PPA is diagnosed when three criteria are met:

  1. There is a gradual impairment of language (not just speech).
  2. The language problem is initially the only impairment.
  3. The underlying cause is a neurodegenerative disease.

Experts further subdivide PPA into three clinical subtypes based on the specific language skills that are most affected.

PPA Diagnostic Checklist

Not all physicians know about FTD, so it is often misdiagnosed or not diagnosed at all. AFTD developed a checklist to help identify red flags for behavioral variant FTD (bvFTD) that you can bring to your doctor. You can download the checklist and indicate which symptoms you or your loved one is experiencing on the front side of the document. The back of the document is designed to help your physician better understand FTD diagnostic criteria.

AFTD is pleased to also share our PPA Diagnostic Checklist in Dutch, French, Italian, Polish, and Spanish. These translated documents have been made possible with the generous support of AviadoBio.
