Primary Progressive Aphasia (PPA) is a neurodegenerative disorder characterized by progressive loss of language abilities, while other cognitive functions remain relatively preserved for at least two years["@mesulam2001"]. Treatment approaches focus on speech and language therapy, pharmacological interventions, and supportive management strategies.

Speech and Language Therapy
Core Principles
Speech and language therapy forms the cornerstone of PPA management, though it differs from aphasia treatment post-stroke due to the progressive nature of the disorder[@taylor2014].
Key Approaches:
Compensatory Strategies
Gesture and pointing systems
Written and augmentative communication
Communication partner training
Use of technology (speech-generating devices)
Maintenance Therapy
Preserving existing language abilities
Strengthening neural connections through repetitive practice
Errorless learning techniques
Life Participation Approach
Focusing on communication goals relevant to daily activities
Adapting environments to support communication
Training family members and caregivers
Evidence Base
The efficacy of speech therapy in PPA varies by subtype, with semantic variant PPA often showing less response than nonfluent/agrammatic variant[@jokel2019]. Intensive, personalized therapy programs yield better outcomes than standard protocols.
Pharmacological Approaches
Current Status
No FDA-approved medications specifically target PPA. However, several off-label approaches have been investigated[@vandenbulcke2020]:
