Very old individuals seem to present an admirable capacity to overcome adversities and adapt to the challenges of advanced age. However, studies focusing successful pattern of centenarians found that they may easily fail to be categorized as successful agers when objective criteria are applied. The present study examines if centenarians can be considered successful agers. Following Rowe and Kahn's successful aging model, the primary goal was to clarify whether centenarians are able to be successful agers according to objective and subjective criteria of no major disease and disability, high cognitive and physical functioning and engagement with life. The second goal was to investigate whether socio-demographic factors, psychological, social, and economic resources are related to objective and subjective successful aging profiles.

We examined different profiles of successful aging in a high selected sample of individuals aged 100 and more years old from the population-based Oporto Centenarian Study.

Main findings reveal that centenarians do not represent the prototype of successful aging, but self-ratings demonstrate that many of them feel successful, despite not being objectively considered as so. Those who were considered successful agers presented higher values of self-efficacy, hope, and purpose in life, as well as few difficulties in covering financial expenses.

As a basis for strengthening the existing model, the value of subjectivity should be explored and psychological resources promoted in interventions to foster positive adaptation in very old age.

The prevalence of dementia is increasing in Asia than in any other continent. However, the applicability of the existing cognitive assessment tools is limited by differences in educational and cultural factors in this setting. We conducted a systematic review of published studies on cognitive assessments tools in Asia. We aimed to rationalize the results of available studies which evaluated the validity of cognitive tools for the detection of cognitive impairment and to identify the issues surrounding the available cognitive impairment screening tools in Asia.

Five electronic databases (CINAHL, MEDLINE, Embase, Cochrane Library, and Science Direct) were searched using the keywords dementia Or Alzheimer Or cognitive impairment And screen Or measure Or test Or tool Or instrument Or assessment, and 2,381 articles were obtained.

Thirty-eight articles, evaluating 28 tools in seven Asian languages, were included. Twenty-nine (76%) of the studies had been conducted in East Asia with only four studies conducted in South Asia and no study from northern, western, or central Asia or Indochina. Local language translations of the Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) were assessed in 15 and six studies respectively. Only three tools (the Korean Dementia Screening Questionnaire, the Picture-based Memory Intelligence Scale, and the revised Hasegawa Dementia Screen) were derived de novo from Asian populations. These tools were assessed in five studies. Highly variable cut-offs were reported for the MMSE (17–29/30) and MoCA (21–26/30), with 13/19 (68%) of studies reporting educational bias.

Few cognitive assessment tools have been validated in Asia, with no published validation studies for many Asian nations and languages. In addition, many available tools display educational bias. Future research should include concerted efforts to develop culturally appropriate tools with minimal educational bias.

The prevalence and factors associated with delays in help seeking for people with dementia in China are unknown.

Within 1,010 consecutively registered participants in the Clinical Pathway for Alzheimer's Disease in China (CPAD) study (NCT01779310), 576 persons with dementia (PWDs) and their informants reported the estimated time from symptom onset to first medical visit seeking diagnosis. Univariate analysis of general linear model was used to examine the potential factors associated with the delayed diagnosis seeking.

The median duration from the first noticeable symptom to the first visit seeking diagnosis or treatment was 1.77 years. Individuals with a positive family history of dementia had longer duration (p = 0.05). Compared with other types of dementia, people with vascular dementia (VaD) were referred for diagnosis earliest, and the sequence for such delays was: VaD < Alzheimer's disease (AD) < frontotemporal dementia (FTD) (p < 0.001). Subtypes of dementia (p < 0.001), family history (p = 0.01), and education level (p = 0.03) were associated with the increased delay in help seeking.

In China, seeking diagnosis for PWDs is delayed for approximately 2 years, even in well-established memory clinics. Clinical features, family history, and less education may impede help seeking in dementia care.

Few studies have estimated care burden in large, representative, multi-ethnic Asian population-based informal caregivers of older adults with care needs. This study describes informal caregivers’ care participation for a population-based sample of older adults with care needs in Singapore, investigates differences by dementia status, and examines correlates of caregivers’ burden.

Data collected from 693 pairs of older adults, aged 60 to 100 years, having any care needs, and their informal caregivers, who were aged 21 to 88 years, closely involved in their care and “knew the older resident best,” and were interviewed during a cross-sectional national survey, were used. Clinical characteristics of older adults, including behavioral and psychological symptoms of dementia (BPSD) and dementia diagnosis, care needs, and socio-demographic characteristics of participants were obtained. Care burden was assessed with the Zarit Burden Interview.

Informal caregivers’ participation was highest in activities related to communication (35.1%), feeding (32%), and bathing (21.1%). Among the older adults with any care need, 356 (51.4%) had dementia. Care burden was significantly associated with married caregivers (odds ratio (OR) 2.4 vs. never married), when their relative belonged to a younger cohort (OR 2.5 vs. >84 years), needed care much of the time (OR 2.5 vs. no care needed), exhibited BPSD (OR 3.5 vs. no BPSD), and had dementia (OR 2.52 vs. no dementia).

Factors related to older adults – more care needs, presence of BPSD, and dementia – were significant contributors to informal caregivers’ burden, and these should be considered while planning interventions to alleviate care burden.

The Family Group Conference (FGC) is an approach to partnership working which brings together service users, their support network and care professionals in a family-led decision making forum. Evidence, though limited, indicates that that FGC can enhance outcomes for service providers and their users. This study aimed to evaluate the impact of the pilot FGC service, delivered to people with dementia and their families, in terms of the experience of care provision by families and care professionals involved in the project.

Focus group interviews were conducted with families and professionals participating in the pilot intervention.

FGC was perceived as having the potential to positively impact service users, their families, service providers and the wider culture of care. However, despite an overall positive evaluation the participants identified a number of challenges related to service implementation. Both the opportunities and challenges identified in this study are discussed in the context of the existing international evidence base.

This study contributes to a better understanding of the applicability of FGC as a strategy to support people with dementia and their families. Although promising in terms of potential outcomes for service users and providers, FGC presents challenges which need to be carefully managed in order to secure maximum benefit to all parties.

We aimed to obtain a better understanding of how different aspects of patient functioning affect key cost and caregiver outcomes in Alzheimer's disease (AD).

Baseline data from a prospective observational study of community-living AD patients (GERAS) were used. Functioning was assessed using the Alzheimer's Disease Cooperative Study – Activities of Daily Living Scale. Generalized linear models were conducted to analyze the relationship between scores for total activities of daily living (ADL), basic ADL (BADL), instrumental ADL (IADL), ADL subdomains (confirmed through factor analysis) and individual ADL questions, and total societal costs, patient healthcare and social care costs, total and supervision caregiver time, and caregiver burden.

Four distinct ADL subdomains were confirmed: basic activities, domestic/household activities, communication, and outside activities. Higher total societal costs were associated with impairments in all aspects of ADL, including all subdomains; patient costs were associated with total ADL and BADL, and basic activities subdomain scores. Both total and supervision caregiver hours were associated with total ADL and IADL scores, and domestic/household and outside activities subdomain scores (greater hours associated with greater functional impairments). There was no association between caregiver burden and BADL or basic activities subdomain scores. The relationship between total ADL, IADL, and the outside activities subdomain and outcomes differed between patients with mild and moderate-to-severe AD.

Identification of ADL subdomains may lead to a better understanding of the association between patient function and costs and caregiver outcomes at different stages of AD, in particular the outside activities subdomain within mild AD.

Psychological stress associated with caregiving is thought to underlie the high incidence of hypertension, ischemic heart disease, and mortality, as well as reduced immune function, among caregivers of dementia patients. Here, we examined the effects of periodic leisure activities performed by caregivers of dementia patients with care recipients at home on perceived care burden and levels of stress hormones.

Participants were 42 caregivers aged ≥ 65 years of patients diagnosed with Alzheimer's dementia. They were randomly assigned to intervention and non-intervention groups. The intervention group underwent a leisure activity program (30 min/3 times/week for 24 weeks) with the care recipient, and the control group underwent normal care activities.

The Zarit Burden Interview (ZBI) score, a subjective indicator of care burden, significantly decreased after intervention in the intervention group (p < 0.05), whereas no difference was observed in the control group. No significant changes were observed in adrenaline, noradrenaline, dopamine, and cortisol levels in both groups.

The lack of changes in stress hormone levels despite a decrease in subjective care burden in the intervention group might be explained by the effects of the chosen leisure activity on the neuroendocrine system. Our findings suggest that periodic leisure activities can reduce perceived care burden among caregivers of dementia patients. However, in order to evaluate accurately the effects of leisure activities of the present study, long-term follow-up of both caregivers and care recipients is necessary. The Nagoya University Department of Medicine Ethics Committee Clinical Trials Registry Number is 1290.

Caregiver burden is a significant issue in the treatment of dementia and a known contributor to institutionalization of patients with dementia. Published data have documented increased caregiver burden in behavioral variant frontotemporal dementia (bvFTD) compared to Alzheimer's disease (AD). Another atypical dementia with high-perceived caregiver burden is sporadic Creutzfeldt–Jakob disease (sCJD), but no formal studies have assessed this perception. The aim of this study was to compare caregiver burden across atypical dementia etiologies.

76 adults with atypical dementia (young-onset AD [YOAD], bvFTD, language variant FTD [lvFTD], and sCJD) were administered an abbreviated version of the Zarit Burden Interview (ZBI), Neuropsychiatric Inventory (NPI-Q), and other assessment instruments during a five-year time period at Johns Hopkins Hospital (JHH). A Cox regression model examined differences between disease categories that impact mean ZBI scores.

Mean ZBI scores were significantly different between dementia etiologies, with bvFTD and sCJD having the highest caregiver burden (p = 0.026). Mean NPI-Q caregiver distress scores were highest in bvFTD and sCJD (p = 0.002), with sCJD and bvFTD also having the highest number of endorsed symptom domains (p = 0.012). On regression analyses, an interactive variable combining final diagnosis category and NPI-Q total severity score demonstrated statistically significant differences in mean ZBI scores for sCJD and bvFTD.

This study demonstrates that bvFTD and sCJD have increased levels of caregiver burden, NPI-Q caregiver distress, total severity scores, and number of endorsed symptom domains. These results suggest that higher caregiver burden in bvFTD and sCJD are disease specific and possibly related to neuropsychiatric symptoms.

In spite of the recognized physical and psychosocial effects of caring for patients with Parkinson's disease (PD), caregiver burden (CB) in this setting is poorly understood. The objective of this research was to identify factors that were associated with CB in an Australian population of PD caregivers using a novel instrument – the Parkinson's Disease Caregiver Burden (PDCB) questionnaire.

Fifty patient–caregiver couples were recruited from three movement disorders clinics in Melbourne, Australia. Burden on caregivers was rated using the PDCB questionnaire. Burden scores were correlated with patient factors, including motor symptom severity (Unified Parkinson's Disease Ratings Scale and Hoehn & Yahr (H&Y) scale), patient cognition (Neuropsychiatry Unit Cognitive Assessment Tool; NUCOG), presence of impulsive and compulsive behaviors (Questionnaire for Impulsive–Compulsive Disorders in Parkinson's disease), and patient olfaction. Caregiver and patient demographics, as well as results for depression and anxiety (Hospital Anxiety and Depression Scale; HADS), were also examined for their relationship with CB.

H&Y stage, depression or anxiety in either caregiver or patient, and decreased patient NUCOG score were significantly associated with higher PDCB score. Multiple linear regression analysis identified caregiver and patient depression score and patient score for the visuoconstructional subscale of NUCOG to predict burden score. In addition, disease duration, duration of caregiving, and increased hours per day spent in giving care were significantly associated with increased burden.

We found psychiatric and cognitive factors to be the most relevant factors in the perception of burden in PD caregivers. On top of this, we found deficits in the domain of visuoconstruction predicted burden – a relationship not yet described in literature. Targeting depression and anxiety in this setting as well as identifying caregivers at high risk of burden may give clinicians the chance to optimize care of patients with PD through the caregiver.

This is a case-control study to investigate the prevalence, characteristics, and risk factors of pain in patients with Parkinson's disease (PD).

A total of 200 PD patients from eastern China were enrolled in our study. Accordingly, 200 healthy elderly adults were recruited as controls. The characteristics of pain were collected by using the Visual Analog Scale, Brief Pain Inventory (BPI), SF-36 Bodily Pain Scale, Unified Parkinson's Disease Rating Scale, Hoehn–Yahr Scale (H-Y), Hamilton Depression Scale, and Leeds Assessment of Neuropathic Symptoms and Signs.

Of the 200 PD patients, pain was complained by 106 patients (53%). According to the SF-36 Bodily Pain Scale, pain morbidity in PD patients was significantly higher than in the control group. The average pain during last 24 h measured by the BPI was 2.67. About 76% of PD patients were found to have one pain type, 21.7% were having two pain types, and 1.9% had three pain types. Further, 69.8% of these patients were presented with musculoskeletal pain, 4.7% with dystonic pain, 22.6% with radicular-neuropathic pain, 20.8% with central neuropathic pain, and 9.4% with akathisia pain. The onset age and depression were the most significant predictors of pain in PD patients (p < 0.05). However, there was no significant association between pain and gender, age, disease duration, or severity of the disease. Only 5.7% of PD patients with pain received treatment in this study.

Pain is frequent and disabling, independent of demographic and clinical variables, and is significantly more common in PD patients.

Intra-individual variability (IIV) and the change of attentional functions have been reported to be susceptible to both healthy ageing and pathological ageing. The current study aimed to evaluate the IIV of attention and the age-related effect on alerting, orienting, and executive control in cognitively healthy older adults.

We evaluated 145 Chinese older adults (age range of 65–80 years, mean age of 72.41 years) with a comprehensive neuropsychological battery and the Attention network test (ANT). A two-step strategy of analytical methods was used: Firstly, the IIV of older adults was evaluated by the intraindividual coefficient of variation of reaction time (ICV-RT). The correlation between ICV-RT and age was used to evaluate the necessity of subgrouping. Further, the comparisons of ANT performance among three age groups were performed with processing speed adjusted.

Person's correlation revealed significant positive correlations between age and IIV (r = 0.185, p = 0.032), age and executive control (r = 0.253, p = 0.003). Furthermore, one-way ANOVA comparisons among three age groups revealed a significant age-related disturbance on executive control (F = 4.55, p = 0.01), in which oldest group (group with age >75 years) showed less efficient executive control than young-old (group with age 65–70 years) (Conventional score, p = 0.012; Ratio score, p = 0.020).

Advancing age has an effect on both IIV and executive attention in cognitively healthy older adults, suggesting that the disturbance of executive attention is a sensitive indicator to reflect healthy ageing. Its significance to predict further deterioration should be carefully evaluated with prospective studies.

In China, as is the case in most of the world, family is the largest source of support for frail older adults. Confucian filial piety expectations hold children-in particular sons-responsible for the care of aging parents in China. During the course of caregiving, in addition to positive feelings, the caregiver may feel overwhelmed, entrapped, and worried about their performance, which can have negative health consequences. The purpose of this exploratory study is to examine one dimension of caregiver burden “worry about performance” (WaP) and investigate whether variables inspired by Pearlin's Stress Process Model help to explain the variation of WaP, so that at-risk caregivers can be identified and supported.

Multiple regression was used to analyze CLHLS data from 895 Chinese adult children providing care for their oldest old parent in eight coastal provinces in China. WaP was measured by two items from the Zarit Burden Inventory. Independent variables representing concepts from Pearlin's Stress Process Model and control variables were included in the models.

Compared to a model of control variables only, using independent variables inspired by Pearlin's Stress Process Model increased the ability to explain the variation in WaP by three fold to 14%. The following variables increased WaP: parent's IADL level, the amount of time spent caregiving, being a daughter, reporting an emotionally close relationship with the parent, sharing a residence with the parent.

Despite not being able to fully operationalize Pearlin's Model with this dataset, analyzing variables that represent concepts from the model was useful in increasing the ability to explain the variation in WaP. Results suggest that caregiver support directed at daughters may be particularly beneficial.

Age-related cognitive decline is common and well-documented. Cognitive speed of processing training (SOPT) has been shown to improve trained abilities (Useful Field of View; UFOV), but transfer to individual non-trained cognitive outcomes or neuropsychological composites is sparse. We examine the effects of SOPT on a composite of six equally weighted tests – UFOV, Trail-making A and B, Symbol Digit Modality, Controlled Oral Word Association, Stroop Color and Word, and Digit Vigilance.

681 patients were randomized separately within two age-bands (50–64, ≥ 65) to three SOPT groups (10 initial hours on-site, 10 initial hours on-site plus 4 hours of boosters, or 10 initial hours at-home) or an attention-control group (10 initial hours on-site of crossword puzzles). At one-year, 587 patients (86.2%) had complete data. A repeated measures linear mixed model was used.

Factor analysis revealed a simple unidimensional structure with Cronbach's α of 0.82. The time effect was statistically significant (p < 0.001; ηp2 = 0.246), but the time by treatment group (p = 0.331), time by age-band (p = 0.463), and time by treatment group by age-band (p = 0.564) effects were not.

Compared to the attention-control group who played a computerized crossword puzzle game, assignment to 10–14 hours of SOPT did not significantly improve a composite measure of cognitive abilities.

Polypharmacy is common among older persons who are also vulnerable to side effects. We aimed to characterize patients who on admission to a geriatric psychiatric hospital had major medication side effects interfering with daily performance.

Cross-sectional cohort study of patients consecutively admitted to a geriatric psychiatric hospital from 2006, 06 December to 2008, 24 October. The UKU side effect rating scale was performed, and patients were divided into those with no/minor side effects versus those with major side effects. Blood levels of 56 psychotropic drugs and 27 safety laboratory tests were measured upon admission.

Of 206 patients included in the analysis, 70 (34%) had major side effects related to drug treatment. The most frequent side effects were asthenia (31%), reduced salivation (31%), concentration difficulties (28%), memory impairment (24%), and orthostatic dizziness (18%). The significant characteristics predicting major side effects were female gender (OR = 2.4, 95% confidence interval (CI) = 1.1–5.5), main diagnosis of affective disorder (OR = 4.3, 95% CI = 1.5–12.3), unreported use of psychotropic medications (OR = 2.0, 95% CI = 1.0–4.1), a higher number of reported psychotropic medications (OR = 1.7, 95% CI = 1.2–2.3), a higher number of reported medications for somatic disorders (OR = 1.2, 95% CI = 1.1–1.5), and a higher score on the Charlson comorbidity index (OR = 1.2, 95% CI = 1.0–1.4) (r2 = 0.238, p < 0.001).

Clinicians should be especially aware of side effects related to drug treatment in geriatric psychiatric female patients with a high use of psychotropic and other medications and somatic comorbidity. Unreported use of psychotropic medications was also related to the risk for side effects, and clinicians should make an effort to ascertain all medications taken by geriatric psychiatric patients.

Individuals with Lewy body dementia (LBD) typically exhibit impairments in attentional and executive function. Current pharmacological treatments have limited efficacy, with associated side effects. Transcranial direct current stimulation (tDCS) may represent an alternative treatment, as cognitive improvements have been demonstrated in healthy individuals. However, no studies to date have assessed the feasibility of tDCS in an LBD population. The aim of this preliminary study, therefore, was to assess the tolerability of tDCS, as well as its effects upon attentional and visuoperceptual performance, in LBD patients.

Thirteen participants completed attentional (simple reaction time, choice reaction time, and digit vigilance) and forced-choice visuoperceptual (angle and motion perception) tasks before and after one 20-min session of active tDCS (0.08 mA/cm2). The anodal electrode was applied to the left dorsolateral prefrontal cortex and the cathodal electrode was applied to the right deltoid. Attentional (task accuracy and reaction time to correct answers) and visuoperceptual (task accuracy and difficulty) outcome measures were compared using paired t-tests.

All participants tolerated stimulation and did not report any side effects during or immediately after stimulation. Post-stimulation improvements were observed in the choice reaction time (increased percentage of correct answers; p = 0.01) and digit vigilance (reduced mean reaction time to correct answers; p = 0.02) attention tasks. Visuoperceptual task performance did not improve (all p-values > 0.05).

Attentional, but not visuoperceptual, improvements were observed following stimulation in LBD patients. Larger-scale, placebo-controlled trials are needed to confirm whether tDCS is a useful treatment option for attentional deficits in LBD.
