The study, published in the American Heart Association journal Stroke, found 'results support the notion of a protective role of bilingualism in the development of post-stroke cognitive impairment'.

研究发表在美国心脏协会的《中风》杂志上，研究发现：“该结果肯定了这一概念——双语对中风后认知障碍的发展具有保护作用。”

It is the first time a study has been done looking at the relationship between the number of languages spoken and a patient's cognitive outcome after stroke.

这是首次有研究关注“会说几种语言”与“中风后患者的认知程度”之间的关系。

'The percentage of patients with intact cognitive functions post-stroke was more than twice as high in bilinguals than in monolinguals,' the paper said.

该论文称，“中风后认知功能未受损的双语患者的百分比数量是单语患者的两倍多。”

'In contrast, patients with cognitive impairment were more common in monolinguals.'

“相反，认知功能障碍在单语患者中更常见。”

Researchers believe the study, which was funded by the Indian Council of Medical Research, suggests the mental challenge of speaking multiple languages can boost cognitive reserve - an improved ability of the brain to cope with damaging influences such as stroke or dementia.

这项调查由印度医学研究委员会提供资金支持。研究人员认为，该研究说明多语能力对神经构成一种挑战，该挑战提高了认知储备——进而改进了大脑功能，能应对像中风或痴呆这种疾病的破坏性影响。
