Cognitive Frailty: An Update

2021

This review article provides an update of the empirical research on cognitive fragility conducted in the last four years. The studies retrieved were classified in four different categories. The first category includes articles relating cognitive frailty to cognitive reserve and which continue to highlight the importance of educational level. The second category includes recent research on cognitive fragility biomarkers, involving neuroimaging, metabolism and, in a novel way, microbiota. The third category includes research on how cognitive frailty is related to motor development and physical functioning, exploring e.g. the use of technology to study motor markers of cognitive frailty.

Microscopical and Mycological Investigations on Wood of Pendunculate Oak (Quercus robur L) Relative to the Occurrence of Oak Decline

1996

Summary Microscopical studies exhibited great differences between healthy and damaged pendunculate oak trees (Quercus robur L.) relative to the state of sapwood vessels and the degree of fungal infection. In the sapwood of damaged trees deposits, discolorations and early tylosis formations were found which frequently occurred in combination with fungal infections. These results lead to the assumption that the defence reaction of the trees probably induced by fungal infection changes the structure of the tree vessels to such an extent that their water transfer function is disturbed. Some fungal genera playing an important role in the discussion of the causes of oak decline could be isolated.…

Potential Benefits and Limitations of Enriched Environments and Cognitive Activity on Age-Related Behavioural Decline

2011

The main aim of this chapter is to review preclinical studies that have evaluated interventions which may aid in preventing or delaying age-related behavioural decline. Animal models of Environmental Enrichment (EE) are useful for evaluating the influence of cognitive, physical and social stimulation in mitigating cognitive decline at different ages. The EE paradigm has been proposed as a non-invasive treatment for alleviating age-related memory impairment and neurodegenerative diseases. While in this complex environment, rodents can be stimulated at different levels (physical, social, cognitive and sensorial), although a synergism between all these components is likely to play an important…

Fluência verbal fonêmica e semntica: dados normativos de idosos Brasileiros

2015

This study aims to investigate the influence of sociodemographic characteristics on the performance of older people on two tasks of verbal fluency and provide normative data for a Brazilian population of healthy elderly individuals with different educational levels. The initial sample included 521 individuals aged from 60 years, participating in the Program Family Health Strategy. Participants who had scores suggestive of cognitive decline on the Mini-Mental State Examination, depressive symptoms in Geriatric Depression Scale and self-reported neurological or psychiatric disorders were excluded. The final sample consisted of 218 participants in phonemic verbal fluency task (letters F, A and…

Nutritional screening of patients at a memory clinic--association between patients' and their relatives' self-reports.

2015

Aims and objectives To compare individual reports by patients and relatives (proxy) of the Nutritional Form For the Elderly and relate the Nutritional Form For the Elderly scores to Mini Mental Status Examination scores, weight loss, Body Mass Index, five-point Clock Drawing Test and background variables. Background Undernutrition or risk of undernutrition is a significant problem among people with dementia. A poor nutritional state increases the risk of infections, delayed convalescence after acute illness and reduced quality of life. Design A cross-sectional study. Method Application of the Nutritional Form For the Elderly in addition to clinical nutrition parameters and cognitive tests i…

Mild cognitive decline. A position statement of the Cognitive Decline Group of the European Innovation Partnership for Active and Healthy Ageing (EIP…

2016

Introduction: Mild cognitive impairment (MCI) is a term used to describe a level of decline in cognition which is seen as an intermediate stage between normal ageing and dementia, and which many consider to be a prodromal stage of neurodegeneration that may become dementia. That is, it is perceived as a high risk level of cognitive change. The increasing burden of dementia in our society, but also our increasing understanding of its risk factors and potential interventions, require diligent management of MCI in order to find strategies that produce effective prevention of dementia. Aim: To update knowledge regarding mild cognitive impairment, and to bring together and appraise evidence abou…

Mobility Limitation and Changes in Personal Goals Among Older Women.

2016

Objectives. Several theoretical viewpoints suggest that older adults need to modify their personal goals in the face of functional decline. The aim of this study was to investigate longitudinally the association of mobility limitation with changes in personal goals among older women. Method. Eight-year follow-up of 205 women aged 66–78 years at baseline. Results. Health-related goals were the most common at both measurements. Goals related to independent living almost doubled and goals related to exercise and to cultural activities substantially decreased during the follow-up. Higher age decreased the likelihood for engaging in new goals related to cultural activities and disengaging from g…

Use of walking modifications, perceived walking difficulty and changes in outdoor mobility among community-dwelling older people during COVID-19 rest…

2021

Abstract Background Outdoor mobility enables participation in essential out-of-home activities in old age. Aim To compare changes in different aspects of outdoor mobility during COVID-19 restrictions versus two years before according to self-reported walking. Methods Community-dwelling participants of AGNES study (2017–2018, initial age 75–85) responded to AGNES-COVID-19 postal survey in spring 2020 (N = 809). Life-space mobility, autonomy in participation outdoors, and self-reported physical activity were assessed at both time points and differences according to self-reported walking modifications and difficulty vs. intact walking at baseline were analyzed. Results Life-space mobility and …
