A study reveals that people who can speak a second language may delay Alzheimer’s disease for as many as five years longer than those who speak only one language. Scientists believe the knowledge of two languages keeps the brain in a state of constant activity, as it learns when to use one language and inhibit the other.
People who are not bilingual can exercise the brain in others ways to create this same effect, by playing word games such as crosswords, or completing other brain exercises daily. Scientists believe that most memory loss and diminishing of brain function can be attributed to a decrease in use.
