“…However, some authors have subsumed it under anomic aphasia [18][19][20], indirectly acknowledging that language abilities in people with latent aphasia are somewhat mildly impaired. Furthermore, recent evidence suggests that despite the within-normal-limits performance in the aphasia test, communication difficulties are reported by such individuals [21]. Similar to other researchers [16], in this study, we define latent aphasia as a diagnostic entity above the cut-off point of the West-ern Aphasia Battery [7].…”

Sentence Recall in Latent and Anomic Aphasia: An Exploratory Study of Semantics and Syntax

We investigated whether semantic plausibility and syntactic complexity affect immediate sentence recall in people with latent and anomic aphasia. To date, these factors have not been explored in these types of aphasia. As with previous studies of sentence recall, we measured accuracy of verbatim recall and uniquely real-time speech measures. The results showed that accuracy did not distinguish performance between latent aphasia and neurotypical controls. However, some of the real-time speech measures distinguished performance between people with latent aphasia and neurotypical controls. There was some evidence, though not pervasive, that semantic plausibility and syntactic complexity influenced recall performance. There were no interactions between semantic plausibility and syntactic complexity. The speed of preparation of responses was slower in latent aphasia than controls; it was also slower in anomic aphasia than both latent and control groups. It appears that processing speed as indexed by temporal speech measures may be differentially compromised in latent and anomic aphasia. However, semantic plausibility and syntactic complexity did not show clear patterns of performance among the groups. Notwithstanding the absence of interactions, we advance an explanation based on conceptual short-term memory as to why semantically implausible sentences are typically more erroneous and possibly also slower in recall.

“…Other synonymous diagnostic labels include subliminal aphasia (Boller, 1968), people who have become nonaphasic (Neto & Santos, 2012), not aphasic by WAB [Western Aphasia Battery] (Dalton & Richardson, 2015;Fromm et al, 2017), and very mild aphasia (Cavanaugh & Haley, 2020). The term latent aphasia was coined by Pichot (1955) in the context of people affected by atherosclerosis, although other researchers described similar conditions earlier according to Boller and Vignolo (1968).…”

Purpose: The purpose of this study was to improve our understanding as to which factors determine online, spoken sentence production abilities of adults with latent aphasia in a discourse context. Method: Discourse samples of the story of Cinderella elicited from AphasiaBank were analyzed with speech analysis software. Participants comprised people with latent and anomic aphasia as well as neurotypical controls (10 per group). Durations of pauses (silent and filled) were analyzed according to (a) the location they occurred (between or within sentences), (b) the syntactic complexity of sentences (simple, complex), and (c) sentence length (number of words). Statistical comparisons were conducted using mixed-effect models. Results: The two clinical groups (latent and anomic) differed from controls in the duration of pauses, both between and within sentences. Syntactic complexity did not exert an effect on either of the two clinical groups as compared with controls. As compared with controls, both clinical groups paused more before long in comparison with short sentences. Conclusion: Reduction in processing speed, which affects the ability to simultaneously maintain multiple linguistic and other cognitive demands associated with planning and monitoring of utterances, is a major factor that compromises sentence production in spoken discourse in latent aphasia.

“…In addition to the careful use of the suggested cutoff criterion scores, clinicians are encouraged to supplement their test interpretation with qualitative observations of their patients' responses. Persons with aphasia exhibit unique behaviours that are not typically observed in neurotypical bilinguals and could help inform differentiating between mild cases of aphasia and low proficiency bilingual behaviours (Armstrong et al 2013;Cavanaugh & Haley, 2020). These include linguistic limitations such as frequent rephrasing, slow rate of speech, filled pauses, prolonged time response, word-finding strategies and paraphasia in order to reliably identify individuals with mild aphasia.…”

Background: The use of standardized tests specifically designed for and normed on bilingual groups is crucial for the accurate diagnosis and language profiling of bilingual speakers with aphasia. Currently, there is a dearth of norms and supporting psychometric data for the few available bilingual aphasia assessments. The only available aphasia test for Korean-English (KE) bilinguals is the Korean-English Bilingual Aphasia Test (KE-BAT). The absence of bilingual normative data for the KE-BAT limits its clinical and research utility. Aims:(1) To revise the original screening KE-BAT to clarify ambiguities in its instructions and stimuli; and (2) to examine subtest and item performance across the two languages for the revised screening KE-BAT with a local sample of highly proficient KE bilinguals. Methods & Procedures:The original screening KE-BAT was first revised to replace unrecognizable drawings, address ambiguities in the instructions and stimuli, and increase the number of items on naming subtests. This revised test is henceforth referred to as the adapted screening KE-BAT (AS KE-BAT). A total of 21 neurologically healthy, highly proficient and college-educated KE bilinguals (19-34 years old) were recruited from a large city in the United States. Participants completed three measures of language proficiency and the AS KE-BAT including the KE translation test (Part C). Total and subtest scores were compared across the two languages, and individual item accuracy was calculated. Incorrect responses of low scoring items were examined.Outcomes & Results: Performance was comparable across Korean and English for all subtests, except for the spontaneous speech subtest. The item accuracy of 17 items (7% of total items) in the AS KE-BAT fell to < 80%, and four items (1.6% of total items) had an accuracy < 60%. Incorrect responses of low scoring items were caused by phoneme misperception, lexical substitution and morphosyntactic L2 patterns. Conclusions & Implications:The results of the study highlight the importance of empirically examining the performance of neurotypical bilinguals on bilingual aphasia assessments to establish their psychometric properties. Based on the small-sized local bilingual normative sample obtained in this study, appropriate cut-off criteria, recommendations for clinical interpretation and further modifications of the AS KE-BAT are proposed.
