Abstract

Naming impairment is a hallmark of logopenic primary progressive aphasia (lvPPA), yet its effects in bilingualism remain understudied. This study examined naming accuracy in a 78-year-old Chinese-English bilingual woman with lvPPA over two years using a modified Boston Naming Test. Naming accuracy was higher in her second, but more frequently used language (English) than her first, but less frequently used language (Chinese). Regression analyses revealed that familiarity predicted naming in Chinese, while word length and age of acquisition influenced English. Decline was linked to age of acquisition in Chinese and emotional properties in English, highlighting language-specific patterns in bilingual lvPPA.

双语语素缺乏症原发性进行性失语症的命名准确性和下降的心理语言学预测因素：一项跨语言案例研究。

命名障碍是语源性原发性进行性失语症（lvPPA）的标志，但其对双语者的影响仍未得到充分研究。本研究使用改良的波士顿命名测试对一名78岁的lvPPA中英双语女性进行了两年多的命名准确性检查。第二种语言（英语）的命名准确率高于第一种语言（中文），但使用频率较低。回归分析表明，熟悉度对汉语命名有预测作用，而单词长度和习得年龄对英语命名有影响。下降与汉语习得的年龄和英语的情感属性有关，突出了双语lvPPA的语言特异性模式。

期刊介绍： Neurocase is a rapid response journal of case studies and innovative group studies in neuropsychology, neuropsychiatry and behavioral neurology that speak to the neural basis of cognition. Four types of manuscript are considered for publication: single case investigations that bear directly on issues of relevance to theoretical issues or brain-behavior relationships; group studies of subjects with brain dysfunction that address issues relevant to the understanding of human cognition; reviews of important topics in the domains of neuropsychology, neuropsychiatry and behavioral neurology; and brief reports (up to 2500 words) that replicate previous reports dealing with issues of considerable significance. Of particular interest are investigations that include precise anatomical localization of lesions or neural activity via imaging or other techniques, as well as studies of patients with neurodegenerative diseases, since these diseases are becoming more common as our population ages. Topic reviews are included in most issues.
