The study was concerned with the ability to discourse in a group of 10 patients with minor or moderately severe disturbances in Alzheimer disease and in a control group of healthy subjects. The aim the study was to answer the question whether patients with this disease have language deficits, and if they have, then at what level they appear and what is their influence on the communication ability. The experimental task included production of a narrative and a procedural discourse. The results were analysed from the standpoint of grammar of clauses and their informative contents. The analysis showed that the patients had no deficit in respect to the extent of the discourse, its complexity and grammar correctness. However, errors were found in the contents of the discourse. In particular, the discourse of the patients had a greater number of irrelevant and incorrect propositions. The possible explanation of the demonstrated deficit pattern is discussed stressing the importance of progmatic and cognitive factors. The conclusion is that language disorders in these patients should not be regarded as a type of aphasia.
该研究关注了一组10名患有轻度或中度阿尔茨海默病障碍的患者以及一组健康对照者的话语能力。该研究的目的是回答患有这种疾病的患者是否存在语言缺陷，如果存在，那么缺陷出现在什么层面以及它们对交流能力有何影响。实验任务包括生成一篇叙述性话语和一篇程序性话语。从从句语法及其信息内容的角度对结果进行了分析。分析表明，患者在话语长度、复杂性和语法正确性方面没有缺陷。然而，在话语内容中发现了错误。特别是，患者的话语中有更多不相关和不正确的命题。讨论了所显示的缺陷模式的可能解释，强调了语用和认知因素的重要性。结论是，这些患者的语言障碍不应被视为一种失语症类型。
