This observational study aims to better understand and tell apart two different kinds of Progressive Apraxia of Speech (AOS). AOS is a problem with planning speech that gets worse over time. Researchers want to see if these different types of AOS can be identified through brain imaging and other tests. To join, you must be over 18, speak English, and have a progressive speech problem that a speech-language pathologist has identified as AOS. You will have a neurological exam, speech and language assessments, memory and thinking tests, an MRI brain scan, and a DaTscan. The study hopes to distinguish these AOS types within 1-2 years after your initial imaging. The current recruitment status is unclear.

You would see a neurologist, a speech pathologist, and a study coordinator for various tests. You would also undergo an MRI brain scan and a DaTscan.

Compensation

Not stated in the trial record.

Follow-up

The primary goal is measured 1-2 years after baseline imaging, suggesting a follow-up period.
