How Evidence-Based Practice (E³BP) Informs Speech-Language Pathology for Primary Progressive Aphasia

Area of Science:

• Neurology
• Speech and Language Pathology

Background:

• Communication impairment in primary progressive aphasia (PPA) requires clinical attention.
• Speech-language pathologists (SLPs) offer vital support, but face underrecognition and low referral rates.

Purpose of the Study:

• To describe how evidence supports SLP interventions for PPA communication difficulties.
• To highlight the application of the Evidence-Based Practice (E³BP) model in PPA management.
• To encourage healthcare professionals to utilize SLP services for individuals with PPA.

Main Methods:

• The study conceptualizes evidence-based practice using the E³BP model.
• It examines evidence across research-based evidence, practice-based evidence, and informed patient preferences.
• The approach focuses on managing communication difficulties in PPA.

Main Results:

• Evidence supporting SLP interventions for PPA exists across all three E³BP components.
• SLP interventions can be both evidence-based and patient-centered.
• Effective interventions can educate, remediate linguistic skills, and increase daily participation.

Conclusions:

• SLP interventions are crucial for ameliorating communication impairment in PPA.
• The E³BP model provides a framework for patient-centered, evidence-based SLP care.
• Increased recognition and utilization of SLP services can significantly enhance the quality of life for individuals with PPA.
