If you Google the term "shared decision making", you'll find it defined as a collaborative process where patients and clinicians work together to select tests, treatments, and care plans based on clinical evidence and the patient's personal values and goals. But shared decision-making isn't an automatic happy pill. It takes work, it takes discipline, and it takes a clear understanding of both the patient's and the clinician's roles. This week, Dr. Aliza Ben-Zacharia and Linda Lachman join me to share how shared decision-making has worked for them over the course of their longtime...

We get more listener emails about diet and MS than almost any other topic. If you're curious about how some of the well-known diets for MS actually stack up, or you're interested in understanding the connection between diet and MS-related fatigue, or you want to know what the biggest obstacle to staying on a new diet is (and this may surprise you), then this is the episode for you. We're devoting this week's entire episode to my conversation with Dr. Tyler Titcomb, an assistant professor in the Department of Dietetics and Nutrition, and a registered dietitian with a PhD in Nutritional...

During his fellowship in the United States, Dr. Avinash Chandra trained to become an MS specialist at a world-class MS center. Then he returned home to Nepal and discovered that MS was largely considered non-existent. But Dr. Chandra knew it wasn't. In this week's episode, Dr. Chandra discusses his experience creating a framework for MS care in Nepal that hadn't existed before. He also explains the necessary trade-offs in providing costly medical treatment in a country where the average family of four lives on an income of $500 a month. It's been well-established that males...

If you’ve spent any time at all living with or caring for someone with multiple sclerosis, you know that medical textbooks and information-filled websites can give us facts, figures, and symptoms, but they rarely capture the sometimes messy, sometimes overwhelming, and sometimes darkly funny reality of what it actually feels like to get a diagnosis of MS and realize your life has suddenly shifted under your feet. Our guest, Liat Shalom, was diagnosed with MS in 2021, at the age of 30. Instead of letting that diagnosis define her, Liat picked up her pen and created Unravelled—a...

Living with depression has been described as "like living under a wet, heavy blanket". It can stop someone from showing up at work, meeting up with friends, and even connecting with their family. One out of every two people living with MS will experience depression at some point in their MS journey. The METS for MS study is focused on a novel approach to treating major depressive disorder among people with MS -- one that doesn't require another infusion, injection, or pill. This week, Dr. Robert Motl, principal investigator for the METS for MS study, joins us to explain what the study...

The Americans with Disabilities Act ensures that people living with disabilities receive reasonable accommodations at work. That law also applies to students attending most colleges and universities. And the ADA doesn't limit itself to physical disabilities. It's often applied to invisible disabilities, as well. This week, Britt Neff, the Access Specialist at the University of Washington School of Law, joins me to explain all the ways the accommodation process can work for college students living with MS. We'll also tell you about PTD802, an oral remyelination therapy that's just...

A short while ago, we shared very positive results from the Phase 3 clinical trials for fenebrutinib in both relapsing-remitting and primary progressive MS. Those results have been submitted to the FDA for approval. This week, Dr. Jiwon Oh, the principal investigator in one of the Phase 3 trials for fenebrutinib, walks us through these positive results and explains what makes fenebrutinib a different kind of disease-modifying therapy and who might benefit most from it. We're also talking about the European approval of Cenrifki (Tolebrutinib) to treat nonrelapsing secondary...

Next week, Matt Knaggs and Colin Goodman will attempt to set a Guinness World Record for running the 350-mile length of Ireland with MS. This week, you'll meet Matt and Colin and learn why this undertaking is so important to each of them. We're also sharing survey results that point to gaps in how we approach MS care from the day of diagnosis. We'll tell you what it really means when you read that the prevalence of MS is increasing. It isn't bad news at all! We'll provide you with all the details you need to register for ECTRIMS Patient Community Day. And, if you can spare 20 minutes,...

For years, the standard medical advice for someone diagnosed with multiple sclerosis was simple, cautious, and as we now know, incredibly limiting: “Take it easy. Don't overexert yourself. And get plenty of rest.” Today, like almost every other aspect of MS care, neurological rehabilitation is being entirely rewritten. It’s no longer about just managing decline; it’s about leveraging emerging technologies to proactively build resilience, retrain the brain, and adopt cutting-edge exercise science to fundamentally change the trajectory of life with MS. This week, three experts...

This week, our coverage of the Consortium of MS Centers annual meeting continues with my guest, Dr. Stephen Krieger. In a wide-ranging conversation, Dr. Krieger offers a very encouraging clinical trial update, shares his thoughts on what treating someone living with advanced MS ought to look like, and points out potential obstacles to implementing the updated criteria for diagnosing MS. Dr. Krieger is a Professor of Neurology at the Icahn School of Medicine at Mount Sinai in New York, and a Multiple Sclerosis Specialist at the Corinne Coldsmith Dickinson Center for MS. We're also...

We're also talking about the European approval of Cenrifki (Tolebrutinib) to treat nonrelapsing secondary progressive MS, and we'll share our perspective on why the FDA should have -- and should still -- approve this DMT in the U.S.
We'll tell you about two studies funded by the National MS Society that will focus on identifying links between menopause and MS.
We'll share some sobering news about healthcare affordability in America.
And we'll share some good news from the U.S. House Appropriations Committee, along with an opportunity for you to spend just 5 minutes doing some important advocacy work.
We have a lot to talk about! Are you ready for RealTalk MS??!
