雙語並用對健康有益! 可防止癡呆。 Learn a new language and stay healthy!
Would you learn a new language if it would help your health?
Learning another language does have its benefits.
現在科學家發現，說兩種語言還能延緩失智症的發。失智症病人中，有五至七成是阿茲海默症。阿茲海默症的英文全名是Senile Dementia of the Alzheimer Type，簡稱SDAT。 所以想要預防這種可怕的疾病，從年輕就要開始努力。
不過延緩不代表可以百分之百免疫，所以雙語人people who are bilingual不一定就不會罹患失智症，畢竟這個症狀與老化、環境、基因與生活習慣都有密切關連。但目前可以確定的是，雙語頻繁的交互使用，確實能強化腦力，鍛鍊腦袋許多其他或許用不到的部分，如此便能延緩失智的症狀。
Would you learn a new language if it would help your health? You may have heard that bilingual children actually have more brainpower更強大的腦力 than kids who grow up speaking only one language. But could speaking multiple languages help you at the other end of life生命的其他方面 as well? Neuroscientists神經科學家 now say yes. Bilingualism appears to protect against dementia失智症 and Alzheimer’s伊茲海默症 disease. In a recent study, Dr. Ellen Bialystok at York University found that in bilingual patients with dementia, the disease had a later onset than in monolingual單一語言 patients. On average, being bilingual delayed延緩 the disease by four to five years.
Why does being bilingual protect against抵禦，使免受 dementia? Regularly speaking two languages strengthens different parts of the brain. This exercise helps what neuroscientists call “executive control執行控制,” which refers to complex cognitive skills大腦的認知技巧 like planning, working memory, mental flexibility腦力彈性, and many other important functions. These skills are the first to disappear as we age, but some activities (like eating well, exercising regularly, and doing word puzzles) have been shown to stave off mental decline 避免腦部退化 in old age. Apparently, being bilingual has a similar impact.
Does your high school French class count? Sadly no. How often you speak a second language, and how well you know it, both influence to what degree being bilingual can protect against dementia. Other variables變數, like when a patient learned the second language, have not been examined.
Are you more likely to learn another language because it has positive health impact?
