Communication impairments in people with progressive supranuclear palsy: A tutorial

Area of Science:

• Neurology
• Speech and Language Pathology

Background:

• Progressive supranuclear palsy (PSP) is a neurodegenerative disease characterized by motor, cognitive, and communication deficits.
• Communication impairments, including motor speech and language disorders, are early and prominent in PSP, yet under-researched.
• The role of speech-language pathologists (SLPs) in managing PSP-related communication issues requires further definition.

Purpose of the Study:

• To delineate the communication impairments observed in individuals with PSP.
• To establish clinical guidelines for SLPs in assessing motor speech and language deficits in PSP.
• To present evidence-based facilitation and compensation strategies for PSP communication management.

Main Methods:

• This tutorial synthesizes current literature on PSP communication impairments.
• It provides a framework for comprehensive assessment by SLPs.
• It outlines therapeutic approaches focusing on functional communication and quality of life.

Main Results:

• Mixed dysarthria is the primary motor speech disorder in PSP.
• There is a lack of consensus regarding the classification of language impairments in PSP.
• Early and ongoing SLP involvement is vital for effective management.

Conclusions:

• SLPs are essential members of the multidisciplinary team for PSP care.
• Early, collaborative intervention focusing on communication facilitates patient and family well-being.
• Further research is needed to clarify language impairments and optimize treatment protocols in PSP.
