Lifetime of speaking a 2nd language may boost aging brain
from HealthDay News via U.S. News & World Report
A lifetime of speaking two languages may help keep older people's brains sharper, researchers report. The new study included healthy seniors, aged 60 to 68, who had spoken two languages (bilingual) or just one language (monolingual) since childhood. Their brain activity was monitored as they switched from one mental task to another. Compared to those who were monolingual, the bilingual seniors were faster at switching from one task to another and used less energy in the frontal parts of their brain when making the switch, according to the study in the Journal of Neuroscience.
