Is bilingualism protective for adults with aphasia?

Publication date: Available online 20 January 2020Source: NeuropsychologiaAuthor(s): Maria Dekhtyar, Swathi Kiran, Teresa GrayAbstractThe bilingual advantage proposes that bilingual individuals have enhanced cognitive control compared to their monolingual counterparts. Bilingualism has also been shown to contribute to cognitive reserve by offsetting the behavioral presentation of brain injury or neural degeneration. However, this effect has not been closely examined in individuals with post-stroke or post-TBI aphasia. Because bilingualism has been suggested as a factor of cognitive reserve, it may provide protective mechanisms for adults with aphasia. In the current study, evidence for the bilingual advantage was examined in 13 Spanish-English bilingual healthy adults (BHA) compared to 13 English monolingual healthy adults (MHA). Additionally, evidence for cognitive reserve as defined by a bilingual advantage was examined in 18 Spanish-English bilingual adults with aphasia (BAA) compared to 18 English monolingual adults with aphasia (MAA) who were otherwise matched on their age, education, language impairment, and non-verbal executive functions. All participants completed a non-linguistic cognitive control task that included congruent and incongruent conditions. Results indicated no bilingual cognitive control advantage on reaction times in healthy adult groups; however, BAA were faster than MAA, suggesting that bilingualism may contribute to cognitive reserve in adults with ...

We assessed the outcome of dysphagia rehabilitation in all the 139 patients with post-stroke dysphagia admitted to our Neurorehabilitation Unit during 2 years (2017 and 2018), divided into two groups: old (aged 65–84 years) and oldest-old (aged 85 or above). We studied which factors predicted dysphagia improvement in the two groups. The potential association of improvement with type of discharge was also evaluated. On admission, ‘old’ patients had more frequently aphasia (P = 0.02) and less frequently dysarthria (P = 0.03); ‘oldest old’ had more severe pressure ulcers (P = 0.008), higher level...

CONCLUSIONS &IMPLICATIONS: PWA have a variety of activity participation goals that can be integrated into intervention plans. Dependence on proxy respondents should be reduced as much as possible to support self-determination for PWA. What this paper adds What is already known on the subject Achieving activity participation goals is a key factor in QOL for PWA, but communicating about participation goals can be difficult for many of them. Because proxy reports by caregivers may not accurately reflect the interests and participation goals of PWA, this study examined how both PWA and their caregivers responded to an apha...

AbstractTests and batteries used in the evaluation of language impairments are overly complex and often ineffective (too difficult) in the assessment of post-stroke patients affected by severe aphasia (global aphasia). The present study reports details on the construction and standardization of a new Italian battery of tasks, specifically designed to assess severe lexical disorders in acquired aphasia (Battery for the Assessment of Severe Acquired Lexical Damage in Italian, BASALDI). The battery is composed of a common set of 64 stimuli (concrete nouns), belonging to both living and non-living categories, and consists of f...

Conclusions: Aphasia disrupts usual care. Health professionals want to help but are working in a non-optimal environment where communication and patient-centred care are not adequately resourced.IMPLICATIONS FOR REHABILITATIONCurrent hospital systems and ward culture make it difficult to offer patient-centred care to patients with aphasia.Health professionals want to help patients with aphasia but are working in an environment where patient-provider communication is not adequately resourced.As a result, health professionals dread, limit or avoid talking with patients with aphasia.Health professionals need support which may...

CONCLUSION: In summary, the method applied to nCT scans performed in the acute stage of stroke provided robust and accurate information about brain lesions' location and size, as well as quantitative values. We found that nCT and VBQ analyses areeffective for identifying neural signatures of concomitant language impairments at the individual level, and neuroanatomical maps of aphasia at the population level. The signatures explicate the neurophysiological mechanisms underlying aetiology of the stroke. Ultimately, similar analyses with larger cohorts could lead to a more integrated multimodal model of behavior and brain ana...
