its influence on disease trajectory, which shortens the duration of the MCI stage. A longitudinal model of progression trajectory is proposed.

Data on the relationship between behavioral disturbances in Alzheimer's disease (AD) and global clinical deterioration is still controversial. The purpose of this study was to explore potential correlations of neuropsychiatric syndromes with global clinical deterioration in patients with AD, with particular consideration on severity levels of dementia.

AD patients (n = 156) aged 76.7 years from Brazilian clinical centers were assessed to diagnose the five neuropsychiatric syndromes measured by the Neuropsychiatric Inventory-Clinician rating scale (NPI-C): psychosis, agitation, affective, apathy, and sleep. These syndromes were then analyzed for their correlation with the Global Deterioration Scale (GDS). To analyze the association of neuropsychiatric syndromes with the GDS, considering the total sample and patients grouped by dementia severity levels, we applied the coefficient of multiple correlation (Ryy), adjusted multiple linear regression, and the coefficient of determination (R2yx). We tested the significance of correlation coefficients using the Student t-test for simple correlations (a single independent variable) and analysis of variance (ANOVA) for multiple correlations. ANOVA was also used to compare means of demographic and some clinical variables at different levels of dementia.

For the total sample, apathy and agitation syndromes were most strongly correlated (0.74; 0.72, respectively) with clinical deterioration according to the GDS, followed by psychosis (0.59), affective (0.45), and sleep syndromes (0.34). Agitation significantly correlated with mild and moderate dementia (CDR 1: 0.45; and CDR 2: 0.69, respectively). At CDR 2, agitation and affective syndromes were most strongly correlated (0.69; 0.59, respectively) with clinical deterioration while at CDR 3, the apathy syndrome was most strongly correlated with clinical deterioration (0.52).

Agitation, apathy, and affective disorders were the syndromes most strongly correlated with global deterioration in AD patients, becoming more evident at severe stages of dementia.

Self-management equips people to manage the symptoms and lifestyle changes that occur in long-term health conditions; however, there is limited evidence about its effectiveness for people with early-stage dementia. This pilot randomized controlled trial (RCT) explored the feasibility of a self-management intervention for people with early-stage dementia.

The participants were people with early-stage dementia (n = 24) and for each participant a caregiver also took part. Participants were randomly allocated to either an eight-week self-management group intervention or treatment as usual (TAU). Assessments were conducted at baseline, three months and six months post-randomization by a researcher blind to group allocation. The primary outcome measure was self-efficacy score at three months.

Thirteen people with dementia were randomized to the intervention and 11 to TAU. Two groups were run, the first consisting of six people with dementia and the second of seven people with dementia. There was a small positive effect on self-efficacy with the intervention group showing gains in self-efficacy compared to the TAU group at three months (d = 0.35), and this was maintained at six months (d = 0.23). In terms of intervention acceptability, attrition was minimal, adherence was good, and satisfaction ratings were high. Feedback from participants was analyzed with content analysis. The findings suggest the positive aspects of the intervention were that it fostered independence and reciprocity, promoted social support, offered information, and provided clinician support.

This study has provided preliminary evidence that self-management may be beneficial for people with early-stage dementia.

The aim was to develop an evidence-based model that focuses specifically on factors that enable the provision of personalized care to facilitate and promote the implementation of community-based personalized dementia care interventions. The model is based on our previous research and additional literature.

The theoretical model of adaptive implementation was used as a framework to structure our model. Facilitators and barriers considered relevant for personalized care were extracted from our studies and additional literature, and were synthesized into the new evidence-based implementation model and checklist for personalized dementia care in the community.

Extraction of data led to a composition of an evidence-based model for the implementation of personalized psychosocial care interventions that incorporates core components of personalized care. The model addresses several issues, e.g. how personalized care interventions should be offered and to whom; whether these are able to adapt to personal characteristics and needs of clients and informal caregivers; and whether both organizational management and staff that provide the intervention support personalized care and are able to focus on providing individualized care.

Our model provides a checklist for researchers, professional caregivers, and policy-makers who wish to develop, evaluate, or implement personalized care interventions.

Despite well-documented evidence of the psychological effects of caring for a relative with dementia, little is known about the bereavement experiences of family carers. The aim of this study was to explore the key psychological changes associated with carers’ adjustment to bereavement and “life after care.”

All carers taking part were recruited from a day care center, providing specialist services to people with dementia. We asked carers to describe the key changes associated with psychological adjustment to bereavement through semi-structured qualitative in-depth interviews. Strategies carers used to cope with and adapt to their new role were also explored. All data were thematically analysed.

Thirty-one carers were interviewed. The most frequent emotional reactions to bereavement were feelings of loneliness, loss, void, sadness, anger, and relief. Most carers were able to adapt to their new role, and engaging in pleasant activities was the most frequent strategy used to cope with loss and “life after care.”

Feelings of loneliness and loss are amongst the key emotional reactions shaping carers’ adjustment to bereavement. Most carers are able to adapt to loss; however, a minority experience increased psychological distress after the death of their loved one. A small percentage of carers continues caring for other dependants. Further research is required to identify how carers of people with dementia adapt to bereavement and how this increasing number of individuals can be best supported.

It is necessary to continue to explore the psychometric characteristics of key cognitive screening tests such as the Montreal Cognitive Assessment (MoCA) to diagnose cognitive decline as early as possible and to attend to the growing need of clinical trials involving mild cognitive impairment (MCI) participants. The main aim of this study was to assess which MoCA subtests could best discriminate between healthy controls (HC), participants with MCI, and Alzheimer's disease (AD).

Cross-sectional analysis of 136 elderly with more than four years of education. All participants were submitted to detailed clinical, laboratory, and neuroimaging evaluation. The MoCA, Mini-Mental State Examination (MMSE), the Cambridge Cognitive Examination (CAMCOG), Geriatric Depression Scale (GDS), and Functional Activities Questionnaire (FAQ) were applied to all participants. The MoCA test was not used in the diagnostic procedure.

Median MoCA total scores were 27, 23 and 18 for HC, MCI, and AD, respectively (p < 0.001). Word repetition, inverse digits, serial 7, phrases, verbal fluency, abstraction, and word recall discriminated between MCI and HC participants (p < 0.001). The clock drawing, the rhino naming, delayed recall of five words and orientation discriminated between patients with MCI and AD (p < 0.001). A reduced version of the MoCA with only these items did not improve accuracy between MCI and HC (p = 0.076) or MCI and AD (p = 0.119).

Not all MoCA subtests might be fundamental to clinical diagnosis of MCI. The reduced versions of MoCA did not add diagnostic accuracy.

As the global population ages, it is important that the professional care workforce is well prepared to support the needs of people with dementia. In Australia, the Dementia Behaviour Management Advisory Service (DBMAS) supports people with dementia and their carers through an interdisciplinary team approach. To provide DBMAS Behaviour Consultants with a tool to guide them in their professional development, this project aimed to develop a self-assessment tool to enable self-reflection on clinical competencies required for working in the service and identification of areas where further development would be required.

A multi-stage process was applied in the development of the tool, including review of the relevant literature and focus groups with DBMAS Behaviour Consultants and Team Leaders. The tool encompasses both skills and knowledge in working with people with dementia and caregivers. A pilot study including 14 DBMAS consultants was conducted to assess the utility of the measure and ensure variability of ratings across knowledge and skill areas relative to time working in DBMAS.

The Knowledge and Skills Assessment (KASA) was developed and is now used in DBMAS service both with novice Behaviour Consultants and more experienced staff, and is also being used as an on-line version, accompanied with case vignettes.

The KASA provides a valuable self-assessment tool for professional care staff working in dementia care, but would nevertheless still warrant further testing of its psychometric characteristics.

Delirium is a common neuropsychiatric syndrome that includes clinical subtypes identified by the Delirium Motor Subtyping Scale (DMSS). We explored the concordance between the DMSS and an abbreviated 4-item version in elderly medical inpatients.

Elderly general medical admissions (n = 145) were assessed for delirium using the Revised Delirium Rating scale (DRS-R98). Clinical subtype was assessed with the DMSS (which includes the four items included in the DMSS-4). Motor subtypes were generated for all patient assessments using both versions of the scale. The concordance of the original and abbreviated DMSS was examined.

The agreement between the DMSS and DMSS-4 was high, both at initial and subsequent assessments (κ range 0.75–0.91). Intraclass Correlation Coefficient (ICC) for all three raters for the DMSS was high (0.70) and for DMSS-4 was moderate (0.59). Analysis of the agreement between raters for individual DMSS items found higher concordance in respect of hypoactive features compared to hyperactive.

The DMSS-4 allows for rapid assessment of clinical subtype in delirium and has high concordance with the longer and well-validated DMSS, including over longitudinal assessment. There is good inter-rater reliability between medical and nursing staff. More consistent clinical subtyping can facilitate better delirium management and more focused research effort.

Despite advances in delirium knowledge and the publication of best practice guidelines, uncertainties exist regarding assessment of Delirium Superimposed on Dementia (DSD). An international survey of delirium specialists was undertaken to evaluate current practice.

Invitations to participate in an online survey were distributed by email among members of four international delirium associations with additional publication on their websites. The survey covered the assessment and diagnosis of DSD in clinical practice and research studies. Questions were structured around current practice and attitudes.

The 205 responders were mostly confident that they could detect DSD with 60% rating their confidence at 7 or above on a likert scale of 0 (none) to 10 (excellent). Seventy-six percent felt that Dementia with Lewy Bodies (DLB) was the most challenging dementia subtype in which to diagnose DSD. Several scales were used to assess for the presence of DSD including the Confusion Assessment Method (CAM) (54%), DSM-5 criteria (25%) and CAM-ICU (15%). Responders stated that attention (71%), fluctuation in cognitive status (65%), and arousability (41%) were the most clinically useful features to assess when diagnosing DSD. Motor fluctuations were also deemed important but 61% had no specific test to monitor these.

The largest survey of DSD practice to date demonstrates that despite good levels of confidence in recognizing DSD, there exists a lack of consensus concerning assessment and diagnosis globally. These findings suggest the need for the development of more research leading to precise diagnostic criteria and comprehensive guidelines regarding the assessment and diagnosis of DSD.

The mean age of inpatients with schizophrenia has gradually increased in Japan and the risk of fracture in older schizophrenia patients is elevated. One possible cause may be idiopathic normal pressure hydrocephalus (iNPH). The present study aimed to evaluate the prevalence and symptoms of iNPH in older inpatients with schizophrenia.

We prospectively examined older inpatients with schizophrenia (N = 21, mean age = 70.5 ± 5.9) in a psychiatric ward. We evaluated iNPH symptoms using the idiopathic Normal-Pressure Hydrocephalus Grading Scale (iNPHGS), Timed Up-and-Go test (TUG), Gait Status Scale (GSS), Mini-Mental State Examination (MMSE), and Neuropsychiatric Inventory (NPI). We also evaluated symptoms of schizophrenia using the Brief Psychiatric Rating Scale (BPRS) and Drug-Induced Extrapyramidal Symptoms Scale (DIEPSS). We conducted cerebrospinal fluid (CSF) tap tests for patients with possible-iNPH.

In total, three (14.3%) patients were diagnosed with possible iNPH: age, GS-Gait, GS-Cognition, TUG, 10-meter walking test, GSS, and DIEPSS were significantly increased in these compared to patients without iNPH; however, GS-Urine, MMSE, NPI, and BPRS did not differ significantly. Probable iNPH was diagnosed for two (9.5%) patients because of positive CSF tap tests.

The prevalence of possible and probable iNPH in older patients with schizophrenia was much higher than that reported for older people without mental illness. Of the symptoms evaluated with the tests employed, only gait disturbances, particularly walking speed, distinguished schizophrenia patients with iNPH. These findings suggest that we should pay more attention to the possibility of iNPH in older patients with schizophrenia.
