Neuroprotective effects of bilingualism in the prevention of cognitive impairment
https://doi.org/10.25789/YMJ.2025.92.26
Abstract
This literature review analyses current scientific research that focuses on the impact of bilingualism and multilingualism on human cognitive functions. The focus is on the impact of two or more language experiences on executive functions such as inhibitory control, cognitive flexibility and working memory. The article examines the concept of «bilingual advantage» and the factors that modulate its manifestation, as well as the role of bilingualism in the formation of cognitive reserve.
