Nov, 2010 — A Canadian science team has found dramatic evidence that speaking two languages can help delay the onset of Alzheimer's symptoms by as much as five years.
The latest study, led by Baycrest's Rotman Research Institute, examined the clinical records of more than 200 patients diagnosed with probable Alzheimer's disease.
The researchers found that those who have spoken two or more languages consistently over many years experienced a delay in the onset of their symptoms by as much as five years. The study is published in the November 9th issue of the science journal 'Neurology'.
The science team includes cognitive researcher Dr. Fergus Craik of the Rotman Research Institute; Dr. Ellen Bialystok of York University, an expert in bilingualism research; and Dr. Morris Freedman, a clinician in the diagnosis and treatment of Alzheimer's and other dementias.
