Geriatric elderly older adult dementia alzheimer

As an intermediate state between normal aging and dementia, mild cognitive impairment (MCI), especially amnestic MCI (aMCI), is a key stage in the prevention and intervention of Alzheimer's disease (AD). Whether dancing could increase the hippocampal volume of seniors with aMCI remains debatable. The aim of this study was to investigate the influence of aerobic dance on hippocampal volume and cognition after 3 months of aerobic dance in older adults with aMCI. In this randomized controlled trial, 68 elderly people with aMCI were randomized to either the aerobic dance group or the control group using a 1:1 allocation ratio...

BACKGROUND: Several prospective Western studies have reported an inverse association of vegetable and fruit intake with dementia risk. However, there is limited epidemiologic evidence in Asians. This study investigated the association of intakes of vegetables, fruits, and their nutrients on the risk of incident dementia and its subtypes in a Japanese community. METHODS: A total of 1071 participants (452 men and 619 women) aged ≥60 years without dementia at baseline were prospectively followed up for 24 years...

The use of statins for primary prevention in older adults remains controversial. In this manuscript, we present a case of an 81-year-old woman with a history of HTN, HLD, Alzheimer's dementia and osteoporosis, who presented to a geriatrics clinic with profound muscle weakness accompanied by new functional deficits in the setting of taking double her prescribed dose of atorvastatin. She was admitted to the hospital where she was found to have rhabdomyolysis. Muscle biopsy and serologic work up revealed anti-HMG statin co-reductase myopathy as the cause of her symptoms...

BACKGROUND: Elderly population is rising significantly in Brazil. It may reach 25.5% of the population by 2060. Cognitive and functional declines may happen during pathological aging process. Low and medium-income countries tend to present higher dementia growth rate than high-income countries. The aim of this study was to assess whether socio-demographic and economic indicators are associated with cognitive performance in older adults with normal cognition and with mild cognitive impairment (MCI)...

BACKGROUND: With the rapid aging process, the number of elderly couple househol is increasing. Accordingly, when a patient with cognitive impairment occurs, the elderly spouse tends to take care of patient, and undergoes physical and psychological stress and changes in nutritional status due to the care, which can be a risk factor for cognitive decline.Therefore, this study aims to evaluate the spousal caregiver`s lifestyle, psychosocial factors and nutritional status related with cognition according to the burden of care for elderly couples...

BACKGROUND: One of the most marked problems in the use of screening instruments for the diagnosis of dementia or cognitive impairment in the elderly is the influence of educational level on the results of psychometric tests. The Montreal Cognitive Assessment (MoCA) questionnaire is one of the most widely used dementia screening instruments internationally and with greater proven validity. There is a version of this instrument called MoCA "Basic" which was developed to reduce education bias...

BACKGROUND: Neuropsychiatric symptoms (NPS) may represent early clinical manifestations of evolving brain diseases. Studies underpin the occurrence of NPS in the context of mild cognitive impairment (MCI) and prodromal Alzheimer's disease, where symptoms referred to as 'mild behavioural impairment' (MBI) have been shown to predict conversion to dementia and to hasten cognitive/functional decline. However, the association between NPS and cerebrovascular risk factors has been poorly investigated, despite the high prevalence of the latter among individuals with MCI...

BACKGROUND: Barthel Index (BI) is one of the most widely utilized tools for assessing functional independence in activities of daily living. Most existing BI studies used populations with specific diseases (e.g., Alzheimer's and stroke) to test prognostic factors of BI scores; however, the generalization of these findings was limited when the target populations varied. OBJECTIVES: The aim of the present study was to utilize electronic health records (EHRs) and data mining techniques to develop a generic procedure for identifying prognostic factors that influence BI score changes among community-dwelling elderly...

BACKGROUND: There is a growing concern regarding the increasing prevalence of common non-cancer chronic pain conditions (NCPCs) and their possible association with Alzheimer's disease and related dementias (ADRD). However, large population-based studies are limited, especially in Appalachian and other predominantly rural, underserved populations who suffer elevated prevalence of both NCPCs and known ADRD risk factors. OBJECTIVES: We investigated the relation of NCPC to risk of incident ADRD in older Appalachian Medicare beneficiaries and explored the potential mediating effects of mood and sleep disorders...

OBJECTIVE: The lack of disease-modifying pharmacological agents for dementia highlights the critical importance of prevention, but known modifiable factors (e.g., education, physical health and health behaviors, depression, and social isolation) do not fully represent potential intervention targets. Positive psychosocial factors predict cognitive aging outcomes above and beyond known risk factors and may also correspond to upstream determinants that open up new avenues for prevention and intervention, as well as for reducing racial/ethnic inequalities in dementia...

Older adults with mild cognitive impairment (MCI) have a high risk of developing Alzheimer's disease. Gait performance is a potential clinical marker for the progression of MCI into dementia. However, the relationship between gait and brain functional connectivity (FC) in older adults with MCI remains unclear. Forty-five subjects [MCI group, n = 23; healthy control (HC) group, n = 22] were recruited. Each subject performed a walking task (Task 01), counting backward-walking task (Task 02), naming animals-walking task (Task 03), and calculating-walking task (Task 04)...

BACKGROUND: Thailand has a rapidly aging population yet lacks evidence for effective and scalable evidence-based psychosocial interventions to support persons living with dementia and their family caregivers. In this study of a culturally adapted and evidence-based clinical program (Reducing Disabilities in Alzheimer's Disease [RDAD]), designed to reduce behavioral and psychological symptoms of dementia in older adults, the authors test the hypothesis that an implementation support strategy, Getting To Outcomes (GTO), would produce better implementation and clinical outcomes compared with usual implementation of RDAD in Thailand...

BACKGROUND: Scholars have noted that frailty easily leads to functional deterioration and proneness to complications. Little literature addresses the stages of frailty in middle-aged and older adults and the effects of frailty on overall health. AIMS: This study explores the effect of different stages of frailty on the prospective health (falls, bone fractures, disability, dementia, hospitalization, and death) of middle-aged and older adults. In addition, different frailty indicators were compared to determine their usefulness in predicting future adverse health outcomes...

INTRODUCTION: The Montreal Cognitive Assessment (MoCA) is a cognitive screening test widely used in clinical practice and suited for the detection of Mild Cognitive Impairment (MCI). The aims were to evaluate the psychometric properties of the Persian MoCA as a screening test for mild cognitive dysfunction in Iranian older adults and to assess its accuracy as a screening test for MCI and mild Alzheimer disease (AD). METHOD: One hundred twenty elderly with a mean age of 73...

BACKGROUND: It is crucial to evaluate the causes of morbidity and mortality in elderly patients with dementia, such as orthostatic hypotension (OH), which may affect their daily life activities, reduce the quality of life, and increase the caregiver burden. OBJECTIVE: We aimed to investigate the relationship between OH and the most common subtypes of dementia in detail. METHODS: A total of 268 older adults with dementia diagnosed with Alzheimer's disease (AD), dementia with Lewy bodies (DLB), vascular dementia (VaD), and behavioral variant frontotemporal dementia (bvFTD), and 539 older adults without dementia were included in this prospective study...

OBJECTIVES: While there is growing evidence of an association between depressive symptoms and postoperative delirium, the underlying pathophysiological mechanisms remain unknown. The goal of this study was to explore the association between depression and postoperative delirium in hip fracture patients, and to examine Alzheimer's disease (AD) pathology as a potential underlying mechanism linking depressive symptoms and delirium. METHODS: Patients 65 years old or older (N = 199) who were undergoing hip fracture repair and enrolled in the study "A Strategy to Reduce the Incidence of Postoperative Delirium in Elderly Patients" completed the 15-item Geriatric Depression Scale (GDS-15) preoperatively...

BACKGROUND/OBJECTIVES: It is unknown whether older adults at high risk of falls but without cognitive impairment have higher rates of subsequent cognitive impairment. DESIGN: This was an analysis of cross-sectional and longitudinal data from National Health and Aging Trends Study (NHATS). SETTING: NHATS, secondary analysis of data from 2011 to 2019. PARTICIPANTS: Community dwelling adults aged 65 and older without cognitive impairment...

BACKGROUND: The development of cognitive impairment and Fear of Falling (FoF) are strongly linked, but prevalence of FoF is not known in patients with different types of dementia. This study aims to evaluate and compare the prevalence and severity of FoF in patients' with dementia with Lewy bodies (DLB), Alzheimer disease (AD), and non-dementia. METHODS: 46 participants with DLB, 86 participants with AD and participants without dementia (controls), underwent Comprehensive Geriatric Assessment (CGA)...

BACKGROUND AND OBJECTIVE: Dementia is one of the most frequent diseases in the elderly, being its prevalence of up to 64% in institutionalized people. In this population, in addition to antidementia drugs, it is common to prescribe drugs with anticholinergic/sedative burden that, due to their adverse effects, could worsen their functionality and cognitive status. The objective is to estimate the prevalence of the use of drugs with anticholinergic/ sedative burden in institutionalized older adults with dementia and to assess the associated factors...

BACKGROUND: Subsyndromal symptomatic depression (SSD) is prevalent in older adults. However, it remains unclear whether there are effects of SSD on brain aging outcomes (cognition and brain structures), especially in the presence of Alzheimer's Disease (AD) pathology. METHODS: A total of 1,188 adults without dementia were recruited from the Alzheimer's Disease Neuroimaging Initiative (ADNI) database. Participants with SSD were measured using the 15-item Geriatric Depression Scale (GDS-15)...
