We read with great interest the recent study by Garcia et al., which showed differing patterns of dysarthria in Parkinson's disease (PD) subgroups with and without mild cognitive impairment (PD-MCI and PD-nMCI, respectively) across two speaking tasks with low (reading) and high (retelling) processing demands. To complement the data and overcome some of the noted limitations such as a requirement for replication, missing within-group comparisons to assess direct contrasts between speaking tasks, unavailable measure of intensity, and potential confounding effect of dopaminergic medication, we investigated the effect of cognitive impairment on motor speech performance in de-novo, drug-naive PD with a similar study design.
