The Bilingual Advantage

Cognitive neuroscientist Ellen Bialystok has uncovered that speaking two or more languages increases aging adults' cognitive function and helps people with Alzheimer's disease deal with the symptoms better.  Explaining the science behind it, Bialystok described how bilinguals' brains constantly have to ignore one language or the other, training the brain to concentrate only on relevant information.  Bialystok emphases bilingualism doesn't prevent Alzheimer's disease, but her findings "meant that as the disease took root in their brains, they were able to continue functioning at a higher level."
