If you haven’t had enough good reasons to learn a new language, here are two more. Did you know that speaking a second language can not only help to prevent mental aging but also delay the onset of Alzheimer’s disease by up to five years?
Research in cognitive science shows that it is possible to build a so called “cognitive reserve” that helps the brain to prevent mental aging and to resist degenerative diseases like dementia or Alzheimer’s when you are getting old.
This cognitive reserve is build up by literally using and hence “muscling” your brain. Mental exercises like speaking multiple languages, remembering different words etc lead to more neurons and bigger brains. This surplus will then help to fight of degenerative disease later in life.
This also underlines how important it is that children start learning a second language early on in life. The sooner people start using their brain, the more cognitive reserve will be build up for the later stages in life.
