Therapy-Induced Electrophysiological Changes in Primary Progressive Aphasia: A Preliminary Study.

ABSTRACT:

Aims

This preliminary study aimed to investigate therapy-induced electrophysiological changes in persons with primary progressive aphasia (PPA). The investigated event-related potential (ERP) components associated with language processing were the mismatch negativity, P300, N400, and P600.

Methods

A linguistic ERP test battery and standardized language assessment were administered in four patients with PPA of which two received speech-language therapy (SLT) and two did not receive therapy. The battery was administered twice with approximately 6 months in between in each patient. The results of the follow-up assessments were compared to the results of the initial assessments.

Results

Although the results of the behavioral language assessment remained relatively stable
