Abstract

This article reviews recent evidence for the relationship between extralinguistic cognitive and language abilities in dementia. A survey of data from investigations of three dementia syndromes (Alzheimer's disease, semantic dementia and progressive nonfluent aphasia) reveals that, more often than not, deterioration of conceptual organization appears associated with lexical impairments, whereas impairments in executive function are associated with sentence- and discourse-level deficits. These connections between extralinguistic functions and language ability also emerge from the literature on cognitive reserve and bilingualism that investigates factors that delay the onset and possibly the progression of neuropsychological manifestation of dementia.

摘要

本文综述了近期关于痴呆症患者语言外认知能力与语言能力之间关系的证据。对三种痴呆综合征(阿尔茨海默病、语义性痴呆和进行性非流利性失语)调查数据的研究表明,概念组织的退化往往与词汇损伤有关,而执行功能的损伤则与句子和语篇层面的缺陷有关。语言外功能与语言能力之间的这些联系也出现在关于认知储备和双语现象的文献中,这些文献研究了延迟痴呆症神经心理学表现的发作及可能进展的因素。
