“…76 papers studying discourse in patients with FTD were included in the final review. 57 of these papers (75% of all papers) studied English-speaking patients, the remaining 19 papers studied patients speaking Spanish (Baque et al, 2022; Matias-Guiu et al, 2020, 2022), Czech (Daoudi et al, 2022; Rusz et al, 2015; Skrabal et al, 2020), Italian (Catricala et al, 2019; Silveri et al, 2014), French (Bouvier et al, 2021; Macoir et al, 2021), German (Hohlbaum et al, 2018; Staiger A., 2017), Dutch (Bruffaerts et al, 2022), Greek (Karpathiou & Kambanaros, 2022; Koukoulioti et al, 2018, 2020; Potagas et al, 2022), Hindi (Sachin et al, 2008), and Korean (Suh et al, 2010) (Figure 2a). Figure 2b shows the geographical representation of the published papers, with a paucity of languages from South America, Asia, and Africa.…”

Frontotemporal dementia (FTD) is a neurodegenerative disease spectrum with an urgent need for reliable biomarkers for early diagnosis and monitoring. Speech and language changes occur in the early stages of FTD and offer a potential non-invasive, early, and accessible diagnostic tool. The use of speech and language markers in this disease spectrum is limited by the fact that most studies investigate English-speaking patients. This systematic review examines the literature on psychoacoustic and linguistic features of speech that occur across the FTD spectrum across as many different languages as possible. 76 papers were identified that investigate psychoacoustic and linguistic markers in discursive speech. 75% of these papers studied English-speaking patients. The most generalisable features found across different languages, are speech rate, articulation rate, pause frequency, total pause duration, noun: verb ratio, and total number of nouns. While there are clear interlinguistic differences across patient groups, the results show promise for implementation of cross-linguistic markers of speech and language across the FTD spectrum, particularly for psychoacoustic features.

“…One study (Dragoy and Bastiaanse, 2013) did not detail the effect of time, and no study found that present was the most impaired tense. However, 8 studies (Faroqi-Shah and Thompson, 2004;Burchert et al, 2005;Lee et al, 2008Lee et al, , 2013Bos and Bastiaanse, 2014;Faroqi-Shah and Friedman, 2015;Fyndanis et al, 2018a;Koukoulioti et al, 2020) found no difference between tenses (3 explored the three tenses, 4 explored past and present, and 1 study explored past and future). Two studies (Faroqi-Shah and Thompson, 2007;Bastiaanse et al, 2011) had mixed results depending on the language assessed or the task used.…”

Time reference is used to build the temporal framework of discourse and is essential in ensuring efficient communication. Several studies have reported time reference deficits in fluent and non-fluent aphasia and have shown that tenses (past, present, future) are not all impaired to the same extent. However, there is little consensus on the dissociations between tenses, and the question of the influence of the type of aphasia (fluent vs. non-fluent) on time reference remains open. Therefore, a systematic review and an individual participant data meta-analysis (or mega-analysis) were conducted to determine (1) whether one tense is more impaired than another in fluent and non-fluent aphasia and, if so, (2) which task and speaker-related factors moderate tense effects. The systematic review resulted in 35 studies reporting the performance in time reference of 392 participants. The mega-analysis was then performed on 23 studies for a total of 232 participants and showed an alteration of past tense compared to present and future tenses in both types of aphasia. The analysis also showed a task and an age effect on time reference but no gender effect, independently of tenses. These results add to our knowledge of time reference in aphasia and have implications for future therapies.

“…Light verb have been studied most often in relation to semantic dementia (SD) (Kavé et al., 2007; Koukoulioti et al., 2019; Marcotte et al., 2014; Méligne et al., 2011; Meteyard et al., 2014; Meteyard & Patterson, 2009) and dementia of the Alzheimer's type (DAT) (Kim & Thompson, 2004). Semantic dementia, also known as the semantic variant of primary progressive aphasia (svPPA), is a progressive neurological disorder often characterized by the slow loss of semantic knowledge and words (Olney et al., 2017).…”

Light verb production in healthy ageing and dementia

Background Light verbs are highly frequent and semantically impoverished words. It is currently not known whether light verb production in discourse tasks differs by age or for people with dementia of the Alzheimer's type (DAT). Aims The purpose of the current study was two‐fold: (1) to determine whether there is a relationship between age and the proportion of light verbs produce during a narrative discourse task; and (2) to determine whether people with DAT produce a different proportion of light verbs compared with neurotypical adults. Methods & Procedures A total of 469 neurotypical adults and 12 participants with DAT produced narratives from a wordless picture book. Outcome & Results The results indicated that light verb production increases as a function of age, even when controlling for education, and people with DAT produced a higher light verb–word ratio compared with neurotypical adults when matched for age and education. Conclusion & Implication Light verb use may increase as a function of age due to declines in retrieval ability. These declines are not only more pronounced in people with DAT, but also semantic knowledge deficits may contribute to a reliance on light verbs. What this paper adds Light verbs are typically some of the first verbs learned due to their simple semantic construction and high frequency. However, two things are unknown: (1) how light verbs changed across the adult lifespan; and (2) whether cognitive impairment changes light verb production. The study found that light verb production increases as a function of age, and that people with DAT used a higher ratio of light verbs to words in a narrative task compared with neurotypical adults. However, despite the findings, more research is needed to determine their clinical utility. Future research may wish to investigate whether light verbs (1) facilitate comprehension in older adults or (2) may be used in cognitive–linguistic assessments for cognitive impairments.
