Being bilingual 'aids stroke recovery'24 November 2015 09:42
Being bilingual may help the way people recover from strokes
Bilingual stroke victims are far likelier to regain their brain functions than those who can only speak one language, new research suggests.
Researchers say their findings suggest that the mental challenge which goes with speaking more than one language may improve the way the brain deals with strokes, dementia and other damaging influences.
The team - based at the University of Edinburgh and the Nizam Institute of Medical Sciences in Hyderabad, India - studied data from over 600 stroke patients.
They found that among those who speak two or more languages, just over two fifths (40.5%) went on to regain their normal mental functions.
But among stroke victims who only speak one language, the proportion was just under one in five (19.6%), the study shows.
The team factored in patients' ages as well as other things such as smoking, diabetes and blood pressure to make sure their results were not attributed to some having a healthier lifestyle.
The researchers say the proportion of bilingual patients whose cognitive functions remained intact after their stroke was over twice as high as for monolingual ones. The likelihood of post-stroke cognitive impairments, meanwhile, was higher among those who only speak one language.
The study's co-author, Thomas Bak, says people who are bilingual communicate by inhibiting one language while activating another. Switching between languages, he adds, keeps the brain in almost constant training, which could be a factor in helping people recover from strokes.

Presumably, the bigger "switch" between your first and second languages,the more agile your brain will need to be. French +Spanish would not be such a good combination as, say, Russian + Welsh as far as as stroke recovery is concerned.
In fact I think that the Welsh language with its strange words, complex grammar, mutation system and the like must be one of the world's top brain-twisters. Almost as mysteriously wonderful as Euler's Equation.
Slightly fitting in with this train of thought, here's a video I might have put on sometime in the past .. it's Alex Jones suddenly switching to Welsh in The One Show ... the look on his face is a sight to see ..
Mind you, I suspect that other skills might do a similar job ..especially playing musical instruments.. I've done lots of that, and I reckon that a hell of a lot of brain-woggling goes on when you play a guitar or a euphonium or an ocarina, or when you switch over from guitar to bass, or stick the guitar into different tunings, or sight-read.
Which reminds me .. it's music time ... and it's Geraint Jarman and "Cenhadon Casineb" .... fideo rhyfeddol, gyda llaw ..
