Maximizing communication participation and quality of life and minimizing burden of persons with PPA and their communication partner(s)

What is Primary Progressive Aphasia?

Primary progressive aphasia (PPA) is a clinical dementia syndrome that is caused by neurodegenerative diseases including Alzheimer’s disease or a form of Frontotemporal Lobar Degeneration.  

Below we break down the PPA term to uncover how each word contributes to the definition of the syndrome.


Impairment is prominent in a single domain (language) with relative sparing of other domains early on (e.g., memory, personality and perception)


The impairment will get worse over time, since it is caused by neurodegenerative disease


Refers to the language impairment that individuals experience


What is Communication Bridge?

The goal of the Communication Bridge Research Program is to develop optimal evidence-based strategies to maximize communication participation and quality of life and minimize burden for persons with PPA and related dementias and their communication partner(s).

We aim to achieve this goal by measuring the efficacy and effectiveness of interventions through rigorous clinical trials and related research methods. Our interventions are informed by:

  • Previous research
  • Existing clinical care models
  • Individuals and family members/communication partners impacted by PPA and related dementias
  • Key community members and stakeholder

Can I participate in the Communication Bridge Research Program?

Yes! The Communication Bridge Research Program has multiple opportunities to participate in research. No travel is required; all study visits take place over the Internet in your home. Current research studies are designed for individuals with PPA and their communication partners. We aim to expand these programs in the future.

 Active/Future Research Studies for individuals with PPA and their communication partners include:

  • Communication Bridge 3 Clinical Trial
  • Focus groups, surveys, and other feedback studies that will help to optimize and inform current and future interventions and care.
