Neurodegenerative diseases are one of the most common disorders of the central nervous system. They all share the existence of a progressive degeneration of all or part of the nervous system. Their frequency, the severity of their disorders and the disabilities to which they lead make them a major public health problem. Among these pathologies, Parkinson’s disease (PD) is particularly studied in movement disorders, in particular because of its prevalence (in Europe, 150 patients per 100,000 inhabitants, of the order of 140,000 patients in France). While the motor expression of symptoms is reflected mainly in the limbs, the musculature involved in speech production is also subject to characteristic dysfunctions. Speech disorders can therefore be developed by infdividuals suffering from PD or other movement disorders. All speech disorders in PD and movement disorders are grouped under the generic term dysarthria and to date, data regarding the pathophysiology of this disorder remains incomplete.
