This paper reviews how speaking, learning, managing, and switching between multiple two or more languages may promote neuroplasticity in the brain. Research suggests that bilingual and multilingual individuals' experiences promote executive function, cognitive flexibility, and neural connections. This paper also examines similarities and differences between monolingual, bilingual, and multilingual individuals through cognitive testing and brain imaging. An enhanced review is on language switching because one must regularly switch through language systems which ultimately can promote neuroplasticity. In conclusion, research suggests that regularly switching and using different languages may act as a form of cognitive training which supports neuroplasticity and long term brain health. However, factors such as language proficiency, age of acquisition, frequency of use can influence these effects.
