“…In general, stroke narratives were more coherent and clearer in Greek compared to English, but this finding was not unexpected, since the Greek language was better preserved for most participants several years after stroke and is currently considered their dominant language despite residing in Australia and living in an English-dominant society. The finding that bPWA show no major difficulties producing coherent narratives in both their L1 and L2 is in line with what has been consistently reported by Ulatowska and colleagues [14, 22-25] for monolingual English speakers with mild-moderate aphasia.…”

“…The narratives of bilingual immigrants with aphasia were evaluated for global coherence, clarity, temporal-causal sequencing and referential and evaluative language in both their native language Greek (L1) and their second language English (L2) based upon work pioneered by Ulatowska and colleagues [14, 22-25] for monolingual speakers of English with aphasia. In addition, a code-switching category was incorporated in the narrative analyses given the bilingual status and cultural identity of both the PWA and the clinician collecting the stories [4, 35].…”

“…A growing body of work on stroke narratives in aphasia has been carried out by Ulatowska and colleagues [14, 22-25]. Most of the stroke stories collected by this team of researchers were produced by middle-aged, English-speaking Caucasian and African-American adults with mild-moderate aphasia.…”

“…Most of the stroke stories collected by this team of researchers were produced by middle-aged, English-speaking Caucasian and African-American adults with mild-moderate aphasia. The research findings have covered three broad themes: (i) overall narrative competence [22, 24], (ii) coherence of information [14, 22] and (iii) use of linguistic/non-linguistic evaluative devices to assign prominence [23, 25] to the stroke narrative. In general, the findings revealed that individuals with mild to moderate aphasia demonstrate relatively intact narrative competence in relation to coherence, clarity and temporal-causal structure despite difficulties with reference [1, 24, 25].…”

“…For speech-language therapists a positive relationship with PWA promotes the exchange of information and ideas about assessment needs and/or treatment goals and progress [20]. Personal event narratives are also considered ecologically salient tasks since through everyday experience, contextual details, person-revealing characteristics and information about feelings and meanings are shared [21, 22]. …”

Objective: For people with aphasia (PWA) and their significant others, narratives are intricately intertwined with quality of life, culture, and social participation. This paper reports stories told by bilingual people with aphasia (bPWA), describing the events or consequences of a stroke on their lives. Patients and Methods: Six participants with chronic mild-moderate anomia (mean age 70 years) spontaneously produced a narrative recounting their personal experience of stroke in their native language (Greek) and in their second language (English). All bPWA had learned English in early adulthood upon migration from Greece to Australia, not through formal teaching but on the job (e.g., in the factory). The bPWA had lived in Australia for 46 years (average) and were less than 4 years post-stroke. Results: Narratives in the two languages underwent quantitative (number of propositions, noun/verb tokens) and qualitative analyses (ratings of coherence, ratings of clarity). Most bPWA produced coherent “tellable” stories despite disruptions in language because of aphasia. Overall, stories were better told (length, complexity of content, temporal-causal sequencing, reference) in Greek – their native language. Conclusion: The results have implications for policy-makers providing health and welfare services to ageing immigrant populations. The findings are also relevant to other countries that have large immigrant populations of stroke survivors.

Humans are uniquely able to retrieve and combine words into syntactic structure to produce connected speech. Previous identification of focal brain regions necessary for production focused primarily on associations with the content produced by speakers with chronic stroke, where function may have shifted to other regions after reorganization occurred. Here, we relate patterns of brain damage with deficits to the content and structure of spontaneous connected speech in 52 speakers during the acute stage of a left hemisphere stroke. Multivariate lesion behaviour mapping demonstrated that damage to temporal-parietal regions impacted the ability to retrieve words and produce them within increasingly complex combinations. Damage primarily to inferior frontal cortex affected the production of syntactically accurate structure. In contrast to previous work, functional-anatomical dissociations did not depend on lesion size likely because acute lesions were smaller than typically found in chronic stroke. These results are consistent with predictions from theoretical models based primarily on evidence from language comprehension and highlight the importance of investigating individual differences in brain-language relationships in speakers with acute stroke.
