Summary
Aging is a multidimensional process that introduces biological, social, and cognitive changes. The cognitive changes individuals experience during healthy aging are impacted by one’s lifestyle and patterns of behavior. In this chapter, we explore how multilingual language use uniquely contributes to cognitive aging and may stave off cognitive and neurological declines that commonly occur as we age. To this end, we first examine the range of executive functions that are impacted by multilingualism across the lifespan. Next, we explore the neurological implications of cognitive aging by outlining three neurocognitive mechanisms involved in aging, namely cognitive reserve, maintenance, and compensation. Integrating research from the available literature on healthy and pathological aging, we consider whether multilingualism strengthens and alters the neural bases of cognitive aging. As research on multilingual aging is nascent, our chapter ends with an agenda for future research that considers factors unique to multilingualism.
