Learning another language helps protect the brain against dementia, according to a new study (The Telegraph, 29 March 2012)

How?

Switching between two languages is a high-level executive function for the brain, like multitasking or concentrating intensely (or studying vocab!).

Practicing this skill by speaking two languages “rewires” the brain to create a more efficient network that allows for better cognitive control over the course of a lifetime.

It’s like a workout for your brain!

Are you studying English as a second (or third, or fourth) language?  What other benefits of being bilingual can you think of?
