| Research Abstract |
The purpose of this research was to investigate methods assessing cognitive-communicative functions following traumatic brain injury. In first part of present research, nature of cognitive-communicative disorders and their contribution to psychosocial outcome were examined. Patients with diffuse brain injury as well as those with focal brain injury showed narrative discourse dysfunction as communication problems. They failed to establish logical links between events in a story, resulting in a narrative which was disjointed and inconclusive. Significant correlations were found between performance scores of narrative discourses and measures of attention, memory and executive functioning. Psychosocial outcome was related to the discourse dysfunction severity. A Narrative Discourse Test of Brain Injury was designed based on these results. In second part of present research, cognitive functions following brain injury were examined. Most patients with diffuse brain injury demonstrated cognitive-communicative disorders. Memory disorder was most common cognitive consequences in those patients. Patients with memory disorders as well as disorders of executive functioning achieved lower level of psychosocial outcome and demonstrated longer duration of post-traumatic amnesia than those with memory disorder only. A Uniform Data Set of Cognitive-Communicative Functions After Brain Injury and a Cognitive-Communicative Function Screening Test of Brain Injury were designed based on results through present research.
