Speech and Language Deficits of Parkinson’s Disease
Speech and Language Deficits of Parkinson’s Disease
This chapter finds that Parkinson’s disease (PD) patients lack the ability to comprehend and use appropriate language when performing a task or engaging in conversations, and are unable to use the appropriate language needed to perform daily activities. These patients are also observed to forget or use constructive words, sentences, and language required to engage in conversations, and are unable to express, assert, and direct others when interacting or conversing with others. PD patients are unable to use those components of speech that are required to perform a task, and find it difficult to produce and comprehend speech acts. The speech act theory has been used to investigate this deformity in PD patients, revealing that they demonstrate significant language processing impairments.
