 The purpose of this study is to examine the processing of discourse cohesion in problematic communication following traumatic brain injury (TBI), and to study how it relates to cognitive functions. Forty-five TBI patients without aphasia and thirty normal control subjects narrated 4-frame comic strips. We conducted quantitative and qualitative analyses of the narratives and the subsequent results were compared to the patients' scores on cognitive tests. There was no difference between the TBI and control subjects in the quantity of utterances, but the TBI subjects showed a significant decrease in the amount of appropriate information and the production of inference sentences. In addition, TBI subjects had difficulty in explaining the humor and story line of the comic strips, showing deficits in cohesion. These problems were related to a decrease in working memory and executive dysfunction. The findings suggested that discourse training after TBI needs to take into account the underlying cognitive dysfunction of the discourse deficits.
