Myths About Multiple Sclerosis: Separating Fact from Fiction

When a diagnosis of multiple sclerosis (MS) arrives, so do many ideas picked up here and there, and not all of them are true. Some create unnecessary fear. Here we review the most common ones.

What it is, in a nutshell

MS is a disease of the central nervous system (the brain, optic nerves and spinal cord). The immune system, which normally defends us, mistakenly attacks myelin, the layer that covers nerve fibers and helps messages travel quickly. When myelin is damaged, communication between the brain and the body is disrupted.

Myth 1: "It's contagious"

No. MS is not spread through contact, through the air, or by living with a person who has it. You can hug, share a table and provide care without any risk of contagion.

Myth 2: "It's hereditary, so my children will get it"

MS is not directly inherited. Several factors are believed to play a role, including a certain genetic predisposition and environmental elements. Having a relative with MS may slightly increase the risk, but the vast majority of children of people with MS do not develop it.

Myth 3: "Everyone ends up in a wheelchair"

MS is highly variable: each person's course is different. Many people continue to walk and maintain their independence for years, and current treatments have greatly improved the outlook. Some people need mobility aids, and that is part of the diversity of the disease, not an inevitable fate.

Myth 4: "It only affects movement"

Symptoms are very diverse. They can include:

• Intense fatigue, which does not always improve with rest.
• Vision changes.
• Tingling or loss of sensation.
• Balance problems.
• Changes in attention, memory or speed of thinking.
• Changes in mood.

Many of these symptoms are "invisible": they can't be seen from the outside, but they affect daily life. That is why it is important to believe and respect what the person tells you.

Myth 5: "You must avoid exercise and exertion"

For a long time rest was recommended, but today adapted physical activity is generally considered beneficial. That said, it must be tailored to each person. Some people notice that heat temporarily worsens their symptoms, and they usually improve as the body cools down. The rehabilitation team can help design a safe plan.

Myth 6: "There is no treatment"

Although there is currently no definitive cure, treatments do exist. Some therapies help reduce relapses (episodes in which symptoms appear or worsen) and slow progression, and others relieve specific symptoms. Rehabilitation (physiotherapy, occupational therapy, speech therapy and cognitive stimulation) also helps maintain function and quality of life.

Myth 7: "You can't lead a normal life with MS"

Many people study, work, travel, raise a family and pursue their hobbies. It may be necessary to adjust your pace or ask for support, but the diagnosis does not define everything a person can do. If you have questions about pregnancy, work or medication, it is best to discuss them with your medical team.

What you can do

• Ask your healthcare team and avoid relying only on what social media or acquaintances say.
• Look for reliable sources, such as your neurologist and patient associations.
• Pace your energy: alternate activity and rest, and plan important tasks for the hours when you have more energy.
• Look after your cognitive and emotional health: if you notice changes in memory, attention or mood, mention them; strategies and support are available.
• Talk to your family: explaining invisible symptoms helps them understand you better.

To remember

Clear information reduces fear. Multiple sclerosis is complex and different in every person, but it is not contagious, it does not always lead to severe disability, and there are treatments and support available. If you have any questions about your own case, consult your healthcare team.
