Bilingualism comes in many shapes and forms

Being bilingual does affect your brain, but it depends on how you use it.

Some bilinguals learn a second language from birth. Others learn a second language much later. Some bilinguals continuously need to switch between their languages, while others speak one language at home and another at work. Different language experiences have distinct effects on how the brain adapts and performs. Moreover, these adaptations are dynamic with continued and changing experiences.
