话语模式-所反映的命题，衔接手段的使用，并在连贯性的判断-在6个良好的老年人和6例老年痴呆症的阿尔茨海默型（SDAT）在主题为中心的采访中的讲话进行了比较。与健康老年人相比，SDAT患者使用的词汇和会话转折明显更多。访谈者在访谈SDAT患者时也使用了更多的词汇和转折，使这些访谈比老年对照组更长，更具互动性。虽然没有发现命题形式和衔接手段的显着差异，SDAT患者的衔接中断的模式被确定为与以前指出的语言溶解模式一致。四个听众的连贯性判断显示两组之间存在显着差异。语篇连贯性的缺失与语篇衔接中断的一种类型--缺失成分有关。这表明，不连贯的部分原因可能是丧失了在对话中发展主位结构的能力。SDAT不仅导致语言能力受损，而且还导致话语能力受损，从而导致阿尔茨海默病患者的言语不连贯。
Patterns of discouse- as reflected in the use of propositions, cohesion devices, and in judgements of coherence-in the speech of 6 well elderly and 6 patients with senile dementia of the Alzheimer type (SDAT) during topic-centered interviews were compared. Compared to the well elderly, SDAT patients used significantly more words and conversational turns. The interviewer also used more words and turns when interviewing SDAT patients, making those interviews more lengthy and more interactive than those of the elderly comparison group. Although significant differences in propositional form and cohesion devices were not found, a pattern of cohesion disruptions in SDAT patients was identified that appears consistent with previously noted patterns of language dissolution. Coherence judgements by four listeners showed significant differences between the two groups. The breakdowns in coherence were related to one subtype of cohesion disruption, missing element. This suggests that incoherence may result in part from a loss of the ability to take the listener''s perspective in developing thematic structure during conversations. It is argued that SDAT results not only in the impairment of linguistic abilities but also in the impairment of discourse abilities that contribute to Alzheimer patient''s incoherent speech.
