The concept of a digital twin is revolutionizing medicine, offering a new way to personalize treatments and predict disease progression. But what exactly does it mean for multiple sclerosis patients? In the 100th anniversary episode of the English MS-Perspektive Podcast, Prof. Tjalf Ziemssen, one of the world’s leading MS experts and innovators, explains how AI and big data are shaping the technology of digital twins to improve MS care.
We discuss how this innovative approach differs from traditional monitoring tools, its potential for predicting disease progression, and how it could help neurologists adjust treatments sooner. Beyond medical care, digital twins can also support lifestyle adjustments and rehabilitation strategies. And they can show patients whether they are being well cared for or missing important checkups.
Find out more about the real-world applications, current challenges and future possibilities of digital twin technology for people with MS.

Introduction
Tjalf, what inspired you to develop the concept of a Digital Twin for MS patients? How does it work?
Prof. Tjalf Ziemssen: The idea came from the need to improve the way we monitor and predict MS progression. Traditional methods rely on periodic assessments, which can miss important disease developments between visits. A Digital Twin continuously integrates real-time data from various sources—MRI scans, blood markers, patient-reported symptoms, and even lifestyle factors—to create a dynamic, personalized model of a patient’s disease. This allows for more proactive and tailored treatment adjustments.
How is a Digital Twin different from traditional disease monitoring tools?
Prof. Tjalf Ziemssen: Traditional monitoring often relies on snapshots—data collected at specific moments during medical visits. A Digital Twin, however, provides a continuous, evolving model that reflects how a patient’s MS is progressing in real time. It allows us to simulate different treatment scenarios and predict potential outcomes before making clinical decisions.
Can you explain in simple terms how AI and big data contribute to this concept?
Prof. Tjalf Ziemssen: AI helps by analyzing massive amounts of patient data to identify patterns that may not be obvious through traditional methods. Machine learning algorithms process MRI images, genetic markers, and even wearable device data to refine predictions about disease activity. Big data allows us to compare an individual’s MS progression with thousands of other cases, making predictions more accurate and personalized.
Potential Benefits for MS Patients
Could the Digital Twin be used to predict disease progression and help neurologists adjust treatments earlier?
Prof. Tjalf Ziemssen: Absolutely. By continuously analyzing data, a Digital Twin can detect early signs of worsening disease before clinical symptoms appear. This allows neurologists to make proactive treatment adjustments, potentially slowing disease progression and reducing relapses.
Could it also help in non-medical aspects, like lifestyle adjustments and rehabilitation strategies?
Prof. Tjalf Ziemssen: Yes, that’s a crucial aspect. A Digital Twin can analyze how lifestyle factors—such as sleep, diet, or exercise—affect a patient’s symptoms. If certain activities consistently correlate with fatigue or increased symptoms, patients can make informed adjustments. It also helps optimize rehabilitation strategies by identifying the most effective exercises based on the patient’s specific condition.
Realistic Applications & Current Challenges
How close are we to using Digital Twins in everyday MS care? What challenges still need to be addressed?
Prof. Tjalf Ziemssen: We are making significant progress, but full implementation in everyday clinical practice will take time. One challenge is integrating different data sources into a unified model that is both accurate and user-friendly. Another is regulatory approval—ensuring that these AI-driven insights meet strict medical and ethical standards. Additionally, healthcare systems need to be prepared for a shift toward data-driven, personalized medicine.
How do you see neurologists and patients adopting this tool—will there be skepticism, or do you think they will embrace it?
Prof. Tjalf Ziemssen: A mix of both. Some neurologists may be cautious about relying on AI-driven models, preferring traditional methods. However, as we demonstrate the accuracy and usefulness of Digital Twins, I expect more acceptance. Patients, on the other hand, are generally more open to technology that provides insights into their condition, especially if it empowers them to take more control over their health.
The Future of Digital Twins in MS Treatment
How might Digital Twins contribute to faster and more personalized drug development for MS?
Prof. Tjalf Ziemssen: Drug development often takes years, partly because clinical trials require large groups of patients and long observation periods. Digital Twins could accelerate this process by simulating how new treatments would affect different types of MS patients. This could help identify the most promising therapies faster and reduce the need for large-scale trials.
In five to ten years, how do you envision a neurologist using Digital Twin technology in a routine patient consultation?
Prof. Tjalf Ziemssen: In the future, neurologists will likely have access to an AI-driven dashboard that provides a real-time overview of each patient’s Digital Twin. They’ll be able to see how the disease is progressing, which treatments have been most effective, and receive AI-generated recommendations. This will enable truly personalized treatment decisions, moving beyond the one-size-fits-all approach.
Closing Thoughts & Call to Action
What should MS patients and neurologists expect next when it comes to Digital Twin development?
Prof. Tjalf Ziemssen: Expect continued advancements in AI and data integration, leading to more precise and individualized predictions. As Digital Twins become more refined, we’ll see their role expand beyond MS to other chronic diseases as well.
How can patients and the MS community contribute to making Digital Twin technology a reality?
Prof. Tjalf Ziemssen: By participating in research studies and sharing their health data in secure, ethical frameworks, patients help improve the accuracy of Digital Twins. Advocacy also plays a role—raising awareness about the potential benefits of AI-driven healthcare can encourage faster adoption.
Where can interested listeners follow your research or get involved?
Prof. Tjalf Ziemssen: You can follow my work through academic publications, MS research platforms, and social media channels. We also encourage those interested to engage with patient organizations that support digital health initiatives.
