A new study published in the journal Cerebral Cortex suggests people who speak two languages have more gray matter in the executive control region of the brain.
In past decades, much has changed about the understanding of bilingualism. Early on, bilingualism was thought to be a disadvantage because the presence of two vocabularies would lead to delayed language development in children. However, it has since been demonstrated that bilingual individuals perform better, compared with monolinguals, on tasks that require attention, inhibition and short-term memory, collectively termed "executive control."
This "bilingual advantage" is believed to come about because of bilinguals' long-term use and management of two spoken languages. But skepticism still remains about whether these advantages are present, as they are not observed in all studies. Even if the advantage is robust, the mechanism is still being debated.
I find learning more languages makes it easier to acquire new ones because you get better at it, but idiomatic speech and use of metaphor seem to take a real hit.

I would say they're pretty similar in their affect on the brain, except it's probably more analogous to speaking Spanish to a Portuguese speaker. If you go slow you can make yourself understood, but if you go fast you miss the bigger picture and finer points, in much the same way that if you know Java you'll be able to tell where a loop is in Perl, but the regex's might still make you scratch your head.
