A new study has found the association of delay in the onset of Alzheimer's with the ability to speak two languages.

The study carried out by researchers from Toronto's Baycrest's Rotman Research Institute discovered that those people who speak two languages have the advantage of delaying Alzheimer's symptoms by five years.

The researchers based their findings on the analysis of the clinical records of more than 200 patients, who were detected with the feasibility of Alzheimer's disease. It was found that those who used to speak two or more languages for many years had their Alzheimer's symptoms delayed.

The researchers said, “While bilingual Alzheimer's sufferers still show deteriorating pathology, their ability with two languages seems to equip them with compensatory skills to hold back the tell-tale symptoms of Alzheimer's”.

The symptoms of Alzheimer's include memory loss, confusion and trouble in solving problem and making plans.

Fergus Craik, the lead author of the study expressed that the findings of the study didn’t mean that people speaking two or more languages had no risk to Alzheimer's or other dementias, but the ability just helped them in reserving their cognitive abilities in the brain that delayed the onset of the disease.
