Speech & Voice

 Parkinson’s Disease affects the coordination, timing and force characteristics of the muscles used for speech and voice. It is estimated that 75% of individuals with PD experience changes in speech and voice at some point throughout the disease progression. The same physical symptoms that occur in the limbs, such as reduced movement, rigidity and tremor, affect speech.  (Lee Silverman Voice Treatment (LSVT LOUD®,  SPEAK OUT!®, Voice therapy)

Swallowing and Cough

 Just as the muscles of speech and voice are affected by Parkinsonism, the swallowing and cough muscles are also greatly affected by the disease.  In fact, some claim that 100% of people with Parkinson’s disease will develop some sort of dysphagia (swallowing difficulty).  It is essential that dysphagia be properly evaluated and treated because it can result in life threatening consequences like aspiration pneumonia, malnutrition, and/or dehydration.  We now also know that cough can become impaired in people with PD.  Cough and swallowing are closely related and a strong/effective cough is important for keeping food and liquid out of the airway.  (Swallow Therapy,  Expiratory muscle strength training (EMST) it is categorized as respiratory muscle strength training (RMST).

Cognition and Memory

 Speech-language pathologists also evaluate and treat difficulties with language production.  Language difficulties are not as common in Parkinson’s disease, but can occur, particularly with other Parkinsonian disorders.  These may include difficulties thinking of the words you want to use, forming complete sentences, or even difficulties in the comprehension of language.  There are various standardized tests that are given to evaluate language function and Speech-Pathologists also have ways of treating these deficits.
