Speaking two or more languages could help delay symptoms of Alzheimer’s by up to five years, Canadian researchers have found.
A study first published in the journal Neurology compared Alzheimer’s patients who are bilingual to those who speak only one language. Both groups demonstrated signs of cognitive deterioration consistent with Alzheimer’s disease, however those with a second language ability took up to five years longer to develop symptoms such as memory loss, confusion and difficulties with problem-solving and planning.
Scientists from Rotman Research Institute, who conducted the study, believe a second language could equip patients with important compensatory skills that can help keep cognitive loss at bay.
