Can speech therapy slow language loss in progressive aphasia?

This study tests whether specialized speech and language therapy can help 60 adults with primary progressive aphasia (PPA) — a brain disease that slowly destroys the ability to speak and understand language. Participants receive therapy targeting word retrieval and speech production, and are followed for one year to see if communication improves or declines more slowly compared to untreated patients. The goal is to find effective treatments for a condition that currently has no medication.
