Abstract This report discusses the public health impact of Alzheimer's disease (AD), including incidence and prevalence, mortality rates, costs of care and the overall effect on caregivers and ...society. It also examines the challenges encountered by health care providers when disclosing an AD diagnosis to patients and caregivers. An estimated 5.3 million Americans have AD; 5.1 million are age ≥65 years, and approximately 200,000 are age <65 years and have younger onset AD. By mid-century, the number of people living with AD in the United States is projected to grow by nearly 10 million, fueled in large part by the aging baby boom generation. Today, someone in the country develops AD every 67 seconds. By 2050, one new case of AD is expected to develop every 33 seconds, resulting in nearly 1 million new cases per year, and the estimated prevalence is expected to range from 11 million to 16 million. In 2013, official death certificates recorded 84,767 deaths from AD, making AD the sixth leading cause of death in the United States and the fifth leading cause of death in Americans age ≥65 years. Between 2000 and 2013, deaths resulting from heart disease, stroke and prostate cancer decreased 14%, 23% and 11%, respectively, whereas deaths from AD increased 71%. The actual number of deaths to which AD contributes (or deaths with AD) is likely much larger than the number of deaths from AD recorded on death certificates. In 2015, an estimated 700,000 Americans age ≥65 years will die with AD, and many of them will die from complications caused by AD. In 2014, more than 15 million family members and other unpaid caregivers provided an estimated 17.9 billion hours of care to people with AD and other dementias, a contribution valued at more than $217 billion. Average per-person Medicare payments for services to beneficiaries age ≥65 years with AD and other dementias are more than two and a half times as great as payments for all beneficiaries without these conditions, and Medicaid payments are 19 times as great. Total payments in 2015 for health care, long-term care and hospice services for people age ≥65 years with dementia are expected to be $226 billion. Among people with a diagnosis of AD or another dementia, fewer than half report having been told of the diagnosis by their health care provider. Though the benefits of a prompt, clear and accurate disclosure of an AD diagnosis are recognized by the medical profession, improvements to the disclosure process are needed. These improvements may require stronger support systems for health care providers and their patients.

The phenomenon of the increasing number of ageing people in the world is arguably the most significant economic, health and social challenge that we face today. Additionally, one of the major ...epidemiologic trends of current times is the increase in chronic and degenerative diseases. This paper tries to deliver a more up to date overview of chronic diseases and other limitations associated with old age and provide a more detailed outlook on the research that has gone into this field.
First, challenges for seniors, including chronic diseases and other limitations associated with old age, are specified. Second, a review of seniors' needs and concerns is performed. Finally, solutions that can improve seniors' quality of life are discussed. Publications obtained from the following databases are used in this scoping review: Web of Science, PubMed, and Science Direct. Four independent reviewers screened the identified records and selected relevant publications published from 2010 to 2017. A total of 1916 publications were selected. In all, 52 papers were selected based on abstract content. For further processing, 21 full papers were screened."
The results indicate disabilities as a major problem associated with seniors' activities of daily living dependence. We founded seven categories of different conditions - psychological problems, difficulties in mobility, poor cognitive function, falls and incidents, wounds and injuries, undernutrition, and communication problems. In order to minimize ageing consequences, some areas require more attention, such as education and training; technological tools; government support and welfare systems; early diagnosis of undernutrition, cognitive impairment, and other diseases; communication solutions; mobility solutions; and social contributions.
This scoping review supports the view on chronic diseases in old age as a complex issue. To prevent the consequences of chronic diseases and other limitations associated with old age related problems demands multicomponent interventions. Early recognition of problems leading to disability and activities of daily living (ADL) dependence should be one of essential components of such interventions.

Few studies have examined the relationship between non-cognitive factors and activities of daily living (ADL) according to Alzheimer's disease (AD) stage.
We aimed to identify the differences in ...non-cognitive factors according to AD stages and their involvement in basic and instrumental ADL performance by using intrinsic capacity (IC) in groups with cognition ranging from normal to moderate or severe AD.
We enrolled 6397 patients aged≥65 years who visited our memory clinic. Non-cognitive IC was assessed using the locomotion, sensory, vitality, and psychological domains. Multiple logistic regression was performed to identify how non-cognitive IC declines over the AD course and examine the correlation between non-cognitive IC and basic and instrumental ADL performance.
Non-cognitive IC declined from the initial AD stage and was significantly correlated with both basic and instrumental ADL performance from the aMCI stage through all AD stages. In particular, the relationship between IC and basic ADL was stronger in mild and moderate to severe AD than in the aMCI stage. On the other hand, the relationship between IC and instrumental ADL was stronger in aMCI than in later AD stages.
The results show non-cognitive factors, which decline from the aMCI stage, are correlated with ADL performance from the aMCI stage to almost all AD stages. Considering that the relationship strength varied by ADL type and AD stage, an approach tailored to ADL type and AD stage targeting multiple risk factors is likely needed for effectively preventing ADL performance declines.
Background: Frailty has been shown to be associated with disability in the previous studies. However, it is not clear how consistently or to how much degree frailty is actually associated with the ...future disability risks.
Methods: A systematic review of the literature was conducted using Embase, MEDLINE, CINAHL, PsycINFO, and the Cochrane Library for any prospective studies published from 2010 to September 2015 examining associations between baseline frailty status and subsequent risk of developing or worsening disabilities among community-dwelling older people. A meta-analysis was performed to synthesize pooled estimates.
Results: Of 7012 studies identified through the systematic review, 20 studies were included in the meta-analysis. Twelve studies examined activities of daily living (ADL) disability risks, two studies examined instrumental activities of daily living (IADL) disability risks, and six studies examined both ADL and IADL disability risks. Overall, frail older people were more likely to develop or worsen disabilities in ADL (12 studies, pooled OR = 2.76, 95% CI = 2.23-3.44, p < 0.00001; 5 studies, pooled HR = 2.23, 95% CI = 1.42-3.49, p < 0.00001) and IADL (6 studies, pooled OR = 3.62, 95% CI = 2.32-5.64, p < 0.00001; 2 studies, pooled HR = 4.24, 95% CI = 0.85-21.28, p = 0.08). Prefrailty was also associated with incident or worsening disability risks to a lesser degree in most pooled analyses. High heterogeneity observed among 12 studies with OR of ADL disability risks for frailty was explored using subgroup analyses, which suggested methodological quality and mean age of the cohort were the possible causes.
Conclusion: This systematic review meta-analysis quantitatively showed that frail older people are at higher risks of disabilities. These results are important for all related parties given population aging worldwide. Interventions for frailty are important to prevent disability and preserve physical functions, autonomy, and quality of life.
Implications for Rehabilitation
Although frailty has been shown to be associated with disability and considered as a precursor of disability, it is not clear how consistently or to how much degree frailty is actually associated with the future disability risks.
This systematic review and meta-analysis quantitatively shows frailty is a significant predictor of incident and worsening ADL and IADL disabilities.
It is a pressing priority to develop interventions for frailty to prevent disability and preserve older people's physical functions, autonomy, and quality of life.

Significant innovations have been introduced in recent years in the application of information and communication technologies (ICTs) to support healthcare for patients with dementia.
In the present ...systematic review, our goal is to keep track of ICT concepts and approaches to support the range of activities of daily living for people with dementia and to provide a snapshot of the effect that technology is having on patients' self-reliance.
We reviewed the literature and identified systematic reviews of cohort studies and other authoritative reports. Our selection criteria included: (1) activities of daily living, (2) ICT, and (3) dementia.
We identified 56 studies published between 2000 and 2015, of which 26 met inclusion criteria. The present systematic review revealed many ICT systems that could purportedly support the range of activities of daily living for patients with dementia. The results showed five research bodies: 1) technologies used by patients with dementia, 2) technologies used by caregivers, 3) monitoring systems, 4) ambient assistive living with ICTs, and 5) tracking and wayfinding.
There is a potential for ICTs to support dementia care at home and to improve quality of life for caregivers, reducing healthcare costs and premature institutional care for these patients.
Objectives
As the psychosocial competence, personal mastery helps individuals to cope with stressful life events, and this study aims to examine impacts of declines in personal mastery on healthy ...aging among community-dwelling middle-aged and older adults using a nationally representative cohort.
Methods
Data from 648 study participants in the Social Environment and Biomarkers of Aging Study (SEBAS) were retrieved for analysis. All participants were divided into four groups based on their baseline and changes of personal mastery (measured by the Pearlin mastery score) during the 6-year follow-up. Multivariate logistic regression models were adopted to examine associations between declines in personal mastery and indicators for healthy aging (declines in self-perceived mobility, physical function (activities of daily living (ADLs) and instrumental activities of daily living (IADLs)), cognitive function and depressive symptoms).
Results
After adjustments for demographics and comorbidities, those with declines in personal mastery were associated with greater risks of declines in self-perceived mobility (adjusted odds ratio (aOR) 1.50 95% confidence interval 1.01–2.22, p < 0.05). Although the point estimate in the unadjusted models indicated similar associations between declines in personal mastery and declines in ADLs, IADLs, cognitive function or depressive symptoms, these outcomes did not reach statistical significance in the adjusted model.
Conclusions
Declines in personal mastery were negatively associated with indicators related to healthy aging (particularly locomotion) in a 6-year follow-up. Further investigations are needed to explore the effects of preventing declines in personal mastery in promoting healthy aging over time.

IMPORTANCE: Enhanced understanding of factors associated with symptomatic and functional recovery is instrumental to designing personalized treatment plans for people with schizophrenia. To date, ...this is the first study using network analysis to investigate the associations among cognitive, psychopathologic, and psychosocial variables in a large sample of community-dwelling individuals with schizophrenia. OBJECTIVE: To assess the interplay among psychopathologic variables, cognitive dysfunctions, functional capacity, personal resources, perceived stigma, and real-life functioning in individuals with schizophrenia, using a data-driven approach. DESIGN, SETTING, AND PARTICIPANTS: This multicenter, cross-sectional study involved 26 university psychiatric clinics and/or mental health departments. A total of 921 community-dwelling individuals with a DSM-IV diagnosis of schizophrenia who were stabilized on antipsychotic treatment were recruited from those consecutively presenting to the outpatient units of the sites between March 1, 2012, and September 30, 2013. Statistical analysis was conducted between July 1 and September 30, 2017. MAIN OUTCOMES AND MEASURES: Measures covered psychopathologic variables, neurocognition, social cognition, functional capacity, real-life functioning, resilience, perceived stigma, incentives, and service engagement. RESULTS: Of 740 patients (221 women and 519 men; mean SD age, 40.0 10.9 years) with complete data on the 27 study measures, 163 (22.0%) were remitted (with a score of mild or better on 8 core symptoms). The network analysis showed that functional capacity and everyday life skills were the most central and highly interconnected nodes in the network. Psychopathologic variables split in 2 domains, with positive symptoms being one of the most peripheral and least connected nodes. Functional capacity bridged cognition with everyday life skills; the everyday life skills node was connected to disorganization and expressive deficits. Interpersonal relationships and work skills were connected to avolition; the interpersonal relationships node was also linked to social competence, and the work skills node was linked to social incentives and engagement with mental health services. A case-dropping bootstrap procedure showed centrality indices correlations of 0.75 or greater between the original and randomly defined samples up to 481 of 740 case-dropping (65.0%). No difference in the network structure was found between men and women. CONCLUSIONS AND RELEVANCE: The high centrality of functional capacity and everyday life skills in the network suggests that improving the ability to perform tasks relevant to everyday life is critical for any therapeutic intervention in schizophrenia. The pattern of network node connections supports the implementation of personalized interventions.
Background Slow walk (gait) speed predicts functional decline, institutionalization, and mortality risks in the geriatric population. A gait speed evidence base for dialysis patient outcomes is ...needed. Study Design Prospective cohort study. Setting & Participants 752 prevalent hemodialysis (HD) patients aged 20 to 92 years evaluated in 2009 to 2012 in 7 Atlanta and 7 San Francisco clinics in a US Renal Data System special study. Predictor Usual walk speed in meters per second, categorized as ≥0.6 m/s (baseline n = 575), <0.6 m/s (baseline n = 94), and unable to perform walk test (baseline n = 83). Outcomes Survival; hospitalization; activities of daily living (ADL) difficulty; 36-Item Short Form Health Survey (SF-36) Physical Function score. Measurements Cox proportional hazards models investigated gait speed and mortality over a median follow-up of 703 days. Multivariable logistic or linear regression models estimated associations of baseline gait speed with hospitalization, need for ADL assistance, and SF-36 Physical Function score after 12 months. Results Participants who walked ≥0.6 m/s had 53 (9%) deaths, those who walked <0.6 m/s had 19 (20%) deaths, and those unable to walk had 37 (44%) deaths. Adjusted mortality hazard ratios were 2.17 (95% CI, 1.19-3.98) for participants who walked <0.6 m/s and 6.93 (95% CI, 4.01-11.96) for those unable to walk, compared with participants walking ≥0.6 m/s. After 12 months, compared with baseline walk speed ≥ 1.0 m/s (n = 169 participants), baseline walk speed of 0.6 to <0.8 m/s (n = 116) was associated with increased odds of hospitalization (OR, 2.04; 95% CI, 1.19-3.49) and ADL difficulty (OR, 3.88; 95% CI, 1.46-10.33) and a −8.20 (95% CI, −13.57 to −2.82) estimated change in SF-36 Physical Function score. Limitations Cohort not highly representative of overall US in-center HD population. Conclusions Because walking challenges the heart, lungs, and circulatory, nervous, and musculoskeletal systems, gait speed provides an informative marker of health status. The association of gait speed with HD patients’ risk for functional decline warrants continued study.
The extension of the life span has led to an increase in the number of older people and an increase in the prevalence of disability in people over 60 years of age. The aim of this study was to assess ...the prevalence of ADL and IADL disability and to analyze its determinants among people aged 60 and older living in southeastern Poland.
This cross-sectional study was carried out among a randomly selected, representative population of people aged 60 and older living in southeastern Poland. Disability was assessed using the Katz Index of Independence in Basic Activities of Daily Living and Instrumental Activities of Daily Living. Logistic regression models were used to identify the factors related to ADLs and IADLs. For the variables that were included in the above models, their clustered influence on the increase in the odds ratio for the occurrence of an ADL or IADL limitation was also examined.
The research results show that 35.75% of the participants reported at least one problem with IADLs. At least one problem with ADLs was reported by 17.13% of the participants. The most significant modifiable factors influencing the occurrence of disability were the presence of barriers in the participant's environment, poor relations with relatives, a lack of social contacts, multimorbidity and pain. A multiple increase in the odds ratio of disability was found with the presence of pairs of analyzed factors. The highest odds ratio of at least one ADL limitation was observed for the combination of barriers in the participant's environment with multimorbidity (OR 74.07). With regard to IADL disability, the highest odds ratio was observed for the combination of pain on the VAS scale ≥3 points with older age (OR 19.47).
The study showed a high prevalence of ADL and IADL disability in older people living in southeastern Poland. It also indicated the extent to which modifiable factors influenced the occurrence of disability and the extent to which the risk of disability increased with the presence of pairs of factors, especially those that included environmental barriers in the participant's environment.
We performed a systematic review to assess the psychometric properties of extended Activities of Daily Living (eADL) scales.
Articles assessing eADL scales' properties were retrieved by searching ...multidisciplinary databases, and reference screening. Data on the following properties were extracted: validity, reliability, responsiveness, and internal consistency. The COSMIN (Consensus-based Standards for the selection of health status Measurement Instruments) risk of bias checklists are used to assess the quality of included articles. All aspects were performed by two independent researchers.
Of 245 titles, 26 articles were eligible, comprising 15 different eADL scales. The Lawton scale had the most papers describing properties, while the Performance-based Instrumental Activities of Daily Living received the highest COSMIN rating. Properties most often assessed were convergent validity and reliability, no articles assessed all COSMIN properties. The COSMIN assessment rated 43% of the properties as 'positive', 31% 'doubtful' and 26% 'inadequate'. Only Lawton was assessed in more than one paper, available data suggest that this scale has excellent reliability, construct validity, internal consistency, and medium criterion validity.
Despite their common use, there are limited data on the properties of eADL scales. Where data are available there are potential methodological issues in the studies.
Implications for Rehabilitation
The functional abilities of older adults are most commonly measured using extended activities of daily living scales (eADL).
There are many eADL scales available to clinicians and no guidance on a preferred tool.
Despite the frequent use of eADL scales in research and practice, there is limited published literature on their psychometric properties (for example validity, reliability and responsiveness).
The Lawton Scale has the most supporting evidence and its properties are generally acceptable, more research is needed on other eADL scales.
