Episode 471: Navigating an MS Relapse with Dr. F. Gabriela Karolidis
Key Takeaways
- Dr. F. Gabriela Karolidis joined the podcast to provide a deep dive into understanding, managing, and navigating MS relapses.
- The latest update to the Multiple Sclerosis International Federation's Atlas of MS reveals that global MS prevalence has officially surpassed 3 million people.
- Wearable activity trackers offer valuable real-world mobility data that complements brief, in-clinic patient evaluations by capturing daily activity fluctuations.
- A systematic review of vitamin D supplementation in adults with MS indicates mixed results and does not currently support high-dose vitamin D as a standalone treatment or replacement for disease-modifying therapies.
- A Danish nationwide study found that while high-efficacy disease-modifying therapies effectively reduce relapse rates, their impact on progression independent of relapse activity (PIRA) requires further exploration.
- A new study reveals that adverse social and socioeconomic factors are consistently tied to poorer cognitive outcomes in people living with MS, with a disproportionate burden on non-white individuals.

The MS International Federation has just updated the Atlas of MS, showing more than 3 million people living with MS worldwide. We're sharing the details behind the new numbers.
We'll also share a study showing how wearable activity trackers add a dimension of real-world data that provides a more complete picture of an individual's mobility throughout the day.
We'll tell you about research on Vitamin D supplements that fails to determine whether they are beneficial for people living with MS.
We're sharing study results showing that social and socioeconomic factors clearly affect cognitive function among people living with MS.
We're also sharing results from a nationwide study in Denmark that focused on whether high-efficacy DMTs affect progression independent of relapse activity (PIRA).
And we'll tell you about a fall prevention study that you may be eligible to participate in (compensation provided!).
We have a lot to talk about! Are you ready for RealTalk MS??!

Frequently Asked Questions
What is an MS relapse?
An MS relapse occurs when the immune system mistakenly attacks myelin, the protective layer around nerve fibers in the central nervous system, disrupting signal transmission and causing new or worsening neurological symptoms.
What is a pseudo-relapse?
A pseudo-relapse is a temporary worsening of existing MS symptoms caused by triggers like heat, stress, or infections, rather than new inflammatory activity or demyelination in the central nervous system.
How many people currently live with MS worldwide?
According to the 2024 update of the Multiple Sclerosis International Federation Atlas of MS, the global prevalence of multiple sclerosis has officially surpassed 3 million, with an estimated 3.1 million people living with the condition.
Do wearable activity trackers help manage MS mobility?
Yes, continuous step count data from wearable activity trackers helps fill out a more complete picture of an individual's mobility by capturing how symptoms fluctuate throughout the day outside of the clinic.
