Being Bilingual Changes the Architecture of Your Brain

It is interesting to know that being bilingual or multilingual helps develop your brain's cognitive reserve.

According to Bialystok, who received the prestigious Killam Prize for her research in 2010, there is even preliminary evidence that being bilingual can improve your brain by causing valuable changes in brain structure: speaking two languages can cause actual physical changes in the brain that result in better cognition and brain health.

So if you're interested in learning another language, go for it. However, more research is needed before it's known whether learning a second language later in life has the same protective effect as might a lifetime of speaking a second language.
