Progressive apraxia of speech in Quebec French speakers: A case series.

CONCLUSIONS & IMPLICATIONS: This study provides an in-depth analysis of motor speech characteristics of PAOS in Quebec French speakers and adds further evidence for the differentiation of PPAOS and DAOS. Combining simple perceptual and acoustic analyses represent a promising approach to distinguish the two variants and identify treatment targets. What this paper adds What is already known on this subject Progressive apraxia of speech (PAOS) is a neurodegenerative syndrome characterized by progressive and initially isolated or dominant apraxia of speech (primary progressive apraxia of speech [PPAOS] and dominant progressive apraxia of speech [DAOS], respectively). Studies mostly report articulatory and prosodic deficits in PAOS, but concomitant deficits such as dysarthria and executive dysfunction are also reported. The description of motor speech skills in PAOS remains vague and English-oriented. Studies suggest that speakers presenting with isolated PAOS vs dominant PAOS with concomitant aphasia should be differentiated, but distinct characteristics of the two presentations are unclear. What this study adds to existing knowledge To the best of the authors' knowledge, this study is the first to report transversal data of Quebec-French participants with PPAOS and DAOS. Moreover, this study is a first step towards identifying potential characteristics that could facilitate the diagnosis of PPAOS and DAOS in Quebec French. It makes a significant contribution to our understan...
