Lifespan Changes of the human brain in Alzheimer's disease
2018
[EN] Brain imaging studies have shown that slow and progressive cerebral atrophy characterized the development of Alzheimer's Disease (AD). Despite a large number of studies dedicated to AD, key questions about the lifespan evolution of AD biomarkers remain open. When does the AD model diverge from the normal aging model? What is the lifespan trajectory of imaging biomarkers for AD? How do the trajectories of biomarkers in AD differ from normal aging? To answer these questions, we proposed an innovative way by inferring brain structure model across the entire lifespan using a massive number of MRI (N = 4329). We compared the normal model based on 2944 control subjects with the pathological …
Influencia del aceite de coco en enfermos de alzhéimer a nivel cognitivo.
2017
Resumen Introducción: la enfermedad de Alzheimer es a día de hoy la demencia neurodegenerativa con mayor prevalencia en el primer mundo. Este hecho, unido a la falta de tratamiento farmacológico que cure la enfermedad, hace que se estudien nuevas estrategias terapéuticas no farmacológicas como es la administración de nutrientes. En este sentido, destaca la posible influencia del aceite de coco como fuente energética alternativa, capaz de frenar la muerte neuronal que se produce de modo progresivo en esta enfermedad. Objetivos: valorar el impacto del aceite de coco a nivel cognitivo en pacientes de alzhéimer, y concretamente en las áreas de orientación, lenguaje-construcción, fijación, cálcu…
Designing ICTs for Users with Mild Cognitive Impairment: A Usability Study
2020
Background: Research has supported the cost-effectiveness of cognitive training tools enhanced by information and communication technologies (ICT) in several populations, including individuals with mild cognitive impairment (MCI) and age-related cognitive decline. The implementation of ICTs in this population, however, is sometimes challenging to their cognitive and age characteristics. Ultimately, this might compromise the effectiveness of ICT-enhanced therapies in this population. The aim of this study is to test the usability and acceptability of a European project prototype for elderly care, in an attempt to explore the ICT design needs of users with MCI. Methods: Participants were 28 i…
Associative and implicit memory performance as a function of cognitive reserve in elderly adults with and without mild cognitive impairment
2016
AbstractThis study aims to analyze implicit and explicit memory performance as a function of cognitive reserve (CR) in a healthy control group (N = 39) and a mild cognitive impairment (MCI) group (N = 37). Both groups were subdivided into high and low cognitive reserve, and were asked to complete an explicit and implicit associative recognition tasks. The results showed that the control group was able to learn both tasks (η2 = .19, p < .0001), and the high CR group fared better (η2 = .06, p < .05). The MCI sample, conversely, was unable to learn the implicit relationship, and showed very little learning on the explicit association task. Participants diagnosed with MCI showed little pl…
Aproximación a la Clasificación del Deterioro Cognitivo Leve (DCL) en una muestra de personas mayores institucionalizadas
2011
Actualmente, se considera que el envejecimiento puede clasificarse en tres tipos, el normal, el patológico, donde se encontraría el deterioro cognitivo leve (DCL) y finalmente, el envejecimiento óptimo. A partir de los resultados obtenidos en diferentes pruebas de evaluación neuropsicológica, se plantea como objetivo, establecer grupos diagnósticos de DCL, para describirlos y compararlos. La aplicación de las pruebas se realiza a 20 personas de entre 65 y 94 años, residentes en un centro para mayores de Valencia, España. Los resultados mostraron que, el grupo más frecuente fue el de DCL multidominio no amnésico, y que el menos frecuente el DCL amnésico. Pruebas como el WMS dígitos, la prueb…
Psychological changes through the lifespan: Ageing and psychosocial-related variables
2022
This series of papers examines aspects of aging cognition in both healthy older adults and those diagnosed with dementias, and although few in number, gives an important overview of some of the key issues in examining the relationships between aging and psychosocial variables, including social cognition. The special issue includes five papers which cover: goal related decision making (Ito et al.); trust in cooperative behavior (Telga and Lupianez); impact of anxiety on self-perceived cognitive difficulties (Spalding et al.); factors associated with depression in Wuhan, China (Liu et al.); and neurophysiological functional connectivity related to apathy in people living with dementia (Altunk…
