A new initiative aimed at helping people re-learn language after suffering a stroke has shown the success of the learning may depend largely on which language the stroke sufferer is trying to learn.

Stroke sufferers often lose the ability to speak or remember events, but how difficult or easy it is to re-learn language can depend on which part of the brain was affected by the stroke and which language is being learnt.

Professor Anthony Kong from the University of Central Florida noticed this when working in Singapore. He found a big difference in stroke patients' symptoms depending on whether they spoke English or Chinese.

PROFESSOR KONG: 'In Chinese there is a higher portion of right hemisphere activation, in terms of processing the language, and this contrasts with English or other Latin based languages in which most of the activations are on the left side of the brain.'

He says brain imaging techniques show tonal languages, such as Chinese, make more use of the right side of the brain, whereas the processing for Latin based languages, such as English, tends to occur in the left side. This means for Chinese speakers, most of the medical research on re-learning language after a stroke may not be relevant to them, as it comes from investigations with English speakers.

Professor Kong is now about to start the first Chinese specific research project on the way brain damage affects speech. He hopes this will lead to better after stroke therapy for speakers of Chinese and other tonal languages.
