Bilingualism Can Help Delay Onset of Alzheimer's

Alzheimer's patients who speak more than one language have a better chance of delaying the onset of severe deterioration than their monolingual counterparts.

Alzheimer's patients who speak more than one language can delay the onset of severe deterioration than their monolingual counterparts, according to a new research by Toronto scientists.

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.

Alzheimer's disease is a progressive neurodegenerative disease affecting memory and thinking and making the person increasingly dependent on others.

"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.

Brilliant Human Brain
The most amazing and complex organ in the entire universe, the human brain continues to remain an enigma.

Half the patients were fluently bilingual while the other half spoke only one language.

The scans of the bilingual patients showed twice as much atrophy in areas of the brain known to be affected by Alzheimer's.

Diseases Related to Old Age
Ageing is referred to the accumulation of changes that brings a person closer to death.

Schweizer said that bilingual people are constantly using their brain and keeping it active, which may contribute to overall brain health. That's why many physicians encourage older people to do crossword puzzles or Sudoku.

Previous observational studies have found that bilingualism delays the onset of Alzheimer's symptoms by up to five years, but this is the first to find physical proof through CT scans.

Daily Vit B Pill Can Help to Keep Alzheimer's Disease at Bay
A daily dose of vitamin B could greatly slow the onset of dementia and guard against Alzheimer's disease.

Although being bilingual appears to stave off onset of the symptoms, Schweizer stressed that bilingualism does not prevent someone from developing Alzheimer's. Once symptoms start to appear in bilingual people, it is not clear whether the disease progresses at an accelerated rate.

The findings appear online in the journal Cortex.
