Background and Objectives: Sitting less can reduce older adults' risk of ill health and disability. Effective sedentary behavior interventions require greater understanding of what older adults do when sitting (and not sitting), and why. This study compares the types, context, and role of sitting activities in the daily lives of older men and women who sit more or less than average. Research Design and Methods: Semistructured interviews with 44 older men and women of different ages, socioeconomic status, and objectively measured sedentary behavior were analyzed using social practice theory to explore the multifactorial, inter-relational influences on their sedentary behavior...

WHAT IS KNOWN AND OBJECTIVE: Anticholinergic drugs are associated with risks of falls, confusion and cognitive dysfunction. However, the effect of anticholinergic drug use on rehabilitation outcomes after a stroke is poorly documented. We therefore aimed to establish whether the anticholinergic load was associated with functional recovery among geriatric patients convalescing after stroke. METHOD: Consecutive geriatric stroke patients admitted and discharged from a convalescence rehabilitation ward between 2010 and 2016 were included in this retrospective cohort study...

Sara J Margolin
Background/Study context: Previous research has demonstrated that negated text is universally difficult to understand, and while readers are aware of the difficulty, they are not always able to direct this awareness to improve their comprehension of negation. The present research aimed to determine whether this holds true for older adults, even while maintaining good cognitive function through reading activity. METHODS: The study used an online paradigm, where young (age range 19-24) and older (age range 60-87) adults read passages, rated their comprehension, and answered questions about what they read...

Working memory is composed of different processes and encompasses not only the temporary storage of information but also its manipulation in order to perform complex cognitive activities. During childhood, one of these manipulation processes, namely active controlled retrieval, improves significantly between the age of 6 to 10, suggesting that the neuronal network supporting this function undergoes substantial maturational changes. The present study examined the neural activity of 14 healthy children and 14 adults while performing an active controlled retrieval task...

AIMS: Recent recommendations of US and UK governmental and academic agencies suggest that up to 35% of dementia cases are preventable. We aimed to appraise general practitioners' (GPs) awareness of risk and protective factors associated with dementia and their intentions to act within the context of the Health Beliefs Model. METHODS: We canvassed degree of dementia awareness, using the modified Lifestyle for Brain Health (LIBRA) scale among a convenience sample of local GPs...

The goal of this research was to examine the linkage between personal resources, intrinsic motivation, and participation in everyday activities. It was hypothesized the reductions in resources in later life will be associated with reduced motivation to engage in cognitively demanding activities, leading to reduction in participation in such activities in everyday life. To test this, we utilized data from the 2010 and 2012 waves of the Health and Retirement Survey. We used structural equation modeling to construct latent factors associated with health resources, cognitive resources, and intrinsic motivation...

Background: Although increased cognitive activity (CA), both current and past, is known to be associated with a decreased occurrence of Alzheimer's disease (AD) dementia in older adults, the exact neural mechanisms underlying the association between CA during different stages of life and human dementia remain unclear. Therefore, we investigated whether CA during different life stages is associated with cerebral amyloid-beta (Aβ) pathology and AD-related neurodegeneration in non-demented older adults. Methods: Cross-sectional analyses of data collected between April 2014 and March 2016 from the Korean Brain Aging Study for Early Diagnosis and Prediction of Alzheimer's Disease (KBASE), an ongoing prospective cohort...

OBJECTIVE: Age differences have been noted in the discrepancies between crystallized and fluid ability (Gc-Gf). Larger Gc-Gf discrepancies have also been shown to be associated with Alzheimer's disease biomarkers and clinical severity. However, little is known regarding the relationship between Gc-Gf discrepancies in normal aging and functional outcomes. The aim of the present study was to examine this. METHOD: Data from 104 adults (Mage  = 71.70 years, SD = 9...

INTRODUCTION: Mental fatigue is a psychobiological state caused by prolonged periods of demanding cognitive activity that has negative implications on many aspects in daily life. Caffeine and carbohydrate ingestion have been shown to be able to reduce these negative effects of mental fatigue. Intake of these substances might however be less desirable in some situations (e.g., restricted caloric intake, Ramadan). Rinsing caffeine or glucose within the mouth has already been shown to improve exercise performance...

The basal levels of extracellular Zn2+ are in the range of low nanomolar concentrations and less attention has been paid to Zn2+ , compared to Ca2+ , for synaptic activity. However, extracellular Zn2+ is necessary for synaptic activity. The basal levels of extracellular zinc are age-dependently increased in the rat hippocampus, implying that the basal levels of extracellular Zn2+ are also increased age-dependently and that extracellular Zn2+ dynamics are linked with age-related cognitive function and dysfunction...

INTRODUCTION: There are few intervention studies that demonstrated linking social participation to lower risk of cognitive decline. We examined prospectively the protective effect of a community intervention program promoting social participation on the incidence of cognitive disability. METHODS: The baseline was established in a survey of community-dwelling older people aged 65 years old or more in July 2006 (2793 respondents, response rate 48.5%). The setting was Taketoyo town in Japan, where municipal authorities launched an intervention that was based on the establishment of community-based centers called "salons," where the town's senior residents could congregate and participate in social activities, ranging from arts and crafts, games, and interactive activities with preschool children...

We evaluated the role of cognitive and brain reserve markers in modifying the risk of postoperative delirium associated with a pathophysiologic marker. The Successful Aging after Elective Surgery study (SAGES) enrolled 556 adults age ≥70 years without dementia scheduled for major surgery. Patients were assessed preoperatively and daily during hospitalization for delirium. We used C-reactive protein (CRP) as a pathophysiologic marker of inflammation, previously associated with delirium. Markers of reserve included vocabulary knowledge, education, cognitive activities, occupation type and complexity, head circumference, intracranial volume, and leisure activities...
