People who speak more than one language and who develop dementia tend to do so up to five years later than those who are monolingual, according to a study.
Scientists examined almost 650 dementia patients and assessed when each one had been diagnosed with the condition.
They found people who spoke two or more languages experienced a later onset of Alzheimer's disease, vascular dementia and frontotemporal dementia.
The bilingual advantage extended to illiterate people.
The scientists said it confirmed the observed effect was not caused by differences in formal education.
