Worldwide, people engage insufficiently in physical activity, particularly subjects aged 80 years and over. For optimal life-style campaigns, knowledge of motivators and barriers for physical activity is mandatory. Given their specific needs, it is conceivable that these would be different for the oldest old compared to younger subjects. Pubmed, Web of(More)
OBJECTIVES Assessment of advanced activities of daily living (a-ADL) can be of interest in establishing the diagnosis of Alzheimer's disease (AD) in an earlier stage, since these activities demand high cognitive functioning and are more responsive to subtle changes. In this study we tested a new a-ADL tool, developed according to the International(More)
BACKGROUND Low grip strength is recognized as one of the characteristics of frailty, as are systemic inflammation and the sensation of fatigue. Contrary to maximal grip strength, the physical resistance of the muscles to fatigue is not often included in the clinical evaluation of elderly patients. The aim of this study was to investigate if the grip(More)
This study evaluated whether reaction times (RT) and performance variability are potential markers for the early detection of Alzheimer's disease (AD). Cognitively healthy elderly (n = 218), persons with amnestic MCI (a-MCI) (n = 29) and patients with AD (n = 50) were examined with RT tasks with increasing complexity, subdividing RT into a decision and a(More)
BACKGROUND It is generally accepted that Alzheimer's disease (AD) is mainly characterized by memory disorders. Although recent studies also point to an important role of attention deficits early in the disease, this notion has not yet emerged in clinical practice. Our aim was to assess whether attention, quantified by reaction times, can discriminate(More)
BACKGROUND AND PURPOSE Although physical activity (PA) is an important tool to counter osteoporosis, too few older patients with osteoporosis (OPWO) engage in PA. Little is known about specific motivators for and barriers to PA in OPWO, hindering the development of targeted PA promotion campaigns for these persons. Therefore, the main objective of this(More)
To date, the major dilemma concerning frailty is the lack of a standardized language regarding its operationalization. Considering the demographic challenge that the world is facing, standardization of frailty identification is indeed the first step in tackling the burdensome consequences of frailty. To demonstrate this diversity in frailty assessment, the(More)
BACKGROUND Mild cognitive impairment (MCI) is characterized by subjective and objective memory impairments in the absence of manifest functional decline. Mild changes in activities of daily living (ADL) can be present and probably predict conversion to dementia. A new advanced (a)-ADL tool was developed, evaluating high-level activities and, taking each(More)
Multiple causes contribute to the prolonged reaction-times (RT) observed in elderly persons. The involvement of antagonist muscle co-activation remains unclear. Here the Mm. Biceps and Triceps Brachii activation in 64 apparently healthy elderly (80 ± 6 years) and 60 young (26 ± 3 years) subjects were studied during a simple RT-test (moving a finger using(More)
BACKGROUND AND AIMS Performance variability of reaction time is regarded as an important parameter for cognitive functioning with aging. We investigated three types of variability, diversity (or variability between persons), dispersion (variability across trials within one task) and inconsistency (variability across testing occasions), while distinguishing(More)
