More than 2.8 million people worldwide are currently living with a multiple sclerosis diagnosis (MS). Those with MS know all too well it is a chronic disease—there is no break—and it is something they grapple with each day, year after year. MS signs and symptoms can vary by the day, and in severity depending on each person’s disease course.

We’ve learned from the community that many people feel there is simply not enough time in the day to keep up with the continually evolving and complex science and information that comes with a diagnosis.  In the last 10 years alone, the scientific understanding of MS has evolved significantly, and so has the way we talk about the disease.

Communicating about MS can be Challenging

New terms can accompany new progress and with rapidly advancing science and the many terms associated with MS, it can be hard to keep up with every new development. As we know, language plays a key role in all parts of our lives, particularly when it comes to issues of understanding and feeling like we are in control of our own lives, and especially when coping with a chronic illness. When someone is living with MS, their words and the way they communicate can make all the difference – especially when many MS experiences are not always as they seem.  

Making Sense of MS

Bruna and Jaime, a couple who live in Brazil and both have MS, have had very different journeys. What they both intimately understand is the powerful role words—and communication—play when it comes to this complex disease. Stories like theirs led us to think about what we could do to help make it easier for people affected by MS to navigate through the different terms and topics that they face every day. We decided to break down the science and help explain what it really means to help the MS community Make Sense of it all.

“When I first came in contact with the words – Multiple Sclerosis (MS), I had a lot to learn. When I looked online I found a lot of misleading information –  which was shocking! That’s why I started my blog. I didn’t want those who were recently diagnosed to find inaccurate information and language that could affect their decision-making about their health, especially when it comes to MS!”

When people are equipped with the words they need to know, they are not only able to better understand the science of how MS is affecting their mind, body and lives, but also how to take control where possible and have meaningful and necessary conversations with their care teams on how new MS terms, concepts and science will impact their future.
