Maintaining Cognitive Functioning in Healthy Seniors with a Technology-Based Foreign Language Program: A Pilot Feasibility Study

Autor: Anne-Sophie Rigaud, Victoria Cristancho, Leila Djabelkhir, Judith Benovici, Ya-Huei Wu, Maribel Pino, Souad Damnée, Caitlin Ware

Publikováno v: Frontiers in Aging Neuroscience

Researchers have hypothesized that learning a foreign language could be beneficial for seniors, as language learning requires the use of extensive neural networks. We developed and qualitatively evaluated an English training program for older French

Characterizing age from handwriting (HW) has important applications, as it is key to distinguishing normal HW evolution with age from abnormal HW change, potentially triggered by neurodegenerative decline. We propose, in this work, an original approa
