“…Aphasia occurs in about 30% of stroke patients and is characterized by impairments in oral fluency, comprehension, repetition, naming, reading, or writing (1). The processing of language is the core of cognition (2) and requires the participation of other non-linguistic cognitive functions (2)(3)(4)(5). Moreover, the overlapping neural networks of language and nonlinguistic cognition (6) suggested that the language and nonlinguistic cognitive function of patients with post-stroke aphasia (PSA) (3) cannot be separated.…”

“…There is growing consensus that aphasia might be accompanied with deficits of other cognitive functions (2,(7)(8)(9), such as executive function (4,6,10), attention (6,(11)(12)(13), visuospatial perception (14,15), logical thinking (10), and memory (14,16,17), after a left hemispheric stroke. Nonlinguistic cognitive impairments are associated with semantic cognitive deficits (18), comprehension difficulty (5), and other language impairments (4), which also play an important role in aphasia recovery and rehabilitation (19)(20)(21)(22)(23)(24)(25).…”

Background: Non-linguistic cognitive training has been suggested to improve the communication skills of patients with post-stroke aphasia (PSA). However, the association between language and non-linguistic cognitive functions is not fully understood. In this study, we used the Loewenstein Occupational Therapy Cognitive Assessment (LOTCA) to evaluate the characteristics of non-linguistic cognitive impairments in Chinese PSA patients. Methods: A total of 86 stroke patients were recruited in this study. Language and non-linguistic cognitive impairments were evaluated by the Western Aphasia Battery (WAB) and LOTCA, respectively. The patients were divided into two groups (PSA and non-PSA), and the Chinese norm (the data came from 44 Chinese individuals without neurological disorders in a previous study) was used as the control group. The LOTCA scores were compared among the three groups. Patients in the PSA group were subdivided into the fluent aphasia group (FAG) and the non-FAG according to the Chinese aphasia fluency characteristic scale. The LOTCA scores were also compared between the PSA subdivisions. Potential confounders were adjusted in the analysis of covariance. Partial correlation analysis between the subscores of WAB and LOTCA was also performed. Results: The total LOTCA scores in the PSA group (75.11 ± 17.08) were significantly lower compared with scores in the non-PSA (96.80 ± 7.75, P < 0.001) and the control group (97.65 ± 16.24, P < 0.001). The PSA group also had lower orientation, visual perception (VP), spatial perception (SP), visuomotor organization, thinking operation, and attention scores.

“…Some investigators believe that executive functioning and language are mutually related, that is, each skill of one part is dependent on or is related to certain skills on the other side (5). Other researchers have even suggested that a number of language elements, such as comprehension, are robust predictors of EF abilities (10).…”

The Relationship Between Set-Shifting Deficits and Language Difficulties in Persian-Speaking Post-Stroke Patients with Aphasia

et al. 2019

Background: Post-stroke persons with aphasia (PWA) may suffer from deficits in executive function (EF). Cognitive flexibility, as an important element of EF, may be affected by PWA. As a task of cognitive flexibility, set-shifting can be measured by the Wisconsin Card Sorting Test (WCST). Assessing these EF basics may have important implications for cognitive-communicative rehabilitation of PWA. Objectives:The aim of the current study was to examine set-shifting skills and their correlation with language components of Persian-speaking PWA.Methods: Nineteen Persian-speaking, non-fluent PWA (13 males and six females; mean age was 54.26 ± 8.88 years, and age range was 32 to 69 years old) participated in this study. The bedside version of the Persian Western Aphasia Battery (P-WAB-1) and the WCST were performed to assess language and set-shifting abilities, respectively. The Spearman's rank correlation coefficient test was used to examine the correlation between the variables. Statistical analyses were performed using the SPSS 18.0 software. Results: The results showed that the P-WAB-1 score was inversely correlated with perseverative errors index of WCST (r = -0.48, P < 0.05). Also, there was a significant correlation between the "fluency of spontaneous speech" subtest of P-WAB-1 and WCST indices, including number of categories completed (r = 0.54, P < 0.05), total number of correct responses (r = 0.61, P < 0.05), total number of errors (r = -0.60, P < 0.05), and non-perseverative errors (r = -0.44, P < 0.05). Conclusions: Based on these results, it appears that decreased cognitive flexibility of PWA may coincide with decreased language ability. This study broadens current understanding of the complex relationship between language and EF by measuring set-shifting in a sample of non-fluent PWA. These results may be beneficial to cognitive-communicative rehabilitation programs for PWA.

“…Additionally, aphasia following a stroke can be accompanied by deficits in cognitive abilities such as attention, 15 speed of processing, working memory and other executive functions. 16 It has been shown that these cognitive deficits impact recovery and rehabilitation of aphasia. [17][18][19] These cognitive abilities are also known to be involved in sentence comprehension and speech production.…”

Investigating a new tablet-based telerehabilitation app in patients with aphasia: a randomised, controlled, evaluator-blinded, multicentre trial protocol

et al. 2020

View full text Add to dashboard Cite

IntroductionAphasia is a common language disorder acquired after stroke that reduces the quality of life of affected patients. The impairment is frequently accompanied by a deficit in cognitive functions. The state-of-the-art therapy is speech and language therapy but recent findings highlight positive effects of high-frequency therapy. Telerehabilitation has the potential to enable high-frequency therapy for patients at home. This study investigates the effects of high-frequency telerehabilitation speech and language therapy (teleSLT) on language functions in outpatients with aphasia compared with telerehabilitative cognitive training. We hypothesise that patients training with high-frequency teleSLT will show higher improvement in language functions and quality of life compared with patients with high-frequency tele-rehabilitative cognitive training (teleCT).Methods and analysisThis study is a randomised controlled, evaluator-blinded multicentre superiority trial comparing the outcomes following either high-frequency teleSLT or teleCT. A total of 100 outpatients with aphasia will be recruited and assigned in a 1:1 ratio stratified by trial site and severity of impairment to one of two parallel groups. Both groups will train over a period of 4 weeks for 2 hours per day. Patients in the experimental condition will devote 80% of their training time to teleSLT and the remaining 20% (24 min/day) to teleCT, vice versa for patients in the control condition. The primary outcome measure is the understandability of verbal communication on the Amsterdam Nijmegen Everyday Language Test and secondary outcome measures are intelligibility of the verbal communication, impairment of receptive and expressive language functions, confrontation naming. Other outcomes measures are quality of life and acceptance (usability and subjective experience) of the teleSLT system.Ethics and disseminationThis study is approved by the Ethics Committee Bern (ID 2016-01577). Results will be submitted to a peer-reviewed journal.Trial registration numberNCT03228264.
