Learning another language can promote brain growth, stave off dementia, boost memory, improve attention and more…
Language centres in the brain actually grow as a result of successful language learning. The better you learn, the more those vital areas of the brain grow (Mårtensson et al., 2012).
2. Starve off dementia
Bilingualism delays Alzheimer’s disease in susceptible people by as much as five years (Craik et al., 2010). Seems incredible, but the studies are continuing to support this result. To put this in context: the effect on dementia of learning another language is much greater than anything achievable with the latest drugs.
3. Boost your memory
Babies brought up in a bilingual environment have stronger working memories than those brought up with only one language (Morales et al., 2013). This means they are better at mental calculation, reading and many other vital skills.
4. Better multi-tasking
Bilingual people can switch from one task to another more quickly. They show more cognitive flexibility and find it easier to adapt to unexpected circumstances (Gold et al., 2013)
5. Increased attention
Bilinguals have stronger control over their attention and are better able to limit distractions (Bialystok & Craik, 2010).
