Dysarthria in Parkinson's disease : how to understand its physiopathology
'Dysarthria is a generic term that refers to a motor speech disorder, whose origin is a lesion of of the central and/or peripheral nervous system. The hypokinetic dysarthria, frequently present in Parkinson's disease, is characterized by a monotony of intensity and pitch, a decrease of speech stress, a variable speed and a possible inaccuracy of phonemes. This symptom can affect voice quality, speech intelligibility and the prosody, so that many patients complain of speech disorders disrupting their communication competence in everyday life. The perceptual and instrumental assessments of speech, as well as functional neuroimaging studies, allow us to better understand the pathophysiology of dysarthria and to adapt treatments, which variable effects on speech makes it hard to expect beneficial modulations.'
