Although studies carried out in the beginning of the twentieth century showed that speaking two or more languages could potentially have negative effects on people’s cognitive abilities, more recent studies have proved quite the opposite: latest research shows that being bilingual is definitely beneficial!
Children who speak more than one language develop empathy earlier than those who only speak one. But the advantages of having more languages at your disposal don’t stop in childhood: bilingual adults have been found to be able to focus more than their monolingual peers, they are better at multitasking, and last but not least, their memory is much better.
Speaking of memory! Some studies show that being bilingual delays the onset of Alzheimer’s and dementia in general by years.
