What are the statistics on conversion from RRMS to SPMS in the modern DMT era?

This is a really important question, and the honest answer is that the picture is still evolving. Here's what is currently known:

Without DMT treatment:
- 50% of people with RRMS transition to SPMS within 10 years
- 90% tend to transition within 25 years
- The median transition time is around 19 years without treatment
- The average age at transition is around 40 years old With DMT treatment:

DMTs have clearly changed the landscape, but it's still too early to know exactly how much they delay or prevent the shift to SPMS. What is known is that DMTs can:

- Reduce the frequency of relapses
- Limit new lesion activity on MRI scans
- Slow overall disease progression and disability

The key takeaway is that starting DMTs as early as possible after an RRMS diagnosis gives the best chance of slowing progression. Talking with a neurologist about the most effective DMT option for your specific situation is really the best next step.
