Multiple Sclerosis (MS) is a chronic neurological condition that affects the central nervous system. It causes a range of symptoms that can vary widely among individuals. For people with MS, life tends to be shorter, but not always. MS and life expectancy depend on the onset of the disease, the type of MS, and the symptoms each person experiences.
Is there something I can do to prevent MS from affecting my life expectancy? Recent advancements are shortcutting the gap between the life expectancy of people with and without MS. You, too, can learn about what is helpful for MS. Join us!
What causes Multiple Sclerosis?
Multiple Sclerosis is an autoimmune disorder where the immune system mistakenly attacks the protective covering of nerve fibers, called myelin. This disrupts communication between the brain and the rest of the body, leading to many symptoms, such as fatigue, numbness, muscle weakness, and difficulties with coordination and balance.
Types of MS
Some people with MS experience periods of remission, where symptoms improve or disappear entirely, while others may face a more progressive decline in neurological function.
- Relapsing-remitting: The person experiences episodes of symptoms sporadically, called relapses, and then recovers slowly over time. This type of MS affects 8-9 out of 10 patients. A relapse could last days or months, as could the recovery period.
- Primary progressive: in this type of MS, the symptoms slowly get worse over the years. Affects around 1-2 in 10 people with MS.
- Secondary progressive: around 66% of people with relapsing-remitting MS evolve to this form of MS, characterized by a gradual worsening of symptoms and no obvious attacks. Relapses could happen, although they are infrequent.
MS and life expectancy
Overall, people with MS tend to live around 5 to 10 years less compared to people without the disease. Still, this difference is getting smaller thanks to improvements in therapy and understanding of MS.
MS and life expectancy have improved dramatically in the last years, also thanks to the patients themselves, who are engaged in their improvement.
Calculating life expectancy for individuals with MS is hard because of the highly variable and unpredictable course of the disease. The severity and progression of MS can differ greatly from person to person, making it difficult to establish a one-size-fits-all prognosis.
What factors influence MS and life expectancy?
Some of the factors that impact life expectancy in MS patients:
Age at Diagnosis
The age at which a person is diagnosed with MS can influence life expectancy. Onset during early adulthood may present different challenges than at a later onset and could be associated with reduced life expectancy.
Disease Course
The type of MS, whether relapsing-remitting or progressive, plays a crucial role in determining the progression of the disease and, consequently, life expectancy. Some people develop secondary progressive MS after years of relapsing-remitting MS.
Gender
Studies suggest that women are more likely to be diagnosed with MS than men. The impact of gender on life expectancy in MS is an area of ongoing research, and it is not clear if women with MS have shorter lives compared with men.
Access to Treatment
Advances in MS treatment options have significantly improved over the years. Early diagnosis and access to appropriate therapies can help manage symptoms and potentially slow disease progression, positively impacting life expectancy.
Evolving Treatment Landscape
Over the past few decades, significant progress has been made in the development of disease-modifying therapies (DMTs) for MS. These medications aim to alter the course of the disease, reduce relapses, and manage symptoms effectively. The availability of these treatments has provided new hope for individuals living with MS, offering improved quality of life and potentially influencing the duration of their lives.
Quality of Life Considerations
Individuals with MS, along with their healthcare providers, focus on managing symptoms, maintaining independence, and addressing the emotional and psychological aspects of the disease.
Adaptive technologies, rehabilitation programs, and support networks significantly enhance the overall well-being of people with MS.
Lifestyle and healthy habits
Smoking and obesity could worsen the symptoms and decrease life expectancy for people living with MS. Taking care of other medical problems they may have can help improve the lives of people with MS.
Studies show that people with MS can benefit from a healthy lifestyle. MS and life expectancy improve when people with MS engage in a healthy lifestyle. Following a Mediterranean diet, practicing sports regularly, and taking care of their emotional health are helpful for improving the quality of life and increasing the life expectancy in people with MS.
Research and Future Perspectives on MS and life expectancy
Ongoing research deepens our understanding of MS and its complexities. As scientists explore new treatment avenues and delve into the genetic and environmental factors influencing the disease, the landscape of MS and life expectancy is likely to evolve further.
This continuous pursuit of knowledge holds promise for improved therapies, better prognostic tools, and enhanced support for those living with MS.
Key points
- Multiple Sclerosis is a complex and dynamic condition that challenges both individuals diagnosed with the disease and healthcare professionals seeking to manage its impact.
- While influenced by various factors, life expectancy is just one aspect of the broader picture. Advances in treatment options, coupled with a holistic approach to care, are transforming the outlook for people with MS.
