Little is known about the recovery of narrative discourse after stroke. While several studies have analyzed the recovery of language in individuals with aphasia, few known studies exist on the recovery of narrative discourse in stroke survivors, particularly those who have not been diagnosed with aphasia. In this study, we evaluated the cohesiveness of narrative discourse in a cohort of individuals who had suffered a left-hemisphere stroke and had not been diagnosed with expressive language impairment. We analyzed their narrative discourse at 1, 6, and 12 months poststroke. Our findings indicate that, while the mean number of cohesive ties in narrative discourse remained generally constant during the first year poststroke, the percentage correct use of cohesive ties increased significantly during the same time period. These findings suggest that subtle disruptions in expressive language can be present initially in narrative discourse, and recovery from these disruptions can occur naturally over time.
关于中风后叙事话语的恢复情况，人们所知甚少。虽然有几项研究分析了失语症患者的语言恢复情况，但关于中风幸存者，尤其是那些未被诊断为失语症的患者的叙事话语恢复情况，已知的研究很少。在本研究中，我们评估了一组左半球中风且未被诊断为表达性语言障碍的个体的叙事话语连贯性。我们在中风后1个月、6个月和12个月分析了他们的叙事话语。我们的研究结果表明，虽然叙事话语中连贯关系的平均数量在中风后的第一年总体上保持不变，但连贯关系的正确使用百分比在同一时期显著增加。这些发现表明，表达性语言的细微干扰最初可能出现在叙事话语中，并且随着时间的推移，这些干扰会自然恢复。
