ABSTRACT Background Some bilinguals with aphasia tend to mix languages within a single utterance. Two opposing views attribute this to difficulty with either language control or word retrieval. Aims This study investigated the influence of factors that increase activation of the non-target language on the occurrence of language mixing errors. This increased activation predicts more language mixing errors if there is a language control issue, but not if they stem from word retrieval difficulties. Methods and procedures A picture naming experiment was conducted with a bilingual individual with aphasia who showed language mixing. We investigated the influence of four factors likely to influence activation of representations of the non-target language on response accuracy, response latency and the occurrence of language selection errors: language, language mode, task, and phonological overlap between the target word and its translation equivalent. Outcomes and results The increased activation of the non-target language induced by language mode, task and phonological overlap with the translation equivalent did not lead to an increase in language selection errors when compared to correct responses. This is despite the fact that these factors affected accuracy and response latency, in the direction that is expected in unimpaired bilingual performance. Conclusions Results were not consistent with a disruption of the cognitive control needed to respond in the intended language. Instead, they highlight that language mixing in this individual, rather than being “pathological”, is instead used as a strategy to potentially improve communication when lexical retrieval difficulties occur. Language mixing behaviours in aphasia may not be due to issues of control and have a communicative value that should be recognised.

ABSTRACT Background Connected speech assessment is essential to characterize the language features in primary progressive aphasia (PPA). This is especially true for the non-fluent/agrammatic variant (nfvPPA) in which one of the core features is agrammatism. Identification of agrammatism typically involves the analysis of sentence production, as in connected speech, in order to detect syntactic deficits. However, little is known about the longitudinal changes occurring in connected speech of individuals with non-fluent PPA. Aim The aim of this study was to assess changes in connected speech over a one-year span in participants with nfvPPA using semi-structured interviews. Methods and procedures We conducted a prospective group study including participants with nfvPPA (n=9) and age- and education-matched healthy controls (n=9). For each individual, connected speech was obtained using topic-directed interviews at two testing rounds, each approximately one year apart. Production on each task was recorded, transcribed and analyzed according to the Quantitative Production Analysis (QPA) protocol, a tool developed by Berndt and colleagues (2000) for the analysis of sentence production in aphasia. For each group, the probability of deterioration between the two testing rounds was estimated using Bayesian analysis. Results and outcomes For individuals with nfvPPA, statistical evidence of deterioration from the first testing round to the second was found for five variables, namely the proportion of pronouns, the proportion of verbs, the proportion of closed class words, the inflection index and the proportion of well-formed sentences. Conclusions Results from the present study suggest that variables relating to word-finding and morphology are more vulnerable to time and therefore may be relevant potential targets for intervention.

ABSTRACT Background Remotely-supervised transcranial direct current stimulation (RS-tDCS) is a telerehabilitation protocol that provides access to tDCS treatment to participants with aphasia in their homes using real-time monitoring via videoconference and overcomes barriers associated with in-person tDCS treatment of neurological disease. Aims Two feasibility studies for participants with aphasia are presented herein that investigate (1) RS-tDCS procedural implementation, acceptability, and demand, and (2) acceptability of ten repeated consecutive RS-tDCS sessions. Methods & Procedures Thirteen participants with aphasia were enrolled in Study 1: (1) seven participants with stroke-induced latent aphasia, (2) four participants with stroke-induced clinically diagnosed aphasia, and (3) two participants with logopenic variant primary progressive aphasia (lvPPA). Four supervisors (1 certified speech-language pathologist [SLP], 3 graduate SLPs-in-training) were trained to supervise RS-tDCS and also provided survey responses. All participants participated in RS-tDCS training and a virtual simulation of home delivery. Two participants with stroke-induced aphasia (1 latent aphasia, 1 clinically diagnosed aphasia) were enrolled in 10 consecutive sessions of RS-tDCS alongside computerized treatment in their home for Study 2. Outcomes & Results This work provides preliminary evidence for the feasibility of RS-tDCS for people with stable and progressive aphasia of varying severity and typology and includes both participant and clinician perspectives. Importantly, no major barriers to use of RS-tDCS were revealed for people with aphasia, though eHelpers were required for two participants. Conclusions This work confirms that remotely supervised at-home tDCS studies can be used to enable much-needed efficacy trials, with sufficient sample size, power, and dosing considerations, that will determine the clinical efficacy of tDCS as a treatment adjuvant to aphasia treatment.
