Bilingualism delays Alzheimer's, says study

Bilingualism delays Alzheimer's, says study - PakTribune: For the first time, Toronto scientists have physical evidence that people who speak more than one language could delay the onset of Alzheimer's disease than their monolingual counterparts.
The researchers at St. Michael's Hospital found that bilingual people have twice as much brain damage as unilingual people before they exhibit symptoms of Alzheimer's disease.
"This is unheard of – no medicine comes close to delaying the onset of symptoms and now we have the evidence to prove this at the neuroanatomical level," said lead researcher Dr. Tom Schweizer, a neuroscientist at St. Michael's Hospital.
To conduct the study, the researchers studied the CT scans of 40 patients whose cognitive skills — including attention, memory, planning and organizational abilities — were found on testing to be similar.
