BACKGROUND: The 15-item version of the Geriatric Depression Scale (GDS-15) is widely employed to screen depression among elderly but little is known about the scale functioning in cognitively impaired individuals when compared to normal ones. The aim of the current study is to investigate Differential Item Functioning (DIF) across groups of older people that differ in terms of cognitive functioning applying Item Response Theory (IRT)-based analyses. METHODS: Data from an Italian multi-centric clinical-based study on cognitive impairment and dementia in old people were employed (N = 1903; Age: M = 77...

INTRODUCTION: Cerebral small vessel disease (CSVD) is associated with late-onset Alzheimer's disease (LOAD) and might contribute to the relationship between apolipoprotein E ε4 (APOEε4) and LOAD, in older people. However, it is unclear whether CSVD begins in middle age in individuals genetically predisposed to LOAD. METHODS: We assessed the relationship between radiological markers of CSVD, white matter hyperintensities and microbleeds, and genetic predisposition to LOAD in a cross-sectional analysis of cognitively normal subjects aged 40-59 years recruited from the PREVENT Dementia study...

Although Memorial Delirium Assessment Scale (MDAS) is a successful tool for delirium evaluation and monitoring, it is nevertheless important to determine whether cut-off scores vary according to the studied population. The main objective of this study is to evaluate the diagnostic sensitivity of the recently validated Spanish version of the MDAS. The secondary objective is to analyze possible diagnostic differences when used in a hospice or general hospital setting. METHODOLOGY: A prospective study was conducted with advanced cancer patients in two settings (hospice & general hospital)...

The aim of this study was to evaluate the incremental benefit of biomarkers for prediction of Alzheimer's disease dementia (ADD) in mild cognitive impairment (MCI) when added stepwise in the order of their collection in clinical routine. The model started with cognitive status characterized by the ADAS-13 score. Hippocampus volume (HV), cerebrospinal fluid (CSF) phospho-tau (pTau), and the FDG t-sum score in an AD-meta region-of-interest were compared as neurodegeneration markers. CSF-Aβ1-42 was used as amyloidosis marker...

BACKGROUND: The anti-aging protein, α-Klotho, may be involved in cognitive decline and has potential as a surrogate marker that reflects dementia. However, the role of α-Klotho in the brain has not been sufficiently investigated. OBJECTIVE: Here, we investigated the association between α-Klotho and cognitive decline that is associated with cerebral deep white matter lesions (DWMLs). METHODS: Two hundred-eighty participants (187 males and 93 females, mean age: 70...

Previous studies have suggested that pain in older people with dementia is often underestimated and undertreated in acute hospitals. Undermanaged pain negatively affects a person's recovery and prolongs hospital stays. However, the issues related to pain assessment and management by nurses for this group have not been fully understood. (1) To synthesize evidence about pain assessment and management for older people with dementia in hospital settings, and (2) to discuss implications for nurses and their practice...

BACKGROUND: Delirium is a challenging occurrence among people at end of life. It can be difficult to detect and treat because of its episodic nature. The Buffalo Delirium Scale (BDS) was designed to identify risk factors for hospice patients in the prodromal stage of delirium. OBJECTIVE: This study evaluated the psychometric properties of items assessing delirium risk factors related to cognitive problems, psychological distress, and sleep problems. METHODS: Hospice nursing staff assessed patients with the 11-item BDS over a 6-month period as part of standard weekly visits to monitor for emerging signs of delirium, for example, sleep patterns, cognition, and behavior...

Limited evidence exists regarding exercise interventions with individuals with dementia, which is often due to heterogeneity of methodology and outcomes being assessed. This led to the development and evaluation of a moderate-intensity home-based functional exercise program guided by theories from exercise science and the Strength-Based Approach. Data indicated excellent treatment adherence (99.04%) along with high levels of acceptability and feasibility in this sample (age 76.63 years (9.84); Mini Mental State Exam 18...

This paper reports on a process evaluation using mixed methods to assess a Dementia Care Coordination Program, which is distinctive in using the medical system, rather than direct outreach, to identify and refer families to supports provided by an Alzheimer's Association chapter via dedicated care consultants. One care consultant received referrals from individual physicians, while the other, employed by a health plan, received referrals from health plan case managers. Through key informant interviews, focus groups, and physician and caregiver surveys, we identified key issues, finding high rates of stakeholder satisfaction, but some practical issues around information sharing and data tracking...

BACKGROUND: The percentage of the older population is progressively increasing as are diseases associated with aging such as cognitive decline (CD) and dementia. Observational epidemiological studies suggest that diets rich in omega 3 polyunsaturated fatty acids (w3-PUFA) might reduce the risk of CD and dementia. The main objective was to assess whether there is sufficient scientific evidence about the relationship between w3-PUFA supplementation in patients aged 65 or older and cognitive performance...

Low subjective cognitive function (SCF), which is associated with APOE4 genotype, adversely impacts quality of life and has predicted clinical dementia. We examined whether physical activity during early adulthood or mid-to-late life is associated with late-life SCF. We followed 28,481 US male health professionals aged 40-75 years who reported their physical activity in 1986 and biennially thereafter. SCF was reported in 2008 and 2012. The SCF score was averaged for the 2008 and 2012 assessments and categorized as "good", "moderate", and "poor"...

The aim of this study was to determine whether frailty in older adults is associated with the risk of subsequent dementia. A total of 8,722 older adults from the English Longitudinal Study of Ageing were followed-up every two years until they reported a diagnosis of dementia, died, or were right censored. Frailty was defined using a frailty index comprised of 47 health deficits. To test if cognitive function influences the relationship between frailty and incident dementia, the analyses were repeated according to lower or upper three quartiles of baseline cognitive function...
