An examination over time of language and discourse production abilities following right hemisphere brain damage

Discourse production after right brain damage: Gaining a comprehensive picture using a multi-level processing model

“…Mackenzie & Brady, 2008). Discourse sample length in speakers after RBD is reportedly similar to, longer or shorter than that of NBD speakers (Brady, Armstrong, & Mackenzie, 2006;Cherney, Drimmer, & Halper, 1997;Lehman Blake, 2006;Marini et al, 2005;Uryase, Duffy, & Liles, 1990). Note that Trupe and Hillis (1985) found extremes of copious digressive output and a paucity of speech in their group of participants with RBD.…”

“…Note that Trupe and Hillis (1985) found extremes of copious digressive output and a paucity of speech in their group of participants with RBD. Time post-onset may be a significant factor; reduced speech output occurred up to six months postonset (Brady et al, 2006) or conversely, returned to normal at one year post-onset . Participants with RBD are generally considered to have little or no impairment of syntactic skills.…”

“…The relatively few studies examining complex syntax in these speakers have been inconclusive; they displayed less syntactically complex picture story narratives (Joanette, Goulet, Ska, & Nespoulous, 1986) but more complex narrative and procedural discourse (Osiejuk, 1989). However, no differences in clausal embedding between normal and participants with RBDs were found in narratives, procedures and conversations (Brady et al, 2006;Marini et al, 2005;Sherratt & Penn, 1990). 5) Clausal structure -The production of main, right-and left-branching clauses has been examined in older speakers but not, as far as is known, in participants with RBD.…”

Communicative Clusters after a Right-Hemisphere Stroke: Are There Universal Clinical Profiles?

“…Although this variable was the most heterogeneous, this could provide hints regarding the profile of evolution of the manifestation, even though that profile could be very heterogeneous among individuals. Very little research has been conducted so far regarding language recovery over time in individuals with RBD and mismatching results can be found in the literature: one study [37] demonstrated that no spontaneous recovery was found in discourse until 6 months after onset, while another [38] reported significant improvement between 1, 6 and 12 months. In this study, it seems that patients in the most chronic phase after stroke exhibit a profile characterized mainly by conversational and emotional prosody impairments, while other disorders seem to diminish.…”

Exclusion and Inclusion Criteria for People with Aphasia in Studies of Depression after Stroke: A Systematic Review and Future Recommendations

“…Contemporary clinical assessment tends to focus on the analysis of connected (and often spontaneous) discourse with the aim of providing descriptive evaluations of individuals' communicative and pragmatic abilities [40] . This approach may be limited in replicability (although early efforts to demonstrate the relative stability of such approaches has proved promising [41,42] ). However, in clinical practice, where replicablility is less essential but there is a greater imperative to be inclusive, speech and language specialists generally provide tailored assessments of patients' communication needs, which would be pertinent to their participation in depression diagnosis procedures.…”
