What Multiple Sclerosis Is and How It Affects People

On Accessible Community’s A ‘Day in the Life’ podcast, we have been talking about multiple sclerosis. This post explains what Multiple Sclerosis (MS) is and why inclusion matters. MS is part of human diversity. It affects how people manage their energy, get around, take in information, and connect with others.

What Multiple Sclerosis Is

Multiple sclerosis is a long-term condition that affects the brain and nervous system. In MS, the body’s immune system attacks a coating around nerve fibers called myelin. This coating helps messages travel between the brain and the rest of the body. When it is damaged, those messages slow down or get blocked. MS can look like:

  • Flare-ups, where symptoms get worse, then improve
  • Symptoms that slowly get worse over time
  • A wide range of symptoms that are different for every person
  • Symptoms that are invisible but very real

There are a few types of MS. Relapsing-remitting MS (RRMS) is the most common. Symptoms flare up, then get better. Primary progressive MS (PPMS) gets worse slowly from the start with no clear flare-ups. Secondary progressive MS (SPMS) can develop after years of relapsing-remitting MS, when symptoms start to worsen more steadily.

There is no single way to have MS. Two people with the same diagnosis can have very different lives.

How MS Can Look Different

People with MS experience the world in many ways. Not everyone has all of these symptoms.

Fatigue and Energy

  • MS fatigue is one of the most common symptoms. It is not just being tired. Sleep does not always fix it.
  • Heat can make symptoms worse. Even a small rise in body temperature can have a big impact.
  • Managing energy by spacing out tasks, called pacing, is a real and useful tool.

Mobility and Movement

  • Some people use mobility aids like canes, walkers, or power wheelchairs, sometimes all the time, sometimes only when needed.
  • MS can cause muscle stiffness, tremors, weakness, or balance problems.
  • How a person moves can change from day to day or even hour to hour.

Thinking and Memory

  • Many people with MS have trouble with memory, focus, finding words, or thinking quickly. This is sometimes called “cog fog.”
  • These symptoms are real and can make daily tasks hard, even when they are not easy to see.
  • Extra time, written reminders, and a quiet space can help a lot.

Vision and Feeling

  • Eye pain or blurry vision, called optic neuritis, is a common MS symptom. It is sometimes the first sign a person notices.
  • Numbness, tingling, and pain can happen in any part of the body.
  • These symptoms can come and go and may change over time.

These differences are not personal failures. Most barriers stem from spaces and systems not built with MS in mind.

MS at Every Stage of Life

MS is not just one type of person’s experience. People with MS are young adults, middle-aged, and older. They work in every field and live in every kind of community. MS is most often diagnosed between the ages of 20 and 50. That means many people are managing it while also working, raising families, and building their lives.

MS is hard to predict. Someone who has few symptoms today may face more challenges later. Someone who has had a harder time may go through long stretches of feeling stable. What a person needs can change a lot over the years.

Having access to good medical care, helpful technology, and inclusive spaces matters at every age. MS does not decide what a person can do. Access does.

Language Matters

Many people with MS prefer to be called a “person with MS” or “person living with multiple sclerosis.” Some prefer another language. The best thing to do is to use the words a person chooses for themselves.

Try not to use language that makes MS sound like a tragedy. Avoid phrases like “confined to a wheelchair,” “battling MS,” or “suffering from.” Instead, focus on access, tools, and inclusion.

Use: person with MS, person living with multiple sclerosis, wheelchair user (when accurate)

Avoid: “confined to a wheelchair,” “battling MS,” “suffering from,” or language that treats MS as a tragedy

What Inclusion Looks Like in Daily Life

Inclusion is about real actions. It shows up in how we design spaces, set up workplaces, and share information.

  • Allow flexible hours and the option to work from home. Fatigue and changing symptoms are real.
  • Share information in writing, not just out loud. Memory and processing challenges are common.
  • Make sure buildings are easy to get around: no steps, accessible restrooms, and places to sit and rest.
  • Make digital content accessible: use clear headings, add alt text to images, and ensure the site is keyboard-accessible.
  • Keep spaces cool when possible. Heat is a real barrier for many people with MS.
  • Do not ask people to prove their diagnosis to get support. Focus on what helps, not on paperwork.
  • Trust people when they describe symptoms that are hard to see. Fatigue, pain, and brain fog are real.

These steps help people with MS take part fully. They also make spaces work better for everyone.

Listening to People with MS

People living with MS know their own lives best. When we include their voices in building products, workplaces, and services, and pay them fairly for that input, everything gets better.

The Day in the Life podcast shares real stories from people living with MS. These stories remind us that there is no single MS experience. There are many stories, told by those who live them.

MS is part of our community. When we design for access, everyone benefits.
