As such, impairment of this ability as a result of stroke can be debilitating and disabling to the patients as well as significant others. Agrammatism is deficit in the use and processing of grammatically coherent syntactic structures following damage to the Broca’s complex or region. Most studies have traditionally emphasized monolingual patients, with bilingualism now receiving increased attention. However, few studies have specifically investigated the effect of minor stroke on agrammatic bilingual individuals. This study examined an agrammatic Yoruba- English bilingual patient with minor stroke with a view to describing their sentence production (deficit). The findings strongly support the existence of distinct language-specific lexical-subsystem centres in the Broca’s complex for native and acquired languages (Yoruba-English) whereas both languages are likely connected to a single semantic system in the anterior temporal lobe and its surrounding regions. Furthermore, acquired language is more susceptible to brain damage than native language. This might imply that severity of deficit in speech production in both native and acquired language of bilingual aphasics may be determined by the size of lesion in the Broca’s complex or region.展开更多

Some therapies aimed at the improvement of cognitive functions can facilitate the recovery of NFA patients＇ damaged linguistic functions. Some studies have shown that with music cues NFA patients could fluently sing their familiar songs but could not read the lyrics, consistent with studies of proverbs and prayer） Our previous research has shown that highly related voice cues can improve NFA patients＇ verbal expression.2 These results indicate that the improvement of NFA patients＇ speech production may benefit from regaining the extraction of phonological encoding that has already been preserved in memory, rather than re-study of the language.展开更多
