Alzheimer’s Prediction May Be Found in Writing Tests
Is it possible to predict who will develop Alzheimer’s disease simply by looking at writing patterns years before there are symptoms? According to a new study by IBM researchers, the answer is yes. And, they and others say that Alzheimer’s is just the beginning. People with a wide variety of neurological illnesses have distinctive language patterns that, investigators suspect, may serve as early warning signs of their diseases.
• Alzheimer’s disease 阿爾茨海默症
• symptoms 癥狀、症狀
• according to a new study 根據一個新研究
• a wide variety of 多種～的
• neurological illnesses 神經系統疾病
• distinctive language patterns 獨特的語言模式
• an early warning sign of ～的早期預警訊號
The researchers examined the subjects’ word usage with an artificial intelligence program that looked for subtle differences in language. It identified one group of subjects who were more repetitive in their word usage at that earlier time when all of them were cognitively normal. These subjects also made errors, such as spelling words wrongly or inappropriately capitalizing them, and they used telegraphic language, meaning language that has a simple grammatical structure and is missing subjects and words like “the,” “is” and “are.”
• word usage 詞彙使用情況
• subtle differences 細微差別
• artificial intelligence 人工智慧
• repetitive 重複的
• telegraphic language* 電報式語言
• simple grammatical structure 簡單的語法結構
*telegraphic language is speech during the two-word stage of language acquisition in children, which is laconic and efficient but lack of function words, tense and plural endings on nouns.
The members of that group turned out to be the people who developed Alzheimer’s disease. The A.I. program predicted, with 75 percent accuracy, who would get Alzheimer’s disease, according to results published recently in The Lancet journal EClinicalMedicine. “We had no prior assumption that word usage would show anything,” said Ajay Royyuru, vice president of health care and life sciences research at IBM Thomas J. Watson Research Center in Yorktown Heights, N.Y., where the A.I. analysis was done.

這群人後來都患上了阿爾茨海默症。根據《柳葉刀》(The Lancet)子刊《臨床醫學》(EClinicalMedicine)最近發表的研究結果，該人工智慧能夠預測誰將患上阿爾茨海默症，準確率達75%。「我們之前沒有想到用詞情況還有這個用途，」紐約州約克敦高地的IBM托馬斯·沃森研究中心(IBM Thomas J. Watson Research Center)醫療保健和生命科學研究副總裁阿賈伊·羅伊尤魯(Ajay Royyuru)說。人工智慧分析就是在該中心進行的。
