Non-pharmacological interventions may have a role in both the prevention and slowing down of disease progression in Alzheimer's disease (AD). The role of exercise in disease prevention, for example, has been extensively evaluated in large epidemiological studies. Much less is known about the potential benefit of exercise in patients already diagnosed with AD. It was therefore the aim of this systematic review to assess the effectiveness of exercise in attenuating cognitive decline within AD.

A systematic review was conducted statistically accompanied by a meta-analysis. Publications between January 1991 and October 2012 were identified by searching the electronic databases PubMed, Science Direct, Web of Knowledge, and PsychINFO. Selected studies required AD patients to take part in an exercise-based randomized controlled trial (RCT) and have a cognitive outcome measure.

Six RCTs were identified that exclusively considered the effect of exercise in AD patients. Exercise generally had a positive effect on rate of cognitive decline in AD. A meta-analysis found that exercise interventions have a positive effect on global cognitive function, 0.75 (95% CI = 0.32–1.17).

From the six studies reviewed, the evidence suggests that exercise can have a positive effect on rate of cognitive decline in AD. However, the variation between study designs makes conclusions regarding the optimum intervention on cognitive outcome in AD difficult. Well-designed and powered RCTs are still needed to ascertain the efficacy of exercise in slowing down cognitive impairment in AD patients. However, a positive initial indication for exercise efficacy justifies such efforts.

In clinical practice, Second Generation Antipsychotics (SGAs) are often used as first-line treatment for the Behavioral and Psychological Symptoms of Dementia (BPSD) in older adults due to their fewer neurological adverse events and similar effectiveness compared with First Generation Antipsychotics (FGAs). SGAs, however, are associated with more severe metabolic side effects (weight gain, hyperglycemia, diabetes risk, and hyperlipidemia) than FGAs are. In general, older patients, especially those affected by dementia, are at increased risk for malnutrition, and tend to have lower basal metabolism and reduced liver and kidney function. However, little is known about the metabolic side effects of antipsychotic drugs in this population.

A comprehensive review of the literature published between January 1996 and December 2012 investigating the metabolic side effects related to FGAs and SGAs use in old patients affected by dementia.

Antipsychotic drugs currently used to treat BPSD in subjects with mild to moderate dementia are associated with weight gain. Currently, there are insufficient data to support a causal relationship between the use of FGAs and SGAs and changes in glucose homeostasis or lipid metabolism in older persons affected by severe dementia (MMSE <14).

A possible association between antipsychotic drugs use and weight gain might exist, in particular in subjects with mild to moderate dementia whereas no significant effects are demonstrated regarding glucose homeostasis and lipid metabolism. The antipsychotic drugs potential for causing metabolic abnormalities in older patients requires further specifically designed studies. Clinicians must be aware of this possibility even if the shorter periods of treatment administered in late-life might not be as harmful as it is in younger individuals.

The objective of this study was to explore the factor structure of a shortened ten-item Center for Epidemiologic Studies Depression Scale (CES-D 10) used in a national survey in China.

This secondary research is based on the wave I (2011) of the China Health Aging Retirement and Longevity Study (CHARLS). CHARLS recruited a nationally representative community sample of households with members aged 45 years or above. A subsample of 742 respondents aged 60 years and older were used for this study. Confirmatory factor analyses were conducted to test three competing models and determine the best-fit model for the elderly Chinese sample. Factorial invariance across gender was also examined. R2 coefficient was used to measure the reliability of each item.

Confirmatory factor analysis supported the two-factor model as having the best fit. Depressive affect and somatic symptoms were the first factor while positive affect was loaded as the second factor. The multi-group analysis showed that the two-factor structure varied across the male and female groups in China (χ2 (df = 86) = 144.13, p < 0.001). Moreover, gender differences were indicated by individual item reliability scores, mean score, and prevalence rate of depressive symptoms.

The CES-D 10 Scale indicated adequate reliability and validity for the community-dwelling older population in China. In addition, the data revealed that perception and expression of depressive feelings was different between male and female elderly people.

This study aimed to assess the prevalence, incidence, and persistence of suicidal ideation (SI), and to investigate the psychosocial factors associated with these.

A total of 1,204 community dwelling elderly adults aged 65 years or older were evaluated at baseline, 909 (75%) of whom were followed two years later. The presence of SI was identified using the questions from the community version of the Geriatric Mental State (GMS) diagnostic schedule (GMS B3) at both baseline and follow-up interviews. Baseline measures included demographic status, years of education, rural/urban residence, accommodation, past and current occupation, monthly income, marital status, stressful life events, social support deficits, number of physical illnesses, severity of pain, physical activity, disability, depressive symptoms, anxiety, insomnia, cognitive function, alcohol consumption, and smoking.

Baseline SI prevalence, follow-up incidence (SI rate at follow-up of 805 elderly subjects who did not have SI at baseline), and persistence (SI rate at follow-up of 104 elderly subjects who had SI at baseline) were 11.5%, 9.6%, and 36.5%, respectively. Baseline SI was independently associated with no current employment, lower monthly income, stressful life events, more severe pain, presence of disability, depressive symptoms, and smoking. Incident SI was independently predicted by baseline unmarried status, social support deficit, severe pain, presence of depressive symptoms, and smoking. Persistent SI was independently predicted by baseline stressful life events and depressive symptoms.

Depressive symptoms were independently associated with prevalent, incident, and persistent SI, but other predictors varied according to incidence and persistence outcomes.

Occupation remains an unmet need in long-term dementia care. To increase residents’ occupation, knowledge of types of occupation related to wellbeing, and organizational and environmental characteristics encouraging involvement in these types of occupation, is indispensable.

In this explorative study, Dementia Care Mapping was used to study involvement in different types of occupation and wellbeing among 57 residents of 10 dementia care facilities. For each type of occupation, mean experienced wellbeing was studied. Occupation types with high mean wellbeing scores were classified as “wellbeing-enhancing occupation.” Care facilities were ranked according to the mean time residents spent in types of wellbeing-enhancing occupation. Using information on staff-to-resident ratio, individual space, and items of the Physical Environment Evaluation Component of Dementia Care Mapping, organizational and environmental characteristics of the facilities were compared to study their relationship with wellbeing-enhancing occupation.

Reminiscence, leisure, expression, and vocational occupation had greatest potential to enhance wellbeing, but these types were seldom offered. Much variation existed in the extent to which wellbeing-enhancing occupation was provided. Long-term care facilities that did so more frequently generally had a more homelike atmosphere, supported social interaction through the environment, and had no central activity program.

This study suggests that it is possible to engage residents in wellbeing-enhancing occupation, within current means of budget and staff. The physical environment and care organization might play a role, but the key factor seems to equip staff with skills to integrate wellbeing-enhancing occupation into care practice.

Neuropsychiatric symptoms (NPS) are prevalent in nursing-home (NH) patients with dementia, but little is known about the long-term course of these symptoms.

In this study, 931 NH patients with dementia took part in a prospective cohort study with four assessments over a 53-month follow-up period. NPS and level of dementia were assessed with the Neuropsychiatric Inventory scale and the Clinical Dementia Rating scale, respectively.

Mild, moderate, and severe dementia was present in 25%, 33%, and 42%, respectively. There was an increase in the severity of the dementia from the first to the fourth assessment. Agitation, irritability, disinhibition, and apathy were the most prevalent and persistent symptoms during the study period. The affective subsyndrome (depression and anxiety) became less severe, whereas the agitation subsyndrome (agitation/aggression, disinhibition, and irritability) and apathy increased in severity during the follow-up period. More severe dementia was associated with more severe agitation, psychosis, and apathy, but not more severe affective symptoms. Mild dementia was associated with an increase in the severity of psychosis, whereas moderate or severe dementia was associated with decreasing severity of psychosis over the follow-up period.

Nearly all the patients experienced clinically significant NPS, but individual symptoms fluctuated. Affective symptoms became less severe, while agitation and apathy increased in severity. An increase in dementia severity was associated with an increase in the severity of agitation, psychosis, and apathy, but not affective symptoms. The results may have implications when planning evaluation, treatment, and the prevention of NPS in NH patients.

Caregiver efficacy for managing the behavioral and psychological symptoms of dementia (BPSD) is an important determinant of family caregiver stress and burden. This study aims to develop a measure of caregiver efficacy for responding to BPSD and to evaluate its psychometric properties.

The Caregiver Efficacy Scale adds an item for caregiver confidence in managing BPSD to each domain of the Neuropsychiatric Inventory (NPI). The validity, internal consistency, and factor structure of the scale were evaluated in 245 family caregivers.

The results provide adequate support for the validity and reliability of the Caregiver Efficacy Scale. The internal consistency was found to be adequate (Cronbach's α = 0.79) and the scale demonstrated good concurrent, construct, and criterion validity. As expected, performance on the Caregiver Efficacy Scale was associated with all dimensions of the NPI, including BPSD frequency (r = 0.869, p < 0.01) and severity (r = 0.883, p < 0.01), and negative outcomes, including negative affect (r = 0.411, p < 0.01), depression (r = 0.362, p < 0.01), anxiety (r = 0.376, p < 0.01), and distress (r = 0.865, p < 0.01).

The Caregiver Efficacy Scale might have clinical implications in facilitating the development of improved caregiver interventions for dealing with BPSD, allowing interventions to be tailored according to individual caregiver needs, and also in evaluating the effectiveness of interventions aimed at improving caregiver self-efficacy for managing BPSD.

This exploratory study investigated the associations of individual characteristics of both persons with dementia and family caregivers with the nutritional status of caregivers.

This cross-sectional study was conducted at home by psychogerontologist within the frame of a community gerontological center in rural areas of south west France. The study participants comprised 56 community-dwelling persons with dementia (mean 80.7 years, SD 6.5) and 56 family caregivers (mean 70.9 years, SD 11.0). Persons with dementia were assessed with Mini-Mental State Examination (MMSE), Basic Activities Of Daily Living (ADL), Instrumental ADL (IADL), and NeuroPsychiatric Inventory (NPI), and family caregivers with the Burden Interview (Zarit scale), the State-Trait Anxiety Inventory (STAI Y-B), the Center for Epidemiologic Studies Depression Scale (CES-D), the emotional impact measure of NPI and the Autonomy, Gerontology and Group Resources scale (AGGIR scale). For both, nutritional status was evaluated using the Mini Nutritional Assessment (MNA®).

Among family caregivers, 32.1% were at risk of malnutrition and 5.4% were malnourished, and among people with dementia, 58.9% and 23.2%, respectively. NPI severity score of apathy of persons with dementia (Beta = −0.342, p = 0.001), dependency on AGGIR scale (Beta = −0.336, p = 0.002), and CES-D score of caregivers (Beta = −0.365, p = 0.001) were associated with caregivers’ MNA score (Adjusted R2 = 0.480, p < 0.001).

These preliminary findings emphasize the need for routine assessment of depressive symptoms, functional and nutritional status in dementia family caregivers, and confirm the value of investigating caregivers’ nutritional risk through an integrative view including psychosocial approach.

Very limited literature exists on the care and course of patients with Korsakoff syndrome (KS) living in long-term care facilities (LTCFs). Even less literature can be found on the pharmacological treatment of behavioral symptoms of KS. The purpose of the present study was to describe baseline characteristics, comorbidity, and the use of psychotropic drugs in institutionalized patients with KS.

In this cross-sectional descriptive study, 556 patients were included living in ten specialized care units in Dutch nursing homes. Data were collected by means of a retrospective chart review.

The majority of patients were men (75%) and single (78%) with a mean age on admission of 56.7 years (SD 8.9, range 29.8–85.3). Mean length of stay was 6.0 years (SD 5.4, range 0.2–33.3). Sixty-eight percent of patients suffered from at least one somatic disease and 66% from at least one extra psychiatric disorder. One or more psychotropic drugs were prescribed to 71% of patients with a great variation in prescription patterns between the different nursing homes.

Patients with KS depending on long-term care usually have comorbidity in more than one domain (somatic and psychiatric). The indications for prescribing psychotropic drugs are in many cases unclear and it seems probable that they are often given to manage challenging behavior. Longitudinal studies on the evidence for this prescription behavior and possible alternatives are recommended.

We investigate to what extent pain in older individuals is predicted by on the one hand chronic morbidity as a resistance deficit, and on the other hand psychological resistance resources and the sense of coherence. For the first time, we tested the salutogenic hypothesis that the sense of coherence mediates the relationship between resources/deficits and pain.

In our questionnaire study, we assessed selected psychological resistance resources (self-esteem, generalized self-efficacy, optimism, and social support), the number of self-reported medical diagnoses of chronic illness, the sense of coherence, and pain (SF-36 Bodily Pain subscale) in a sample of 387 older persons (at the mean age of 73.8 years).

Using hierarchical regression, we found that morbidity and sense of coherence were the only significant predictors of pain, with morbidity showing the strongest effect. Using path analysis, the sense of coherence was a mediator of the relationship between resistance resources/deficits and pain.

With respect to our analytical model, in which pain experience was the criterion variable, morbidity and the sense of coherence are important predictors of pain. Moreover, we found evidence for the salutogenic idea that the sense of coherence represents a mediator variable as it pools resistance/deficits influences on pain. We recommend a prospective design to explore these assumed causal chains in future research.

The development of instruments to measure aging attitudes is an essential part of research into the role of individual differences in the aging process, giving clarification to the relationship between attitudes and behavior across the lifespan. Here we test the structural validity of Lasher and Faulkender's (1993) Anxiety about Aging Scale (AAS), and explore measurement invariance across age and gender.

A sample of 783 adults (42% females) age ranging from 20 to 97 years (M = 57.3, SD = 13.66) participated.

The first-order four-factor AAS model reflecting the original Lasher and Faulkender (1993) structure showed a better fit to the data than the second-order model. Measurement invariance for both gender and age groups (young adults 20–44 years; mid-aged adults 45–64 years, older adults 65+ years old) was found for three of the factors, but not for all items in the Fear of Losses factor. Structural covariance inequality between the Fear of Losses and Physical Appearance factors was shown between males and females.

Findings indicate that the original AAS measures four distinct dimensions of anxiety about aging. These dimensions were shown to be generally comparable across age and gender, indicating that the AAS is a suitable measure for providing meaningful comparison of anxiety about aging across the lifespan. The exception is the Fear of Losses factor, where items may have differential meanings across groups based on cultural and social attitudes regarding aging and gender.

The impact of stressful life events as a risk factor of dementia diseases is inconclusive. We sought to determine whether stressful negative life events are associated with incidental dementia in a population-based study with long-term follow-up. We also tested the hypothesis that the occurrence of positive life events could mitigate or overcome the possible adverse effects of negative life events on dementia conversion.

The study involved 2,462 dementia-free participants aged 55 years and older. Information on life events was ascertained at baseline from a comprehensive Life Event Inventory, which included 56 questions about specific life events. For each life event, the emotional impact (both positive and negative) and emotional adjustment were asked for.

During follow-up, 423 participants developed dementia; of these, 240 developed Alzheimer's disease (AD). Cox regression analysis showed no association between the total number of negative life events and the incidence of dementia when adjusted solely for age and gender (hazard ratio = 0.97, 95% CI = 0.92–1.02), or with multiple adjustments for a range of covariates (hazard ratio = 0.96, 95% CI = 0.91–1.01). Similarly, neither emotional impact nor emotional adjustment to these life events was associated with incident dementia. A separate analysis of AD did not alter the results.

The result of this population-based study finds no association between negative or positive life events and dementia. Accordingly, our results reject the hypothesis that stressful life events trigger the onset of dementia diseases.

Frailty is highly prevalent in older people, but its association with cognitive function is poorly understood. The aim of this study was to examine the association between cognitive function and frailty in community-dwelling older adults.

Data were from the 2008 Living Profiles of Older People Survey, comprising 10,388 nationally representative sample aged 65 years and older living in the community in South Korea. Frailty criteria included unintentional weight loss, exhaustion, weakness, low physical activity, and slow walking speed. Cognitive function was assessed using the Korean version of the Mini-Mental State Examination. Multinomial logistic regression models were constructed with frailty status regressed on cognitive impairment and subdomains of cognitive function, adjusting for covariates.

Those who were frail showed a higher percentage of cognitive impairment (55.8% in men, 35.2% in women) than those who were not (22.1% in men, 15.6% in women). Cognitive impairment was associated with an increased risk of frailty in men (odds ratio (OR) = 1.81, 95% confidence interval (CI): 1.25–2.60) and women (OR = 1.69, 95% CI: 1.25–2.30) even after controlling for all covariates. Among the subdomains of cognitive function, time orientation, registration, attention, and judgment were associated with a lower likelihood of frailty in both men and women after adjusting for confounders. Among women higher scores on recall, language components, and visual construction were also significantly associated with lower odds of frailty.

Cognitive impairment was associated with a higher likelihood of frailty in community-dwelling older men and women. Total scores and specific subdomains of cognitive function were inversely associated with frailty.

The changing demographics of societies mean that medical students worldwide must be sufficiently prepared to care competently for patients with dementia through development of appropriate knowledge, skills, and attitudes. No previous research had explored undergraduate medical students’ attitudes toward people with dementia.

An adapted version of the Approaches to Dementia Questionnaire (ADQ) was completed by 501 medical undergraduates in years 1, 3, and 5 of their degree programs in the UK and Malaysia. Non-parametric statistical analysis focused on any differences between year groups and geographical locations.

The mean ADQ response indicated a generally positive attitude across the sample, comparable with other healthcare professionals previously surveyed. Year 3 and year 5 students expressed significantly more positive attitudes than year 1 students. Year 1 students based in the UK expressed significantly more positive attitudes than year 1 student based in Malaysia, but there were no significant differences between year 3 students based in different locations.

The more positive attitudes found amongst year 3 and year 5 students compared to year 1 may be a result of teaching emphasizing a person-centered approach. The differences between entry-level students from Malaysia and the UK may reflect variance in cultural norms and expectations, or the ADQ's “Western” origin. Medical schools aiming to equip students with dementia-specific skills and knowledge can draw on the generally positive attitudes found in this study.
