Narrative Discourse cohesion in early stage parkinson s disease
Journal of Parkinson's disease, 2015Co-Authors: Charles Ellis, John C. Rosenbek, Bruce Crosson, Leslie Gonzalez J Rothi, Michael S OkunAbstract:Background Models of basal ganglia (BG) function suggest that expressive language deficits will likely and consistently present in BG disease. Disparities currently exist between the predictions of models of BG function in expressive language and data from studies of BG disease. Traditional expressive language assessment methodologies that emphasize measures of language form (word and sentence productivity) while not carefully considering how language is used, may only partially account for these disparities. Objective To use measures of cohesion to examine the use of cohesive markers in Narrative Discourse. Methods Twelve individuals with idiopathic Parkinson's disease (PD) were compared to 12 matched neurologically intact controls on measures of Discourse performance. Three Discourse samples (typical day, memorable vacation and family) were analyzed for measures of Narrative productivity, number of cohesive ties and cohesive adequacy. Mixed model analyses were completed for group comparisons. Results Group differences were not observed on measures of language form as measured by Narrative productivity, communication units, and number of cohesive ties produced. In contrast, group differences were observed in cohesive adequacy as individuals with PD produced a higher percentage of incomplete and erroneous cohesive ties relative the control subjects across Narratives. Conclusions These results support the conclusion that the BG in PD may have an executive role in expressive language use that can be disrupted without impacting language form.

Recovery of cohesion in Narrative Discourse after left-hemisphere stroke.
Journal of rehabilitation research and development, 2005Co-Authors: Charles Ellis, John C. Rosenbek, Maude Rittman, Craig BoylsteinAbstract: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.

The Natural History of Cohesion in Narrative Discourse after Stroke
2005Co-Authors: Charles Ellis, John C. Rosenbek, Maude Rittman, Craig BoylsteinAbstract:Little is known about the natural recovery of Narrative Discourse after stroke. While several studies have analyzed the recovery of language in individuals with aphasia, there are no known studies of the natural recovery of Narrative Discourse in individuals without diagnosed language disorders. In this study we evaluate the cohesiveness of Narrative Discourse in a cohort of individuals who have suffered a stroke without a diagnosed language impairment. We analyze their Narrative Discourse at three intervals post-stroke and report findings that provide insights into the subtle disruptions of language following stroke and the manner in which they change over time.

emerging Narrative Discourse skills 18 months after traumatic brain injury in early childhood
Journal of Neuropsychology, 2012Co-Authors: Nicolay Chertkoff Walz, Keith Owen Yeates, Gerry H Taylor, Terry Stancin, Shari L WadeAbstract:This study examined the longer term effect of traumatic brain injury (TBI), approximately 18 months post-injury, on emerging Narrative Discourse skills of 85 children with orthopaedic injury (OI), 43 children with moderate TBI, and 19 children with severe TBI who were between 3 years and 6 years 11 months at injury. Children with TBI performed worse than children with OI on most Discourse indices. Children with severe TBI were less proficient than children with moderate TBI at identifying unimportant story information. Age and pragmatic skills were predictors of Discourse performance.
