Speech characteristics of parkinson disease

Abstract

Objective: Parkinson Disease (PD) is known the second most frequent neurodegenerative age-related disorder after Alzheimer’s disease. Although over the six million people worldwide suffer from PD, the main cause of the disease remains are unknown. Speech and language impairments have emerged in most patients with PD during the course of the disease. However, clinical profiles or characteristics that might differentiate individuals with PD who are predisposed to speech and language deficits are generally overlooked. Moreover, factors that expedite language disability have still been remained elusive. It is thought that the awareness of speech and language impairments in PD can significantly help to maintain language abilities as the disease progresses and also may contribute to improving communication skills with patients. For this reason, the present study aims to constitute a comprehensive frame for the speech and language characteristics of individuals with PD
