创伤性脑损伤（TBI）通常与沟通障碍有关。在患有严重TBI的非失语症患者中观察到的不连贯和贫乏的语言与文本层面的全球信息组织问题有关。本研究旨在分析一组中度创伤性脑损伤（modTBI）患者的叙述性话语障碍特征。招募了10名患有modTBI的非失语症说话者和20名神经系统完整的参与者进行实验。他们的认知、语言和叙述技能都得到了全面的评估。modTBI的人表现出正常的语音，词汇和语法技能。然而，他们的叙事特点是较低的词汇信息水平和更多的本地和全球连贯性的错误，有时，使他们的叙事模糊和模棱两可。这些叙事困难和WCST上的持续性和非持续性错误之间存在显着的相关性。这些障碍证实了以前的研究结果，这表明在这些患者的认知和语言处理之间的接口，而不是一个特定的语言障碍的赤字。
Traumatic brain injuries (TBIs) are often associated with communicative deficits. The incoherent and impoverished language observed in non-aphasic individuals with severe TBI has been linked to a problem in the global organization of information at the text level. The present study aimed to analyze the features of narrative discourse impairment in a group of adults with moderate TBI (modTBI). 10 non-aphasic speakers with modTBI and 20 neurologically intact participants were recruited for the experiment. Their cognitive, linguistic and narrative skills were thoroughly assessed. The persons with modTBI exhibited normal phonological, lexical and grammatical skills. However, their narratives were characterized by lower levels of Lexical Informativeness and more errors of both Local and Global Coherence that, at times, made their narratives vague and ambiguous. Significant correlations were found between these narrative difficulties and the production of both perseverative and non-perseverative errors on the WCST. These disturbances confirm previous findings which suggest a deficit at the interface between cognitive and linguistic processing rather than a specific linguistic disturbance in these patients.
