Episode 469: Maintaining and Even Improving Cognitive Function If You're Living with MS with Dr. Anna Kratz
Key Takeaways
- A newly proposed framework by the International Advisory Committee on Clinical Trials in Multiple Sclerosis aims to replace outdated clinical categories with a dynamic, biologically informed profile to guide precision medicine.
- A major international study revealed that finding even a single silent lesion on an annual MRI can increase future relapse and disability progression risks, challenging the concept of tolerable minimal disease activity.
- Researchers have identified advanced MRI markers—specifically paramagnetic rim lesions and choroid plexus volume—that can predict future cognitive decline in early relapsing-remitting MS independent of physical relapses.
- Dr. Anna Kratz explains that cognitive challenges in MS often affect processing speed, memory, and executive function, and that daily ups and downs are frequently influenced by sleep, pain, and fatigue.
- Using real-time smartphone-based testing, Dr. Kratz's research captures day-to-day cognitive fluctuations in a person's lived environment, providing a more comprehensive snapshot than a single in-clinic assessment.
Cognitive changes in MS—fluctuations in processing speed, memory, and executive function—can significantly impact daily life, yet they're often misunderstood or overlooked in routine clinical exams. This week, we are joined by Dr. Anna Kratz, clinical psychologist and Professor in the Department of Physical Medicine and Rehabilitation at the University of Michigan, to discuss actionable, evidence-based ways to navigate cognitive challenges.

Dr. Kratz breaks down the latest findings from the CogDetect-MS study, exploring how daily symptom fluctuations, complex medication regimens, and common substances like caffeine and cannabis influence brain fog. She also shares practical compensatory workarounds and introduces a no-cost digital self-management resource, My MSToolKit.
We'll also explain the new framework for describing MS that's been proposed by the International Advisory Committee on Clinical Trials in Multiple Sclerosis.
We're sharing study results that reveal why detecting even a single silent lesion on an MRI should trigger an immediate conversation about stepping up to high-efficacy therapy.
And we'll tell you about 2 advanced MRI markers that can predict future cognitive decline — even in the absence of any relapses or new lesions on MRI.
We have a lot to talk about! Are you ready for RealTalk MS??!

Frequently Asked Questions
What is the CogDetect-MS study?
The CogDetect-MS study, led by Dr. Anna Kratz, explores actionable and evidence-based ways to navigate cognitive challenges in multiple sclerosis using real-time smartphone assessments.
What are paramagnetic rim lesions in MS?
Paramagnetic rim lesions are active brain MRI borders where inflammation continually simmers around old lesions, slowly expanding and damaging myelin even in the absence of new physical relapses.
Why is a silent lesion on an MRI important?
Even a single silent lesion—a new lesion appearing without symptoms or relapses—is linked to a significantly higher risk of future relapses and disability progression, suggesting a potential need to escalate disease-modifying therapy.
How do daily fluctuations affect MS cognitive testing?
Cognitive function in MS can fluctuate based on factors like sleep quality, pain, and stress, meaning a single, one-time test in a doctor's office may not reflect a patient's true day-to-day abilities.
