Introduction

Multiple sclerosis (MS) is a complex and often misunderstood autoimmune disease that affects millions of people worldwide. In this article, we will explore the global statistics of MS, its symptoms, risk factors, and how it can be managed. We’ll also discuss why MS is on the rise in developing countries and what governments can do to protect their citizens.

What is multiple sclerosis?

Multiple sclerosis is a chronic autoimmune condition where the immune system mistakenly attacks the protective covering of nerves, known as myelin. This damage disrupts communication between the brain and the rest of the body, leading to a wide range of symptoms. MS primarily affects the brain and spinal cord, and its symptoms can vary significantly from person to person.

Common symptoms include:

• Blurred vision or pain in the eyes
• Numbness or tingling in different parts of the body
• Feeling off balance, dizzy, or clumsy
• Muscle cramps
• Increased need to urinate or loss of bladder control
• Problems with memory or concentration

Symptoms may come and go in episodes known as "flare-ups" or "relapses," followed by periods of “remission” where symptoms improve or disappear. Sufferers of multiple sclerosis should avoid stress and keep warm, as extreme cold aggravates the problem.

 

Global Statistics of Multiple Sclerosis

According to the World Health Organisation (WHO), over 2.8 million people worldwide are living with MS. The National Multiple Sclerosis Society of Kenya had 150 members in 2022.

 The prevalence of MS varies from region to region, with higher rates in North America and Europe compared to Asia and Africa. However, cases are increasing in developing countries, possibly due to improved diagnostics and changing environmental factors.

 Prevalence: The geographical distribution of MS reveals a higher prevalence in temperate regions, further from the equator. This observation has led to extensive research into potential environmental factors, such as vitamin D levels (influenced by sunlight exposure) and specific infections, that may contribute to the disease's development. The reasons for this disparity are not fully understood.

 Age of Onset: MS diagnosis typically occurs between 20 and 40, a period often coinciding with peak life activities. While less frequent, MS can affect individuals outside this range. Its occurrence in childhood is rare, prompting clinicians to initially investigate other potential paediatric conditions before considering MS as a diagnosis.

 Gender Disparity: Women are 2-3 times more likely to develop MS than men. Researchers believe this disparity is linked to hormonal differences, particularly oestrogen, which may play a role in the immune system regulation. Additionally, genetic factors and environmental triggers may contribute to the higher risk in women. In a study at the Aghakhan Hospital in Nairobi in 2008, for every one man with MS, there were four women.

Courses of Multiple Sclerosis

MS can manifest in different ways, and its course varies from person to person. The main types of MS include:

1. Relapsing-Remitting MS (RRMS): The most common form, characterised by flare-ups followed by periods of remission.
2. Primary Progressive MS (PPMS): Symptoms gradually worsen over time without distinct relapses.
3. Secondary Progressive MS (SPMS): Initially starts as RRMS but later transitions to a progressive form.
4. Progressive-Relapsing MS (PRMS): A rare form where symptoms steadily worsen, with occasional relapses.

Symptoms may shift over time, striking different areas of the body with variable severity.

How is multiple sclerosis diagnosed?

Diagnosing MS can be challenging because its symptoms overlap with other conditions. Doctors typically use a combination of methods, including. These include 1. Medical History and Neurological Exams to assess symptoms and rule out other conditions; 2. Magnetic Resonance Imaging (MRI) to detect lesions or damage in the brain and spinal cord; 3. Lumbar Puncture to analyse cerebrospinal fluid for markers of MS; and 4. Blood Tests to rule out other diseases with similar symptoms.

While there is no cure for MS, early diagnosis and treatment can help manage symptoms and slow the progression of this disease.

How Can One Protect Themselves from Multiple Sclerosis?

While the precise cause of multiple sclerosis remains unclear, research suggests that certain lifestyle modifications may influence the risk or severity of the disease. Maintaining adequate vitamin D levels is crucial, as deficiency has been linked to increased risk. Avoiding smoking is also vital, as it's a known risk factor and can worsen symptoms. A balanced diet, rich in fruits, vegetables, and omega-3 fatty acids, supports overall health. Regular exercise can improve strength, balance, and mood, potentially mitigating some MS symptoms. These measures promote general well-being and might contribute to reducing the impact of MS. In brief:

• Maintain Adequate Vitamin D Levels: Low vitamin D has been linked to a higher risk of MS.
• Avoid Smoking: Smoking is a known risk factor for MS and can worsen symptoms.
• Eat a Balanced Diet: A diet rich in fruits, vegetables, and omega-3 fatty acids may support overall health.
• Exercise Regularly: Physical activity can improve strength, balance, and mood in people with MS.

Why is multiple sclerosis increasing in the Third World?

The rise of MS in developing countries can be attributed to several factors. This includes improved diagnostics.  Better access to healthcare and advanced imaging techniques has led to more accurate diagnoses. Previously, MS may have been misdiagnosed, leading to treatment for other ailments.

Urbanisation, sedentary lifestyles, and dietary changes may contribute to increased risk. People are drinking more and doing very little exercise as people travel more in vehicles as lifestyles change.

Environmental factors also play a role.  Exposure to pollutants, infections, and low sunlight (vitamin D deficiency) may be some of the consequences. Microplastics are in villages and towns in developing nations—in the air, water, and even in the flesh of fish. 

What Policies Should Governments Put in Place to Protect Citizens from Multiple Sclerosis?

It's clear that governments have a big role to play in tackling MS. One key thing is raising awareness. Public health campaigns can really help people understand the symptoms and why early diagnosis is so important.

Improving access to healthcare is also crucial. We've seen some innovative approaches, like mobile clinics reaching pastoralist communities. But governments need to go further, ensuring that everyone, no matter where they live, can afford and access the tools to get diagnosed and the treatments they need.

Supporting research is another vital area. Universities and research organisations need funding to dig deeper into what causes MS and how we can develop more effective treatments.

Finally, health ministries can promote healthier lifestyles. Campaigns encouraging people to be more active, eat well, and quit smoking can help reduce risk factors.

Beyond those points, it's important to remember that MS requires a holistic approach. Long-term management involves not just medications but also things like physical, occupational, and speech therapy. And we can't forget the mental health side of things—depression, anxiety, and fatigue are common, so addressing those is essential.

MS also has a significant economic impact, both on individuals and on the wider healthcare system. This includes everything from the cost of treatment to lost productivity. So, governments need to look at cost-effectiveness to make the best decisions about how to allocate resources.

Conclusion

May 30th marks International Multiple Sclerosis Day, a crucial occasion to recognize and support those living with this complex neurological condition. Multiple sclerosis presents significant challenges, affecting the central nervous system and impacting various bodily functions. However, it is essential to emphasise that with comprehensive management strategies, including medical treatments, rehabilitation therapies, and robust support networks, individuals with MS can lead meaningful and fulfilling lives. This annual observance serves as a vital platform to amplify awareness about MS, advocate for improved healthcare access and resources, and encourage the adoption of healthy lifestyles that can positively influence the well-being of those affected. By collectively increasing understanding and fostering supportive environments, we can work towards reducing the overall impact of MS on individuals and communities across the globe. Early detection is paramount; therefore, if you or someone you know is experiencing any symptoms suggestive of MS, it is crucial to seek prompt medical advice for timely intervention and the best possible outcomes.
