About this episode

This episode discusses the evolving understanding of multiple sclerosis progression beyond relapses with physician’s assistant Lisa Fox.

The Puzzle of Progression – Episode 198 Multiple sclerosis (MS) is evolving—and so is the way we understand it. In this episode, host Stephanie Buxhoeveden sits down with physician’s assistant Lisa Fox to unpack one of the most important shifts in MS care: recognizing progression beyond relapses. They explore the concept of PIRA (progression independent of relapse activity), why patients may feel worse even when MRIs look stable, and how new research, biomarkers, and diagnostic tools are changing the conversation. From distinguishing different progressions to navigating the emotional impact of a changing diagnosis, this episode offers clarity, validation, and hope.
