“…In the latter case, language difficulty is the most prominent deficit at symptom onset (Gorno-Tempini et al, 2011). Word-finding problems, while also found in the healthy aging population (Burke & Shafto, 2004;Mortensen, Meyer, & Humphreys, 2006;Vogel-Eyny, Galletta, Gitterman, & Obler, 2016), seem to be among the earliest and most pervasive symptoms in these types of dementia, in AD both in earlier (Chen, Ratcliff, Belle, Cauley, DeKosky, & Ganguli, 2001;Mickes et al, 2007;Nicholas, Obler, Au, & Albert, 1996) and later stages (Locascio, Growdon, & Corkin, 1995;Salmon, Heindel, & Lange, 1999), and in all subtypes of PPA, but most prominently in the semantic and logopenic subtypes (Gorno-Tempini et al, 2011;Grossman & Ash, 2004;Hilger, Ramsberger, Gilley, Menn, & Kong, 2014;Kempler & Goral, 2008;Wilson et al, 2010). Two recent review articles, one on AD (Kavé & Goral, 2017) and one on several neurodegenerative disorders including AD and PPA (Boschi, Catricalà, Consonni, Chesi, Moro, & Cappa, 2017), show that word retrieval problems are evident both in single word production and in connected speech in these groups, and point to the importance of using different cognitive and linguistic tasks in the assessment of persons with dementia.…”

In this article, we explore the naming skills of a bilingual English-Norwegian speaker diagnosed with Primary Progressive Aphasia, in each of his languages across three different speech contexts: confrontation naming, semi-spontaneous narrative (picture description), and conversation, and at two points in time: 12 and 30 months post diagnosis, respectively. The results are discussed in light of two main theories of lexical retrieval in healthy, elderly speakers: the Transmission Deficit Hypothesis and the Inhibitory Deficit Theory. Our data show that, consistent with the participant's premorbid use of and proficiency in the two languages, his performance in his L2 is lower than in his L1, but this difference diminishes as the disease progresses. This is the case across the three speech contexts; however, the difference is smaller in the narrative task, where his performance is very low in both languages already at the first measurement point. Despite his word finding problems, he is able to take active part in conversation, particularly in his L1 and more so at the first measurement point. In addition to the task effect, we find effects of word class, frequency, and cognateness on his naming skills. His performance seems to support the Transmission Deficit Hypothesis. By combining different tools and methods of analysis, we get a more comprehensive picture of the impact of the dementia on the speaker's languages from an intra-individual as well as an inter-individual perspective, which may be useful in research as well as in clinical practice.

“…Nevertheless, the Span-MCA results would still allow more informed planning of language remediation and directions of setting functional communication goals (Kong, 2009). A full scale and systematic examination involving more PWA is underway to provide further details of the validity of Span-MCA; this final product of content-based analysis will enable clinicians to expand their current scope of spoken discourse examinations that typically address the degree of grammar and syntax accuracy (e.g., Kong & Law, 2009) or phonemic problems (e.g., Hilger et al, 2014) of output.…”

Aphasia is an acquired language impairment caused by damage in the regions of the brain that support language. The Main Concept Analysis (MCA; Kong, 2016b) is a published formal assessment battery that allows the quantification of the presence, accuracy, completeness, and efficiency of content in spoken discourse produced by persons with aphasia (PWA). It utilizes a sequential picture description task (with four sets of pictures) for language sample elicitation. The MCA results can also be used clinically for targeting appropriate interventions of aphasic output. The purpose of this research is to develop a Spanish adaptation of the MCA (i.e., Span-MCA) by establishing normative data based on native unimpaired speakers of Spanish from four different dialect origins (Central American Caribbean, Andean-Pacific, Mexican, and Central-Southern Peninsular regions). A total of 91 unimpaired participants that consisted of different age groups, education levels, and dialect origins were recruited to establish four sets of dialect-specific norms and scoring criteria of Span-MCA, including target main concepts and corresponding lexical items related to the picture sets. The Span-MCA was also applied to one pilot native Spanish PWA. The normative data suggested that speakers who were younger or with a higher level of education levels produced significantly more accurate and complete main concepts in their spoken discourse. The application of Span-MCA to the pilot native Spanish PWA successfully identified impaired performance, as compared to the dialectally-sensitive norms established in this study. This study highlighted the clinical value of Span-MCA as a supplement to evaluate spoken discourse and target intervention by speech-language pathologists and related healthcare practitioners.

“…The present study can offer more evidence in supporting the needed psychometric properties of spoken discourse outcomes. Similar to other clinically-oriented discourse analyses for PWA [e.g., [20][21][22][23][24], it may be possible to use this proposed method to conduct post-sentential testing in a more informal manner which will bring several benefits from a clinical perspective. Apart from playing a supplementary role to traditional formal aphasia batteries that do not adequately address discourse productions, this method can improve efficiency of discourse assessment and its subsequent analysis would contribute to testing accuracy and minimize fatigue on the part of PWA.…”

Purpose: Aphasia is an acquired language disorder, most commonly caused by a stroke, that adversely affects one’s ability to understand, speak, read, and write. Diagnosis of aphasia is typically done through administration of standardized aphasia batteries, many of which lack a detailed and adequate evaluation of spoken discourse. The aim of this paper was to propose a quick, objective, and comprehensive analytic system that addressed the micro- and macro-linguistic aspects of oral narratives in persons with aphasia (PWA).Methods: Using a subgroup of unimpaired native speakers of English from the public corpus of AphasiaBank, task-specific normative data of three narrative tasks were constructed. Scoring criteria on the production of events, use of corresponding lexical items in these events, and the order of sequence of presenting the events were also developed. Twelve PWA were recruited and their spoken discourse was quantified using this newly proposed analytic system.Results: Significant correlations were found between PWA’s performance on formal aphasia batteries and selected indices on the number of events produced as well as informative words used. Fluent and non-fluent PWA performed significantly differently in terms of their use of informative words and event sequence. The analytic system also demonstrated excellent intra- and inter-rater reliabilities.Conclusions: The clinical feasibility and diagnostic values of this proposed approach to quantify PWA’s spoken output are confirmed. The present investigation also offered more evidence in supporting the needed psychometric properties of spoken discourse analysis that can supplement traditional formal aphasia batteries.
